the purpose of this study was to determine relationship between anthropometric, physiological and body composition characteristics of male elite taekwondo athletes with their success. for this 20 elite male taekwondo (age 25.75, weight 73.6, height 180.55) that invited to national team selected. anthropometric characteristics including weight, height, body fat percentage, bmi, and biomotor and ...

This study examined the potential relationship between participation in physical activity (PA) assessed by triaxial accelerometry and physical fitness testing, including health-related and skill-related parameters of fitness, in 136 Japanese preschoolers (65 girls and 71 boys, 5.5 ± 0.6 years). In partial correlation analyses, grip strength and 20m shuttle run test were positively correlated w...

The aim of this study was to determine if maximal effort, evidenced by peak HR was attained during the 20m shuttle-run test in a naturalistic setting. Shuttle-run test performance and peak HR were measured in 208 volunteers (11-16 years). Peak HR was 196 (95% confidence interval (C.I.) 194-198 bpm). The relationship between test performance and peak HR was assessed by regression. There was a we...

We examine the observable properties of simulated barred galaxies including radial mass profiles, edge-on structure and kinematics, bar lengths and pattern speed evolution for detailed comparison to real systems. We have run several simulations in which bars are created through inherent instabilities in self-consistent simulations of a realistic disc+halo galaxy model with a disc-dominated, fla...

Static stretching has often been found to decrease performance in power and speed activities, but dynamic warm-ups usually increase performance. We examined the effects of a mini-band warm-up, a medicine ball warm-up, and static stretching on 10m and 20m sprint times, as well as overhead medicine ball throw performance. Twenty-four Division I female soccer players completed the three warm-ups a...

Materials and methods Ninety-day-old female Wistar rats were divided into three groups: exercised-control (EC; n=5), high intensity exercised-diabetic (HIED=high intensity training, 80% of the maximum speed in the stress test; n=4) and low intensity exercised-diabetic (LIED=low Intensity training, 40% of the maximum speed in the stress test; n=6). The diabetes was induced in the rats by adminis...

AIM To assess Cardio-respiratory fitness (CF) markers among university students using a 20m shuttle run test (SRT). METHODS Markers of CF were assessed in 80 males aged 21.4±1.8 years, randomly selected from Moi University, Kenya. Assessed at different stages of SRT protocol included heart rate (HR), systolic and diastolic blood pressure (SBP & DBP). VO2max was also determined. Data were anal...

The aims of this study were firstly, to examine the relationship between repeated sprint performance indices and anaerobic speed reserve (AnSR), aerobic fitness and anaerobic power and secondly, to identify the best predictors of sprinting ability among these parameters. Twenty nine subjects (age: 22.5 ± 1.6 years, body height: 1.8 ± 0.1 m, body mass: 68.8 ± 8.5 kg, body mass index (BMI): 22.2 ...
