Effects of training in the fasted state vs. training in the carbohydrate-fed state on blood glucose concentration during a 2-h constant-load exercise bout. Data provided are means ± SE (F: n = 10; CHO: n = 10) and represent values before (pretest) and after (posttest) a 6-wk training period in either the fasted state (F) or with ample carbohydrate intake before and during the training sessions (CHO). Concentrations of blood glucose were measured before and at the end of a 2-h constant-load cycling bout. The workload was 175 ± 6 W and corresponded to 65% of V̇o2max in the pretest vs. 60% of V̇o2max in the posttest. *P < 0.05 vs. pretest. †P < 0.05 vs. CHO. #P = 0.07 vs. pretest.
