Summary
Using a roller massager during resistance training rest periods reduced performance and increased perceived exertion. This self-administered massage intervention may hinder intense training goals.
Area of Science:
- Exercise Physiology
- Sports Science
- Rehabilitation
Background:
- Self-administered roller massager interventions are common in warm-ups and post-workout recovery.
- Practical guidelines for efficient embedded interventions lack clear consensus.
Purpose of the Study:
- To examine the effects of roller massager interventions embedded within resistance training rest periods.
- To assess the impact on quadriceps muscles during recovery.
Main Methods:
- A randomized crossover pilot trial with 14 participants.
- Two resistance training protocols with 10 sets of 10 rest-pause back squats (50% 1RM).
- Intervention: 60s roller massager use during 2-min rest periods vs. passive recovery.
Main Results:
- Roller-massager group showed reduced total workload (-11.6%) and concentric power (-5.1%).
- Increased perceived exertion (p < 0.05) and reduced thigh circumference (muscle swelling) observed.
- Significantly reduced delayed onset of muscle soreness (DOMS) 24-120h post-workout (p < 0.001).
Conclusions:
- Embedded roller massager use during training hinders performance and increases effort perception.
- Such interventions may not be suitable for conditioning periods focused on maximizing training intensity.
