Is it too late to start weight training?
Experts believe it is never too late to start strength training by lifting weights. Aging causes muscles to lose mass and strength, increasing the risk of high BP, diabetes, frailty, and obesity. While lifting weights can promote muscle growth even in people aged above 75 years. Even older people with arthritis, heart disease, or osteoporosis can start lifting at any age.
BJSM retracts nine more articles of their former editor in chief
Dr Paul McCrory is a famous sports medicine researcher whose editorial was retracted earlier this year due to plagiarism. The current retractions are due to shared similarities with other articles and redundancy. Dr McCrory co-authored 18 papers during his tenure, but he resigned after plagiarism allegations. The BMJ said it would investigate any additional allegations.
Gut microbial instability could hinder the athletes' performance
Short-term high-protein diets were linked to gut microbial instability resulting in a 23.3% reduction in elite athletes' time trial performance, compared to a high-carbohydrate diet, as per a study. A high-protein diet reduces gut microbial stability by reducing microbial diversity, altering gut phageome composition, and increasing specific viral and bacterial components.
Athletes could experience persistent symptoms from COVID-19
About 8.3% of athletes had persistent symptoms of COVID-19 that affected their performance and prevented them from returning to training, according to a study. These symptoms include loss of taste or smell or both (30%), cough (16%), chest pain(8%) and fatigue (9%). About 3% of athletes developed exercise intolerance after contracting COVID-19.
Do compression garments help muscles recover quickly after a workout?
Wearing compression garments after or during physical exercise does not facilitate the recovery of muscles, as per the analysis. Also, no effect was observed with compression garments on strength recovery. These findings will help therapists, coaches, athletes and practitioners to reconsider these garments as a way to lower the harmful effects of exercise on muscle strength.
A case of acute hand ischaemia associated with COVID-19 in a volleyball player
A 29-year-old man presented to an ED with acute ischaemic signs in the upper extremity. The patient was diagnosed with COVID-19 one month ago and reported repetitive trauma during volleyball training. Upper extremity catheter angiography showed high take-off occlusion in ulnar and radial arteries with the poor collateral flow. He was managed with local thrombolysis.
New tool predicts the effect of an exoskeleton in lowering the back-injury risk
A tool called Exo-LiFFT is an interactive calculator that predicts that exoskeletons can minimise occupational back injuries during material handling by 20% to 60%, as per a study. Exo-LiFFT enables safety experts to swiftly assess exoskeletons' effect on back injury risk by reducing assessment time and providing an evidence-based way to determine injury risk reduction.
A single-dose skin patch COVID-19 vaccine is more effective than jabs
A high-density microarray skin patch that delivers the COVID-19 virus's spike subunit-based vaccine directly into the skin was able to induce both antoand cellular immune responses, as per a study. Moreover, the antibodies neutralized both the Alpha and Beta variants. Also, the vaccine provided complete protection in the virus challenge test in the mice model.
Running could lead to sudden death in people with heart conditions
About 12 young individuals die due to undiagnosed heart conditions every week, as per a report. Physical activities like bike riding and running cause their heart to beat rapidly. However, these conditions can be managed with the right care. Hence, charity or Cardiac Risk in the Young is trying to screen young people for such conditions to prevent 89% of deaths.
Head impact may cause cognitive decline in rugby players after one season
A study observed that a professional team of rugby players had a decrease in blood flow to the brain and cognitive function between pre to post-season. Six concussion incidents were seen among the players over a year. But about 20% of all concussions at a professional level occur in training, as per the RFU. Recently, World Rugby vowed to double the investment in this research.
