In the lead article in this month's sport and exercise medicine section Raysmith and Drew report on the impact of injury and illness on training availability of track and field athletes. They indicate that training availability is a critical determinant of performance goal success or failure at the international level. In the second article in this section Drew and co-workers report that the prevalence of groin pain in Australian Football players warrants assessment of mechanical pain sensitivity in this group. Hebert's group reviewed the literature relating to second impact syndrome and concluded that currently there is not enough evidence to support a standardised WHO case definition. In the final paper in this section Gordon and colleagues, in a report of a randomised cross over trial, suggest that type of exercise does not affect the glycaemic response in individuals with type 2 diabetes.
