Test–retest reliability of pivoting proprioception assessment and its association with physical activity in healthy young adults

The Physical Activity Guidelines for Americans recommend a minimum of 150 min of moderate-to-very vigorous exercise per week for adults. Meeting these requirements is associated with long-term increases in functional capacity and brain health, as well as decreases in cardiovascular disease risk and all-cause mortality. However, whether or not daily physical activity levels acutely impact vascular function are unknown. PURPOSE: To determine the relation between daily physical activity and nitric oxide-mediated microvascular function in young healthy adults. Using the skin as a model circulation, we hypothesized greater physical activity would be positively related to nitric oxide (NO)-mediated microvascular function. METHODS: 20 young (25 ± 5 years) healthy (BMI: 24 ± 3 kg/m2; SBP: 112 ± 10 mmHg; DBP: 71 ± 6 mmHg; HDL: 56 ± 8 mg/dL; LDL: 88 ± 23mh/dL; HbA1c: 4.7 ± 0.3%) adults (11 W/9 M) wore an accelerometer around their waist while awake for 7 days. A minimum of 4 wear days for ≥10 hours/day were required for inclusion in these analyses. On day 8, microvascular physiology was assessed with a standardized 39 °C local heating protocol to quantify NO-dependent vasodilation through the perfusion of 15 mM NG-nitro-l-arginine methyl ester during the plateau of the heating response. Red blood cell flux was measured (laser-Doppler flowmetry) and cutaneous vascular conductance (CVC = flux/mmHg) was calculated and expressed as a percentage of maximum (%CVCmax; 28 mM sodium nitroprusside +43 °C). RESULTS: The local heating plateau (64 ± 21 %CVCmax) and NO-dependent vasodilation (68 ± 8%) were not related to percent time spent in sedentary (68 ± 7%; R2 = 0.01, p = 0.63; R2 = 0.06, p = 0.30), light (57 ± 7%; R2 = 0.03, p = 0.49; R2 = 0.06, p = 0.30), or moderate-to-very vigorous (6 ± 4%; R2 = 0.06, p = 0.35; R2 < 0.01, p = 0.80) physical activity. The local heating plateau and NO-dependent vasodilation were also not correlated with average steps per day (8111 ± 3374 steps; R2 < 0.01, p = 0.72; R2 < 0.01, p = 0.97). CONCLUSION: Daily physical activity was not related to cutaneous NO-mediated microvascular physiology in young healthy adults. These results indicate that the microvascular physiology in healthy young adults is unrelated to physical activity or sedentary behavior, likely due to robust redundant mechanisms underlying their vascular function.

