 In the papers published in the first week of May we seem to have a range of topic discussed from the fields of fitness, nutrition and exercise science. See which one is more relevant to your personal training clients. The highlights:
Fish oil supplements and heart rhythm disorder: New analysis Omega-3 supplements are associated with an increased likelihood of developing atrial fibrillation in people with high blood lipids, according to a new analysis. Source: European Society of Cardiology More sleep or more exercise: the best time trade-offs for children's health More sleep could offset children's excess indulgence over the school holidays as new research shows that the same decline in body mass index may be achieved by either extra sleep or extra exercise. Source: University of South Australia Your stomach may be the secret to fighting obesity Scientists believe a stomach-specific protein plays a major role in the progression of obesity, according to new research. The study could help with development of therapeutics that would help individuals struggling with achieving and maintaining weight loss. Source: Indiana University School of Medicine One cup of leafy green vegetables a day lowers risk of heart disease New research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease. Source: Edith Cowan University HEPA filter effectively reduces airborne respiratory particles generated during vigorous exercise, researchers find A pair of studies shed light on something that is typically difficult to see with the eye: respiratory aerosols. Such aerosol particles of varying sizes are a common component of breath, and they are a typical mode of transmission for respiratory viruses like COVID-19 to spread to other people and surfaces.

But a Mediterranean diet rich in fish, vegetables and olive oil might protect the brain from these disease triggers.

Researchers now document how to effectively achieve and maintain a healthy weight loss.

A new study has found a link between drinking sugar-sweetened beverages and an increased risk of developing colorectal cancer in women under age 50. The findings suggest that heavy consumption of sugary drinks during adolescence (ages 13 to 18) and adulthood can increase the disease risk.

Over the years, physicians and historians have attributed Shackleton's failing health during his Antarctic expeditions to scurvy or a congenital heart defect. By studying other explorers and learning they had symptoms comparable to those of Shackleton, researchers concluded that beriberi provided a sound scientific and medical explanation for the famed explorer's health struggles.
