The study titled “Should Soccer Players Re-Warm-up at Half-Time? An Exploratory Randomized Controlled Trial in a Professional Women’s Team” investigates the effectiveness of a brief, 3-minute re-warm-up protocol in maintaining performance for the second half of a soccer match.

Study Overview

• Participants: 22 professional female soccer players from Portuguese First and Second Division clubs.
• Intervention: The experimental group performed an Integrated Re-warm-up Soccer (IRW-Soccer) protocol during the final 3 minutes of half-time.+4
• Protocol Components:
  • FIFA 11+ Power Exercises: Six specific exercises (e.g., squats with toe raises, walking lunges, box jumps).
  • Small-Sided Game (SSG): A 5v5 game on a 15x15m field with a two-touch restriction.
• Comparison: A control group that underwent passive rest (rehydration and tactical briefings only).

Key Findings

• Sprint Performance: The re-warm-up group showed a significantly greater improvement in 20-meter sprint times compared to the control group (G2: -0.40s vs. G1: -0.25s).
• Jump Performance: While both groups saw a decrease in countermovement jump (CMJ) height due to fatigue, the decline was less pronounced in the re-warm-up group (G1: -2.85cm vs. G2: -1.82cm).
• Practicality: The study highlights that a 3-minute protocol is more feasible than typical 6-7 minute scientific protocols, fitting into the actual time available after tactical talks.

Conclusions & Recommendations

The researchers concluded that a time-efficient, 3-minute active re-warm-up can enhance sprint performance and mitigate the loss of explosive power in female athletes. They even suggest that FIFA regulations should consider a formal 3-minute on-field re-warm-up period to prioritize player welfare and injury prevention.

To frame the findings of the Abreu et al. (2026) study within the broader scientific context, it is helpful to look at how recent research (2024–2026) views the “half-time challenge.”

The current consensus is that the traditional 15-minute passive rest period creates a “physiological slump” that teams can no longer afford in the modern, high-intensity game. Below are key sources and concepts that frame this re-warm-up (RWU) strategy:

The “Three-Minute” Efficiency Trend

Recent studies have shifted away from long 7–10 minute protocols toward “micro-interventions” that fit real-world coaching constraints.

• Christaras et al.: Found that a brief 3-minute RWU was sufficient to maintain core temperature and preserve high-intensity performance in jumping and sprinting. This directly supports the 3-minute timeframe used in the paper you provided.
• High-Intensity Bursts: A narrative review identified that even 1 minute of high-intensity exercise (at ~90% VO2max) can prevent the performance declines typically seen after a passive break by rapidly re-engaging neuromuscular pathways.

Physiological Drivers: Temperature and PAPE

The findings in the Abreu paper (improved sprint, mitigated jump loss) are grounded in two primary physiological mechanisms highlighted in recent literature:

• Muscle Temperature (Tm): Research updated in 2024/2025 (e.g., Mohr & Krustrup) emphasizes that Tm can drop by 1.5°C to 2°C during a passive half-time. This cooling directly reduces nerve conduction velocity and muscle contractility. The Abreu study’s RWU acts as a “thermal bridge” to keep Tm near performance-optimal levels (approx. 39°C)
• Post-Activation Performance Enhancement (PAPE): A 2025 pilot trial in professional women’s soccer explored PAPE-based re-warm-ups. It suggests that strength and plyometric-based exercises (like the FIFA 11+ Power exercises used in your paper) “prime” the central nervous system, allowing for faster motor unit recruitment at the start of the second half.

Contextualizing Female-Specific Findings

While most historical data is based on male athletes, 2025–2026 has seen a surge in female-specific sports science:

• Neuromuscular Control: Recent comparisons between the FIFA 11+ and other protocols (like HarmoKnee) in 2025 show that FIFA 11+ is superior for female athletes because it specifically targets core and dynamic knee stabilization. In the Abreu study, using these exercises at half-time likely provided a “neuro-protective” effect as well as a performance boost.
• Readiness Monitoring: Studies published use the Acute Readiness Monitoring Scale (ARMS) to show that active re-warm-ups significantly improve a player’s perceived readiness, which correlates with more aggressive high-intensity running in the first 15 minutes of the second half.

4. Strategic Impact on Match Play

• Tactical Advantage: Research from February 2026 (ResearchGate) indicates that teams using an active RWU often show higher ball possession and less defensive high-intensity running in the first 15 minutes of the second half. This suggests that “ready” players can dictate the game’s pace, forcing the opposition (who may be “cold”) to react.
• Injury Prevention: The reduction in CMJ height loss found in the Abreu paper (G1: -2.85cm vs. G2: -1.82cm) is a critical marker. Recent 2025 data links the loss of vertical jump height to increased neuromuscular fatigue, which is a primary risk factor for ACL and hamstring injuries—both of which are more prevalent in professional women’s soccer.

In conclusion: The Abreu et al. paper is at the forefront of a 2026 trend toward ultra-brief, high-specificity re-warm-ups. By framing it with these sources, you can see it is not just about “staying warm,” but about neuromuscular priming and injury risk mitigation specifically tailored for the professional female athlete.
