Effect Combination of HIIT with Recovery Model on VO2max Quality and Monitoring of Heart-Rate Recovery

This study aims to analyze the effect of differences resulting from combination HIIT with recovery models in active and passive forms on quality VO2max monitoring heart-rate recovery. was designed using a quasi-experimental design, 30 participants participated voluntarily which further divided into three groups: HIIT-PP experiment (n:10; Age: 21.0±0.82; Weight: 67.2±13.6; Height: 1.68±0.07), (n=10; 21.1±1.20; 64.9±6.07; 1.68±0.04), control group 21.09±1.29; 69.3±5.46; Height 1.69±0.05). research instrument uses Multistage Fitness Test (MFT) Heart-Rate Monitoring. The procedure for analyzing statistical data used Analysis Variance (ANOVA) test p-value <0.05. results showed that parameter between experimental groups significantly improved (HRM, HRR 2min, 5min, 10min). can conclude eight weeks resulted change heart rate
