Hypetex’s carbon fiber Adidas Kromaskin stick has a micro-cell core that ensures consistent production.
A Data & Innovation brought to you by
Not until a decade ago, in 2013, was the chemical code cracked. Composite specialists with experience in Formula 1 devised a process for coloring carbon fiber while preserving its structural integrity. That work laid the foundation for Hypetex, an England-based company whose first major foray into sports is the Adidas Kromaskin field hockey stick. Other partners include New Balance, Jaguar Land Rover and, until 2021, Formula 1 itself.
That stick, adorned with Adidas’s distinctive three stripes, was a visible part of the Men’s Hockey World Cup 2023 in India, especially during the final, where Germany beat Belgium on 5-4 on penalties following 3-3 draw.
“I started using the Kromaskin stick the moment it was released,” said German national team player Christopher Rühr, an Adidas-sponsored athlete who also won an Olympic bronze in 2016. “It’s perfect for forwards like me. It has the ultimate power for goal shots but also a soft touch for when you’re receiving and dribbling.”
What Hypetex offers is more than the aesthetics benefit of infused color replacing an outer lacquer on sticks, which is prone to chipping. In combination with a micro-cell core that is inserted into the head of the stick, the Kromaskin outperformed eight premium hockey sticks, according to testing conducted by the Sports Technology Institute at Loughborough University.
The Adidas Kromaskin stick — a finalist in the Sports & Leisure category of the 2022 JEC Innovation Awards, a prestigious honor within the composite materials industry — had a 16% higher coefficient of restitution (COR), which is a measure of power transferred into the ball, and 70% less variation in COR.
Even though modern field hockey sticks are generally made of synthetic materials such as fiberglass, aramid and carbon fiber, they are prone to similar variation in performance the way wooden baseball bats are.
“What [hockey athletes] were finding previously, which was their pain point, was that there was a massive inconsistency in the performance of one stick versus the other because the production process was really dependent on the user,” said Hypetex CEO Marc Cohen. “By creating this micro-cell core, what we ended up doing was standardizing the process very much, leaving it and moving it away from the production risks that come with individuals or labor. That in itself created a much, much lower variance across sticks to the point that there was insignificant. Every stick turned out like the previous one.”
Hypetex maintains its own manufacturing facility in the southeast of England, which enables tighter quality control and longer-term competitive advantages.
“We moved production away from Pakistan, whereby a lot of probably the top 10 brands all get produced from the same factory,” Cohen said. “So any IP that gets brought out in one season for one brand, very quickly finds its way into every other brand. So when Adidas had an idea around designing a new stick and developing new solutions, they were very keen to ensure that value didn’t get diluted directly into other people’s manufacturing.”
Though the core IP around colored carbon fiber was first created 10 years ago, Cohen acknowledged that finding the best product-market fit and implementing the necessary processes for volume manufacturing took time for a pioneering process of colorizing the carbon fiber.
“So that’s where the trickiness has been, is how do you create something that is, in essence, a layer between layers, that doesn’t affect the layering system?” Cohen said. “So there’s a really interesting equilibrium that’s looked for by using fibers and using what’s called the matrix. The matrix is like a glue system that goes within the fibers and enables the structure to actually exist in the form that it’s been designed for.
“Now, by adding something, what we do — the color — to the fibers, you’re creating a layer that could be a resistance or an issue when fabricating or laminating or creating that product. So that’s where the design of the chemistry was necessary to be very tech-orientated to enable those same mechanical properties.”

Sportec Solutions’ Tom Janicot stresses the importance of communication and the advantages of the league owning its own system.
It is a question the Leaders Performance Institute poses to Tom Janicot, the Director of Video Solutions at Sportec Solutions, who has invited us to RTL Deutschland’s HQ in Cologne on a January evening to explore the German Football League’s (DFL) Video Assist hub during a round of midweek Bundesliga matches.
“The DFL decided to come here because it’s a broadcasting facility in general,” he says. “From a technical perspective, it’s a place where we’ve got maximum redundancy and maximum security for our technical installations and connections to all the stadiums in Germany.” The centre provides both the comfort – much needed for referees when making high-stakes decisions – and the technical infrastructure.
The VAR system for the Bundesliga, known locally as ‘Video Assist’, was first used across the German top tier during the 2017-18 season. It joined goal line technology, which was introduced during the 2015-16 Bundesliga season, as a staple of the match day experience in Germany. Goal line technology provides an instant, accurate judgement on whether or not a ball has crossed the goal line, resulting in a goal.

