Coaches analyze various technical, tactical, behavioral, and physical aspects of performance. Technical analysis examines movement efficiency and mechanics compared to a perfect model. Tactical analysis assesses decision making and game strategies. Behavioral analysis observes psychology and mental states. Physical analysis measures attributes like speed, strength, and endurance. Coaches use methods like notation, video review, and statistical analysis to evaluate performance and provide feedback to enhance future results.
