Assessing Change of Direction and Neuromuscular Power in Children: Insights From an Allometric Approach in Mediterranean Youth

Abstract

This study evaluates the physical performance of children aged 8–10 from northeastern Mediterranean regions (Italy, Türkiye, and Croatia) with a focus on change of direction (COD) ability and neuromuscular power through an allometric approach. A total of 890 children participated, undergoing assessments including the 4 × 10 m shuttle run for COD and the standing broad jump (SBJ) for explosive leg strength. An allometric scaling model was used to control for variations in body size, allowing for an analysis that accounts for growth factors like height and weight. Results show that height positively contributes to shuttle run performance, while increased body mass has a negative impact. The inclusion of SBJ in the model indicated that neuromuscular power further enhances COD ability, particularly in a balanced ecto-mesomorphic body type. Regional differences were also noted, with Italian and Croatian children outperforming Turkish peers, suggesting environmental or cultural influences. The findings underscore the importance of promoting strength and motor skills in youth physical education to enhance agility and overall fitness. These results offer valuable insights for designing tailored training programs that support balanced physical development in children.
