Verbal Encouragement in Swimming

Verbal encouragement (VE) is used to enhance the performance in several sports, even though no studies have been conducted in swimmers and no effects have been reported in elite athletes by some Authors. Besides influencing motor performance, VE is also known to enhance the physical load, thus increasing the probability of developing fatigue. The aim of this research was to study VE in swimmers by evaluating both chronometric performance and muscle fatigue (using sEMG).
