Strain comparison of body weight and work before and after exercise training

		Body Weight, g		Work, kg·m
Strain	n	Pretraining	Posttraining	Pretraining	Posttraining	Change
B6	12	21.7±0.6	22.3±0.5†	1.31±0.15†	1.65±0.20†	0.34±0.12*

Values are means ± SE for n mice. C57BL/6J (B6): n = 8 males, 4 females; FVB/NJ (FVB): n = 5 males, 6 females; F₂: n = 96 males, 92 females.

^*P < 0.05 vs. all other strains;
