Abstract: It has been suggested that Percutaneous Electrical Nerve Stimulation (PENS) can increase
muscle strength. No previous study has investigated changes in performance in semiprofessional
soccer players. This study compares the effects of adding two sessions of PENS to a training
program versus the single training program over sport performance attributes (e.g., jump height
and squat speed) in healthy soccer players. A cluster-randomized controlled trial was conducted on
twenty-three semiprofessional soccer players who were randomized into an experimental (PENS
+ training program) or control (single training program) group. The training program consisted
of endurance and strength exercises separated by 15-min recovery period, three times/week. The
experimental group received two single sessions of PENS one-week apart. Flight time and vertical
jump height during the countermovement jump and squat performance speed were assessed before
and after each session, and 30 days after the last session. Male soccer players receiving the PENS
intervention before the training session experienced greater increases in the flight time, and therefore,
in vertical jump height, after both sessions, but not one month after than those who did not receive
the PENS intervention (F = 4.289, p = 0.003, η 2 p: 0.170). Similarly, soccer players receiving the PENS
intervention experienced a greater increase in the squat performance speed after the second session,
but not after the first session or one month after (F = 7.947, p < 0.001, η 2 p: 0.275). Adding two
sessions of ultrasound-guided PENS before a training strength program improves countermovement
jump and squat performance speed in soccer players.
