Figure 1.

Changes in peripheral insulin sensitivity and glucose oxidation upon the timing of exercise training either in the morning (AM) or in the afternoon (PM). (a) Changes in peripheral insulin‐stimulated glucose disposal (from basal to insulin‐stimulated) were significantly greater in the PM group compared to the AM group. Data are expressed as means ± SD. *p < .05. n = 11 for the AM group and n = 15 for the PM group. (b) Changes in insulin‐stimulated glucose oxidation (from basal to insulin‐stimulated) were significantly greater in the PM group compared to the AM group. Data are expressed as means ± SD. *p < .05. n = 7 for the AM group and n = 16 for the PM group. (c) Changes in insulin‐mediated suppression of plasma‐free fatty acids (%) improved significantly more in the PM group compared to the AM group. Data are expressed as means ± SD. *p < .05. n = 12 for the AM group and n = 19 for the PM group
