Affective Responses to Acute Exercise: A Meta-Analysis of the Potential Beneficial Effects of a Single Bout of Exercise on General Mood, Anxiety, and Depressive Symptoms.

Acute exercise elicits various biobehavioral and psychological responses, but results are mixed with regard to the magnitude of exercise-induced affective reactions. This meta-analysis examines the magnitude of general mood state, anxiety, and depressive symptom responses to acute exercise while exploring exercise protocol characteristics and background health behaviors that may play a role in the affective response. A total of 2770 articles were identified from a MEDLINE/PubMed search and an additional 133 articles from reviews of reference sections. Studies had to have measured general mood before the acute exercise bout and within 30 minutes after exercise completion. Effect sizes were estimated using Hedges' g , with larger values indicating improvement in the outcome measure. A total of 103 studies were included presenting data from 4671 participants. General mood state improved from preexercise to postexercise ( g = 0.336, 95% confidence interval [CI] = 0.234-0.439). Anxiety ( g = 0.497, 95% CI = 0.263-0.730) and depressive symptoms ( g = 0.407, 95% CI = 0.249-0.564) also improved with exercise. There was substantial and statistically significant heterogeneity in each of these meta-analyses. This heterogeneity was not explained by differences in participants' health status. Meta-regression analyses with potential moderators (intensity of exercise, mode of exercise, usual physical activity level, or weight status of participants) also did not reduce the heterogeneity. This meta-analysis shows significantly improved general mood, decreased anxiety, and lower depressive symptoms in response to an acute bout of exercise. There was substantial heterogeneity in the magnitude of the effect sizes, indicating that additional research is needed to identify determinants of a positive affective response to acute exercise.

Impaired muscle oxygenation despite normal pulmonary function in type 2 diabetes without complications.

Long-term hyperglycemia in individuals with type 2 diabetes (T2D) can detrimentally impact pulmonary function and muscle oxygenation. As a result, these factors can impede the body's adaptation to physical exertion. We aimed to evaluate the oxygen pathway during maximal exercise among overweight/obese individuals with type 2 diabetes free from complications, in comparison with a group of matched overweight/obese individuals without diabetes, specifically concentrating on the effects on pulmonary function and muscle oxygenation. Fifteen overweight/obese adults with type 2 diabetes [glycated hemoglobin (HbA1c) = 8.3 ± 1.2%] and 15 matched overweight/obese adults without diabetes underwent pre- and post exercise lung function assessment. A maximal incremental exercise test was conducted, monitoring muscle oxygenation using near-infrared spectroscopy and collecting arterial blood gas samples. Both groups exhibited normal lung volumes at rest and after exercise. Spirometric lung function did not significantly differ pre- and post exercise in either group. During maximal exercise, the type 2 diabetes group showed significantly lower augmentation in total hemoglobin and deoxygenated hemoglobin compared with the control group. Despite comparable usual physical activity levels and comparable heart rates at exhaustion, the type 2 diabetes group had a lower peak oxygen consumption than controls. No significant differences were found in arterial blood gas analyses ([Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text]) between the groups. Individuals with type 2 diabetes free from complications displayed normal pulmonary function at rest and post exercise. However, impaired skeletal muscle oxygenation during exercise, resulting from reduced limb blood volume and altered muscle deoxygenation, may contribute to the lower V̇o2peak observed in this population.NEW & NOTEWORTHY Individuals with type 2 diabetes free from micro- and macrovascular complications have normal resting pulmonary function, but their V̇o2peak is impaired due to poor skeletal muscle oxygenation during exercise. Tailoring exercise regimes for this population should prioritize interventions aimed at enhancing muscle oxygenation and blood flow improvement.

