Exercise Your Legs For Healthy Brain

Further, they found that restricting exercise lowered the amount of oxygen in the body, which created an anaerobic environment and alters metabolism

Exercising your legs is necessary for a healthy brain and nervous system, said a new study that showed that neurological health depends on signals sent by leg muscles to the brain and vice versa.

The results gave doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited.

Reducing exercise makes it difficult for the body to produce new nerve cells — some of the very building blocks that allows one to adapt to stress and challenges in life.

“Our study supports the notion that people who are unable to do load-bearing exercises — such as patients who are bed-ridden, or even astronauts on extended travel — not only lose muscle mass, but their body chemistry is altered at the cellular level and even their nervous system is adversely impacted,” said Raffaella Adami from the University of Milan, in Italy.

During the study, the researchers restricted mice from using their hind legs, but not their front legs for a period of 28 days. They continued to eat and groom normally and did not exhibit stress.

The findings, published in the journal Frontiers in Neuroscience, showed that limiting their leg activity decreased the number of neural stem cells by 70 per cent compared to a controlled group of mice, which were allowed to use their legs.

Further, they found that restricting exercise lowered the amount of oxygen in the body, which created an anaerobic environment and alters metabolism.

This research demonstrates the critical role of movement and has a range of potential implications. “It is no accident that we are meant to be active: to walk, run, crouch to sit, and use our leg muscles to lift things,” Adami said.

“Neurological health is not a one-way street with the brain telling the muscles “lift, walk, and so on”, Adami said. (IANS)

Exercise More for Better Fitness After Retirement: Study

While retirement can free up time, deteriorating health and wellbeing often become a new barrier. That is why it is so important to maintain fitness in the lead up to retirement

Middle-aged people over 55 years of age in particular should be doing more to keep fit as they approach retirement age because of the physical, mental and social benefits of being active, says a study.

“Adults are spending more years of their life working than ever before. Retiring is a life-changing event which provides all sorts of opportunities – but it coincides with declining physical activity, health and wellbeing,” said the study’s lead author Charlotte Salter from the University of East Anglia in England.

“From the age of around 55, people begin thinking about retirement and making plans for their future,” Salter said.

For the study, researchers worked to gather insight about the relationship between retirement and physical activity.

More than 1,000 over-55s took part in an online ‘Physical Activity and Retirement Transitions’ survey about their physical activity levels and expectations and experiences of retirement.

The research team also held focus groups and interviews with people at retirement age about staying physically active.

“In order to enjoy a fit and healthy retirement, a really key thing is that people need to maintain their physical fitness through their fifties and beyond.

“But we found that there are many barriers to this – from poor health, lack of motivation and the cost and availability of sports, activities and fitness classes, to not having enough time – due to work or in many cases because of caring responsibilities,” Salter added.

The report showed how employers and healthcare providers could do more to promote physical fitness to people over 55. And that sports centres and community fitness projects could also play more of a part in encouraging healthy ageing.

While retirement can free up time, deteriorating health and wellbeing often become a new barrier. That is why it is so important to maintain fitness in the lead up to retirement.

“There is no one-size-fits all approach. But we found that activity that is combined with socialising, or other purposeful actions such as dog walking, gardening, housework, childcare or volunteering, were all good ways for over-55s to remain active,” she added. (IANS)
