In Saudi Arabia, health-related physical fitness components in girls have received far less attention than physical activity. Therefore, the aim of this study was to assess health-related physical fitness components (cardiorespiratory fitness, body fat, muscle strength, and flexibility) among adolescent schoolgirls in Madinah city, western Saudi Arabia. Thirty-six female students (mean ± standard deviation, age, 17.4 ± 1.3 years; body mass, 51.6 ± 11.1 kg; height, 154.5 ± 6.9 cm) performed a Queen’s College Step Test to estimate maximal oxygen consumption. Body fat percentage was determined using a bioelectrical impedance analyzer. Hand grip strength was measured using a hand grip dynamometer, and flexibility was determined by using the sit and reach test. The mean (±standard deviation) of estimated maximal oxygen consumption was 39.5 ± 6.3 (ml.kg.min). The mean (±standard deviation) of Body fat percentage, right-hand grip strength, left-hand grip strength, and flexibility were 31.0 ±9.0 (%), 16.5±5.5 (kg), 17.1 ±4.9 (kg), and 10.6±4.8 (cm), respectively. We conclude that multiple health-related physical fitness components—with the exception of cardiorespiratory fitness—should be targeted, particularly body composition, muscle strength, and flexibility, to enhance health status among Saudi adolescent schoolgirls in Madinah. This may be accomplished by local schools, which should offer exercise programs to improve students’ physical fitness components.

It is hypothesized that there is a correlation between the ratio of second hand finger to fourth hand finger (2D:4D) which is an indicator of prenatal testosterone and physical fitness and sportive performance The aim of this study was to determined correlation between the right hand finger ratio (2D:4D) and the parameters of anthropometric and physical fitness in male and female children aged between 10 and 12. Six hundred and seventy eight males whose age average was 0.49±1.32 and 592 females whose age average was 10.38 ± 1.48 participated in this study. In addition to taking the students’ right hand 2D:4D, height, weight, triceps, subscapular, full arm and leg measurements, vertical jumping, standing long jump, flexibility, 20 m sprint, 10x5 agility, leg strength, right/left hand grip strength, 20 m shuttle run and balance tests were also performed. Statistically differences were found between anthropometric measurements apart from height and BMI, 2D:4D and physical fitness parameters in the males and females. A negative correlation between right hand 2D:4D and vertical jumping, standing long jump, 20 m sprint, 10x5 agility and right hand grip strength in the males. As for the females, although a negative correlation was detected between right hand 2D:4D and height, a positive correlation was found between the same variable and body fat ratio (p<0.05). It can be concluded that while a low 2D:4D ratio was correlated with static and explosive strength, speed and agility in the males, it was correlated with height and body fat ratio in the females.

Abstract Context Severe vitamin D deficiency may lead to myopathy in adults. Little is known about vitamin D and muscle strength in children. Objective To test whether hand grip strength (HGS) in 5-year-old children is associated with serum 25-hydroxyvitamin D (S-25OHD). Design Observational study in the population-based Odense Child Cohort, Denmark. At 5 years, anthropometrics, body fat percentage by skinfold measurements, HGS (n = 881), and S-25OHD2+3 (n = 499) were obtained. Results Mean (SD) HGS was higher for boys compared with girls [8.76 (1.76) vs 8.1 (1.64) kg, P &lt; 0.001]. Mean (SD) 5-year S-25OHD was 70.7 (24.5) nmol/L. HGS was directly associated with height in girls and with weight (directly) and body fat percentage (inversely) in both sexes (P &lt; 0.01 for all). In girls, 5-year S-25OHD was associated with HGS, adjusting for height, weight, and body fat percentage [β = 0.011 (95% CI: 0.004; 0.019), P = 0.003]. S-25OHD ≥75 nmol/L was associated with higher HGS compared with values &lt;50 nmol/L [adjusted β = 0.783 (95% CI: 0.325; 1.241), P = 0.001]. The odds of having myopathy (HGS &lt;10th percentile) were reduced by approximately 70% for S-25OHD ≥50 vs &lt;50 nmol/L [adjusted OR: 0.310 (95% CI: 0.126; 0.762), P = 0.011]. No associations were seen for boys. Pregnancy or umbilical cord S-25OHD did not associate with 5-year HGS. Conclusions Five-year S-25OHD was independently associated with HGS and myopathy in girls but not in boys. Muscle strength may be dependent on vitamin D status even in the higher range in preschool girls. The sex difference remains unexplained.

Body composition can affect a police officer’s physical performance. We analyzed the correlation between body fat percentage (%fat) and physical performance in 326 male Korean police officers (age, 44.2 ± 9.2 years; height, 174.0 ± 4.5 cm; weight, 76.4 ± 8.8 kg) who were classified into two groups according to their %fat: high-fat (HFG, %fat ≥ 25%; n = 135) and low-fat (LFG, %fat < 25%; n = 191). Physical performance tests included a 100-m sprint, push-ups, sit-ups, and a hand-grip strength test. The results showed significant differences in performance between the groups in the 100-m sprint (p = 0.001) and in the sit-up test (p = 0.033), but not for push-ups (p = 0.130) or hand-grip strength (p = 0.255). A significant positive correlation was found between %fat and the 100-m sprint (r = 0.255, p < 0.000), and a negative correlation was found between %fat and push-ups (r = −0.117, p = 0.035) and sit-ups (r = −0.199, p < 0.000). However, there was no significant correlation between %fat and hand-grip strength (r = −0.093, p = 0.095). To improve physical performance, an intervention training program is recommended for reducing %fat, because high levels of %fat in male Korean police officers were associated with low levels of physical performance.

Abstract Introduction: Physical exercise is used as a strategy for the prevention of falls because it improves the physical fitness of older adults. Objective: To determine which components of physical fitness are predictors of falls in elderly female exercise practitioners. Method: Longitudinal, descriptive, comparative study. The components of physical fitness (upper and lower limb strength and flexibility, agility, aerobic endurance, and hand grip strength) and the occurrence or not of falls in the last 12 months were analyzed in 80 older women practitioners of exercise from 2013 to 2016. Descriptive analysis, ROC curve attributing cut-off points, and binary logistic regression for the prediction of falls were used. Results: The mean age of the participants was 67.46 years (SD=7.65). Over the years, a significant difference between elderly fallers and non-fallers was observed for right hand grip strength (2013 and 2015), left hand grip strength (2014 and 2015), lower limb flexibility (2013, 2014 and 2015), agility (2015), and aerobic endurance (2015). In adjusted analysis, older women with poor lower limb flexibility in 2013 had a higher risk of falls in 2016 (OR=4.98; 95%CI 1.12 - 22.1). Older women with poor flexibility in 2015 also had a higher risk of falls (OR= 6.08; 95%CI 1.06 - 34.67). Conclusion: Poor performance in the lower limb flexibility, right and left hand grip strength, agility and aerobic endurance tests was associated with falls and these components are predictors of future falls in elderly exercise practitioners.

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。

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.
