Molecular Approaches Breathe New Life Into Sports Medicine
Sara Latta | Jul 20, 1997 | 7 min read
Now that summer is in full swing, all but the most dedicated couch potatoes are playing on departmental softball teams, hitting the tennis courts, or laboring in the garden. For a growing number of scientists, however, exercise is more than a seasonal diversion-it's the focus of a thriving discipline that integrates molecular and cellular biology, physiology, nutrition, and behavioral sciences. One important trend, not only in exercise science but also in physiology, is the integration of mole
