Attention all English speaking, healthy, physically active but not training individuals between the ages of 18 to 40 years!

Are you looking to improve your cardiovascular fitness and leg power? Participate in our research study to investigate the acute effects of different intensities of 4-s sprint interval exercise on physiological responses and determine the relationship between intensity and recovery duration.

By joining this research study, you will be asked to attend 11 laboratory visits including 10 exercise sessions in 5 weeks (2-3 times per week), with a 24-hour resting interval between each session. Don't worry, you can schedule the exercise sessions at your convenience, and the total time commitment is only 11 hours.

We understand that safety is a top priority, and all procedures have been proven to be safe with minimal discomfort. You may experience some fatigue after the exercise sessions, but this feeling subsides soon after completion. As for risks, you may feel some pain at your fingertip when we obtain a small blood sample for blood lactate measurements, and there is a small possibility of bruising, light-headedness, dizziness, fainting, or infection associated with drawing blood from a vein.

The possible benefits of this research study include increased cardiovascular fitness and leg power, as well as results from the VO2peak test and maximal cycling power. Participation is entirely voluntary, and you can stop at any time. Don't miss out on this opportunity to improve your fitness and contribute to science!
