Energy Demand Assessment Between Exercising and Non-Exercising Young Female Collegiate During a Single Exercise Bout

Abstract

Balancing energy requirement with energy availability during determination for any exercise is of importance to performance. This study was set up to evaluate the influence of regular exercise on energy demand for a given exercise bout among exercising and non-exercising young female College students from University of Lagos using the different energy determining equations available. Sixty volunteer young female students were grouped into two: exercising (Ex-Sub) and non-exercising (NonEx-Sub) subjects. Their heights, weights, ages were recorded, while their blood glucose and blood pressure levels, as well as heart rates were measured before and after the exercise. Two minutes warm-up on the cycle ergometer at 40 km/hr was allowed while gradually increasing the speed to 70km/hr lasting for five minutes. Using the Heart Rate and the estimated VO2max (VO2) the energy demand was determined. The basal systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate were significantly lower in Ex-Sub compared with NonEx-Sub. Although, both ExSub and NonEx-Sub recorded a significantly lower SBP after exercise, Ex-Sub result before and after the exercise were significantly lower compared with that of NonEx-Sub. Both ExSub and NonEx-Sub recorded a significant reduction in heart rate after the exercise. The basal and after exercise heart rate in Ex-Sub was significantly lower, while both the estimated VO2max and energy demands were significantly higher in ExSub compared to NonEx-Sub. Regular exercise confers an advantage by modifying cardiovascular parameters with an added advantage on efficient and reduced energy utilization in the exercising subjects.
