The participants were randomly allocated into control group (CG) and experimental (EG)...

Balance, reaction time, and strength are key factors affecting judo performance. Although ample research has been done examining potential changes caused by weight loss prior to competition, in balance time have overlooked.To examine the effects of rapid progressive (RWL PWL) on balance, a group elite athletes.A total 38 female male athletes (age = 20.6 [2.6] y) completed reaction-time, assessments 1 wk an official weigh-in (pretest) immediately after (posttest). The were divided into 3...

Basketball players commonly use mouthguards for protecting their mouths from collisions with other players. Besides, literature reports that specific types of may become an ergogenic device facilitates a powerful jaw clenching, and subsequent concurrent activation potentiation through this remote voluntary contraction the mandible muscles.A randomized within-subjects design was used to study effects mechanism on muscular performance (vertical jump, agility, bench press power leg power) into...
