Motivación por la musculatura e insatisfacción corporal en usuarios del Zona Gym

Abstract

Currently, physical activity and gym training have gained significant relevance within modern lifestyles, not only as a health-oriented practice but also as a means to achieve socially valued aesthetic ideals. Objective: This study aimed to analyze the relationship between drive for muscularity and body dissatisfaction among users of Zona Gym during the period from March to August 2026. The study was conducted under a quantitative approach, with a non-experimental, cross-sectional, and correlational design. The sample consisted of 56 users of both sexes aged between 18 and 45 years. For data collection, the Drive for Muscularity Scale (DMS), which evaluates the attitudinal and behavioral dimensions associated with drive for muscularity, and the Body Shape Questionnaire (BSQ-18), which measures body dissatisfaction, were administered. Normality tests showed a non-normal distribution of the data, so Spearman's correlation was used. The results showed moderate levels of drive for muscularity and body dissatisfaction, as well as a very strong and statistically significant positive relationship between body dissatisfaction and the behavioral dimension of drive for muscularity, while no significant relationship was found with the attitudinal dimension. It is concluded that body dissatisfaction primarily influences behaviors oriented towards muscle development, constituting a relevant factor for understanding the behavior of gym users. Keywords: motivation, drive for muscularity, body dissatisfaction
