V. E. EDGERTON, et al. reported that physical work capacity is closely related to Hb concentration. Similar reports are shown by M. DUKE, et al., B. J. SPROUL et al. and C. T. A. D_<AVIS>, et al. They studied severely anemic or moderately anemic subjects. In this report, the subjects with marginal Hb concentration were observed and 221 subjects aged 18-Yeare-old famale divided into 5 groups according to their Hb concentration. Group A : Anemia (Hb<12.0 g/dl) N : Normal (Hb;≧12.0 g/dl) N1 : Normal. 1 (12≦Hb<13.0 g/dl) N2 : Normal. 2 (13≦Hb<14.0 g/dl) N3 : Normal. 3 (14.0 g/dl≦Hb) The purpose of this study is to examin its relationship between Hb value and physical work capacity. With the groups, statistical comparison has been made on each physical work capacity of step test and 12 minutes running. The results were as follows ; 1 Significant differences could be found in physical work capacity between A and N group. (P<0.05) 2 Significant differences was to be found between A and N2 group in 12 minutes running records. (P<0.05) 3 There was no significant differences to be found in physical work capacity among group N1, group N2 and group N3. 4 No significant differences could be found between physiqe and physical work capacity 5 There was a significant co-relation to be found between Hb concentration and 12 minutes running records.
