Tennis fans, especially those hooked on the Open tournaments, are able to enjoy a season of top-flight games almost a year-long, beginning with the Australian Open in January and ending with the US Open in September. Many more events – whether individual tournaments or internationals – are sandwiched in between.
Whether it’s Carlos Alcaraz, Jannik Sinner or the legendary Novak Djokovic in the men’s tournaments, Aryna Sabalenka, Iga Swiatek or Coco Gauff in the women’s, the level of individual talent rises constantly. These improvements are attributable to the amazing natural talents of the athletes, combined with the best coaching the sport can offer. The right coach can make all the difference between being a player and being a champion.
While elite-level coaches are still very much the preserve of elite-level players, the ability to improve natural talent through tennis coaching is open to players at all levels. Looking to level this playing field further is Norwegian B2B sports technology company SportAI.
Founded in late 2023 by tech and software industry experts Lauren Pedersen (CEO), Felipe Longé (chief technology officer) and Trond Kittelsen (head of commercial), the company’s basic mission is to enhance tennis technique through tactical analysis, coaching and commentary. With expertise in computer vision and machine learning, SportAI looks to use artificial intelligence (AI) to offer instant data-driven insights to training facilities, teams, broadcasters, retailers and equipment brands. Still in its early days, the company has raised $3.6m in funding to date.
For the love of tennis
The company’s management combines technology expertise and a passion for tennis. In addition to extensive experience growing global tech firms, Pederson competed in NCAA Division 1 college tennis and represented Norway at the 2023 ITF Tennis Masters World Championships. As well as being an entrepreneur and sports technology product expert, Kittelsen was CEO of Sevensix Tennis, the provider of an app designed to analyse tennis technique to help players upgrade their game by comparing their technique to that of a professional player.
Kittelsen describes the team as tennis “nerds”, watching all the games and following all the stats. But on a serious note, he insists the company is on a mission to democratise all the insight for everyone, and to do that, it needed a great tech team comprising machine learning engineers, AI experts, mathematicians, and experts in physics and physiology. Added to these are people with a proven track record in commerce.
Pedersen is adamant that with her company’s solution, insight into how to play tennis effectively can now be delivered cost-effectively and in a way that is comparable to the likes of Strava and Fitbit for runners. She notes that until now, a vast number of participants, without access to complicated technology, could play many games of tennis, yet not have any idea about how they had hit shots or how to improve.
The basic principle of the SportAI platform is that every movement a tennis player makes matters. After taking in video of tennis action – by using a standard mobile device such as an iPhone, sophisticated TV setups, or court-mounted cameras – the software uses machine learning and biomechanical analysis to build detailed 3D visuals of playing style. Once ingested into the SportAI system, data is uploaded to the Amazon Web Services (AWS) cloud, analysed and made available in seconds.
The SportAI app uses computer vision to check a player’s limbs and joints, tracking movement and the load on the racquet during shots and the follow-through of the racket after the ball impact
The app uses computer vision to check a player’s limbs and joints, tracking movement and the load on the racket during shots and the follow-through of the racket after the ball impact. It can measure biomechanics, swing curve, power generation and where the players hit the ball. It shows clearly the kinetic chain in making a shot – that is the sequence of shot creation from hip, shoulder and wrist position – generating an analysis from which it’s possible to see what needs to be improved.
For example, ball speed is a function of wrist speed, and the SportAI app can generate a swing curve, comparing it to that of a professional player. The AI within the app can display the velocity and rotation of hips and shoulders. All of this can be used by coaches to improve performance.

The subsequent data generated can be provided to individuals or to sports federations, academies, or equipment providers and manufacturers to see how people play and what can be done to improve technique. The data can also be compared with that of elite players to receive personalised improvement recommendations.
The analysis can also automatically jump to key points if there is something specific to focus on. Stats could include how many forehand shots a player hits in a given time, or they can generate highlights such as the longest rally in a game or action with the highest intensity.

“If you take a tennis lesson today, it might cost $100 an hour anywhere in the world. And you might have a good coach, [but even if] you had three or four good coaches looking at your serve feedback, there would be no data to back it up. Now, with advances in computer vision and machine learning, you could change that,” says Pedersen.