Development and validation of the physical effort scale (PES)

ObjectivesPrevious literature has primarily viewed physical effort as an aversive experience. However, recent research suggests that effort can also be valued positively. These differences in approach and avoidance tendencies toward physical effort may play a key role in the self-regulation of physical activity behaviors. The aim of this study was to develop a scale that measures these tendencies and contributes to a better understanding of physical effort and how it affects behavior. MethodsThe Physical Effort Scale (PES) was developed in Study 1 based on expert evaluations (n = 9) and cognitive interviews (n = 10). In Study 2 (n = 680, 69% female), content validity and dimensional structure were examined using principal component analysis and confirmatory factor analysis. Item reduction was conducted using item response theory. Preliminary construct validity was explored using regression. Study 3 (n = 297, 71% female) was used to validate dimensional structure, internal consistency, and construct validity, and to assess test-retest reliability. ResultsIn Study 1, 44 items were rated for content validity, of which 18 were selected and refined based on cognitive interviews. Analyses from Study 2 allowed reducing the scale to 8 items with a two-dimension structure: tendency to approach (n = 4) and to avoid physical effort (n = 4). The two subscales showed high internal consistency (α = 0.897 for the approach dimension and 0.913 for the avoidance dimension) and explained usual levels of physical activity, providing preliminary evidence of construct validity. Study 3 confirmed the two-dimension structure with high internal consistency (α = 0.907 and 0.916 for the approach and avoidance dimension, respectively) and revealed acceptable test-retest reliability (intraclass correlation >0.66). Patterns of associations with other constructs showed expected relationships, confirming the concurrent, convergent, and discriminant validity of the scale. ConclusionsThe PES is a valid and reliable measure of individual differences in the valuation of physical effort. This scale can assess the propensity to engage in physically demanding tasks in non-clinical populations. The PES and its manual are available in the Supplementary Material.

Association between Diet and Adiposity in Adults: Influence of Sedentary Behavior Patterns.

This study analyzed the influence of sedentary behavior (SB) on the association between dietary patterns and adiposity in community-dwelling adults. Eight hundred and forty-three adults (age: 56.5 ± 18.3 years) participated in this cross-sectional epidemiological study. Dietary patterns were evaluated using self-report questions regarding the weekly frequency of consumption of certain foods. Adiposity was determined using anthropometric measurements of weight, waist circumference, and height. SB was evaluated according to the time spent on screen devices. The usual physical activity level and socioeconomic status were considered confounding factors. Associations were determined using multivariate linear models with simultaneous adjustments for confounding variables. A statistical analysis indicated that fruit consumption was negatively related to the body mass index, regardless of the adjustment for SB domains. Red meat consumption was positively related to the body mass index, and fried food consumption was positively related to the waist-to-height ratio, regardless of the adjustment for SB domains. The consumption of fried food was positively associated with global and central adiposity after the adjustments for confounding factors and time spent on screen devices. We concluded that dietary habits are related to adiposity in adults. However, SB domains seem to influence the relationship between body adiposity and dietary habits, mainly regarding the consumption of fried foods.

Physical development of adolescents with different levels of motor activity

As part of the study, the physical development of adolescents was evaluated depending on the level of daily motor activity and individual anthropometric indicators of professional athletes. The physical development indicators of 423 boys aged 16 to 18 years were analyzed, which were divided into 3 groups depending on the level of daily physical activity: professional athletes, with additional physical activity, with the usual level of physical activity. The data were collected as a result of a routine medical examination in the period from June to October 2022. The results showed that children aged 16 and 17 with a normal level of motor activity were statistically significantly lower and had less body weight compared to the other groups. The analysis of the fatness index also confirmed the data obtained in the age group of 18‑year-olds. The largest proportion of children (at 16 years — 17.6 %; at 17 years — 33, %) with disharmonious or distinct disharmonious physical development was revealed in the group of children with normal physical activity; no cases of distinct disharmonious level of physical development were found among adolescent athletes. Statistically significant differences in anthropometric indicators among professionally engaged in sports adolescents aged 16 to 18 years were not revealed, while in children with a normal level of physical activity in these age groups, changes in indicators are pronounced, which may indicate an earlier and smoother biological development of adolescent athletes. The use of mass-growth indicators makes it possible to more accurately assess the achieved level of physical development and the level of its harmony.