Event Abstract Back to Event Prefrontal Cortex Activity during Dual Task Performance: A Functional Neuroimaging Study Syed A. Hassan1*, Leandro V. Bonetti2, Kara K. Patterson3, Deryk S. Beal4, Anthony C. Ruocco5 and Darlene Reid3 1 University of Toronto, Rehabilitation Sciences Institute, Department of Physical Therapy, Canada 2 University of Caxias do Sul, Department of Physical Therapy, Brazil 3 University of Toronto, Department of Physical Therapy, Canada 4 University of Toronto, Department of Speech-Language Pathology, Canada 5 University of Toronto, Department of Psychology, Canada BACKGROUND. Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death and had an associated healthcare burden of $50 billion USD in 2010 (Guarascio, Ray, Finch, & Self, 2013). Alterations in the prefrontal cortex (PFC), involved in attentional control, planning and decision making, may in part explain the cognitive impairment and motor deficits (e.g., impaired balance and slower walking speed) in COPD patients. Functional near infrared spectroscopy (fNIRS) is a novel imaging technique that can quantify cortical neural activity via oxy-hemoglobin (O2Hb) and provide insight into the link between central processing and motor performance. OBJECTIVE. To compare relative changes in the PFC O2Hb, accuracy of backwards spelling, and decrements in gait during single and dual tasks in patients with COPD, and healthy young and old adults. HYPOTHESES. H1: PFC O2Hb will increase during backwards spelling compared to the baseline task and increase even more during dual tasks compared to single tasks in patients with COPD, and healthy old and young adults. H2: Compared to single tasks, participants in all three groups will have a decrease in accuracy of backwards spelling and greater decrements in gait during dual tasks. METHODS. All participants performed the following single tasks: (1) backwards spelling as the cognitive task (CT); (2) 30m preferred paced walk (PPW); and (3) 30m fast paced walk (FPW). The dual tasks then paired CT with each of PPW and FPW. The fNIRS data was processed in fnirSoft to attenuate physiological noise (e.g. heart rate) and motion artifacts. Changes in the left dorsolateral PFC O2Hb were then calculated using the modified Beer-Lambert law. Gait parameters (e.g. velocity) were measured using a 5x0.88m pressure sensitive Zeno mat (contains 13,824 pressure sensors). RESULTS. Twenty young healthy adults (10M:10F) with a mean age of 28±4 years, twenty old healthy adults (10M:10F) with a mean age of 64±11 years and six adults with COPD (3M:3F) with a mean age of 74±8 years participated. The PFC ∆O2Hb increased during the CT compared to the baseline task in the healthy young individuals (p=0.042) and tended to be greater in healthy old adults and COPD patients. Similarly, it was significantly higher in the old adults during the FPW+CT compared to FPW (0.27±0.95µM vs. -0.49±1.01µM, p=0.007) as well as during PPW+CT compared to PPW (0.20±0.77µM vs. -0.35±0.84µM, p=0.019). In addition, PFC ∆O2Hb tended to be higher during FPW+CT compared to FPW in healthy young adults (-0.04±0.97µM vs. -0.36±1.09µM) and COPD patients (0.13±1.09µM vs. 0.07±0.85µM). When comparing single tasks to dual tasks, the accuracy of the backwards spelling decreased significantly in the young healthy (-16.9±21.4%, p=0.002) and old healthy group (-20.1±22.2%, p=0.001) and tended to decrease in the COPD group (-32.2±45.7%, p=0.191) during performance of FPW+CT compared to CT alone. Similarly, participants exhibited decrements in gait during dual tasks compared to single tasks: (1) velocity during FPW+CT decreased in all three groups compared to FPW alone (Figure 1); (2) velocity during PPW+CT decreased in older adults compared to PPW alone (Figure 1); (3) swing time variability also increased in old adults and COPD patients during FPW+CT compared to FPW alone (p=0.030 and p=0.038, respectively); and (4) stance time variability of COPD patients increased during FPW+CT compared to FPW (p=0.026) and of young and old healthy adults during PPW+CT compared to PPW (p=0.027 and p=0.015, respectively). CONCLUSIONS. Our results demonstrate that dual tasks compared to single tasks increased more PFC ∆O2Hb, decreased accuracy of spelling backwards and resulted in slower and more variable gait. A larger sample of COPD patients would refine the strength of our data. Figure 1 References Guarascio, A. J., Ray, S. M., Finch, C. K., & Self, T. H. (2013).

