Short-duration passive half-time interventions (percussive therapy, electrical muscle stimulation, and pneumatic compression) can mitigate performance decline in adolescent soccer players, with percussive therapy and EMS most effective for technical skills and pneumatic compression supporting perceived recovery.
Key Findings
Results
Passive rest during half-time led to significant deterioration in technical skill, sprint performance, and perceived recovery in the control group.
Forty-three academy-level male soccer players (17.5 ± 0.6 years) participated in the study.
Participants were randomized into one of four 15-minute half-time intervention groups: Passive Rest (CON), Percussive Therapy (TG), EMS (PD), and Pneumatic Compression (COMP).
Performance deterioration in the control group was statistically significant (p < .05) across technical skill, sprint performance, and perceived recovery outcomes.
Linear mixed-effects models were used to assess Time × Condition interactions for all performance and recovery outcomes.
Results
Percussive therapy (Theragun Pro) and electrical muscle stimulation (PowerDot) significantly improved technical performance compared to the passive rest control group.
Technical performance was measured using the Loughborough Soccer Pass Test (LSPT).
Both TG and PD showed significant improvements in LSPT scores compared to the control group (p < .01).
Effect sizes were moderate: d = 0.65 for TG and d = 0.72 for PD.
These two interventions were described as 'most effective for preserving technical skills.'
Results
Percussive therapy and pneumatic compression were effective at maintaining 20-meter sprint times, while the control group experienced significant slowing.
Sprint performance was assessed using repeated 20-meter sprints.
Both TG and COMP maintained sprint times at statistically significant levels compared to control (p < .01).
Effect sizes were d = 0.58 for TG and d = 0.49 for COMP.
The EMS (PD) group was not identified as significantly effective for sprint maintenance, distinguishing it from TG and COMP on this measure.
Results
Perceived recovery scores declined significantly in the control group during half-time, but this decline was significantly attenuated in all three intervention groups.
Perceived recovery was measured using Total Quality of Recovery (TQR) assessments before and after half-time.
CON group TQR scores declined from 16.5 ± 2.2 (First Half) to 11.1 ± 2.3 (Second Half).
TG group declined from 17.5 ± 1.9 to 14.2 ± 1.9; PD group from 17.3 ± 1.9 to 15.1 ± 1.9; COMP group from 17.6 ± 1.9 to 15.9 ± 2.0.
All three intervention groups showed significantly attenuated declines in TQR compared to the control group.
Methods
The study used a simulated soccer protocol to evaluate half-time intervention effects on second-half performance in elite youth academy players.
The protocol included the Loughborough Soccer Pass Test (LSPT), repeated 20-meter sprints, and TQR assessments.
The half-time interval lasted 15 minutes, during which interventions were applied.
Participants were 43 academy-level male adolescent soccer players aged 17.5 ± 0.6 years.
The study described percussive therapy, EMS, and pneumatic compression as 'technology-based, passive recovery modalities' requiring 'minimal active movement or physical exertion from the athlete.'
Results
Pneumatic compression was highlighted as particularly supportive of perceived recovery among the passive interventions tested.
COMP group had the smallest TQR decline of the three intervention groups, from 17.6 ± 1.9 to 15.9 ± 2.0.
The authors specifically noted that 'COMP may support perceived recovery' in their summary of findings.
COMP was effective for sprint maintenance (d = 0.49, p < .01) but was not identified among the top performers for technical skill improvement.
All intervention devices used were commercial products: RecoveryAir for COMP, Theragun Pro for TG, and PowerDot for PD.
What This Means
This research suggests that the 15-minute half-time break in soccer, if spent in passive rest, causes measurable declines in players' sprinting ability, passing accuracy, and how recovered they feel heading into the second half. To test whether simple, low-effort recovery devices could prevent this decline, researchers had 43 elite youth soccer players (average age 17.5 years) use one of three devices during half-time — a percussive massage gun (Theragun), an electrical muscle stimulation device (PowerDot), or pneumatic compression boots (RecoveryAir) — or simply rest passively as a comparison group. All three devices outperformed passive rest on at least one measure of recovery or performance.
Specifically, the massage gun and electrical stimulation device were best at preserving passing accuracy and technical skill, while the massage gun and pneumatic compression boots were most effective at preventing a slowdown in sprint speed. All three interventions also helped players feel more recovered heading into the second half compared to those who just rested, with pneumatic compression showing the largest benefit for perceived recovery. Effect sizes were moderate across measures, suggesting practically meaningful — not just statistically significant — differences.
This research suggests that passive, technology-based recovery tools applied during half-time could be a practical addition to soccer teams' in-game strategies, particularly for youth academy players. Since these devices require little effort from athletes, they could be used alongside or instead of active re-warm-up protocols, offering coaches and sports medicine staff more flexible options for managing player performance across a full match.