Bio substrate microelement concentrations in young men — residents of the Far North — under increased physical exercises

BACKGROUND: High-level athletic competitions necessitate more strenuous physical activity and this upsets the bodys chemistry balance. Numerous mechanisms are in place during sports to adapt to regular physical activity, but as a result, the body is progressively stressed out as it experiences a high loss in the bio-elements associated with intense exercise.
 AIM: to thoroughly analyze the chemical profiles of athletes residing in the city of Magadan, who have achieved great sporting success, and to identify the unique features of microelement concentrations in subjective samples (hair, whole blood).
 MATERIALS AND METHODS: The study was conducted to analyze elemental pictures of high-level athletes in the city of Magadan who were between the ages of 19 and 25 (n=29). Age-matched men who showed usual levels of physical activity comprise the control group (n=22). Different biological substrates (hair and whole blood, among others) were examined to determine the most informative substrate for the identification of the most common types of chronic elemental imbalance. This was considered particularly important for further prevention of typical region-related disorders in the body chemistry by increasing functional reserves. Eighteen macro- and microelements were examined via atomic emission and mass spectrometric methods with inductively coupled argon plasma.
 RESULTS AND DISCUSSION: The athletes examined in the present study exhibited higher levels of Ca, Co, Fe, Se, and Zn in their hair samples and showed higher median concentrations of blood Na and P, and an excess levels of blood Mn, when compared with the subjects who had moderate levels of physical activity and whose blood examination showed higher values of K, Mg, Co, Fe, Se, the deficiency of Co, Cu, Zn, and Fe, and excess of Mg and Se.
 CONCLUSION: However, data obtained in the present study did not enable us to explicitly draw inferences regarding sports-induced changes in the body microelement profile. In some cases, the elemental profile of athletes is similar to that of residents of Magadan and they show a typical northern type of deficiency in essential elements expressed in the hair. Notably, the frequency of hair deficits is frequently higher in young men who experience no increased exercise levels. Excessive toxic elements or heavy metals were not identified biological substrates examined in the present study. It was our understanding that long-term assessment of the athletes elemental imbalance which is formed under intense physical activity can be performed through spectral hair analysis. This is attributable to the fact that it is an accumulative bio substrate that shows no day-to-day fluctuations under changeable functional or psychoemotional states, as well as nutrition preferences.

유마니튜드 케어댄스 프로그램이 노인의 건강한 삶에 미치는 긍정적 영향 -신체기능과 인지기능을 중심으로-

This study was conducted to confirm the effect on the physical function and cognitive function of the elderly by applying a Humanitude Care Dance program twice a week for 6 weeks for men and women aged 65 or older. The experimental groups(n=10) who participated in the program and the control group (n=10) who maintained their usual physical activity levels were examined how muscle strength, endurance, and cognitive function changed before and after. For data processing, the average value (M) and standard deviation (SD) were calculated using the SPSS 23.0 program for Windows. As a result of the study, the elderly''s physical function improvement and cognitive function were higher after performing the program, confirming that this program was effective.

ETAPAS DO ENVELHECIMENTO REPRODUTIVO: EFEITOS NOS NÍVEIS DE ADIPOSIDADE, ATIVIDADE FÍSICA E VISITA À NATUREZA

Introduction: Menopause marks an extensive period of hormonal changes in women. Estrogen depletion, combined with the aging process, increases fat mass, particularly intra-abdominal fat, and generates a decrease in muscle and bone mass, affecting women's usual levels of physical activity (PA) and compromising their quality of life. Exposure to the natural environment confers numerous health benefits, however, much remains unknown about the differences in the nature visits according to a woman's reproductive stages, and often PA levels are measured through questionnaires. Purpose: This study analyzed the variation of adiposity levels, PA and nature visits according to the stages of reproductive aging in women. Methods In this cross-sectional study, women aged 18 to 75 were categorized in the reproductive age (G1, n=94), menopausal transition (G2, n=12) and postmenopause (G3, n=36), considering the reproductive aging stages described in STRAW +10. Fat mass (FM, %) and visceral fat area (VFA) were assessed by octopolar bioimpedance (InBody 720). Physical activity (moderate-vigorous and steps/day) was measured using ActiGraph accelerometers (wGT3X-BT) and nature visits were assessed through a questionnaire. Analyses of variance were used to analyze the data. Some transformations of the variables were conducted, to normalize their distribution (moderate-vigorous PA) or to improve their asymmetry (VFA and nature visits). The standard significance level was set a p ≤0.05. Results: A higher percentage of women with obesity (%FM and VFA) and non-recommended levels of moderate-vigorous PA were recorded in group 3 (77.8%, 83.3%, and 72.2% respectively). Half of the women in G2 had high levels of total and central adiposity and levels of MVPA <150 minutes/week. Our results showed that women in G1 had lower percentage (p 0.01) FM values (28.24%) than those exhibited by women in G2 (34.25%) and G3 (36.55%), with 24% of the relative fat mass variation explained by the reproductive aging stages. For a type I error <0.05, there was a greater than 99% probability that percentage FM values varied with reproductive aging stages. The variation of VFA was also explained by reproductive aging stages by 46%, and differences (p <0.01) were identified between groups G1-G2 and G1-G3. Our results further documented that with reproductive aging, there is a decrease in moderate-vigorous PA levels, and differences (p <0.01) were observed between G1-G3. No differences were observed between reproductive stages for steps/day (p >0.05) and nature visits (p =0.17). Conclusions: Our results suggest that postmenopausal women evidence increased levels of total and central adiposity and simultaneously, limited levels of physical activity compared to women in the reproductive phase. These findings underline the need to implement PA programs oriented to weight control and to encourage the regular practice of PA adjusted to the needs evidenced by these women, contributing to a better quality of life for them.

