Athletes should keep these in mind when creating a sports specific training program. Other factors like the athletes’ age, sex, nutrition, motivation and prior fitness level prior to training can also have an impact on training adaptations.īelow is a list of specific adaptations that are acquired due to the imposed demands of aerobic & anaerobic training.

Optimal adaptations reflect careful planning, implementing and performance of conditioning and strength programs. Specific adaptations observed in athletes are directly related to the quality and specificity of the aerobic & anaerobic stimulus within their training programs.

The SAID Principle is the bases for physiological changes due to the imposed demands of the specific training stimuli.Īn athlete must design a training program in order to meet the needs of their specific sport. Specific adaptations are known to take place in the human body in response to specific types of stimuli. The SAID Principle, the principle of specific adaptations to imposed demands is the foundation for sport specific training. There are many basic principles of physical training an athlete must utilize for optimal results within their training program. Ric Esposito, Chair of Sports Medicine, USSA
