Figure 5. The blood pressure response to muscle contraction at graded intensities.

Figure 5

A, static contractions at submaximal workloads elicited pressor responses that were positively correlated to force development in both WKY and SHR rats (P < 0.001). B, the contraction-induced increase in MAP was significantly larger in SHR than WKY rats beginning at intensity levels corresponding to 34–67% of maximal tension development. For correlation analysis, all data points within a group were used for statistical testing and averaged for presentation only. *P < 0.05 compared to WKY rats.
