Why is high intensity anaerobic exercise limited in duration?

he lumbricals flex the fingers at the metacarpophalangeal (knuckle) joints, and extend the fingers at the interphalangeal joints. On a model, examine the path of these muscles and speculate why they act as flexors at one joint and extensors at another.
