How to age well through exercise

Studies have reported that progressive resistance training and nutrition have been effective in slowing the loss of muscle mass. Here are a few recommendations to slow the rate of muscle loss in one’s middle age.
  • Perform progressive resistance training: Include movements that involve big muscle groups such as hip/knee/ankle/shoulder extensors and flexors. Keep the load low and gradually build volume, performing two to three sets of eight to 10 repetitions with control (technique is key, therefore supervision of a qualified coach will be important).
  • Add progressive balance and coordination exercises: Mindful movements that are commonly seen in yoga, tai chi and pilates can be incorporated. But movements should be progressed gradually based on individual competency and the structure of the joints. Remember, everyone’s virabhadrasana (warrior pose) may not look the same due to the structure of the hip and pelvic joint and/or competency level.
  • Diet: Add enough protein, essential fats such as omega-3 in your diet along with important micronutrients such as calcium and magnesium. Make sure overall energy intake is adequate.
How to age well through exercise
Several factors influence ageing. Physiological conditions (that is, not suffering from major illnesses and the ability to function without depending on others), social and psychological well-being can all play a role in overall quality of life. Over the years, many clinical trials have confirmed that exercise can be very effective in positively influencing the overall quality of life.
However, exercise is one aspect of the overall, bigger movement framework. So instead of having a set mindset regarding exercising, we should rather seek opportunities to move consistently well. Here are a few important movement strategies…
  • Explore different movements: Instead of relying on moving a set way to get your exercise dosage, try and include various movements. For example, some people get so obsessed with long-distance running and walking that they lose the opportunity to explore other movements. Learning new movement skills can help with cognitive brain development and also keep things less monotonous. In addition, there can be less wear and tear on the joints, provided movements are performed well.
  • Quality over quantity: Movements should be gradually progressed, emphasising on quality. Remember, it is better to be consistent rather than going hard for a month and then not doing anything the following month. Further, most injuries happen when we add too much stress too early, as a result the body breaks down. This can negatively impact the overall quality of life.
  • Measurements: Measurements such as calories burnt and steps count keep a track of our daily activities but one should not be obsessed with them. Many people tend to go through guilt trips when they do not exercise for a set duration of time. They do not realise that even if they break the total duration into shorter sessions throughout the day they can still get the same benefit.

Look before you do a treadmill test

senior Indian physician has called for the elimination of stress electrocardiogram treadmill tests from routine health check-up packages, saying they may expose healthy people to unnecessary anxiety, costs and more tests, including invasive coronary angiography.
Prem Pais, professor of internal medicine at the St John’s Research Institute, Bangalore, said treadmill tests, when routinely done during health check-ups, can result in unacceptably high rates of “false positives” — or false signals of coronary artery disease (CAD) in people who actually do not have the disease.
People with false positive results may be advised more expensive tests, such as computerised tomography coronary angiography that exposes them to unnecessary X-rays or percutaneous coronary angiography that exposes them to invasive procedures, Pais said in a report published in the Indian Heart Journal.
Some patients with false positive results may even be prescribed treatment for CAD which, he said, would result in unnecessary expenses and possible side effects of the medications.
“It is not advisable to include TMT (treadmill tests) in routine health check-ups. It is important for cardiologists, physicians and members of the public to take note of potential harms from false positive results,” Pais told The Telegraph.
India has a giant market for preventive health check-up packages, driven by pulls from the private health-care sector and demand from health-conscious individuals. Hospitals often include the treadmill test as part of diagnostic tests to assess the risk for CAD.
RedSeer, a market analysis and consultancy company, estimated in a report released in September this year that the preventive health-care segment market in India was expected to grow to $100 billion by 2022 from $55 billion in 2018.
