ABSTRACT
Sports tournaments, particularly events in the racket sports, tend to be distributed throughout the world and over the complete year. This has been encouraged by the growth in televised competitions for professional players and flourishing indoor as well as outdoor tournaments. It is facilitated by the ease of contemporary air-flight which makes it possible to travel quickly from one side of the globe to the other, for example by means of long-haul flights between Europe and Asia or Australia. The potential financial rewards on offer in sports competitions tend to predominate over the biological stress that such itineraries entail.