“So instead of having to have sensors on your body to track movement and biomechanical analysis, now almost every pixel on the video starts to become something you can use to track and gather data from, and then use that [data] to power different experiences and feedback,” she adds.

“[Manufacturers] are potential customers for us to take on this type of technology. Sensors themselves are just not scalable – you would either have to put them on a body or on a racket. It is not as scalable as being able to have a video that can come from a mobile phone or from court-mounted cameras, [which] are becoming more common around the world.”
The SportAI business model is mass market and relies on subscription, available to individuals, federations or equipment manufacturers. Kittelsen adds that manufacturers are particularly interested in the biomechanics information that the video can generate.
“[The video can] track the rotations, the speed and the height of the ball, the precision of the ball. [Manufacturers] do not have a lot of data on biomechanics, and so now we can help them with that. It’s not just looking at the result of hitting the ball; it’s looking at how you get that result, and how you improve the swing. And instead of then [just asking] players how the racket felt, we can understand [how they perform] with data,” says Pedersen.
From Hawk-Eye to AI
In an expression of the confidence it has in the system, SportAI says in testing, it had a player serving a ball and captured data using a standard phone with a standard camera at 30 frames a second at 1080px resolution. This had 98% precision compared with data generated using Hawk-Eye, the ball-tracking technology that is currently used at all the major tennis tournaments.
Yet despite the high-tech involved, Pedersen also emphasises clearly that the solution is for everybody. “This is not just about supporting the top, elite players, because the elite players will often have a performance analyst coach on their team who’s manually doing this on video and can deliver it. But the other 90-something million tennis players typically have no access to this data, so we want coaches and players around the world to get it,” she says.
“It’s sort of universal how you create power around [shots], and [knowledge of that] is something we see that recreation players and beginner players [would want]. It’s super motivating to want to get better. And when you have some ground data, you can go out and improve. People then want to go back on court because they want to get better,” adds Pedersen.
In terms of development challenges, the company says a number of business and technical issues have had to come together to get the company to where it is. In addition to gaining investment, the company has had to educate its market by showing coaches and players how they can use the technology and how it can be simultaneously better for both of them.
AI is becoming a commodity – everyone is using AI in some form. Yes, it can make mistakes, but you can still train it to be smarter and better. We see it as a tool to help and assist tennis coaches Lauren Pedersen, SportAI
“In all businesses, in all verticals, there’s scepticism. It was the same with Hawk-Eye. Ten years ago, nobody believed Hawk-Eye to be accurate enough. Now they’re accepting it. That’s going to happen with AI. AI is becoming a commodity – everyone is using AI in some form. Yes, it can make mistakes, but you can still train it to be smarter and better. We see it as a tool to help and assist coaches. It’s not taking their place, because, like you see in other industries, it becomes much more effective and efficient, and makes better decisions.”
According to Kittelsen, one surprise the company found using AI in its system was discovering its basic power, how just a single camera with coded AI algorithms can detect and display complex rotations and velocities. “But also, I want to add that the AI is still doing [some things] wrong, so we have to teach it. We have to teach the machine to take away the error percentages. And with the new cameras [on new phones], the quality of video goes up. The processors are faster.”
Acing video capture
The rest of 2025 will see SportAI rolling out the system for its first customers. The company believes it is being helped by tennis clubs increasingly mounting cameras around their courts, aided by the more powerful and cheaper cameras on phones, resulting in better quality video being more accessible for clubs and federations.
The company has also forged a partnership with the Matchi booking system for racket sports venues worldwide. Matchi currently manages about 15,000 tennis courts, 2,000 of them camera-enabled. SportAI will be taking in video streams from these courts to analyse action. It is also working with some equipment brands to generate technique analysis and offer equipment recommendations.
A key technical development for the company will be moving from cloud processing of data to performing data processing at the network edge. In addition to cost savings, this is intended to make it even faster to analyse data and add the capability to perform 3D video analysis. There will also be work on creating AI agents that can be attached to the app, which could be aligned to a federation or an individual player.
