Abstract

The purpose of this study was to determine and to compare EMG characteristics of the vastus medial quadriceps in Chilean rowers in hypoxia. The sample was 11 Chilean elite rowers. The evaluation procedure consisted of every subject performing a maximal test of incremental ergospirometry intensity until fatigue. The EMG analysis was implemented when the sportsmen reached the VO2max intensity with wireless EMG. In the analysis, RMS EMG signals were utilized. The results showed a significant difference between EMG activity in normoxia pre-altitude and normoxia post-altitude after 21 days in hypoxia.
