Grass vs Field Turf Re. Player Surface Contact Impact

Thought this might interest some of you.

A Popular Mechanics story a couple of years back described how the type of football field surface is measured in terms of shock absorbency by dropping an object the size of a human head and neck (20 square inches and 20 pounds) from 2 feet above the respective surface. The metric is called G-Max.

A low G-Max absorbs more energy than a player. Grass has a G-Max of 60, while synthetic turf has a G-Max of 120. The hardest surface is frozen grass.

Most people associate high g-forces with fighter pilots or astronauts. But few things can match the g-load of a vicious football hit.
 
Didn't want this to get lost in the "random thought" threads, so I guess I'm going to resurrect one of these old field surface threads. With some of the latest reporting that the #1 thing players care about is playing on grass vs artificial turf, I thought this was interesting.

Real Madrid have spent about $1B renovating their stadium, which now includes a grass field removal system. Not sure how much it cost on its own, but it is pretty amazing and is something the Texans should consider. Doubt they will, but...

Wouldn’t that still have creases like our old pallet system did?
 
Of course, player safety is the NFL's priority........ :toropalm:

Jevon Holland makes case for grass over turf
Published November 29, 2023 09:00 PM

The NFL would like you to believe there’s a real debate among players regarding the question of whether they prefer grass or turf.

There is not.

It’s a contrived notion aimed at justifying the cheaper approach to outfitting a field. The owners who have turf don’t want to pay for grass, and the Commissioner who is paid by all of them willingly runs interference.

Meanwhile, specific players continue to make the case for grass, while not a single current player has sung the praises of the fake stuff.

“Turf is tough on the body and being at that place,” Dolphins safety Jevon Holland told #PFTPM, specifically regarding the surface at MetLife Stadium. “I’ve had two of my friends now get injured from that. I just think it needs to be done with, honestly. I think it, you know, they need to really look into it and invest in a better playing surface for their team and teams around the league.”

Indeed they do. Most recently, Dolphins edge rusher Jaelen Phillips had his Achilles tendon rip while pushing out of his two-point stance at the start of a play last Friday.

“Turf is — it’s a hard surface,” Holland added. “There’s no give. Like grass, there’s give and it works with — when you cut, you can feel your cleats sink into the ground. Turf is, it’s like playing on — not playing on asphalt, but it in some terms it is. It’s tough on your joints and your knees and your ankles, and when you hit the ground, there’s no shock absorption to the ground. There’s none of that. But on grass there is. When you fall on the ground, you can roll and you feel like the earth isn’t so hard. That’s the biggest thing for me, honestly. I think that turf is just really tough on the joints and it has a long-lasting effect after practice, after games like, those things start to add up. Playing on grass for me always feels better.”

That’s the common refrain from players. Even if they emerge from a given game on turf without an injury, they feel the overall impact on their bodies of playing on a surface with no give.

Anyone who ever played even two-hand touch on the old green-cement artificial surface knows how it feels to get out of bed the next day. Even with fake stuff that looks less like patio carpet and more like grass, the lack of give means that bodies get banged up a lot worse.

But the league will continue to gloss over that fact, simply because the owners who have turf don’t want to make the investment in a better and safer playing surface.

It would only have 2 or 3 vertical creases vs a checkered board full of them. A similar system has been in place in London at the Tottenham stadium for a couple of years now. I haven't seen or heard of any issues.

For those who might not remember (or ever knew), the NRG grass pallet system involved 5000 seams!..............a knuckle-brain design!:eek:
