目标
本研究的目的是评估不同的力量-功率测试与最大运行速度参数之间的关系。
方法
9名训练有素的男性在四个不同的场合接受了测试。第一次测量最大跑速度(MRV)、步频(SR)和步长(SL)，第二次在测力台上进行最大垂直跳跃(30、50和80 cm高度的纵跳[SJ]、立定跳远[SBJ]、反转跳跃[CMJ]和下坠跳跃[DJ])。在第3次实验中，使用与测力板相连的伸腿机测定伸腿肌的最大双侧等长力(MBIF)和用力时间特性(f-t10-30%、f-t10-60%和f-t10-90%)。在最后第四次，通过重复6秒最大周期冲刺来测量峰值无氧功率。计算了所有上述参数的皮尔逊积矩相关系数。
结果
相关系数显示，MRV与f-t10-60%和Dj30显著相关(r=-0.73和r=0.73，P均<0.05)。SR和SL与f-t10~60%呈显著正相关(r=-0.82，P<0.01和r=0.75，P<0.05)。
结论
目前的研究结果表明，快速产生力量的能力，以达到最大自愿收缩60%的时间来衡量，与短跑成绩有关，决定系数可解释数据方差的53%。这些数据还表明，短跑能力与DJ表现有关，尤其是从30厘米的高度跳跃。以上测试对短跑能力和短跑专项力量水平的准备和测试有一定的参考价值。
AIM
The aim of the present study was to assess the relationship between various strength-power tests and maximal running velocity parameters.
METHODS
Nine trained males were tested on four separate occasions. On the first occasion the maximum running velocity (MRV), stride rate (SR) and stride length (SL) were measured over 35 m. On the second occasion maximal vertical jumps (squat jump [SJ], standing broad jump [SBJ], counter movement jump [CMJ] and drop jumps [DJ] from heights of 30, 50 and 80 cm) were performed on a force platform. On the third occasion the maximal bilateral isometric force (MBIF) of leg extensors and the force time characteristics (f-t 10-30%, f-t 10-60% and f-t 10-90%) were determined using a leg extension machine connected to a force plate. On the final fourth occasion peak anaerobic power was measured via repeated 6 sec maximum cycle sprints. Pearson product-moment correlation coefficients were calculated for all the aformentioned parameters.
RESULTS
The correlation coefficients showed that MRV correlated significantly with f-t 10-60% and DJ 30 (r=-0.73 and r=0.73, P<0.05 respectively). In addition, SR and SL showed significant relationships with f-t 10-60% (r=-0.82, P<0.01 and r=0.75, P<0.05 respectively).
CONCLUSION
The present findings suggest that the ability to produce force quickly, as measured by the time to achieve 60% of maximum voluntary contraction is related to sprinting performance, with the coefficient of determination accounting for 53% of the variance in the data. These data also show that sprinting ability is linked with DJ performance, especially the drop jump from a height of 30 cm. It is suggested that the above tests may prove useful in preparing and testing the sprinting ability and sprint specific strength levels.
