Recent research:
Across the publications, the work centers on how body composition, physical performance, and psychological factors relate to sports engagement, health behaviors, and clinical practice. The research integrates kinanthropometry, force–velocity profiling, and performance measures in youth soccer and football, examining how muscle mass, fat distribution, and bone density influence strength, speed, and injury risk, while also describing population-level patterns in physical education participation and the impact of COVID-19 on sport-related psychology. Methodologies include cross-sectional and correlational designs, systematic reviews, large-scale demographic analyses, validated questionnaires, and sensor-based performance assessment tools. Findings consistently highlight the importance of muscle mass for strength, nuanced roles of fat distribution and bone density for speed and performance, and the relevance of social determinants (gender, age, food security) on PE participation. Collectively, the work informs training strategies, public health surveillance, and interventions to enhance adherence to physical activity, with implications for integrating robust measurement tools into clinical and educational settings. Future directions emphasize methodological rigor, longitudinal studies, and translational applications to optimize athletic performance and health outcomes.
