Session ratings of perceived exertion (session RPE) are commonly used to assess global training intensity for team sports. However, there is little research quantifying the intensity of field-based training protocols for speed development. The study's aim was to determine the session RPE of popular training protocols (free sprint [FST], resisted sprint [RST], and plyometrics [PT]) designed to improve sprint acceleration over 10 m in team sport athletes. Twenty-seven men (age = 23.3 ± 4.7 years; mass = 84.5 ± 8.9 kg; height = 1.83 ± 0.07 m) were divided into 3 groups according to 10-m velocity. Training consisted of an incremental program featuring two 1-hour sessions per week for 6 weeks. Subjects recorded session RPE 30 minutes post training using the Borg category-ratio 10 scale. Repeated measures analysis of variance found significant (p < 0.05) changes in sprint velocity and session RPE over 6 weeks. All groups significantly increased 0- to 5-m velocity and 0- to 10-m velocity by 4-7%, with no differences between groups. There were no significant differences in session RPE between the groups, suggesting that protocols were matched for intensity. Session RPE significantly increased over the 6 weeks for all groups, ranging from 3.75 to 5.50. This equated to intensities of somewhat hard to hard. Post hoc testing revealed few significant weekly increases, suggesting that session RPE may not be sensitive to weekly load increases in sprint and plyometric training programs. Another explanation, however, could be that the weekly load increments used were not great enough to increase perceived exertion. Nonetheless, the progressive overload of each program was sufficient to improve 10-m sprint performance. The session RPE values from the present study could be used to assess workload for speed training periodization within a team sports conditioning program.
运动中常用分段感觉用力（session RPE）评估来评估整体训练强度，但很少有研究量化针对速度发展的基于场地训练方案的强度。本研究旨在确定提高团队运动运动员 10 米冲刺加速能力的几种流行训练方案（自由冲刺 [FST]、抗阻冲刺 [RST]和增强式训练 [PT]）的分段感觉用力值。27 名男性（年龄=23.3±4.7 岁；体重=84.5±8.9kg；身高=1.83±0.07m）根据 10 米速度分为 3 组。训练包括一个递增方案，每周进行 2 次 1 小时的训练，共 6 周。受试者在训练后 30 分钟使用 Borg 10 级比例量表记录分段感觉用力值。重复测量方差分析发现，6 周内冲刺速度和分段感觉用力值均有显著变化（p＜0.05）。所有组在 0 至 5 米和 0 至 10 米速度上均有 4-7%的显著提高，组间无差异。各组间的分段感觉用力值无显著差异，表明方案强度匹配。6 周内所有组的分段感觉用力值均显著增加，范围从 3.75 到 5.50，相当于有些吃力到吃力的程度。事后检验显示每周增加量很少有显著差异，表明分段感觉用力值可能对冲刺和增强式训练方案的每周负荷增加不敏感。然而，另一种解释可能是每周使用的负荷增量不够大，无法增加感知用力。尽管如此，每个方案的渐进性超负荷足以提高 10 米冲刺表现。本研究的分段感觉用力值可用于评估团队运动训练计划中速度训练分期的工作量。
