The Effect of 1:1 Interval Training and Flexibility on 50 Meter Speed Bifins Numbers in Female Athletes at Octopus Diving Club, Semarang City

Abstract

The problem in this research is the lack of bifins speed ability in the female athletes of the Octopus Diving Club, Semarang City. The aim of this research was to determine the effect of 1:1 interval training on speed in the 50 meter bifins number and to determine the correlation between flexibility and speed in the 50 meter bifins number in female athletes at the Octopus Diving Club, Semarang City. This type of research uses an experimental method, one group pretest-posttest. The population is all athletes from the Octopus Diving Club, Semarang City, with a total of 25 athletes. The sampling technique is purposive sampling. The criteria for determining the sample include being active in training, being female, having a diving certificate or Diving Athlete Identification Number (NIAS), mastering bifins techniques, not being sick, and being willing to follow the rules of the treatment being applied. The sample that met the criteria was 6 people. Data was collected through a 50 meter bifins speed test and a sit and reach test. Then analyzed using paired sample t-test statistics and product moment correlation. 50 meter variable speed test results, bifins number, Sig value. (2-tailed) was 0.001<0.05 and there was an increase in speed of 50 meters in the bifins number, while testing the flexibility variable produced a Sig value. (2-tailed) of 0.370>0.05. It was concluded that 1:1 interval training had a significant influence on increasing the speed of 50 meter bifins, and flexibility had no significant correlation with the speed of 50 meter bifins of Octopus Diving Club female athletes.
