ELECTROMYOGRAPHICAL ANALYSIS OF DOUBLE POLE ERGOMETRY: STANDING VS. SITTING.

Abstract

This study assessed the difference in stand-up athlete’s muscle activity of the rectus femoris in standing and sitting using a double pole ergometer. Five subjects participated in two technique specific peak VO2 tests, and a percentage of the maximum scores were used to determine stages for analysis of the electromyography data that was collected. An ANOVA revealed a significant difference in electromyographical activity between ski position and stage using a pre-determined alpha level of p<0.05. Separate paired T-tests were used to determine that there was no statistical difference in muscle activity between the two stages in sitting (t=1.464, p=0.217). However, there was a statistical difference between stages in the standing position (t= -5.023, p=0.007).
