Brief Summary

ACS examined the potential influence of intermittent physical activity breaks of various intensities (control, light, moderate, vigorous) on measures of immediate mental performance, mood, hunger and several metabolic outcomes in children aged 7-11 years. We build upon previous work to hypothesize that higher-intensity intermittent physical activity breaks throughout an 8-hour day will improve immediate mental performance, mood, and post-exercise physical activity levels, while reducing hunger and post-exercise food intake.

Outcome Measures

Primary Outcomes (1)

  • Physical activity energy expenditure

    Physical activity energy expenditure throughout the condition day and over the next three days. Participants wore an accelerometer for four days. Energy expenditure was calculated from accelerometer data.

    4 days

Secondary Outcomes (8)

  • 40-item immediate mental performance math test

    1 day

  • Dietary intake

    4 days

  • Physical activity minutes

    4 days

  • 4-item hunger and satiety visual analog scale

    1 day

  • Single-item ratings of perceived exertion

    1 day

  • +3 more secondary outcomes

Interventions

The light-intensity condition consisted of 8 hours of sitting interrupted with 2--minute, light--intensity activity breaks performed at 25% of heart rate reserve (HRR) every 18 minutes. Standardized meals were provided.

Light-Intensity Condition

The moderate-intensity condition consisted of 8 hours of sitting interrupted with 2--minute, moderate-intensity activity breaks performed at 50% of heart rate reserve (HRR) every 18 minutes. Standardized meals were provided.

Moderate-Intensity Condition

The high-intensity condition consisted of 8 hours of sitting interrupted with 2--minute, vigorous-intensity activity breaks performed at 75% of heart rate reserve (HRR) every 18 minutes. Standardized meals were provided.

High-Intensity Condition

The sedentary condition consisted of 8 hours of sitting interrupted with 2-minutes of screen time every 18 minutes. Standardized meals were provided.
