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.
Effects of Olympics on athlete mental health exceed the competition itself
About one-third of elite athletes globally experienced symptoms of anxiety or depression, as per a study. The quality of performance showed a direct impact on post-Olympic health. Athletes who were happy with their performance had a positive post-game phase. Pre-Olympic planning of what to do next and social support was crucial for post-Olympic well being.
Sturdy plastic helmet prototype for safe cycling experience
Researchers developed a helmet outer shell made of a new acrylic thermoplastic resin Elium by reinfusing it with carbon fiber. It is safer for cyclists as it absorbs more impact over a longer period to dissipate it evenly throughout the helmet, ultimately lowering the risk of critical injuries. It could provide protection similar to top-tier helmets but at lower prices.

Dietary supplements could cause severe liver injures
Herbal and dietary supplements, which claimed to promote muscle growth or weight loss, caused severe liver injuries, and few people were severely harmed, requiring liver transplantation, as per a study. Supplements induced liver injuries increased from 15% to 47% during 2009-2011 to 2018-2020. Also, transplant-free survival was complicated in the patients.
