Popis: 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
