Yoga is an alternative form of exercise that improves health and fitness through the integration of the mind, body, and spirit. The purpose of this study was to compare the impact of three warrior poses on quadricep muscle activity. The null hypothesis stated that no significant differences would be found in quadriceps muscle activation between Warrior poses I, II, and IV. Six college-aged females (average age of 20.67 ± 0.62) with at least two years of experience participated in the study. Surface electromyography (sEMG) was recorded during maximum voluntary isometric contractions (MVICs) of the right and left vastus medialis (VM), and vastus lateralis (VL) to analyze muscle activity. Participants performed the selected poses and held each pose for ten seconds and performed each pose three times. A 60-second break was given between each pose. Results are currently being analyzed for statistical significance. ANOVA repeated tests are currently being conducted to compare quadriceps muscle activation between the selected Warrior poses: I, II, and IV.

Biographical Information about Author(s)

As an exercise science major, the author is pursuing a future career in physical therapy (PT). Previous research has shown that yoga has been incorporated in PT rehabilitation. This study was done to examine quadricep muscle activation while performing yoga. This investigation could add to current knowledge and may offer a potential prevention or rehabilitation method for those who are prone to injury or have been injured.
