Outcome Measures

Primary Outcomes (3)

  • Physical activity

    Changes in physical activity intensity (minutes and percentage during 72 hours) and levels (minutes and percentage during 72 hours) between trials

    72 hours (24 hours before exercise day, exercise day and 24 hours after exercise day)

  • Energy intake

    Changes in total and macronutrient energy intake between trials

    72 hours (24 hours before exercise day, 24 hours during exercise day and 24 hours after exercise day)

  • Sedentary behaviour

    Changes in sedentary behaviour (minutes and percentage during 72 hours) between trials

    72 hours (24 hours before exercise day, exercise day and 24 hours after exercise day)

Secondary Outcomes (3)

  • Heart Rate

    During 45 minutes exercise

  • Rating of Perceived Exertion (RPE)

    During 45 minutes exercise

  • Visual analogue scale (VAS)

    Baseline upon wake up, 15 minutes before exercise and 15 minutes after exercise
