Comparison of Ball-And-Racket Impact Force in Two-Handed Backhand Stroke Stances for Different-Skill-Level Tennis Players
Biomechanics upper extremity kinetic acceleration open stance square stance
2016/7/7
This study compared the kinetic roles of the upper extremities in racket impact force generation between the open stance (OS) and square stance (SS) for tennis players with different skill levels in t...
Effects of Prophylactic Ankle Supports on Vertical Ground Reaction Force During Landing:A Meta-Analysis
Ankle brace athletic tape ankle sprain anterior cruciate ligament
2016/3/11
There has been much debate on how prophylactic ankle supports (PASs) may influence the vertical ground reaction force (vGRF) during landing. Therefore, the primary aims of this meta-analysis were to s...
Acute Effects of Foot Rotation in Healthy Adults during Running on Knee Moments and Lateral-Medial Shear Force
Osteoarthritis cartilage biomechanics gait
2016/3/11
As runners age, the likelihood of developing osteoarthritis (OA) significantly increases as 10% of people 55+ have symptomatic knee OA while 70% of people 65+ have radiographic signs of knee OA. The l...
Creatine supplementation enhances muscle force recovery after eccentrically-induced muscle damage in healthy individuals
Creatine supplementation enhances muscle force muscle damage healthy individuals
2015/7/16
Eccentric exercise-induced damage leads to reductions in muscle force, increased soreness, and impaired muscle function. Creatine monohydrate's (Cr) ergogenic potential is well established; however fe...
Resistance Training for Explosive and Maximal Strength: Effects on Early and Late Rate of Force Development
Quadriceps muscle adaptation muscle strength peak torque power
2015/5/18
The aim of the present study was to verify whether strength training designed to improve explosive and maximal strength would influence rate of force development (RFD). Nine men participated in a 6-we...
