Altered core and skin temperature responses to endurance exercise in heart failure patients and healthy controls

Exercise training represents a central aspect of rehabilitation of heart failure patients. Previous work on passive heating suggests impaired thermoregulatory responses in heart failure patients. However, no previous study directly examined thermoregulatory responses to an exercise bout, that is, active heating, as typically applied in rehabilitation settings in heart failure. Cross-sectional observational study to compare changes in core body temperature (Tcore) and skin temperature (Tskin) during exercise between heart failure patients and controls. Fourteen heart failure subjects (65 ± 7 years, 13:1 male:female) and 14 healthy controls (61 ± 5 years, 12:2 male:female) were included. Tcore (telemetric temperature pill) and Tskin (skin thermistors) were measured continuously during a 45-min cycle exercise at comparable relative exercise intensity. Tcore increased to a similar extent in both groups (controls 1.1 ± 0.4℃, heart failure patients 0.9 ± 0.3℃, 'time*group': p = 0.15). Tskin decreased during the initial phase of exercise in both groups, followed by an increase in Tskin in controls (1.2 ± 1.0℃), whilst Tskin remained low in HF patients (-0.3 ± 1.4℃) ('time*group': p < 0.001). Furthermore, we found that a given change in Tcore was associated with a smaller increase in Tskin in heart failure patients compared with controls. When comparing heart failure patients and controls who performed exercise at similar absolute workload, between-group differences disappeared (p-values > 0.05). Heart failure patients and controls show comparable exercise-induced increase in Tcore, whilst heart failure patients demonstrate altered Tskin responses to exercise and attenuated elevation in Tskin per increase in Tcore. These impaired thermoregulatory responses to exercise are, at least partly, explained by the lower absolute workload and lower physical fitness level in heart failure patients.

Acute vascular effects of waterpipe smoking: Importance of physical activity and fitness status

ObjectiveWhile new forms of tobacco, including waterpipe (WP) smoking, continue to gain popularity, limited literature has examined the vascular health consequences. The purpose of the current study was to examine: (i) the acute WP-induced changes in vascular function; (ii) whether acute changes in vascular function are modified by lifestyle behaviors (habitual physical activity, physical fitness). MethodsFifty three (22.7 y, 36% F, 23.4 kg/m2) otherwise healthy WP smokers were recruited. Strain-gauge plethysmography was used to measure forearm blood flow, vascular resistance, venous capacitance, and venous outflow at rest and following occlusion. Habitual physical activity was determined using the Arabic version of short-form international physical activity questionnaire, while physical fitness was assessed using the 6 min walk test and handgrip strength. Partial correlations were used to examine the relationships between post-smoking vascular function and lifestyle behaviors, controlling for pre-smoking vascular measures. Results(i) WP had a small effect on forearm post-occlusion blood flow (d = −0.19), a moderate effect on venous outflow (d = 0.30), and a moderate effect on post-occlusion vascular resistance (d = 0.32). (ii) Total habitual physical activity strongly correlated with resting blood flow (r = 0.50) and moderately with vascular resistance (r = −0.40). Handgrip strength moderately correlated with venous capacitance (r = 0.30) and post-occlusion blood flow (r = 0.30), while 6 min walked distance moderately correlated with resting venous capacitance (r = 0.30). ConclusionWaterpipe smoking is associated with immediate changes in vascular function, which are exacerbated in individuals with low habitual physical activity and physical fitness levels in young otherwise healthy individuals.

Influence of physical fitness on antioxidant activity and malondialdehyde level in healthy older adults.

The aim of this study was to investigate how physical fitness level could affect antioxidant activity and malondialdehyde (MDA) level at rest and in response to exhaustive exercise in healthy older adults. Fifty older adults (average age: 66.1 ± 3.8 years) were divided according to their physical fitness level into an unfit group (UG) (n = 15), a low fitness level group (LFG) (n = 18), and a high fitness level group (HFG) (n = 17). Fitness status was classified based on answers to a questionnaire about physical activity in the previous 12 months. Before and after an incremental cycle ergometer test to exhaustion, the following markers were assessed: superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione reductase, ascorbic acid, α-tocopherol, and MDA. At rest, SOD, GPX, and α-tocopherol activities were higher in the HFG (p < 0.05), whereas MDA level was lower in the LFG in comparison with the 2 other groups (p < 0.05). During the postexercise period, antioxidant activity increased only in the LFG and the HFG (GPX, SOD, and α-tocopherol). MDA level increased in all groups after the exercise (p < 0.05). In addition, MDA level was higher during the recovery period in the HFG as compared with the others groups. This study concluded that both low and high physical fitness levels help maintain better antioxidant defenses in older adults. However, a higher physical fitness level, rather than a lower physical fitness level, could increase lipid peroxidation.

