The ability of continuous lactate clearance and the inflection points of the lactate curve are two important determinants of performance of competitive field athletes. Current training practices for improving lactate tolerance such as high intensity aerobic activities and the combination of aerobic and resistance training seem to have undesired physiological adaptations (e.g. muscle loss, change in fiber types). The Role of Explosive power movements in lactate accumulation has not been studied properly. Hence, the purpose of this study was to assess lactate response after the completion of three different volume patterns of the power clean movement. Ten male recreational athletes (age 18-30 years) participated in the study. Volume patterns consisted of 3 sets* 3RM (I), 3 sets* 6RM (II) and 3 sets*9 RM (III) with identical rest periods of 2 minutes. Forty eight hours of rest observed between performances of each pattern. Blood samples were collected at the beginning and at the end of each volume pattern. The volume pattern of 3 sets * 9RM showed greatest post activity lactate response (7.43 mmol/l ±2.94mmol/l) as opposed to 4.03 mmol/l ± 1.78mmol/l and 5.27 mmol/l ±2.48mmol/ in patterns I and II respectively. Mean relative increase in lactate response was highest in volume III (356.34%). Findings indicate that lactate response in power cleans is largely associated with volume as determined by Number of repetitions, load, and rest interval. Explosive movements; if performed over a prolonged period can impose greater glycolytic and oxidative demands. This study presents the enticing proposition of evaluating the role of explosive power movements in improving lactate tolerance.
