Physiological changes during prone and treadmill exercise

The mean value for the heart rate at stage III of the prone exercise is between the rates at stages 2 and 3 of the Bruce protocol. The mean systolic blood pressures at each stage closely matches that during treadmill exercise. The diastolic Figure 9.3. Ergometer for the performance of prone exercise.

Oxidative Phosphorylation

Schematic representation of creatine-stimulated respiration at the inner mitochondrial membrane of a saponin-skinned cardiac fibre. Excess creatine (Cr) shifts the local Mi-CK reaction in favour of an increase in local ADP. ADP is then transported via the adenine nucleotide translocase into the mitochondrial matrix to stimulate respiration. IMM, inner mitochondrial membrane OMM, outer mitochondrial membrane SL, sarcolemma mit-CK, mitochondrial creatine kinase bound to the IMM....
