Wind tunnel measurements of the aerodynamic force coefficients for various balls and conditions are presented. The effects of the larger ball diameter and the role of the ‘fuzz’ elements, especially as related to ball wear, are discussed (Image courtesy of NASA Ames Research Center and Cislunar Aerospace Inc.). © 2008 John Wiley and Sons Asia Pte Ltd

The future of biomechanical research in alpine ski racing is limited only by our imaginations. Fusion Motion Capture, as presented in this paper, and parallel advances in technology can improve athletic performances for sporting events. © 2008 John Wiley and Sons Asia Pte Ltd

This paper studies the key properties of shockpads used as energy absorption layers in artificial turf surfaces. The paper presents initial findings on the properties influencing the performance of such layers in the latest generations of artificial turf structures. © 2008 Taylor & Francis

The use of video in coaching is widespread. In the last decade close integration of video capture and computer technology is leading to new systems for motion description and analysis, and to real time feedback to the coach. © 2008 Taylor & Francis

Inconsistent manufacturing of cricket balls (different core sizes and materials within one specific ball model, yet externally indistinguishable) results in a wide range of ball stiffness, leading to unequal chances for both teams, as softer balls are easier to control. © 2008 John Wiley and Sons Asia Pte Ltd.

Golf ball design and manufacturing involves many facets. These range from complex chemical compounds used in construction to the human factors of feel and perception. We will delve into this issue and share how one company approaches this task. © 2008 John Wiley and Sons Asia Pte Ltd

Market research shows that snowboarding is one of the fastest growing sports in the world today, with an estimated 3.4 million boarders on the slopes annually. Based on comprehensive market research and benchmarking analysis this article identifies innovation opportunities and preferred design features for modern snowboards across different riding styles. The research determined stiffness distribution and camber design as key characteristics influencing the “feel” and performance of snowboards for both freestyle and freeride styles. © 2008 John Wiley and Sons Asia Pte Ltd

This article defines propulsion impulse as a measure of ease of running. This parameter can be used effectively in the design of high performance running shoes. In order to predict the propulsion impulse, a sole stiffness prediction method based on eigen-vibration analysis is introduced in this article with a practical design example involving Asics high speed running shoes. © 2008 John Wiley and Sons Asia Pte Ltd
