The purpose of this study was to determine the effect of routine training with the fartlek method in increasing blood hematocrit levels in basketball athletes. This research method used a pre-experiment with the one-group pre-posttest design. The instrument used in this study was a digital hct meter to measure blood hematocrit levels. The results of this study found that the percentage of blood hematocrit after the fartlek training method intervention in Pinisi basketball athletes was 44.94% higher than the average hematocrit level before being given the fartlek training program in Pinisi basketball athletes, which was 41.64%. There was a change with an average value of 3.3% per 100mg of blood. From the results of the analysis, it can be concluded that training with the fartlek run method has a positive effect on increasing hematocrit levels.
