Is there any truth to the below? When I browse the internet for this topic I get pretty much only the type of information that contradicts Peat...
"Long distance runners are the only group of athletes that have a longer life span than non-athletes, according to “The End of Ohm: A Science Fantasy for Overcoming Resistance to Lifestyle Change." Rigorous endurance training can improve your cardiovascular system, leading to increases in your VO2 max -- the maximal amount of oxygen uptake -- blood flow and the number of capillaries that supply blood to your muscles. In addition, the muscles of distance runners have more mitochondria, or the powerhouses in a cell that use oxygen to produce energy. In contrast, the muscles of sprinters have fewer mitochondria but a greater number of enzymes required for glycolysis -- a process that breaks down carbohydrates for energy and doesn’t require oxygen."
