Figure 1.

Whole body fat and carbohydrate oxidation expressed as g/minute for (A) paraplegic and (B) non-disabled subjects. Values are mean ± SD; n = 10 paraplegic and 7 non-disabled subjects. VO_2peak, peak oxygen consumption. Significant main effect of stage for fat oxidation of paraplegic: stage 1 > rest, stage 4 (P < 0.008), stage 2 > rest, stages 3 and 4 (P < 0.044), and stage 4 < stages 1–3 (P < 0.008). Significant effect of stage for fat oxidation of non-disabled: rest, stages 1 and 2 > stages 3 and 4 (P < 0.009). Significant main effect of stage for carbohydrate oxidation of paraplegic and non-disabled: each stage > all previous stages (P < 0.008).
