Figure 5. Juvenile exercise training does not alter the mRNA expression of genes that regulate cardiac growth or the apoptosis markers Bcl‐2 and Bax .

Data presented for the following genes: Igf‐1 (A), Myh6 (B), Gata4 (C), Nkx2.5 (D), Foxo1 (E) and Cebpb (F), Bcl‐2 (G) and Bax (H). Data presented as means ± SD. n = 11 per group. Short‐term (4 weeks) endurance training during juvenile (Juv Ex, 5–9 weeks old) and adult (Adult Ex, 20–24 weeks old) life. 9‐week‐old rats were compared using an unpaired t test. 24‐week‐old rats were compared using one‐way ANOVA with Newman‐Keuls post hoc analysis.
