ClinConnect Summary

This clinical trial is studying how the number of times a week people exercise affects their fitness improvements. Specifically, it looks at healthy university students and aims to find out whether exercising two, three, or four times a week makes a difference in their cardiorespiratory fitness, which is an important measure of how well the heart and lungs work together during physical activity. Participants will start with a fitness test, then be divided into four groups: one that exercises two days a week, another that trains three days a week, a third that trains four days a week, and a control group that will not exercise at all. After four weeks of training, everyone will take the fitness test again to see how much they have improved.

To be eligible for this study, participants should be recreationally active, meaning they exercise at least two to three days a week but have not been part of a regular training program for the last three months. People who smoke, take certain supplements that can affect metabolism, or do not meet the activity requirements will not be included in the study. If you choose to participate, you can expect to engage in short, intense sprint workouts with breaks in between, while helping researchers learn more about how exercise frequency can boost fitness levels.
