Cardiac cell hypertrophy (A) representative images magnified 200x; arrows represent hypertrophied cells. (B) Table representing quantification of hypertrophy scores at 9 days after doxorubicin treatment. Hypertrophy score 0, absence of cell hypertrophy; 1 ≤ 25%; 2, 25–50%; and 3 > 50% of cell hypertrophy. G1, HIIE day 1 post-DOX; G2, HIIE day 2 post-DOX; G3, HIIE day 3 post-DOX; and SED, no exercise. No significant difference between groups