Within-Person Associations Among Physical Activity, Sleep, and Well-being in Situ: Opportunities for Whole-Person Well-being

Background Digital tools can help cultivate states of well-being through psychological interventions. Interventions and policies with the most promise of influencing individual and population health and well-being in real-world contexts require understanding the dynamic relationships between different domains of well-being in daily life. Objective This study aimed to consider multiple components of the health behavior–well-being system to identify potential targets for designing ecologically relevant interventions in everyday life. Methods We used self-reported affective states, purpose in life, and physical activity collected via smartphone-based experience sampling twice per day over 28 days as participants (N=226 young adults; mean age 20.2, SD 1.7 years; 76% women and 25% men) went about their daily lives. We used a multilevel vector autoregressive model to isolate within- and between-person relationships among daytime physical activity, nighttime sleep duration, nighttime sleep quality, happiness, sadness, anger, anxiousness, and purpose in life. This approach generates 3 networks describing the relationships among variables of interest: (1) a directed temporal network revealing within-person, time-lagged, previous-day relationships among variables; (2) a contemporaneous undirected network revealing within-person same-day relationships among variables; and (3) an undirected between-person network identifying between-person differences in how variables are associated with one another. Results Our complex-system approach to the health behavior–well-being system revealed significant interplay among physical activity, sleep, affect, and purpose in life. We found that when an individual had higher than their usual levels of physical activity on a particular day, they experienced an increase in happy affect the next day. Higher sleep quality on a particular day also predicted a decrease in negative affective states the next day. We found that purpose in life predicted decreased sad, anxious, and angry affect up to 2 days later. For contemporaneous relationships, higher than usual happiness predicted increased purpose in life and lower anger, anxiety, and sadness on the same day. We found that people who, on average, were happier tended to endorse a higher sense of purpose in life and experience increased sleep quality, whereas people who, on average, were sadder tended to have increased anxiety and anger. Conclusions Collectively, these findings suggest that behavioral interventions targeting sleep and physical activity may observe shorter-term (up to 1 day) effects on well-being, whereas interventions cultivating a sense of purpose in life can have slightly longer effects on well-being, bleeding into the next few days. Our findings suggest that approaches simultaneously considering whole-person well-being rather than just one domain of well-being hold promise for informing the design of behavior interventions with the most promise of influencing health in real-world contexts. Moving forward, digital health tools should incorporate tracking multiple domains of well-being in daily life to increase opportunities for whole-person health approaches in virtual care settings. Conflicts of Interest None declared.

Physical Activity in Patients With Heart Failure During and After COVID-19 Lockdown: Single-Center Observational Retrospective Study.

