Measuring the hydrodynamic profiles of swimmer’s

A hydrodynamic profile, which is primarily composed of drag force, effects a swimmer’s performance; therefore, coaches, swimmers and sports analysts are keenly interested in the components of drag. Drag force is effected by intrinsic properties of water and the swimmer, decreasing acceleration. Drag is composed of active and passive drag. Passive drag, the focus of…

How much does visual distraction effect torso position in side-stepping

side stepping

An important steering task in team sports is cutting and side-stepping (SS), a maneuver performed to evade oncoming opponents. Sidestepping during game situations is complex, as athletes are generally traveling at higher velocities and often required to sidestep under unpredictably high temporal constraints when responding to opponents’ defensive movements or other situational demands. Frontal plane…

Technical difference’s in Volleyball players show shoulder anatomical adaptation


In elite volleyball players, repetitive spiking unevenly burdens the (DOM) dominant shoulder, which can result in adaptations or injuries. Spiking consists of the cocking, acceleration and deceleration phases. In the cocking phase, the dominant arm abducts and externally rotates in preparation for forceful adduction and internal rotation in the acceleration phase. Finally, the hand decelerates…
