This is the first time we've been able to document this kind of enhancement associated with exercise.

This is important because if an obese person begins an exercise program, he may not cognitively experience pain when in fact it is hurting the body on some level. That could lead to severe pain down the road.

The findings from both studies indicate that the effect of exercise we found in the current study truly represents an enhanced rate of wound healing in older adults.

Exercise increases circulation and helps regulate the immune system and hormones that influence the healing process.

This kind of evaluation is in some ways a more objective way of measuring the body's response to pain, as opposed to simply asking someone if they feel pain.
