Brief Summary:
The proprioceptive system and strength are closely related within the sensorimotor system: proprioception enables effective and coordinated muscle activation (including intramuscular and intermuscular coordination or synergistic abilities), which is essential for maintaining the functional stability of joints and preventing injuries-in short, for controlling motor patterns. This principle provides a window through which changes in strength can be observed via peripheral proprioceptive stimulation that activates the muscular system with the goal of increasing recruitment. This justifies the implementation of proprioceptive input in approaches aimed at motor learning.
Detailed Description:
Objective: To determine whether the application of a peripheral proprioceptive stimulus to the neuromuscular motor points of the quadriceps increases strength and neuromuscular activation during the squat movement in the lower limbs of healthy, untrained subjects.
Methods: The design of this study is a randomized crossover clinical trial. All participants (n=36) will randomly receive both the Active and Sham proprioceptive stimulation.The proprioceptive stimulus will consist of intermittent mechanical pressure on the skin, localized at the neuromuscular motor points of the rectus femoris, vastus lateralis, and vastus medialis of the quadriceps. The tissue subjected to precise pressure in these highly innervated neuromuscular zones promotes the stimulation of kinesthetic cortical sensitivity. The outcome variable will be the assessment of Maximum Strength (MS) generated by the participant during the squat movement, from a 90ยบ knee flexion position to full extension. At the moment of peak force, the mean velocity (MV) of the concentric phase of the movement and the maximum load the participant can move will be evaluated. The intervention, assessment, and recruitment will take place at the Faculty of Health Sciences, Blanquerna - Ramon Llull University
