This book chapter comprehensively examines the effects of endurance and functional movement-based training approaches on performance. The chapter addresses the adaptations of endurance training on energy systems, the determinants of movement economy, the impact of different training models on performance, and individualized programming strategies. Injury and fatigue management are also evaluated from a performance optimization perspective.

Energy system adaptations can affect both aerobic and anaerobic capacity and support performance sustainability. Movement economy is influenced by biomechanical, musculoskeletal, and neuromuscular factors and can increase energy utilization efficiency. Different training models and individualized programming strategies can optimize an athlete's metabolic and mechanical capacity. Finally, injury and fatigue management plays a critical role in performance sustainability.
