Seventeen university students performed two blocks of 18 countermovement jumps (CMJ) being instructed to jump for maximum height after performing the countermovement at a self-selected (SS-CMJ) or fast (F-CMJ) velocity. Each block consisted of six CMJ from a larger depth, six CMJ from a ...
摘要: Ankle sprain is one of the most common sport injuries in lower extremities. It frequently occurs in landing phase when athletes perform jumping. The counter movement jump and straddle jump are common jumping strategies often used in baseball and volleybal关键词:...
There are many different ways of how to measure your vertical jump, but the most common methodology is the "Sargent Test" where the height of a countermovement jump from a standstill is measured. This test is a great tool to get an idea about the lower-body strength of athletes but one ...

We evaluated the effect of performing various distinct warm-up exercises on vertical countermovement jump (VCMJ) performance. Eight volleyball players (age 15.4 ± 0.5 yrs) performed five different warm-up activities (in a counterbalanced, randomized crossover study) over five days, at 24-h inter...
The article presents research on the effects of the volume and load of back squats on vertical jump performance by athletes. Women volleyball players executed vertical jumps following a series of back squat weight lifting. It was found that heavy load squats improved the vertical stiffness of the...
Validity of a contact mat and accelerometric system to assess countermovement jump from flight time Countermovement jump (CMJ) height is an important parameter in physical performance. This study compared CMJ height measured using ChronoJump contact mat (... R Stanton,TM Doering,C Macgregor,......
The acute effects of manipulating the volume and load of back squats on subsequent countermovement vertical jump performance were investigated in the present study. Eleven National Collegiate Athletic Association division II female volleyball players performed 10 countermovement vertical jumps (CMJs) on a...
Squat jump, counter-movement jump and drop jump height were measured on three occasions before the race. The track tests were repeated on days 4, 11, 18, 25 and 32 after the race. The vertical jump tests were repeated on the day of the race and on days 1, 2, 3, 4, 5, 11, 18...
