Athlete performance is tracked through various metrics during a sports season, including statistics like points scored, assists, turnovers, and time spent in play. Coaches often employ video analysis to assess performance and identify areas for improvement. Wearable technology, such as GPS trackers and heart rate monitors, provides additional data on an athlete's efficiency, endurance, and overall fitness levels. Regular evaluations and adjustments based on this data are crucial for optimizing performance and ensuring athletes reach their full potential.
