Trends in Physical Fitness in Children and Adolescents Within the Past 18 Years (DONALD Study).

Objective: To evaluate the trends in physical fitness in children and adolescents.

Method: The present study focusses on a longitudinal analysis of the single two-legged jump (S2LJ) from children and adolescents, who participated in the DONALD study from 2004 till 2022. P /body mass (power, surrogate for muscular performance), V (bounce speed, surrogate for coordination), F /body mass (force, surrogate for muscular strength) and (Nerve-Muscle Index, surrogate for jump efficiency) were examined by linear mixed models and propensity-score(PS)-matching analysis.

Multivariable reference centiles for maximum grip strength in childhood to young adults.

Objectives: Maximum grip strength (mGS) is a useful predictor of health-related outcomes in children and adults. The aim of the study was to generate sex- and age-adjusted reference centiles for mGS for children, adolescents and young adults, while adjusting for body height and body mass index (BMI).

Methods: A retrospective analysis of longitudinal data from children and young adults participating in the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study (single center, open cohort study) from 2004 to 2022 was conducted.
