Effects of two different programs of modern sports dancing on motor coordination, strength, and speed.

摘要

This study aimed to determine the effects of two different programs of modern sports dancing on coordination, strength, and speed in 60 beginner-level female dancers, aged 13 and 14 yrs. The subjects were divided into two experimental groups (E1 and E2), each numbering 30 subjects, drawn from local dance clubs. In order to determine motor coordination, strength, and speed, we used 15 measurements. The groups were tested before and after the experimental programs. Both experimental programs lasted for 18 wks, with training sessions twice a week for 60 minutes. The subjects from the E1 group trained according to a new experimental program of disco dance (DD) modern sports dance, and the E2 group trained according to the classic DD program of the same kind for beginner selections. The obtained results were assessed by statistical analysis: a paired-samples t-test and MANCOVA/ANCOVA. The results indicated that following the experimental programs, both groups showed a statistically significant improvement in the evaluated skills, but the changes among the E1 group subjects were more pronounced. The basic assumption of this research was confirmed, that the new experimental DD program has a significant influence on coordination, strength, and speed. In relation to these changes, the application of the new DD program was recommended for beginner dancers.
