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)

Having A Muscular Body Can Increase Your Longevity

"Rising from a chair in old age and kicking a ball depend more on muscle power than muscle strength, yet most weight-bearing exercise focuses on the latter"

The highest value achieved after two-three attempts with increasing loads was considered the maximal muscle power and expressed relative to body weight. Values were divided into quartiles for survival analysis and analysed separately by sex. Pixabay

Want to increase your longevity? If yes, then speed up your weight-lifting routine as a new study suggests muscle power might be key to long life.

The study, presented at the EuroPrevent 2019 in Lisbon, indicates that power depends on the ability to generate force and velocity and to coordinate movement.

“We now show that power is strongly related to all-cause mortality. But the good news is you only need to be above the median for your sex to have the best survival, with no further benefit in becoming even more powerful,” said Araújo. Pixabay

“Rising from a chair in old age and kicking a ball depend more on muscle power than muscle strength, yet most weight-bearing exercise focuses on the latter,” said study author Claudio Gil Araújo, Professor at Exercise Medicine Clinic — CLINIMEX in Rio de Janeiro, Brazil.

“Our study shows that people with more muscle power tend to live longer,” Araújo said.

For the study, the team enrolled 3,878 non-athletes, aged 41-85 years, who underwent a maximal muscle power test using the upright row exercise between 2001 and 2016. The average age of participants was 59 years, five per cent were over 80 and 68 per cent men.

The highest value achieved after two-three attempts with increasing loads was considered the maximal muscle power and expressed relative to body weight. Values were divided into quartiles for survival analysis and analysed separately by sex.

During a median 6.5-year follow-up, 247 men (10 per cent) and 75 women (6 per cent) died, according to the study.

Muscle power start decreasing after 40 years of age.

“We now show that power is strongly related to all-cause mortality. But the good news is you only need to be above the median for your sex to have the best survival, with no further benefit in becoming even more powerful,” said Araújo.

The researchers suggest multiple exercises for the upper and lower body, weight with the load to achieve the maximal power (not so easy to lift and not so heavy that you can barely lift it) may increase muscle power. (IANS)
