Project – Impact of Physical Exercise on Academic Performance of Secondary School Students. A Study of five Selected Secondary Schools in Ikeja

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Education is widely recognized as a fundamental tool for national development, and students’ academic performance remains a key indicator of educational success. In recent years, increasing attention has been given to factors that influence students’ academic outcomes, particularly lifestyle-related variables such as physical exercise. Physical exercise, which includes structured activities like sports, physical education classes, and recreational fitness activities, plays a crucial role in promoting not only physical health but also cognitive and psychological well-being.

Globally, research has demonstrated a strong connection between physical activity and academic achievement among students. Studies indicate that students who engage in regular physical exercise tend to perform better academically compared to their less active counterparts (Rasberry et al., 2011; Barbosa et al., 2020). For instance, a meta-analysis by Rao (2024) found a significant positive correlation between physical activity and academic performance across different educational levels. Similarly, Loturco et al. (2022) reported that school-based physical activity programs can enhance students’ academic outcomes, particularly in subjects such as mathematics and reading.

The underlying mechanisms through which physical exercise influences academic performance are multidimensional. Physical activity improves brain function by increasing blood flow and oxygen supply to the brain, thereby enhancing memory, attention, and cognitive processing abilities (Hillman, Erickson, & Kramer, 2008). It also contributes to better mental health by reducing stress, anxiety, and depression, which are known to negatively affect learning (Barbosa et al., 2020). Furthermore, participation in sports and exercise fosters discipline, time management, teamwork, and self-esteem—all of which are essential for academic success.

Despite these benefits, there has been a noticeable decline in students’ participation in physical activities, particularly in developing countries like Nigeria. The increasing emphasis on academic achievement, coupled with technological advancements and sedentary lifestyles, has led many schools to reduce the time allocated to physical education (Rasberry et al., 2011). Consequently, students spend more time engaged in classroom activities and less time in physical exercise, which may have unintended negative effects on their academic performance.

In Nigeria, especially in urban areas such as Ikeja, Lagos State, secondary school students are often subjected to intense academic pressure. Parents, teachers, and school administrators prioritize examination success, sometimes at the expense of physical education. While this approach aims to improve academic outcomes, emerging evidence suggests that neglecting physical exercise may actually hinder students’ cognitive development and overall academic achievement (Loturco et al., 2022).

Furthermore, physical inactivity among students has been linked to various health issues such as obesity, poor cardiovascular health, and reduced mental well-being. These health challenges can adversely affect students’ concentration, attendance, and overall school performance (Barbosa et al., 2020). Research also shows that physical activity is not detrimental to academic achievement; rather, it may produce small-to-moderate positive effects on students’ academic outcomes (Rao, 2024).

Given these considerations, it becomes necessary to investigate the relationship between physical exercise and academic performance among secondary school students. This study focuses on five selected secondary schools in Ikeja to determine how physical exercise influences students’ academic outcomes and to provide empirical evidence that can inform educational policies and practices.

1.2 Statement of the Problem

In recent times, there has been growing concern about the declining academic performance of secondary school students in Nigeria. While several factors such as poor teaching methods, inadequate learning facilities, and socio-economic challenges have been identified as contributors, less attention has been given to the role of physical exercise in enhancing academic performance.

Many secondary schools in Ikeja have increasingly reduced the emphasis on physical education due to the pressure to cover academic curricula and prepare students for examinations. As a result, students have limited opportunities to engage in physical activities that could enhance their cognitive functioning and overall well-being (Rasberry et al., 2011). This situation has led to a sedentary lifestyle among students, characterized by prolonged sitting, excessive use of digital devices, and minimal participation in sports or exercise.

Despite evidence suggesting that physical exercise can improve academic performance, many educators and parents still perceive it as a distraction from academic work rather than a complementary activity (Hillman et al., 2008). Consequently, physical education is often undervalued, underfunded, or completely ignored in some schools. This misconception may be contributing to poor academic outcomes, reduced concentration levels, and increased stress among students.

Moreover, there is a lack of empirical studies specifically examining the impact of physical exercise on academic performance among secondary school students in Ikeja. Without adequate local data, it becomes difficult for policymakers and school administrators to make informed decisions regarding the integration of physical education into the school curriculum.

Therefore, the problem of this study is to examine whether physical exercise has a significant impact on the academic performance of secondary school students in Ikeja. This study seeks to fill this gap by providing empirical evidence on the relationship between physical exercise and academic achievement among students in the selected schools.

1.3 Objectives of the Study

The main objective of this study is to examine the impact of physical exercise on the academic performance of secondary school students in Ikeja.

The specific objectives are to:

1. Determine the level of participation in physical exercise among secondary school students in Ikeja.
2. Examine the relationship between physical exercise and students’ academic performance.
3. Identify the effects of physical exercise on students’ concentration and learning ability.
4. Assess the influence of physical exercise on students’ overall well-being and academic outcomes.

1.4 Research Questions

1. What is the level of students’ participation in physical exercise in secondary schools in Ikeja?
2. Is there a relationship between physical exercise and academic performance of students?
3. How does physical exercise affect students’ concentration and learning ability?
4. What is the influence of physical exercise on students’ overall academic performance?

1.5 Research Hypothesis

H₀: Physical exercise has no significant impact on the academic performance of secondary school students in Ikeja.

H₁: Physical exercise has a significant impact on the academic performance of secondary school students in Ikeja.

1.6 Significance of the Study

This study will be beneficial to the following groups:

• Students: It will help students understand the importance of physical exercise in improving their academic performance and overall health.
• Teachers: The study will guide teachers in incorporating physical activities into teaching strategies to enhance learning outcomes.
• School Administrators: It will provide evidence for the inclusion and proper implementation of physical education programs in schools.
• Parents: The study will create awareness among parents about the importance of encouraging their children to engage in regular physical exercise.
• Policy Makers: The findings will assist educational authorities in formulating policies that promote physical education in schools.
• Researchers: It will serve as a reference for future studies in physical and health education.

1.7 Scope of the Study

This study focuses on the impact of physical exercise on the academic performance of secondary school students in five selected secondary schools in Ikeja, Lagos State. The study will consider variables such as students’ participation in physical exercise, frequency of physical activity, and academic performance indicators such as test scores and overall grades.
