Active clinical trials for "Post-Exercise Hypotension"

The goal of this study is to learn about how blood vessel dilation after exercise effects pulse wave reflection and influences the function of the heart in healthy young adults. The main question it aims to answer is: Are post-exercise decreases in reflected pulse waves due to a decrease in the stiffness of large arteries in the leg or an increase in leg blood flow? Participants will exercise on a stationary bicycle at a moderate intensity for 1 hour during two laboratory visits. Participants will take oral antihistamines to block post-exercise dilation at one visit, and they will take placebo pills at the other visit. At both visits, leg blood flow, pulse wave velocity, and heart function will be measured before exercise and for 120-minutes after exercise.

This study is investigating the role of histamine in generating adaptation to exercise

This study examines the effect of obesity and gender on postexercise hypotension with three different randomized exercise protocols or varying intensity. Subjects will be separated into obese and non-obese groups and then further by gender. From there, they will be put through a control, continuous exercise bout, and aerobic interval bout of exercise in a randomized order over three visits. Post exercise blood pressure, as well as other non-invasive cardiac measures will be taken over a 4 hour period.

This is a randomized controlled trial. The present study involves an acute and chronic intervention, which is a water-based exercise (one session: to acute intervention; 12-weeks of aquatic exercise program: to chronic intervention). The sample will be composed by elderly enrolled in university extension program titled "Hidroginastica na Terceira Idade" (Hydrogymnastics in aging). It will be evaluated the effects of water-based exercise on hemodynamics, self-reported sleep quality, depressive symptoms, quality of life, body composition, level of physical activity and functional capacity. The investigators hypothesized that an acute water-based exercise under different intensities promotes hemodynamics changes in elderly. In addition, the investigators hypothesized that 12-weeks of aquatic exercise may lead improvements in self-reported sleep quality, depressive symptoms, quality of life, body composition, level of physical activity and functional capacity in elderly.

Sedentary (n=24) adults ≥18 yr with elevated BP to established hypertension were enrolled into this randomized clinical trial entitled, 'Blood Pressure UtiLizing Self-Monitoring after Exercise study or PULSE'. Participants were randomly assigned to either an exercise only (EXERCISE; n=12) or exercise plus BP self-monitoring (EXERCISE+PEH) (n=12) group. All participants participated in a 12 wk supervised moderate intensity aerobic exercise training program 40 min/d for 3 d/wk. In addition, they were encouraged to exercise at home ≥30 min/d for 1-2 d/wk. All participants self-monitored exercise with a traditional calendar recording method and heart rate (HR) monitor. In addition to traditional exercise self-monitoring (EXERCISE), individuals in the EXERCISE+PEH group were given a home BP monitor to assess home BP twice daily (in the morning upon awakening and in the evening) and prior to and after voluntary home exercise sessions. Resting BP, peak oxygen consumption (VO2peak), physical activity, dietary and salt intake, and antihypertensive medication adherence were measured before and after the 12 wk supervised exercise training program. In addition, integrated social-cognitive predictors of exercise that included questionnaires on exercise self-efficacy, barriers self-efficacy, outcome expectations for exercise, exercise intention, and affective responses to exercise were measured before and after the 12 wk supervised exercise training program. Four weeks following the completion of exercise training, self-reported exercise levels were assessed during a telephone interview in both groups. Among EXERCISE+PEH only, self-monitoring of BP was also self-reported during this telephone interview.

The aim of this study was to determine the energy demand and the potential to promote reduce blood pressure of an active video game (AVG). Fourteen hypertensive (56.4 ± 7.5 years) held a session AVG and traditional sedentary video game sessions (SVG) and walk (WAL), as negative and positive controls, in order determined randomly. During the sessions, they were observed oxygen consumption and energy expenditure (EE). Blood pressure (BP) and cardiac autonomic modulation (CAM) were measured at rest and every 15 minutes of a 60 minute period of recovery activities. It was also applied a rating scale of pleasure (enjoyment scale).

The purpose of this study is to compare the effects of two exercise protocols on post-exercise blood pressure versus a control group in elderly hypertensive men. Participants are allocated to all groups: control group and two experimental exercise protocols, in a random order. In the control group, participants remain resting sitting, and, in the exercise protocols, participants practice exercise bouts of aerobic exercise or a combination of resistance and aerobic exercises. In order to standardize baseline conditions, before the sessions subjects remain sitting quietly for 20 minutes. After each exercise protocol, participants have 60 minutes for recovery and, simultaneously, they have BP measured every 5 minutes. After the exercise sessions or control, an equipment for 24 hours ambulatory BP monitoring is installed in every participant.

A quasi-experimental study developed in sedentary morbidly obese men and women (age 43.6±11.3 y; body mass index [BMI] ≥40 kg/m2) were assigned to a CT group of ET plus RT (ET+RT; n=19; BMI 47.8±16.7) or RT plus ET order group (RT+ET; n=17; BMI 43.0±8.0). Subjects of both groups received eight exercise sessions over four weeks. Systolic (SBP), diastolic (DBP), mean arterial pressure [MAP], heart rate at rest [HR], and pulse pressure [PP] measurements before and after 10 minutes postexercise. Secondary outcomes were other anthropometric, body composition, metabolic, and physical condition parameters. Using the ∆SBP reduction, and quartile categorization (Q) in 'high' (Rs: quartile 4), 'moderate' (MRs: quartile 3), 'low' (LRs: quartile 2), and 'nonresponders' (NRs: quartile 1) were reported.

Hypertension is the most prevalent cardiovascular disease risk factor among individuals 60 years of age and older. Hypertension can be prevented and modified with lifestyle interventions that include regular exercise. Water exercise is widely recommended for older adults for a variety of health benefits, but few studies have assessed the immediate ambulatory blood pressure (BP) response to water exercise, a response termed postexercise hypotension (PEH). We will assess PEH after a session of water aerobics in physically active, older women with hypertension. Twenty-four women will be randomly assign to participate in a 45 min session of moderate intensity, water aerobics (WATER) and a 45 min land control session (CONTROL). All experimental sessions will start at 9 am sharply with 7 days between them. Subjects will left the experiments wearing an ambulatory BP monitor for the next 21 hr.

This study evaluates the volume of optimal resistance exercise to generate postexercise hypotension after performing a single exercise in hypertensive elderly subjects. 20 subjects will perform 1 control session and 3 resistance training sessions with different volume: 3, 6 and 9 sets
