ACC data shows the peak time for winter sport injuries is in May and relate mostly to netball, basketball, rugby union and rugby league. Claims for football players peak in April.
Last year, there were 5854 concussion-related injury claims across rugby union (3256), football (1258), rugby league (609), basketball (457) and netball (274).
ACC injury prevention leader James Whitaker said everyone has a role in recognising and managing concussion.
“We know that early removal and early access to care reduces recovery time.”
For other injuries, he said a common trend was people go too hard, too soon and end up injured.
“It’s really important to take a step back and think about how you can best prepare yourself for the upcoming season.
“Smart things to focus on include increasing your fitness, refining your skills, and improving your physical condition,” Whitaker said.
