muscle

Axial and appendicular muscle strength in boys and girls is about the same until age 10 when a disparity begins to develop (5).

These measurements may also be important in the measurements of appendicular muscle atrophy in clinical situations of forced bed rest or splinting of limbs.

Specifically, we investigate the recruitment of axial and appendicular muscle responses and changes in autonomic responses as additional indicators of the presence of a startle response during a rear-end collision.

2] delivery-utilization matching in contracting appendicular muscles include: a) the muscle "pump" effect; b) local vasodilatation; c) parasympathetic and sympathetic tones, and d) differential patterns of muscle fiber recruitment, as reviewed by other authors (4,10,19).

In their study the authors investigated the recruitment of axial and appendicular muscles along with autonomic responses and showed that responses to whiplash-like events involves both a descending recruitment pattern of axial and appendicular muscles and increased sympathetic responses.
