Kinematic Mechanisms of How Power Training Improves Healthy Old Adults’ Gait Velocity
WALKING MUSCLE AGING BIOMECHANICS EXERCISE
2018/4/24
Introduction Slow gait predicts many adverse clinical outcomes in old adults, but the mechanisms of how power training can minimize the age-related loss of gait velocity is unclear. We examined the ef...
Relationship between Leg Mass, Leg Composition and Foot Velocity on Kicking Accuracy in Australian Football
muscle impulse relative variability coordination
2016/7/7
Kicking a ball accurately over a desired distance to an intended target is arguably the most important skill to acquire in Australian Football. Therefore, understanding the potential mechanisms which ...
Muscle contraction velocity,strength and power output changes following different degrees of hypohydration in competitive olympic combat sports
Hydration Urine osmolality Bench press Taekwondo Olympic wrestling and boxing
2016/5/16
Background:It is habitual for combat sports athletes to lose weight rapidly to get into a lower weight class. Fluid restriction, dehydration by sweating (sauna or exercise) and the use of diuretics ar...
Predicting Vertical Jump Height from Bar Velocity
Linear velocity transducer force platform jump performance swimming
2015/8/28
The objective of the study was to assess the use of maximum
(Vmax) and final propulsive phase (FPV) bar velocity to predict
jump height in the weighted jump squat. FPV was defined as the
velocit...
The interseismic velocity field of the central Apennines from a dense GPS network
Solutions combination GPS surveys
2015/8/26
Since 1999, we have repeatedly surveyed the central Apennines through a dense survey-style geodetic network, the Central Apennines Geodetic Network (CAGeoNet). CAGeoNet consists of 123 benchmarks dist...
Wayfinding,displacements,and mental maps:Velocity fields are not typically used to determine one's heading
Wayfinding displacements mental maps Velocity fields typically determine
2015/8/13
When an individual moves through a cluttered environment, he or she often fixates an object relatively near his or her path in the middle distance and uses pursuit eye movements to follow it while mov...

Effects of A 6-Week Junior Tennis Conditioning Program on Service Velocity
tennis strength flexibility service performance
2015/5/15
This study examined the effects of a 6-week strength-training program on serve velocity in youth tennis players. Thirty competitive healthy and nationally ranked male junior tennis players (13 years o...
Effects of run-up velocity on performance, kinematics, and energy exchanges in the pole vault
Sports biomechanics kinematics
2015/5/11
This study examined the effect of run-up velocity on the peak
height achieved by the athlete in the pole vault and on the correponding changes in the athlete’s kinematics and energy exchanges.
