Impact Forces From Jumping Depend on Jump Height

open access: yesJournal of Bone and Mineral Research, 2001
We thank Dr. Bassey for explaining the statement made in her earlier article regarding the measurement of ground reaction forces. Furthermore, we wish to take this opportunity to respond to her use of “high impact.” In her letter, Dr. Bassey states “Jumping produces high impact, even when the jumps are small and suitable for middle-aged and sedentary ...

The validity and reliability of the “My Jump App” for measuring jump height of the elderly [PDF]

open access: yesPeerJ, 2018
Background The ability to jump has been related to muscle strength and power, speed and amplitude of the lower limbs movements, and specifically for the elderly, the vertical jump has been shown to be a good predictor of functional capacity and risk of ...

The hydraulic bump: The surface signature of a plunging jet [PDF]

open access: yes, 2013
When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact provided a critical flow rate is exceeded.

Torque pattern generation towards the maximum jump height [PDF]

open access: yesProceedings 2006 IEEE International Conference on Robotics and Automation, 2006. ICRA 2006., 2006
This paper discusses jumping pattern generation for a serial link robot in order to maximize its jump height under torque limitation. By applying a genetic algorithm (GA) for determining torque assignment, we obtain various jumping patterns with respect to the torque limitation for a fixed mass of the robot.

Comparison of Various Devices Used in the Evaluation of Vertical Jump Height

open access: yesPamukkale Spor Bilimleri Dergisi, 2023
This study aimed to compare force plate, motion analysis, and mobile application methods for calculating vertical jump height. Twenty-nine male college students (age: 22.4 ± 1.0 years; height: 178.1 ± 6.2cm; body weight: 71.2 ± 8.0 kg) voluntarily ...

The effect of training with weightlifting catching or pulling derivatives on squat jump and countermovement jump force–time adaptations [PDF]

open access: yes, 2020
The purpose of this study was to examine the changes in squat jump (SJ) and countermovement jump (CMJ) force−time curve characteristics following 10 weeks of training with either load-matched weightlifting catching (CATCH) or pulling derivatives (PULL ...

Kinetic parameters as determinants of vertical jump performance

open access: yesRevista Brasileira de Cineantropometria e Desempenho Humano, 2011
The aim of this study was to identify force and velocity parameters related to vertical jump performance in counter movement jump (CMJ) and squat jump (SJ), and to compare these parameters between sprint runners and volleyball players.

An examination of jump kinematics in dogs over increasing hurdle heights [PDF]

open access: yes, 2016
Research examining kinematic parameters of the canine athlete is markedly behind equivalent human and equine research. With increasing participation and popularity, canine sports science needs to bridge this gap with comparable equine research.

Analysis of standing vertical jumps using a force platform [PDF]

open access: yes, 2001
A force platform analysis of vertical jumping provides an engaging demonstration of the kinematics and dynamics of one-dimensional motion. The height of the jump may be calculated (1) from the flight time of the jump, (2) by applying the impulse–momentum
