The Singer-Runner: Endurance Training, Vocal Efficiency, and Evidence-Based Strategies for the Versatile Voice

Abstract: Endurance training can enhance vocal performance by improving breath economy, respiratory coordination, and fatigue resistance, yet it also introduces potential risks such as upper-airway drying, reflux, and exercise-induced laryngeal obstruction (EILO). This article synthesizes peer-reviewed research on hydration, respiratory-muscle training, autonomic load, nasal versus oral breathing, and gastroesophageal considerations in endurance activity. Practical, evidence-based strategies are offered for aligning athletic training with vocal demands through intentional periodization, recovery, and vocal-health planning. A weekly planner and decision framework support the integration of these principles across professional studios and conservatory settings, preserving vocal efficiency while optimizing total performance capacity.
