This study investigated the response of 2,3-DPG concentrations in female college students after a 7 week aerobic training program at 75% of Max H. R.. The 22 Ss, 12 experimental and 10 control volunteered to participate in pre and post-treatment Max VO2 tests with blood samples drawn before and after completing each exhaustive run. The blood samples were tested for hematocrit, levels of hemoglobin, lactic acid and 2,3-DPG. The data were analyzed by a two-way ANOVA with repeated measures with significant interactions further analyzed by a Scheffd post hoc test. There was no sig diff (p < .05) in hematocrit pre to post-treatment while blood lactate and hemoglobin exhibited a significant decrease (p < .05). A significant decrease (p < .05) was demonstrated in 2,3-DPG concentrations in the experimental group after training witch accompanied the significant increase in Max VO2 values of the same group. No significant change was found in Max VO2 levels of the control group who demonstrated a significant increase (~2.05) in 2,3-DPG levels after training. It was concluded that 2,3-DPG is a mechanism involved in the O2 transport system, but the magnitude and limitations it produces on O2 delivery during exercise is not clearly understood from the results observed in this study.
