Why Percussive Massage Therapy Does Not Improve Recovery after a Water Rescue? A Preliminary Study with Lifeguards

Area of Science:

• Sports Medicine
• Exercise Physiology
• Occupational Health

Background:

• Lifeguards face intense physical demands during water rescues.
• Effective recovery strategies are crucial for lifeguard performance and injury prevention.
• Percussive massage therapy (PMT) is increasingly explored for athletic recovery.

Purpose of the Study:

• To evaluate the efficacy of PMT versus passive recovery (PR) for lifeguards post-water rescue.
• To compare physiological and perceptual recovery markers between PMT and PR.

Main Methods:

• A quasi-experimental crossover design involving 14 lifeguards.
• Simulated 100m water rescue followed by an 8-minute recovery period.
• Measurement of blood lactate and perceived fatigue as recovery indicators.

Main Results:

• No significant difference in blood lactate clearance between PMT and PR.
• Both PMT and PR significantly reduced perceived fatigue.
• No significant differences in fatigue reduction were observed between the two recovery methods.

Conclusions:

• Percussive massage therapy does not offer enhanced recovery benefits for lifeguards after a water rescue compared to passive rest.
• Current evidence does not support the recommendation of PMT for this specific occupational group and activity.
• Further research may explore different PMT protocols or recovery scenarios for lifeguards.