Regular physical activity (PA) is an important part of the treatment of several medical conditions, including overweight and obesity, in which there may be a weakened appetite control. Eating behaviour traits influence weight control and may be different in active and sedentary subjects. This paper reports the relationships between the time spent in sedentary behaviour and physical activity (PA) of different intensity, and eating behaviour traits in young, healthy adults. Additionally, it reports the results of a six-month-long, randomized, controlled trial to examine the effect of an exercise intervention on eating behaviour traits. A total of 139 young (22.06 ± 2.26 years) healthy adults (68.35% women) with a Body Mass Index (BMI) of 24.95 ± 4.57 kg/m2 were enrolled. Baseline assessments of habitual PA were made using wrist-worn triaxial accelerometers; eating behaviour traits were examined via the self-reported questionnaires: Binge Eating, Three-Factor Eating Questionnaire-R18 and Control of Eating Questionnaire. The subjects were then randomly assigned to one of three groups: control (usual lifestyle), moderate-intensity exercise (aerobic and resistance training 3¨C4 days/week at a heart rate equivalent to 60% of the heart rate reserve (HRres) for the aerobic component, and at 50% of the 1 repetition maximum (RM) for the resistance component), or vigorous-intensity exercise (the same training but at 80% HRres for half of the aerobic training, and 70% RM for the resistance training). At baseline, sedentary behaviour was inversely associated with binge eating (r = −0.181, p < 0.05) and with uncontrolled eating (r = −0.286, p = 0.001). Moderate PA (MPA) was inversely associated with craving control (r = −0.188, p < 0.05). Moderate-to-vigorous PA (MVPA) was directly associated with binge eating (r = 0.302, p < 0.001) and uncontrolled eating (r = 0.346, p < 0.001), and inversely associated with craving control (r = −0.170, p < 0.015). Overall, PA was directly associated with binge eating (r = 0.275, p = 0.001), uncontrolled eating (r = 0.321, p < 0.001) and emotional eating (r = 0.204, p < 0.05). Additionally, only emotional eating was modified by the intervention, increasing in the vigorous-intensity exercise group (p < 0.05). In summary, we observed that time spent in sedentary behaviour/PA of different intensity is associated with eating behaviour traits, especially binge eating in young adults. In contrast, the six-month exercise intervention did not lead to appreciable changes in eating behaviour traits.

The role of individual physical body measurements and activity on spine kinematics during flexion, lateral bending and twist tasks in healthy young adults – Comparing marker(less) data

Purpose: This study investigated the relationship between estimated oxygen consumption (VO2max) and handgrip strength (HGS) among healthy young Nigerian adults. Methods: This was a cross sectional study, which involved 400 volunteers (171 males; 229 females) aged between 18–40years. Participants’ HGS was assessed using a CAMRY EH-101 hand dynamometer while VO2max was estimated using a standard formula that includes measurement of resting heart rate. Demographic data was summarized using percentages, mean and standard deviation. Physical activity level of the participants was assessed using long form of the International Physical Activity Questionnaire. Independent t-test was used to compare the mean values of the variables between male and female participants. Pearson’s correlation was used to determine the strength of relationship between estimated VO2max and HGS, while multiple regression analysis was conducted to determine the predictors of estimated VO2max using HGS as well as body mass index (BMI), physical activity (PA) level, age and sex as co‐variates. Level of significance was set at p&lt;0.05. Results: HGS, VO2max and PA level were significantly (p= 0.001) different between male and female participants. There was a significant moderate correlation between HGS and VO2max (r= 0.40, p= 0.001). The results of the regression analysis showed that HGS is not significant predictor of estimated VO2max; whereas, sex, BMI and PA level were significant predictors of estimated VO2max. Conclusion: Although HGS is moderately correlated with estimated VO2max, HGS may not be a relevant tool for predicting estimated VO2max in healthy young adults.

Triacylglycerols and body fat mass are possible independent predictors of C3 in apparently healthy young Brazilian adults

CONTEXT: Physical activity (PA) is postulated to predict fitness components, especially cardiovascular endurance. But its relationship with agility remains largely unknown. AIMS: The aim of the study is to find the degree of relationship between PA volume and agility in healthy young adults. SETTINGS AND DESIGN: This cross-sectional study was conducted in a physiotherapy department of a physiotherapy college in South India. SUBJECTS AND METHODS: Sixty young adults were recruited and assessed for PA and agility levels through International PA Questionnaire and Illinois test, respectively, after obtaining the informed consent. STATISTICAL ANALYSIS USED: The relation between PA and agility was assessed by Spearman's rank correlation test. RESULTS: Majority of the participants (53.33%) accumulated moderate PA. The mainstream of the participants (81.67%) showed poor agility. Our findings did not show a significant difference (r = 0.12, P = 0.361) between PA and agility among the young adults. CONCLUSIONS: PA may not be a crucial determinant for the agility component of fitness in young adults.

