. Fitness test. Tae kwon do athletes being tested for fitness. They are breathing into masks that measure their oxygen consumption. The equipment they are wearing on their backs allows a number of other physiological parameters to be measured. The resulting data can be used to determine the ability of the body to cope with exertion, and to develop personal fitness regimes for the athletes. Tae kwon do is a martial art based on self-discipline and self-defence. Photographed at the Centro Sportivo, Rome, Italy. MODEL RELEASED
