Physiological Profiles

LANGUAGE NOTE | Document text in English; abstract also in Chinese. A proper and systematic use of physical training can enhance physiological improvement. The present study was aimed to investigate the effects of formal training programs on different physical and physiological profiles of prepubescent tribal boys at different age group. The study was conducted on 69 young boys who were divided into three subgroups i.e. Group-I (n=23, age=9.3±0.19), Group-II (n=18, age=10.1±0.86), Group-III (n=28, age=11±0.22) according to their chronological age. All the boys were inducted in Tripura sports school having formal training of 18 months. Another 64 boys were also chosen as control group (sedentary in nature) from the same community. They were also divided into three subgroups as per their respective test groups. All the boys including sedentary groups belong to similar socio-economic status and dietary habits. Tests were conducted three times in 18 months duration on test groups and twice in control groups to evaluate the height, weight, hand grip strength, body fat%, endurance ability, speed ability, explosive power of the lower extremities and hemoglobin% of all the boys. The result of the present study revealed that almost all the parameters were increased significantly in all three test groups after 18 months duration, except body fat% which was found to be changes insignificantly in group II boys. When the comparison was made among the groups, it was observed that in pre training, all the parameters were changed significantly at p<0.01 & body fat% at p<0.05 level except 800m run and standing broad jump (SBJ) respectively. Significant differences were also observed following 18 months of training in height, hemoglobin percent, 800m run at the level of p< 0.05 and weight, hand grip strength, 30m flying start, aerobic capacity, SBJ at p<0.01 levels, except body fat% which was found to be statistically insignificant. All the parameters were found to be more in Test group-III as compared to other two groups. Prior to training no such significant differences were observed in above parameters with respect to control group. Following 18 months of training, a significant difference was found with respect to control group in all parameters except height, weight (Gr-I & Gr- II) & body fat%. However the increase in above anthropometric and physiological parameters may only because of the augmenting effect of training or due merely because of their growth & development. It has been reported that moderate physical training is necessary for normal growth & development and it is more pronounced in the subject who belongs at the trigger point of adolescence. So it may be concluded that under same nutritional status the effect of formal training is more effective in higher age group as compared to the lower age group. 本文旨在探討印度部落兒童，透過運動訓練而影響的體型及生理變化。邀請了69名兒童進行評估及比較，結果顯示: 大部份體型及生理指標有明顯的增長。

AbstractThis paper describes a 4-month pilot study that tested the suitability of a physical activity intervention for first graders (children aged 6 and 7 years) in a public school in Santiago, Chile. Teachers were trained to deliver the programme in the classroom during the school day. Teachers were surveyed to determine if this intervention fit within their curriculum and classroom routines and they reported in a focus group that it was suitable for them. All children actively participated in the programme and positive changes in their attitudes towards physical activity were observed by their teachers. Anthropometrics, blood pressure and hand grip strength were measured in the students. A significant reduction was observed in children with high waist circumference ≥ 90th percentile, and in mean systolic blood pressure. However, statistical power values for those comparisons were rather low. Anthropometry and hand grip strength were not modified. The latter calculations and the lack of a control group are showing the weaknesses of this pilot study and that further research with a larger sample size and an experimental design is strongly needed.

IntroductionAge-related loss of muscle mass, muscle strength and muscle function (sarcopenia) leads to a decline in physical performance, loss of independence and reduced quality of life. Nutritional supplements may delay the progression of sarcopenia. The aim of this randomised, double-blinded controlled trial including 100 participants (≥65 years) is to assess the effect of a marine protein hydrolysate (MPH) on sarcopenia-related outcomes like hand grip strength, physical performance or gait speed and to study the associations between physical performance and nutritional intake and status.Method and analysisThe intervention group (n=50) will receive 3 g of MPH per day in 12 months. The control group (n=50) receive placebo. Assessments of Short Physical Performance Battery (SPPB), hand grip strength, anthropometric measurements, nutritional status as measured by the Mini Nutritional Assessment, dietary intake, supplement use, biomarkers of protein nutrition and vitamin D, and health-related quality of life (EQ-5D), will be performed at baseline and after 6 and 12 months of intervention. Linear mixed models will be estimated to assess the effect of MPH on SPPB, hand grip strength and quality of life, as well as associations between physical performance and nutrition.Ethics and disseminationThe study has been approved by the Regional Committee in Ethics in Medical Research in Mid-Norway in September 2016 with the registration ID 2016/1152. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media and print media.Trial registration numberNCT02890290.

