Athletes are often required to undertake multiple training sessions on the same day with these sessions needing to be sequenced correctly to allow the athlete to maximize the responses of each session. We examined the acute effect of strength and speed training sequence on neuromuscular, endocrine, and physiological responses over 24h.
15 academy rugby union players completed this randomized crossover study.
Players performed a weight training session followed 2h later by a speed training session (weights speed) and on a separate day reversed the order (speed weights). Countermovement jumps, perceived muscle soreness, and blood samples were collected immediately prior, immediately post, and 24h post-sessions one and two respectively. Jumps were analyzed for power, jump height, rate of force development, and velocity. Blood was analyzed for testosterone, cortisol, lactate and creatine kinase.
There were no differences between countermovement jump variables at any of the post-training time points (p>0.05). Likewise, creatine kinase, testosterone, cortisol, and muscle soreness were unaffected by session order (p>0.05). However, 10m sprint time was significantly faster (mean±standard deviation; speed weights 1.80±0.11s versus weights speed 1.76±0.08s; p>0.05) when speed was sequenced second. Lactate levels were significantly higher immediately post-speed sessions versus weight training sessions at both time points (p<0.05).
The sequencing of strength and speed training does not affect the neuromuscular, endocrine, and physiological recovery over 24h. However, speed may be enhanced when performed as the second session.
运动员常常需要在同一天进行多次训练，且这些训练需要正确排序，以使运动员能够最大限度地从每次训练中获得收益。我们研究了力量和速度训练顺序对24小时内神经肌肉、内分泌和生理反应的急性影响。
15名学院英式橄榄球联盟球员完成了这项随机交叉研究。
球员先进行一次重量训练，2小时后进行一次速度训练（先重量后速度），在另一天则颠倒顺序（先速度后重量）。分别在每次训练前、训练后即刻以及训练后24小时采集反向移动跳、肌肉酸痛感知和血样。分析跳跃的功率、跳跃高度、力量发展速率和速度。分析血液中的睾酮、皮质醇、乳酸和肌酸激酶。
在任何训练后时间点，反向移动跳变量之间均无差异（p>0.05）。同样，肌酸激酶、睾酮、皮质醇和肌肉酸痛均不受训练顺序的影响（p>0.05）。然而，当速度训练排在第二位时，10米短跑时间显著更快（平均值±标准差；先速度后重量为1.80±0.11秒，先重量后速度为1.76±0.08秒；p>0.05）。在两个时间点，速度训练后即刻的乳酸水平均显著高于重量训练后即刻（p<0.05）。
力量和速度训练的顺序不影响24小时内的神经肌肉、内分泌和生理恢复。然而，当速度训练作为第二次训练时，速度可能会提高。
