The subjects of this study were students at a physical education university. The degree of subjective fatigue (DSF), physical condition score (PCS), and hemoglobin (Hb) concentration were measured 12 times in a single day from 7:00 to 21:00. The Hb concentration had a maximum value of 14.2±1.0g/dL and a minimum value of 11.6±1.0g/dL in males (n=5) and a maximum value of 15.6±0.3g/dL and a minimum value of 13.5±0.2g/dL in females (n=9). Although the average Hb concentration was higher in males than in females, the difference between maximum and minimum in females was significantly larger than that in males (p<0.05). In males, we detected reduced levels of Hb in 69% of the subjects with low PCS. In females, we detected reduced levels of Hb in 57% of the subjects with low DSF. Results suggested that the relationship between Hb, DSF, and PCS is sex‐specific.
