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 ...

abstract the aim of this study was to investigate the relationship between some anthropometric parameters and physiological tests (physical fitness) in amateur soccer players. the present study was descriptive-comparative carried out as a field study. the statistical population consisted of male adolescent soccer players (9-13 years old) who volunteered to participate in leisure time programs o...

abstract many studies have been conducted on the characteristics of hydraulic jump over gradually expanding cross sections, but comparatively few have been carried out on basins with convergent wall. in the present research, the hydraulic jump characteristic of the stilling basin with convergent wall has been investigated. the main objective of this research is evaluation of conjugate depths ra...

hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the   jump. this paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view. a minimum value of upstream froude number is needed to produce the free hydraulic jump on adverse stilling basins which was presented by a theoretical...

conclusions the he jump mat can be recommended in relation to the validity of constraints. in this study, only a part of the quality criteria were examined. for the final recommendation it is advised to examine the he jump mat on the other quality criteria (test-retest reliability, sensitivity change). background in the field of vertical jump diagnostics, force plates (fp) are the reference sta...

A study was performed to evaluate effects of elastic energy stored pre-stretch on the mechanical work output while performing vertical jump. Eight male volunteers of age between 21 29 years old participated in the present study. The present study hypothesized that the vertical jump height during countermovement jumps (CMJ) would be higher than that during squat jump (SJ). During squat jump, a v...

background: physical exercises can influence some anthropometric and fitness components differently. the aim of present study was to evaluate how a relatively long‑term training program in 11‑14‑year‑old male iranian students affects their anthropometric and motor performance measures. methods: measurements were conducted on the anthropometric and fitness components of participants (n = 28) pri...

abstract one of the most frequently encountered cases of rapid varied flow is the hydraulic jump. it occurs when a supercritical open channel flow changes into sub critical flow. in the present research, the experimental study of the hydraulic jump on seven sinusoidal corrugated beds with different wave steepness. the wave steepness of sinusoidal corrugated beds is in the range of 0.1667 to 0.7...

Background. This study aimed to analyze core muscle fatigue effects on the kinematic parameters change during volleyball jump serve. Methods. The participants were sixteen experienced male volleyball players with average age, height, and body weight of 24.6 ± 1.8 years, 1.85 ± 1.6 m, and 79.5 ± 3.5 kg, respectively. This study utilized two high-resolution video cameras, a drone video, a lactat...
