The platinum league (tennis players don't ever stop playing).
It's personal! I won my varsity letter playing for Akron Central High School. It started innocently enough. My best friend was #1 on the tennis team and to keep him company, I volunteered to be manager ... a single task. Through a series of injuries, I was needed to complete the team schedule and contributed in a small way to the city championship. When I returned from the service, 30 months in...
متن کاملModeling Opponent Actions for Table-Tennis Playing Robot
Opponent modeling is a critical mechanism in repeated games. It allows a player to adapt its strategy in order to better respond to the presumed preferences of its opponents. We introduce a modeling technique that adaptively balances safety and exploitability. The opponent’s strategy is modeled with a set of possible strategies that contains the actual one with high probability. The algorithm i...
متن کاملThe influence of different playing surfaces on the biomechanics of a tennis running forehand foot plant.
Research suggests that heightened impacts, altered joint movement patterns, and changes in friction coefficient from the use of artificial surfaces in sport increase the prevalence of overuse injuries. The purposes of this study were to (a) develop procedures to assess a tennis-specific movement, (b) characterize the ground reaction force (GRF) impact phases of the movement, and (c) assess huma...
متن کاملEffects of the playing surface on plantar pressures and potential injuries in tennis.
OBJECTIVES To examine the influence of different playing surfaces on in-shoe loading patterns during tennis-specific movements. METHODS Ten experienced male players performed two types of tennis-specific displacements (serve and volley (SV) and baseline play (BA)) on two different playing surfaces; eg, clay vs Greenset. Maximum and mean force and pressure, contact time, contact area and relat...
متن کاملEffects of the playing surface on plantar pressures during the first serve in tennis.
PURPOSE This study aimed at examining the influence of different playing surfaces on in-shoe loading patterns in each foot (back and front) separately during the first serve in tennis. METHODS Ten competitive tennis players completed randomly five first (ie, flat) serves on two different playing surfaces: clay vs GreenSet. Maximum and mean force, peak and mean pressure, mean area, contact are...
