INTEGRATED IMPACT OF PHYSICAL ACTIVITY, NUTRITION AND MENTAL HEALTH ON ATHLETE PERFORMANCE:

Abstract

Background: Athlete performance is influenced by multiple interrelated factors, including physical activity, nutrition, and mental health. Understanding their combined effects is essential for developing effective performance enhancement strategies. Objective: The present study aimed to examine the integrated impact of physical activity, nutrition, and mental health on athlete performance using a multidimensional analytical approach. Methods: A quantitative, cross-sectional design was employed. A total of 500 athletes aged 18–35 years were selected using stratified random sampling from universities, sports clubs, and training centres. Data were collected using the International Physical Activity Questionnaire (IPAQ), a structured sports nutrition scale, the Depression Anxiety Stress Scales (DASS-21), and a composite athlete performance measure. Data were analysed using correlation, regression analysis, and Structural Equation Modelling (SEM) through SPSS and AMOS. Results: The findings revealed that physical activity, nutrition, and mental health were all significantly associated with athlete performance (p < 0.01). Multiple regression analysis showed that all three variables were significant predictors of performance, with physical activity demonstrating the strongest effect. SEM results confirmed a good model fit and indicated that mental health partially mediated the relationship between physical activity, nutrition, and athlete performance.

Conclusion: Athlete performance is a multidimensional outcome shaped by the integrated effects of physical activity, nutrition, and mental health. The study highlights the importance of adopting a holistic approach in sports science that combines physical training, nutritional planning, and psychological support.
