Abstract：
The study assessed conditioning activities\' (CAs\') effects involving different work-to-rest ratios (WRR) on taekwondo athletes\' physical performance. Adolescent taekwondo athletes (age: 16 ± 1 years) randomly participated in the control six experimental conditions. Each condition was composed of standard warm-up and CA composed of plyometrics (P) or repeated high-intensity techniques (RHIT) performed using three different WRR: 1:6, 1:7, self-selected rest time (SSRT). After rest, athletes performed countermovement jump (CMJ), taekwondo specific agility test (TSAT), 10 s frequency speed kick test (FSKT-10s), multiple frequency speed kick test (FSKT-mult). P1:7, SSRT induced techniques higher number in FSKT-10s (p < 0.001 for all comparisons) and lower TSAT time (p < 0.01 for all comparisons) compared with control. Kicks-number recorded during FSKT-mult was lower in the control compared with RHIT1:6 (p = 0.001), RHIT1:7 (p < 0.001), RHITSSRT (p < 0.05), P1:7 (p < 0.001), and SSRT (p < 0.001). Kicking decrement index (DI) during FSKT-mult was lower after RHIT1:6 compared with control (p = 0.008), RHIT1:7 (p = 0.031), P 1:6 (p = 0.014), PSSRT (p = 0.041). (1) P1:7 and PSSRT can be used to improve taekwondo-specific agility and kicks-number, (2) RHIT1:6 is beneficial to maintain low DI, and (3) plyometric and different WRR-repeated-techniques can enhance kicks-number.
摘要：
该研究评估了涉及不同作息比（WRR）对跆拳道运动员身体表现的调节活动（CA）影响。青少年跆拳道运动员（年龄：16±1岁）随机参加对照六个实验条件。每个条件由标准热身和CA组成，CA由使用三种不同的WRR：1：6、1：7，自我选择的休息时间（SSRT）进行的plyometrics（P）或重复的高强度技术（RHIT）组成。休息后,运动员进行了反运动跳跃（CMJ），跆拳道专项敏捷性测试(TSAT)，10s频率速度踢试验(FSKT-10s),多频率速度踢试验(FSKT-mult)。P1:7,与对照相比,SSRT诱导的技术在FSKT-10s中较高的数目(所有比较的p<0.001)和较低的TSAT时间(所有比较的p<0.01)。与RHIT1：6（p=0.001）相比，对照组在FSKT-mult期间记录的踢数更低，RHIT1：7（p<0.001），RHITSSRT（p<0.05），P1:7(p<0.001),和SSRT（p<0.001）。与对照相比，RHIT1:6后FSKT-mult期间的踢腿下降指数(DI)较低(p=0.008)，RHIT1：7（p=0.031），P1:6（p=0.014），PSSRT(p=0.041)。（1）P1：7和PSSRT可用于提高跆拳道特定的敏捷性和脚踢数，（2）RHIT1：6有利于保持低DI，(3)增重和不同的WRR重复技术可以提高踢次数。
