Glucometry and gravimetry of rats at the end of 8 wk of diabetes and exercise training

	NN	ND	EN	ED
Body mass, g	379 ± 13b,d	302 ± 32a	341 ± 19	311 ± 39a
Heart mass, g	1.05 ± 0.05	1.03 ± 0.09	1.12 ± 0.09	1.07 ± 0.11
Heart/body mass, mg/g	2.78 ± 0.09b,c,d	3.43 ± 0.14a	3.27 ± 0.15a	3.44 ± 0.22a
Plasma glucose, mg/dl	122 ± 12b,d	546 ± 63a,c	111 ± 21b,d	482 ± 171a,c
HbA1c, %	4.8 ± 0.4b,d	10.8 ± 1.6a,c,d	5.2 ± 0.2b,d	7.8 ± 0.4a,b,c

Values are means ± SE; n = 8 rats/group. NN, nonexercised nondiabetic; ND, nonexercised diabetic; EN, exercised nondiabetic; ED, exercised diabetic. Significant difference from

^aNN,

^bND,

^cEN, and

^dED: P ≤ 0.05. Factorial (2 × 2) ANOVA interaction effect (health status × physical activity) was significant for body mass (P = 0.021), heart/body mass (P = 0.001), and HbA1c measurements (P = 0.001), while it was not significant for heart mass and plasma glucose measures.