Independent and combined association of overall physical fitness and subjective well-being with fibromyalgia severity: the al-Ándalus project.

The present study aimed: (1) to test the associations of overall physical fitness and subjective well-being with fibromyalgia severity and (2) to determine whether the combination of overall physical fitness and subjective well-being is associated with fibromyalgia severity among adult women patients. This cross-sectional study included 424 participants from Andalusia, southern Spain. Overall physical fitness and the components of subjective well-being (positive affect, negative affect and cognitive well-being), and fibromyalgia severity were assessed using the Functional Senior Physical Fitness Test Battery, the Positive and Negative Affect Schedule, the Satisfaction With Life Scale, and the Fibromyalgia Impact Questionnaire, respectively. Overall physical fitness (β = -.23), positive affect (β = -.18), negative affect (β = .26), and cognitive well-being (β = -.18) were all associated with fibromyalgia severity. The patients with the highest overall physical fitness and increased subjective well-being reported ~15 % lower fibromyalgia severity than those with the lowest fitness and poorest subjective well-being (Cohen's d > 1.0). Our results suggest that higher levels of overall physical fitness and subjective well-being are independently associated with lower fibromyalgia severity. Moreover, patients with higher overall physical fitness and increased subjective well-being (high positive affect, low negative affect, or high cognitive well-being) reported lower fibromyalgia severity than those with low levels of overall physical fitness and subjective well-being.

Exercise barriers in Korean colorectal cancer patients.

To identify barriers to exercise in Korean colorectal cancer patients and survivors, and to analyze differences in exercise barriers by age, gender, treatment status, and physical activity level. A total of 427 colorectal cancer patients and survivors from different stages and medical status completed a self-administered questionnaire that surveyed their barriers to exercise and exercise participation. The greatest perceived exercise barriers for the sampled population as a whole were fatigue, low level of physical fitness, and poor health. Those under 60-years old reported lack of time (p=0.008), whereas those over 60 reported low level of physical fitness (p=0.014) as greater exercise barriers than their counterparts. Women reported fatigue as a greater barrier than men (p<0.001). Those who were receiving treatment rated poor health (p=0.0005) and cancer-related factors as greater exercise barriers compared to those who were not receiving treatment. A multivariate model found that other demographic and medical status were not potential factors that may affect exercise participation. Further, for those who were not participating in physical activity, tendency to be physically inactive (p<0.001) and lack of exercise skill (p<0.001) were highly significant barriers, compared to those who were participating in physical activity. Also, for those who were not meeting ACSM guidelines, cancer-related exercise barriers were additionally reported (p<0.001), compared to those who were. Our study suggests that fatigue, low level of physical fitness, and poor health are most reported exercise barriers for Korean colorectal cancer survivors and there are differences in exercise barriers by age, sex, treatment status, and physical activity level. Therefore, support for cancer patients should be provided considering these variables to increase exercise participation.

CHANGES OF PSYCHOMOTOR DEVELOPMENT PARAMETERS IN 7 - 9 Y. O. CHILDREN

There has been conducted a longitutidal study of schoolchildren’s physical status and psychomotor development during three years at the beginning of each academic year with participation of same first-form schoolchildren of a secondary school in Arkhangelsk. On the whole, there have been examined 76 schoolchildren (37 boys and 39 girls) at the age 7-9 y. o. An analysis of the study results has shown heterochronia and inequality of psychomotor development of the northern children at the age 7-9 years with different levels of physical fitness, what, probably, depended on individual features of functional maturation of the brain structures. Comparative monitoring has detected better formedness of praxes in the children with a medium physical fitness level, what showed bigger maturity of the motor analyzer in comparison with the children who had a low physical fitness level.

Pathway from Central Obesity to Childhood Asthma. Physical Fitness and Sedentary Time Are Leading Factors

Available prospective studies of obesity and asthma have used only body mass index (BMI) as an indicator for adiposity; studies using detailed obesity measures are lacking, and the role of physical fitness level and sedentary time remains unexplored in the link between obesity and asthma. To compare various anthropometric measures of obesity in relation to childhood asthma, and to further characterize the interrelations among central obesity, physical fitness level, sedentary time, and asthma. The nationwide Taiwan Children Health Study followed 2,758 schoolchildren from fourth to sixth grade, annually collecting data regarding physical fitness, sedentary time, obesity measures (comprising body weight and height, abdominal and hip circumference, skin fold thickness, and body composition), asthma, and pulmonary function tests. The generalized estimating equation was used for 3 years of repeated measurements to analyze the interrelation among obesity, sedentary time, physical fitness level, and asthma; a structural equation model was used to explore the pathogenesis among these factors. Asthma incidence was analyzed during a 2-year follow-up among centrally obese and nonobese groups in baseline children without asthma. Central obesity most accurately predicts asthma. Low physical fitness levels and high screen time increase the risk of central obesity, which leads to asthma development. Obesity-related reduction in pulmonary function is a possible mechanism in the pathway from central obesity to asthma. Central obesity measures should be incorporated in childhood asthma risk predictions. Children are encouraged to increase their physical fitness levels and reduce their sedentary time to prevent central obesity-related asthma.

