The Relationship between Isometric Force Characteristics and Vertical Jump Height under Various Loading Conditions.
… between isometric force characteristics (IF) and vertical jump height under various loading conditions. Sixty-three collegiate athletes participated in this investigation. Athletes performed static jump (SJ) and countermovement jumps (CMJ) with 0 and 20kg, and isometric mid-thigh pulls on a force …

Dynamic exoskeleton : design and analysis of a human exoskeleton to enhance maximum dynamic performance
… is intended to enable to the user to run faster, jump higher, or traverse challenging terrain. This thesis presents a study on improving human vertical jump height using a powered exoskeleton. A simple human jump model is created, and dynamic simulation is utilized to determine the effectiveness …

The Interrelationships of Fitness Characteristics in Division 1 Athletes
… to almost all sports include strength, power, vertical jump height, shortdistance sprinting ability, muscularity, and body fat percentage. These variables have been shown in previous research to independently affect athletic performance outcomes, but their relationships to one another are less …

Dynamic exoskeleton : mechanical design of a human exoskeleton to enhance maximum dynamic performance
… a human, thus allowing the user to run faster, jump higher, or traverse challenging terrain. This paper presents the mechanical design of an alpha prototype with a focus on increasing the maximum vertical jump height of a human. High torque motors were constrained to the body with two degrees of …

TRAINING COMPARISON: 95%VO2PEAK vs. RACE PACE INTERVALS
… time trial performance, peak power output, and vertical jump height in recreationally active subjects. METHODS: 34 subjects were randomly assigned to one of four training groups (TM-95%, Cycle-95%, TM-RP, Cycle-RP). Pre- and post- study, all subjects performed a ramped protocol test to …

Influence of physical training on knee valgus motion and physical performance abilities among adole[s]cent female basketball players
… (including a warm-up and plyometric, jump, flexibility, and strength training) would decrease valgus motion at the knee joint upon impact of a jump landing task. In addition, another aim of the investigation was to determine if the training routine would enhance physical performance …

The effects of a heavy resistance training intervention of the plantar flexors on the recovery of strength, power, acceleration, and agility in recreational athletes
… such as maximal voluntary isometric strength, vertical jump height, standing broad jump, 10m sprinting speed, and the Illinois Agility run. The subjects were recreationally active, but non•resistance trained, males between the age of 18 and 45. The subjects completed 10 testing sessions, four …

The Effect of a Skate Treadmill Training Intervention on Stride Mechanics
… anthropometric measures of [standing and sitting height (cm), weight (kg)], vertical jump height (cm), and stride mechanics. Stride mechanics, namely SL (mm), SF (Hz), and joint angles (°), were obtained from video analysis conducted at a constant treadmill speed (10 mph) and incline (5 °). While …
