Reliability of the PREFIT fitness-test battery in Chilean preschoolers.

ABSTRACT:

Introduction

This study explores the test-retest reliability of the FITness in PREschoolers (PREFIT) battery, including cardiorespiratory fitness [20 m shuttle run test (SRT)], upper-body muscle strength (handgrip strength), lower-body explosive strength (standing long jump), speed (4 × 10 m shuttle run), and static balance (one-leg stance), in Chilean preschoolers considering weight status, sex, and age.

Methods

The study included 171 Chilean preschoolers (5.4 ± 0.7 years). The PREFIT battery was applied using a test-retest design within 7-10 days between evaluations, and weight status was determined using BMI z-scores (ClinicalTrials.gov: NCT04269135). Statistical analyses included test-retest differences, Lin's concordance correlation coefficient, Cohen's effect si