Ahead of the 2022-23 season, in March 2022, the German Football Federation (DFB) appointed the Munich-based Sportec Solutions as the Bundesliga’s officiating technology partner for the next five seasons.
It is a pioneering development, as Sportec Solutions is a joint venture between renowned sports and entertainment technology provider Deltatre and the DFL, who operate Germany’s top two divisions under the auspices of the DFB.
Keeping the Bundesliga’s Fifa-certified VAR and goal line technology in-house affords the league overall control, as Janicot explains. “When it comes to changes in setup or innovative features, there’s a huge advantage to being in control of the road maps and the directions we want to take in the future. This also reduces development and feedback cycles. It is challenging for us but also good for our product that the DFL set a very high bar in terms of standards. It is relatively achievable to get everything to work 98% of the time, but that final 2% – that’s where it costs a lot of time, a lot of effort and a lot of money sometimes to get to that stage.” Sportec Solutions achieves such accuracy using technology designed by its subsidiary, Vieww, which specialises in camera-based systems.
Earlier in the day, Janicot had taken the Leaders Performance Institute to inspect the match day setup at the BayArena ahead of Bayer Leverkusen’s meeting with VfL Bochum. In the Bundesliga, he explained, both VAR and goal line technology are set up according to two camera plans: 19 for some matches and 21 cameras for others. A prominent fixture such as Bayern Munich-Borussia Dortmund may have a camera plan of 23. Additionally, there are 14 ‘intelligent’ cameras within a stadium tracking at 200 frames per second in real-time.

Sportec Solutions will have a team onsite, both in the stadium and the TV compound outside, and will work to provide both images and audio to the VARs and operators back in Cologne. For each match, two match officials – a VAR and an assistant VAR – will work directly with two operators, who themselves are supported by an onsite backroom team.
There are eight screens at every terminal. The two largest screens relay footage from the main camera above the halfway line. The others will relay a variety of angles and enable operators to assemble a quad-split for the VAR officials to review an incident from multiple angles.
While the Bundesliga employs the full system, Vieww’s tech could theoretically be rolled out in more modest circumstances. There are already versions in the Portuguese men’s third division and the Bolivian men’s league. “The system we have built here in the Bundesliga is extremely modular,” says Janicot. “You can reduce it to a bare minimum and you can have a functional system – the processes don’t go away – you’re still going to check a red card exactly the same way. That’s something that’s very important for us, to document all of that to make sure that we have the same standards no matter the size and capability of the competition.”
The system in Germany is refined through regular VAR and operator feedback. “What we want is better decision-making and then you break it down from there. ‘OK, this is what you want to get to, how do you build every single building block to make sure that you support VARs in making the best possible decisions?’” adds Janicot, who says referees are involved in review processes.
“We had a testing phase of about one year of putting a product in front of them, getting them to give us feedback on how they liked it, how it was being used, what they didn’t like especially, and then being able to change that.
“I think it’s a luxury we’ve had in building this product from scratch over the past few years after VAR had been introduced [in German football]. We didn’t create it and then put it live and then figure out we need to change this and that. We went in with a fresh mind having had three or four years’ experience within our team and then using that to build the product as it is now.
“And now, on a weekly basis, we’re still discovering things where we get feedback from the referees or from operators and think, ‘hey, maybe we can add this or change that’. That’s a continuously evolving thing and I think that working so closely with the refereeing department – that’s really the key.”

