Effect of movement goal on countermovement jump performance: An exploratory analysis of different sporting demands

This study explored the influence of different counter movement jump (CMJ) goals on performance, kinetic, and kinematic variables between 56 elite track and field (T&F), football, and futsal athletes.

THE EFFECT OF REPEATED COUNTERMOVEMENT JUMPS TO FAILURE ON VERTICAL JUMP PERFORMANCE

The aim of this study is to determine changes through repeated countermovement jumps to failure and to determine which of these changes persist after the induction of fatigue. Twenty-eight students (mean age of 19.24±0,99 years, height of 176.90±8.93 cm, and body weight of 73.45±11.48 kg) were included in this study.

Which drop jump technique is most effective at enhancing countermovement jump ability, “countermovement” drop jump or “bounce” drop jump?

Journal of Sports Sciences, 2013
The drop jump is a popular form of plyometric exercise often undertaken to enhance countermovement jump ability (jump height). Despite its popularity the effects of drop jump training on countermovement jump height are often inconsistent. Such inconsistencies may be as a result of differences in the drop jump technique being employed.

Choice of jumping strategy in two standard jumps, squat and countermovement jump‐effect of training background or inherited preference?

Scandinavian Journal of Medicine and Science in Sports, 1999
Six male subjects, three professional ballet dancers and three elite volleyball players, performed maximal vertical jumps from 1) a static preparatory position (squat jump), 2) starting with a countermovement (counter‐movement jump) and 3) a specific jump for ballet and for volleyball, respectively.

Dimensionality Reduction for Countermovement Jump Metrics

International Journal of Sports Physiology and Performance, 2021
Purpose:Dozens of variables can be derived from the countermovement jump (CMJ). However, this does not guarantee an increase in useful information because many of the variables are highly correlated. Furthermore, practitioners should seek to find the simplest solution to performance testing and reporting challenges.

Biomechanical analysis of drop and countermovement jumps

European Journal of Applied Physiology and Occupational Physiology, 1986
For 13 subjects the performance of drop jumps from a height of 40 cm (DJ) and of countermovement jumps (CMJ) was analysed and compared. From force plate and cine data biomechanical variables including forces, moments, power output and amount of work done were calculated for hip, knee and ankle joints.

The effects of arms and countermovement on vertical jumping

Medicine & Science in Sports & Exercise, 1990
Countermovement and arm-swing characterize most jumping. For determination of their effects and interaction, 18 males jumped for maximal height from a force platform in all four combinations of arm-swing/no-arm-swing and countermovement/no-countermovement. For all jumps, vertical velocity peaked 0.03 s before and dropped 6-7% by takeoff.
