A proposed model for examining the interference phenomenon between concurrent aerobic and strength training

Area of Science:

• Exercise Physiology
• Sports Science
• Training Adaptations

Background:

• The interference phenomenon describes the potential negative impact of combining aerobic and strength training.
• Current research offers modest support for interference models but lacks systematic investigation.
• Understanding interference is key for optimizing concurrent training programs.

Purpose of the Study:

• To review current research on the interference phenomenon in concurrent training.
• To identify methodological limitations in existing studies.
• To propose guidelines for future research to enhance the validity of interference models.

Main Methods:

• Systematic review of existing literature on concurrent training.
• Analysis of methodological approaches and variable control in previous studies.
• Identification of key factors influencing the interference phenomenon.

Main Results:

• Modest support exists for interference models, but methodological inconsistencies hinder validation.
• Lack of precise training objectives (e.g., hypertrophy vs. neural adaptation) and equated volumes complicates interpretation.
• Overtraining, inadequate recovery, and varied training statuses are significant confounding factors.

Conclusions:

• Future research must employ systematic protocols with clearly defined training objectives and equated volumes.
• Investigating the impact of periodization, gender, training status, and training modes is essential.
• Careful experimental design, including considerations for recovery and regeneration, will improve the understanding of the interference phenomenon.
