This study aims to identify the relationship between the anaerobic phosphagen capacity and heart rate recovery curve; heartbeat is recorded immediately after the physical load, after 1 minute of the physical load, and after 3minutes of physical load. The study also aims to identify the relationship between anaerobic lactic capacity and heart rate recovery curve; the heartbeat is recorded immediately after the physical load, after 1 minute of the physical load, and after 3 minutes of physical load. The study uses a descriptive approach to find correlational relations of the problem. This study's sample population was chosen from the Samarra University college football players. The sample consisted of (80) players, randomly selected. Statistical methods were used by the statistical software (SPSS), the percentages, arithmetical mean, standard deviation, simple correlation coefficient, and torsion modulus. The researchers concluded that a relationship between the anaerobic phosphagen capacity and heart rate recovery curve existed immediately after the physical load, after 1 minute of the physical load, and after 3 minutes of physical load. The researchers also concluded that a relationship between the anaerobic lactic capacity and heart rate recovery curve also existed immediately after the physical load, after 1 minute of the physical load, and after 3 minutes of physical load
