It uses advanced sports-science strategies to assess and train athletes in ways that will revolutionize pro sports \u2013 and, eventually, the bodies and abilities of weekend warriors, Elliott says.<\/p>\n<p>\u201cWe are challenging them and measuring them. But we\u2019re not interested in how high they jump or how fast they accelerate,\u201d Elliott says. \u201cWe\u2019re interested in the mechanics of how they jump, how they accelerate and decelerate. It\u2019s helping us unlock the secrets of human movement.\u201d<\/p>\n<p>Working directly with players and their agents or families, P3 has evaluated members of the past six NBA draft classes, amassing a database of more than 600 current and former NBA athletes.<\/p>\n<p><figure id=\"attachment_29541\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-29541\" src=\"http:\/\/www.sickgaming.net\/blog\/wp-content\/uploads\/2019\/07\/from-predicting-performance-to-preventing-injuries-how-machine-learning-is-unlocking-the-secrets-of-human-movement.jpg\" alt=\"An athlete jumps in a gym, reaching for the ceiling with her right hand. \" width=\"400\" height=\"492\"><figcaption class=\"wp-caption-text\">Volleyball player Cassandra Strickland leaps at P3.<\/figcaption><\/figure>\n<\/p>\n<p>Some of P3\u2019s clients include NBA stars <a href=\"https:\/\/www.basketball-reference.com\/players\/d\/doncilu01.html\" target=\"_blank\" rel=\"noopener noreferrer\">Luka Doncic<\/a> and <a href=\"https:\/\/www.basketball-reference.com\/players\/l\/lavinza01.html\" target=\"_blank\" rel=\"noopener noreferrer\">Zach LaVine<\/a> plus athletes from the NFL, Major League Baseball, international soccer, track and field and more.<\/p>\n<p>Many of those NBA clients, like Philadelphia 76ers guard <a href=\"https:\/\/www.basketball-reference.com\/players\/r\/richajo01.html\" target=\"_blank\" rel=\"noopener noreferrer\">Josh Richardson<\/a>, return to P3 each summer for re-testing to pinpoint whether their movement patterns have gained asymmetries that could cause injury, or to reconfirm the health of physical systems they use to leap, land, stop and start, fueling their on-court edge.<\/p>\n<p>\u201cThis is my fifth off-season now at P3,\u201d Richardson says. \u201cWhen I started with them during my NBA draft preparation, I immediately saw that their approach was different and that it could help me have the best chance to improve my athleticism. Every off-season I get to see exactly where I am physically compared to where I was before \u2013 and compared to other NBA players.<\/p>\n<p>\u201cThey are able to help me identify where I might be at risk of injury and where I can improve physically. It\u2019s important for me to know that the training I am doing is specific to my unique needs,\u201d Richardson says.<\/p>\n<p>To collect all that granular data, P3 outfitted its lab with a high-speed camera system manufactured by <a href=\"http:\/\/www.simi.com\/en\/\" target=\"_blank\" rel=\"noopener noreferrer\">Simi Reality Motion Systems GmbH<\/a>, a German company from the ZF Group and a Microsoft partner.<\/p>\n<p>Simi offers markerless, motion-capture software that removes the need for athletes to wear tracking sensors while they play or train. Simi also works with seven Major League Baseball clubs, deploying high-speed camera systems to those stadiums to record every pitch during every game since the 2017 season.<\/p>\n<p>Simi\u2019s software digitizes the pitchers\u2019 arm angles and related body movements, spanning 42 different joint centers across 24,000 pitches thrown per team per season. That produces hundreds of billions of data points that are uploaded and processed on <a href=\"https:\/\/azure.microsoft.com\/en-us\/\" target=\"_blank\" rel=\"noopener noreferrer\">Microsoft Azure<\/a>, enabling teams to create in-depth biomechanical analyses for the players, says Pascal Russ, Simi\u2019s CEO.