Aerobic exercise performed in the evening benefits elderly hypertensives more than morning exercise

Evening training was more effective in terms of improving cardiovascular autonomic regulation and lowering blood pressure. This can be partly explained as due to an improvement in baroreflex sensitivity and a reduction of muscle sympathetic nerve activity, which increased in the evening.

Aerobic training is known to regulate blood pressure more effectively when practiced in the evening than in the morning. Now, researchers conducted a study of elderly patients at the University of São Paulo’s School of Physical Education and Sports (EEFE-USP) in Brazil, and they concluded that evening exercise is better for blood pressure regulation thanks to improved cardiovascular control by the autonomic nervous system via a mechanism known as baroreflex sensitivity.

An article on this study, “Evening but not morning aerobic training improves sympathetic activity and baroreflex sensitivity in elderly patients with treated hypertension”, was published in the The Journal of Physiology.

“There are multiple mechanisms to regulate blood pressure, and although morning training was beneficial, only evening training improved short-term control of blood pressure by enhancing baroreflex sensitivity. This is important because baroreflex control has a positive effect on blood pressure regulation, and there aren’t any medications to modulate the mechanism,” Leandro Campos de Brito, first author of the article, said.

In the study, 23 elderly patients diagnosed and treated for hypertension were randomly allocated into two groups: morning training and evening training. Both groups trained for ten weeks on a stationary bicycle at moderate intensity, with three 45-minute sessions per week.

Key cardiovascular parameters were analyzed, such as systolic and diastolic blood pressure, and heart rate after ten minutes’ rest. The data was collected before and at least three days after the volunteers completed the ten weeks of training. 

The researchers also monitored mechanisms pertaining to the autonomic nervous system (which controls breathing, heart rate, blood pressure, digestion, and other involuntary bodily functions), such as muscle sympathetic nerve activity (which regulates peripheral blood flow via contraction and relaxation of blood vessels in muscle tissue) and sympathetic baroreflex sensitivity (assessing control of blood pressure via alterations to muscle sympathetic nerve activity).

In the evening training group, all four parameters analyzed were found to improve: systolic and diastolic blood pressure, sympathetic baroreflex sensitivity, and muscle sympathetic nerve activity. In the morning training group, no improvements were detected in muscle sympathetic nerve activity, systolic blood pressure or sympathetic baroreflex sensitivity.

Evening training was more effective in terms of improving cardiovascular autonomic regulation and lowering blood pressure. This can be partly explained as due to an improvement in baroreflex sensitivity and a reduction of muscle sympathetic nerve activity, which increased in the evening.

“For now, all we know is that baroreflex control is the decisive factor, from the cardiovascular standpoint at least, to make evening training more beneficial than morning training, since it induces the other benefits analyzed. However, much remains to be done in this regard in order to obtain a better understanding of the mechanisms involved,” said Brito.

Baroreflex sensitivity regulates each heartbeat interval and controls autonomic activity throughout the organism.

“It’s a mechanism that involves sensitive fibers and deformations in the walls of arteries in specific places, such as the aortic arch and carotid body. When blood pressure falls, this region warns the brain region that controls the autonomic nervous system, which in turn signals the heart to beat faster and tells the arteries to contract more strongly. If blood pressure rises, it warns the heart to beat more slowly and tells the arteries to contract less. In other words, it modulates arterial pressure beat by beat,” Brito said. 

In previous studies, the EEFE-USP research group showed that evening aerobic training reduced blood pressure more effectively than morning training in hypertensive men (read more at agencia.fapesp.br/34194), and that the more effective response to evening training in terms of blood pressure control was accompanied by a greater reduction in systemic vascular resistance and systolic pressure variability (read more at agencia.fapesp.br/37432).  

“Replication of the results obtained in previous studies and in different groups of hypertensive patients, associated with the use of more precise techniques to evaluate the main outcomes, has strengthened our conclusion that aerobic exercise performed in the evening is more beneficial to the autonomic nervous system in patients with hypertension. This can be especially important for those with resistance to treatment with medication,” Brito ended.

A registered nurse, “Ching” – as many fondly call Rachelle Grace – believes that a holistic approach to health and wellness is what everyone should aim for. She is, therefore, always on the lookout for what could help achieve this. And yes, she shares them openly, believing “knowledge about what works won’t be much use if it’s not known by as many as possible”.

Heart failure patients who do yoga have stronger hearts, can be more active

Patients who did yoga had healthier hearts and were more able to carry out ordinary activities such as walking and climbing stairs than those who only took medications. Patients with heart failure should speak to their doctor before starting yoga and should then receive training from an experienced instructor.

