Answer:
True.
Step-by-step explanation:
When it comes to improving muscle force, the intensity of the overload plays a significant role. The overload refers to the resistance or load placed on the muscles during an exercise. The overload must be sufficient to challenge the muscles beyond their current capabilities to promote muscle strength and force improvements. This can be achieved by gradually increasing the resistance, such as using heavier weights or increasing the difficulty of the exercise.
The type of contraction, on the other hand, refers to how the muscle fibers are activated during the exercise. There are two main types of contractions: concentric and eccentric. Concentric contractions involve the muscle shortening while producing force, such as when lifting a weight. Eccentric contractions involve the muscle lengthening while producing force, such as when weight lowering. Both types of contractions contribute to muscle force improvements.
However, research suggests that the intensity of the overload has a more significant influence on muscle force improvements compared to the specific type of contraction. The muscles must be challenged with sufficient resistance to stimulate growth and adaptation. By progressively increasing the intensity of the overload, the muscles are forced to adapt and become stronger over time.
In summary, improvements in muscle force are primarily determined by the intensity of the overload rather than the type of contraction. While both concentric and eccentric contractions contribute to muscle force improvements, the progressive increase in resistance or load plays a more significant role in stimulating muscle growth and strength.