BackgroundThe COVID-19 pandemic forced several European governments to impose severe lockdown measures. The reduction of physical activity during the lockdown could have been deleterious.ObjectiveThe aim of this observational, retrospective study was to investigate the effect of the lockdown strategy on the physical activity burden and subsequent reassessment in a group of patients with heart failure who were followed by means of remote monitoring.MethodsWe analyzed remote monitoring transmissions during the 3-month period immediately preceding the lockdown, 69 days of lockdown, and 3-month period after the first lockdown in a cohort of patients with heart failure from a general hospital in Lombardy, Italy. We compared variation of daily physical activity measured by cardiac implantable electrical devices with clinical variables collected in a hospital database.ResultsWe enrolled 41 patients with heart failure that sent 176 transmissions. Physical activity decreased during the lockdown period (mean 3.4, SD 1.9 vs mean 2.9, SD 1.8 hours/day; P<.001) but no significant difference was found when comparing the period preceding and following the lockdown (–0.0007 hours/day; P=.99). We found a significant correlation between physical activity reduction during and after the lockdown (R2=0.45, P<.001). The only significant predictor of exercise variation in the postlockdown period was the lockdown to prelockdown physical activity ratio.ConclusionsAn excessive reduction of exercise in patients with heart failure decreased the tolerance to exercise, especially in patients with more comorbidities. Remote monitoring demonstrated exercise reduction, suggesting its potential utility to encourage patients to maintain their usual physical activity levels.

Effect of One Month Exposure to Components of Reprometabolic Syndrome on Physical Activity &amp; Body Composition in Lean Women

Abstract Background: Subfertility in obese women is associated with chronic pituitary suppression, reduced sensitivity to GnRH and decreased sex steroid production. We have found evidence for a combined effect of hyperinsulinemia and high circulating fatty acids to acutely (4h infusion) suppress pituitary gonadotropin secretion and are currently investigating the effects of one-month exposure to a eucaloric high-fat diet (HFD) on gonadotropin levels in lean women. The aim of this study is to examine the effect of the one-month HFD on physical activity and body composition. Methods: 12 normal weight (BMI &amp;lt; 25 kg/m2), normally cycling female participants of reproductive age were given a one-month eucaloric HFD, from the onset of menses in one cycle through the next, with 48% calories from fat. A Fitbit was provided to monitor changes in daily activity and sleep throughout the study. Measurement of gonadotropin pulsatility and reproductive hormones were done using frequent blood sampling and daily urine excretion, respectively. These measurements were obtained for a total of 4 menstrual cycles: 1 pre-diet cycle, the HFD cycle, and 2 post-diet cycles. DEXA body composition was measured at baseline and at the end of the 2nd post diet cycle. Pre and post diet comparisons were done using linear mixed model testing and reported as estimated means ± standard error. Results: Mean number of daily steps were (9,226 ± 1,140) pre diet, (9,132 ± 1,140) during the diet and (7,533 ± 1,140) post diet. Daily active calories were (1,982 ± 99) pre diet, (1,975 ± 99) during the diet and (1,856 ± 99) post diet. Means in the HFD cycle did not differ from the pre-diet cycle. Daily sleeping minutes pre diet were (443 ± 19), (451 ± 20) during the diet and (412 ± 19) post diet, with no statistical difference between the 3 time points. BMI did not differ between pre-diet (21.84 ± 0.52) and post-diet (21.77 ± 0.52). DEXA body composition measurements indicated a statistically significant decrease in total fat percentage, (32.26 ± 1.53) pre diet and (31.31 ± 1.53) post diet, which does not appear clinically significant as the difference of less than 1% falls within the anticipated measurement error of the method. Visceral fat volume (cm3) did not differ between pre diet (299.51 ± 27.76) and post diet (295.53 ± 27.76). Conclusions: The complete cohort has not yet been fully recruited and analyzed. These preliminary findings indicate that women consuming a one-month, HFD maintain their usual level of physical activity and sleep patterns, and do not appear to sustain change in visceral fat. Further accrual of participants should clarify the small decrease in total body fat observed without a change in BMI.

Individual Differences in Cross-System Physiological Activity at Rest and in Response to Acute Social Stress.

