Key result
Low-intensity endurance training for 8 weeks increased left ventricular myocyte length (162.2 vs 152.5 μm, P<0.05) and cell shortening (8.6% vs 7.5%, P<0.05) in rats, but not right ventricular myocytes.
p-value: p=<0.05
Low-intensity endurance training induces structural and functional improvements in left ventricular, but not right ventricular, myocytes in rats.

Hypothesis-generating for ventricular-specific myocyte adaptations in rodents; human studies needed before clinical relevance.
Carneiro‐Júnior et al. (2013) studied Healthy (n=14). Low-intensity endurance training (LIET) vs. Control was evaluated on Structural and mechanical properties of right and left ventricular myocytes (e.g., cell length, volume, shortening) (p=<0.05). Low-intensity endurance training for 8 weeks increased left ventricular myocyte length (162.2 vs 152.5 μm, P<0.05) and cell shortening (8.6% vs 7.5%, P<0.05) in rats, but not right ventricular myocytes.
