Student Movement in Contemporary Iran; Independent or Affiliated Movement
The student movement is considered as one of the important issues of Iranian political sociology, but its role and its nature and its relationship with other movements and movements in Iran have been discussed. The present article is trying to answer the role and function of the student movement in Iran. Using a descriptive-analytic approach, political currents have become instrumental in most ...
متن کاملRelationship between Ball Kick Velocity and Leg Strength: A Comparison between Soccer Players and Other Athletes
This study compared soccer players with non-soccer players, with respect to the relationship between ball velocity due to an instep kick and various leg strengths. Ten young university soccer players and ten other athletes (non-soccer players) had their instep kick ball velocity (BV) measured with respect to isokinetic leg strength. The BVs from the soccer players were significantly greater tha...
متن کاملWater striders adjust leg movement speed to optimize takeoff velocity for their morphology
Water striders are water-walking insects that can jump upwards from the water surface. Quick jumps allow striders to avoid sudden dangers such as predators' attacks, and therefore their jumping is expected to be shaped by natural selection for optimal performance. Related species with different morphological constraints could require different jumping mechanics to successfully avoid predation. ...
متن کاملEffects of moderate-velocity strength training on peak muscle power and movement velocity: do women respond differently than men?
The effects of a 10-wk unilateral knee extension strength training (ST) program on peak power (PP) and peak movement velocity (PV), at given absolute (force load) and relative (same % of 1 repetition maximum) resistances (loads), were examined in 30 older men [64 yr (7 SD)] and 32 older women [62 yr (6 SD)]. PP increased significantly in both men and women at the same absolute (P < 0.001) and r...
متن کاملTITLE: Movement velocity as a measure of exercise intensity in three lower limb exercises RUNNING HEAD: Movement strength velocity and intensity
The purpose of this study was to investigate the relationship between movement velocity and relative load in three lower limbs exercises commonly used to develop strength: Leg Press, Full Squat, and Half Squat. The percentage of one Repetition Maximum (%1RM) has typically been used as the main parameter to control resistance training, however more recent research has proposed movement velocity ...
