Abstract:

Diploma thesis describes use of a harvester simulators and operator sitting position during a training by using an orthopedic aid call backrest Authoterapia and without that. The paper describes the possibility of a use and its benefits and possibilities of various kinds of simulators as is needed not only in forestry. Part of this work is devoted how to measure an activity of muscles of the trapezoid, hearth rate, blood pressure respiration, temperature and evaluation of their activities on a harvester simulator of John Deere. This thesis is focused on evaluation and comparison between trapezoids muscles activity during exercise and relax time and comparing trapezoids muscles activity with using of orthopedic aid and without used of it. For this research has been used more than 10 million data. Those data were collected with a unique equipment and technique call Biofeedback and transform and evaluated by program Biofeedback X-pert2000 and after that, further elaborated in the program Statisctica. In this research was demonstrated that there is a clear distinction between exercises and relax of trapezoids muscles and some difference of other measured parameters, out of blood volume pressure. But a more significant difference has been demonstrated using backrest Authoterapia. This add-on has been shown to affect operator work and performance. Within the focus on trapezoidal muscles, it has been shown that in some cases it may affect the operator, but provided that the operator has followed the procedure to set up the orthopedic backrest. More significant finding was that the orthopedic device had an impact on 11 of 14 respondents to abdominal breathing. Which can positively affect operator efficiency and vitality.
