Prior training modestly blunts high-fat diet-induced glucose intolerance. Intraperitoneal glucose tolerance test (A; SED LFD, ●; TR LFD, ■; SED HFD, ▲, TR HFD, ▼) and total area under the curve (B: gray bars denote SED, while white bars denote TR) after 3 days of high-fat feeding. Stippled bars indicate LFD to easily distinguish the two feeding treatments. Data are presented as means ± SE (A and B: n = 9). *Significant effect of the high fat diet, P < 0.05. †Significant effect of exercise training, P < 0.05.
