Acute effect of physically active rests on cognitive variables and creativity in Secondary Education

Abstract

Abstract. The objective of this study was to know the acute effect of two different types of active breaks (low and high intensity), carried out between two classes, on several cognitive variables such as memory, attention-concentration, mathematical calculation, linguistic reasoning and creativity in high school youth. 136 adolescents of 12.92 ± 0.43 years participated. Three study groups were used: 1) Control group (CG) that remained seated within the class; 2) Experimental group 1 (EG1) that made 1 active break of 4 minutes at low intensity; and 3) Experimental group 2 (EG2) that carried out high intensity exercises. To analyze the effects of the different types of breaks, ANCOVA was used with repeated measures 3 Group (CG, EG1, EG2) x 2 Time (pre, post). Age, sex and studies of the mother were used as covariates. The results showed that active rest improved the participants' later memory (p <0.001). The low intensity active breaks had a similar improvement effect in attention and concentration (21 and 25%, p <0.001). Improvements in the mathematical calculation were observed after both types of active breaks, however, the differences have not become significant. The adolescents showed no improvement in linguistic ability or creativity. It is suggested the inclusion of active breaks, preferably at low intensity, to obtain short-term benefits in the attention, concentration and mathematical calculation in secondary school youth.
