Resistance Training Apparatuses: Understanding Dynamic Variable Resistance

Which resistance training apparatus supports dynamic variable resistance?

a. Squat machines

b. Cam-based machine weights

c. Barbells

d. Unweighted treadmill

Answer:

Cam-based machine weights support dynamic variable resistance, providing less resistance at certain points of the movement.

The apparatus that supports dynamic variable resistance (less resistance at certain points of the movement) is cam-based machine weights. These machines have a cam mechanism that alters the resistance throughout the range of motion, providing a varying level of resistance based on the mechanical design. This allows the user to experience less resistance at certain points of the exercise, which can be beneficial for targeting specific muscle groups or accommodating individual strength curves.

On the other hand, squat machines typically provide a constant level of resistance throughout the movement. Barbells offer a fixed weight, and the resistance remains the same unless additional weights are added or removed. Unweighted treadmills, as the name suggests, do not provide any resistance for resistance training.

It's important to understand the different types of resistance training apparatuses and how they can impact your workout routine. Cam-based machine weights are a great option for those looking to incorporate dynamic variable resistance into their training regimen.
