To determine the comparative effect of sports massage, active recovery, and rest on promoting blood lactate clearance after maximal anaerobic (supramaximal) leg exercise.
A counterbalanced experimental design with repeated measures was used. The repeated measures were the three treatment conditions. The order of the conditions was determined by random assignment to a counterbalanced test sequence. All data were collected in the Human Energy Research Laboratory at the University of Pittsburgh.
Ten male competitive cyclists volunteered for this investigation.
Serial venous blood samples were drawn and analyzed for blood lactate concentration for each test condition.
There were significant main effects for both absolute and relative values of blood lactate concentration between the three treatment groups and across time within groups.
After supramaximal leg exercise, active recovery produced significant decreases in both absolute and relative measures of blood lactate concentration when compared with the sports massage and rest conditions. No significant difference was found between sports massage and rest for either absolute or relative changes in blood lactate concentration.
比较运动按摩、主动恢复和休息对促进最大无氧(超最大)腿部运动后血乳酸清除的影响。
采用平衡实验设计和重复测量。重复测量为三种处理条件。条件的顺序由随机分配到平衡测试序列确定。所有数据均在匹兹堡大学人类能源研究实验室收集。
十名男性竞技自行车手自愿参加了这项研究。
对每个测试条件的静脉血样进行连续抽取和血乳酸浓度分析。
三组治疗组之间以及组内时间内的血乳酸浓度绝对值和相对值均有显著的主效应。
与运动按摩和休息条件相比,超最大腿部运动后,主动恢复可显著降低血乳酸浓度的绝对值和相对值。在血乳酸浓度绝对值和相对值的变化方面,运动按摩和休息之间没有发现显著差异。
