That’s the theory behind “overreaching,” a training strategy followed by most competitive athletes today. “You push the body up to the breaking point,” Reiff says. “At least, that’s what you try to do.” Overreaching is often part of a months-long regimen that ends with tapering: doing only light workouts in the days before a big event. If all has gone well, athletes will, at that point, be at their physiological peak.

But all doesn’t always go well. “You expect a peak, but you get a slump,” Reiff says. Why? According to one hypothesis, constant training leads to overactive cytokines. These proteins may communicate with circulating blood cells and cause them to ramp up the production of chemicals that can inflame the whole body. Instead of being confined to the wounded muscle tissue, inflammation becomes systemic. This theory (hard to test, since no coach is likely to allow a scientist to induce overtraining in his athletes) may explain the wide range of symptoms often seen in overtrained athletes: mood changes, apathy, insomnia and fatigue. Overtrained athletes often lose weight, possibly because of decreased appetite, and they can have low levels of ferritin, a protein complex that helps store iron in the body. They can experience a rise in resting heart rate, which is one of the surest signs of overtraining, or have especially viscous blood. Some researchers believe this sludgy blood accounts for the odd heaviness in the legs that overtrained athletes report.

Genetics, not surprisingly, is thought to play a role in the onset and severity of overtraining. Research that is currently under way at Baylor University in Dallas, and funded by USA Track & Field, suggests that hard, competitive training of any kind can alter the ways in which a wide array of genes work. Genes of well-trained athletes are thought to encode proteins that prompt the body to produce chemicals that, in turn, increase the levels of certain enzymes and stimulate other processes necessary for creating speed and endurance. It’s an elegant cycle: the demands of the straining body activate genes that produce the means of making that body stronger, tougher and faster.

Baylor scientists have taken blood samples from elite American distance runners in an attempt to determine whether some genes become either exceptionally active or suddenly quiescent when an athlete nears his or her fitness limit. The irregular activity of these genes may be the cause of overtraining, or it may be that the genetic changes are only the first, microscopic symptom of its onset. If further research shows the same genes at work in those who are overtrained, blood tests may soon substitute for guesswork among coaches and athletes. “Right now, we use trial and error to get someone as fit as possible without going too far,” Larsen says. “It’s more art than science. It would be great if it became more science.”

There is, however, no mystery about how to treat overtraining. “There’s only one palliative for overtraining that I know of,” says Robert Schoene, a professor of medicine at the University of California, San Diego, who has written about overtraining and has treated afflicted athletes. “Rest, rest and more rest.”

This prescription can be difficult for athletes to accept. Many of them will instead stubbornly try to train harder. “You keep thinking, ‘I can push through this,’ ” Whitney Myers says. Last summer, she dutifully showed up at the pool, twice a day, for weeks, even as her body could barely complete a lap.

But rest does allow the body to heal, in time. “I used to tell the overtrained athletes I saw that we really didn’t understand what was wrong with them,” Schoene says, “but they could get better. I’d tell them to cut down on training and have fun.

Be patient.” Once the most debilitating fatigue has passed, athletes can resume workouts — slowly. Full recovery can take months. “The human body, no matter how strong and fit it is, must rest,” Schoene says. “If you don’t rest it some of the time during training, you’ll be resting it all of the time during recovery from overtraining.” The marathoner Alberto Salazar is famous among runners for having permanently compromised his health and shortened his career by overtraining. “Alberto gets used as a worst-case example, to scare runners into taking it easy sometimes,” Larsen says. Myers, who’s studying to be a pharmacist, finally learned her lesson late last summer. “I had to step back from swimming for a while,” she says. “I did a little jogging, but didn’t go to the pool or the gym.” (She filled her spare time admirably: in October, she was named the N.C.A.A.’s 2007 Woman of the Year for her academic and community work, as well as for athletics.) Finally, after weeks away, she returned to the water last fall and, in her most recent meets, has approached some of her previous best times. “I’m not all the way back,” she says, “but I’m encouraged.”

This summer, she hopes to swim well enough at the United States Olympic trials to qualify for the games in Beijing. But as someone intimate with overtraining, she knows that moderation has its price, too — at least socially. “I’m 23 years old. I’m a college student.” She sighs. “And I’m in bed every night by 9 o’clock.”

How to Tell If You’re Overtraining

A FEW SIGNS THAT YOU SHOULD SEE A DOCTOR AND HEAD FOR THE BARCALOUNGER.

Fatigue that persists for more than 72 hours after a workout, often accompanied by insomnia.

Muscle pain and weakness that persist for more than three days.

Irritability, anxiety, depression. Unsure if you’re being extra-moody? Ask your significant other.

A rise in resting heart rate. Track yours by wearing a heart-rate monitor to bed.

A dramatic drop-off in performance for no obvious reason.

“Heavy legs,” or the feeling that your lower limbs, once springy and quick, have turned to stone.

A loss of appetite, which exacerbates fatigue by sapping the body’s fuel stores.

Disruptions in the menstrual cycle.

Cuts and bruises that heal slowly; overtraining might suppress your immune system.

Falling levels of ferritin — a protein complex that stores iron — as revealed by blood work.

Not many colds. True, it’s not normally a sign that you need to see a doctor, but athletes are more likely to overtrain if they manage to avoid viruses. A cold ruthlessly forces the body to slow down and thus prevents overtraining. G.R.
