Abstract

The objective this study is to analyze the influence of previous exercise on aerobic performance of short duration performed with different strategies of distribution of the intensity in trained and untrained subjects trained during cycling. Thirty healthy subjects will participate of this study and will be divided into two groups in accordance with their experience level in cycling. In the first visit, the subjects will be submitted to a protocol for the determination of lactate threshold, maximal oxygen uptake (VO2max) and its respective intensity (IVO2max). In the next four visits, the subjects will performed constant workload tests (90%, 95%, 100% and 110% IVO2max) to exhaustion voluntary, for the determination of critical power (CP) and anaerobic work capacity. The CP model will be used for the estimation to the intensity that allows to exhaustion in 3 min (Power 3-tlim). From the sixth to tenth visits, the subjects will performed the following experimental sessions: a) even-pace: 2 minutes of exercise at work constant at Power 3-tlim followed by a maximal exercise (all-out) of 1 min; b) slow start: 2 minutes of exercise with initial intensity 10% below Power 3-tlim, with linear increase until 110% of Power 3-tlim followed for a maximal exercise (all-out) of 1 min; c) fast start: 2 minutes of exercise with initial intensity at 10% above Power 3-tlim, with linear decrease 90% of Power 3-tlim followed by a maximal exercise (all-out) of 1 minute. All these conditions will be performed with and without previous exercise. The mean ± DP of the data will be calculated. In all tests the level of significance will be set at p < 0.05. (AU)
