Is exercise the secret to longevity?

By Medisys on June 15 2016 | Physical Health, Dr. Vivien Brown

According to a large British study, people who take up fitness later in life are more likely to "age successfully" and stay healthy compared with those who remain "couch potatoes".

Olga Kotelko, a resident of West Vancouver, lived until her mid-90s, throwing a javelin and competing in senior’s track and field events. Was her longevity a result of regular physical  activity? Let’s explore what research says about our physical body, exercise and aging.

Why should we start or continue exercise at the age of 65 or older?

The aging process is known to reduce our physical capacity and threaten our independence. Exercise helps slow age related physical change.  According to the CFLRI, or Canadian Fitness and Lifestyle Research Institute, exercise can help:

  • reduce anxiety and depression
  • improve balance and prevent falls
  • reduce pain symptoms
  • create a feeling of well-being
  • improve cognitive function and mood
  • reduce the risk of osteoporosis
  • control hypertension, cholesterol, diabetes and obesity
  • maintain autonomy
  • add years of independent, autonomous living
  • reduce morbidity and prolong life span

 

Dre Vivien Brown explains why exercise is important not only for your cardiovascular health, but also for your brain health

What are the risks?

Clinical trials have shown the universal benefits of exercise, however it does not come without some risks. The most common are musculoskeletal injury and cardiac events. Fortunately, these events can be prevented with proper training techniques and support through a personalised program created by a qualified kinesiologist, exercise medicine specialist or exercise physiologist.

 

Keys to reducing risk and enjoying exercise

The general risk for heart disease and subsequent cardiac events can be reduced with regular, moderate exercise, but be aware that cardiac events can also be triggered with high intensity exercise. It’s important to know how to measure your personal limitations.

 

Bottom line? It’s never too late to start or improve your exercise routine – meet a kinesiologist during a Medisys preventive health assessment and get personalized recommandations.

Knowing how to measure intensity is key in reducing risk and enjoying the benefits of exercise.

Walking is a beneficial form of exercise for all ages, so let’s use it as an example. When walking, ask yourself, “Out of 10, how difficult does this exercise feel?” Moderate intensity will fall between a self-perceived rating of five to seven. Your kinesiologist can teach you how to measure your self-perceived exertion to reduce risk.

 

What is the right amount of exercise for me?

At a minimum, seniors should set a goal of 150 minutes per week of moderate intensity, aerobic exercise and two sessions per week of muscle strengthening activities. Daily stretch and balance practices are also highly recommended.

 

Follow these tips

  • Find an activity you can enjoy easily with some friend as swimming or playing tennis
  • Increase your level activity slowly
  • Walk whenever you can: to walk the dog, to go to the grocery store, every step counts
  • When possible, try to take the stairs instead of the elevator
  • Try to carry your groceries home when they're not too heavy

What types of exercises should you do?

SQUAT TO STAND Using a chair or bench, position your feet hip-width apart with your toes pointing straight ahead. Slowly lower yourself down, bending at the knees until your buttocks touch the chair. Then, press up into a standing position, drawing hips forward. Aim for 2 sets of 10 repetitions.

WALL PUSH UPSStand with your feet hip-width apart and your hands at shoulder height (or just below). Stand with your body weight at a slight angle to wall. Slowly bring your chest to the wall, maintaining a straight spine. Breathe out and bend your elbows. Breathe in and press away until your arms are fully extended.

 

Is it too late to start?

It's never too late to commit time to exercise. Adults who exercise consistently over their lifetime, and continue to exercise four or more times per week between the ages of 70 to 78 improve their survival rate by 10 years. And those between the ages of 70 to 78 who start to exercise and progress to four or more times per week nearly match the 10 year survival rate. Adults between the ages of 85 to 88 also reap the rewards of an improved survival rate.