The predictive value of physical fitness for falls in older adults with intellectual disabilities

A high incidence of falls is seen in people with intellectual disabilities (ID), along with poor balance, strength, muscular endurance, and slow gait speed, which are well-established risk factors for falls in the general population. The aim of this study was to assess the predictive value of these physical fitness components for falls in 724 older adults with borderline to profound ID (≥ 50 years). Physical fitness was assessed at baseline and data on falls was collected at baseline and after three years. Gait speed was lowest in participants who fell three times or more at follow-up. Gait speed was the only physical fitness component that significantly predicted falls, but did not remain significant after correcting for confounders. Falls at baseline and not having Down syndrome were significant predictors for falls. Extremely low physical fitness levels of older adults with ID, possible strategies to compensate for these low levels, and the finding that falls did not increase with age may explain the limited predictive value of physical fitness found in this study.

Integrative Neuromuscular Training and Sex-Specific Fitness Performance in 7-Year-Old Children: An Exploratory Investigation

Integrative neuromuscular training (INT) has successfully enhanced physical fitness and reduced abnormal biomechanics, which appear to decrease injury rates in adolescent female athletes. If not addressed at the proper time, low levels of physical fitness and abnormal mechanics may predispose female athletes to an increased risk of musculoskeletal injuries. To evaluate sex-specific effects of INT on selected measures of health- and skill-related fitness in children during physical education (PE). Cohort study. Public primary school. Forty children (16 boys, 24 girls; age = 7.6 ± 0.3 years, height = 124.5 ± 6.4 cm, mass = 29.5 ± 7.6 kg) from 2 second-grade PE classes. The classes were randomized into the PE-plus-INT group (10 boys, 11 girls) or the control group (6 boys, 13 girls) that participated in traditional PE. The INT was performed 2 times per week during the first approximately 15 minutes of each PE class and consisted of body weight exercises. Push-up, curl-up, standing long jump, single-legged hop, single-legged balance, sit-and-reach flexibility test, shuttle run, and 0.8-km run. At baseline, the boys demonstrated higher levels of performance in most of the fitness measurements as evidenced by greater performance on the push-up, standing long jump, single-legged hop, shuttle run, and 0.8-km run (P < .05). In the evaluation of the training effects, we found intervention effects in the girls for enhanced INT-induced gains in performance relative to the control group on the curl-up, long jump, single-legged hop, and 0.8-km run (P < .05) after controlling for baseline. Boys did not demonstrate similar adaptations from the INT program (P ≥ .05). These data indicate that INT is an effective and time-efficient addition to PE for enhancing motor skills and promoting physical activity in children. Seven-year-old girls appeared to be more sensitive to the effects of INT than 7-year-old boys. Future research is warranted to confirm these effects in larger cohorts of children.

Aptidão física em crianças com provável transtorno do desenvolvimento da coordenação e índice de massa corporal normal

Changes in body mass index (BMI) due to various factors, such as a low level of physical activity, are often associated with poor physical fitness in children with probable developmental coordination disorder (pDCD). This study examined whether children with pDCD would show poorer performance in terms of physical fitness when compared with their typically developing (TD) peers. Thirty two children with pDCD and normal BMI and other 32 children with TD and normal BMI, matched by gender, age and BMI, performed the sit and reach, standing long jump, curl-up, modified pull-up and 9-min run tests. The children in the pDCD group showed lower explosive power, muscle strength and endurance, and cardiorespiratory fitness than children in the TD group. Overall, children with pDCD had lower levels of physical fitness, even with normal BMI.

