摘要Fatigability describes the decline in force production (i.e.,performance fatigability) and/or changes in sensations regulating performance (i.e.,perceived fatigability) during whole-body activity and poses a major challenge to those living with spinal cord injuries (SCI).After SCI,the inability to overcome disruptions to metabolic homeostasis due to cardiorespiratory limitations and physical deconditioning may contribute to increased fatigability severity.The increased susceptibility to fatigability may have implications for motor control strategies and motor learning.Locomotor training approaches designed to reduce fatigability and enhance aerobic capacity in combination with motor learning may be advantageous for promoting functional recovery after SCI.Future research is required to advance the understanding of the relationship between fatigability,cardiorespiratory function and motor performance following SCI.
