Recently, Nasirzade et al. (2013) demonstrated the relative contribution of different architectural parameters such as fascicle length and muscle thickness of vastus
lateralis from different biomechanical, anthropometrical,
and muscle architectural parameters in predicting 50-m
sprint front crawl swimming performance in young male
swimmers. Although there has not been another study to
examine these parameters in swimmers, the results of
similar studies on athletes that required high muscle
power production such as sprinting demonstrated that
sprinters compared to endurance runners and untrained
individuals have greater fascicle in their locomotor muscles