This ongoing review process led Sportec Solutions to discard touchscreens for VARs. “If you put technology in front of someone then they’re going to feel like they need to use it,” says Janicot, who explains that VARs were initially able to zoom in on a shot for themselves without the help of an operator. “What we actually found is that it was detrimental to the operation because the operator actually had something else in mind but you had the VAR doing something else. So you had two people to control the system when actually we found it’s better to have just one person who is in charge and the VAR hands-off, simply communicating.
“That’s the thing where you can’t solve everything with technology, you need to think about what the strengths are with the different people that are at the table and what their ultimate goal is or what their role is in the operation and then make sure they have all the tools to be able to fulfil that role.”
Nevertheless, the system still looks complicated to the uninitiated and the Leaders Performance Institute was all at sea when called upon to rule on an offside decision in a trial match-based scenario. Yet any risk of information overload is offset by the VAR and operators’ training, experience and ability to communicate.
“Clear communication is the absolute key to reaching fast, precise decisions,” says Janicot. “The team needs to speak the same language, to trust each other to do their respective jobs, especially when it comes to a complex process like an offside decision.”

The DFB has brought in commercial pilots to work with referees and operators to help them to better understand how to engage in clear, direct communication techniques when issuing requests, commands and responses.
But what if the technology itself were to fail? “You need to make sure there are no single points of failure and that’s the whole way along the chain,” says Janicot. “All the way down to a single cable going to a monitor or making sure that you have a separate monitor going through a separate line, going through a separate converter etc. So making sure that you separate the work flows completely to make sure that there’s no one point where anything can fail. That applies to technology and also to people, right. What is your back-up plan if somebody gets ill the day before a match? Or if a van doesn’t make it to a venue the day before a match?
“About a year ago, we spent quite a few hours going through all the different scenarios. We called it a ‘pre-mortem’. Thinking about the absolute worst-case scenario. What happened? How can we fail? Then it’s making sure that you step back from that and going through all the different scenarios and you try as a team to cover as many as possible.”

