MicroRNAs (miRNAs) dynamically regulated in the heart by exercise training. (A) 120 miRNAs are clustered according to their reported expression altered by different exercise training in the heart. (B) miRNAs marked in green or blue have been reported to be up-regulated or down-regulated after exercise, respectively. The responses of miRNAs marked in black have been reported to vary depending on the health of the animals and/or the timing and exercise model studied. ECC, Excitation–contraction coupling.