<\/p>\n<p><figure id=\"attachment_29530\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-29530\" src=\"http:\/\/www.sickgaming.net\/blog\/wp-content\/uploads\/2019\/07\/from-predicting-performance-to-preventing-injuries-how-machine-learning-is-unlocking-the-secrets-of-human-movement-1.jpg\" alt=\"A laptop screen shows a player in mid-stride on a track and the movement data he is producing.\" width=\"500\" height=\"420\"><figcaption class=\"wp-caption-text\">An athlete\u2019s workout at P3 produces data on his body angles and movements.<\/figcaption><\/figure>\n<\/p>\n<p>\u201cThe first team that deploys this effectively on the field to pick lineups or to see which pitch angles worked well against which batters is going to see a huge separation between them and the other teams not using this,\u201d Russ says.<\/p>\n<p>\u201cIt\u2019s freakishly accurate.\u201d<\/p>\n<p>While Russ foresees this technology eventually remaking baseball, such seismic shifts already are occurring in the NBA through P3\u2019s player assessments, says Benedikt Jocham, Simi\u2019s U.S. chief operations officer.<\/p>\n<p>\u201cWe provide the software solution that can quantify the movement and analyze, for example, how much pressure and torque a person is putting on various body parts,\u201d Jocham says. \u201cP3 adds the magic sauce. They are wizards at figuring out what it all means and making sense out of it for athletes.\u201d<\/p>\n<p>After the cameras record a player\u2019s movements in the P3 lab, those datasets are loaded into Azure where <a href=\"https:\/\/azure.microsoft.com\/en-us\/services\/machine-learning-service\/\" target=\"_blank\" rel=\"noopener noreferrer\">machine-learning<\/a> algorithms reveal how that player\u2019s physical systems are most related to other NBA players who were similarly assessed. The algorithm then assigns that player into one of several clusters or branches that predict how their basketball career may unfold, Elliott says.<\/p>\n<p>One branch, for example, contains athletes who had a brief NBA experience and never became significant players. Another branch encompasses players who were impactful during their first three or four seasons then sustained serious injuries that depleted their skills. In still another branch, players share rare combinations of length, power and force that fed elite careers \u2013 and they remained healthy.<\/p>\n<p>\u201cThe human eye is good at measuring size and maybe estimating weight, and very bad at comparing athletes\u2019 physical systems and movement symmetries to one another,\u201d Elliot says. \u201cBut we can measure those things in the lab and the machine tells us how young athletes are most alike.<\/p>\n<p>\u201cIt\u2019s a solid foothold into an area of sports science that has been out of sight until now,\u201d he says.<\/p>\n<p><figure id=\"attachment_29531\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-29531 size-large\" src=\"http:\/\/www.sickgaming.net\/blog\/wp-content\/uploads\/2019\/07\/from-predicting-performance-to-preventing-injuries-how-machine-learning-is-unlocking-the-secrets-of-human-movement-2.jpg\" alt=\"An athlete looks at a big screen projection of his workout and the data is produced while a coach talks with him.\" width=\"995\" height=\"566\"><figcaption class=\"wp-caption-text\">Cleveland Indians prospect Will Benson scans his workout data with P3 biomechanist Ben Johnson.<\/figcaption><\/figure>\n<\/p>\n<p>The data is also helping to shatter long-held theories that successful NBA players who, at first glance, lack the size, jumping ability or quickness of traditional stars are merely compensating by tapping unmeasurable intangibles such as \u201cintuition\u201d or \u201cIQ\u201d or \u201cheart.\u201d<\/p>\n<p>\u201cThat\u2019s how people once would have defined (2017-18 NBA most valuable player) <a href=\"https:\/\/www.basketball-reference.com\/players\/h\/hardeja01.html\" target=\"_blank\" rel=\"noopener noreferrer\">James Harden<\/a>, as somebody who just has this super-high basketball IQ,\u201d Elliott says. \u201cMaybe he does. But he also has a better stopping or braking system than anybody we\u2019ve ever assessed in the NBA.