The effect of milk consumption with different temperatures after resistance exercise on appetite and energy intake in active girls: A pilot study

Abstract

Abstract Study aim: The aim of this study was to investigate the effect of milk consumption with different temperatures after resistance training on appetite and energy intake (EI) in active girls. Material and methods: Ten healthy female athletes (age: 21.9 ± 3.07 years) completed 2 trials with 1 week apart in conter-balance and crossover fashion. In overnight fasting state, subjects did resistance exercise (70% of 1RM for 5 movements) and then consumed 250 ml of milk at 60°C or 2°C. One hour after exercise, a meal was served to all subjects for lunch. Subjects filled in the appetite questionnaire 4 times and calorie intake was measured on the day of exercise and 24 hours after. Results: Paired t-test showed that the lunch EI after consuming cold milk was significantly lower than hot milk (p = 0.003). Also, the 24h EI in exercise day was significantly lower in cool vs. hot milk consumpion (p < 0.001) and this reduction was not offset the next day. There was no significant difference in next 24h EI, macronutrient composition and appetite between the two situations. Conclusions:The results of the present study showed that consuming low temperature milk after resistance exercise can be a useful strategy to reduce EI that can be used for weight loss programs.
