摘要：Running is one of the most popular physical activities performed for health maintenance, training prescription, leisure and physical tests. The biomechanics evaluation is an important tool for running performance improvement. Treadmill running is often used for biomechanics evaluation because allow controlled conditions for biomechanics data acquisition, making possible the analysis of the factors involved in the muscular fatigue development. Prolonged run or run performed in a high intensity induces changes in the electromyographic and kinematic parameters, resulting from a fatigue process. Moreover, the literature shows that previous activities - such as cycling - modify the subsequent running pattern. Key words: running, fatigue, biomechanics, health.
