“…The gradual difference in the HGS/MT ratio may associate with the development of the nervous system, which supports the results of the previous studies [10,11]. A study reported that children aged 5-6 could precisely adjust the different levels of HGS production as directed by an investigator, but children aged 3 could not do so at all [8]. The results from the present and previous studies together suggested that the levels of voluntary muscle activation, i.e., motivation and maturity (i.e., ability to receive instruction) during maximal HGS measurement are similar among 4.5 to 6.5 years of age.…”

“…One of these methodological difficulties is the fact that it is difficult to determine whether children understand the verbal instructions given to them. In this regard, it has been pointed out that the cognitive development of 3-year-old children may not be able to fully understand the instructions regarding the generation of strength [8]. Another difficulty is to determine the level of voluntary activation (motivation) during strength tests which is an important factor in measuring maximum muscle strength.…”

The Measurement of Strength in Children: Is the Peak Value Truly Maximal?

It is unclear whether the measurement of maximum muscle strength in younger children can be performed accurately due to factors such as motivation and maturity (i.e., the ability to receive instruction). If there is a large change in a ratio between muscular strength and size from the youngest to the oldest, then this might provide some indication that the youngest may not have been able to voluntarily activate their muscles for reasons mentioned previously. The purpose of this study was to observe the ratio between handgrip strength (HGS) and forearm muscle thickness (MT) across differing ages in younger children. A total of 1133 preschool children (559 boys and 574 girls) between the ages of 4.5 and 6.5 years had MT and HGS measurements and calculated the ratio of HGS/MT (kg/cm). Linear regression was used to assess the impact of age and sex on the dependent variables of MT, HGS, and the HGS/MT ratio. The HGS/MT ratio increases moderately from age 4.5 to 6.5 in both boys and girls. However, the difference in this ratio was small between the age ranges in this sample. Our results indicate children as young as 4.5 may be accurately measured with the handgrip strength test.
