FITTER Genes 🧬: Can Genetics Predict Injuries?

This is one of the most frequently asked questions I get on a weekly basis. I want to start by stating that any sports injury is multifactorial. A contact injury could occur from two people colliding, someone being pushed off balance or a piece of sports equipment hitting a person. Additionally, a non-contact injury can take in to account the preparation of training stress leading up to the injury. Over-training or under-training for your competition can increase the likelihood of an injury.

However, in any instance, genetics play a massive role in injuries. A 2018 article by McCabe and Collins, looked at 289 soccer players and these 4 genes (GDF5, AMPD1, COL5A1, IGF2). The purpose of the paper was to look at genes associated with ankle and knee injuries at various levels of soccer and the effect of games missed due to injury. If you read the paper, you will find that the:

  • TT genotype of GDF5 had an increase in ankle and knee injuries

  • CC genotype of AMPD1 had fewer ankle, knee and total injuries

  • TT genotype of COL5A1 had an increase in total injuries

  • GG genotype of IGF2 had an increase in total injuries

So where do we go from here?

It is vitally important to understand that even if you have one of the genes above, it does NOT mean you are destined for a sport injury. It does mean you now have a blueprint to show you where to focus your time. It is understanding where your low hanging fruit is, which are the areas of focus that give you your biggest bang for your buck. IT IS SAVING YOU TIME! Which will always be the most valuable and precious resource for people.

If an athlete has the TT genotype of the GDF5 gene what would you do? You might include exercises that strengthen the muscles and tendons surrounding the ankle and knee. You might supplement their diet with foods that target the rebuilding of those structures and support recovery specific to their genetic makeup. While injury prediction will always be a hot topic in sports, it is quite clear that understanding an athlete’s genetics is not only valuable, but mandatory as a foundational screening assessment.

Keep reading for a real-world example with one of my athletes:

I worked with a professional soccer player who had one of these “injury” genes. (HINT: most of us have these genes, they are not uncommon). We used their genetics as the first level of evaluation to develop the most accurate program for them. Since we knew they had a gene that is associated with ankle and knee injuries, we then began to look at their previous injury history. In the previous 3 years they had no major ligament injuries and had a few leg injuries (hamstring, calf).

Then we began a testing protocol to determine current athletic status: force plate countermovement jump, VO2 Submax and total body movement screen by the team Physical Therapist. We found the athlete had a great fitness base with a predicted 62 VO2 max (we would further evaluate “fitness” in live-training with the team). They had below average impulse (force x time) from the force plate analysis and less than ideal mobility in their hip and ankle mobility.

The Plan..in 30 seconds or less

The plan was to improve stability and mobility, through strength training, by progressively overloading a hinge and lunge pattern. Additional strength planning would focus around hamstring strength for their positional demands. Further power would be enhanced upon by focused plyometrics in various intensities, planes of movement and volumes. Mobility work pre-training would focus on specific preparation to the upcoming training session (hamstring v calf complex, etc). We would attack horizontal force capacity via on-field sprint training and high speed running exposure. So much can go into performance planning for an individual, but it all starts with the right data, the genetic data.

💪 FITTER Workout 💪

I was speaking with a friend the other day who said they dropped the ball on their 2024 Goals and had no idea where to start their fitness goals. I told him to check in the FITTER HUMANS today so everyone could check out simple, yet effective starting strength plan. It’s a 2 circuit program that can be completed in 15 minutes. All exercises are linked to my Youtube page.
