Fitness enthusiasts don't really need an oxygen testing program to be fit, but the test can help tailor workouts to a specific fitness level. Oxygen consumption testing, or VO2 max testing, has long been used to determine elite athletes' cardiac fitness. It can be applied to everyone, says Conrad Earnest, director of the Center for Human Performance and Nutrition Research at the Cooper Institute in Dallas.

Larry Brooks had been a football player through high school and college and was athletic well into adulthood — in fact, he was a power lifter into his mid-40s. But by the time he hit his mid-50s, a busy decade of all work, no exercise and drinking as many as 35 cups of coffee each day took its toll. In December 2009, after a bout of pneumonia, the geologist from Keller, Texas, found himself with a 54-inch waist, 40.3% body fat, total cholesterol of 325 and a $300 monthly bill for Lipitor, three beta blockers and other drugs.

Debbie Bumgardner was an overworked 52-year-old legal secretary and frustrated yo-yo dieter from Tarzana who'd gradually cut back on tennis and biking over the years. By early 2010, she was 100 pounds overweight. A year later, Bumgardner is still overworked and stressed-out. But she's 70 pounds lighter, which she attributes almost entirely to Trikking. A Trikke (pronounced "trike") is a three-wheeled vehicle with foot platforms and upright handlebars that you propel in a standing position by shifting body weight from side-to-side, as if carving "S" turns while skiing.

Football has always been a way of life for Guy Liggins of the San Francisco 49ers. But after surgery Monday to temper a rare heart disorder, the former Castle Park High and Southwestern College receiver feels fortunate just to be living. And he is through with football. On June 26, Liggins, 23, was working out with a friend at San Jose State when "it just happened," he said. "My heart rate speeded up. It made me feel real dizzy, and I felt like I was going to pass out."

Alberto Contador, the 2010 Tour de France winner, had his title taken away Monday after being found guilty of doping, specifically for testing positive for clenbuterol. The drug is a beta2-agonist that works as a bronchodilator, loosening muscles that line the airways so that air can pass through more easily. It has other properties as well that are attractive to athletes, some of whom use it as a performance-enhancing drug. Clenbuterol can also increase heart rate, build lean muscle mass and promote weight loss.

They're more than heart rate monitors. Now they have names like "personal fitness computer," and they're jammed with such features as altimeters, thermometers and the capability of downloading workout data into your cellphone. They can make your workouts more efficient, whether you're a serious runner, biker or hiker or a first-time power walker in need of some coaching.

Fetal heart rate monitoring is a modern technology used in childbirth that has been highly debated. Some doctors feel the monitors, which measure the baby's heart rate during labor, provide valuable information. Others, including some studies, suggest electronic monitors are unnecessary and were adapted without concrete evidence that they're helpful. Research published Saturday comes down on the side of using monitors. Scientists examined data from the National Birth Cohort of more than 1.9 million U.S. births in which a single  baby was delivered.

Some personal trainers say that obtaining biofeedback is the best way to get the most out of your cardio training. Consisting of a chest strap that uses electrodes to detect your heart rate and a wristwatch readout that displays it as beats per minute, a heart rate monitor encourages you to stay in a heart rate target zone that is challenging enough to increase your fitness, but easy enough to avoid injury or exhaustion.
