Abstract Objective To determine the effects of Yoga posture on the Trunk Muscle Activities by examining the muscle activation patterns in erector spine and rectus abdominis muscles. Design Setting Repeated-measures of descriptive study done at Biomechanics laboratory, Biomedical Engineering Department, NIT Raipur. Participants In this work, participants with no previous experience of Yoga and low back pain (mean age ± SD, 18.0 ± 4.3 y; 10 Males) were recruited. Methods we recorded muscle activity from erector spine and rectus abdominis muscle for two different yoga poses. By maximum voluntary contraction procedure, mean muscle activity value for two different yoga poses were determined. Results There were significant effects of yoga pose on trunk muscle activities. We found significant (p<0.0001) change in trunk muscle activation during cobra pose as compared to boat pose. Conclusions From the result we found variations in trunk muscle activities during cobra pose and boat pose. There was significant difference in muscle strength during cobra pose as compared to boat pose; therefore the Cobra pose is effective for strengthening Erector spinae muscle and this pose can be incorporated in yoga training module for addressing low back pain (LBP).
