Key result
Ultra-Short Race Pace Training (USRPT) achieved significantly higher swimming velocity (p<0.001) and lower blood lactate, heart rate, and perceived exertion compared to HIIT in competitive swimmers.
Why the study?
The study was conducted to examine acute responses to Ultra-Short Race Pace Training compared to High-Intensity Interval Training, both oriented for the 100 m freestyle event.
Does Ultra-Short Race Pace Training (USRPT) induce different acute physiological and kinematic responses compared to High-Intensity Interval Training (HIIT) in young competitive swimmers?

p-value: p=<0.001
USRPT induces more specific kinematic and physiological responses at a 100 m pace compared to HIIT in young competitive swimmers.
Acute velocity gains with USRPT in youth swimmers may inform session design; leaves open optimal long-term programming and transfer to competition.
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 (p < 0.001), while significantly lower distance per stroke (DPS) and stroke index (SI) were obtained (p = 0.007 and p < 0.001). Also, significantly lower blood lactate and glucose (BL & BG) concentrations were found after USRPT (p ≤ 0.001 and p = 0.037). Heart rate (HR) and rate of perceived exertion (RPE) were significantly lower after USRPT than HIIT (p < 0.001 and p = 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.

Papadimitriou et al. (2023) studied Competitive swimmers (n=18). Ultra-Short Race Pace Training (USRPT) vs. High-Intensity Interval Training (HIIT) was evaluated on swimming velocity (SV) (p=<0.001). Ultra-Short Race Pace Training (USRPT) achieved significantly higher swimming velocity (p<0.001) and lower blood lactate, heart rate, and perceived exertion compared to HIIT in competitive swimmers.
