The effect of the standing angle on reducing fatigue among prolonged standing workers

BACKGROUND: Many occupations require workers to stand for prolonged periods, which can cause discomfort, pain and even injures. Some supermarkets in life provide a foot pad checkout staff let them on it at work, thereby reducing standing fatigue caused by long time. The inclined platform is the same as mentioned above. That is, stepped relieved certain extent. OBJECTIVE: study aims analyze how angle affects among tries find an with specific reduce fatigue. METHODS: This experiment studied of platforms different angles workers, eight participants were selected participate test. plantar pressures sEMG (Surface Electromyography) used collect physiological information change lower limb waist. visual analogue scale was subjective method measure psychological RESULTS AND CONCLUSION: highlights relationship between inclination has effects under time conditions. When 0°, 5° 10°, iEMG (Integrated values gastrointestinal muscle not significantly until third sampling point (40 minutes). After that self-regulation muscles better when effect alleviating knowledge crucial design working fitting needs workers.
