Sprinting actions are related to decisive moments of the match and impose severe fatigue levels on football players, and are often preceded by lower intensity running patterns or walking on the field. This study aimed to compare the effects of different exercise drills on speed and acceleration dynamics. Forty Under-19 and Under-23 soccer players participated in different sprint drill conditions, quantifying their distance covered in various speed intensities covering high-speed running and sprinting patterns and their peak acceleration. The speed drills were compared across different conditions: LS30m (30 m Linear Sprint), LS40m (40 m Linear Sprint), 15BR + LS30m (15 m Bounding Run + 30 m Sprint), 15BR + LS40m (15 m Bounding Run + 40 m Sprint), and CS30m (30 m Chasing Sprint). The results of this study showed significant differences regarding maximal acceleration between the lowest value 15BR + LS30m (5.62 ± 0.83 m/s) and the highest, CS30m (7.09 ± 1.25 m/s; p = 0.001; d = - 0.88), as well as with LS30m (6.98 ± 1.43 m/s; p = 0.003; d = - 0.59), LS40m (6.76 ± 1.60 m/s; p = 0.002; d = - 0.69) drill. Regarding Sprint 3 distance (distance covered > 95% of maximal speed) significant differences were found between the highest, LS40m (2.42 ± 4.82 m) and the lowest 15BR + LS30m (0.0 ± 0.00; p = 0.057; d = - 0.52) as well LS30m (0.90 ± 3.31 m; p = 0.017; d = - 0.37) drill. These results suggest that the capacity to reach peak acceleration is mediated by how the athlete approaches the linear sprint. Moreover, the LS40m was observed to be a drill that successfully exposes the athlete to their peak speed compared to the LS30m and 15BR + 30 m drills. Therefore, it should be considered the use of LS40m drill for training prescriptions for developing speed or hamstring conditioning. Finally, the CS30m drill exposed the athletes to the highest peak acceleration, probably due to the visual stimulus provided by the opponent, which might have elicited higher levels of motivation for the chasing player. Briefly, in the LS40m, athletes cover more distance above 95% of maximum speed, while the CS30m seems to be more effective for achieving higher accelerations.
短跑动作与比赛的关键时刻相关,会给足球运动员带来极高的疲劳程度,并且通常在较低强度的跑步模式或在场上行走之后出现。本研究旨在比较不同训练方法对速度和加速动力学的影响。40名19岁以下和23岁以下的足球运动员参与了不同的短跑训练条件,对他们在各种速度强度下(包括高速奔跑和短跑模式)所覆盖的距离以及他们的峰值加速度进行了量化。对不同条件下的速度训练进行了比较:LS30m(30米直线短跑)、LS40m(40米直线短跑)、15BR + LS30m(15米跳跃跑 + 30米短跑)、15BR + LS40m(15米跳跃跑 + 40米短跑)和CS30m(30米追逐短跑)。本研究结果显示,最低值的15BR + LS30m(5.62±0.83米/秒)与最高值的CS30m(7.09±1.25米/秒;p = 0.001;d = -0.88)之间以及与LS30m(6.98±1.43米/秒;p = 0.003;d = -0.59)、LS40m(6.76±1.60米/秒;p = 0.002;d = -0.69)训练之间在最大加速度方面存在显著差异。关于短跑3距离(覆盖距离 > 最大速度的95%),最高值的LS40m(2.42±4.82米)与最低值的15BR + LS30m(0.0±0.00;p = 0.057;d = -0.52)以及LS30m(0.90±3.31米;p = 0.017;d = -0.37)训练之间存在显著差异。这些结果表明,达到峰值加速度的能力受运动员接近直线短跑的方式影响。此外,与LS30m和15BR + 30米训练相比,观察到LS40m训练能成功让运动员达到其峰值速度。因此,在制定发展速度或腘绳肌训练的处方时应考虑使用LS40m训练。最后,CS30m训练使运动员达到了最高的峰值加速度,可能是由于对手提供的视觉刺激,这可能激发了追逐运动员更高的动力水平。简而言之,在LS40m训练中,运动员在超过最大速度95%的情况下覆盖的距离更长,而CS30m训练似乎在实现更高加速度方面更有效。
