Comparison of 2,3-DPG levels in college women pre and post-training
Abstract
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.