Background/Objectives: The Physical Activity and Social Support Scale (PASSS) is used to evaluate the physical activity and social support in a multidimensional way, but it has not yet been translated or culturally adapted for Turkish-speaking individuals. The aim of this study is to evaluate the validity and reliability of the Turkish version of the PASSS, which evaluates social support for physically active, healthy young adults. Methods: Two hundred and two individuals (98 females, 104 males; mean ± SD age, 26.5 ± 6.1 years; BMI, 23.3 ± 3.2 kg/m2) participated in the study. The PASSS was translated into Turkish using the Beaton guidelines. Multidimensional Scale of Perceived Social Support (MSPSS), International Physical Activity Questionnaire-Short Form (IPAQ-SF), and Short Form-12 Health Survey (SF-12) were used for construct, convergent, and divergent validity. Results: The PASSS demonstrated good internal consistency (Cronbach's α = 0.84) and excellent reliability (ICC = 0.90; 95% CI = 0.86-0.93). The PASSS showed good correlation with the MSPSS (r = 0.378, p = 0.001), fair correlation with the IPAQ-SF (r = 0.271, p = 0.001), and poor correlation with the SF-12 physical component score (PCS-12) (r = 0.15, p = 0.03); it was not correlated with the SF-12 mental component score (MCS-12) (r = 0.102 p = 0.15). We observed no ceiling and floor effects. Conclusions: The results show that the PASSS Turkish version is reliable and valid and can be utilized for physically active, healthy young Turkish adults.

BackgroundMultiple sclerosis (MS) is the most common chronic autoimmune demyelinating and inflammatory disease of the central nervous system, afflicting both the body and mind. The risk of suffering from MS is 2.5–3.5 times greater in females than in males. While there is extant research on fatigue, depression, and cognitive impairment in patients with MS during its clinical course, there is a lack of research focusing on sleep, psychological functioning, and physical activity (PA) at the point of disease onset. The aims of the present study were therefore, to assess the markers of mental toughness (MT) as a dimension of psychological functioning, sleep disturbances (SD), and PA among patients at the moment of disease onset and to compare these with the corresponding values for healthy adolescents and young adults.MethodsA total of 23 patients with MS at disease onset (mean age =32.31 years; 91% females), 23 healthy adolescents (mean age =17.43 years; 82% females), and 25 healthy young adults (mean age =20.72 years; 80% females) took part in the study. They completed questionnaires covering sociodemographic data, MT, SD, and PA.ResultsPatients with MS had similar scores for MT traits as those in healthy adolescents and healthy young adults, and equivalent levels of moderate-intensity PA and SD as young adults. MS patients reported lower levels of vigorous PA compared to both healthy adolescents and young adults.ConclusionThe pattern of the results of the present study suggests that the onset of MS is not associated with poor MT, poor sleep, or reduced moderate-intensity PA. Lower levels of vigorous PA were observed in MS patients. Low levels of vigorous PA may lead to decreased cardiorespiratory fitness in patients with MS and, in the long run, to reduced cardiovascular health and degraded psychological functioning.

