Bilateral Facilitation and Laterality during the Countermovement Jump
Perceptual and Motor Skills, 2009This 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.

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, 2007The 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, 2016Reliability 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, 2011AbstractThe 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

The countermovement jump to monitor neuromuscular status: A meta-analysis
Journal of Science and Medicine in Sport, 2017The 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).

Differences in the utilisation of active power in squat and countermovement jumps
European Journal of Sport Science, 2017AbstractThe aim of this article was to understand how active power is used in squat and countermovement jumps. A simple empirical model comprising a mass, a spring, an active element and a damper, together with an optimisation principle, was used to identify the mechanical factors that maximise performance of jumps without countermovement (squat jumps,

Biomechanical Characteristics of the Countermovement Jump
2019The 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.

The effects of added mass on the biomechanics and performance of countermovement jumps
Journal of Sports Sciences, 2019This study examined the kinetic and temporal differences between countermovement jumps (CMJs) and eccentrically loaded CMJs. A survey of 109 coaches and athlete showed that 87% of respondents regularly used jumps with added mass within training. Sixteen male and thirteen female track and field athletes from sprinting, hurdling and jumping events ...
