• Description:
  Obesity has been linked to altered gait kinematics and kinetics. For example, individuals who are obese walk with less hip and knee flexion and more ankle plantar flexion during stance. They also exhibit higher hip and knee extensor torques, and higher ankle plantar flexor torque. Increased joint loading with obesity may increase the risk of musculoskeletal pathology. Altered lower extremity strength may explain the differences in gait kinematics and kinetics between obese and healthy-weight individuals. To better understand the importance of lower extremity strength during gait, earlier work investigated relative effort, or joint torques expressed as a percentage of maximum available joint torque. Higher relative effort among obese individuals may help explain their altered gait. To better understand the obesity-related changes in joint load during gait, and to assess the importance of muscle strength, the purpose of this study was to investigate whether and to what extent lower extremity joint torques and relative effort during gait differ with obesity.
