FEATURES OF THE RUNNING DRILLS TECHNIQUE AS A FACTOR DETERMINING THEIR USE IN THE DEVELOPMENT OF PHYSICAL ABILITIES

The aim of this study was to investigate the features of the running drills technique that determine the logic of their use in the development of physical abilities. 7 male students (age 21.0 ± 1.3 years, height 1.82 ± 0.04 m, weight 72.9 ± 5.2 kg) and 9 female students (age 19.4 ± 0.9 years, height 1.71 ± 0.06 m, weight 59.8 ± 6.2 kg) performed a set of running at different speeds and running drills. Two-dimensional video analysis was used (video recording at 240 frames per second, Kinovea 0.9.5 software). One-way ANOVA and related-samples t-test were used to compare sample means. It was found that the drill “ankling drill” was performed by the subjects with the lowest speed among all the running drills, warming-up and fast running considered. The leg in “ankling drill” was placed significantly closer to the projection of the enter of mass (COM), at a significantly largest angle. This suggests the least load in the absorption phase of this exercise. The highest speed among the studied running drills and non-significant differences in the distance from the projection of the COM to the point of contact with the support with fast running were noted in “deer run” and “straight leg running”. This gives grounds to estimate that the absorption loads on the musculoskeletal system in these drills are great. No significant differences were found in the speed in warm-up running, “butt kicks skip”, and “high knee skip”. Moreover, in the named running exercises, the foot was placed on the support at significantly greater angles than in warm-up running, which allows to consider the absorption load on the musculoskeletal system in them to be gentle. The results of the study allow for the justified use of running drills for the development of physical qualities.