The predictors of falls in adult and senior women from cities of Lower Silesia, Poland

Purposebalance disorders are considered a significant problem in the elderly as they are associated with an increased incidence of falls. In effect, they can lead to numerous injuries, disability, or even death. The aim of this study was to explore the relationships between the risk of falling and various factors (morphology, socioeconomic status, physical fitness, and physical activity level) in adult and elderly women.MethodsThe study population sample included 149 women aged 47-89 years living in the province of Lower Silesia, Poland. The women were divided into two age groups of younger (&lt;i&gt;n&lt;/i&gt; =83, x&lt;sub&gt;age&lt;/sub&gt; = 59.09 years) and older (&lt;i&gt;n&lt;/i&gt; = 66, &amp;#967&lt;sub&gt;age&lt;/sub&gt; = 70.77 years) participants. Measures included BMI, marital status, and physical activity, physical fitness, and education levels. Statistical analysis included a chi-squared &amp;#967&lt;sup&gt;2&lt;/sup&gt; test, cluster analysis, logistic regression, and correspondence analysis.ResultsBMI and physical fitness were strongly correlated with falls: the higher the bMI (overweight or obese) and the lower physical fitness, the greater the risk of falling. The remaining variables showed a weak relationship with falling.ConclusionsThe fall risk of women who are overweight or obese or with a low physical fitness level is approximately 2.5 times higher than those with normal and healthy levels of BMI and physical fitness. The presence of both risk factors increased the likelihood of falling.

Determinants of changes in physical fitness after a square-stepping exercise program in community-dwelling older Japanese females

The purpose of this study was to investigate determinants of changes in physical fitness after a fall-prevention exercise program in older females. The study subjects included 83 community-dwelling females 65 years of age or older (mean age: 70.4±4.0 years) living in Kasama City, rural Japan. All subjects participated in a fall-prevention exercise program called square-stepping exercise (SSE) conducted once a week for 11 weeks. In order to assess the physical fitness benefits of by the exercise program, we measured the results of five physical performance tests: grip strength, one leg stand, sit and reach, timed up and go and the choice-stepping reaction time. In addition, we evaluated comprehensive physical fitness scores based on the standardized total score of the five physical performance tests. The changes in the comprehensive physical fitness score between baseline and after the program was used as the dependent variable, while the baseline values of age, education, clinical history, physical activity, Lubben social network scale, geriatric depression scale, five cognitive function test result, comprehensive physical fitness score and percentage of attendance were treated as independent variables. A stepwise multiple regression analysis revealed that the change in comprehensive physical fitness score correlated significantly with the baseline values of age (β=-0.273), the five cognitive function test result (β=0.293) and comprehensive physical fitness score (β=-0.607). These results suggest that older females with a low level of physical fitness at baseline are more likely to improve their physical fitness with a period of exercise training. However, the improvements in physical fitness are lower in older females with a low level of cognitive function than in those with a high level of cognitive function.

The assessment of specific physical fitness of children aged 8 and 9 years participating in tennis classes using the Jindrich Hoehm test

Summary Study aim: The purpose of the study was to use the Jindrich Hoehm test to evaluate physical fitness in boys and girls aged 8 and 9 years participating in tennis classes. Material and methods: A total of 40 children divided into four sample groups participated in the study. The J. Hoehm test consisting of seven components was used to measure and assess the physical fitness of the research participants. This test is used in child and adolescent tennis training to assess specific physical fitness. Results: The actual data showed significant differences between 8-year-old boys and girls that were established based on the test components assessing lower extremity strength capacity and the agility assessment test. In the group of children aged 9, the differences between boys and girls emerged in the test assessing lower extremity strength capacity as well as the test component assessing the forehand and backhand footwork movement technique. Inasmuch as the test component assessing lower extremity strength capacity showed differences between 8- and 9-year-old boys, no test demonstrated statistically significant differences between 8- and 9-year-old girls. Based on the normalized data, 8-year-old girls are physically fitter than 8-year-old boys. In the group of 9-year-old children, the relation is reversed. The children participating in the study display a low level of physical fitness. Conclusion: The J. Hoehm test can be a useful tool for assessing the performance of tennis coaches.

Social and regional variations in health status and health behaviours among Swiss young adults

To provide nationwide data on health status and health behaviours among young adults in Switzerland, and to illustrate social and regional variations. Data came from the Swiss Federal Surveys of Adolescents, conducted in 2010/11. The sample consisted of 32,424 young men and 1,467 young women. We used logistic regression models to examine patterns of social inequality for three measures of health status and three measures of health behaviour. Among men, lower self-rated health, overweight and lower physical fitness levels were associated with lower educational and fewer financial resources. Patterns were similar among young women. Unfavourable self-rated health (odds ratio [OR]: men 0.83, women 0.75) and overweight (OR: men 0.84, women 0.85; p >0.05) were less common in the French- than in the German-language region. Low physical fitness was more common in the French- than in the German-language region. In both sexes, daily smoking was associated with fewer educational resources, and physical inactivity was associated with lower educational and fewer financial resources. Males from the Italian-language region were three times more likely to be physically inactive than their German-speaking counterparts (OR 2.95). Risk drinking was more widespread among males in the French- than in the German-speaking language region (OR 1.47). Striking social and moderate regional differences exist in health status and health behaviours among young Swiss males and females. The current findings offer new empirical evidence on social determinants of health in Switzerland and suggest education, material resources and regional conditions to be addressed in public health practice and in more focused future research.

