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<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<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.

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.

Background: Muscle weakness is a risk factor for mortality in haemodialysis (HD) patients; we wished to determine whether measuring the composition of the arm with bioimpedance was associated with arm muscle strength. Methods: We measured pinch strength (PS) and hand grip strength (HGS) in 250 adult HD patients with corresponding post-dialysis multifrequency bioelectrical assessments with segmental body analysis. Results: Mean age 64.0 ± 15.6, 66% male and 45.6% diabetic. The maximum HGS in the dominant or non-fistula arm was 18.9 ± 9.2 kg and PS 4.09 ± 1.96 kg respectively, with a correlation of r = 0.80, p < 0.001. HGS was associated with body cell mass (β 0.37, p < 0.001) and PS with appendicular muscle mass (β 0.06, p < 0.001). Both HGS and PS were independently associated with the ratio of extracellular water (ECW) to total body water (TBW); β -139.5, p = 0.024, β -44.8, p < 0.001 in the arm. The presence of an arterio-venous fistula increased the ECW/TBW ratio in the arm from 0.383 ± 0.009 to 0.390 ± 0.012, p < 0.05. Conclusion: Muscle strength measured by HGS and PS was associated with both markers of whole body and segmental body composition within the arm, particularly ECW/TBW. Bioimpedance measurements and assessment of muscle strength should be measured in the non-fistula arm.

The hands are anatomically specialized for manipulative tasks with different physical objects, where they can cope with certain loads with different forces and intensity. During various physical and sports activities, the hands produce the appropriate muscular force for gripping, which manifests as the hand grip's force. For this reason, hand grip strength (HGS) is recognized as a limiting factor in all manipulative activities performed by the cranial part of the body. The current research included a sample of 22 subjects, 16 male Body Height (BH=180.28±4.65cm); Body Weight (BW=80.05±9.96kg), Body Mass Index (BMI=24.61±2.74kg/m²) and 6 female subjects Body Height (BH=167.42±11.11cm); Body Weight (BW=64.80±10.09kg); Body Mass Index (BMI=23.02±1.57kg/m²) on the third year of study at the Faculty of Physical Education and Sports. This study aimed to determine the maximum isometric muscle force of the handgrip and differences between the same gender of students. A t-test for small samples was applied for data processing, and the relevant statistical parameters were calculated. The obtained t-test results confirmed statistically significant differences between the so-called dominant and non-dominant hands in male subjects (t=4.158; p<0.05) and female subjects (t=3.176; p<0.05). The obtained results of this research will be used for analytical and diagnostic purposes with a wide range of activities in the population of physical education and sports students (assessment of physical ability, trends, and tendencies to monitor and change abilities, influence on the implementation of certain curricula of some subjects studied at the faculty, etc.).

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。

The aim of this study was to analysis the anthropometry and fitness of the under-16 regional and school cricket players. Twenty participants were selected from the Bahawalpur regional cricket team and (n = 20) from school teams. Selected variables were height, weight, skinfolds, girths, bone lengths, breadths, 30-m race, set-ups, hand grip strength, flexibility, standing broad jump, and agility. the anthropometric and physical fitness of regional and school cricket players was compared by applying Independent t-test. The results disclosed that the regional cricket players were significantly higher in arm span, arm length, and leg lengths, shoulder, elbow and knee breadths. The regional cricketers were faster in 30 m sprints, hand grip strength, setups, flexibility, and standing broad jump than school players. It was concluded the under-16 regional players were superior in anthropometric and physical fitness because they were selected from the larger population and regular in training program than school cricketers.

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.

AbstractThe purpose of this study was to compare the effects of land- vs. aquatic based plyometric training programs on the drop jump, repeated jump performance and muscle damage. Sixty-five male students were randomly assigned to one of 3 groups: aquatic plyometric training group (APT), plyometric training group (PT) and control group (CG). Both experimental groups trained twice a week for 10 weeks performing the same number of sets and total jumps. The following variables were measured prior to, halfway through and after the training programs: creatine kinase (CK) concentration, maximal height during a drop jump from the height of 30 (DJ30) and 50 cm (DJ50), and mean height during a repeated vertical jump test (RJ). The training program resulted in a significant increase (P<0.01–0.001) in RJ, DJ30, and DJ50 for PT, whereas neither APT nor CG reached any significant improvement APT showed likely/possibly improvements on DJ30 and DJ50, respectively. Greater intra-group Effect Size in CK was found for PT when compared to APT. In conclusion, although APT seems to be a safe alternative method for reducing the stress produced on the musculoskeletal system by plyometric training, PT produced greater gains on reactive jumps performance than APT.
