Summary

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.

Interventions

OTHER

High Intensity Training (Group A)

Each 45-minute session will begin with a 5-minute warm-up consisting of dynamic stretches targeting major muscle groups. The main workout will include high-intensity cardio intervals, strength exercises, and agility drills, such as sprints, jump squats, and ladder drills, performed in short bursts with brief rest periods. The session will end with a cool-down phase of static stretching to support recovery and flexibility.

OTHER

Medium Intensity Training (Group B)

Each 45-minute session will start with a 5-minute warm-up of dynamic stretches. The main workout will start with moderate-paced cardio intervals, strength exercises, and agility drills, such as jogging, bodyweight squats, and cone drills, allowing for steady effort with manageable rest intervals. The session will end with a cool-down phase of static stretching to promote muscle recovery and flexibility.
