Abstract

The Effect of Work Position on Fatigue on the Arm Muscles of Computer Operator This research is intended to find out the effect of work position on fatigue on the arm muscles of computer operator. This is an experimental research using pre-post test control design for different samples and one group pre post test design for the same samples. The population were 31 operators of computer services at Tamalanrea district, in Makassar. The criteria of the samples were 25-40 years old, male, 1 year work experience, weight 50-70 kgs, length of arms 65-75 cros, height 50-70 cros, muscle contraction capacity was within the same range (statistic 30-40 kgs, dynamic 30-45 second), good physical fitness, duration of night sleep was more then 6 hours and not suffering from any disease which might hinder the research. 21 Samples were taken through simple random sampling and then random allocation was done into three different group treatments and 7 samples of the same kind. The result of static contraction capacity measurement and dynamic arm muscles were tested using anova and anacova test for different samples and paired sample t test for the same sample. The findings of the research are that there was a significant difference (p<0,05) between static and dynamic contraction capacity before and after 30 minute-typing in the group construe of t test paired sample, after typing at the position of 0-20°, static 36,29 'kgs (SD=1,11 kg), dynamics 33,86 seconds (SD=0,69 seconds), 40-60°, static 36,14 kgs (SD 0,90 kg), dynamic 33,86 seconds (SD=0,90 second). However there is no significant difference at the position 20-401, static 36,86 kgs (SD=0,90 kg), dynamics 35,00 seconds (SD=1,15 seconds). In different samples among the group with anova and anacova tests there was no significant difference (p>0,05) after typing at the position 0-20°, static 36,71 kgs (SD=1,70 kgs), dynamic 34,57 seconds (SD-1,27 second) and at the position 40-601, static 35,37 kgs (SD=0,79 kg), dynamic 34,43 seconds (SD=1,57 second). Based on the result of the analysis it is concluded that: (1) there is an influence of work position on the fatigue of arm muscles of a computer operator, (2) due to the fact that at the angle range 20401,the maximal shoulder joint abduction caused less fatigue on the arm muscles, so a computer operator should take care of work position to prevent any repeated fatigue.
