Abstract

Prolonged standing is an occupational hazard that may evoke many cardiovascular problems. This study investigates the effects of anti-fatigue mats on hemoglobin levels—related to blood pooling—in the lower extremities during prolonged standing. Fifteen subjects (6 M, 9 F; Age = 26 ± 3 years; BMI = 23.2 ± 2.5 kg/m2) stood for one hour on a hard floor and anti-fatigue mat. Oxygenated (HbO), deoxygenated (HbR), and total (HbT) hemoglobin levels were measured for the soleus muscle using near infrared spectroscopy. A mixed-effects model was performed indicating that time, flooring, and their interaction effect were significantly associated with levels of HbO (time, p<0.0001; floor, p=0.0056; interaction, p=0.0033), HbR (time, p<0.0001), and HbT (time, p<0.0001; floor, p=0.0060; interaction, p=0.0062). Results indicate that hemoglobin levels change with time, and flooring has an effect. Blood pooling seems to be the mechanism. Anti-fatigue mats may have a positive effect on cardiovascular outcomes.
