Boone, JB, VanDusseldorp, TA, Feito, Y, and Mangine, GT. Relationships between sprinting, broad jump, and vertical jump kinetics are limited in elite, collegiate football athletes. J Strength Cond Res 35(5): 1306-1316, 2021-To evaluate the relationships and agreement in kinetics measured during a 10-yd sprint, a standing broad jump (SBJ), and a vertical jump (VJ), 73 collegiate football players (22.3 ± 0.8 years, 188 ± 7 cm, 113 ± 23 kg) volunteered for this cross-sectional study over a 3-year period. At the beginning of each athlete's off-season training phase and after a standard warm-up, each athlete completed 2-3 maximal trials of each test while tethered to a robotic, cable-resistance device (10-yd sprint and SBJ) or a linear position transducer (VJ alone). Force (N), velocity (m·s-1), and power (W) were measured during the first 2 steps, acceleration phase (units·step-1), and entire 10-yd sprint, and the entire SBJ and VJ. Spearman and partial correlations (controlling for stature) revealed small-to-moderate relationships (r = -0.30 to -0.34) between the second sprinting step and VJ force. Small negative relationships were also noted between sprinting and VJ force and power, but not when controlling for height. Agreement was determined by examining relationships between the differences in and averaged kinetics measured on each test. Trivial-to-small relationships (r < 0.29) were observed between sprinting (first step and 10-yd) and VJ velocity, and between VJ and SBJ velocity, although coefficient of variation (CV) ranged between 64 and 104%. All other relationships ranged from moderate-to-practically perfect with CVs exceeding 500%. Although some relationships exist between sprinting and jumping kinetics, their agreement is variable. These data suggest that coaches and athletes should not use one of these assessments in place of, or to predict performance in, the other assessments.
布恩、范杜塞尔多普、费托、扬和马金，精英大学生足球运动员的冲刺、跳远和垂直跳跃动力学之间的关系有限。《力量与调节研究杂志》35（5）：1306-1316，2021 年-为了评估在 10 码冲刺、站立跳远（SBJ）和垂直跳跃（VJ）中测量的动力学之间的关系和一致性，73 名大学生足球运动员（22.3±0.8 岁，188±7 厘米，113±23 公斤）在 3 年期间自愿参加了这项横断面研究。在每个运动员的淡季训练阶段开始时，在标准热身之后，每个运动员在与机器人、电缆阻力装置（10 码冲刺和 SBJ）或线性位置传感器（仅 VJ）连接的情况下完成了 2-3 次最大试验。在第一和第二冲刺阶段、加速阶段（单位·步-1）和整个 10 码冲刺期间，以及整个 SBJ 和 VJ 期间，测量力（N）、速度（m·s-1）和功率（W）。Spearman 和偏相关（控制身高）显示第二冲刺阶段和 VJ 力之间存在小到中等程度的关系（r=-0.30 到-0.34）。还注意到冲刺和 VJ 力和功率之间存在小的负相关，但当控制身高时则没有。通过检查每个测试中测量的动力学差异和平均值之间的关系来确定一致性。在冲刺（第一阶段和 10 码）和 VJ 速度之间，以及在 VJ 和 SBJ 速度之间观察到微不足道到小的关系（r<0.29），尽管变异系数（CV）在 64%到 104%之间。所有其他关系的范围从中等到几乎完美，CV 超过 500%。尽管冲刺和跳跃动力学之间存在一些关系，但它们的一致性是可变的。这些数据表明，教练和运动员不应将这些评估中的一项用于替代或预测另一项评估的表现。
