Player Perceptions and Biomechanical Responses to Tennis Court Surfaces: the Implications to Technique and Injury Risk
PLAYER PERCEPTIONS AND BIOMECHANICAL RESPONSES TO TENNIS COURT SURFACES: THE IMPLICATIONS TO TECHNIQUE AND INJURY RISK Submitted by Chelsea Starbuck, to the University of Exeter as a thesis for the degree of Doctor of Philosophy in Sport and Health Sciences September 2014 This thesis is available for Library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. (Signature) ……………………………………………………………………………… 1 Abstract Elite tennis players are required to perform on a variety of tennis court surfaces which differ in mechanical characteristics, such as friction and hardness, influencing their performance and risk of injury. To understand the influence of surfaces on performance and injury risk, three studies were conducted to investigate tennis players’ perceptions and biomechanical responses during tennis-specific movements on different court surfaces. In study 1, tennis players perceptions of acrylic and clay courts were identified following a thematic inductive analysis of semi-structured interviews (n = 7) to develop of a series of visual analogue scales (VAS) to quantify perceptions during studies 2 and 3. Perceptions of predictability of the surface and players’ ability to slide and change direction emerged, in addition to anticipated perceptions of grip and hardness. Study 2 aimed to examine the influence of court surfaces and prior clay court experience on perceptions and biomechanical characteristics of tennis-specific skills. -

THE PENNSYLVANIA STATE UNIVERSITY SCHREYER HONORS COLLEGE DEPARTMENT OF FINANCE IDENTIFYING OPTIMAL TENNIS BETTING PORTFOLIOS BASED ON VARYING RISK TOLERANCES OF BETTORS NIMAY GODBOLE SPRING 2020 A thesis submitted in partial fulfillment of the requirements for a baccalaureate degree in Finance with honors in Finance Reviewed and approved* by the following: Dr. Robert Novack Associate Professor of Business Logistics Thesis Supervisor Dr. Brian Davis Clinical Assistant Professor of Finance Honors Adviser * Electronic approvals are on file. i ABSTRACT This thesis assesses the risk versus return relationship in tennis betting among the different tournaments that exist within the Association of Tennis Professionals (ATP) Tour, the main men’s tennis governing body. To do so, betting data is gathered from a website well-known for this data collection, http://www.tennis-data.co.uk/. The purpose of this thesis is to identify optimal betting portfolios for bettors with varying levels of risk aversion. Expected returns and standard deviations of Grand Slam, Masters 1000, ATP 500, and ATP 250 tournaments were analyzed to create an optimal risky portfolio using Markowtiz’s Portfolio Theory. Once that was created, optimal betting portfolios were created by betting a portion of the money in the tennis betting market and investing the rest in Vanguard’s Prime Money Market Fund, VMMXX. The key finding is significant; at a risk aversion level of A = 4, the portfolio yields a return of 11.02 percent and a standard deviation of 15.02 percent, which is a higher return and lower standard deviation than the historical average of the S&P 500. -
Optimal Solutions to Tennis Scoring Systems, Challenge System, Court Surface Allocation and Olympic Games Format
Optimal Solutions to Tennis Scoring Systems, Challenge System, Court Surface Allocation and Olympic Games Format By Tristan Barnett Scoring Systems The fundamental problem with current scoring systems is the deuce game is very “inefficient”. Some games can last for 25 minutes. The 50-40 game where the server has to win 4 points and the receiver has to win 3 points is very “efficient”. At most only 6 points are played in such a game. The number of games played in a set are significantly reduced since there are more breaks of serve. Hence, with the 50-40 game, a ‘long’ advantage final set is highly unlikely. The author has listed all the current scoring systems in table 1 and proposed scoring systems in the second table 2. The author thinks it makes sense to have just the one game structure and the 50-40 game due to its simplicity I feel is best to achieve this goal. All the early sets are tiebreak with a first-to-7 point tiebreak game at 6 games-all. The final set is advantage with a first-to-7 point tiebreak game at 12 games-all. Playing a final advantage set makes sense to keep with tradition. Matches are either 3 or 5 sets. This simplifies the scoring systems to 2. The author published a paper: Barnett T (2012). Analyzing tennis scoring systems: from the origins to today. Journal of Medicine and Science in Tennis 17(2), 68-77. http://strategicgames.com.au/article32.pdf which demonstrates why the deuce game came about and why the 50-40 game could potentially replace it. -
