EFFECT OF EXERCISE MODALITY ON EFFORT SENSE AT PREFERRED INTENSITY421

Abstract

This study was aimed to investigate the effects of exercise modality on heart rate and ratings of perceived exertion (RPE) during preferred effort. Eleven males and 5 females performed three kinds of exercise for 30 min at a voluntary pace or load which each of the subjects preferred. The modes of the exercise were an actual cycling and a running at flat road and a cycle ergometer exercise at a laboratory. The subjects were instructed to be able to change the pace and/or load at any times. Heart rate (HR) was measured during exercise as one of input variable to effort sense. Blood lactate concentrations (LA) were also measured before and after exercises. Data were compared between three kinds of exercise modes. The LA did not increase significantly for all trials. The average HR and RPE during running were significantly higher than both cycling bouts as follows:Table These results indicate that the preferred intensity is different between running and cycling. It suggests that the preference for levels of activity may not be decided only by effort sense.
