Abstract

This study com pared the metabolic rate following an exercise bout to the resting metabolic rate (RM R) established in pretesting procedures for twelve college age females. The only factor differentiating the groups was length o f the training period (one week, two weeks, four weeks, and five weeks). Training took place on a Bosch cycle ergometer three times a week, for 30 minutes each session, at 70 to 85 percent o f the subjects' heart rate reserve (HRR). Breath analysis was measured on a Beckman Metabolic Cart in both pretesting and post-testing procedures.

The findings indicated that aerobic exercise, performed at 70 to 85 percent o f the HRR for 30 minutes, elevated the individual's RMR for at least 90 minutes following the exercise. No statistically significant difference was observed in the acute elevation o f the RM R between the four groups; however, significant differences in the RM R occurred between subjects, regardless of group affiliation. Variables including workload, exercising heart rate, percentage of HRR utilized during the exercise sessions, and body fat were analyzed to determine their contribution to the elevated RMR levels. No statistical significance was found; however, it appeared that higher intensities and larger workloads increased the magnitude o f the excess post-exercise oxygen consumption.

It was concluded that aerobic exercise would prove beneficial for weight reduction programs; not only for the energy expended during the activity, but also for the extra energy utilized dining the recovery period.
