Autoregulation, using a perceived recovery scale, did not enhance muscle size or strength gains in trained men over a 10-week periodized resistance training program. The autoregulated mixed session periodized (AMSP) program increased training volume but yielded similar results to the standard MSP program.
Area of Science:
- Sports Science
- Exercise Physiology
- Strength and Conditioning
Background:
- Periodization is crucial for optimizing resistance training outcomes.
- Autoregulation, adjusting training based on readiness, is proposed to enhance adaptations.
- Mixed session periodization (MSP) incorporates varied training stimuli within sessions.
Purpose of the Study:
- To investigate the impact of autoregulation on training volume, performance, and muscle hypertrophy within a 10-week MSP resistance training program.
- To compare an autoregulated MSP (AMSP) program with a traditional MSP program in trained men.
- To determine if perceived recovery-based adjustments offer additional benefits over a structured MSP protocol.
Main Methods:
- Twenty-four resistance-trained men were divided into AMSP and MSP groups, training 5 days/week for 10 weeks.
- The AMSP group adjusted training volume based on a perceived recovery scale, while the MSP group followed a predetermined plan.
- Measurements included maximal strength (1RM), power (jump, throw), and muscle thickness (ultrasound) pre- and post-intervention.
Main Results:
- The AMSP group achieved significantly higher total training volume (p < 0.001) but similar average session loads compared to the MSP group.
- No significant differences were observed between groups in muscle thickness (upper and lower body), lean body mass, maximal strength, or power.
- Autoregulation did not lead to superior improvements in muscle size or performance metrics.
Conclusions:
- A perceived recovery-based autoregulation approach within an MSP resistance training program does not provide additional benefits for muscle size or performance in trained men.
- The findings suggest that traditional periodized programs may be sufficient for optimizing adaptations in this population.
- Further research could explore different autoregulation methods or training populations to clarify its role in resistance training.
