Impact of Combined Aerobic and Resistance Exercise on Autonomic Function and Cardiopulmonary Endurance in Obese College Students

Participants are required to perform aerobic and resistance exercises. Aerobic exercises included the use of treadmills and elliptical machines, with intensity maintained at 60%-70% of the maximum heart rate (calculated as 220 minus age), for a total of 40 minutes per session (5 minutes of warm-up, 30 minutes of main exercise, and 5 minutes of cool-down). Heart rate monitors were used to ensure the intensity was maintained; resistance exercises involved gym equipment and bodyweight exercises, including the use of a pec deck machine, lat pull-downs, chest presses, bicep curls, tricep extensions, leg curls, and leg presses. The intensity of resistance exercises was set at about 65%-70% of one repetition maximum (1RM), with each session consisting of three sets of 6-8 repetitions and lasting for 30 minutes.
