Introduction. Anthropometric characteristics and physical activity (PA) levels are often considered as potential variables that can be significantly correlated with specific motor abilities. Aim of Study. The aim of this study was to evaluate the relationships between anthropometric characteristics and motor abilities with the use of a methodological approach that is rarely applied in physical culture sciences. The correlations between body mass, body height, BMI and PA levels vs sequential power decrease in successive minutes of the 3-Minute Burpee Test (3-MBT) were analyzed. Material and Methods. The study involved 359 full-time university students aged 19-22, including 163 male (20.4 ± 0.67 years) and 196 female (20.4 ± 0.65 years) participants. Anthropometric characteristics (body mass, height and BMI), PA level (MET units) were measured according to standardized guidelines before the test. The participants’ strength endrance were evaluated with the use of the 3-MBT. The results were processed statistically by calculating third-order partial correlation coefficients. Results. Raw score correlation coefficients were statistically significant (p-values: 0.05-0.01), excluding body height which was not bound by significant correlations with the number of cycles completed by women in each minute of the 3-MBT and the number of cycles completed by men in the first minute of the 3-MBT. However, the third-order partial correlation analysis demonstrated that PA level was the only independent variable that was significantly correlated with the results scored in the entire 3-MBT and in successive minutes of the test. In both sexes, the lowest values were observed in the first minute, and they were considerably higher in the second minute of the test. Conclusions. In the group of the analyzed variables, only PA levels significantly influence the strength endurance of moderately physically active young women and men during the 3-MBT.
Introduction. Anthropometric measurements and the BMI are taken into account in the process of developing physical fitness tests for children. Aim of Study. The aim of this study was to describe the relationships between the anthropometric characteristics (body mass, body height, length of lower and upper limbs), BMI and speed abilities of preschool boys and girls performing the 8-second skipping with hand clapping (8-s SHC) test. The increase in HR during the test was also determined. Material and Methods. The test involved 60 girls and 57 boys aged 68.2 ± 11.33 months (min. – 56, max – 89). Their body mass, body height, length of lower and upper limbs and BMI were determined, and their speed abilities were evaluated with a 8-s SHC test. The participants’ HR was measured before and after the test, and the exercise-induced increase in HR was calculated. The basic statistics were determined for all evaluated parameters and the coefficients of correlation between anthropometric features, HR, and the number of claps during the test were calculated. Results. Among the analyzed parameters, only body mass and BMI were significantly higher in boys than in girls. Mean HR increased during the 8-s SHC test in both girls and boys (to 149.40 and 152.9 bpm, respectively). The number of claps during the 8-s SK test increased significantly with an increase in the values of anthropometric measurements. Significant correlations between the analyzed parameters were not determined only for BMI and heart rate after the 8-s SK test. Conclusions. Anthropometric characteristics such as body mass, body height, length of lower and upper limbs significantly influenced the speed abilities of kindergarteners performing the 8-s SK test, whereas BMI was not significantly correlated with the results of the test.
