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

Pakistan36 participantsStarted 2025-03-21

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
