Brief Summary

This study explores the potential link between aerobic exercise combined with resistance training and improvements in cardiopulmonary function in obese individuals, focusing particularly on the influence of autonomic nerve function. By examining the effects of combined exercise on obese college students, this research aims to elucidate the critical role that autonomic nerve function improvement plays in enhancing cardiopulmonary function in this demographic.

The study primarily utilized a combined exercise regimen of aerobic and resistance exercises, conducted three times a week over a period of 16 weeks. One session was held during class hours, with the remaining two sessions scheduled during free time in the university gym. 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.

Study Groups

Experimental Group

30 participants underwent a 16-week program of aerobic (60%-70% HRmax for 40 minutes) and resistance exercises (65%-70% RM for 30 minutes).

Group Type: EXPERIMENTAL

Aerobic combined with Resistance exercise

Intervention Type: BEHAVIORAL

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.

Control Group

30 participants maintained normal physical activity without additional interventions.

Group Type: NO_INTERVENTION

No interventions assigned to this group
