Does running on a treadmill cause damage to the body?

Answer 1

From a highly technical perspective, yes. Then again, so does breathing or eating. Running on a treadmill (or any exercise for that matter) will generate free radicals, which are known to cause cellular damage. The entire theory supporting antioxidant consumption is that by blocking these free radicals, you could reduce cellular damage and slow the aging process. That fatigued feeling you have after running for a while is a result of lactic acid buildup, caused by a temporary insufficiency of oxygen. Your muscles will feel sore from this exercise as they recover from the damage, generating more free radicals in the process. So does running on a treadmill damage the body? Yes. Is running on a treadmill for a while (under 90 minutes at moderate intensity) bad for you? No! The exact role that free radicals have in the benefits of exercise is not known, but given the reduced risk of heart attack, stroke, cancer and increased endurance and life expectancy amongst those who exercise daily, it's safe to say that this damage from moderate intensity cardiovascular exercise is either negligible in comparison to the benefits or that the damage actually plays a role in conferring the benefits of exercise. It seems paradoxical that preventing the generation of free radicals can be beneficial, yet engaging in an activity that creates more free radicals is also beneficial as well. One interesting observation: trained athletes produce far fewer radicals when not exercising as compared to untrained persons. So it's possible that this increased radical generation during exercise "trains" the body to produce fewer radicals over time, much like increasing your heart rate during exercise will eventually result in a lower heart rate at rest. More research is needed to really understand the role of radicals during exercise, but the advice is still very clear: get at least 30-60 minutes of moderate intensity cardiovascular exercise a day while consuming a diet rich in whole grains, fruits,vegetables and sufficient in lean protein and monounsaturated fats.

Answer 2

Treadmills have a kill wire that you attach to yourself. Make certain that you use it.Treadmills are pretty safe. Be sure to start the treadmill slowly and with you on the treadmill with your hands on the rails. The most dangerous thing you can do is try to jump onto a moving treadmill.
