A notation system, designed to record rally-end variables in Badminton, was shown to be both valid and reliable. Inter and intra reliability ranged from 98.6% (Rally length) to 91.3% (Position). Percentage differences between data from side, and end observations of the same match were not greater than for the intra-reliability data thus different court viewing angles had little effect on notation. Previous literature declared profiles of performance without adequately tackling the problem of quantifuing of the data required in creating a normative template. The badminton notation system was used to examine the cumulative means of selected variables over a series of 11 matches of a player. A template, at match N(e) was established when these means became stable within set limits of error (LE). Tests on the variable means in games won, and games lost established the existence of winning and losing templates for winners and errors. Match descriptors (rallies, shots and shots per rally) were independent of match outcome. General values of N(e) established for data types, (10% LE), were 3 matches (descriptive variables), 4 (winners/errors (w/e)), 6 (smash + w/e), 7 (position + w/e). Respective values at 5% LE were '7, 5,8 and lO.There was little difference in the values of N(e) when variable means were analysed by game than by match. For the working performance analyst the results provide an estimate of the minimum number of matches to profile an opponent's rally-end play. Whilst the results may be limited to badminton, men's singles and the individual, the methodology of using graphical plots of cumulative means in attempting to establish templates of performance has been served.

Mellens, Lloyd (University of Wales Institute Cardiff, 2011)Research in International rugby union has demonstrated the importance of try scoring (IRB, 2003). Try scoring often determines the result of matches; teams scoring fewer tries only win 16% of matches (Laird and Lorimer, ...
Did set pieces have an effect on the success of teams in the 2011 and 2012 Six Nations Rugby Union tournaments? Sheen de Jesus, Rhiannon (Cardiff Metropolitan University, 2013)The aim of this study was to analyse the effects that set pieces had on possession during the 2011 and 2012 Six Nations tournaments. Thirty matches were analysed, 15 matches from each tournament using an Excel template. ...
