- Description: Despite the health benefits associated with children's sport participation, the occurrence of injury in this context is common. The extent to which sport injuries impact children's ongoing involvement in sport is largely unknown. Surveys have been shown to be useful for collecting children's injury and sport participation data; however, there are currently no published instruments which investigate the impact of injury on children's sport participation. This study describes the processes undertaken to assess the validity of two survey instruments for collecting self-reported information about child cricket and netball related participation, injury history and injury risk perceptions, as well as the reliability of the cricket-specific version. Face and content validity were assessed through expert feedback from primary and secondary level teachers and from representatives of peak sporting bodies for cricket and netball. Test-retest reliability was measured using a sample of 59 child cricketers who completed the survey on two occasions, 3-4 weeks apart. Based on expert feedback relating to face and content validity, modification and/or deletion of some survey items was undertaken. Survey items with low test-retest reliability (κ≤ 0.40) were modified or deleted, items with moderate reliability (κ=0.41-0.60) were modified slightly and items with higher reliability (κ≥ 0.61) were retained, with some undergoing minor modifications. This is the first survey of its kind which has been successfully administered to cricketers aged 10-16 years to collect information about injury risk perceptions and intentions for continued sport participation. Implications for its generalisation to other child sport participants are discussed. © 2010 Sports Medicine Australia.

- Description: The aim of this study was to verify if yo-yo intermittent recovery test (level 2) (yo-yo IR2) score is linked to Australian football (AF) performance through match exercise intensity. Six week prospective study design. Twenty-one data sets were recorded from nine individual players that completed the yo-yo IR2, and played an Australian Football League match in the first five rounds of the 2010 season wearing a global positioning system (GPS) unit. Simple mediation modelling was used to analyse the inter-relationship between yo-yo IR2 score, match exercise intensity and AF performance. Playing position and experience were also incorporated into the model to identify conditional affects. A significant direct relationship was observed between yo-yo IR2 and number of ball disposals (p<0.1) and a significant indirect relationship was observed between yo-yo IR2 and number of ball disposals through distance travelled at high intensity (HIR mmin-1) (p<0.1). Moderation analysis showed that playing position affected the relationship between of yo-yo IR2 and HIR mmin-1 (p<0.1) and HIR mmin-1 and total ball disposals (p<0.1). Playing experience also significantly affected the relationship between HIR mmin-1 and total ball disposals. This study is the first to identify the effects of yo-yo IR2 on total ball disposals through HIR mmin-1 performed during AF matches, and that playing position and playing experience affect these interactions. © 2011 Sports Medicine Australia.
