this paper presents the fatigue life behavior of hub using random vibration based on road roughness. the main objectives of this study are to predict the fatigue life and to identify the critical location for evaluating fatigue damage. asphalt road surface profiles obtained in favorable circumstances by topography cameras and in according road classification iso 2631-1estimate road roughness su...

Background: Muscle fatigue is an important issue in neuromuscular rehabilitation. Better control of this phenomenon would result in better prevention of its consequent physiological damages.Objective: To provide a mathematical representation of muscle fatigue as a function of time.Methods: We conducted this study by combining the EMG-based estimation methods of muscle activation with the availa...

Background: Despite the increase in the use of low-level laser therapy (LLLT), there is still a lack of consensus in the literature regarding how often the equipment must be calibrated. Objective: To evaluate the real average power of LLLT devices in the Greater São Paulo area. Methods: For the evaluation, a LaserCheck power meter designed to calibrate continuous equipment was used. The power m...

135 General discussion In the general introduction, it was stated that occupational work often involves prolonged sustained low-force repetitive activities and a number of recent trends may further increase the prevalence of this type of work. Although force levels are relatively low, muscle fatigue or physiological signs of localized muscle fatigue may develop during low-intensity work. Locali...

BACKGROUND Mechanical overload and poor quality of contractile elements related to metabolic abnormalities concur to motor disability of obesity. The independent contribution of these factors to motor dysfunction in obese individuals is scarcely defined. AIM Aim of the study is to test the hypothesis that metabolic factors may independently affect motor function in obesity. METHODS Leg maxi...
