Figure 4.

This figure offers clear evidence that blood pressure can vary dramatically during weight lifting and MacDougall and colleagues (1985) have shown pressures can rise nearly 4 times above resting levels during leg press exercise in humans (MacDougall et al, 1985). These data suggest blood pressure is not as rigidly regulated as one might have thought and raises the question: “What is a pathological level of blood pressure?” Figure adapted from MacDougall et al, 1985.
