The following table shows one classification scheme. Before you apply this chart to your specific situation, it is important to realize that many sports can fall within several categories, depending on the intensity of your participation. It is essential to talk to your doctor about the sports and activities that are safe for you, and how to monitor your exertion level so that exercise remains safe throughout your involvement. People with the Marfan syndrome should always avoid contact sports because of the risk of damaging the aorta and injuring the eyes. Strenuous activities also should be avoided because of the stress placed on the aorta.
Every activity has gradations, and no recommendation holds in all circumstances.
For example, shooting baskets in the driveway is different from playing a full-court basketball game, and bicycling 10 miles in one hour on a level course is different from competing in a triathlon. To maximize safety of low intensity, non-contact activities, it is important to take necessary precautions, such as not carrying a heavy bag of golf clubs, and to avoid intense competitive efforts. Before beginning or increasing any exercise program, it is important to assess your current level of physical fitness, your health and your medications. The advice offered here is general, and is not meant to substitute for the recommendations of your personal physician. Many people with the Marfan syndrome take a beta-blocker medication to reduce stress on the aorta.
