5. Variable Resistance Profiles
Variable resistance profiles represent a significant advantage of plate-loaded squat machines, offering training customization beyond traditional free weights or fixed-resistance machines. This variability stems from the capacity to manipulate resistance throughout the squat’s range of motion, accommodating strength curves and addressing specific training goals. Several factors contribute to this adaptability.
Firstly, accommodating resistance, achievable through the use of chains or resistance bands, alters the weight lifted throughout the movement. Chains, for example, increase resistance as more links lift off the floor during the ascent, matching the strength curve of the squat where individuals are typically stronger in the upper portion of the lift. This challenges the lifter throughout the entire range of motion, promoting consistent muscle activation and strength development. Consider a powerlifter aiming to improve lockout strength; incorporating chains provides targeted resistance at the top of the squat, addressing this specific need.
Secondly, bar placement influences muscle activation patterns and resistance profiles.