Pederson is adamant that SportAI is in business for the long run, and that the data the app picks up could also be useful for injury prevention and healthcare in general. For example, it could show how players’ joints bend and flag any extreme styles that could lead to injury. “Our vision is to democratise access to this type of data. It’s about seeing that value happen worldwide. We’re passionate about sports and technology. We want to see the most kind of progressive coaches, academies and brands taking it on board and really changing the game.”
Researchers Leon Y. Xiao (City University of Hong Kong & beClaws.org) and Solip Park (Aalto University) analyzed the 100 top-grossing iPhone games in South Korea.
84% of games with loot boxes disclosed probabilities—compared to just 35% in the Netherlands and 64% in the UK.
Only 41% of disclosures were easy to find, meaning many players may fail to access the information and remain confused or uninformed.
South Korean regulators have backed the law with active enforcement, identifying noncompliance and forcing companies to fix mistakes. Separately, fines were levied against major South Korean publishers like Nexon for misleading disclosures.
“South Korea is showing the world that loot box regulation can work—but only when actively enforced,” said Xiao. “Industry self-regulation has failed globally. If governments really want to protect players, we need enforceable laws with real penalties.”
The authors call on other countries to follow South Korea’s lead in actively enforcing video game regulations, but also to strengthen standards so that disclosures are clear, accessible, and independently evaluated for accuracy.

Once you’ve decided on a size, there are a number of other important aspects of your next monitor to consider. Some of these factors may matter more for certain uses—for example, gamers generally care more about higher frame rates than office workers do—but they’re all handy to know going in.
Resolution: The bigger the monitor, the more it will benefit from higher resolutions. That will allow you to have app windows that take up less space but are still legible. Most monitors today are typically 1080p (1920 x 1080), 1440p (2560 x 1440), 4K (3840 x 2160), or even 5K (5120 x 2160).
Refresh rate: This refers to how many times the display can refresh the picture per second, measured in hertz (or Hz). A higher refresh rate makes all movement and animation look smoother because you’re seeing more information. For productivity, 60 Hz is probably enough, but gamers will generally want a panel that can at least hit 120 or 144 Hz. 240 Hz has become the new standard for high-end gaming monitors, but there are now extreme models that go up to 500 Hz and beyond. You’ll need a powerful enough computer that can maintain a high frame rate to take advantage of these high refresh rates, and you usually have to enable this feature in your operating system’s display settings.
Panel type: Monitors usually have a type of LCD (liquid-crystal display) panel. Three of the most popular options—twisted nematic (TN), vertical alignment (VA), and in-plane switching (IPS)—are all different types of LCD panels, and all use TFT (thin-film-transistor) technology too. Each is popular for different reasons: IPS for color, VA for contrast, and TN for speed with higher refresh rates and response times. IPS has become especially popular thanks to its growing refresh rate speeds. Mini-LED uses a more advanced backlighting solution that uses a number of lighting zones to more accurately and efficiently control pixels. These tend to be the brightest monitors you can buy. OLED (organic light-emitting diodes) panels take that even further, allowing the monitor to control individual pixels, including turning them off entirely to create extreme contrast. These are becoming highly popular in gaming monitors, in particular. You should think about what’s most important to you (great color? thin form factor? max brightness?) to choose the best panel type for your needs.
Nvidia G-Sync/AMD FreeSync support: A gamer-specific criteria, these two features let monitors adjust their frame rates based on the games they’re playing. This reduces screen tearing without affecting performance. G-Sync is made by Nvidia and FreeSync comes from AMD, and while FreeSync monitors can usually work with most modern Nvidia graphics cards, G-Sync doesn’t work with AMD cards, so make sure everything you have is compatible when buying.
HDR support: This isn’t crucial for productivity, but if you watch a lot of media or play games, it’s nice to have. Just like on TVs, HDR dramatically expands the range of colors a screen can reproduce, leading to more vivid pictures. Content still has to support HDR, but many sources do these days, so it’s often worth springing for. You’ll find lots of monitors that say they support HDR (such as DisplayHDR 400 certification), but in almost all cases, you’ll need a Mini-LED or OLED screen to really get proper HDR.
