The aim of this study was tο examine the acute responses to an Ultra-Short Race Pace Training (USRPT) and a High-Intensity Interval Training (HIIT), both oriented for the event of 100 m freestyle. Eighteen national-level swimmers (8 boys, 10 girls) aged 13.5 ± 0.1 years, with 8.0 ± 0.5 years of experience participated in the study. All participants completed a USRPT and a HIIT protocol consisting of 2 × 10 × 25 m (USRPT1 & USRPT2) and 5 × 50 m. Significantly higher swimming velocity (SV) were achieved in USRPT compared to HIIT ( < 0.001), while significantly lower distance per stroke (DPS) and stroke index (SI) were obtained ( = 0.007 and < 0.001). Also, significantly lower blood lactate and glucose (BL & BG) concentrations were found after USRPT ( ≤ 0.001 and = 0.037). Heart rate (HR) and rate of perceived exertion (RPE) were significantly lower after USRPT than HIIT ( < 0.001 and = 0.015). According to the results, an USRPT swimming set consisting of 20 × 25 m at a 100 m pace seems to induce more specific responses in kinematic characteristics, biomarkers, HR and RPE compared to a 5 × 50 m HIIT set.
本研究的目的是检验针对100米自由泳项目的超短距离比赛配速训练（USRPT）和高强度间歇训练（HIIT）的急性反应。18名年龄为13.5±0.1岁、有8.0±0.5年游泳经验的国家级游泳运动员（8名男孩，10名女孩）参与了该研究。所有参与者都完成了一项USRPT和一项HIIT方案，分别包括2×10×25米（USRPT1和USRPT2）以及5×50米。与HIIT相比，USRPT的游泳速度（SV）显著更高（<0.001），而每划距离（DPS）和划水指数（SI）显著更低（分别为=0.007和<0.001）。此外，USRPT后血乳酸和血糖（BL&BG）浓度显著更低（≤0.001和=0.037）。USRPT后的心率（HR）和主观用力感觉等级（RPE）显著低于HIIT（<0.001和=0.015）。根据研究结果，与5×50米的HIIT组相比，由20×25米、按100米配速组成的USRPT组似乎能在运动学特征、生物标志物、心率和主观用力感觉等级方面引发更具针对性的反应。
