Effect of the Ultrasound-guided Percutaneous Neuromodulation on the Mean Velocity in Crossfit Practitioners.

This randomized controlled blinded clinical trial aims to evaluate the effect of ultrasound-guided percutaneous neuromodulation (US-guided PNM) targeting the innervation of the transversus abdominis muscle on squat performance in CrossFit practitioners. The transversus abdominis is a deep trunk muscle that contributes to lumbopelvic stability and force transmission during functional and athletic movements. Previous research suggests that improving neuromuscular activation of the trunk musculature may enhance movement efficiency and performance during resistance exercises. Ultrasound-guided percutaneous neuromodulation is a minimally invasive technique that applies electrical stimulation through a needle placed close to a peripheral nerve under ultrasound guidance, with the aim of modulating neuromuscular function. Healthy male and female CrossFit practitioners aged 18 to 60 years, with at least one year of training experience, will participate in the study. Participants will undergo an initial ultrasound assessment of transversus abdominis activation to classify and distribute the sample into groups. In a second session, mean velocity, mean propulsive velocity, and velocity loss during squat performance will be assessed using a linear velocity transducer. Participants will perform 3 sets of 2 repetitions of the squat exercise at 80% of their one-repetition maximum (1RM). Following baseline assessment, participants will be randomly assigned to either an experimental group r…
