Data from: Effects of an acute bout of aerobic exercise on immediate and subsequent three-day food intake and energy expenditure in active and inactive pre-menopausal women taking oral contraceptives

There was a condition effect for absolute energy intake (exercise vs. control: 3363 ± 668 kJ vs. 3035 ± 752 kJ; p = 0.033, d = 0.49) and relative energy intake (exercise vs. control: 2019 ± 746 kJ vs. 2710 ± 712 kJ; p < 0.001, d = −1.00) at the ad libitum lunch. There were no significant differences in energy intake over the four days in active participants and there was a suppression of energy intake on the first day after the exercise experimental day compared with the same day of the control condition in inactive participants (mean difference = −1974 kJ; 95% CI −1048 to −2900 kJ, p = 0.002, d = −0.89).

There was a group effect (p = 0.001, d = 1.63) for freeliving energy expenditure, indicating that active participants expended more energy than inactive participants during this period. However, there were no compensatory changes in daily physical activity energy expenditure. These results support the use of low-intensity aerobic exercise as a method to induce a short-term negative energy balance in inactive women taking oral contraceptives.
