Don't Overdo It: Why Too Much Exercise May Be a Bad Thing
Two recent studies have shed light on the impact of over-exercising, encouraging seasoned athletes and casual enthusiasts alike to take it easy. The first has identified the biochemical reactions that cause muscle pain and fatigue when you work out, and the second shows that wealthier, young athletes with who play specialized sports can experience more overuse injuries than their lower-income peers. “If there are exercises you haven’t done, it may be helpful to work initially with a physical therapist, certified athletic trainer, or personal trainer. They can show you exercises, make sure you are doing them safely and effectively, and give you a basic regimen to start with,” said Jonathan Kirschner, MD, Assistant Professor of Rehabilitation Medicine at the Icahn School of Medicine at Mount Sinai.
