Muscular fitness, body composition and physical self-perception in adolescents

Journal Article


Abstract


  • The primary aim of this study was to investigate gender differences in the relationship between muscular strength, body composition,

    and physical self-perception in adolescents. Participants (n = 106, age 15.0±0.7 years, 51% boys) completed the following assessments:

    height and weight, bio-electrical impedance analysis (body fat %), muscular strength (1RM bench press and leg press), and the Children’s

    Physical Self-Perception Profile. Bivariate correlations were examined and mediation analysis was used to explore if physical self-perception

    sub-domains mediated the relationship between muscular strength/adiposity and overall physical self-worth. Among boys, physical self-worth

    was associated with absolute total strength (r = 0.36, p < 0.01), but not with body fat%(r =−0.11, p = 0.44), or relative total strength (r = 0.21,

    p = 0.13). In adolescent girls, physical self-worth was associated with body fat%(r =−0.42, p < 0.01), relative total strength (r = 0.40, p < 0.01)

    but not absolute total strength (r = 0.07, p = 0.62). In boys, perceived physical strength mediated the relationship between absolute muscular

    strength and physical self-worth. Relative muscular strength was not associated with perceived strength (p > 0.05) in girls and the test of the

    mediated effect was non-significant (p > 0.05). Perceived body attractiveness was found to mediate the relationship between body fat % and

    physical self-worth among boys and girls. Physical self-worth is associated with different components of health-related fitness in adolescent

    girls and boys. Mediation analysis can be used to provide insights into the complex interrelationships between variables.
