Study on the nonfatigue and fatigue states of orchard workers based on electrocardiogram signal analysis.

However, as for female orchard workers, all 8 HRV parameters showed significant changes (P < 0.05), only meanHR showed an increasing trend, and the remaining time-domain parameters RR SDNN RMSSD, SDSD, PNN50, PNN20, CV showed significant decreases (P < 0.05).

First, among male orchard workers, only HFpercent showed a significant decrease, while VLFpercent and LFpercent showed a trend of change but did not produce a significant difference.

In frequency domain, one of the relative power parameters LF percent (increased 17.82%) was larger than the nonfatigue state, and the other two parameters (VLF percent decreased 5.41% and HF percent decreased 17.82%) showed a decreasing trend.
