Note. ^adf = 1, 22; ^bdf = 4, 88; ^cdf = 1, 21; ^ddf = 4, 84.
Period(s) separated by comma and printed both sides of inequality sign are not significantly different at p < .05.
FE = fish-eating, Cont = control.
BS = baseline, MA = mental arithmetic, R1 = 1^st recovery, R2 = 2^nd recovery, and R3 = 3^rd recovery.
SBP = systolic blood pressure, MBP = mean blood pressure, DBP = diastolic blood pressure, CO = cardiac output, HR = heart rate, SV = stroke volume, TPR = total peripheral resistance, PEP = pre-ejection period, NPV = normalized pulse volume, BRS = baroreflex sensitivity, PWV = pulse wave velocity, and CFVI = cardio-finger vascular index.
