The load-velocity relationship in the jump squat exercise. [PDF]
Biol Sport, 2023 The purpose of this study was to test the load-velocity relationship in the jump squat (JS) exercise using three different velocity parameters (mean velocity [MV], mean propulsive velocity [MPV], and peak velocity [PV]). Twenty-six male rugby union players (24.3 ± 3.9 years; 1.81 ± 0.09 m; 101.3 ± 15.4 kg) performed a progressive loading test in the JS

Analysis and Comparison of Motion Biomechanics Characteristics of Squat Jump and Half-Squat Jump
Mobile Information Systems, 2022 In order to study the biomechanical characteristics of squat jump and half-squat jump, analysis and comparison were made. This paper tests and analyzes the kinematics and dynamics of 63 young men’s squat jump, and synchronously collects the kinematics and dynamics data of subjects in the process of weight-bearing squat, in-situ free jump, and high ...

Post-Isometric Back Squat Performance Enhancement of Squat and Countermovement Jump
International Journal of Environmental Research and Public Health, 2022 The effectiveness of isometric conditioning activity (CA) is not well described in terms of the level of performance enhancement and the presence of a stretch and shortening cycle in subsequent explosive tasks. Therefore, the aim of this study was to evaluate the effect of a maximum isometric squat as the CA and a subsequent squat jump (SJ) and ...

Humans adjust control to initial squat depth in vertical squat jumping [PDF]
Journal of Applied Physiology, 2008 The purpose of this study was to gain insight into the control strategy that humans use in jumping. Eight male gymnasts performed vertical squat jumps from five initial postures that differed in squat depth (P1–P5) while kinematic data, ground reaction forces, and electromyograms (EMGs) of leg muscles were collected; the latter were rectified and ...

Risk of injury analysis in depth jump and squat jump [PDF]
Journal of Human Sport and Exercise, 2021 Introduction: The depth jump (DJ) and squat jump (SJ) are accepted ways to assess and train power producing ability but are not without risk of injury. Methods: Sixteen male participants (age = 21.7 ± 1.54 yrs., height = 177.7 ± 11.4 cm, mass = 77.7 ± 13.6 kg) were evaluated for power exertion capabilities while being assessed for risk of injury in the

Conditioning exercises in ski jumping: biomechanical relationship of squat jumps, imitation jumps, and hill jumps [PDF]
Sports Biomechanics, 2017 As hill jumps are very time-consuming, ski jumping athletes often perform various imitation jumps during training. The performed jumps should be similar to hill jumps, but a direct comparison of the kinetic and kinematic parameters has not been performed yet.

Determinant Factors of the Squat Jump in Sprinting and Jumping Athletes [PDF]
Journal of Human Kinetics, 2017 Abstract The aim of this study was to assess the relationship between strength variables and maximum velocity (Vmax) in the squat jump (SJ) in sprinting and jumping athletes. Thirty-two sprinting and jumping athletes of national level (25.4 ± 4.5 years; 79.4 ± 6.9 kg and 180.4 ± 6.0 cm) participated in the study.

Jumping for distance: control of the external force in squat jumps [PDF]
Medicine & Science in Sports & Exercise, 1999 It was investigated whether control in jumps for distance is related to control in jumps for height.Five male subjects performed maximum squat jumps in the following conditions: VJ (vertical jump), LJ (long jump), and two conditions with inclination angles of the body relative to the horizontal of 75 and 65 degrees, respectively.