BackgroundA healthy diet has been proposed to support good mental health, but the addition of either red meat or meat alternatives is nuanced. ObjectivesWe aimed to determine if psychological and physiological well-being is differentially affected by consuming recommended weekly amounts of either lean red meat or plant-based meat alternatives (PBMAs) supplemented with a plant-rich diet. MethodsThe trial was a parallel 2-arm randomized intervention of 10 wk duration. Eighty healthy omnivorous young adults were clustered as 40 cohabitating household pairs. Each pair was randomly assigned to consume 3 weekly servings of either fresh New Zealand beef and lamb or the equivalent PBMA. They maintained an otherwise ovo-lacto vegetarian diet, aided by a weekly meal kit and supported by engaged advice from research dietitians. Psychological measures were well-being (World Health Organization–Five Well-Being Index); depression, anxiety, and stress (depression anxiety stress scales-short form-21); and fatigue (multidimensional fatigue symptom inventory-short form) assessed weekly throughout the trial. Blood biomarkers included neurotransmitter-related compounds, iron status and vitamins B12 and D. Physical activity and sleep were estimated by a fitness wristband. Mixed effect modeling evaluated changes in each outcome over time relative to its baseline and compared the 2 interventions accounting for randomization unit clustering. ResultsThirty-nine household pairs completed the trial. Participants measured as psychologically healthy at baseline. There were no significant differences between groups in the degree of change from baseline for the psychological outcomes, nor for the majority of the circulatory markers. Differences in changes to vitamin B12 status and 3 neurotransmitter-related compounds (adenosine, agmatine, and tyrosine) from baseline to week 10 were observed between groups. Results were similar in all sensitivity analyses when adjusting for physical activity, sleep, and diet quality covariates. ConclusionsThere was no effect on the psychological measures and limited change to physiological status when comparing a balanced diet containing either red meat or PBMAs in healthy young adults.

Purpose/Hypothesis: The purpose of this study was to characterize differences in the time required to adaptively re-weight visual information following a sudden change in visual motion amplitude in healthy young, healthy older, and fall-prone older adults. Number of Subjects: Tree groups of subjects participated: healthy young adults (ages 20–30 yrs, N=21), healthy older adults (ages 70–93 yrs, N=25), and fall-prone elderly (ages 73–92 yrs, N=17). Materials/Methods: Subjects were exposed to two visual motion conditions in which the amplitude of visual motion stimuli switched from low-to-high or high-to-low. The postural sway responses to this change in visual environment were analyzed (COM gain, phase, position variability and velocity variability). We compared absolute levels of COM gain at, and adaptive gain changes across, selected time intervals and between groups. Changes in gain over time were analyzed using non-linear regression to obtain comparative prolonged rates of change before and after each amplitude switch, and rapid rates of change at each switch. Results: Absolute levels of gain, pre-and post-switch, were consistently higher in both older adult groups than in the young, when the stimulus amplitude was high. Gains were frequently higher in the fall-prone versus healthy older and young adults when the stimulus amplitude was low. For all three groups, adaptive sensory re-weighting was refected by gain changes following stimulus motion amplitude changes. Interestingly, all three groups showed evidence of equally rapid re-weighting at the time of the amplitude switch. Between-group differences were apparent in the prolonged changes in gain. Compared to young adults who usually did not reweight further after the initial rapid adaptation, both older adult groups demonstrated continued gradual changes in gain over time periods of 105 seconds. When the stimulus amplitude was high, both older adult groups demonstrated slower prolonged adaptation rates than the young. Rates of prolonged adaptation were not different between the older groups and the young when the stimulus amplitude was low. Conclusions: Rapid re-weighting when the stimulus amplitude suddenly increases is necessary to prevent instability. All three groups demonstrated functionally adaptive responses. However, down-weighting to high-amplitude stimuli is slower and to a lesser extent in healthy and fall-prone older adults compared to young adults. With low-amplitude stimuli, fall-prone older adults continued to have the highest absolute levels of gain and slowest rates of prolonged change compared to healthy older and young adults. Clinical Relevance: Older adults, especially the fall-prone elderly, may experience relatively heightened periods of postural instability and increased risk of falls until sensory adaptation is complete. It may be possible to increase the adaptation rate, and thus reduce the duration of periods of instability, via sensory-challenge balance exercises; future studies are needed to explore this possibility.

