Moving to Learn and Cope: Physical Activity and Physical Education as a School-Based Lever for Concentration, Academic Stress and Aggression in Adolescents — A Narrative Review with Implications for Indian Schools : Physical activity, concent

Abstract

Background: Indian secondary pupils face heavy academic pressure. High levels of academic stress and
aggression are common among them, and many report difficulty in concentrating. At the same time, most
adolescents do not meet recommended levels of physical activity. Physical education is the one school
subject that can raise activity for every pupil. Yet in examination years it is often treated as expendable.
Objective: To review evidence on whether physical activity, physical fitness and school-based physical
activity programmes are related to three psychological characteristics of adolescents: concentration,
academic stress and related emotional difficulties, and aggression. A second aim was to consider the
implications for physical education in Indian secondary schools.
Methods: Narrative review. Studies identified during the first author’s doctoral research were supplemented
by targeted searches for recent systematic reviews and meta-analyses. The evidence was organised by
outcome and by the mechanisms proposed to link activity with each outcome.
Results:
• Concentration: The evidence is most consistent here. Fitness explained about a quarter of the
variance in adolescents’ attention scores. Eight weeks of endurance, strength or coordination
training improved attention. Short classroom active breaks raised concentration performance in a
cluster-randomised trial. Meta-analyses report moderate gains in attention (SMD = 0.56) and
smaller gains in executive function.
• Emotional outcomes: Physical activity interventions reduced depressive symptoms in children
and adolescents (Hedges’ g = −0.29), and evidence for anxiety is small but favourable. No trial
was found that targeted academic stress itself.
• Aggression: Sports interventions reduced aggression overall (SMD = −0.37), but the effect was
not robust. It appeared for non-contact sports and not for high-contact sports. Longitudinal data
suggest that self-control may carry part of the link, although the indirect effect was small.
• Indian evidence: Almost all of this evidence comes from outside India. No Indian trial was found
that tested physical activity against these outcomes in secondary pupils.
Conclusions: Physical activity is a plausible, low-cost lever for supporting concentration and emotional
well-being in adolescents, and possibly for reducing aggression. The case is strongest for concentration.
Indian schools should protect daily physical education, including in the board-examination years. Classroom
active breaks and coordinative and non-contact activities deserve priority. Cluster-randomised trials in
Indian state-board and national-board schools are needed.
