The current study examined muscle activity via electromyography of the flexor carpi radialis (FCR), ulnaris (FCU), and extensor carpi radialis (ECR), ulnaris (ECU) during two variations of three separate yoga poses. Nine participants (n=9) performed three different yoga poses: plank, side-plank, and upward dog; in two separate variations, (V1) with the wrists in a passive hyperextended position, and (V2) with the wrists in a neutral position where the participants made a fist and performed the pose in that position. There were no differences between poses or variations for ECR. A difference was found between variations, but not poses for ECU. FCR and FCU were different between poses, but not variations. The only interaction was for the FCR. Due to the increased muscle activity in V2, performing yoga in V1 position may allow a yoga session to be completed with less fatigue and risk for injury.
