support heart rate acceleration by the reduction of the APD. However, number of
calcium and electrophysiological remodeling remain controversial. Therefore it is
highly recommended to scrutinize each article (Table 5.1 and other feature ones)
with a particular attention on how the data are expressed and what were the training
protocols.
In conclusion, despite the clarifications needed to decipher healthy cardiomyo-
cyte remodeling evoked by chronic exercise, training beneficial effects are well
admitted. Cardiac cell plasticity ensure the cardiac adaptation to exercise training
and offers an interesting mean of action to counteract physiological disturbances
induced by cardiac pathologies.