Individual differences in long-term cardiovascular disease risk are related to physiological responses to psychological stress. However, little is known about specific physiological response profiles in young adults that may set the stage for long-term increased cardiovascular disease risk. We investigated individual differences in profiles of resting cardiovascular physiology and stress reactivity, combining parasympathetic, sympathetic, and hemodynamic measures. Participants (n = 744, 71% women, mean [standard deviation] age = 20.1 [2.4] years) underwent the Trier Social Stress Test, while blood pressure (systolic blood pressure, diastolic blood pressure), electrocardiograms (interbeat interval), and impedance cardiograms (preejection period, left ventricular ejection time) were recorded. Respiratory sinus arrhythmia was derived from the combination of the electrocardiogram and the impedance cardiogram. A three-step latent profile analysis (LPA) was performed on resting and reactivity values to derive clusters of individual physiological profiles. We also explored demographic and health behavioral correlates of the observed latent clusters. For resting physiology, LPA revealed five different resting physiology profiles, which were related to sex, usual physical activity levels, and body mass index. Five cardiovascular stress reactivity profiles were identified: a reciprocal/moderate stress response (Cr1; 29%), and clusters characterized by high blood pressure reactivity (Cr2: 22%), high vagal withdrawal (Cr3; 22%), autonomic coactivation (parasympathetic nervous system and sympathetic nervous system; Cr4; 13%), and overall high reactivity (Cr5; 12%). Men were more likely to belong to the high reactivity (Cr5) cluster, whereas women were more likely to have autonomic coactivation (Cr4). We identified five cardiovascular physiological reactivity profiles, with individuals displaying generalized hyperreactivity, predominant vagal withdrawal, autonomic coactivation, or blood pressure-specific hyperreactivity. Longitudinal studies are needed to determine whether these profiles are useful in early detection of individuals at high risk for cardiovascular disease.

COVID-19 Lockdown and Changes of the Dietary Pattern and Physical Activity Habits in a Cohort of Patients with Type 2 Diabetes Mellitus.

The COVID-19 lockdown clearly affected the lifestyle of the population and entailed changes in their daily habits, which involved potential health consequences, especially on patients with Type 2 Diabetes Mellitus (T2DM). We aimed to examine the impact of the lockdown caused by COVID-19 pandemic on both nutrition and exercise habits, as well as the psychological effects in patients with T2DM, compared to their usual diet and physical activity level previous to the complete home confinement. We also intended to analyse any potential variables that may have influenced these lifestyle modifications. A Food Frequency Questionnaire (FFQ), Physical Activity Questionnaire (IPAQ), Food Craving Questionnaire-State (FCQ-S) and Food Craving Questionnaire-Trait (FCQ-T) were used. Our results showed an increase in vegetable, sugary food and snack consumption. An association between levels of foods cravings and snack consumption was also found. Data also showed a high percentage of physical inactivity before the COVID-19 lockdown, which was exacerbated during the home confinement. These findings emphasise the great importance to do further research with larger study samples to analyse and explore dietary habits and to develop public health policies to promote a healthy lifestyle in terms of diet and physical activity in these patients, especially after this strict period of lockdown.

Impact of a five-month detraining period on the functional fitness and physical activity levels on active older people

PurposeThis research was aimed at evaluating the effects of a five-month detraining period on the functional fitness level of a group of non-institutionalized and active older adults after taking part in a multi-component training program. A secondary aim was to determine how usual physical activity (PA) levels vary due to cessation of the program. MethodsWe tested sixty-five older people (mean age: 77.1 ± 6.2; 83% women) during the final week of an 8-month multi-component training program and during the first week after its resumption (five months later). We used the senior fitness test and the Minnesota Questionnaire to assess their functional fitness and their PA levels respectively. ResultsWe observed a significant worsening of lower-limb strength (p = 0.008), shoulder range of motion (p = 0.004), and dynamic balance (p < 0.001) once the detraining period was completed. There was a slight downward trend in the remaining functional fitness dimensions, and there were significant differences when comparing the amount of PA estimated at pre-detraining and post-detraining (5155 ± 2258 vs 3937 ± 2087 MET-min·wk−1; p < 0.001). Older adults classified as very active showed a non-significant trend to smaller decreases in functional fitness once the detraining period was over, in comparison with those considered active. ConclusionsActive older people who regularly participated in a multicomponent training program showed a significant reduction in their strength, range of motion, and dynamic balance levels after a five-month detraining period. Self-reported PA decreased significantly during this time frame. Effective strategies are needed to increase PA levels in older people when systematic training programs are temporarily interrupted.

