Sedentary Students, University Students
Conditions
Brief summary
This study aims to investigate the effects of a 6-week high-intensity interval training (HIIT) intervention on physical fitness, cardiorespiratory capacity (VO2max), and sleep quality among sedentary male college students. Through a randomized controlled trial, we seek to examine whether HIIT, as a time-efficient exercise modality, can effectively improve these health-related outcomes in young adults who maintain predominantly sedentary lifestyles. This research will provide evidence-based insights into the effectiveness of HIIT as a potential intervention strategy to address the physical and physiological consequences of prolonged sitting behavior among university students.
Interventions
A 6-week HIIT exercise plan (running). Duration: Each session consists of 10 x 1-minute high-intensity bouts interspersed with 10 x 1-minute recovery periods. Adding the 3-minute warmup and 3-minute cool-down, each session totals approximately 26 minutes. This protocol is followed for 6 weeks. Intensity: High-intensity bouts are performed at 80-90% of HRmax (RPE 15-18). Recovery periods are at 40-50% of HRmax (RPE 11-13). Warm-up and cool-down are at 50% HRmax (RPE 11-13). Modality: Running, jogging, or brisk walking, either on a treadmill or outdoors. Supervision: The first three sessions are supervised in a laboratory setting. Subsequent sessions are unsupervised and performed at home with heart rate monitoring and remote data tracking via Polar Flow for Coach.
