Strength Abilities: Features of Their Development in Girls of Middle School Age

Abstract

The study objective is to determine the dynamics of strength preparedness of middle school girls. Materials and methods. The participants in the study were 6th grade girls (n=20), 7th grade girls (n = 27), 8th grade girls (n = 30). The study used analysis and collation of scientific and methodological literature, pedagogical testing and methods of mathematical statistics for processing research results. The IBM SPSS 23 statistical analysis software was used to process the study materials. The study calculated the following parameters: arithmetic mean of the value (X); standard square deviation (s), mean difference. The probability of difference in statistical indicators was estimated using the Student’s t-test. Results. The analysis of the test results of the 6th-7th grade girls showed statistically significant differences in the set of tests (p<0.05). For the 7th grade girls, the largest increase was observed in the strength indicators of shoulder muscles, abdominal and back muscles, strength indurance of leg muscles. For the 6th-8th grade girls, statistically significant differences were observed in the strength and strength endurance indicators of shoulder muscles, abdominal and back muscles, leg muscles, speed qualities (p<0.05). The study did not observe any statistically significant differences in the set of tests (p>0.05) for the 7th-8th grade girls, there was only an increase in the strength endurance indicators of leg and back muscles. Statistically significant differences were observed in the frequency of arm movements test (p<0.001). Conclusions. The girls of middle school age demonstrate a positive dynamics in the development of motor preparedness. The largest increase is observed in the strength and strength endurance indicators of shoulder, abdominal, back, and leg muscles.
