Comparison of Energy Expenditure and Cardiac Effort Induced by Treadmill Walking and Stationary Cycling at Moderate Perceived Exertion by Young Males
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 7
Abstract
Introduction: Moderate intensity aerobic exercise is recommended for the health promotion. In an indoor environment, the treadmill and cycle ergometer are the commonest modes of aerobic exercise. At home or gyms, an individual exercise based on the perceived exertion rather than the objective parameters that are used to classify the exercise intensity in laboratories. The aim of the present study was to compare the treadmill with cycle ergometer for energy expenditure and rate pressure product reactivity in a thirtyminute exercise bout by moderately active, apparently healthy, young males at a rating of perceived exertion (RPE) of 13. Material and Methods: Sixteen males, aged 21±1 years with BMI of 20.8±1.6 kg/m2 were involved in the present experimental study. Participants performed two separate exercise trials on the treadmill and stationary upright cycle ergometer. An indirect calorimetric equation based on the respiratory gas exchange analysis was used to calculate the energy expenditure. Blood pressure and heart rate response were obtained by an automated blood pressure monitor. Rate pressure product serves as a linear correlate of cardiac effort and was calculated as the product of systolic blood pressure and heart rate. Student t-test was applied for the comparative analysis. P<0.05 was considered significant. Results: Exercise on the treadmill caused a significantly higher energy expenditure, while the cardiac effort was similar for both the modalities of exercise at moderate perceived exertion. Conclusion: The results of the present study suggest that the treadmill walking might be preferred over cycling for the health promotion in young males.