Port availability: A crucial but easy-to-overlook factor is what kind of ports the monitor has for connecting your devices. Most typically come with one or two HDMI inputs, and a DisplayPort input, which will cover most needs, but it’s always a good idea to check what your setup needs. More expensive monitors can function as USB hubs, letting you connect all your peripherals and accessories directly to your monitor. Conversely, check out our Best USB Hubs guide if you need to expand your computer’s port options without paying for a more expensive monitor.
Built-in KVM switch: A KVM (Keyboard, Video, Mouse) switch is a device that helps you easily switch your monitor, keyboard, and mouse between two different computers or source inputs (like a gaming console). If you have one setup for both a work and personal computer, or a computer and gaming console, having a KVM switch built into the monitor means you can easily switch everything between your two devices without needing an external KVM switch.
For most people, though, “if results are strong, maybe you don’t need another scan for five years,” says Wagner. “If they’re lower, lifestyle interventions can help, and you may want to recheck in a year.”
Radiation exposure is negligible, less than a chest x-ray. But the psychological impact can be more complicated. For some, the numbers motivate: “When I did a body composition test at 36, I had way more body fat than I expected,” Cheema says. “That pushed me to change my workouts and eating patterns in ways that improved my health—something BMI alone wouldn’t have prompted.”
For others, especially those with histories of disordered eating or body image issues, it can be destabilizing and overwhelming. Numbers can become another metric to obsess over rather than a tool for health. “It can be overwhelming if you don’t have a clinician to interpret the results,” Gidwani says. “That’s why I review all of my patients’ scans with them.”
Cheema agrees: “Too much detail without guidance risks overwhelming people with information that isn’t clinically actionable.”
“I don’t think DEXA gives too much information compared to, say, a whole-body MRI, which can reveal incidental findings that can cause anxiety and lead to unnecessary interventions,” says Gidwani. “Its data points are actionable: decrease body fat, reduce visceral fat, increase muscle.”
Experts emphasize that actionability is key. “The most important metrics are visceral adipose tissue and total body fat percentage, especially when tracked over time,” Cheema says. “But DEXA also breaks things down by arms, legs, trunk, etc. That can veer into aesthetics rather than health.
Should You Get One?
If you’re 65 or older, or at risk for osteoporosis, your doctor may already recommend a DEXA scan for bone health. For women in perimenopause, when bone density can drop by as much as 20 percent, an early baseline scan could flag risks years before they become urgent.
DEXA also detects sarcopenic obesity, where muscle loss occurs alongside high body fat. “Someone may look normal weight on a scale, but a DEXA can reveal poor muscle-to-fat balance,” Gidwani says.
Beyond those groups, the use case narrows. Athletes, bodybuilders, and people on GLP-1 medications may find the data genuinely useful. For generally healthy adults who exercise, eat decently, and check in with a doctor, many clinicians are indifferent.
“For a healthy individual, I wouldn’t universally recommend it,” Cheema says. “Lifestyle changes and basic care may matter more than getting a DEXA.” There are alternatives—bioimpedance scales, Bod Pods, and AI-enabled wearables—but none are as accurate as DEXA. For now, it remains the most precise, if expensive, tool available.
Final Takeaways
My DEXA results were somewhat humbling. Despite near-daily workouts and a decent diet, the scan flagged more body fat than I expected and the beginnings of osteopenia in my spine. The bright side was an “excellent” visceral fat score, something I’ll be bragging about indefinitely.
Catching early bone loss feels actionable; I can tweak my workouts to prioritize strength and mobility. But the body fat percentages have lived in my brain rent-free ever since, without offering much in return. I don’t plan to shell out a few hundred dollars for another scan anytime soon, so I may never know if my adjustments are actually working.
That’s the paradox of DEXA. For those with medical risks, it can be invaluable. For athletes chasing marginal gains, it’s another knob to turn. But for the rest of us, it’s a reminder that data is only as useful as what you’re willing or able to do with it. In the end, DEXA doesn’t promise longevity so much as it promises numbers, and numbers alone don’t add years to your life.
