What is meant by Dynamic Constant Resistance?

1. Resistance that varies throughout the exercise

2. Resistance that remains constant during the entire range of motion

3. Resistance that decreases with fatigue

4. Resistance that increases with each repetition

The correct answer is: Resistance that remains constant during the entire range of motion

Dynamic Constant Resistance refers to a type of resistance training where the load applied during an exercise remains constant throughout the entire range of motion regardless of the position of the muscle being worked. This means that the same amount of weight or resistance is used whether the muscle is in a strong position or a weaker one during the movement. This concept is significant because it allows for consistent training loads, contributing to strength development and muscle endurance over time. By maintaining even resistance throughout the exercise, individuals can develop their muscular strength effectively without the complications of varying resistance levels which can affect the performance and outcomes of a workout. Other options present variations or misunderstandings regarding how resistance functions. Resistance that varies throughout the exercise, for example, implies that the load is inconsistent, which does not align with the definition of Dynamic Constant Resistance. Additionally, resistance decreasing with fatigue or increasing with each repetition introduces the concept of progressive overload or fatigue management, which are different concepts entirely.