Background Anxiety disorders are leading contributors to the global disease burden, highly prevalent across the lifespan and associated with substantially increased morbidity and early mortality. Aims The aim of this study was to examine age-related changes across a wide range of physiological measures in middle-aged and older adults with a lifetime history of anxiety disorders compared with healthy controls. Method The UK Biobank study recruited >500 000 adults, aged 37–73, between 2006 and 2010. We used generalised additive models to estimate non-linear associations between age and hand-grip strength, cardiovascular function, body composition, lung function and heel bone mineral density in a case group and in a control group. Results The main data-set included 332 078 adults (mean age 56.37 years; 52.65% women). In both genders, individuals with anxiety disorders had a lower hand-grip strength and lower blood pressure, whereas their pulse rate and body composition measures were higher than in the healthy control group. Case–control group differences were larger when considering individuals with chronic and/or severe anxiety disorders, and differences in body composition were modulated by depression comorbidity status. Differences in age-related physiological changes between females in the anxiety disorder case group and healthy controls were most evident for blood pressure, pulse rate and body composition, whereas this was the case in males for hand-grip strength, blood pressure and body composition. Most differences in physiological measures between the case and control groups decreased with increasing age. Conclusions Findings in individuals with a lifetime history of anxiety disorders differed from a healthy control group across multiple physiological measures, with some evidence of case–control group differences by age. The differences observed varied by chronicity/severity and depression comorbidity.

Whole Body Vibration (WBV) is a type of exercise commonly applied as a modern exercise technique. The purpose of the present study was to examine the effects of WBV applied for 10-week on strength, flexibility and agility in taekwondo athletes. A total of 23 healthy young males participated in the present study. The athletes were separated randomly into two groups as the control group (n=11) and whole body vibration training group (n=12). The WBV training group did training 3 days a week for 10 weeks. The Control Group did not do any trainings. The hand grip strength test, vertical jump test, sit-reach test, agility t-test were applied to the WBV training group and control group before and after the 10-week WBV training. The comparisons between the groups were analyzed by using an independent sample t-test at a significance level of p&lt;0.05. No statistically significant differences were detected between the pre-test hand grip strength, vertical jump test, sit-reach test and agility t-test results of the WBV training group and control group according to the Independent sample t test. In the post-test results, statistically significant differences were detected between the vertical jump test, sit-reach test, agility t-test however, no statistically significant differences were detected between the hand grip strength results. The intra-group comparisons were made according to the paired sample t test at a significance level of p&lt;0.05. Although statistically significant differences were detected in the WBV training group between the pre-test-post-test, vertical jump test, sit-reach test, agility t-test values, no statistically significant differences were detected between the hand grip strength results. No statistically significant differences were detected between the hand grip strength, vertical jump, sit-reach, agility t-test pre-test and post-test results of the control group. Long-term whole body vibration training has positive strength, flexibility and agility values.

The functional preference for the upper limb influences the occurrence of bilateral differences in other segments of the human body. The aim of the study is to assess the influence of the applied fighting technique and targeted physical effort on the occurrence of asymmetry in body musculature and isometric strength in bodybuilders and competitors of selected martial arts. Academic athletes practicing judo (J), jiu-jitsu (JJ), and bodybuilding (BB) were examined. The control group (C) consisted of students who do not practice any sports. The assessment of the body structure was conducted through segmental bioelectrical impedance analysis. Moreover, the study took into account the measurements of left- and right-hand grip strength. In judo, the uneven physical exertion of the right and left sides of the body further increases both directional and absolute asymmetry. Bilateral asymmetry of musculature in jiu-jitsu competitors and bodybuilders occurs to a lesser extent. The control group was characterized by cross-asymmetry. So as to avoid the risk of injury of sportsmen, it is important to consistently supervise and correct their body structure, which also includes the symmetrical participation of the active muscle mass in particular segments. The symmetrisation process should be individualized since each particular sportsman has their own side-to-side body morphology.

Objective: To evaluate the effects of an intervention based on a specific set of goals on goal attainment, manual dexterity, hand grip strength and finger prehension force compared to a standardized approach in patients with Parkinson’s disease. Design: Randomized controlled trial. Setting: Home-based. Participants: Fifty patients with a clinical diagnosis of Parkinson’s disease acknowledging impaired manual ability were randomized into two groups. Interventions: Patients in the experimental group ( n = 25) were included in an intervention focused on task components that involved goals proposed by participants. Patients in the control group ( n = 25) received a standard intervention focused on impairments in range of motion, grasp and manipulation. Home condition and duration (four weeks, twice a week) were similar in both groups. Main outcome measures: The primary outcome measure was goal achievement assessed with the Goal Attainment Scaling. Secondary outcomes were manual dexterity evaluated with the Purdue Pegboard Test and hand grip strength and finger prehension force assessed using a dynamometer. Results: After four weeks, significant between-group improvement in goal attainment was observed in the experimental group (change 17.36 ± 7.48 vs. 4.03 ± 6.43, P < 0.001). Compared to the control group, the experimental group also showed a significant improvement ( P < 0.05) in manual dexterity (postintervention values in the most affected arm 10.55 ± 1.95 vs. 7.33 ± 3.63 pins, P < 0.001) and finger prehension force (postintervention values in the most affected arm 8.03 ± 1.93 vs. 6.31 ± 1.85 kg, P = 0.010). Conclusions: Targeting therapy toward specific goals leads to greater changes in arm function than a standardized approach in people with Parkinson’s disease.

