Modern competitive sport has evolved so much that athletes would go to great extremes to
develop themselves into champions; medicine has also evolved to the point that many …

Training variants (type, intensity, and duration of exercise) can be selected according to
individual aims and fitness assessment. Recently, various methods of resistance and …

Objective: The ACTN3 R577X gene variant results in the absence of the α-actinin-3 protein
in∼ 18% of humans worldwide and has been associated with athletic performance and …

Heritability studies on sport-related traits accepted that endurance, speed, power, and
strength abilities include an active genetic predisposition to elite soccer participation. This …

Many causes define injuries in professional soccer players. In recent years, the study of
genetics in association with injuries has been of great interest. The purpose of this study was …
