The contribution of healthy nutrition to developing pupils’ competence during physical education and sport lessons: A field study in secondary schools of the Ouled Derradj District, M’Sila Province

Abstract

This study aimed to examine the role of healthy nutrition in developing pupils' competence during physical education and sport (PES) lessons, with a particular focus on the secondary education stage, from the perspective of PES teachers in secondary schools across the Ouled Derradj District of M’Sila Province. A descriptive research design was adopted because of its suitability for the study's nature. The sample comprised 10 PES teachers selected through random sampling. Data were collected via a purpose-designed questionnaire. The main findings indicated (a) a statistically significant positive association between adherence to healthy nutrition and improved pupils' competence during PES lessons, in terms of physical performance as well as endurance and activity levels; (b) pupils who follow a balanced dietary pattern (before, during, and after the lesson) demonstrate better concentration, faster responsiveness, and reduced fatigue than their peers do; and (c) poor dietary habits (such as excessive consumption of sugars, carbonated beverages, and fast food) negatively affect motor performance and increase manifestations of lethargy and exhaustion during the lesson.
