Summary

Aims

The purpose of this study was to compare the effects of high-intensity interval training (HIT) program on maximal oxygen uptake (VO_2max), first ventilatory threshold (VT₁) and second (VT₂), 3000-m running time (3000-m RT), peak power output (PPO) and mean power output (MPO) in physically active and inactive men.

Methods

Twelve healthy young inactive men (age = 19.1 卤 1 years) and 12 collegiate soccer players (age = 19.4 卤 1 years) volunteered for this study. Each training session involved a 10 min warm-up followed by a HIT program consisting of 6-10, 30 s all-out sprints with a 4 min recovery. A 5 min cool down period was then performed. This regiment was done three times per week for eight consecutive weeks.

Results

Significant improvements (P < 0.05) were found in VO_2max (7.6%), VT₁ (4.5%), VT₂ (4.2%), 3000-m RT (鈭?.4%), PPO (8.3%) and MPO (10.9%) following the HIT program in the active group. We showed significant improvements (P < 0.05) in VO_2max (13.7%), VT₁ (3.8%), VT₂ (3.8%), 3000-m RT (鈭?.8%), PPO (14.6%) and MPO (19%) following the HIT program among inactive subjects. The inactive group exhibited greater improvements in VO_2max (P 鈮?#xA0;0.05), PPO (P 鈮?#xA0;0.05) and MPO (P 鈮?#xA0;0.01) than the active group. In conclusion, greater improvement was observed in the inactive subjects, despite greater maximal values in the active group.
