SOME THOUGHTS CONCERNING ANEMIA AND ITS PHYSICAL EXERCISE CAPACITY OF 18-YEAR-OLD FEMALES : 2. From the Viewpoint of Hemoglobin Values and 12 Minutes Running Records(Natural science)

P(論文)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_, 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
