Motor Abilities: Peculiarities of Strength and Strength Endurance Development in Middle-School-Aged Girls in a 4-Week Physical Training Cycle

Abstract

The study purpose was to develop a technology of programming for strength and strength endurance development in middle-school-aged girls in a 4-week physical training cycle. Materials and methods. The study participants were girls of 6th grade (n = 23), 7th grade (n = 20), 8th grade (n = 27). The paper used analysis and generalization of data of scientific and methodological literature, pedagogical testing, and methods of mathematical statistics for processing research results. The study materials were processed by the IBM SPSS 23 statistical analysis software. The following parameters were calculated: arithmetic mean (X); standard deviation (s). The probability of difference in statistical indicators was estimated using the Student’s t-test. Results. The analysis of the study results demonstrated that after using a combined method of strength development (1–6 classes), the experimental group girls showed a statistically significant improvement in results in the set of tests (p < 0.05). After using a circuit training method (7–12 classes), the experimental group girls also showed a statistically significant improvement in results in the set of tests (p < 0.05). During the experiment, the 6th-8th grade girls of the control group showed no statistically significant improvement in test results for most parameters (p > 0.05). Conclusions. When using the combined method of strength development (1–6 classes) and the circuit training method (7–12 classes) in a 4-week physical training cycle, the middle-school-aged girls showed positive dynamics of strength and strength endurance development of shoulder muscles, abdominal and back muscles, leg muscles.
