Sažetak
The aim of this paper was to find the correlation between two variables of explosive power and their connection with the competitive successfulness of boys in alpine skiing. The sample comprised 24 young boys aged 12 and 13. The explosive power was analyzed by the standing triple jump (3SM) and the standing long jump (SDM). The correlation of the two independent variables of the explosive power space was statistically significant (r = 0.80). The two variables were also statistically significantly connected with the actual competitive successfulness of the tested category (35M - r = 0.52, SDM -r = 0.47). The high value of the multiple coefficient of correlation between the two mentioned tests and the criterion variable was calculated by regression analysis (Mult R = 0.53), and proved to be statistically significant Sig F = 0.03). Taking into consideration the structure of movement in alpine skiing, the significance of using both tests for the measurement of explosive power of young alpine skiers simultaneously seems quite doubtful. It was found that, regarding similar latent dimensions in the background of both independent variables, in the future it would be sounder to use only the standing triple jump test for analyzing explosive power, which is also by its structure closer to the movement structure in alpine skiing.