Subgroups associated with lower physical fitness in older adults with ID: Results of the HA-ID study

Although physical fitness is generally very low in older adults with intellectual disabilities (ID), levels may differ across subgroups. It is important to identify which subgroups need to be targeted specifically in physical activity and fitness interventions and reference values. Physical fitness was measured with box-and-block-test, response-time-test, Berg-balance-scale, walking speed, grip strength, 30s-chair-stand, 10 m incremental-shuttle-walking test and the extended modified-back-saver-sit-and-reach-test in a large sample of older adults with ID (n=1050), and subgroups associated with lower physical fitness levels were identified applying multivariate linear regression analyses. Both fixed personal characteristics such as being older, being female, having more severe ID and having Down syndrome and modifiable or preventable factors such as physical activity levels, mobility impairments and a need of more intensive care, are independently associated with lower levels of multiple physical fitness components. This first study identifies subgroups of older adults with ID which require adapted reference values, and subgroups that need to be specifically targeted in fitness promotion programs.

Excess of weight, but not underweight, is associated with poor physical fitness in children and adolescents from Castilla-La Mancha, Spain

We estimated the prevalence of underweight, overweight and obesity of children and adolescents from Castilla-La Mancha region (Spain), applying the new International Obesity Task Force (IOTF) 2012 criteria, and analysed differences in physical fitness components in relation to weight status. The sample was 2,330 schoolchildren aged 6-17 years. We measured height and weight, calculated body mass index (BMI) and assessed physical fitness using four tests included in the EUROFIT battery. Differences in physical fitness components across BMI categories, by sex, were calculated using ANOVA models. In children aged 6-11 years, 4.9 % were underweight, 26.7 % overweight and 11.0 % obese; in adolescents aged 12-17 years, 6.4 % were underweight, 16.7 % overweight and 5.8 % obese. Overall, overweight and obesity were associated with worse physical fitness but students in the underweight category did not score worse than their normal weight counterparts on fitness tests. Childhood obesity in Spain remains a public health problem. Our results show low physical fitness levels in overweight/obese children and adolescents and low levels of handgrip strength in underweight adolescents compared with normal weight subjects. Exercise programmes must be tailored to the specific needs of the subjects according to the different weight status.

The Combined Relationship of Occupational and Leisure-Time Physical Activity With All-Cause Mortality Among Men, Accounting for Physical Fitness

The aim of this study was to assess the combined relationship of occupational physical activity and leisure-time physical activity with all-cause mortality among men, while accounting for physical fitness. The prospective Belgian Physical Fitness Study included 1,456 male workers aged 40-55 years who were free of coronary heart disease at baseline. Baseline data were collected through questionnaires and clinical examinations from 1976 to 1978. To estimate physical fitness, a submaximal graded exercise test was performed on a bicycle ergometer. Total mortality was registered during a mean follow-up period of 16.9 years. Main results were obtained through Cox proportional hazards regression analysis. A total of 145 deaths were registered during follow-up. After adjustment for confounders, a significantly increased mortality rate was observed in workers who had low levels of both physical activity types (hazard ratio = 2.07, 95% confidence interval: 1.03, 4.19) but also in workers combining high occupational physical activity and low leisure-time physical activity (hazard ratio = 2.04, 95% confidence interval: 1.07, 3.91); the latter finding was particularly pronounced among workers with a low physical fitness level. The present results confirm the existence of a complex interplay among different physical activity settings and fitness levels in predicting mortality.

Indicators of physical development and physical fitness of schoolboys of first class of secondary schools

The aim of the study is to determine the status of first class schoolboys’ physical preparation of secondary schools of Kharkiv region. Testing the level of development of physical qualities of 1674 schoolboys in grades 1-4 (829 boys and 745 girls) in the standard system of school physical education. Fixed rates in these test exercises as running 30 m, six-minute run, the slope of the torso forward from a sitting position, curl in vise on the bar, 4x9 m shuttle run, standing long jump seats. Revealed a low level of physical development and physical fitness of schoolboys (in particular dexterity). It is shown that the system of assessment of learning outcomes schoolboys need to harmonize and modernize. Determined average performance of the physical qualities of boys and girls. The revealed contradictions between control standards of physical fitness in a variety of government programs.
