The Acute Effects of Mat Pilates on Hemodynamic and Salivary Nitrite Responses After Exercise in Postmenopausal Women

摘要

The aim of this study was to compare the hemodynamic and salivary responses after mat Pilates, aerobics, resistance exercises, and control. A total of 16 normotensive postmenopausal women performed: Pilates, 10 floor exercises; aerobics, 35 min on a treadmill (60-70% of heart rate reserve); resistance exercises, 60% of one-repetition maximum; and control, no physical exercise. Blood pressure and heart rate variability were evaluated at rest and 60 min after the intervention. Saliva samples were collected at rest, immediately after, and 30 and 60 min after exercise for analysis of nitrite concentration and total proteins. Systolic blood pressure, diastolic blood pressure, and mean blood pressure area under the curve were lower (p < .05) after both aerobic and resistance exercises sessions but not after the Pilates session when compared with the control session. Nitrite concentrations in saliva were higher 60 min after the end of all exercise sessions. Heart rate variability was higher after the resistance exercise. Aerobic and resistance exercises were capable of decreasing arterial blood pressure after acute exercise.
