Turf ACL injuries that I’ve seen don’t involve contact, meaning the person tears their acl without being touched. I would look at each injury and see if more ACLs are torn without contact on turf or grass. Nobody touched Odell he just got hurt running on the turf

Most of the injuries are non-contact - for both grass and turf - especially if you use the classification of 'contact' being a direct blow to the lower body. A number of the injuries are involved when players are engaged (blocking scenarios) and the leg simply gives out. Even though there is 'contact' it is not officially a contact injury, and should be classified as non-contact. There is a lot of grey area here with the classifications, and this information is not always released when the injury is announced. I tend to find video of the actual injury about 70% of the time through replays, social media posts, etc. But the injury is rarely published in the media with all of the details. Teams tend to keep this information close to their vest, especially when they happen in practice or training camp, and can't be viewed in broadcast games. From the data I've collected, the non-contact injuries are evenly split on grass vs turf within 2% to 5% variability from season to season in last 5 years.

Good comparison on fields themselves, especially after this Rodgers injury. I think it comes down to body movement adjustment, especially when you play on different fields for different games. It's physical it happens🤷🏼♂️

What I fear most is that people will lobby for grass fields only, and then find out the injury totals haven't changed at all. If we gave the teams longer periods of time in the off-season to train athletes consistently, many of these injury totals could be reduced significantly.

I think you make the key point that these high level players play on so many different surfaces. It would be interesting to look at the NHL and ice quality differences, although it can vary from night tonight. The NBA and the court quality and MLB where every ballpark is different. That would be a tough analysis but with AI maybe someone can do it. It would be fascinating.

@@steveo3831 Very true. I think it goes back to an athletes off-season training and how well it prepares them for the environments and surfaces they will encounter. If you have a robust training program, you will naturally be more adaptable when new scenarios are encountered.

The injury rate between Grass and Turf are pretty even. Turf holds up better in cold wether than grass. No stadium field is good enough to avoid injuries forever no matter what kind of field they use. It's a sensless debate. MetLife stadium Turf has been known to hold out well in inclimate wether especially when it hosted the super bowl: Check Out - Packers vs. Giants Week 13 Highlights | NFL 2019 - It held out well in the snow and didn't come close to player injuries. Proof positive some turf fields are better than most skeptics give it credit for.😀

@@EmmanuelConstant747 I would say both the players and the organization/team should be aware of the need to vary up surfaces and prepare appropriately for these various surfaces, working on movement preparation, deceleration, change of direction, etc. and also looking into the appropriateness of different types of footwear, including the cleats they wear.

how they prepare would require a variety of different surfaces during practice. Virtually impossible. Another important look would be non contact ACL injuries during practice and on what surface? It’s a conundrum. This type of research would require every major sports league and team to cooperate. So much of this information would be hidden and not disclosed. Wow. This is a monumental venture. But someone can do it. And it needs to be done. Start from the top down and make sure this information is mandated, held privately.

Good video. But my theory is the Bermuda grass fields are just as dangerous as the artificial/hybrid turf fields ACL wise. I believe Kentucky Bluegrass fields are safer and will yield less non contact ACL tears because it doesn’t have the above ground stolons like Bermuda. Instead it has ryzomes that spread underground and won’t catch a foot as bad as the other types.

Agreed. Someone should aggregate the last 10 or more seasons and code each injury on a bunch of criteria: turf/grass, exact type of surface, what the player usually practices on, maybe shoes and other player-pacific attributes etc. My guess is the effect of surface is going to be overpowered by things like player’s speed, strength, the specific movement triggering the injury, etc (much harder to quantify and analyze). But it’d be worth looking at surface for sure.

As seen in comments below there are some issues with sample size. But I think there are other factor you can’t discount. (1) Is player more likely to suffer injury when playing on a surface that is not the same as his home field surface? (2). Are players more likely to suffer injury in an open air stadium where weather is a large factor versus a dome stadium where climate is controlled. There are many other factors that also need to be considered, such as previous injuries, age, and on and on. To summit up this is not something that can be done in eight minutes on the chalkboard but I do think this is an interesting topic that needs some serious statistical analysis. And this is not limited to a NFL I am an avid fan of women’s soccer and this year alone there has been an unprecedented number of ACL injuries and not just in the United States but internationally. I believe the national women’s soccer league or perhaps US soccer is investigating the cause of a spike in these numbers.

I just found this academic paper that looked at ACL injuries in pro soccer league across 5 seasons. I’m still reading but so far very interring. 2 things I found interesting so far. (1) Training injury rate is higher than match day rates. There is speculation that this could be attributed to quality of training field v stadium field. (2) 37 total players were studied - 18 were contact injuries and 19 were non-contact. I’m still reading it but interesting info. bmjopensem.bmj.com/content/bmjosem/4/1/e000461.full.pdf

As smart as you are why can't you figure out that you must compare the ACL injuries from no artificial turf vs when NFL started to use artificial turf? Your comparison is like comparing DUI numbers around a school at noon vs weekends down town around bars .. we wont ever get our NFL players on a safe field if you keep making the wrong argument .. so for that this is a thumbs down
