Whole body fat and carbohydrate oxidation expressed as percent of EE for (A) paraplegic and (B) non-disabled subjects. Values are means ± SD; n = 10 paraplegic and 7 non-disabled subjects. CHO, carbohydrate; VO2peak, peak oxygen consumption. Significant main effect of stage for fat oxidation for paraplegic: stage 1 > stages 2–4 (P < 0.048), stage 2 < stage 1 (P < 0.048), and stages 3 and 4 < all previous stages (P < 0.008). Significant main effect of stage for CHO oxidation of paraplegic: stage 1 < stages 2–4 (P < 0.048), stage 2 > stage 1 (P < 0.048), and stages 3 and 4 > all previous stages (P < 0.008) for carbohydrate. Significant effect of stage for fat oxidation of non-disabled: rest > stages 1–4 (P < 0.038), stages 3 and 4 < all previous stages (P < 0.015). Significant effect of stage for CHO oxidation of non-disabled: rest < stages 1–4 (P < 0.038), stages 3 and 4 > all previous stages (P < 0.015).
