Compared to the LD-dark, HR significantly decreased in LL3 and LL4 (both p < 0.001), with a decreasing trend (β = –14.345, p < 0.001, R 2 = 0.736).
Compared to the LD-dark, HR significantly decreased in LL3 and LL4 (both p < 0.001), with a decreasing trend (β = –14.345, p < 0.001, R 2 = 0.736).
Amplitude showed a marginal decline ( p = 0.075), while the F-value decreased with borderline significance ( p = 0.058).
BRS was also considerably affected throughout the experiment (Friedman test, p = 0.017), showing a clear trend of increasing sensitivity.
