CrossFit® and Its Influence on Health Behaviors, Functional Capacity, and Psychosocial Outcomes: An Explorative Study of Gender Differences in Athlete Perspectives.

Abstract

Objectives: This explorative study aimed to evaluate athletes' perceptions of how CrossFit^® affects physical, psychological, and social well-being, exploring gender differences. CrossFit^® is a high-intensity functional training modality aimed at enhancing overall fitness and health. Limited research has explored its perceived impact on broader aspects of well-being, particularly considering gender differences. Methods: A total of 202 participants (age 34.3 ± 10.0 years) with at least 6 months of CrossFit^® experience completed an online self-reported questionnaire not previously published but created following published guidelines. The questions explore athletes' perceptions of their improvements in physical fitness, injury occurrence, and the effects on mental well-being. Statistical analysis included descriptive statistics and parametric and non-parametric tests to investigate gender differences. Results: In total, 81.2% of participants perceived improvements in strength, while 83.2% reported enhanced aerobic capacity. Significant body composition improvements were noted by 68.3% of the sample, and 87.6% reported changes in eating habits. Injury incidence was lower among women (30.2%) than men (45.3%) (p = 0.02). Regarding psychological outcomes, 95% of respondents indicated a reduction in stress levels, 73.3% reported better sleep quality, and over 90% perceived improvements in self-esteem and daily energy. Furthermore, 98.5% of participants formed new social connections through CrossFit^®, with 79.2% acknowledging a positive impact on social relationships. No significant gender differences were found across most psychological and social outcomes. Conclusions: CrossFit^® is perceived positively by participants, with similar views across genders, except for injury rates. It enhances physical fitness, mental health, and social well-being, with high training adherence and relatively low injury risk.
