Calcium uptake and release of SSM. SSM calcium handling regarding Ca2+ uptake (a), liberation (b) and net retention (c). A and B show fitted nonlinear regression curves, arrow (b) indicates significant slope differences of IR30/30 and IR40/30 vs. IR0/30, respectively. Bars in C represent means ± standard error of the mean; *p ≤ 0.05, **p ≤ 0.01. SSM: subsarcolemmal mitochondria; RFU: relative fluorescence units
