We know that you will find the system to be a fun and motivating tool to help you increase your tennis skills. In this manual, you will find information to help you take full advantage of what Acurasee has to offer. Happy hitting! TABLE OF CONTENTS Development of the Acurasee SyStem The Acurasee System was developed by an experienced tennis coach whose goal was to produce a practical and effective tennis training tool. This coach assembled an advisory group consisting of a nationally ranked player, experienced coaches, a sports psychologist and a professional knowledgeable in the area of training psychomotor skills. From this group came the guiding principles for the development of Acurasee: The training device should: • Provide immediate knowledge of results (feedback) • Provide for positive, interesting activities that motivate the player to improve • Provide players and coaches with a convenient method to provide repetitive practice of specific skills • Provide enhanced feedback that communicates shot accuracy with precision and objectivity • Provide a feedback system that rewards accuracy in any direction around a specific target spot • Provide coaches and players with an efficient method to obtain a precise, accurate and reliable summary of improvement across repeated practice sessions A lengthy period of field-testing and product modification led to continual improvements in the Acurasee System. The final version, either the Circular Target or the Rectangular Target, with electronic feedback and automatic point scoring, is the training device you have purchased. 3 INTRODUCTION of the Acurasee System The Acurasee System for training tennis players focuses on the single most important aspect of a tennis shot – LOCATION. While other attributes of a shot – such as speed (pace) and spin are important, where the ball lands on the court is the most important feature of the shot. Scientific research with the Acurasee System has empirically demonstrated its effectiveness as a training tool. Use of the Acurasee System in controlled research has shown it to be superior to typical training methods in improving the location of shots including: • Depth of all types of ground strokes • Hitting baseline corners • Hitting short angle shots • Down the line shots • Drop shots • Serves The Acurasee System achieves superior results as a training tool because it maximizes the effectiveness of the three major factors known to enhance the acquisition of psychomotor skills. These three factors... ➊ feedback, ➋ motivation and ➌ number of practice trials – are heightened whenever the Acurasee System is employed. ➊ Feedback Fast and accurate feedback is an essential component for learning any complex psychomotor skill. When feedback is delayed – or even worse, inaccurate – the value of a learning trial is diminished. The enormous value of immediate, accurate feedback was a major driving principle that led to the development of Acurasee. ➋ Motivation Research demonstrates that the acquisition of motor skills is accelerated when the participants are interested, focused and eager to improve their skill. This complex of variables – motivation – is essential to acquiring new skills. The relationship of motivation to skill acquisition can be represented by the relationship: SKILL ACQUISITION = PRACTICE TRIALS x MOTIVATION x ACCURATE FEEDBACK. ➌ Practice Trials Research and clinical experience has demonstrated that the key to excellence in any activity is practice. Even the most naturally gifted athletes must practice diligently to achieve mastery of their skills. Tennis, perhaps even more than most other sports, demands extraordinary amounts of practice in order for participants to achieve high levels of skill. The Acurasee System was specifically designed to provide fast and accurate feedback regarding ball placement (location). The target design, with lights and sounds as feedback for accurate shots, serves to motivate the player to achieve positive results with each shot. Players find the feedback to be rewarding (reinforcing their behavior) and therefore are willing to engage in long stretches of motivated practice. By creating an accurate positive feedback system the Acurasee system will lead to rapid improvement in your player’s ability to hit specific locations with their shots. PRACTICE DRILLS WITH the Acurasee System If you purchased the Acurasee Circular Target System, please refer to Section A. If you purchased the Acurasee Rectangular Target System, please refer to Section B. SECTION A: Circular target system Use of the Acurasee Circular Target System encourages players and coaches to think about the most important element in tennis – where will the shot hit the court. The Circular Target System encourages players to have a specific shot location in mind whenever they hit a stroke. The Circular Target System is particularly useful to train players in skill areas such as: • Hitting forehands, backhands, and volleys deep in the corners of the court (cross- court or down the line) • Hitting sharp angled shots • Hitting drop shots • Hitting serves to various locations in the service box Since the Acurasee Circular Target is a portable device, the target can be moved to 45 any court location desired. This enables practice in hitting to any specific location on the court. The Circular Target System enhances drills for both players and instructors. Due to the automatic, accurate feedback provided by the circular target system, the coach can focus on how balls are fed and the players’ form in hitting shots. The player can focus on shot production knowing that auto…
