【 摘 要 】

This study investigated the response of 2,3-DPG concentrations infemale college students after a 7 week aerobic training program at75% of Max H. R.. The 22 Ss, 12 experimental and 10 control volunteered to participate in pre and post-treatment Max VO2 testswith blood samples drawn before and after completing each exhaustiverun. The blood samples were tested for hematocrit, levels ofhemoglobin, lactic acid and 2,3-DPG. The data were analyzed by atwo-way ANOVA with repeated measures with significant interactionsfurther analyzed by a Scheffd post hoc test. There was no sig diff(p < .05) in hematocrit pre to post-treatment while blood lactateand hemoglobin exhibited a significant decrease (p < .05). Asignificant decrease (p < .05) was demonstrated in 2,3-DPG concentrationsin the experimental group after training witch accompanied thesignificant increase in Max VO2 values of the same group. Nosignificant change was found in Max VO2 levels of the control groupwho demonstrated a significant increase (~2.05) in 2,3-DPG levelsafter training. It was concluded that 2,3-DPG is a mechanisminvolved in the O2 transport system, but the magnitude and limitationsit produces on O2 delivery during exercise is not clearlyunderstood from the results observed in this study.
