We tested blood pressure responses to the Bruce treadmill protocol PRE and POST 12‐wks of matched volume training on a land treadmill (LTM, n= 9♂,13♀, age=43±3 yrs, weight=88.1±3.6 kg) or aquatic treadmill (ATM, n=18♂, 17♀, age=45±2 yrs, weight=90.6±3.0 kg). Systolic (SBP), diastolic (DBP), pulse pressure (PP) and mean arterial pressure (MAP) were analyzed using a 2 (ATM or LTM) x 2 (PRE & POST) ANOVA repeated for the training time at rest, 3 stages of the exercise protocol, and 1 and 5 minutes of recovery; Tukeyˈs post hoc tests were used as follow‐up for significant interactions, α=0.05. VO 2max increased significantly 11–15% with training in both groups. Significant training changes for MAP shown in Table (mmHg, mean±SE); SBP and PP paralleled these results. Significance remained after covarying for BMI, %body fat, and age. Data suggest ATM may provide superior benefits over LTM for promoting reductions in exercise blood pressure.
