Final answer:
Strength refers to the force a muscle can generate, while power is the ability to exert that force quickly. Both are important in sports. Testing of strength and power can alter an athlete's training, and a quadrennial training plan can be modified to address these areas.
Step-by-step explanation:
The relationship between strength and power is that strength refers to the amount of force a muscle or group of muscles can generate, while power refers to the ability to exert that force quickly. In sports, both strength and power are important. While it is possible to be strong enough for a sport, having power is also crucial for explosive movements and quick actions.
Testing of strength and power can alter an individual athlete's training macrocycle. If testing reveals that an athlete lacks strength, their training may focus more on building muscular strength. On the other hand, if power is a weakness, the training program may include exercises that improve speed and explosiveness. The quadrennial training plan can be adjusted by incorporating specific strength and power training phases to address the individual athlete's needs.
