The investigation of resting-state functional connectivity in male sprinters and endurance runners brains based on fNIRS.

Comparative analyses of functional connectivity strength within the four regions of interest (ROIs) and among the six ROI pairs in the two athlete groups demonstrated highly significant differences in correlation coefficients for PFC-L ( P = 0.003, Hedges’ g = 1.48, 95% CI[0.74, 2.22]), PFC-R ( P = 0.003, Hedges’ g = 1.49, 95% CI[0.75, 2.23]), M1-R ( P = 0.003, Hedges’ g=−1.34, 95% CI[−2.07, −0.61]), PFC-L-PFC-R ( P = 0.004, Hedges’ g = 1.50, 95% CI[0.76, 2.24]), and M1-R-M1-L ( P = 0.001, Hedges’ g=−1.77, 95% CI[−2.26, −0.98]).
