The impact of 10-minute activity breaks outside the classroom on male students' on-task behaviour and sustained attention: a randomised crossover design.

Abstract

The aim was to evaluate the impact of a brief activity bout outside the classroom on boys' attention and on-task behaviour in the classroom setting. Fifty-eight boys (mean age 11.2 ± 0.6 years) were recruited from a boys' elementary school in Adelaide, South Australia. Two year 5 and, similarly, two year 6 classes were assigned using a crossover design to either four weeks of a 10 minute Active Lesson Break followed by four weeks of a 10 minute Passive Lesson Break (reading) or visa versa. Attention was quantified using a computerised psychomotor vigilance task, and on-task behaviour by direct observation. Neither the Active Lesson nor the Passive Lesson condition significantly affected sustained attention or on-task behaviour, and there were no significant differences between conditions. There was no impact on participants' sustained attention or on-task behaviour after a short activity break between lessons. Brief activity breaks outside the classroom do not compromise participants' on-task behaviour or attention levels upon returning to the classroom, although improvement in these variables is not seen either. However, the results suggest that active breaks are effective for accruing moderate-to-vigorous physical activity without compromising classroom behaviours.
