Comparing the energy expenditure and rating of perceived exertion of various exercise modes at a specific heart rate.

Comparing the energy expenditure and rating of perceived exertion of various exercise modes at a specific heart rate. - 50 p.

Aerobic exercise is one of the key elements for the elimination of obesity, which is a national health problem. Presently, there is limited research on energy expenditure and rating of perceived exertion (RPE) when comparing the elliptical machine, treadmill, and cycle ergometer. The purpose of this study was to compare the energy expenditure, oxygen uptake, and RPE of various modes of exercise at three specific heart rates (100 bpm, 130 bpm, and 160 bpm).

520 $a Aerobic exercise is one of the key elements for the elimination of obesity, which is a national health problem. Presently, there is limited research on energy expenditure and rating of perceived exertion (RPE) when comparing the elliptical machine, treadmill, and cycle ergometer. The purpose of this study was to compare the energy expenditure, oxygen uptake, and RPE of various modes of exercise at three specific heart rates (100 bpm, 130 bpm, and 160 bpm).
520 $a Twenty healthy, recreationally active men and women between the ages of 18 and 29 participated in this randomized, two-week study. While exercising, participants were connected to a metabolic cart to measure metabolic responses and wore a Polar heart rate monitor to record heart rate. Participants completed all three exercise trials in random order. During each exercise test trial, they started slowly to keep their heart rate at 100 bpm and remained at a steady state for energy expenditure, oxygen uptake, and RPE to be recorded. Resistance exercise intensity was increased to 130 bpm and 160 bpm, respectively.
520 $a Heart rates fell within five beats of the intended range, with no significant differences at any range for the three modes. There was no significant effect for mode in oxygen uptake or energy expenditure, but there was a significant effect for gender, with men having significantly greater values than women for both variables. There was no significant effect due to gender for RPE, but there was a significant main effect due to mode of exercise, with the cycle ergometer yielding a significantly greater RPE at a heart rate of 160 bpm than either of the other two modes. The elliptical machine and treadmill are recommended over the cycle ergometer for fitness improvements and weight loss due to their ability to expend energy at a lower RPE in most people.
