Influence of exercise training on resting blood pressures of Dahl rats.

摘要: To determine whether female Dahl salt-sensitive (SS) hypertensive rats would adapt to chronic treadmill exercise by exhibiting lower resting systolic blood pressures (RSBP), a 12-wk training program was undertaken. Female salt-resistant (SR) were also trained for the same time period similar intensity [40–70% maximal O2 consumption (VO2max)] and duration (55 min). Postexperimental run times VO2max values [SR: nontrained (NT) 87 +/- 1, (T) 97 2; SS: NT 82 2, T 92 3 ml.min-1 X min-1 kg-1] indicated that prescribed had produced state. However, caused no group differences between SR or SS their controls in measurements associated with sodium chloride intake, fluid consumption, urine production, 24-h excretion, plasma volumes, insulin, volumes.
