Dynamometric measurements for 11-year-old boys
MOLNÁR, Matěj
The aim of the bachelor's thesis is to assess the results of measurements with three devices evaluating the strength of the muscles of the upper limb (Collin, Takei and the Vernier school system). The group of probands consisted of 37 boys aged 11 years from the Vysočina region. In addition to muscle strength, somatic dimensions such as body height, body weight and skin fold over the triceps were also measured. Compared to the norm for the Czech population (VI. Natiowide Anthropological Survey 2001), the average values of body height (p = 0.01) differ statistically significantly in favor of our group, the values of body weight (p = 0.95), Body Mass index (p = 0.11) and skin fold over the triceps (p = 0.58) did not differ statistically significantly. The student's t-test revealed statistically significant differences between the mean values of the group in the measurements of the Takei, Vernier and Collin instruments in favor of the Takei dynamometer. Correlation analysis showed that the values of hand grip strength between Takei-Vernier (p = 0.00) and Takei-Collin (p = 0.00) correlated statistically significantly. However, for Takei and Vernier (first measurement, right hand, r = 0.81) correlated more closely than with the Takei and Collin instruments (first measurement, right hand, r = 0.51).
