RELATIONSHIP BETWEEN AN-AEROBIC THRESHOLD, LACTIC ACID, AND VO2 MAX. DURING THE GENERAL PREPARATION PERIOD WITH THE LONG DISTANCE RUNNING PERFORMANCE OF SEA GAMES ATHLETES

Abstract

This study aims to examine the significant relationship between an-aerobic threshold, lactic acid, and VO2 Max during the general preparation period and the long-distance running performance of SEA Games athletes. The method used in this research is a descriptive method which provides an overview of the variables studied and does not provide research treatment to the sample. The research design used is a correlational design by correlating or connecting the variables studied. The sample in this study was 6 athletes from the 2023 Cambodia SEA Games Indonesian National Training Center in long distance running. Instruments in the form of tests carried out at the FPOK UPI Sport Science Laboratory were given once to samples in December 2022 in the form of: a treadmill to measure VO2 max, an anaerobic threshold indicator in the form of a Polar to measure the anaerobic threshold, and a lactate meter to measure lactic acid. Data in the form of long distance running times for each athlete in the Athletics Championship competition held in November-December 2022 in Thailand and the Athletics Invitation and National Selection SEA Games held in January 2023 in Jakarta were collected. Data analysis was carried out using SPSS version 24 software. The results showed that an-aerobic threshold, lactic acid, and VO2 Max during the general preparation period had a significant relationship with the long-distance running performance of SEA Games athletes. Based on the conclusions above, this research provides implications for lactic acid, an-aerobic threshold, and VO2 Max. The periodization period for the general preparation stage is an important thing that long distance running athletes must pay attention to.
