“With respect to electromyographic (EMG) intensity, the right erector spinae seems to be highly activated, especially during the acceleration phase, whereas the oblique abdominal muscles showed moderate to low levels of activation. The pectoralis major, subscapularis and latissimus dorsi muscles of both sides showed their peak activity during the acceleration phase. High muscle activity was found in the forearm muscles, especially in the wrist flexor muscles demonstrating activity levels above the maximal voluntary contraction. In the lower limb higher muscle activity of the trail side was found.”

Erector spinae muscles
The erector spinae or spinal erectors is a set of muscles that straighten and rotate the back. The erector spinae is not just one muscle, but a group of muscles and tendons which run more or less the length of the spine on the left and the right.
Exercises for the erector spinae
- Deadlift
- Hyperextension
- Good-morning
