Effects of Different High-Intensity Interval Training Protocols on Physiological and Skeletal Muscle Adaptations in Healthy Young Men
This study investigated the effects of different high-intensity interval training protocols on physical fitness and physiological adaptations in healthy young men.
Participants underwent a two-week exercise training program consisting of six sessions performed three times per week. Four training protocols were investigated, differing in exercise intensity, duration of exercise bouts, and recovery periods.
The primary outcome was the change in maximal oxygen uptake (VO2max), an indicator of aerobic fitness. Additional assessments included cognitive performance, measured using tests of attention, processing speed, and inhibitory control, as well as selected physiological and skeletal muscle adaptations.
The study aimed to improve understanding of how different high-intensity interval training protocols influence aerobic fitness and other physiological responses over a short training period.

상세 설명
High-intensity interval training (HIIT) and sprint interval training (SIT) are exercise strategies characterized by repeated bouts of vigorous or maximal exercise interspersed with recovery periods. These training approaches may induce physiological adaptations within relatively short intervention periods. However, the effects of different combinations of exercise duration, intensity, and recovery time on aerobic fitness, cognitive performance, and skeletal muscle adaptations require further investigation.
This interventional study examined physiological responses to four cycling-based high-intensity training protocols in healthy young men. Participants completed six training sessions over two weeks, with three sessions performed each week.
The investigated protocols included:
SIT10:1: Repeated 10-second maximal cycling sprints separated by 60-second recovery periods.
SIT10:4: Repeated 10-second maximal cycling sprints separated by 240-second recovery periods.
HIIT90:180: Six 90-second cycling intervals performed at 80% of maximal aerobic power, separated by 180-second passive recovery periods.
Wingate-SIT: Repeated 30-second all-out cycling sprints using a Wingate-based protocol.
The primary outcome was the change in maximal oxygen uptake (VO2max), assessed using incremental exercise testing before and after the intervention. Additional assessments included cognitive performance using the Stroop Color-Word Test, Trail Making Test, and Digit Span Test, as well as selected measures of exercise performance and skeletal muscle metabolic adaptations.
Skeletal muscle biopsies were collected from subsets of participants before and after training to investigate exercise-induced adaptations in muscle tissue. Stored biopsy samples were subsequently used for exploratory proteomic analyses.
The study was designed to characterize short-term physiological and skeletal muscle responses to different high-intensity interval exercise protocols.
