The purposes of this study were to provide basic the data about standard of fatigue that occurs due to simple repeated keyboard work on a computer. Fifteen subjects (students of OO University) being in this study (7 male, 8 female). The subjects typewrote a long article of Hancom Taja Gyosil, their mean typing speeds were recorded, and they were divided randomly into three groups according to typing speeds. And typing speeds were increased at the rate of 120%, 140%, 160% of mean typing speeds in each groups, caused muscle fatigue artificially. Before and after the experiment, grip strengths were measured and Box and Block Test (hereinafter referred to as “BBT”) was performed respectively. The results were as follows;
1. In group of 299 types/min and less, there was not statistically significant difference in grip strength between before and after the typewrite, BBT score showed significant differences at 120%, 140%, 160%(p<0.05).
2. In the group of 300~350 types/min, there were statistically significant difference in grip strength between before and after the typewrite, at 120%, 160%, BBT score showed ignificant differences at 100%, 140%, 160%(p<0.05).
3. In the group of more than 350 types/min, there were statistically significant difference in grip strength between before and after the typewrite at 140%, 160%, BBT score showed significant differences at all experiments(p<0.05).
Future study will be needed to complement factors about grip strength and typing speed. With recent investigations of cumulative trauma disorders, our results would be use as the basic data that prevent and manage to computer users' that.
