During the preload trial, participants shall consume a whey protein beverage 15 minutes after completion of the exercise bout. This will consist of 23g whey protein isolate powder (20g protein) combined with 200ml water and 10 drops of energy-free flavouring to create a milkshake-type beverage. In both other trials an isovolumetric bolus of similarly flavoured water shall be consumed. After a further 15 minutes participants shall consume the same mixed-macronutrient breakfast meal under all conditions, and will subsequently rest for a 240 minute period. An ad libitum pasta meal shall be consumed at the end of this period in all trials in order to assess subsequent energy intake. Regular blood samples shall be collected throughout.
