Passive Knee Exoskeleton Increases Vertical Jump Height

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022
Most exoskeletons are designed to reduce the metabolic costs of performing aerobic tasks such as walking, running, and hopping. This study presents an exoskeleton that boosts vertical jumping-a fast, short movement during which the muscles are exerted at peak capacity.

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

Influence of body composition on vertical jump performance according with the age and the playing position in football players [PDF]

open access: yes, 2015
Body composition and vertical jump are two factors in the multifactorial approach to talent identification in soccer with implication on performance monitorization and injury rehabilitation.

Quantifying the onset of the concentric phase of the force–time record during jumping [PDF]

open access: yes, 2009
Thirteen college students performed a drop jump from height equal to their peak vertical jump, single leg jumps from the left and right legs, and a counter movement jump.

Development of a method to identify foot strike on an arena surface: application to jump landing [PDF]

open access: yes, 2010
Foot strike can be difficult to determine using kinematics alone, particularly when studying equine activities on more compliant surfaces, so this study was done with the aim of developing and validating a method to determine foot strike on an arena ...

Muscular coordination during vertical jumping [PDF]

open access: yes, 2019
The musculoskeletal system has a relatively large number of mechanical degrees of freedom. In order to permit coordinated movement, it is thought that these degrees of freedom are constrained, reducing the complexity of the motor control problem.

Control of maximal and submaximal vertical jumps [PDF]

open access: yesMedicine & Science in Sports & Exercise, 2000
It was investigated to what extent control signals used by human subjects to perform submaximal vertical jumps are related to control signals used to perform maximal vertical jumps.Eight subjects performed both maximal and submaximal height jumps from a static squatting position.

Effect of single vs. multi joint ballistic resistance training upon vertical jump performance [PDF]

open access: yes, 2013
The present study aimed to examine the effects of two different ballistic resistance training regimens, with and without the possibility to utilize the proximal to distal coordination between knee and ankle, upon maximal vertical jump performance ...

Pengaruh Latihan Depth Jump dan Knee Tuckjump terhadap Peningkatan Vertical Jump pada Siswa Putra Ekstrakurikuler Voli di SMAN 2 Ngadirojo Pacitan [PDF]

open access: yes, 2016
Vertical jump is one of the most important elements in the sport of volleyball. Vertical jump is a complex process that involves strength, speed and endurance of the muscles of the leg.
