This Bone-Healthy Activity Can Reduce Your Risk Of Severe COVID-19 Symptoms - Save Our Bones

A new study has revealed a clear relationship between physical activity levels and health outcomes of COVID-19 infection. As Savers know, regular exercise has numerous health benefits. We can now add a new item to that list: reduced risk of hospitalization or death due to a COVID-19 infection.

We'll take a look at the details of this study, and learn just how much exercise helped participants to withstand the assault of this dangerous virus.

About The Study

The British Journal of Sports Medicine published a study this past April on physical activity and severe COVID-19 outcomes. The study included 48,440 adult participants who had been diagnosed with COVID-19.

The participants were categorized into three groups based on how many minutes of moderate to vigorous activity they performed each week: 0-10 minutes, 11-149 minutes, or 150 or more minutes. Their physical activity (PA) levels were based on exercise vital sign measurement questions asked by health care professionals. To take a patient's exercise vital sign a doctor simply asks about their physical activity levels, to see if they're exercising enough to maintain good health.

The researchers then compared each participant's health outcomes to the PA level category they fell into. The outcomes considered were hospitalization, admission to the ICU, and death due to COVID-19. This allowed them to calculate how physical activity levels may affect the risk of experiencing those outcomes.1

Synopsis

A study of 48,440 adults diagnosed with COVID-19 compared each participant's physical activity (PA) level to their health outcomes. This allowed researchers to identify associations between physical activity levels and hospitalization, admission to the ICU, and death.

Exercise Reduced The Severity Of COVID-19 Infections

Participants who got the least exercise were significantly more likely to require hospitalization, to be admitted to the ICU, or to die from COVID-19 than participants in either of the groups that engaged in more than 10 minutes of exercise per week.1

People who were exercising at least the recommended 150 minutes a week were the least likely to experience any of the negative outcomes, regardless of other contributing factors (with the exception of age and organ transplant.)1

Compared to the study participants who did the recommended amount of PA, those who did little to no exercise were more than twice as likely to be hospitalized, 73 percent more likely to be admitted to the ICU, and two and half times as likely to die.1

The inactive group was also more likely to experience those three outcomes than people who did a moderate amount of exercise. Their risk was greater by 20 percent (hospitalization), 10 percent (ICU), and 32 percent (death).1

That demonstrates how the benefits of exercise prove to be scalable. People who exercised less than the recommended amount were not as susceptible as those who exercised a little or nothing at all. However, they were still at greater risk than those who got at least 150 minutes of exercise per week.1

The Remarkable Benefits Of Exercise

Here is the researchers’ conclusion:

“Consistently meeting physical activity guidelines was strongly associated with a reduced risk for severe COVID-19 outcomes among infected adults. We recommend efforts to promote physical activity be prioritised by public health agencies and incorporated into routine medical care.”1

Even though this study didn't observe the mechanism behind the association between exercise and better health outcomes for people infected with COVID-19, the researchers are confident that exercise is what caused the improved outcomes.

Part of that confidence stems from the researchers' methodology. They analyzed the data to account for the influence of other factors that might have been impacting the participants' health outcomes. The results were still the same. Except for age and organ transplant, other factors didn't change the relationship between exercise and improved health outcomes.

The other reason we can be confident that exercise is the source of the benefit is because of the extensive existing research that has shown how exercise boosts our body's immune function.

For example, researchers cite a previous study that recommended exercise as a therapeutic prescription for 26 different chronic diseases ranging from depression to musculoskeletal conditions, including osteoporosis.2

In fact, the benefits of exercise that reduce the severity of a COVID-19 infection are also benefits that help support our bones. One of the effects of PA cited by the study is reduced systemic inflammation.3 That inflammation contributes to lung damage caused by COVID-19. The same systemic inflammation has also been linked to bone loss.4

And, as Savers know, weight-bearing exercise also stimulates new bone growth, making it doubly important for building and maintaining strong and healthy bones.

Synopsis

The study authors recommend PA to reduce the risk of severe COVID-19 outcomes. The benefits that make exercise effective at reducing the severity of COVID-19 infections also make exercise effective for improving bone health. Additionally, weight-bearing exercise stimulates new bone growth.

What This Means To You

No matter what other precautions you’re taking to reduce the risk of contracting COVID-19, exercise should be part of your prevention plan. This data demonstrates that regular physical activity is an effective way to equip your body against the worst outcomes of infection.

    Hi Vivian
    Thanks for all advises.
    How does sauna help for person with osteoporosis? If it does, which one is recommended, traditional steam or FIR (infrared)? I would like to purchase one.
    Thanks

    I have a question about the study results that say “except for age and organ transplant….”. My question is what age makes the study results irrelevant? Just curious since I am 76 years old. I do at least 150 minutes of physical activity every week.

    • Vivian Goldschmidt, MA

      Marilyn, they don’t specify the age, but they’re referring to advanced age. This is what they wrote:

      “Other than advanced age and a history of organ transplant, physical inactivity was the strongest risk factor for severe COVID-19 outcomes.”

    Thank you for all your tips and good advice.

    • Vivian Goldschmidt, MA

      It’s my pleasure, Albine!

    Thank you Vivian for another great bone health vidoe, I so appreciate you and all the articles you inform us with, as well as all you do for us!
    I just need some advise Vivian. My sister in-law is in age nursing care, and since the 30th of May no one can visit their family or friends in these nursing homes unless they receive the flu vacinne. Is this vacvine safe Vivian, especially for those who want to care for their bones but want to visit their loved ones in one of these nursing home. I have avoided having this vacvine and I truly am not happy about being force to make this decision. Thank you Vivian, appreciate your help! 😊🙌

    I miss my water aerobics which I did 1 hour twice a week. But now during lockup I have to stay home and just do some gentle bouncing on my rebounder/ mini trampoline daily 20 minutes – half an hour
    Twice daily. I hope this will help my bones to stay strong

    • bonnie darby

      Dear Brigitte i do the same as you – i use my cellercise rebounder for gentle self weight bouncing to get my entire body – outside & inside moving for health 🙂
      GOD BLESS t

      Unfortunately, the lockdowns have caused many disruptions in the pursuit of fitness, but rebounding is a good exercise. Take a look at this article that explains more about it:

    Thank you for your information. I did have Covid and I did exercise. I was very glad that I had a mild case.

    • Vivian Goldschmidt, MA

      You’re welcome! And I’m so glad you had a mild case, Marguerite! Keep up with your exercise routine 🙂
