Correlation between strength with agility and grip strength in overweight children aged between 7-12 years old

Childhood overweight is a serious health problem in Thailand because it can affect the motor competency of children. The factors of muscle strength and agility played a critical role in motor competency in childhood. Therefore, the easiest and fastest method to detect problems with strength and agility in children are necessary. However, the evidence to support that method in overweight children is still limited. The objective of this study is to examine the correlation between strength and agility, measured by using standardized tests and grip strength among 52 overweight children aged 7-12 years. The strength subtest of the Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2) was used to investigate total muscle strength. The running speed and agility subtest of BOT-2 was used to measure agility for doing activities. A handheld dynamometer was used to examine the grip strength in the dominant hands of children. The study results presented a significant positive correlation between the total point score on strength subtest and grip strength, and the correlation between the total point score of the running speed and agility subtest and grip strength. Moreover, the scale score of strength subtest of BOT-2 and the scale score of running speed, and the agility subtest of BOT-2 positively correlated with grip strength. The correlation between muscle strength and grip strength and the correlation between agility and grip strength were also found in 28 boys and 24 girls. However, a positive significant correlation between the scale score of the strength subtest, the scale score of running speed and the agility subtest and grip strength were presented in boys, but there was no significant correlation in girls. In conclusion, grip strength correlated with total muscle strength and agility in overweight children aged 7-12. Thus, grip strength may be used as primary evaluation among these children because it is easy to use, less time consuming and can be portable. If grip strength scores tend to decrease, muscle strength and agility will be further evaluated.
