Measurement and validation of exercise induced fatigue through inertial motion analysis

Journal Article


Abstract


  • Exercise-induced fatigue evolves from the initiation of physical work. Nonetheless, the

    development of an objective method for detecting fatigue based on variation in ambulatory

    motion parameters measured during exercise is yet to be explored. In this study, the

    ambulatory motion parameters consisting of kinematic parameters of 23 body segments

    in addition to muscle tissue oxygen saturation (SmO2), heart rate, and vertical work of

    eight healthy male subjects during stair climbing tests (SCT) were measured before and

    after a fatigue protocol utilizing Wingate cycling test. The impacts of fatigue on ambulatory

    motion and postural behaviors were analyzed using an unsupervised machine learning

    method classifying angular joint motions. The average of total distance traveled by

    subjects and the overall body postural behavior showed about 25% decline and 90% variation

    after fatigue protocol, respectively. Also, higher relative desaturation in SCT1

    64.0 (1.1) compared SCT2 54.8 (1.1) was measured. Measurements of differences in

    motion postural states and metabolic indexes after exercises-induced fatigue proved a

    strong correlation which validates the advantages of inertial motion analysis method for

    fatigue assessment.
