Take Flight

In the 5th behind the scenes episode of B13 – Ultimatum we said, “Pay special attention to David’s movements at :37 in the video… [it] is… an incredible testament to his athleticism.” We promised to explain this statement, and now we are keeping true to that promise.

Most people see David jump from buildings and awe at his athletic ability. In reality, even the simple things he does are awe inspiring from an athletic perspective. To this day no one has provided an accurate physiological explanation as to how David can do what he does, but simply enough it is through his seemingly inconsequential movements which we can understand and explain it.

What is so incredible about David’s movements at :54 of Episode 5 is his dexterity and range of motion (also shown in his window perched position in :58 of Episode 15). These are signs of the dynamic tension he has achieved in his muscles. Dynamic tension is the perfect state of muscular equilibrium, where every muscle is proportionally strong in correlation to every other muscle in the body. Not having dynamic tension (also known as having a lack of muscular integrity) creates unnecessary tension in the body, and pulls the joints into an improper alignment causing the body to move compensatively and inefficiently. One of the most obvious signs of a lack of muscular integrity is a lack of range of motion. A lack of integrity also commonly manifests itself in aching joints (forget all of the “itis” diagnosis’, it is caused by a lack of muscular integrity). Injuries in Parkour of every kind are almost always the result of a lack of muscular integrity as well.

David’s body has been trained into a perfect functional state characterized by this dynamic tension which is why he is able to do what he does. Most peoples see the big movements David performs, the man power gap at 1:44 in his Et Vous? video, or the massive building to building leap he did at 1:07 in the BBC commercial, and are in awe. But we would argue that far more inspiring are his subtle movements that clue to why he is so capable. You can see it in his abilities to immediately change direction as in his lateral jump at 2:53 in the French News Feature. You can see it in his explosion from a standing position at :47 in the Accrohes Toi video (notice there is absolutely no tension in his body when he jumps). You can see it in his leg movement at 30:19 during his interview at the New Yorker Festival. You can see it in his resilience to absorb shock in his jump over the railings at 1:43 in the Speed Air Man video and when he drops from the overpass later in the video at 2:21. And you can clear your mind of any confusion you have from David’s famous fall on the UCLA campus. The fact that he walked away uninjured was also the result of his perfect muscular integrity.

All of David’s abilities as well as his resistance to injury can be credited to the dynamic tension of his muscles. This analysis of course circles back to present day David where we can verify our claim. Many Tracers train for only a short time and begin suffering from physical aliments. Others train for a long time without aliments, but then are all of sudden seriously injured. Both instances are the result of a lack of muscular integrity. David on the other hand has never been seriously injured. Furthermore he is in his mid 30’s and he is stronger, faster, and more capable than ever. He has no joint pain, no shoulder, knee, or wrist issues, and he continues to perform feats of athleticism that a few decades before would have thought impossible by even the most capable humans. How can David perform such incredible feats of athleticism? Maybe we should not ask how David can do what he does, but rather how we can attain that same dynamic tension that will enable us to follow in his footsteps.
