Intensive and Extensive Interval Training; Which is Better Against Vo2max Football Athletes?

Abstract

This study aimed to determine the difference between intensive and extensive interval training on the VO2Max of football athletes. This type of research is an experiment. The sample used was football athletes at LPSB Mutiara Purwokerto, totalling 14 athletes with an age range of 13-15 years. Samples were divided into two groups based on pretest scores using ordinal pairing. The instrument for measuring VO2Max uses the intermittent Yo-Yo test. Data analysis techniques include descriptive analysis, prerequisite tests (normality and homogeneity tests), and hypothesis testing using paired sample tests and independent sample tests. The analysis used SPSS 23 software. The results showed (1) a significant effect of intensive interval training on the VO2Max of football athletes. The magnitude of the increase in VO2Max in soccer athletes after being given intensive interval training was 5.07%. (2) There is a significant effect of intensive interval training on the VO2Max of soccer athletes. The magnitude of the increase in VO2Max in soccer athletes after being given extensive interval training was 12.54%. (3) There is a significant difference between intensive and extensive interval training on the VO2Max of football athletes. The mean difference in the increase in VO2Max of the intensive and extensive interval group soccer athletes was 2.02, so the extensive interval training group was better than the intensive interval training group on the VO2Max of soccer athletes.
