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)

The skeleton system of our body plays a vital role throughout our lifetime. It acts as pillar of support for our body’s framework and protects our vital organs. Additionally, bones help in storing minerals like calcium and phosphorous, as well as support the muscles for locomotion. From birth to old age our bones go through series of changes.

By the age of 30, the bone mass density reaches its peak. After which it tends to lose more bone mass than it is deposited. Osteoporosis is a frequently occurring condition developed by people as they grow old. In this condition, bones become weak and fragile. Consequently, it becomes difficult to heal a broken bone after an osteoporotic fracture.

According to statistics, adult population above the age of 50 tends to break their bones easily. Where it is seen, 1 in 2 women and 1 in 4 men fracture their bones due to osteoporosis. Hence, it is important to take care of our bones from young to old age.

There are certain risk factors which may act as a catalyst for accelerating osteoporosis early. Lack of vitamin D and calcium in diet, lack of physical activity, being underweight, smoking and drinking, irregular hormonal levels and intake of certain medications are some common examples of risk factors.

The risk factors increase the vulnerability of osteoporosis as we age. Dr Harish Ghoota, Additional Director-Orthopaedics, Fortis Escorts Hospital, Faridabad shares the following steps to incorporate in your lifestyle to better bone health:

  • Incorporating food and drinks rich in calcium and vitamin D is a good step. For example, low-fat dairy, tofu, soy milk, green leafy vegetables, leguminous pulses, salmon and nuts are good sources for calcium. Exposing one’s body to sunlight for 10-15 minutes twice or thrice a week acts as a good source for vitamin D. Food products like fortified milk and cereals, salmon, tuna, shrimp and oysters are also good sources for vitamin
  •  Indulging in regular exercise for minimum half an hour keeps the muscles and bones strong. Strength building, weight training exercises and dancing are one of the best ways to keep fit and healthy bones
  • Avoid tobacco and alcohol abuse. According to medical advice, women should not consume more than one drink per day and men should not consume more than two drinks per day
  • With increasing age, regular bone density tests and health check-ups with doctors helps prevent excessive bone density loss.

    Taking care of your bones from a young age becomes essential to prevent poor bone health. During childhood and adolescent years, bones rapidly grow. These form crucial years for developing good bone health. Proper balanced diet with increased intake of calcium rich foods and minimum one hour of physical exercise everyday helps to maintain good bone health. Additionally, adults after 30 years of age must integrate healthy lifestyle practices. These activities help to prevent poor bone health after the age of 30:

  • Exercising daily for 30 minutes least
  • Being cautious from falls or accidents
  • Going for regular check-ups
  • Regular bone density tests. Especially, after age of 50 with a fractured bone

  • Additional intake of calcium and vitamin D over the age of 50
  • Regular medication, if prescribed by doctor, for bone density
  • Periodic Dexa scan test for high risk or vulnerable patients. (IANS)
