We hypothesized that stair-jump exercise would induce less muscle damage and greater acute metabolic responses than level-jumps.
Trained males executed 100 unilateral jumps on stairs with one leg, and at level with the other leg, with two weeks hiatus. Maximal isometric voluntary torque (MVC) and rate of torque development (RTD)in the quadriceps, and unilateral vertical jump height (VJ) were determined in the trained leg at pre-exercise,immediately at post- (IP), 24 h and 48 h after exercise. Serum creatine kinase (CK) level and delayed onset muscle soreness (DOMS) were evaluated at pre-exercise, 24 h and 48 h. Acute lactate and heart rate responses were also measured.
Lactate and heart rate at IP increased similarly under the two conditions. CK was elevated and MVC was depressed while RTD and VJ remained unchanged at 24 h in both types of training. MVC recovered at 48 h only after stair-jump exercise. DOMS developed only after level-jumps. Except DOMS, no effects of condition were found in any other variables.
We conclude that vigorous stair-jump exercise highly stresses the aerobic and the anaerobic energy system, and it preserves power and rapid torque generating ability 24 h after exercise. Stair-jump could be one alternative exercise to prevent muscle soreness.
我们假设，与水平跳跃相比，阶梯跳跃运动引起的肌肉损伤更少，急性代谢反应更大。
受过训练的男性单腿在楼梯上进行100次单侧跳跃，另一条腿在平地上进行，中间间隔两周。在运动前、运动后即刻（IP）、运动后24小时和48小时测定训练腿股四头肌的最大等长随意扭矩（MVC）和扭矩发展速率（RTD），以及单侧垂直跳跃高度（VJ）。在运动前、24小时和48小时评估血清肌酸激酶（CK）水平和延迟性肌肉酸痛（DOMS）。还测量了急性乳酸和心率反应。
两种条件下，运动后即刻的乳酸和心率升高情况相似。两种训练类型在24小时时，CK均升高，MVC降低，而RTD和VJ保持不变。仅在阶梯跳跃运动后，48小时时MVC恢复。仅在水平跳跃后出现DOMS。除DOMS外，在任何其他变量中均未发现条件效应。
我们得出结论，剧烈的阶梯跳跃运动对有氧和无氧能量系统有高度压力，并且在运动后24小时能保持力量和快速扭矩产生能力。阶梯跳跃可能是预防肌肉酸痛的一种替代运动。
