The effect of interval training on 100-meter running speed in club tub jar aru female sprinter athletes

Abstract

This study aims to determine the effect of interval training on 100-meter running speed in female sprinter athletes Club Tub Jar Aru. The method used by the experiment was to determine the effect of the independent variable (interval training) against the dependent variable (100-meter running speed) under controlled conditions. The entire population of 15 people was also sampled (Census research). The data sources in this study were collected through 100-meter running test data before and after treatment. The test results from the table "t" with DF = n-1, i.e., = 15-1 = 14, show that with df of 14 at a significant level of 5% obtained, t-table. = 1,761 and 1% = 2,624. Because t-observation.is greater than the t-table. Thus, significant levels of 5% and 1% of the alternative hypothesis are accepted, while the null hypothesis is rejected. This means that at a significant level of 5% and 1%, there is a positive influence between the independent and dependent variables in the form of a significant increase in running speed in Club Tub Jar Aru female sprinter athletes.
