You've probably suspected some people get more out of exercise than others. In certain respects you're right.
Now there's a groundbreaking new study out of Baton Rouge's own Pennington Biomedical Research Center. Researchers have pinpointed a genetic profile that not only identifies people who are more able to tolerate long bouts of aerobic exercise. They respond to it better. Dr. Claude Bouchard of the Pennington Center was part of the International team of scientists that made the discovery.
Among other things, it could tell doctors which patients will respond better to exercise rehab programs aimed at preventing second heart attacks. Bouchard says such a predictor will tell you some of your patients might not benefit much, while others will do tremendously. Heart patients who don't benefit as much from standardized exercise programs may do better with a more intense work out or aggressive drug therapy.
The military may even use the genetic profile as a screening tool to tell them which recruits are not likely to build the endurance necessary to complete basic training.
But, don't throw the baby out with the bath water. Bouchard says his test mainly predicts endurance and performance. The average person can still benefit from exercise. He says you may improve your blood sugar, cholesterol, blood pressure and burn calories in the process.
The study was published today online in the Journal of Applied Physiology.
