This study investigated the differences in joint motions and muscle activities of the lower extremities involved in various squatting postures. The motion capture system with thirty-one reflective mar...
Self-Paced and Temporally Constrained Throwing Performance by Team-Handball Experts and Novices without Foreknowledge of Target Position
Throwing velocity throwing accuracy visual control postural control expertise level
2015/5/26
The fixed duration of a team-handball game and its continuously changing situations incorporate an inherent temporal pressure. Also, the target’s position is not foreknown but online determined by the...
Effects of Strength vs. Ballistic-Power Training on Throwing Performance
Shot put muscle fibres ultrasound ballistic training muscle mass
2015/5/14
The purpose of the present study was to investigate the effects of 6 weeks strength vs. ballistic-power (Power) training on shot put throwing performance in novice throwers. Seventeen novice male shot...

A Load-Velocity Relationship for Men and Women in Overhead Throwing Performance
A Load-Velocity Relationship Men and Women Overhead Throwing Performance
2015/5/5
TIn many movements, resistance (load) and velocity are inversely related to each other (Schilling et al., 2008). This relationship is often ascribed to skeletal muscle properties. Hill, 1938 described...
Relationship Between Maximum Shoulder External Rotation Angle During Throwing and Physical Variables
Throwing shoulder elbow injury prevention
2015/4/7
The amount of stress imposed on shoulder and elbow appears to be directly correlated with the degree of maximum shoulder external rotation (MER) during throwing motions. Therefore, identifying risk fa...
