Measurement of oxidative capacity in the muscle of a 60 yr old female volunteer. a) [PCr] map at rest b) Dynamic imaging of PCr resynthesis post exercise at 12 s temporal resolution. PCr levels in the TA are depleted immediately after exercise (t = 12 s), and fully recover after sufficient time (t = 360 s). c) Evolution of [PCr] in the TA muscle post-exercise, together with the fit of Eq. 3 to the data in order to estimate kPCr. Oxidative capacity of the TA muscle (Qmax ) was measured at 0.69 mM ATP s−1.
