New biomedical research proves why everyone over age 50 should be training for the Senior Games.

Research discoveries in 2002 show that we can unleash the most powerful body fat-cutting, muscle-toning, anti-aging substance known to science, naturally, with specific types of exercise, and the workouts necessary in training for many of the Senior Games events do the job.

The American Heart Association recently cited research showing that high-intensity exercise can significantly lower the risk of heart disease. Simply, as exercise intensity goes up, the risk of heart disease goes down.

The researchers compared the impact of different levels of exercise intensity on men with an average age of 66. The subjects in the high-intensity exercise group produced a 31 percent risk reduction for heart disease, which was 14 percent better than those who performed less intense exercise.

"The harder one exercises ... the lower the risk of heart disease," says lead researcher Dr. I-Min Lee, associate professor Harvard Medical School.

Anti-aging exercise

Anaerobic exercise (as contrasted with aerobic exercise) involves short, high-intensity sprint training, rather than endurance training.

Researchers show that high-intensity anaerobic workouts that include the short-burst get-you-out-of-breath sprinting types of exercise make your body release significant amounts of growth hormone (Impact of acute exercise intensity on pulsatile growth hormone release in men, 2000, Pritzlaff).

As children, growth hormone (HGH) makes us grow taller, but when we reach our full height, this hormone actually changes roles. When we’re adults, increasing HGH reduces body fat and trims inches. Growth hormone actually becomes the “fitness hormone” for middle-aged and older adults.

New studies show that HGH can be increased by as much as 530 percent with the anaerobic exercise of sprinting, (The time course of the human growth hormone response to a 6s and a 30s cycle ergometer sprint, 2002, Stokes).

Anaerobic sprint workouts can be involve many sports, including running, swimming, cycling, cross-country skiing, and all these are Senior Games events.

Whatever you do, don't do this!

Don’t jump in, ease in to anaerobic exercise. Anaerobic fitness training is clearly the most productive, but it’s also the most dangerous. Hamstring pulls are a painful potential injury, so flexibility training is essential to every fitness plan.

Everyone, especially those with heart conditions or medical problems, should get physician clearance before performing anaerobic exercise. Even young athletes should progressively ease into high-intensity anaerobic workouts.

Older adults get results with less effort

When you see an 80-year-old participant running a 10-K or working out in the gym, don't think that it's unfortunate that she can't run as fast or lift as much as her 60-year-old counterparts. It's easier for her to reach higher intensities.

The American Heart Association study proves that exercise intensity is relative to a person’s age and fitness level. In other words, an older person can reach high-intensity levels with an effort level that might be considered low-intensity for a young athlete.

The new study confirms the need for higher intensities, but it also shows that beginners and older adults reach the more productive levels of exercise intensity with less effort than a triathlete, for example.

Newcomers to high-intensity exercise may initially get great results by performing the anaerobic training with power walking, but a fine-tuned triathlete may need more work for the same results.

If you’re over age 50, get physician clearance first, select a Senior Games event or two and get started with a gradual buildup training program.
