Participants were 5 male rugby union players aged between 21 and 24 years who were all starting players on a team competing in the
National Collegiate Rugby Union Championships. All participants had a minimum of 10 years playing experience.
Five performance behaviors were measured in this study.
Number of ball carries was used to determine the frequency of occasions a player attempted to gain yardage with the ball carried in hand. A successful kick was defined as a kick out of hand from a player with the aim of successfully putting the ball out of the field of play. All matches were videotaped by a trained technician and transferred to computer files on which the frequency of each behavior was calculated using a computerized notation system For each match the number of agreements on the occurrence or nonoccurrence of a response was divided by the number of agreements plus disagreements and multiplied by 100%.
