In this episode, Louis discusses movement economy, which refers to the efficiency with which the body uses energy to perform a specific task. He explained that this concept applies to various disciplines, such as running, weightlifting, and Crossfit, and that it is not solely about strength or endurance, but also about neuromuscular coordination and biomechanics. Louis also outlined how movement economy can be assessed through video analysis, heart rate monitoring, force plate testing, and feedback from coaches or clinicians. He emphasized the importance of addressing inefficiencies and imbalances in movement to improve performance and reduce the risk of injury. Finally, he suggested that training for better movement economy should involve technique drills and repetition to focus on the fundamentals.
