5. Timing does not effect to each group in the changes of HGB and HCT.
t.-fn the comparison between before and after the experiments in the changes of MCV, cold therapy, group showed significant measurement. And in the comparison between before and after one hour the experiment in
---the changes of MCV, cold therapy group showed significant measurement. The experimental group -I and 3" showed the distinctive differences in Scheffe´ s analysis after the fact(p<.05).
7. In the comparison between before and after one hour experiments in MCV changes, the cold therapy group had significant differences(p<.05).
8. There were no significant differences between before and after the experiments in MCHC changes.
9. In the comparison between before and after one hour experiments in PLT changes, cold therapy group had significant changes(p<.05) and there were no differences among three group.