<\/p>\n<p>\u201cThat creates competitive advantages,\u201d he adds. \u201cThere\u2019s Newtonian physics behind these advantages.\u201d<\/p>\n<p>Case in point: Dallas Mavericks rookie Luka Doncic. In its pre-draft assessment of Doncic one year ago, P3 identified that same hidden performance metric \u2013 the elite ability to stop quickly. P3 knew, before his NBA Draft, that Doncic and Harden were in the same player branch. Doncic <a href=\"https:\/\/www.cbssports.com\/nba\/news\/final-2018-19-nba-rookie-of-the-year-rankings-luka-doncic-trae-young-top-deep-talented-class\/\" target=\"_blank\" rel=\"noopener noreferrer\">posted a stunning<\/a> first pro season.<\/p>\n<p><figure id=\"attachment_29521\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-29521\" src=\"http:\/\/www.sickgaming.net\/blog\/wp-content\/uploads\/2019\/07\/from-predicting-performance-to-preventing-injuries-how-machine-learning-is-unlocking-the-secrets-of-human-movement-3.jpg\" alt=\"An athlete is shown moving sideways on an indoor track.\" width=\"650\" height=\"456\"><figcaption class=\"wp-caption-text\">Aaron Gordon training on the P3 indoor track.<\/figcaption><\/figure>\n<\/p>\n<p>The insights also help athletes avoid injuries by adopting new training techniques to change unhealthy movement patterns revealed in the data, says Elliott, who <a href=\"http:\/\/www.p3.md\/team\/marcus-elliott\/\" target=\"_blank\" rel=\"noopener noreferrer\">previously served<\/a> as the first director of sports science in MLB (for the Seattle Mariners) and as the first director of sports science in the NFL (for the New England Patriots).<\/p>\n<p>Every NBA player or draft prospect assessed by P3 receives a report that highlights their injury risks and compares them to league peers based on performance.<\/p>\n<p>\u201cAthletes come to us because they trust us to take better care of their bodies than would happen anywhere else,\u201d Elliott says. \u201cTraditionally, and still today, when these bad things happen to players, everyone says, \u2018Oh, that was a freak injury.\u2019 I\u2019m just telling you that the machine learning models predict a whole lot of these.<\/p>\n<p>\u201cI can\u2019t imagine a world where out of nowhere you suffer, say, a right tibial stress fracture \u2013 not your left one, not your femur, it\u2019s your tibia, out of nowhere,\u201d he adds. \u201cWithout a doubt, these are not random events. Sports science just has not been very good about identifying them.\u201d<\/p>\n<p>Eventually, this same information may become available to amateur athletes and everyone else, Elliott says. The same technologies could predict, for example, that a weekend warrior has too much force going through the left leg while jumping or landing plus a tiny but unhealthy rotation of the left knee and femur, causing too much friction, and, eventually, an erosion of the left knee cartilage.<\/p>\n<p>\u201cWhat if you identified that when you were 30 or 20, instead of learning when you\u2019re 50 that your cartilage is gone? That really is the future,\u201d Elliott says.<\/p>\n<p>\u201cThe power of machine learning and <a href=\"https:\/\/www.microsoft.com\/en-us\/ai?activetab=pivot1%3aprimaryr5\" target=\"_blank\" rel=\"noopener noreferrer\">(Microsoft) Artificial Intelligence<\/a> are going to help us unlock these secrets in ways that have never existed. We\u2019re already doing it but it\u2019s only in the early days of what I think is going to be a revolution in this space,\u201d he says. \u201cIt\u2019s coming. It\u2019s definitely coming.<\/p>\n<p><em>Top photo: Stanley Johnson, a forward with the NBA\u2019s New Orleans Pelicans, moves laterally inside an exercise band at the P3 lab.
