Comparison of High-Intensity Interval Training and Medium-Intensity Interval Training in Athletes

High-Intensity Interval Training (HIIT) and Medium-Intensity Interval Training (MIIT) are popular training methods known for enhancing athletic performance. HIIT is characterized by short bursts of high-intensity exercise followed by brief recovery periods. This training approach typically involves exercising at 80-95% of maximum heart rate for intervals ranging from 20 seconds to a few minutes, followed by rest or lower-intensity activity. Moderate-Interval Training (MIIT), on the other hand, involves moderate-intensity exercise performed at 60-75% of maximum heart rate. The primary objective is to determine how HIIT and MIIT differ in improving CPF, strength, and agility among athletes. A randomized clinical trial will be conducted with a sample size of 80 athletes, divided into two groups. Participants will undergo 45-minute training sessions three times a week for six weeks, followed by pre- and post-intervention assessments using Cooper\'s 12-Minute Run/Walk Test, T-Test for agility, and Active Force 2 muscle tester for strength. Statistical analyses will be conducted to compare pre- and post-intervention results between the two groups, determining the significance of differences in CRF fitness, strength and agility outcomes.
