Abstract

The high-intensity intermittent exercise (HIIE) has been considered an efficient strategy to control or decrease fat mass and it is considered superior than moderate-intensity training is some situations. Research has been conducted to explain the advantage of HIIE in reducing fat mass in a greater rate, and two hypotheses have been raised to explain this finding: the superior effect in appetite suppression and greater oxygen consumption post-exercise with consequent higher energy expenditure. However, the outcomes from both hypotheses depend on a proper assessment of energy expenditure, mainly of the HIIE because it has a higher anaerobic component in relation to the moderate intensity exercise and it is known that an anaerobic contribution is more difficult to determine and oftentimes it is neglected. Thus, the aim of the present study is to compare energy expenditure during HIIE, analyzing the contributions of the anaerobic (analyzed by two methods) and oxidative energy system. For this, physically active men will perform six experimental sessions: the first session will consist of an incremental test to identify maximum aerobic power; the second through the fifth session will consist of submaximal test at 40, 50, 60, 70, 75, 80, 85, 90% of maximum aerobic power (two intensities each day); this protocol is one method of energy expenditure estimation; and finally in the sixth session the participants will perform the HIIE protocol (one minute at 100% of maximal load obtained in incremental test followed by one minute of passive rest). The estimation of anaerobic contribution will be conducted by two methods: a) the excess post-exercise oxygen consumption plus delta lactate method and b) oxygen deficit method. Estimation of oxidative contribution will be carried out through the measurement of oxygen consumption during activity. The total energy expenditure in HIIE estimated by different methods will be compared using paired t test, and relative energy expenditure from each energy system in different methods will be compared using a two-way (method and energy system).
