Comfort assessment in the use of shotgun for skeet shooting: an EMG based approach

In the last decades the improvements of sportive performance are due to the consistent innovation in equipment, clothing and training. Hence for what regards the equipment, comfort is becoming everyday more interesting as it strongly influences the performance and the risks of injuries. Is therefore, proposed in this research a methodology for an assessment of the comfort using frequency domain indexes, that are fatigue dependent, extrapolated from the surface electromyographic signal. The use of mean and median frequency of the surface electromyography were found to be useful indicators of fatigue in dynamic condition hence fatigue can be used as one of the variables concurring in the assessment of comfort. The methodology proposed could be used for both improvement of the performances of the athlete and either for quantifying the comfort in the interaction between the athlete and his sport equipment.
