Bilateral Facilitation and Laterality during the Countermovement Jump

Perceptual and Motor Skills, 2009
This study assessed bilateral facilitation and laterality during counter-movement jumps. 23 NCAA Division-I athletes (13 men, 10 women) who participated in track and field volunteered to serve as participants and performed bilateral, right, and left leg countermovement jumps on a force plate.

Countermovement Jump Height

Journal of Strength and Conditioning Research, 2014
The goal of this study was to assess (a) the eccentric rate of force development, the concentric force, and selected time variables on vertical performance during countermovement jump, (b) the existence of gender differences in these variables, and (c) the sport-specific differences.

GENDER BIAS IN THE EFFECTS OF ARMS AND COUNTERMOVEMENT ON JUMPING PERFORMANCE

Journal of Strength and Conditioning Research, 2007
The ability to jump high is considered important in a number of sports. It is commonly accepted that the use of the arms and a counter movement increase jump height. In some sport situations (e.g., volley ball block, basketball rebound), athletes may not be able to utilize a counter movement or arm swing.

Reliability of Squat Jump and Countermovement Jump Performance in Masters Athletes

La Prensa Medica, 2016
Reliability of Squat Jump and Countermovement Jump Performance in Masters Athletes Despite their widespread use in performance assessment in younger athletes, the reliability of squat jump (SJ) and countermovement jump (CMJ) assessments has not been reported in master’s athletes.

Countermovement jump in performance diagnostics: Use of the correct jumping technique

European Journal of Sport Science, 2011
AbstractThe aim of this study was to examine the effects of arm‐swing and sporting activity on jump height and jump height variability of countermovement jumps in adolescent students to inform correct jumping technique in different settings. Altogether, 324 students (grades 5–11) performed three countermovement jumps with bilateral arm‐swings and three

A comparison of one-legged and two-legged countermovement jumps

Medicine & Science in Sports & Exercise, 1985
Ten well-trained male volleyball players performed one-legged and two-legged vertical countermovement jumps. Ground reaction forces, cinematographic data, and electromyographic data were recorded. Jumping height in one-legged jumps was 58.5% of that reached in two-legged jumps.

The countermovement jump to monitor neuromuscular status: A meta-analysis

Journal of Science and Medicine in Sport, 2017
The primary objective of this meta-analysis was to compare countermovement jump (CMJ) performance in studies that reported the highest value as opposed to average value for the purposes of monitoring neuromuscular status (i.e., fatigue and supercompensation).

Biomechanical Characteristics of the Countermovement Jump

2019
The countermovement jump is the closest to natural human movement among all biomechanical types of jumps and involves the movement of the whole body. Jump height is understood as a maximal lift of the jumping person’s general centre of gravity in the flight phase with respect to the baseline position at the moment of take-off.
