Abstract
The energy cost of performing 1 and 3 sets of strength-type (6-8 RM) and endurance-type (30-35 RM) bench press exercise was estimated by indirect calorimetry in 10 male college students.
The total net energy cost of performing 3 sets of endurance-type resistive exercise (20.57 ± 1.86 kcal) was significantly (p <.05) greater than strength-type resistive exercise (15.24 ± 1.51 kcal) (mean ± SEM). Results were similar when energy cost was expressed relative to lean body mass. However, when expressed relative to the amount of work performed (kcal•kgm-1) the strength-type exercise (2.35 ± 0.19) resulted in a significantly (p <.05) greater expenditure of energy than did endurance-type exercise (1.64 ± 0.30). The energy cost relative to work performed was found to be significantly greater for 1 set of strength-type exercise than for any other condition (p <.05). The relationship between the energy cost of 1 set, multiplied by 3, and 3 sets was r=0.64 for endurance-type exercise and r=0.27 for strength-type exercise.
It was concluded that compared to strength-type resistive exercise, endurance-type resistive exercise requires a greater net energy expenditure. The results suggest that endurance-type exercise be performed by individuals who wish to expend the greatest amount of energy during resistive exercise. Although a poor relationship was found between the energy cost of performing 1 set (x3) and 3 sets of resistive exercise, conclusions must await further study with larger sample sizes.
Additional research is needed to define the importance of the exercise:rest ratio including the possible effects of prior exercise, potential differences in utilization of energy substrates, and the influence of training on the energy cost of resistive exercise.