Effects of aerobic exercise on cardiorespiratory fitness and social functioning in veterans 40 to 65 years old with schizophrenia

The usual physical activity level of people with chronic histories of schizophrenia is very low. In this pilot study, we examined the effects of an easy to implement aerobic exercise (AE) program on cardiorespiratory fitness and social functioning in 54 Veterans aged 40-65 years old with schizophrenia. Participants were randomized 2:1 to AE (36 forty-minute sessions conducted 3 times per week over 12 weeks) versus a non-aerobic stretching exercise condition conducted under the same regimen and timeframe. Cardiorespiratory fitness improved significantly within the AE group (p<.0001), and differed significantly from the comparison group (p<.02; Cohen's d=.41). Trend-level improvements were seen in social functioning within the AE group (p<.09) and showed a similar trend level difference in the between-group comparison (p<.06; Cohen's d=.35). Improvements in social functioning were significantly related to gains in cardiorespiratory fitness (r=.42; p<.01). AE effects on other physical and mental health indices were also examined. Overall, the AE intervention was well-tolerated, safe, and showed low rates of attrition after the commencement of training. Our findings indicate it is feasible to improve cardiorespiratory fitness in this clinical population, and there is suggestive evidence that the interventions aimed to do so may also benefit social functioning.

Effect of an interdisciplinary intervention with motivational approach on exercise capacity in obese adolescents: a randomized controlled clinical trial.

ABSTRACTObjective To evaluate the effect of an interdisciplinary intervention with a motivational approach on exercise capacity and usual physical activity levels in overweight and obese adolescents.Methods This is a randomized, controlled clinical trial with single blinding of subjects. Adolescents aged 15 to 18 years with overweight and obesity (body mass index ≥ 85 percentile) were included. The adolescents were randomized into two groups: interdisciplinary intervention or control − traditional approach aiming at lifestyle modifications. The initial evaluations were carried out, including the cardiopulmonary exercise test and the physical activity level measurement by using the International Physical Activity Questionnaire and a pedometer. The evaluations were performed in two moments: time zero (time of inclusion in the study) and after 3 months (end of intervention). There were 12 sessions with weekly meetings.Results A total of 37 participants were included, 19 in the Intervention Group. There were no significant differences in the baseline demographic, anthropometric and physical activity characteristics between groups, with mean age of 17.3±1.0 years in the Control Group, and 16.8±0.9 years in the Intervention Group (p=0.14). The motivational intervention did not cause significant differences (p>0.05) in the comparison of the variables of exercise capacity and usual physical activity (questionnaire and pedometer) between groups.Conclusion The intervention with a motivational approach did not alter exercise capacity and levels of usual physical activity in overweight and obese adolescents.Clinical Trial Registry: NCT02455973 and REBEC: RBR-234nb5.

Exercise intensity to maximal aerobic speed, physical activity level and heart rate variability in postmenopausal women

Physical inactivity is main cause of disease worldwide. Identify the physical exercise preference, resulting in increases adherence and future intention to perform physical activity. The preference of the intensity of exercise questionnaire (PRETIE-Q) is the main tool used to assess preference in physical exercise. Variables as age, body mass index (BMI), usual physical activity level (PAL), maximal oxygen uptake (VO2máx), can influence in PRETIE-Q answers. The purpose of this study was investigate if there is relation between preference for exercise intensity with maximal aerobic speed (MAS), PAL and heart rate variability (HRV) in postmenopausal women phase. Participated of study 30 subjects who answer PRETIE-Q together with analyses of MAS, PAL and HRV. Preference was large correlated with MAS (r = 0.63), PAL (r = 0.57) and HRVRMSSD (r = 0.52). Together, MAS (40.4%), PAL (10.7%) and HRVRMSSD (6.4%) explained 57.5% of the preference score. This results study allow to health professional, that prescribe physical exercise, understand that subjects with high aerobic capacity, cardiovagal modulation and usual PAL will have preference for high intensity exercise. In consequence, can increase the adherence to systematic practice of physical exercise. Conclude that preference of exercise intensity for women in postmenopausal phase is related with aerobic capacity, high HRV and physical activity level.

Physically active individuals look for more: An eye-tracking study of attentional bias.

