目标
本研究旨在确定在最大冲刺的整个加速阶段，传统的和特定于踝关节的垂直跳跃形式--蹲跳(SJ)、反动作跳跃(CMJ)、反弹-连续跳跃(RJ)、反弹-连续脚踝跳跃(AJ)所代表的力量-力量能力的需求相对于短跑加速能力的需求。
方法
19名男子短跑运动员进行了60米最大冲刺和各种垂直跳跃。计算了各阶段垂直跳跃成绩之间的相关系数，以及与60m冲刺成绩和各步冲刺加速度之间的相关系数。
结果
60m冲刺时间与SJ高度、CMJ高度、AJ高度和AJ指数有显著的相关性。AJ高度和指数与其他任何跳跃变量均无相关性。加速度在第6~10步与SJ高度呈显著正相关(r=0.48~0.51)，在第5~11步与CMJ高度呈显著正相关(r=0.46~0.54)。第14~19步AJ指数与加速度呈正相关(r=0.48~0.54)。在任何一步，加速度与RJ指数均无相关性。
结论
结果表明，与传统的跳跃模式相比，AJ可以评估不同的反应强度。为了有效地加速，SJ和CMJ的爆炸强度在加速的早期阶段(从6.6±0.4米到17.5±0.8米)是重要的，而以AJ代表的反应强度在加速的后期阶段(从23.4±1.0米到33.7±1.4米)是必要的。短跑运动员和教练员应该意识到有效加速对力量-力量能力的不同要求。
AIM
This study aimed to determine the demand of strength-power capabilities represented by traditional and ankle-specific vertical jump modalities ‑ squat jump (SJ), counter-movement jump (CMJ), rebound-continuous jump (RJ), rebound-continuous ankle jump (AJ) ‑ relative to sprint acceleration ability during the entire acceleration phase of maximal sprint.
METHODS
Nineteen male sprinters performed a 60-m maximal sprint and various vertical jumps. Correlation coefficients among the vertical jump performances and between those and the 60-m sprint time and sprint acceleration at each step were calculated.
RESULTS
There were significant relationships between the 60-m sprint time and SJ height, CMJ height, AJ height, and AJ index. AJ height and index had no correlation with any other jump variables. Acceleration was significantly correlated with SJ height from the 6th to the 10th steps (r=0.48-0.51) and with CMJ height from the 5th to the 11th steps (r=0.46-0.54). Acceleration was also correlated with the AJ index from the 14th to the 19th steps (r=0.48-0.54). Acceleration had no correlation with the RJ index at any step.
CONCLUSION
The results suggest that the AJ allows assessment of different reactive strengths compared with traditional jump modalities. To accelerate effectively, the explosive strengths of the SJ and CMJ are important during the early stage of acceleration (from 6.6±0.4 to 17.5±0.8 m), and the reactive strength represented by the AJ is necessary during the later stage of acceleration (from 23.4±1.0 to 33.7±1.4 m). Sprinters and coaches should be aware of the different demands of strength-power capability for effective acceleration.
