ANALYSIS OF CORRELATION BETWEEN THE VARIABLES OF TEMPERATURE, STRENGTH AND CYCLES PER MINUTE TO PERFORM HORIZONTAL REPETITIVE MOVEMENTS OF THE WRIST

The need to protect workers against the causes of occupational diseases and accidents is a no doubt question. Hence the interest to analyze the behavior with variables in temperature in the area of the wrist, strength and cycles per minute, that to perform horizontal repetitive movements of the wrist, which are commonly found in workplaces. Objective: The objective was to correlate the variables of temperature, strength and number of movements per minute when working with horizontal repetitive movement of the right hand wrist area. Delimitation of the problem: It was simulated a working day of 8 hours with 2 operators (man and women) exerting horizontal movements, on the installations of the Faculty of Engineering Ensenada of the Autonomous University of Baja California. Methodology: It was simulated a working day with two operators exerting horizontal movements, and for this making the temperature recorder in the area of the right hand wrist (sensorial thermograph Sköll), the strength of the operator (dynamometer wrist twisting Baseline) and cycles per minute, the three mentioned records were made every ten minutes. Results: The obtained results were: in the operator 1 ,there was a correlation in cycles per minute against temperature and against strength, besides the maximum in: temperature was 35.93°C, strength was 82 kg and cycles per minute was 138 movements and the minimum in: temperature was 28.11°C, strength was 36 kg and cycles per minute was 93 movements; in the operator 2: there was a correlation in cycles per minute, besides the maximum in: temperature was 34.87°C, strength was 63 kg and cycles per minute was 140 movements and the minimum in: temperature was 29.38°C, strength was 32 kg and cycles per minute was 100 movements.
