Abstract:   
Background. Wingate-based sprint interval training (SIT) is effective in enhancing aerobic and anaerobic fitness. An Active Recovery (AR) during a 10-s sprint may induce physical adaptation.
Objectives. This study compares the effect of 20% and 40% VO2peak AR during SIT on aerobic and anaerobic capacity.
Methods. 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.
Results. 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, η2=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, η2=0.758). The relative leg strength in 20-ARG was significantly increased from pre-training (p=0.020, η2=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.
Conclusion. 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.
