The qualitative analysis of tennis strokes is a demanding task because of the complexity, speed, and dynamic nature of most tennis strokes. Coaches are likely to be more effective if they integrate information from all the sport sciences using a comprehensive model of the qualitative analysis process. This model of qualitative analysis (Knudson & Morrison, 1997) is summarized and illustrated for several tennis strokes. Coaches can improve their qualitative analysis of tennis players by focusing on the evaluation of both strengths and weaknesses of performance, diagnosing the causes of poor performance, carefully prescribing a single intervention, and continuing to qualitative analyze the player's performance.
