Physical fitness is one of the most important indicators in daily life, supported by various factors including fatigue index and haemoglobin levels. The purpose of this study was to determine: 1) the contribution of fatigue index to physical fitness, 2) the contribution of haemoglobin level to physical fitness, and 3) the contribution of fatigue index and haemoglobin level simultaneously to physical fitness. The research studied belongs to the type of quantitative research with a correlational approach and continued by calculating the amount of contribution of the independent variable (predictor) to the dependent variable (criterion) through the determination index, namely r2 x 100%. Sampling was carried out using purposive sampling technique and the sample amounted to 48 people. The characteristics of this research sample are active sports students aged 18.68 ± 0.86 years, height 165.38 ± 6.71 centimetres, and body weight 56.75 ± 9.70 kilograms. Fatigue Index was measured by Running Based Anaerobic Sprint Test (RAST Test), Haemoglobin Level was measured by Sahli method, and Physical fitness was measured by the Bleep Test. The data analysis techniques used were simple and multiple correlation analysis techniques. Hypotheses 1 and 2 were analysed by simple correlation and regression, while hypothesis 3 was analysed by correlation and multiple regression. Simple correlation and multiple regression analysis, this analysis is used to determine the contribution of fatigue index variables and haemoglobin levels to physical fitness. The results in this study are: 1) Fatigue index contributes to the level of physical fitness by 6.09%. 2) Haemoglobin levels contribute to the level of physical fitness by 9.14%, and 3) Fatigue index and haemoglobin levels together contribute to the level of physical fitness by 16.83%. © 2024 Federacion Espanola de Docentes de Educacion Fisica.
