Maybe
@otisbean and
@CloakNNNdagger can collaborate on a case study. Fuller would be an interesting case study.
Also, with your experiences, Fuller came back against the Titans and played 94% of the snaps. Why wouldn't the team or medical staff watch his workload? What are your thoughts on the NBA's "load management" process for Fuller?
That would be interesting. They should have tracked Fuller during the game. The tricky thing with a "groin" injury is that it's a blanket term to cover several muscle groups, such as the adductors and hip flexors. Without knowing which one he injured it would be tough to speculate on how/why he got hurt. He may have been unlucky on a play (meaning anyone could've been injured on that same play) or it could be directly related to his previous injuries. Doc could better explain this.
Load management is smart and all teams should be doing it and I bet most do it to a certain extent. I think you hear about it in the NBA because it's strenuous game and it has a long season with a lot of travel (travel is stressful to the body). When you hear load management, you have to realize stress is stress to the body. A hard practice or game stresses the body just like a fight with your wife/girlfriend does. There are devices available now that do a good job of giving insight into what's going on behind the scenes in your body, namely your autonomic nervous system. The ANS has two branches, the SNS, which is the stress side of the coin - also known as your fight or flight response, and the PNS, which is the rest and digest side of the coin. When training athletes there are two scales you have to pay attention to, their "preparedness" and their "readiness". Both of these are tied to the autonomic nervous system.
Preparedness is just like it sounds, how prepared is the athlete to handle a particular workload and it's developed through the training/workout/practice process. You wouldn't take a newbie through a professional athletes workout, you'd break them as they aren't physically prepared to handle the stresses of that style of work. However, if you built them up over the course of a year or two, they could handle really tough workouts without breaking down because you've prepared their bodies to handle the workload.
The second scale is their "readiness", and this is where load management comes into play. The readiness scale looks at how ready the athlete is to perform on a given day. Let's say we took a pair of identical twins that play for the same team in the NFL. Both have essentially the same genetics and are trained/coached the exact same way so their preparedness is essentially the same. Twin A is a laid back dude that rarely drinks or parties, makes sure he gets 8-9 hrs of sleep every night, eats really well and has very low levels of stress in his life outside football. Twin B is a partier, eats fast food every day, sleeps 4-6 hrs a night and has a girlfriend that he fights with constantly. This guys body would be under a tremendous amount of stress as he's a professional athlete and he would be completely under-recovered from his work load given his stressful life style. As a coach, I would expect twin A to be a consistent reliable performer that should remain relatively healthy throughout the season. Twin B would be inconsistent and would probably have his fair shares of injuries as he's not allowing his body to properly rest, recover and regenerate during his off time because of his stressful lifestyle.
Think of an athlete like a 5 gallon bucket, they can handle 5 gallons of work before they over flow. Over flow in our example would be over training. The harder the practice/workout/game is the more water gets poured into your bucket. When you sleep, eat well, and do things to enhance recovery, you are essentially emptying your bucket so you're ready to perform the next day. In our example, twin A would show up to practices and games with an empty bucket, meaning he is ready to get after it with 100% effort. Twin B would show up to practices and games with 2-3 gallons already in his bucket so he's not ready to handle his 100% work load, as it would over flow his bucket. It doesn't mean he cannot perform the same amount of work as twin A or even perform as well as twin A, it means that his body would be paying a higher cost for that performance and thus generate higher levels of fatigue and have a higher risk for injury. If this happened every now and then it might not be a big deal, but if it happened consistently twin B would have issues.
Tying this back to Fuller, an injury would reduce preparedness and readiness. The injured tissue cannot handle the same stresses that healthy tissue can. Additionally as you are allowing the injured tissue to heal, other muscles can become de-conditioned as they aren't exposed to the same levels of stress on a consistent basis, and they can be prone to injury if you don't adjust the workloads to a level they can handle when they resume normal work. In his first game back, Fuller might have a 3 or 4 gallon bucket to work with so ideally you'd need to adjust his work load to a level that would fit in his current bucket.
Tying this back to Doc's point on genetics, some guys are 3 gallon bucket guys. They may be genetically predisposed to only be able to handle so much work. Through the training process, every one can improve. The 3 gallon guy might turn into a 4 gallon guy, but he might never develop into a 5-6 gallon guy.
Hopefully this all makes sense and gives a basic explanation of load management. I also hope I didn't bore anyone to tears.
