Document Summary

Excessive concentric contraction: tight muscles causing body to crunch in the back. Upper trapezius bulky, restrict total range of eccentric contraction (muscle length shortens) Hamstring group tight te(cid:374)do(cid:374)s (cid:374)ear the (cid:374)ears (cid:894)(cid:272)a(cid:374)"t full(cid:455) e(cid:454)te(cid:374)d the k(cid:374)ee(cid:895) Lower legs and achilles shortening of gastrocnemius. Medial, lower trapezius slouching stretches the back. Posterior deltoids, teres major, infraspinatus protracted shoulders causing tight inner shoulder, stretched back shoulder rotator cuffs.

Excessive eccentric contraction: extensor muscles of wrist (typing position), anterior aspect of upper leg. The gh joint and pectoral girdle: movement from shoulder (gh) joints vs. shoulder blades (scapular); movements from pectoral muscles vs. the shoulder gh joints. Mid/upper back: shoulder blades are retracting and depressing during movement.
