Experimental Study on Biomedical Signal Acquisition of Sports Fatigue

Abstract

To explore the biomedical signal acquisition of sports fatigue, the Pclab-UE biomedical signal acquisition and processing system is used to collect and process heart rate variability (HRV) automatically after quiet and fatigue exercise. In the meanwhile, the experimental data are analyzed. The heart rate variability of the subjects is recorded, aiming to provide experimental evidence for the future application of HRV in the diagnosis of exercise fatigue. Moreover, it also provides a noninvasive diagnostic index for exercise fatigue and exercise training practice. The research results showed that, the HRV values in the sub-maximal exercise caused fatigue. The maximal exercise induced fatigue is significantly decreased and there are significant differences. As a result, it is summed up that we can use HRV as a quantitative analysis index for the diagnosis of sports fatigue.
