Final answer:
The dynamic systems theory views variability as an important aspect of movement, while the motor program theory aims to minimize variability for precise control.
Step-by-step explanation:
The dynamic systems theory and motor program theory are two different viewpoints on how movement is controlled in the body. In the dynamic systems theory, movement is seen as a complex interaction between multiple systems, including the nervous system, muscles, and environment. Variability is considered an essential aspect of movement in this theory, as it allows for adaptability and flexibility in different situations.
On the other hand, the motor program theory suggests that movement is primarily governed by predefined motor programs stored in the brain, which are executed to produce specific actions. In this theory, variability is seen as a potential source of error and is minimized to ensure consistent and precise movement.
Overall, the dynamic systems theory embraces variability as an important feature of movement, while the motor program theory aims to minimize variability for precise control.
