Comment on L. Ellis et al. “Estimating cancers attributable to physical inactivity in Australia”
Ellis et al1 claimed that lack of physical exercise increases the risk of thirteen different cancers, and that promoting exercise, if successful, would prevent a proportion of those cancers. These claims have already received uncritical attention in the media#. (Source: Journal of Science and Medicine in Sport)

The impact of wheelchair Rugby classification line-up structure on possession outcome
Objectives. To investigate the impact that the structure and combination of athlete classification within line-ups has on possession outcome in Wheelchair Rugby (WR). Design. Retrospective. Methods. Analysis was conducted using data from all 18 WR matches from the 2020 Tokyo Paralympic Games. Pearson's chi-squared analysis was conducted to investigate the effect of line-up structures on performance and a nested generalised logistic mixed model (GLMM) was fitted to the data to investigate the association between independent variables and the outcome of possessions.

Importance of methodological quality in head injury research + highlighted paper no. 3
This issue ´s main editorial has been written by two of our distinguished Associate Editors who are both highly involved in the clinical care and research of head injuries, Claus Reinsberger and Andrew J. Gardner. Together with the virtual special issue which has already been produced for the SMA Conference 2 023, it illustrates how important JSAMS considers this topic. In many countries, among them Australia with a set of popular collision sports, there is currently a heated debate around proper management of head injuries by medical practitioners and sport organisations/associations.
