Document Summary
For some individuals, exercise can be dangerous. Sometimes can use exercise danger as an excuse not to participate. Example of a book that claimed these. Other rf: smoke, overweight, we don"t know about his diet, family history. In fact running could have delayed his death (father died 35 due to heart attack) There are risks associated to exercise to certain individuals, but not exercise itself. If individual have underlying cvd = complication -> exertion -> causes problem. Only when already unhealthy, then exercise will cause problems. More likely to happen at exercising than rest if already have underlying problem (since heart have to work harder) If exercise regularly, then overall risk of heart problems is lower. Young athletes = usually underlying congenital structural abnormality of heart. Since heart inside of body, generally don"t know until issues arise. >40 y/o athletes: most common cause is coronary atherosclerosis.
