EAP exercise preferentially elicits cardiac hypertrophy. Absolute heart weight (A), heart weight standardized to body weight (B), heart weight standardized to tibia length (C) was determined in hearts isolated from mice after 6 weeks of TRE (n = 8–9 mice/group). Gene expression for insulin-like growth factor 1 (IGF-1) was elevated in both exercise groups (n = 4–5 mice/group; D). Cardiomyocyte cross-sectional area was increased in EAP and LAP hearts compared to SED (n = 5 mice/group; E). Scale bar is 20 µm. *Different from SED, p < 0.05.
