It also effectively conditions the long back extensors that run from the lower back to upper back.
2
Stretching of the muscles antagonistic to the extensors - namely, of the flexor muscles - reduces the jerk by inhibiting the extensor spinal nerve cells through the nervous impulses generated by the tense flexor muscles.
3
The exercise did not effect the peak work load, peak oxygen uptake, or muscle function in knee extensors compared with the controls.
4
This throwing movement involves the external shoulder rotators (the posterior shoulder muscles) and the arm extensors (the triceps ).
