Abstract 19648: Post-exercise Blood Pressure Following Different Resistance Training Methods in Treated Older Hypertensive Women

Introduction: The purpose of this study was to examine post-exercise blood pressure following different resistance training methods in treated older hypertensive women. Methods: The sample consisted of 14 female volunteers with controlled hypertension (age 69.86 ± 5.67 years, weight 59.31 ± 9.77 kg, height 1.52 ± 0.06 m, BMI 25.76 ± 4.44 kg/m2) who attended six Laboratory visits. The first four visits aimed at collecting anthropometric data, familiarization and determining the training load. In the fifth and sixth visits, volunteers performed a traditional resistance exercise method (TRE) and a circuit resistance exercise method (CRE), in a randomized order. The sessions were separated by at least 48 hours, involved the following exercises: leg press, seated row, knee extension, bench press, knee flexion, lateral raise with dumbbells and seated calf raises. In TRE, the exercises were performed in three sets of 12 repetitions with an interval of 60 seconds between sets and exercises. In the CRE, the exercises were performed in circuit, with 3 rounds of 12 repetitions with 30 seconds rest between exercises and 60 seconds between rounds. The intensity was adjusted corresponding to the level 4 of the scale of perceived exertion to resistance exercise. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at rest, 15, 30, 45 and 60 minutes after the exercise sessions. Mean blood pressure (MBP) was calculated. Data normality was verified with the Shapiro-Wilk test. ANOVA for repeated measures (time X method) was used for data analysis. Significance was set at p <0.05. Results: Although mean SBP values were reduced following exercise, no significant effects of time, methods or time X method interaction were noted in SBP, DBP and MBP. Conclusions: Both resistance training methods, on intensity corresponding to the level 4 of perceived exertion scale, were not able to significantly alter the blood pressure of treated older hypertensive women
