Feeling the lingering effects of COVID-19? A recent study reveals a surprising ally in the fight against long-term symptoms: resistance exercise. This isn't just about building muscle; it's about reclaiming your life.
Published in JAMA Network Open, a randomized clinical trial involving 233 adults offered compelling evidence. Researchers from the University of Glasgow led a study spanning from June 2021 to April 2024, focusing on Scottish adults who had experienced COVID-19 in the preceding year. The goal? To understand how resistance exercise impacts exercise capacity, overall health, and safety.
The study divided participants into two groups: one receiving a personalized 3-month resistance exercise program and the other receiving standard care. The results were striking. Participants in the exercise group showed significant improvements in physical function, well-being, and quality of life.
But here's where it gets interesting: the intervention group consisted of 117 individuals, while the control group had 116. At the beginning of the study, 224 patients participated in the Incremental Shuttle Walk Tests, with 193 completing them at the three-month mark. Questionnaires were used to assess health-related quality of life (HRQoL), anxiety, depression, and grip strength.
The researchers noted that long COVID can impair physical function and energy levels in skeletal muscles. They also pointed out that inactivity often leads to reduced muscle mass and function, which can be improved with resistance exercise.
The average patient age was 53.6 years old, with 62.7% being women, and 93.1% identifying as White. 39.1% had been hospitalized. The average adherence to the exercise program was 71.0%, meaning participants completed the exercises approximately 5 days a week. This pragmatic approach could potentially become a widely applicable therapy for those still dealing with physical symptoms after a COVID-19 infection.
And this is the part most people miss: The average distance covered in the shuttle walk test increased from 328 meters (359 yards) at the start to 389 meters (425 yards) at the follow-up. The exercise group saw an average increase of 83 meters (91 yards), compared to 47 meters (51 yards) in the control group.
Furthermore, the exercise group experienced greater improvements in HRQoL, a reduction in depression and anxiety, and enhanced handgrip strength compared to the control group.
Importantly, there were no deaths or hospitalizations related to the exercise intervention. Although post-exertional malaise was reported by a similar percentage of both groups (83.3% in the intervention group and 82.4% in the control group), the overall benefits of the exercise program were clear.
Switching gears, let's look at some other health-related news:
Avian Flu Update: The US Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has reported seven more cases of avian flu on commercial poultry farms. This includes three farms in Lagrange County, Indiana, which has had six major outbreaks since late October. Two duck meat farms (with 8,400 and 8,300 birds, respectively) and a table egg-layer facility (with 18,300 birds) in Lagrange County have been affected. A turkey meat farm in Allegan County, Michigan, with 35,600 birds, was also hit. Backyard flocks in California, Oregon, and Virginia have also been infected. Over the past 30 days, highly pathogenic avian flu has been confirmed in 31 commercial flocks and 31 backyard flocks across the US. Indiana, Michigan, and Minnesota are the hardest hit, with at least 1.65 million birds affected nationwide.
Infant Botulism Cases: The Associated Press reports two more infant botulism cases linked to ByHeart infant formula, bringing the total to 15 cases across 12 states since August. All affected infants, aged 2 weeks to 5 months, have required hospitalization, but there have been no deaths.
Measles on the Rise: Louisiana has confirmed its third measles case, with exposure occurring during international travel. The individual was infectious at the Louis Armstrong New Orleans International Airport over the weekend. Meanwhile, Tennessee has reported its eighth measles case this year, the most in a decade. The patient was unvaccinated and had recently traveled. This is Nashville's first case in 20 years.
Ebola Outbreak: The Democratic Republic of the Congo (DRC) is nearing the end of its recent Ebola outbreak, with today marking the halfway point in the 42-day countdown to officially declaring it over. The outbreak involved 64 confirmed or probable Ebola cases and 45 deaths.
