On average, the researchers found, an average of more than 11 supposed injury events happen in a typical men's game, accounting for more than seven minutes of stopped play. Next, they turned to the women's game.
After analyzing footage of 47 women's games from two tournaments, Rosenbaum and colleagues found a rate of fewer than six supposed injury events in a typical women's game -- a rate of about half of what they saw in the men's games.
Of those claimed injuries, the researchers report this month in the journal Research in Sports Medicine, about 14 percent met the criteria for a definite injury -- meaning that women who do go down are twice as likely to be truly injured compared to men who hit the ground.
"Look how often women pop right back up when they run into someone," Rosenbaum said. "They continue through contact, and we found they are more likely to just keep playing."
The ability to stay on their feet isn't the only feature that separates the women from the men.
Physically, women tend to be smaller. And even for a given body size, their lungs are smaller than men's are, said Andrew Lovering, a respiratory physiologist at the University of Oregon, Eugene.
