Handgrip Strength and Anthropometric Characteristics of Children and Adolescents in Türkiye

Abstract

Muscle strength capacity and anthropometric characteristics vary across populations, limiting the direct applicability of global ergonomic design standards to local user groups. This study aimed to establish normative reference values for maximal handgrip strength (HGS) and selected anthropometric measures in Turkish children and adolescents aged 6-17 years. A pilot study involving 120 participants was conducted to determine the required sample size for the main cross-sectional study, which included 459 healthy volunteers (232 girls and 227 boys) residing in İstanbul. HGS was measured for both dominant and non-dominant hands using a calibrated digital Jamar dynamometer in accordance with the American Society of Hand Therapists protocol. Height, body mass, hand length, and hand width were also recorded. Statistical analyses (ANOVA, t-tests, and correlation analysis) showed that HGS increased with age in both genders, with boys demonstrating higher strength values across all age groups, except 12-year age group. Grip strength was also strongly associated with height, body mass, and hand dimensions. These findings provide population-specific reference values that can support the ergonomic design of products and environments intended for children and adolescents in Türkiye.