What about imminent developments? Where does officiating technology go next? Janicot cites the potential for enhanced player tracking. “Do we at one point want to look at tracking more parts of the body than just the centre of mass?” He also refers to the use of balls containing microchips that support the use of VAR, goal line and semi-automated offside technology in Fifa competitions. “They showed it’s possible that it can be done and at Sportec Solutions we are of course having the discussion, if this is something that we need? What benefits do we get from it? And again, what benefits does it bring to the refereeing world?”
Offside decisions are another area where the DFL and Sportec Solutions are looking to further refine their process, particularly the length of time it takes to reach a verdict and the steps taken to get there. “We are looking at each segment of this decision tree and seeing ‘can we improve this? Can we improve this by work flows between the operators and the VARs or with technology?’ I think that’s something where we can make big steps forward.”
And if money were no object? “Informing the fans in the stadium, I think, is a real key part. Finding a way to do that in the best possible way. I think that’s key.”
He is optimistic for the future of officiating technology in football. “Top leagues have always had high requirements when it comes to precision and it’s also important to us because it’s an elemental part of the game. Afterall, it has influence on the decision-making process, so for us, along the whole way it was very important for us, at the end of this road, that we do get a world-class product where we have the chance to bring in our requirements in terms of quality and reliability but also our wishes and ideas for our future.
“We absolutely feel confident that we are in a very good position right now and in a very good position to develop whatever direction we might want to go in terms of the next years for refereeing technologies.”
The United States Tennis Association is using data to educate and inform players and coaches alike.
A Data & Innovation brought to you by
This particular maxim may indeed be true more often than not, but two of the world’s top players — reigning US Open champ Carlos Alcaraz and his finals opponent, Casper Ruud — are actually covering a lot more distance, according to data analysis from USTA’s player development team.
“They’re running significantly more because they’re covering more ground to hit the forehand and be more aggressive,” said Geoff Russell, USTA’s Senior Manager for Professional Players. “So maybe, them covering more distance is, relative to the tactical game style that they’re trying to play, that might not be a bad thing. That might be an efficient thing.”
The running habits of the Nos. 1 and 3 ranked players are but one insight gleaned from the Hawk-Eye player and shot tracking data available at every Grand Slam event, including the Australian Open, which took place in January. What the USTA has prioritized in recent years is in-depth assessment of match data in order to inform training. Practice sessions and workouts are tracked by wearable technologies to ensure that players are preparing appropriately to compete and contend at major tournaments.
A key figure in this initiative is Paul Robbins, Kinexon’s EVP of Sports Performance and a member of the USTA Sport Science Committee. Robbins pioneered this type of physical performance monitoring for NBA players as the Director of Elite Performance at STATS, which owned the first tracking system implemented in basketball, SportVU. He continues to consult extensively within the NBA.
Robbins jokes about how impressive the USTA Sports Science Committee is, noting that he’s just about the only one without an MD or PhD. (“I always say I’m the dumbest guy in the room,” he quipped with a laugh.) Now, in conjunction with Russell, Performance Manager David Ramos, medical advisory group member Mark Kovacs and others, Robbins is helping spearhead innovative analysis and training programs in tennis.
“How do these guys actually play? How do we actually then train somebody to play at this level? Their accelerations or decelerations, the loads, the work capacity you need over a two-week period of time in the tournament — things like that,” Robbins said. “It’s basically bringing everything I’ve done for the NBA for 12 years, now, we’re actually at that level for the USTA to be able to do that in our development of our US players.”
During the US Open, the USTA player and coach development staffs introduced the Physicality Index and published a series of web stories using this new metric to describe the intensity and toll of matches. One such piece, discussing the play of the men’s semifinalists, shared the aforementioned insight about Alcarez and Ruud, whose respective 6.9 and 6.6 Physicality Index scores dwarfed Karen Khachanov (5.2) and American Frances Tiafoe (4.8), as did their high-speed distance covered and number of explosive movements.
That public-facing metric was designed to engage and interest fans and, at times, included some sample workouts that competitive players could undertake to prepare for such demands. But the player development work runs much deeper.
Russell and Robbins drove from the greater Phoenix area out to Indian Wells for the BNP Paribas Open in October 2021, and over the course of the roughly eight-hour roundtrip drive, they designed most of the new tech-infused, player development program.
The first order of business was to assess the current practice routines among highly rated junior players at the USTA campus in Lake Nona. Performance Analytics Coordinator Katherine Gonzalez tagged every drill in the data management platform to help develop these baselines.
Early questions raised by Robbins, whose specialty is in metabolics, were about training the necessary energy systems: “Do we need a 15-minute drill? if you’re trying to mimic what’s happening in a match, that’s two minutes. You want to go at a much higher intensity to do that.”
One revelation of this work: several coaches were using mini-tennis — a rally-driven exercise using only the service boxes — early in training session to get their players loose.
“They were calling it their warmup,” Robbins said, “and that turned out to be the highest intensity drill. It’s like, ‘I don’t know if we want to start with the highest-intensity drill.’”
Providing education to the coaches is the important first step, and they’ve been largely receptive to the explanations they’re hearing.
“Coaches have the right intention,” Russell said. “They’re trying to do the right things, but they just need to understand the why — the effects of what they’re doing.”
USTA leadership has been supportive, he added, because every stakeholder in development stands to gain from the infusion of data and video to track not only physical load but stroke volume and heart rate, too. RPEs, the common shorthand for rate of perceived exertion scores, are also valuable data points from the athletes themselves even if they are inherently more subjective.
These sources appeal to tennis coaches, strength coaches, athletes, the medical team and also the mental skills coaches, with Russell noting the applicability of heart rate data as a proxy for pressure management. After all, physical, technical and tactical performance are inherently intertwined. The USTA performance team’s preview of the women’s semifinal, for example, used the data to show how Ons Jabeur and Caroline Garcia minimized their exertion by controlling court position, rarely standing far behind the baseline, by using their strength to return shots from closer in and rallying with powerful forehands.
Every player has his or her own style of play and requisite physical thresholds, but as the data gets collected and analyzed, the USTA can create clusters, or buckets, of player profiles who would all benefit from similar training. That serves as a base for further personalization.
“Going back to Alcaraz, I mean, those accelerations and decelerations that he had — and not only just one or two, he just kept doing it — you’ve got to train for that,” Robbins said. “And that’s what we’re trying to do is understand what the matches are. And then how do we how do we adjust our drills to do that?”

Ludimos’ solution is used by more than 19,000 players in 15 countries, including the IPL’s Royal Challengers Bangalore.

