Training approaches in professional baseball are deeply rooted in tradition, culture, and experience, resulting in resistance to change despite the growing influence of technology. These approaches still rely on outdated motor control theories, neglecting the significance of the environment in favor of internal control processes. The predominant focus of training is on exercises aimed at internalizing "ideal" movement models, disregarding the development of functional perception-action coupling required in dynamic performance settings. Unfortunately, organizations often overlook skill acquisition, a central aspect of professional baseball, highlighting the need for coaches in high-performance environments to reconsider their understanding of learning and the implications of coaching.As organizations allocate more resources to player development and individual athlete preparation, it becomes crucial to integrate the efforts of coaches and support staff effectively. This integration can be achieved by establishing a methodology department incorporating sports science, support staff, and coaching. The department's methodology is based on the principles of ecological dynamics, which provide a framework for the functional design of training and development. By adopting an ecological model of learning and performance, which acknowledges the complexity and variability of dynamic interactions between individuals, environmental and task constraints, the methodology aims to enhance athlete performance through athlete self-regulation in practice. This approach promotes problem-solving skills, engagement with learning constraints, and a better relationship with specific information in competitive environments. The ultimate goal of the methodology department is to implement practice design and interventions that align with the latest insights into the principles underlying skill acquisition, motor learning, and motor control while also educating coaches on these principles.
