Insights
Handgrip strength in children is linked to body measurements and hand size. Boys generally have stronger grips than girls, with the dominant hand being sturdier.
Area of Science:
- Pediatric health assessment
- Anthropometry and biomechanics
Background:
- Handgrip strength is a key indicator of overall health and hand function in children.
- It is significantly influenced by anthropometric factors and hand dimensions.
Purpose of the Study:
- To evaluate handgrip strength in school children.
- To determine the association between handgrip strength and anthropometric measures, hand circumference, hand span, and hand length.
- To compare strength in dominant and non-dominant hands.
Main Methods:
- 133 school children aged 6-12 years participated.
- Measurements included anthropometrics, hand circumference, hand span, and hand length using a tape measure.
- Handgrip strength was measured using a Jamar hand-held dynamometer.
Main Results:
- Significant differences in handgrip strength were observed between boys and girls.
- The dominant hand exhibited greater strength than the non-dominant hand in both genders.
- Age, BMI, hand circumference, hand span, and hand length showed a strong positive correlation with handgrip strength (p < 0.01).
Conclusions:
- The study established reference values for handgrip strength in children aged 6-12 years.
- Significant correlations were found between handgrip strength and various hand dimensions.
- Findings can guide the interpretation of handgrip strength measurements in pediatric populations.
Background:
Handgrip strength is considered an important interpreter of general health, and hand functions in children. It is mainly influenced by anthropometric determinants and hand dimensions.
Objective:
To assess the handgrip strength and their association with anthropometric determinants, hand circumference, hand span, and hand length among school children in both the dominant and non-dominant hand.
Methods:
Anthropometric measurements, hand circumference, hand span, hand length, and grip strength measurements were obtained from 133 school children of both genders aged 6-12 years. A Jamar hand-held dynamometer was used to measure handgrip strength and the hand dimensions with a tape measure in cm.
Results:
Significant differences were found between the handgrip strength among boys and girls. The dominant hand was found to be sturdier than the non-dominant hand in both genders. We also found a significant correlation of anthropometric determinants and hand dimensions with handgrip strength. Age, BMI, hand circumference, hand span, and hand length had a strong correlation with grip strength (p < 0.01).
Conclusions:
The study revealed the reference values and concluded its correlations with hand dimensions among school children aged 6-12 years and this information can serve as a manual for interpretation of handgrip strength measurements in children.
