This study aims to explore the relationship between erythrocyte levels, hemoglobin, VO2Max, and hematocrit in individuals who undergo a High-Intensity Interval Training (HIIT) program for 8 weeks. HIIT is known to be effective in improving cardiovascular fitness, which is measured through an increase in VO2Max. A total of 30 active students who met the inclusion criteria participated in this study. Hematological parameters and VO2Max were measured before and after the intervention. The results showed that VO2Max increased significantly by 21.46% (p < 0.05), while hemoglobin and erythrocyte levels increased only slightly and insignificantly (p > 0.05). Hematocrit decreased by 1.5% (p > 0.05). Correlation tests showed a significant relationship between changes in hemoglobin and erythrocyte levels with hematocrit (p < 0.05), but no significant relationship was found between increased VO2Max and changes in hemoglobin and erythrocyte levels (p > 0.05). These findings indicate that although HIIT is effective in increasing aerobic capacity, the body's physiological adaptation to intensive exercise is more complex and does not necessarily correlate directly with changes in haematological parameters. More research is needed to understand the mechanisms behind these outcomes and other factors that may influence the hematological response to HIIT.
