It feels like we've lived with COVID-19, the virus which sparked a global pandemic, for much longer than 20 months. The impacts of the following health crisis have dominated headlines worldwide, making it difficult to avoid and even harder to forget.
Thanks to lockdowns and business closures, many of us invested in the best workout equipment for home so that we could stay active without going out. According to a new study, this might have been a good decision, as there's evidence that stronger muscles may aid recovery if you do catch the virus.
Researchers at the University of São Paulo in Brazil explored (opens in new tab) whether muscle strength and mass could lead to better health outcomes after infection. The study looked at the data of 186 hospitalized patients who tested positive for the disease.
The research found that the overall length of stay in hospital was shorter in those with the greatest handgrip strength, a proxy for overall muscle strength. Similarly, the team used the size of the thigh muscle as an alternative measurement for muscle mass and found similar results.
What's important to note is that the research did not show that strength training develops any form of immunity to COVID-19. The study only included people that had already contracted the virus and were sick enough to warrant hospitalization.
When discussing the results, the authors noted that they chose to look at these two measures because muscle mass and muscle strength have previously been linked to better health outcomes more generally.
When you're severely ill, your body breaks down some muscle to generate amino acids for the immune system. So it figures that those with lower muscle mass will be more vulnerable to the effects of the virus.
Similarly, the discussion around muscle strength notes that this is critical to post-disease recovery. When combined, the immune support offered by higher muscle mass and improved recovery thanks to stronger muscles helps reduce the length of time the participants spent in the hospital.
As SARS-CoV-2, the virus that causes COVID-19 symptoms, is relatively new, there haven't been many opportunities to connect symptoms and lifestyles. However, one late-2020 study (opens in new tab) established a link between the severity of the disease and Vitamin D levels.
We get most of our daily allowance of the vitamin after exposure to sunlight, but as the seasons are shifting into fall and winter, it's worth including some of the Vitamin D foods in your diet to stay topped up.
Of course, there are plenty of great reasons to pick up a set of the best adjustable dumbbells and start building muscle. Alongside possible improvements in recovery from disease, stronger muscles help improve energy levels, support our posture, and reduce the risk of injury, especially in later life.
