STRONGER CHEST AND BACK MUSCLES LINKED TO LOWER HEART ATTACK RISK

Research published in the journal Radiology suggests that individuals with stronger back and chest muscles may face a reduced risk of heart attacks. The study analysed scan images of 1,722 adults enrolled in the Scottish Computed Tomography of the Heart trial over a 10-year period, using artificial intelligence to assess muscle mass. Researchers found that those with below-average muscle mass recorded an 85 per cent higher risk of death and a 58 per cent higher risk of a heart attack during the follow-up period. Professor Michelle Williams, senior author of the study, noted that the finding links skeletal muscle strength to heart attack risk.

The analysis focused on muscles visible in coronary computed tomography angiography scans, including back muscles, parts of the pectoral muscles and intercostal muscles between the ribs. The researchers observed that many people neglect these muscle groups during exercise routines. In response, they consulted Edwina Jenner, a personal trainer specialising in strength training for women over 40, who provided guidance on targeted exercises. Jenner recommended dumbbell bent-over rows to strengthen back muscles and chest presses to develop chest muscles as accessible starting points for beginners.

The study suggests upper-body muscle development may have implications for cardiovascular health. The findings indicate that targeted strength training could form part of a broader approach to reducing heart attack risk. Further research would be needed to establish whether muscle-building exercise directly reduces cardiovascular events or whether muscle mass serves as a marker of overall health and fitness.
