The objective of the present research was to compare the effect of the sequence of concurrent strength and endurance exercises on the freestyle tumble turn. Forty male subjects between the ages of 15 and 19 years, with at least two years of competitive swimming experience, volunteered to participate in the study. The average age of 17.22 ± 0.94 years, 169.62 ± 7.11 Cm of height, and 62.82 ± 7.78 Kg of body mass were randomly chosen and divided into five groups of eight subjects – i.e. strength training (ST), endurance training (ET), strength-endurance training (SE), endurance-strength training (ES) and control (CO). The analyzed variables were the time duration, in seconds, of each turn phase: rolling time (RT), wall contact time (WCT), pushing time (PT), gliding time (GD) and 5 m round trip time (5mRTT) were calculated for each subject. There was the significant of the strength training on the 5mRRT and WCT. There were no significant changes in other training on the each turn phase.