SummaryMales and females differ in their preference for occupations and sporting activities, and differ also in risk-taking attitudes. In addition to other explanations, prenatal hormone exposure has been implicated in these gender-associated differences. The ratio of the relative lengths of the second-to-fourth digits (2D:4D) is a proxy indicator of prenatal exposure to testosterone relative to oestrogen. The 2D:4D ratio has been found to be associated with choice of occupation, particularly among females. This study investigated whether 2D:4D differed between police officers and a control group of civilians in Wrocław, Poland. Participants were 147 male and 55 female police officers and 91 male and 75 female civilian controls. The police officers had to undergo rigorous physical ability tests during recruitment and their job bore relatively higher risk, whereas the controls had a normal civilian lifestyle. Height, weight, hand grip strength and lengths of the second and fourth digits were measured. Analyses of variance and covariance were employed to assess the significance of difference in digit ratio between groups (police officers and civilians) allowing for interaction with sex. The policewomen, compared with the female controls, were taller and had stronger hand grip strength, but had lower 2D:4D in the right hand and average 2D:4D of both hands. However, male and female police officers slightly differed only in the right hand digit ratio but not in the left hand ratio or the average for the two hands. However, the control group showed significant sex differences in all digit ratios with higher (feminine) mean values in females. The study provides further evidence that prenatal testosterone exposure, as reflected in the 2D:4D ratio, might have an association with choice of occupation, particularly among females.

The purpose of this study was to investigate the effects of 6-week exercises performed by elastic resistance band on functional performance (balance, agility, hand grip strength and flexibility) in children aged 8-9 years. So, 102 students participated in this study according to pre-test and post-test design. Participants were divided into two groups: experimental group (n=50, height: 134.0 ± 6.3 cm, mass: 30.9 ± 7.9 kg, age: 8.6 ± 0.5 years) and control group (n=52, height: 135.0 ± 6.2 cm, mass: 32.4 ± 5.9 kg, age: 8.6 ± 0.6 years). The experimental group performed exercises using elastic resistance bands of lightness grade at the same time of day (45 minutes/day, 3 days/week), and the control group did not participate in any physical activity. Balance was measured by Flamingo Test, agility by Ilinois, flexibility by sit and reach box and strength was measured by hand-grip dynamometer. It was determined that 6-week exercises performed by elastic resistance band increased significantly the hand grip strength; however there was no statistically significant effect on balance, agility and flexibility abilities.The inclusion of elastic resistance band exercises in the context of school activity programs can improve children's strengths. For this reason, exercises performed by elastic resistance bands for more than 6 weeks can be added to activity programs in school as an economical, fun and reliable way to improve the hand-grip performance of children.

Abstract BackgroundThere has been a growing interest in the role of vitamin D for the well-being and physical performance of humans; however, there is a lack of long-term supplementation studies performed on members of the young, physically active, male population.The hypothesis of the study was that vitamin D supplementation during wintertime will decrease the prevalence of critically low vitamin D blood serum levels and increase hand grip strength during the winter season among young male conscripts. Study DesignLongitudinal, triple-blinded, randomized, placebo-controlled trial. MethodsFifty-three male conscripts from the Estonian Army were randomized into two groups: 27 to an intervention group and 26 to a placebo group. The groups were comparable in terms of their demographics. The intervention group received 1200 IU (30 µg) capsules of vitamin D3 and the control group received placebo oil capsules once per day. The length of the follow-up was seven months, from October 2016 until April 2017. Blood serum vitamin D (25(OH)D), parathyroid hormone (PTH), calcium (Ca), ionized calcium (Ca-i), testosterone and cortisol values and hand grip strength were measured four times during the study period. ResultsThe mean 25(OH)D level decreased significantly in the control group to a critically low level during the study, with the lowest mean value of 22 nmol/l found in March 2017. At that time point, 65% in the control group vs 15% in the intervention group had 25(OH)D values of less than 25 nmol/l (p < 0.001). In the intervention group the levels of 25(OH)D did not change significantly during the study period. All other blood tests revealed no significant differences at any time point. The corresponding result was found for hand grip strength at all time points. ConclusionLong-term vitamin D supplementation during wintertime results in fewer conscripts in the Estonian Army with critically low serum vitamin D (25(OH)D) levels during the winter season. However, this did not influence their physical performance in the form of the hand grip strength test. Trial registrationClinicalTrials.gov Identifier: NCT04359524.
