Figure 1 Calculated pulmonary artery systolic pressure response to exercise at each stage for athletes versus nonathletes. Mean value and 95% confidence intervals are given. Pulmonary artery systolic pressure was calculated using an assumed RA pressure of 5 mm Hg. Pulmonary artery systolic pressure was higher in athletes than in normals at each stage (p < 0.0001). WP = warm-up period.
