Figure 4. Maximal aerobic exercise (3.5 ± 0.2 min) increases autonomous, but not maximal, in vitro CaMKII activity in human skeletal muscle.

Shown are the activities measured from tissue lysates (left column) and immunoprecipitates (IP, right column). Data are means ± s.e.m.n = 9 (lysate), n = 6 (IP). * Significantly different from Basal, P < 0.05.
