Dear Biomch-l'ers:

I was wondering if anyone out there had a relatively simple answer (with
possible references) to this question:

During rapid arm movements with a voluntary stop, what PERCENTAGE of the
movement time is spent with the angonist muscles activated (acceleration
burst)? Antagonist muscles activated (braking burst)? And reactivation of
the agonist muscles (clamping burst)? Example: 40% A Burst; 40% B Burst;
20% C Burst.
