What is VRT？
Variable resistance training (VRT), or dynamic variable resistance exercise, is a type of strength training that applies a dynamic degree of force to the target muscle(s). Variable resistance mimics the natural curve of the body's strength capability as it passes through a range of motion. Variable resistance training compels muscles to work harder when they are strongest, to meet the demands of the exercise.
Physiological and BiomechanicalMechanisms
Gradualy increasing external resisfance can cause instability during training, which optimizes muscle strenath qrowtitimuli and incregses neUruscular control demands, This leads to areater mofor unit recruitment and rate coding.likely improving coordination agonistic and antagonistic muscles, Variable resistance trainina /VRT) heiahtload variability and instability, enhancing neural adaptations, motor unit recruitment, and muscle coordination. Theseimprovements boost muscle srength performance, including l R and RFD, while also enhancing faigue resistance isome trainees.
VRT Biomechanical Characteristics
A sticking point in resistance training is a speed loss during movement, typically occurring between 35% and 45% of the range of motion. This region is the least efficient, especially when loads reach 80%-90% of 1RM, as muscles struggle to meet demands. Recent research shows that VRT can increase RFD and muscle strength more effectively than traditional training by enhancing neural impulses and muscle activation, leading to greater force generation during the final part of the concentric phase.
VRT Theoretical Foundations
In traditional resistance training, muscle force varies with joint mechanics. To address this, variable resistance equipment adjusts resistance in real-time based on joint angles, maximizing muscle output and improving power training by compensating for mechanical disadvantages and acceleration changes.
