In this podcast by Dr. Laby defines deliberate practice as a purposeful, systematic, and focused approach to training with a specific goal and steps, contrasting it with regular practice which is simply repetitive without a specific aim. The key to deliberate practice is feedback, which consists of measurement (metrics to track progress) and coaching (guidance on how to improve). The podcast illustrates this with an example of Dr. Laby's remote work with Trent Alexander-Arnold, where providing scores (measurement) and advice (coaching) led to a significant improvement in his visual concentration and multiple object tracking scores. Ultimately, deliberate practice maximizes the effectiveness of training time and provides the best chance for improvement and success in sports.
