Abstract:
:The aim of this study was to assess the changes in the postural control (PC) during quiet stance among elderly men with fatigue induced by moderate exercise, and to assess the relationships between changes in PC and somatic indices (body mass index (BMI), waist to hip ratio (WHR)), load during exercise, and post-exercise blood lactate (BL) concentration. The study involved 17 elderly men (68.4±2.9 years of age, ranging between 65 and 74 years). Mean velocity of the center of pressure (COP) displacements was measured using a force plate both before and after fatigue induced by a cycle ergometer exercise. Following physical exercise, the mean velocity of the COP and its components, both in the sagittal and frontal plane, increased significantly. It was found that increasing BMI was associated with increasing exercise-induced changes in the mean velocity of the frontal plane. Additionally, BL level was positively correlated with changes in the mean velocity of the sagittal plane. Higher post-exercise values of the mean velocity of the COP may suggest a temporary increase in the risk of falls. Therefore, it seems advisable to caution the elderly men in regards to the increased risk of falling following exercise. Analysis showed that the changes in the PC as indicated by the increase in the COP displacements velocity may be related to the level of fatigue (as indicated by BL). Moreover, elderly men possessing a higher BMI may exhibit a tendency toward the greater increase in the postural sway after exercise-induced fatigue.
