Significance of Hand Grip Strength Measurement for Children Aged 5-6

Abstract

[Objective] To confirm the significance of hand grip strength measurementfor infants, the hand grip strength of children aged 5-6 was measured and comparedwithvalues representing other motor skills. [Subjects] The measurement involved 408 (211 males and 197 females) healthy children aged 5-6. [Methods] After measuring the height, weight,and hand grip strength, the 5 motor skill tests for infants developed by the Ministry of Education, Culture, Sports, Science, and Technology were conducted to analyze their relationships with the hand grip strength. [Results] Malesʼand femalesʼmean hand grip strengths were 8.5 ± 2.2 and 8.1 ± 2.2 kg, but, sex difference was small. Single correlation analysis revealed small correlations of the hand grip strength with the height, body, and results of the following tests: 25-meter run, standing broad jump, and body support time.
