Purpose of our study was to evaluate chronic physical effort influence' over muscular characteristics, at different categories of players, handball ones and fence players, to analyze and compare the obtained results and to outline specific electromyography patterns, which gathered muscular characteristics for each studied sports. Study lot was composed of 21 male professional sportsmen, 11 fencers and 10 handball players, with a professional experience of at least 8 years, in one of the sports, without significant differences between ages, heights and weights. Was used EMG BIOPAC MP 150 two channels device, with two active electrodes for each channel, the reference one being placed on forearm distal extremity, which was connected to a PC Pentium IV, whose program processed the informations offered by BIOPAC system, to record EMG at professional players, during maximum isometric contractions of fingers flexors from both hands. For an easy evaluation of obtained parameters, these ones were classified in the following categories: of time, of frequency, mixed and for each one of these categories, were calculated other characteristic indexes. For mixed parameters category, the lowest values were at fencers and the highest ones at handball players. EMG patterns were various, specific to the type of physical effort, that characterized each studied sports and proved to be a significant help for sports performance increasing, by assisting trainers to conceive an efficient professional training programs for sportsmen.
