Body Composition and Self-Image: Exploring the Impact on Exercise Motivation and Behavior

Abstract

This study examines how self-perception and body composition (body fat percentage, lean mass, etc.) influence psychological and behavioral outcomes among college students. The research explores how body composition metrics are related to psychological factors such as stress management, enjoyment of physical activity, and leisure activity, and how appearance scores, as a reflection of self-perception, influence these outcomes. Drawing on a sample of 100 undergraduates from Eastern Kentucky University, data were collected through self-reported surveys measuring body satisfaction, exercise frequency, and motivational factors, alongside objective body composition metrics. Statistical analyses revealed that higher appearance scores were associated with better stress management (r = 0.378, p \u3c .001) and greater enjoyment of physical activity (r = 0.331, p \u3c .001), but not with leisure activity (r = 0.104, p = 0.162). Higher body fat percentage was linked to lower stress management and enjoyment, while greater lean mass correlated positively with leisure activity. These findings highlight the role of self-perception and body composition in shaping psychological well-being and behavior. The results suggest that fostering a positive self-image and healthy body composition could enhance mental well-being and promote physical activity. This research contributes to the broader conversation about mental health and exercise motivation, offering insights for healthcare providers, fitness professionals, and educators working to support student wellness
