    The objective evaluation of the muscle strains is very important when analyzing work and itćs consequences - work related and professional diseases and preparing ergonomic solutions in work places. ... The electrical activity of the right dominant upper arm muscles, mainly m.biceps brachii, was determined during isometric and dynamic work by surface electromyography in seven healthymen. Electrical signals were processed by Fast Fourier Transform and expressed as total electrical muscular power (TEMM). TEMM was correlated with mechanical strains defined in two different ways. Torque calculation were usedto evaluate isometric, while rotation impulse was taken as a dynamic measurement of strains. Within person correlations between torque and TEMM ranged from 0.92 to 0.96 (p<-0.01) while the correlation between rotation impulse and TEMM were 0.66 to 0.87 (p<-0.01). As expected isometric and dynamic strengths measurements gave different results. Larger TEMM are by dynamic strengths (analysis of variance by significance p<-0.002). The same method was used in the analysis of the work cycle called Ćcleaning of drop in shaftĆ, which is one of the tasks of the self governing mechanic in the Thermal Power Plant at Šoštanj. From the correlation between mechanical strains and processed electrical signal by standardization it was assumed on muscle strains at professional work from TEMM during work. And physiological standards for them exist. In our case they were not exceeded.
