Health and Fitness Tracking Goes Mainstream

Since September, Jeanette Cajide has armed herself with an Elite heart-rate variability monitor. And a temperature-controlled mattress pad. And a Levels continuous glucose monitor. And an Oura Ring that also measures heart-rate variability along with resting heart rate, respiratory rate and temperature. “Yeah, I’m a little crazy on the devices,” says Ms. Cajide, director of strategy and operations at consulting firm Clareo.

She’s got good reason. After returning to competitive figure skating four years ago, she won a national championship. Then last September, she broke her leg while landing an Axel jump. Ms. Cajide, who is 44 years old, competes again in eight weeks—against many skaters half her age.

She is trying to override nearly two decades as a “sedentary adult,” working in tech and investment banking. “I’m trying to make up for lost time. It’s me against time,” she says. “The sensors and data allow me to optimize for getting the most mileage out of my body.”

There is no escaping the Quantified Self movement. Measuring biomarkers used to be the preoccupation of extreme athletes and extreme geeks. No more.

“I think the attitude is shifting. The seriousness of the pandemic has made people realize that gosh, isn’t it a good idea to have a sensor,” says Michael Snyder, chairman of the department of genetics at Stanford University’s School of Medicine, whose research, among other studies, indicates data from smart watches—alterations in heart rate, steps and sleep—can be used to detect Covid-19 as early as nine days before symptoms.

Until relatively recently, health-minded people were excited to track their steps and heart rate. Now they can perform their own urine and blood tests, conduct body-fat scans and monitor their emotions. Soon they may be able to monitor their rate of aging to take steps to slow it down. Rings, watches, patches and apps that monitor biomarkers have taken off, buoyed by a pandemic that alerted everyone to “underlying conditions” they might not be aware of.

Fitness and tech companies, already adroit marketers, jumped on the opportunity, intriguing people like Ms. Cajide. They “have created this persona of somebody who’s striving and they’ve done a really good job of it,” says Joe Vennare, co-founder of Fitt Insider, which produces a newsletter and podcast and invests in health, wellness and fitness. Fitness-tech startups raised $2.3 billion in 2020, 30% more than the year before, according to market-intelligence firm CB Insights.

People who track their data are constantly sharing online. One recently tweeted a graph comparing her heart rate: “me walking alone, hauling it: 140 bpm vs. me walking normal with my friend: <110 bpm.” Another boasted that since he began wearing a sleep-tracking device, he has averaged 8.25 hours of uninterrupted sleep a night. Another tweeted eight separate graphs of jagged green and blue lines with an ominous question: “Anyone have heart rate or respiratory rate peaks in the night that is DOUBLE their normal value? I don’t know if this is a medical problem or just the measuring device.”

Self-trackers often fixate on factors that might influence their performance. “It’s interesting to look at these things and learn about yourself. They can help you understand things you couldn’t unearth on your own,” says Chris Bailey, co-founder and chief technology officer of startup NatureQuant and an endurance mountain biker. He’s currently testing the Apollo Neuro, which isn’t a tracker, but is considered another bio-hacking device designed to increase heart-rate variability and optimize performance. Worn on the wrist or ankle, it is designed to reduce stress and recalibrate the nervous system using varying-frequency vibrations that can be programmed to make you more alert in boring meetings, focus better during cognitive or athletic activities and recover more quickly after physical exertion. Mr. Bailey’s early verdict: “It’s a little hard to tell. It helps with focus a little bit, maybe, but it’s certainly not something that 2Xes your performance.”

Individuals react differently to caffeine, pasta, late nights—almost everything. Last year, Whoop added a journal to its sleep-tracking app. In the journal, users can log more than 70 behaviors to see how, over time, they might affect sleep and performance. Activities include taking medication like Advil, drinking wine, reading before bed and having sex. In a podcast introducing the change, Whoop executives said users had frequently requested the sex-tracking feature. For some, sex can raise core body temperature which is counterproductive to sleep, the company explained, so you might want to take that into account the night before a big event.

As for alcohol: Not a good idea, according to Whoop. While many people think alcohol helps them sleep better, it disrupts the repair and recovery that is supposed to happen during slumber. It interferes with physically restorative slow-wave sleep and it “crushes” your mentally restorative REM sleep, Emily Capodilupo, now Whoop’s vice president data science and research, explained in a company podcast. It messes with your heart rate, suppresses recovery and increases the chance of injury.

When Ms. Cajide, the figure skater, heard about sleep tracking, she thought it was silly. “I don’t care what happens at night,’” she recalls thinking. Then she learned the significance of heart-rate variability—not heart rate, which is beats per minute—but the variance in the length of time between heart beats. HRV is a key indicator of how fit, recovered and ready you are to perform, and can be greatly affected by the quality of your sleep. “I went down the rabbit hole,” she says.

Now she wears a continuous glucose monitor—a patch attached to the underside of her arm. Its data displays on her phone, telling her what foods are spiking her glucose and how efficiently she is managing her energy. She programs the temperature of her mattress pad to gradually fall to 62 degrees in the middle of the night, to bring down core body temperature and thus positively influence her heart rate and HRV. So far it has gotten those metrics to their “best points mid-sleep ever,” she says.

