purpose to verify whether active recovery (ar) applied after a kickboxing match resulted in better performance in anaerobic tests when compared to passive recovery (pr). methods eighteen kickboxers volunteered to participate on a kickboxing match preceded and followed by anaerobic tests: squat jump (sj), the counter movement jump (cmj) and the upper-body wingate test. blood lactate (bl), heart ...

This study examined the effects of baseline flexibility and vertical jump ability on straight leg raise range of motion (ROM) and counter-movement jump performance (CMJ) following different volumes of stretching and potentiating exercises. ROM and CMJ were measured after two different warm-up protocols involving static stretching and potentiating exercises. Three groups of elite athletes (10 ma...

Plyometric training is popular among individuals involved in dynamic sports, and plyometric exercises such as jumping, hopping, skipping and bounding are executed with the goal of increasing dynamic muscular performance, especially jumping. Much less information is available on the effectiveness of plyometric training (PT) in badminton, where jumping high (e.g. forehand overhead jump-smash) is ...

The purpose of the present study was to investigate the explosive strength and endurance adaptations in young elite soccer players who underwent a supervised training program for a period of two years. Nineteen players, with seven years of training experience (age: 13.3 ± 0.1 years; body weight: 57.9 ± 4.9 kg; height: 168.9 ± 4.7 cm; BMI: 20.1 ± 1.1 kg/m2), voluntarily participated in the prese...

On Earth, when landing from a counter-movement jump, muscles contract before touchdown to anticipate imminent collision with the ground and place the limbs in a proper position. This study assesses how the control of landing is modified when gravity is increased above 1 g. Hypergravity was simulated in two different ways: (1) by generating centrifugal forces during turns of an aircraft (A300) a...

Abstract Explosive actions are integral to soccer performance and highly influenced by the ability generate maximal power. The purpose of this study was investigate relationship between force-velocity profile, jump performance, acceleration sprint speed in elite female players. Thirty-nine international players (24.3±4.7 years) performed 40-m sprints, countermovement jumps five loaded squat at ...

Regarding the effects of the kinematics of the movement on athletic performance and the Importance of promoting athlete’s performance on the sport fields, there is limited knowledge about the mechanism of the effect of different variables of volleyball spike. Therefore, the aim of this study was the prediction of jump performance in elite female volleyball players with selected kinematic variab...

Hamstrings injury is a common occurrence in athletic performance. These injuries tend to occur during a deceleration or landing task suggesting the negative work may be a key component in hamstrings injury. The purpose of this study was to investigate the muscular activity (EMG) of the biceps femoris (BF) in different phases (concentric vs. eccentric) of a Counter Movement Jump (CMJ), Squat Jum...
