Children underwent assessments for aerobic and anaerobic fitness, flexibility and hand-grip strength. Results suggest that the inverse Ponderal index and not BMI is the most appropriate body-shape indicator associated with running and jumping activities. Height was negatively associated with flexibility, but both height and weight were positively associated with hand-grip strength. In conclusion, allometric models provide a valuable insight into the most appropriate body size and shape characteristics associated with children's physical performances and at the same time ensure valid inference when investigating group/population differences (e.g., between gender and maturation status).enAllometric modelsBody size characteristicsBody shape characteristicsChildrenPhysical performanceJournal articlePediatric exercise science
