Myokine Identification Following Acute Exercise

Participants will take part in a VO2max test. This will include a graded exercise test (GXT) on a motorized treadmill while wearing a one-way, non-rebreathing valve and nose clip that allows for the evaluation of all expired air. Specifically, we will incorporate the Ellestad Protocol. The Ellestad Protocol is divided into 8 phases which gradually increases in speed and incline throughout the test. The VO2max test will continue until the participant reaches volitional fatigue defined by reaching a rate of perceived exertion (RPE) greater than 19 (using the Borg RPE Scale), OR a respiratory exchange ratio (RER) reaching above 1.1, OR a participant choosing to cease exercise for any reason.
