An Active Recovery (AR) during a 10-s sprint may induce physical adaptation.<br> <strong>Objectives. </strong>This study compares the effect of 20% and 40% VO2peak AR during SIT on aerobic and anaerobic capacity.<br> <strong>Methods. </strong>Twelve healthy students participated in the study. They were randomly assigned to one of two groups: 20% active recovery group (ARG) and 40% ARG. Both groups performed a series of 10-s SIT separated by 4 minutes of AR. The sprints progressed from 4 to 6 over six sessions, separated by 2 days of rest. 20-ARG performed AR at 20%. VO2peak (average VO2 from the last 15 seconds of the incremental exercise test), 40-ARG performed AR at 40% of VO2peak. Aerobic and anaerobic capacity were measured before and after training.<br> <strong>Results. </strong>There was no significant difference in VO2peak and maximal incremental power output (Pmax) between 20-ARG and 40-ARG. VO2peak of 20-ARG was significantly increased from pre-training (p=0.004, &eta;2=0.589), whereas VO2peak of 40-ARG increased but was not significantly different. Pmax from both groups was significantly higher than pre-training (p=0.000, &eta;2=0.758). The relative leg strength in 20-ARG was significantly increased from pre-training (p=0.020, &eta;2=0.431). Anaerobic capacity and reproducibility of power output during training were not significantly different between groups or over time. AR at 20% or 40% VO2peak caused similar training effects and reproducibility of power during training.<br> <strong>Conclusion.</strong> Practitioners can prescribe a 10-s Wingate-based SIT with low-intensity active recovery to enhance aerobic performance and muscle strength in healthy undergraduate students.</div> Sprint Interval Training, Active Recovery, Aerobic, Anaerobic, Capacity 0 0 http://aassjournal.com/browse.php?a_code=A-11-2374-2&slc_lang=en&sid=1 Supattra Silapabanleng Supattra.s@allied.tu.ac.th 100319475328460017250 100319475328460017250 No Department of Sports Science and Sports Development, Faculty of Allied Health Sciences, Thammasat University, 12120, Thailand Sairag Saadprai sairag.saa@allied.tu.ac.th 100319475328460017251 100319475328460017251 No Department of Sports Science and Sports Development, Faculty of Allied Health Sciences, Thammasat University, 12120, Thailand Vinitha Puengtanom vinitha.p@allied.tu.ac.th 100319475328460017252 100319475328460017252 No Department of Sports Science and Sports Development, Faculty of Allied Health Sciences, Thammasat University, 12120, Thailand Supasin Wilaskhampee Suparsin.vil@dome.tu.ac.th 100319475328460017253 0009-0004-3283-6002 No Department of Sports Science and Sports Development, Faculty of Allied Health Sciences, Thammasat University, 12120, Thailand Piriya Suwondit piriya.s@allied.tu.ac.th 100319475328460017254 0009-0003-3513-712X Yes Department of Sports Science and Sports Development, Faculty of Allied Health Sciences, Thammasat University, 12120, Thailand