Attentional capture by exercise-related stimuli is important for the regulation of physical activity. Attentional processing underlying this capture has been investigated with indirect behavioral measures based on reaction times. To investigate more direct measures of visual spatial attention toward physical activity (vs. inactivity) stimuli, we used eye-tracking and a visual dot probe task in 77 young adults with various level of physical activity. Reaction times to detect a dot appearing in the area previously occupied by a physical activity (vs. inactivity) stimulus were an indirect measure of attentional bias. The first picture gaze and viewing time were more direct measures of attentional orienting and attentional engagement, respectively. Pupil dilation was an indicator of arousal. Reaction times revealed a two-way interaction between the location of the dot and participants' usual level of physical activity. Only participants with a high level of physical activity more quickly detected a dot when it appeared in the area previously occupied by a physical activity stimulus. Eye-tracking results showed greater odds of first gazing at physical activity stimuli and for a longer time, and a greater decrease in pupil size when viewing physical activity stimuli when usual level of physical activity was moderate or high, but not low. The variance explained in the outcomes ranged from 13.9% (pupil dilation) to 40% (reaction times). Overall, as hypothesized, compared to less physically active participants, participants who were more physically active demonstrated indirect (reaction times) and direct (first gaze, viewing time) evidence of a more pronounced attentional bias toward physical activity. Physical activity stimuli biased attention, with a pronounced effect when the level of physical activity was higher. These findings suggest that physical activity stimuli are relevant to the current concerns of moderately and highly active individuals.

Effects of progressive aquatic resistance training on symptoms and quality of life in women with knee osteoarthritis: A secondary analysis.

To conduct a secondary analysis to study the effects, those 4months of aquatic resistance training have on self-assessed symptoms and quality of life in post-menopausal women with mild knee osteoarthritis (OA), after the intervention and after a 12-month follow-up period. A total of 87 post-menopausal volunteer women, aged 60-68years, with mild knee OA were recruited in a randomized, controlled, 4-month aquatic training trial (RCT) and randomly assigned to an intervention (n=43) and a control (n=44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 4months while the control group maintained their usual level of physical activity. Additionally, 77 participants completed the 12-month post-intervention follow-up period. Self-assessed symptoms were estimated using the OA-specific Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Health-related Quality of life (HRQoL) using the generic Short-form Health Survey (SF-36). After 4months of aquatic resistance training, there was a significant decrease in the stiffness dimension of WOMAC -8.5mm (95% CI=-14.9 to -2.0, P=.006) in the training group compared to the controls. After the cessation of the training, this benefit was no longer observed during the 12-month follow-up. No between-group differences were observed in any of the SF-36 dimensions. The results of this study show that participation in an intensive aquatic resistance training program did not have any short- or long-term impact on pain and physical function or quality of life in women with mild knee OA. However, a small short-term decrease in knee stiffness was observed.

Optimization of the management of a patient with a backache (with clinical observation)

Back pain in terms of socio-economic losses over the past 5 years has come to the first place among the causes of disability, and therefore the problem of rapid effective anesthesia and rehabilitation of this large group of patients is topical. In most cases, the main sources of back pain are the structures of the musculoskeletal system, and the reasons are their microtraumatization due to sudden unprepared movements, prolonged stay in a static position, heavy physical labor. The task of clinical and instrumental examination is to exclude specific causes of dorsalgia. It is also important to present the results of the survey in an accessible form, in particular to correctly interpret the data from neuroimaging research methods. Adequate anaesthesia for acute back pain, informing the patient about the favorable prognosis of the disease and early motor activation are essential to prevent the transition of the physiological feeling of pain into the pathological process - chronic pain syndrome. When dealing with chronic pain, the interaction of specialists of different profiles in the multidisciplinary team is required. Kinesiotherapy, ergotherapy, cognitive-behavioural therapy are the main methods of non-drug treatment of lower back painIt is recommended that the patient maintains the usual level of physical activity and then increases it. It is necessary to teach the patient to correctly perform movements in the social, professional and domestic spheres, to explain how to avoid unsafe movements that can provoke dorsalgia. The article presents the observation of a patient with chronic back pain. Success in treatment has been achieved through effective anesthesia through rational selection of non-steroidal anti-inflammatory drugs (Dexalgin), local administration of local anesthetics to overcome kinesiophobia, and a combination of cognitive-behavioural therapy, kinesiotherapy, and ergotherapy.
