Survival curves for four groups: group A: runners; group B: sedentary controls; group C: food-restricted runners; and group D: food-restricted sedentary controls. Survival curve for sedentary control rats in group B is significantly different from that of runners in group A (P < 0.02), food-restricted runners in group C (P < 0.0001), and food-restricted sedentary rats in group D (P < 0.0001). Survival curve for runners in group A is significantly different from that of food-restricted runners in group C (P < 0.01) and food-restricted sedentary rats in group D (P < 0.01).
