The rate of force development (RFD) is an essential component for performance in explosive activities, although it has been proposed that muscle architectural characteristics might be linked with RFD and power performance. The purpose of the study was to investigate the relationship between RFD, muscle architecture, and performance in young track and field throwers. Twelve young track and field...

BACKGROUND Several studies have demonstrated that body habitus is associated with survival (life expectancy) time. We sought to determine if survival differed between elite athletes with a range of body types. We hypothesized that the survival would differ between athlete types and that ectomorph athletes would have longer survival than heavier athletes. METHODS For each Olympics between 1928...

Internal impingement is a term used to describe the pathologic contact of the undersurface of the rotator cuff with the glenoid. It typically occurs in overhead athletes, particularly throwers. In these athletes, the bones and soft tissues adapt to allow these athletes to have a supraphysiologic range of motion. In many athletes, these changes may lead to symptoms of internal impingement. This ...

The article reveals the peculiarities of development physical qualities by means athletics. It was determined that education at current stage society plays an important role in formation personality, and process its popularization among younger generation is complicated insufficient interest students generally accepted forms conducting practical classes on one hand overloading educational progr...

This study investigated how the human CNS organizes complex three-dimensional (3D) ball-throwing movements that require both speed and accuracy. Skilled baseball players threw a baseball to a target at three different speeds. Kinematic analysis revealed that the fingertip speed at ball release was mainly produced by trunk leftward rotation, shoulder internal rotation, elbow extension, and wrist...

When the shot is released above a horizontal plane, range from this point depends on release height, speed and angle. Measured distance is the sum of this range and horizontal distance of the release point from the throwing circle edge. Optimal release conditions can be calculated only if the dependence of release velocity on other variables, due to thrower limitations, is known. Experiments on...
