REVIEW ARTICLES

Windsurfing Injuries
Added Awareness of Diagnosis, Treatment, and Prevention
Though windsurfing is a relatively safe sport, injuries do occur from equipment and sometimes from extreme environmental conditions. Examples range from chronic back pain to acute lacerations. Lisfranc dislocations or fractures can occur when patients fall and their feet remain in the board straps; a case report underscores the subtle clues to look for on the physical exam and x-rays. Safety strategies, such as wearing a helmet and being aware of outdoor conditions, can mean smooth sailing for patients.

The Role of Antioxidants in Exercise and Disease Prevention
Antioxidants are a big topic among patients, especially if they're exercisers or they seek dietary supplement strategies to decrease their risk of cancer, atherosclerosis, and other aging-related conditions. It can be difficult to advise patients because research on antioxidants is often conflicting. For now, a reasonable recommendation is to advise patients to eat five to seven fruits and vegetables a day or to take a multivitamin that provides a combination of nutrients.

ORIGINAL RESEARCH

Using an Experimental Bicycle Seat to Reduce Perineal Numbness
Researchers evaluated the effectiveness of an experimental seat that was designed to prevent perineal numbness and possibly erectile dysfunction in male bicyclists. A trial of the device among 15 experienced cyclists measured perineal sensation after a 1-hour stationary cycling session on a standard seat followed several days later by the same exercise protocol on the experimental bike seat. Cyclists reported more numbness with the standard seat than with the experimental seat (79% vs 14%). Sensory testing found greater hypoesthesia with the standard seat. Innovations in bicycle seat design may decrease or eliminate perineal numbness.
