In college, women’s hockey players are reporting concussions at a higher rate than male hockey players. In fact, female hockey players are reporting a higher concussion rate than nearly all sports sanctioned by the National Collegiate Athletic Association (NCAA). In several studies, female hockey players have reported concussions more often than men’s college football, and at a rate that is comparable to men’s college wrestling and men’s college ice hockey.

Compared to sports like women’s tennis or women’s basketball, hockey is faster, played on harder surfaces, and involves more collisions, which partly explains the high rate of concussions but doesn’t account for the fact that female athletes are reporting more concussions than male athletes who also play hockey. In fact, several surveys have demonstrated that, besides hockey, female athletes consistently report a higher concussion rate than male athletes playing the same gender comparable sport (e.g basketball, soccer, softball/baseball).

The reasons why are unclear, but this video highlights some of the plausible factors, including: gender bias, reporting bias, differences in style of play (for example, body checking is allowed in men’s hockey and is illegal in women’s hockey), hormonal differences (progesterone is of particular interest to researchers), neck strength, and differences in the structure of nerve fibers called axons.

To help understand how these factors might influence the concussion rates, this video features interviews with University of North Carolina researcher Zachary Kerr and retired US Women’s Hockey player Josephine Pucci, who ended her career following several concussions. To hear her story of how she came back to win a 2014 Olympic Silver Medal while playing on the Harvard Women’s team, make sure to watch the video above.

A note on the data: Many of you have noticed that the survey cited at 0:24 contradicts the fact that female athletes report concussions at a higher rate than men playing a comparable sport. However, despite that data point, the general understanding, established through many years of study by different researchers using a variety of methods, is that women do report higher rates of concussion. Although I wasn't able to squeeze all the data in the video, I've listed several sources in the description above. If you'd like to learn more, make sure to check them out. Thanks for watching! -Mac

When I get hit hard, most of the time I try to get up.
And when I’m hurt and my bone is broken( hands), I’m still getting up, and I’m still trying to play
But a scratch got nothing on me, but if my left foot is broken and I can’t walk, I’m going to stay down

I feel like whenever you talk about women at all people screw off their heads and start yelling generally hateful and baseless things and then don't understand why women have to fight for equality still.

People love the idea of the reporting distinction because its nebulous and undefinable. The reality is that rules are set up in modern NCAA sports and have been for a decade and more now that prohibitively force men to be checked for concussions after high impact plays, and a lot more technology has been introduced to monitor impact. So appealing to what amounts to a stereotype that is from a different time is not particularly helpful.

I feel it’s not just reporting it. I’ve been playing hockey for a while and going against a girls team is tough. Not in a bad way but they are vicious and definitely a challenge to play against.

Not having checking in women's hockey just seems super sexist to me, it's like the arguments against women's ski jumping the Olympics used to make.

1. women's skulls are not as thick as men's.
2. who knew smashing your head into solid ice would hurt so much, even with a helmet on.
3. comparing a sport played on solid ice, to astro turf.

I think she solved it herself...Male hockey players are conditioned since teenage years to handle hits, thus their neck strength is stronger and they're used to taking an impact. In I think 2012 percy harvin (american football player) couldnt play for 6 months because of a hamstring injury, and the first game he played was concussed with a tackle that wasn't that scary.

I play AAA hockey and I feel like I’ve had concussions before but I don’t say anything. Why? You’re coach won’t play you as much, in some cases parents pull the plug. Also on my team players joke about concussions so to me I think it’s the fact that males don’t want to look weak.

I think with the men they (unfairly, and unfortunately) are paid more in athletics so they feel they have more to lose. While women only get a small fraction compared to the salary of a male athlete so they might not see the salary as worth risking their health

Men just less likely to admit they got hit that hard hah.

And wtf, they can't check in woman's hockey? That's a major major part of the game..

That’s just because 60% of all those others sports we wouldn’t risk missing playing time by reporting it. Not saying it’s makes you tough or smart but it’s true

Our bodies are built much differently. Men's bodies were for the abuse of hunting and gathering, women's were for maintaining camp. I'm not saying this to be a mysoginyst, it's just how we evolved. Men's bodies have extra "padding" to fight animals or each other, parts of men's brains don't work the same and can sustain more damage without as much displayed outwardly. I was also going to jump to checking when you brought it up. Males players use the boards to watch for hits too, it's just what you do is watch your own back on the boards. So many factors, such a fascinating study...

Sports are a normal thing we play to have fun and, it encourages competitiveness which makes us try to better our selves to attempt to be better than the other. In almost any sport you play injuries happen. What are we supposed to do live in a cocoon the rest of our lives because we may hurt ourselves, that's ridiculous.
