The Effectiveness of Speed Play and Fartlek Methods in Improving VO₂Max of Futsal Athletes

This study aims to determine the effectiveness of speed play and fartlek training methods in improving VO₂Max among futsal players at SMA Labschool Bandung. Method: This research employed an experimental method with a two-group pretest-posttest design. The sampling technique used was total sampling. The sample consisted of 14 futsal athletes from SMA Labschool Bandung, aged between 15 and 17 years. Data were collected using the Multistage Fitness Test (MFT) or Bleep Test to assess VO₂Max levels. Following the initial data collection, the samples were grouped using the A-B-B-A method to create two homogeneous groups. For data analysis, validity and reliability tests were conducted, starting with Pearson correlation and Cronbach’s alpha, followed by a t-test. Results: The results showed that the t value (5.164) > t-table (2.178), indicating a significant difference between the effects of the speed play and fartlek training methods on VO₂Max. Conclusion: The findings demonstrate that the fartlek method is more effective than the speed play method in improving VO₂Max levels among futsal athletes.
