Performance versus moment of inertia of sporting implements (p 7-15)
Rod Cross, Alan M. Nathan
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.88

	This study dispels the popular notion that a heavy sporting instrument is more powerful than a light one. Instead, it is shown that both the intrinsic power and the swing speed are closely related to the moment of inertia of the instrument about the handle. Examples are given from tennis, baseball, and golf. © 2009 John Wiley and Sons Asia Pte Ltd

Biomechanical analysis in freestyle snowboarding: application of a full-body inertial measurement system and a bilateral insole measurement system (p 17-23)
Andreas Krüger, Jürgen Edelmann-Nusser
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.89

	Understanding the biomechanics in snowboarding is essential to prevent equipment-related injuries. The combined usage of an inertial measurement suit and an insole measurement system, as presented in this paper, can provide useful information to better understand this. © 2009 John Wiley and Sons Asia Pte Ltd

Mechanics of flight in ski jumping: aerodynamic stability in pitch (p 24-31)
Pascual Marqués-Bruna, Paul Grimshaw
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.84

	In this study, we use computer-aided design and mathematical modelling to determine enhanced posture in ski jumping, which represents a compromise between maximum aerodynamic efficiency and utmost flight stability. Mechanisms of aerodynamic stability in pitch are suggested, founded upon theoretical aerodynamics. © 2009 John Wiley and Sons Asia Pte Ltd

A new measuring technique for determining the forces acting on the pulley system of the finger (p 32-38)
Isabelle Schöffl, Konrad Oppelt, Andreas Schweizer, Arnika Hugel, Jörg Jüngert, Friedrich Hennig, Winfried Neuhuber, Volker Schöffl
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.86

	A method is presented for determining forces in restrained places as underneath the pulleys of the finger. This allows a comparison of a physiological loading with biomechanical models for the first time and finally enables us to evaluate the forces causing pulley ruptures, the most frequent injuries in sports climbing. © 2009 John Wiley and Sons Asia Pte Ltd

Bowler analysis in cricket using centre of mass inertial monitoring (p 39-42)
David Rowlands, Daniel Arthur James, David Thiel
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.87

	Incorrect bowling action in cricket can result in poor performance and injury. This paper shows that inertial sensors placed at the sacrum give clear signals which can be interpreted in terms of run-up speed, step length, and hip rotation. © 2009 John Wiley and Sons Asia Pte Ltd

Development of a real-time performance measurement and feedback system for alpine skiers (p 43-52)
Richard Kirby
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.85

	With the difference between places in alpine ski racing coming down to one-100th of a second, teams are looking to new high-tech methods to train Alpine racers. This paper explores the development of a real-time feedback system for training alpine ski racers. © 2009 John Wiley and Sons Asia Pte Ltd

Streamlining the time trial apparel of cyclists: the Nike Swift Spin project (p 53-60)
Len Brownlie, Chester Kyle, Jorge Carbo, Nate Demarest, Edward Harber, Richard MacDonald, Matt Nordstrom
Published Online: Sep 2 2009 11:46PM
DOI: 10.1002/jst.12

	Can a cyclist's choice of time trial suit determine whether he wins or loses the Tour de France or sets a world record? We describe how wind tunnel research helps reduce a cyclist's aerodynamic drag to make every second count. © 2009 John Wiley and Sons Asia Pte Ltd
