Strength Abilities: Estimation of Immediate Training Effect of Strength Loads in Girls Aged 7 Years
The study purpose was to experimentally substantiate technological approaches to estimating training effects of strength loads in girls aged 7 years.
Materials and methods. The study participants were girls aged 7 years (n = 40). The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, theoretical and empirical methods were used: analysis and generalization of scientific and methodological literature; modeling, pedagogical observation and experiment, methods of mathematical experiment planning (2k type FFE).
Results. The study results show that in the proposed matrix of the 22 type full factorial experiment design, the chosen step of variation of factors is sufficient to study the influence of different modes of strength exercises on the dynamics of ITE in girls aged 7 years.
Conclusions. At station 1 (exercises to strengthen arms and shoulders), the ITE in girls aged 7 is most influenced by the interaction between the number of repetitions in a set and the rest interval (x1x2) – 83%, the number of repetitions in a set (x1) – 15%; at station 2 (exercises to strengthen abdominal muscles), it is most influenced by the number of repetitions in a set (x1) – 48.5%, the rest interval (х2) – 48.5%; at station 3 (exercises to strengthen back muscles) – by the rest interval (x2) – 82%; at station 4 (exercises to strengthen leg muscles) – by the rest interval (x2) – 92%. At stations 1–3, to strengthen the ITE, it is necessary to increase the number of repetitions in a set and the duration of the rest interval, at station 4, it is necessary to increase the number of repetitions in a set and to reduce the duration of the rest interval.
