As recent as a decade ago sport relied heavily on information passed down from competitor to competitor. To lose bodyfat it was suggested to guzzle soft drinks. We were told, "They burn up the fat". For breakfast we were advised to eat a concoction of raw egg and ginseng. Sometimes water was witheld during strenuous workouts to toughen us. Experts said, "Train more, train harder."

Many worked hard; training for a specific purpose or event. If they didn't see improvement, they tried harder. The harder they tried, the more tension and anxiety they felt. They maximized the value of every jump or stretch in order to justify the time expenditure - even if their purpose for training was stress management or peace of mind.

Some enthusiasts trained so frequently they developed overuse injuries. They thought they must push beyond their normal limits to get to the next level. Elbows, knees, and backs simply wore out. Immune systems became impaired with too much training, leading to colds, flu, and other infections.

Others burned out psychologically. Their lives revolved around sport. Relationships and jobs suffered. All they thought about was training and competition. Training was like drinking a glass of wine. A little bit with each meal was fine, but too much and they became alcoholics.

I received both truth and fiction from my early mentors. Before a professional full-contact fight my trainer rubbed Ben Gay all over me. I was on fire. I came out so hard and fast I had no punches or kicks left for the last round. Fortunately neither did my opponent. Two weeks prior to the World Taekwondo Championships in Stuttgart, we trained on German time. We set our alarms for 2:00 a.m., trained all day and tried to sleep at 7:00 p.m. Most of us were sleep deprived and miserable. We neglected to consider late flights or layovers. By the time we reached Germany it took several days for our overtrained bodies to recover from severe jet lag.

It's easy to eat, sleep, and drink sports. You can stretch, run, ride, cross-train with weights/aerobics, and watch instructional videos. There seems to be a point of diminishing returns to excessive training, however. Athletes sometimes neglect the recovery phase of their workouts.

Most mammals are on a strict schedule of activity and recovery. Cats are notorious for lounging, but when it's time for action they pounce. Sport is high intensity too, requiring rest periods between bursts of activity. Rejuvenate yourself between bouts of exertion. Intense effort is followed by recovery, where you prepare for your next campaign. The goal is to maximize intensity and increase your capacity to handle it. Set performance goals to determine training time and energy expenditure. But goal setting is a double edged sword. Effortless ambitions aren't worthy. And if your goal is too extravagant it becomes your personal nightmare.

Daily training should be motivational and energetic. Be sure you are on track.Enjoy a vibrant lifestyle.Attaining short term goals provides you confidence for the long haul. Eating correctly, sleeping enough, and incremental improvements in strength, flexibility, and endurance can be measured. These assessments should satisfy you day-to-day.

Pushing to the limit feels good. But maybe that is wrong. Contemporary athletes follow season long-training schedules. They know exactly how much time to jump rope, lift weights, run, and stretch from January until December. And then they start all over again. They claim they need structure in their training to have an idea of what they can accomplish. This style of training is called "periodization."

In 1999 elite competitors realize the benefits of force pads, SportCords, and heart rate monitors to regulate their training. Anaerobic threshold, maximum heart rate, pressure indicators, and digitized biomechanical analysis, allow athletes to maximize their training time. More and more contemporary competitors believe in scientific training. A little technology can reveal signs of overtraining.

Signs of over training include:

1. Elevated heart rate. If your heart rate is higher than normal when you awaken, you may be over training.

2. Negative attitude. Inadequate recovery from training may lead to listlessness.

3. Weight loss. Overtraining can lead to muscle loss and weakness.

4. Lack of recovery. After a sporting event you may recover slowly if you are over trained because your immune system is depressed.

5. Loss of interest. Over training leads to boredom and lack of commitment.

6. Fatigue. Over training causes fatigue from even a mild training session.

7. Injury. Over training may cause overuse injuries and muscle pain.

There is more to training than demonstrating your genetic giftedness. Pacing is extremely important to exemplary performance. Knowing when to turn it on and when to rest can help you enjoy sports, reach optimal physical condition, and be your best. The hard part is distinguishing overtraining from laziness.