She uses her Fitbit as an alarm clock because its vibration doesn’t spike her heart rate and scramble her metrics. Then she checks the data from her Oura Ring and compares it to that of her Elite HRV, “to make sure they’re giving me the same information.”

The information tells her how hard to train—whether she will attempt an Axel, the jump that resulted in her broken leg last fall. Her current program includes two. “On a good recovery day, I’m more comfortable taking risks,” she says. That is crucial because she has only recently recovered but competes again in just eight weeks.

Dr. Snyder at Stanford understands the obsessiveness. He wears four smart watches, two on each wrist, to figure out what variables are the best to measure and “also sometimes one will run out of batteries.” He believes Ms. Cajide’s kind of self-tracking is critical to the future of healthcare, saying, “If people really care about their own health, they are going to have to take charge.”

The marketplace has spoken and, at least for now, it’s showing preference for hybrids and plug-in hybrids (PHEVs) over battery electrics. That makes Toyota’s foot dragging on EVs (and full speed ahead on hybrids) look fairly wise, though the timeline along a bumpy road still gets us to full electrification by 2035.

Italian supercar producer Lamborghini, in business since 1963, is also proceeding, incrementally, toward battery power. In an interview, Federico Foschini , Lamborghini’s chief global marketing and sales officer, talked about the new Urus SE plug-in hybrid the company showed at its lounge in New York on Monday.

The Urus SE SUV will sell for US$258,000 in the U.S. (the company’s biggest market) when it goes on sale internationally in the first quarter of 2025, Foschini says.

“We’re using the contribution from the electric motor and battery to not only lower emissions but also to boost performance,” he says. “Next year, all three of our models [the others are the Revuelto, a PHEV from launch, and the continuation of the Huracán] will be available as PHEVs.”

The Euro-spec Urus SE will have a stated 37 miles of electric-only range, thanks to a 192-horsepower electric motor and a 25.9-kilowatt-hour battery, but that distance will probably be less in stricter U.S. federal testing. In electric mode, the SE can reach 81 miles per hour. With the 4-litre 620-horsepower twin-turbo V8 engine engaged, the picture is quite different. With 789 horsepower and 701 pound-feet of torque on tap, the SE—as big as it is—can reach 62 mph in 3.4 seconds and attain 193 mph. It’s marginally faster than the Urus S, but also slightly under the cutting-edge Urus Performante model. Lamborghini says the SE reduces emissions by 80% compared to a standard Urus.

Lamborghini’s Urus plans are a little complicated. The company’s order books are full through 2025, but after that it plans to ditch the S and Performante models and produce only the SE. That’s only for a year, however, because the all-electric Urus should arrive by 2029.

Thanks to the electric motor, the Urus SE offers all-wheel drive. The motor is situated inside the eight-speed automatic transmission, and it acts as a booster for the V8 but it can also drive the wheels on its own. The electric torque-vectoring system distributes power to the wheels that need it for improved cornering. The Urus SE has six driving modes, with variations that give a total of 11 performance options. There are carbon ceramic brakes front and rear.

To distinguish it, the Urus SE gets a new “floating” hood design and a new grille, headlights with matrix LED technology and a new lighting signature, and a redesigned bumper. There are more than 100 bodywork styling options, and 47 interior color combinations, with four embroidery types. The rear liftgate has also been restyled, with lights that connect the tail light clusters. The rear diffuser was redesigned to give 35% more downforce (compared to the Urus S) and keep the car on the road.

The Urus represents about 60% of U.S. Lamborghini sales, Foschini says, and in the early years 80% of buyers were new to the brand. Now it’s down to 70%because, as Foschini says, some happy Urus owners have upgraded to the Performante model. Lamborghini sold 3,000 cars last year in the U.S., where it has 44 dealers. Global sales were 10,112, the first time the marque went into five figures.

The average Urus buyer is 45 years old, though it’s 10 years younger in China and 10 years older in Japan. Only 10% are women, though that percentage is increasing.

“The customer base is widening, thanks to the broad appeal of the Urus—it’s a very usable car,” Foschini says. “The new buyers are successful in business, appreciate the technology, the performance, the unconventional design, and the fun-to-drive nature of the Urus.”

Maserati has two SUVs in its lineup, the Levante and the smaller Grecale. But Foschini says Lamborghini has no such plans. “A smaller SUV is not consistent with the positioning of our brand,” he says. “It’s not what we need in our portfolio now.”

It’s unclear exactly when Lamborghini will become an all-battery-electric brand. Foschini says that the Italian automaker is working with Volkswagen Group partner Porsche on e-fuel, synthetic and renewably made gasoline that could presumably extend the brand’s internal-combustion identity. But now, e-fuel is very expensive to make as it relies on wind power and captured carbon dioxide.

During Monterey Car Week in 2023, Lamborghini showed the Lanzador , a 2+2 electric concept car with high ground clearance that is headed for production. “This is the right electric vehicle for us,” Foschini says. “And the production version will look better than the concept.” The Lanzador, Lamborghini’s fourth model, should arrive in 2028.