Research in obese individuals without co-morbidities is a need of hour. In this study estimation of lipid peroxidation products (TBARS), Total anti-oxidant capacity(TAC), Ceruloplasmin and physical activity score was assessed in obese and non-obese healthy young adults of a urban population in South India with Correlation between the said parameters, and to know whether ceruloplasmin is an oxidant or an anti-oxidant. Study was conducted in 140 healthy young adults, categorised into obese and non-obese (male and female), with BMI > 28 and < 23 respectively. SQUASH questionnaire was filled by the participants to assess their physical activity status. WHR was measured followed by biochemical analysis of TBRS, TAC and ceruloplasmin by standard methods, after Blood pressure, glucose, TSH were found to be normal. Healthy obese and non-obese, aged 22–24 yrs, with BMI, WHR, TBRS, ceruloplasmin, physical activity score increased and TAC decreased, statistically in obese when compared to non-obese. (p<0.05) reflecting inflammatory, and oxidative stress changes. Positive correlation was found between WHR, ceruloplasmin and TBRS, proving ceruloplasmin to be an oxidant, than an antioxidant. Increased physical activity may be the reason for obese yet healthy individuals.

Are accelerometer-measured sitting and physical activity times associated with muscle mass and strength in healthy young adults in the UAE?

Increased central arterial stiffness and enhanced arterial wave reflections may contribute to increased risk of cardiovascular disease development with advancing age. Omega-3 polyunsaturated fatty acid (n-3) ingestion may reduce cardiovascular risk via favorable effects exerted on arterial structure and function. We determined the effects of n-3 supplementation (4 g/day for 12 weeks) on important measures of central arterial stiffness (carotid-femoral pulse wave velocity; PWV) and arterial wave reflection (central augmentation index) in young (n = 12; 25 ± 1-year-old, mean ± SE) and older (n = 12; 66 ± 2) healthy adults. We hypothesized that n-3 supplementation would decrease carotid-femoral PWV and central augmentation index in older adults. Our results indicate that carotid-femoral PWV and central augmentation index were greater in older (988 ± 65 cm/sec and 33 ± 2%) than in young adults (656 ± 16 cm/sec and 3 ± 4%: both P < 0.05 compared to older) before the intervention (Pre). N-3 supplementation decreased carotid-femoral PWV in older (Δ-9 ± 2% Precompared to Post; P < 0.05), but not young adults (Δ2 ± 3%). Central augmentation index was unchanged by n-3 supplementation in young (3 ± 4 vs. 0 ± 4% for Pre and Post, respectively) and older adults (33 ± 2 vs. 35 ± 3%). Arterial blood pressure at rest, although increased with age, was not altered by n-3 supplementation in young or older adults. Collectively, these data indicate that 12 weeks of daily n-3 supplementation decreases an important measure of central arterial stiffness (carotid-femoral PWV) in older, but not young healthy adults. The mechanism underlying decreased central arterial stiffness with n-3 supplementation is unknown, but appears to be independent of effects on arterial blood pressure or arterial wave reflections.

Introduction: Our aim was to evaluate the changes in choroidal thickness (CT) and volume (CV) following aerobic physical exercise in healthy young adults. Methods: This study included 72 eyes from healthy volunteers between 22 and 37 years old. Using the International Physical Activity Questionnaire, total physical activity was computed. Measurements using an autorefractometer, ocular biometry, and spectral-domain optical coherence tomography using the Enhanced Depth Imaging protocol were taken. OCT was performed as a baseline measurement and after performing 10 min of dynamic physical exercise (3 and 10 min post-exercise). The choroidal layer was manually segmented, and the CT and CV in different areas from the Early Treatment Diabetic Retinopathy Study grid were obtained. Results: In healthy adults, at 3 min post-exercise, CT was higher in the subfoveal, the 3-mm nasal, and the 6-mm superior areas. Between 3 and 10 min post-exercise, the CT was reduced in all areas, and in some areas, the values were even smaller than the baseline measurements. The CV values showed changes after exercise similar to those of thickness. The total CV recovery after exercise was related to sex and physical activity level. Conclusion: Individuals with higher physical activity habits had greater CV at rest than those with lower physical activity levels. During exercise, healthy young people adjust CT and CV. At 3 min post-exercise, CT and CV increase. Women and individuals with greater physical activity levels reduce their total CV more than others during recovery.
