摘要

背景/目的评价塔克跳后休息间隔时间对10-s Wingate结果和反动作跳高的影响。方法阻力训练个体18例(男性10例，年龄21.3±3.6岁；女性：n = 8, 22.1±2.2岁)自愿参加四个阶段：熟悉、3分钟无跳跃休息间隔（CON）和两个随机实验阶段，在一系列塔克跳跃后休息间隔为1分钟（ER1）或5分钟（ER5）。在CON、ER1和ER5条件的基线（PRE）和后（POST）以及10-s Wingate循环测试中评估反向运动跳跃（CMJ）高度。测量温盖特相对峰值功率（RPP）和平均峰值功率（RMP）。单独的混合因子重复测量方差分析评估了不同条件和性别的Wingate变量的变化，以及条件、性别和时间对CMJ高度的影响，alpha值为p≤0.05。结果ER1组rpp和RMP分别显著高于CON组0.92±0.23 W kg - 1和0.41±0.14 W kg - 1， ER5组rpp和RMP分别显著高于CON组0.77±0.23 W kg - 1和0.36±0.10 W kg - 1。RPP与RMP相似(p >；0.05)。对于CMJ高度，只有性别的主要影响，男性比女性高31.3% （p = 0.002）。结论：在无氧运动前进行塔克跳可以提高运动表现达5分钟

Evaluation of rest interval following a series of tuck jumps on anaerobic performance

Background/objective

This study assessed the influence of rest interval duration after tuck jumps on 10-s Wingate outcomes and countermovement jump height.

Methods

Eighteen resistance trained individuals (males: n = 10, 21.3 ± 3.6 years; females: n = 8, 22.1 ± 2.2 years) volunteered to participate in four sessions: familiarization, 3-min rest interval with no jumps (CON), and two randomized experimental sessions with a rest interval of either 1-min (ER1) or 5-min (ER5) after a series of tuck jumps. Countermovement jump (CMJ) height was assessed at baseline (PRE) and after (POST) the CON, ER1, and ER5 conditions, and 10-s Wingate cycling testing. Wingate relative peak power (RPP) and mean peak power (RMP) were measured. Separate mixed-factorial repeated measures analyses of variance assessed changes across conditions and sex for the Wingate variables and conditions, sex, and time for CMJ height at an alpha of p ≤ 0.05.

Results

RPP and RMP were significantly greater than CON for ER1 by 0.92 ± 0.23 W kg⁻¹ and 0.41 ± 0.14 W kg⁻¹, respectively, and ER5 by 0.77 ± 0.23 W kg⁻¹ and 0.36 ± 0.10 W kg⁻¹, respectively. ER1 and ER5 RPP and RMP were similar (p > 0.05). For CMJ height, there was only a main effect for sex as males jumped higher than females by 31.3 % (p = 0.002).

Conclusion

Performing tuck jumps prior to anaerobic exercise may increase performance for up to 5-min
