Abstract/OtherAbstract:
ABSTRACT: The ability to metabolize or tolerate lactate and produce power simultaneously can be important determinant of performance. Current training practices for improving lactate utilization include high intensity aerobic activities or a combination of aerobic and resistance training. Excessive aerobic training may have undesired physiological adaptations (e.g. muscle loss, change in fiber types). The role of explosive power training in lactate production and utilization needs further clarification. We hypothesized that high volume explosive power movements such as Olympic lifts can increase lactate production and overload lactate clearance. Hence, the purpose of this study was to assess lactate accumulation after the completion of three different volume patterns of power cleans. Ten male recreational athletes (age- 24.22 ± 1.39 y)volunteered. Volume patterns consisted of three sets* three maximum repetitions (3RM) (Low Volume, LV), three sets* six reps at 80%-85% of 3RM (Mid Volume, MV) and three sets* nine reps at 70%-75% of 3RM (High Volume, HV). Rest period was identical at two minutes. Blood samples were collected immediately before and after each volume pattern. HV resulted in the greatest lactate accumulation (7.43 mmol/l ±2.94mmol/l) vs. (5.27 mmol/l ±2.48mmol/l and 4.03 mmol/l ± 1.78mmol/l in MV and LV, respectively). Mean relative increase in lactate was highest in HV (356.34%). Findings indicate that lactate production in power cleans is largely associated with volume, determined by number of repetitions, load, and rest interval. High volume explosive training may impose greater metabolic demands than low volume explosive training and may improve ability to produce power in the presence of lactate. The role of explosive power training in overloading the lactate clearance mechanism should be examined further, especially for athletes of intermittent sport.
