PURPOSE: Our study characterizes food and energy intake responses to long-term aerobic (AT) and resistance training (RT) during a controlled 8-month trial. METHODS: In the STRRIDE AT/RT trial, overweight/obese sedentary dyslipidemic men and women were randomized to AT (n = 39), RT (n = 38), or a combined treatment (AT/RT; n = 40) without any advice to change their food intakes. Quantitative food intake assessments (QDI) and food frequency questionnaires (FFQ) were collected at baseline (BEF) and after 8 mo. training (END); body mass (BM) and fat free mass (FFM) were also assessed. RESULTS: In AT and AT/RT, respectively, meaningful decreases in reported energy intake (REI) (-217 and -202 kcal; p < 0.001) and in intakes of fat (-14.9 and -14.9 g; p < 0.001, p = 0.004), protein (-8.3 and -10.7 g; p = 0.002, p < 0.001), and carbohydrate (-28.1 and -14.7 g; p = 0.001, p = 0.030) were found by FFQ. REI relative to FFM decreased (p < 0.001 and p = 0.002) as did intakes of fat (-0.2 and -0.3 g; p = 0.003 and p = 0.014) and protein (-0.1 and -0.2 g; p = 0.005 and p < 0.001) in AT and AT/RT and carbohydrate (-0.5 g; p < 0.003) in AT only. For RT, REI by QDI decreased (-3.0 kcal/kg FFM; p = 0.046), as did fat intake (-0.2 g; p = 0.033). BM decreased in AT (-1.3 kg, p = 0.006) and AT/RT (-1.5 kg, p = 0.001) but was unchanged (0.6 kg, p = 0.176) in RT. CONCLUSIONS: Previously sedentary subjects completing 8 months of AT or AT/RT reduced their intakes of kcal and macronutrients and BM. In RT, fat intakes and REI (when expressed per FFM) decreased, BM was unchanged, and FFM increased.
