CBRS, cardiac baroreflex sensitivity, which was calculated via sequence technique with the data during the Oxford procedure; MBRS, sensitivity of baroreflex control of muscle sympathetic nerve activity (MSNA); MBRS BI, area, total, the sensitivity of baroreflex control of MSNA burst incidence, burst area, and total activity, respectively; RMHE, repeated moderate heat exposure; sequence number, number of detected sequences for CBRS calculation. P: P value of one-way repeated-measures ANOVA. Subject number: n = 7 for Pre-RMHE and Post-RMHE, n = 6 for Post-1wk.
