| 1 | The major new findings in this study are that in healthy humans (1) renal cortical blood flow decreases (basal versus handgrip, 4.4 +/- 0.1 versus 3.5 +/- 0.1 mL.min-1.g-1; P = .008) and renal cortical vascular resistance increases (basal versus handgrip, 17 +/- 1 versus 26 +/- 2 U; P = .01) in response to static handgrip exercise; (2) central command and/or the mechanoreflex contributes importantly to the early decrease in renal blood flow (basal versus handgrip, 4.2 +/- 0.2 versus 3.5 +/- 0.3 mL.min-1.g-1; P = .04) and to the increase in renal cortical vascular resistance (basal versus handgrip, 20 +/- 1 versus 25 +/- 2 U; P = .04); (3) the muscle metaboreflex contributes to further decreases in renal blood flow (basal versus posthandgrip circulatory arrest, 4.3 +/- 0.1 versus 3.5 +/- 0.2 mL.min-1.g-1; P = .002) and increases in renal cortical vascular resistance (basal versus handgrip, 18 +/- 1 versus 25 +/- 3 U; P = .002); and (4) exogenous adenosine activates the muscle metaboreflex producing reflex renal vasoconstriction and decreased renal blood flow, which may implicate endogenous adenosine generated during ischemic exercise as a potential activator of the muscle metaboreflex during ischemic handgrip exercise. | Adenosine | CD59 molecule (CD59 blood group) | Homo sapiens |