“I lost all my fundamental flow and feel for the bat,” Rajagopal recalls. He adds, “Coming from India, cricket is kind of in our blood, in my blood, and I could live without anything but not without cricket. But in 2018, there was a point where I literally thought about stopping cricket because I wasn’t enjoying the game anymore. I wasn’t scoring. I wasn’t playing well. My performance was very bad.”
Around the same time, Rajagopal was helping coach the club’s junior players and was surprised not to find any apps to help track their progress. In his professional life, he is a data scientist and AI engineer, so he set out to build his own solution.
That product is now Ludimos, a smartphone-based cricket tracking and training app that has been used by more than 19,000 players across 15 countries. Among the team clients are nine national cricket associations, including those in Scotland and the Netherlands, as well as Royal Challengers Bangalore of the Indian Premier League (IPL).
Ludimos can analyze video from multiple viewpoints and provide tracking data on ball and bat. An assessment of player biomechanics is in development. And the platform is also a communication tool that enables coaches to assign drills, evaluate them upon completion and return annotated videos with tips.

“Our current core value prop is the ball tracking,” Rajagopal says. “So our ball tracking technology is good enough that it is already adding value to both batters and ballers, and in our roadmap, the next thing we have is to unlock the bat tracking and then the biomechanics. Then at that point, then we can merge everything together and have contextual analysis of the player in full.”
RCB, in fact, revealed this week that one of their newest additions — bowler Avinash Singh — was the direct result of its Hinterland Scouting program, a data-driven talent identification tool powered by Ludimos. Singh has never played professionally and mostly played tennis ball cricket until less than a year ago, yet now he is the first of more than 10,000 registrations to make the RCB roster through this program and has bowled 145 kilometers per hour (90 mph), an elite pace.
In a video interview, RCB head of scouting Malolan Rangarajan described Hinterland Scouting as a “very, very objective way of identifying talent where we don’t use human eyes” while likening the bowling action of Singh to Umran Malik, the IPL’s fastest bowler.
As part of an innovation contest in 2021, Ludimos earned second place in the competition hosted by Cricket Australia and HCL, with distinction for its player development tools. Ludimos is also a graduate of the Stadia Ventures accelerator program and is now raising a €1.5 million seed round, of which €300,000 was slated to come from a crowdfunding campaign on Seedrs. (By mid-January, Ludimos had exceeded that goal and raised €314,511.)

While other sports — most notably baseball — have seen great advances in the understanding of the sport via publicly accessible databases and research, cricket’s advanced data has been more closely held.
“We don’t have any open data set about what’s been collected and how it’s been used, which means that there are only a handful of companies in the world that actually do this,” Rajagopal says. “And we are the only one of them, which does all three, which is bat tracking, ball tracking and biomechanics.”
Video review helped remedy Rajagopal’s own swing woes. He asked friends on the team to record him for three weeks straight and reviewed the clips with a coach.
“Even though the exact same sentence was said to me by several coaches — ‘that your head is moving away, that your weight is actually falling off and not coming towards the ball’ — I could never visualize what that actually meant, how that would look like, until I saw him pointing on the screen where he said, ‘Your head should be here, but it’s few pixels to the right or to the left,’” he says, describing the experience as empowering.
With small changes, Rajagopal dramatically improved his batting results, regaining his confidence and triggering his pursuit of Ludimos to create similar opportunities — with greater tech-driven features — to everyone. (Ludimos is an amalgamation of Latin words that try to capture the process of improvement: self-reflection, practice, habit formation.)
Rajagopal says Ludimos was designed for all age groups of cricket, recognizing that most club coaches might work with 11 year olds on up to 40-somethings. The older bracket will seek more detailed analysis; youth players will seek a different experience. “For 11- to 15-year-olds, it’s more about having fun and feeling for the game,” he says. “It’s more about gamification, so we turn our data and AI into a way that they can use as challenges and leaderboards.”
Ben Ferbrache, the cricket development manager for Guernsey, manages and coaches the junior programs for the small island state situated in the English Channel.
“It’s a really good way of tracking a player’s progress, especially with a lot of our guys that are going from one age group to the next,” he says. Ferbrache notes the ease of use, both for the players and for the coaches to record and assign their own practice drills. “What we find is kids love technology,” he adds. “Everything is on a phone or an iPad these days. So that’s where we were like, ‘Why don’t we just embrace the technology, and the kids will actually start using it?’”

