Abstract

Introduction: To achieve benefits in a fitness program, such as improved quality of life and cardiorespiratory fitness, it is required to apply a load of proper training regarding the intensity, duration, frequency and mode. The conversion of metabolic equivalent (MET) for motor work will allow the use of simpler and more conscious of the variable intensity to the exercise prescription, allowing the most appropriate and targeted prescription, according to the ACSM. Objective: To determine indirectly metabolic equivalents during exercise performed on a treadmill at different speeds. Materials and Methods: 45 sedentary between 22 to 67 years performed a maximal incremental treadmill test with continuous measurement of oxygen uptake (VO2) using a gas analyzer. Metabolic demands, in METs, were related to the intensity of exercise. Results: The Pearson correlation coefficient between METs and walking or running speed was 0.98 (p <0.01). Using the regression equation (METs = 0.9103 * Vel -0.4674; Vel as speed walking/running), it was observed that the rate of walking/running overestimates by approximately 1 MET the corresponding metabolic equivalent. Conclusion: There is a direct relation between the motor work, expressed in speed, and the metabolic equivalent. In sedentary individuals, the speed of treadmill running overestimates at approximately 1 MET the absolute exercise intensity, expressed in metabolic equivalents.
