Then in the early 1980s a New Zealand physical education teacher, Jim Blair, popularised the idea that physical fitness (and fitness testing) be incorporated into the schedules of team sport players, particularly rugby players. Blair worked with the All Blacks and was so successful that at the inaugural rugby World Cup in 1987, which they won, the New Zealand team was considered to be the fittest and best prepared team in the tournament. Nowadays, players from all team sports are used to reporting for physiological testing throughout the year and know that they can ill afford to take too much rest, less they lose their hard-earned fitness. Now there is good scientific evidence to suggest that off-season training may be the most important time to undertake physical fitness training tor team sport players.