‘Everything in athletics is determined by ground forces. If you want to jump higher, you have to convert horizontal forces to vertical forces as efficiently as possible. We increase ground force,’ says Founder Stuart Jenkins.
A Data & Innovation article brought to you by
The study was conducted by a professional baseball organization — Blumaka is not publicizing which one–with movement tests performed on 190 athletes. Data from the biomechanics lab was collected through KinaTrax’s 3D marker-based motion capture system with integrated force plates. Among the findings from the study were 90% of athletes saw an increase in linear body velocity while wearing the insoles compared to not wearing them, 80% increased their lead leg ground-force production, 70% increased their back leg g-force production, and 80% had an increase in front knee stability.
“I can’t think of any sport where slipping helps other than curling,” says Blumaka founder Stuart Jenkins. “Everything in athletics is determined by ground forces. If you want to jump higher, you have to convert horizontal forces to vertical forces as efficiently as possible. We increase ground force.” On the lab testing, Jenkins adds: “They were running and then coming to a complete stop, looking at how fast do you start and how fast do you stop? They were also doing baseball things like a pitcher coming off a mound, what happens to that front leg when it hits the ground? Is that foot sliding down the mound or is it stopping so that you can get velocity on the ball?”
Konnect insoles are made from 85% of recycled foam materials, including a thermoplastic polyurethane (TPU) surface. Jenkins, 63, has spent over 40 years in the footwear industry including his previous role as VP of Innovation and Product Development at Deckers Outdoor Corporation, which owns brands such as UGG and HOKA. Investors in Blumaka include Donnie Ecker, the current bench coach and offensive coordinator for the Texas Rangers and former hitting coach for the Giants.
“Most insoles have cloth on the top and most socks are made out of fabric. You put two things together, a sock and a fabric that have the same coefficient of friction, they slide,” Jenkins says. “What we did is we picked a material that had a tackiness to it. If you put [Konnect] under a microscope, you would see these micro-grip patterns that we’ve built into the mold so that it would grab this sock more effectively.”
Giants outfielder Mike Yastrzemski has been among the staunchest advocators for Blumaka, wearing the insoles during games over the past two seasons after being connected to Jenkins though a friend of a friend. Several teammates, including Tommy La Stella and Evan Longoria followed Yastrzemski’s lead in purchasing the insoles. Testing on Yastrzemski’s swing showed his rotational acceleration increased by 5-7gs [g-force] wearing the insoles versus without, according to The Athletic.
“[Konnect] lasts something in the neighborhood of 10 to 20 times longer than the insoles they’re putting in these athletic shoes from a cushioning and durability standpoint,” Jenkins says. “Mike Yastrzemski told me he normally goes through three insoles a year in his baseball cleats. He has now played two consecutive seasons in one insole, our insole. Think about that from an environmental standpoint.”
“I’ve tried every kind of insole there is on the market,” Longoria, now a free agent, told The Athletic last summer. “I’ve had custom orthotics made, I’ve tried all the over-the-counter stuff you can buy. This [Blumaka] has by far been the best result that I’ve gotten from an insole.”
Jenkins says that 10-15 PGA Tour golfers wear Blumaka during tournaments. California-based athletic sock company Drymax has a distribution agreement with Blumaka, which has sold its Konnect insole at full price ($59) on its website to all professional athletes wearing the product and does not yet have any paid endorsers. A report from Fox Sports found that just 11 of 695 MLB hitters did not wear batting gloves in plate appearances during the 2021 season, and Jenkins thinks his insoles could become a just as common piece of equipment.
“The reason everyone wears batting gloves is because it makes you a little bit better, because slipping is not a good thing,” Jenkins says. “It’s gonna be the same way with insoles. Why would you want to slip? We’re not going to make people go from the sandlot to Yankee Stadium and be a star, but we’re gonna make the stars at Yankee Stadium a little bit better.”
