Is the peak value truly maximal when measuring strength in young children? An updated study

Objective: There is a lack of information about whether preschool-aged children are providing maximal attempts when measuring strength. Therefore, this study aimed to investigate the association between handgrip strength and fore arm muscle size across age ranges, including three years old. Design Methods: A total 166 preschool (87 boys 79 girls) ages 3.5 6.5 were recruited from local kindergarten with cooperation their parents. Maximum voluntary (HGS) was measured right hand using Smedley dynamometer. Muscle thickness (MT-ulna) B-mode ultrasound at anterior forearm arm. Results: All beta (B) coefficients unstandardized. statistically significant relationship (r = 0.525) MT-ulna HGS [B 0.751 (95% CI: 0.563, 0.938) p < 0.001]. However, did not depend upon [MT-ulna*Age in months: B -0.0033 -0.01, 0.01), 0.658]. In other words, vary by months. This also true expressed (MT-Ulna*Age years: 0.697). Conclusion: Our results indicated that baseline might provide suggestive evidence maximally contracting. we acknowledge correlation analysis has limitations. Further research needed observe these variables through longitudinal studies confirm study.