Yoga focused on breathing, meditation, and relaxation is linked with symptom improvement in patients with heart failure.

This is according to research presented at Heart Failure 2024, a scientific congress of the European Society of Cardiology, with the study’s author, Dr. Ajit Singh of the Indian Council of Medical Research (ICMR), Manipal Academy of Higher Education, India, emphasizing that “patients who practiced yoga on top of taking their medications felt better, were able to do more, and had stronger hearts than those who only took drugs for their heart failure. The findings suggest that yoga can be a beneficial complementary therapy in patients with heart failure.”

Heart failure affects vast numbers of people – more than 64 million globally – and can have devastating impacts on quality of life, with patients feeling tired and breathless, and being unable to participate in their usual activities. While previous studies have shown the short-term benefits of yoga in patients with heart failure.

This study enrolled patients aged 30 to 70 years with heart failure from the cardiology outpatient department of Kasturba Hospital in Manipal, India. All participants had undergone a cardiac procedure within the past six months to one year and were taking guideline-recommended heart failure medications. Patients with severe symptoms were excluded.

The study included 85 patients. The average age was 49 years and 70 (82%) were men. In a non-randomised fashion, 40 patients were assigned to the yoga group and 45 patients were allocated to the control group. All participants continued taking guideline-recommended heart failure medications throughout the study.

Experienced faculty in the hospital’s Department of Yoga demonstrated pranayama (yogic breathwork), meditation, and relaxation techniques to patients in the yoga group. Participants were supervised for one week and then advised to continue self-administered yoga at home once a week for 50 minutes. Patients spoke to an instructor after each home session to check progress.

At baseline, six months, and one year, the researchers assessed heart structure and function in the yoga and control groups using echocardiography. The measurements included the ability of the heart to pump blood (left ventricular ejection fraction), and assessment of right ventricular function. The researchers also examined blood pressure, heart rate, body weight, and body mass index. Symptom burden and the ability to do ordinary activities such as walking and climbing stairs were assessed using the New York Heart Association classification system.

Compared to the control group, the yoga group demonstrated significantly greater improvements in all measurements at six months and one year relative to baseline.

Dr. Singh said: “Patients who did yoga had healthier hearts and were more able to carry out ordinary activities such as walking and climbing stairs than those who only took medications. Patients with heart failure should speak to their doctor before starting yoga and should then receive training from an experienced instructor. Prescribed medications should be continued as before. Yoga may be unsuitable for heart failure patients with severe symptoms, who were excluded from our study.”

Running under a four-minute mile could be the key to a long and healthy life

Elite runners live on average almost five years longer than the general population.

The more – and faster – you run, the better for your health?

A study released to mark the 70th anniversary of Sir Roger Bannister’s sub-four-minute mile record revealed the first 200 runners to follow in his footsteps also share another remarkable trait. More particularly: the study from investigators in Australia and Canada found the 200 elite runners live on average almost five years longer than the general population.

The study, published in the British Journal of Sports Medicine, demonstrate the vital importance of aerobic fitness.

According to Professor Mark Haykowsky: “Breaking the four-minute mile was an extraordinary achievement 70 years ago and revealed just what the human body can achieve. It set off a wave of runners following in Sir Roger’s mighty footsteps.

“Remarkably we found that like Sir Roger, who lived to the ripe old age of 88, most of the first runners also lived well into their 70s, 80s and a majority are alive and healthy today.”

The multi-national team tracked down the health records of the first 200 people to complete the sub-four-minute mile. This included runners from the UK, Australia, France, New Zealand, and the United States who were born between 1928 to 1955. All 200 runners are men, and a majority were still alive.

Professor Andre La Gerche, a sports cardiologist who heads the HEART Laboratory supported by St Vincent’s Institute of Medical Research and the Victor Chang Cardiac Research Institute in Australia, says: “Our study set out to see how exercise affected elite athletes over the long term. We know that elite athletes have bigger hearts due to their sustained aerobic output and there was some belief that this could affect their health and longevity, but we found the opposite.

“Five years of extra life compared to average is very significant, especially when we found that many of these runners not only enjoyed long lives but were also healthy too.

“Not everyone needs to be able to run a sub-four-minute mile to enjoy good health long into old age, but they need to exercise regularly and push themselves aerobically.”

The world record for the mile now stands at 3.43 and is held by Hicham El Guerrouj of Morocco. Ollie Hoare is the fastest Australian (3.47.48) and Kevin Sullivan holds the Canadian record (3.50.26) both of which were set at the Bislett Games in Oslo, Norway. No female runner has yet broken the four-minute barrier. The women’s world record is currently at 4:07.64, set by Faith Kipyegon of Kenya in 2023.
