This study investigated the effects of a daily plyometric hopping intervention on running economy (RE) in amateur runners. In a randomized, controlled trial, thirty-four amateur runners (29 ± 7 years, 27 males) were allocated to a control or a hopping exercise group. During the six-week study, the exercise group performed 5 min of double-legged hopping exercise daily. To progressively increase loading, the number of hopping bouts (10 s each) was steadily increased while break duration between sets was decreased. Pre- and post-intervention, RE, peak oxygen uptake (VO), and respiratory exchange ratio (RER) were measured during 4-min stages at three running speeds (10, 12, and 14 km/h). ANCOVAs with baseline values and potential cofounders as cofactors were performed to identify differences between groups. ANCOVA revealed an effect of hopping on RE at 12 km/h (df = 1; F = 4.35; p < 0.05; η = 0.072) and 14 km/h (df = 1; F = 6.72; p < 0.05; η = 0.098), but not at 10 km/h (p > 0.05). Exercise did not affect VO (p > 0.05), but increased RER at 12 km/h (df = 1; F = 4.26; p < 0.05; η = 0.059) and 14 km/h (df = 1; F = 36.73; p < 0.001; η = 0.520). No difference in RER was observed at 10 km/h (p > 0.05). Daily hopping exercise is effective in improving RE at high running speeds in amateurs and thus can be considered a feasible complementary training program.Clinical trial registration German Register of Clinical Trials (DRKS00017373).
本研究旨在探讨每日增强式跳跃训练对业余跑者的跑步经济性（RE）的影响。采用随机对照试验设计，将 34 名业余跑者（29±7 岁，27 名男性）分为对照组和跳跃运动组。在为期六周的研究中，跳跃运动组每天进行 5 分钟的双腿跳跃练习。为了逐渐增加负荷，跳跃次数（每次 10 秒）稳步增加，而每组之间的休息时间则缩短。在干预前后，以 10、12 和 14km/h 的三个跑步速度进行 4 分钟阶段测量 RE、最大摄氧量（VO）和呼吸交换率（RER）。采用协方差分析（ANCOVA），以基线值和潜在混杂因素为协变量，比较两组之间的差异。ANCOVA 显示，跳跃运动对 12km/h（df=1；F=4.35；p<0.05；η=0.072）和 14km/h（df=1；F=6.72；p<0.05；η=0.098）的 RE 有影响，但对 10km/h 没有影响（p>0.05）。运动对 VO 没有影响（p>0.05），但增加了 12km/h（df=1；F=4.26；p<0.05；η=0.059）和 14km/h（df=1；F=36.73；p<0.001；η=0.520）的 RER。在 10km/h 时，RER 没有差异（p>0.05）。每日增强式跳跃训练可有效提高业余跑者在高速跑步时的 RE，因此可作为一种可行的补充训练方案。
