This paper discusses two experiments conducted to determine some of the various effects of dynamic muscular loading upon the Total Integrated Muscular Activity (TIMA). Parameters of interest are power, time, rate, and task. In one experiment the dynamic loading of muscles was applied through a cranking operation and in another experiment it was applied through a continuous push-up task. Power, time and rate had a significant effect upon TIMA. The conditions under which TIMA is minimized were determined for the two experiments.
