As shown in Table 2, a significant reduction of energy intake occurred in group E compared to the other groups (p < 0.05). In contrast, group C showed significantly higher energy intakes than the other groups (p < 0.05). The energy intake levels were similar in groups R, O, and G. As shown in Fig. 2, energy intake of group E remained at low levels throughout the 9 weeks exercise. At the end of 6th week, there were no significant differences of energy intake among groups, except group C which showed significant greater energy intakes than the other groups (p < 0.05). The levels of energy intake in groups O and G restored at 7th week after taking carbohydrate supplements for 1 week, while a slow recovery of energy intake was also found in group R
