MAHA Commission promotes fitness as a vital sign for children. What does that mean?
Nobody’s against fitness for children. But health secretary Robert F. Kennedy Jr.’s proposal to make physical activity a “vital sign” akin to blood pressure or growth is raising questions among physiology experts.
Physical fitness for all and children’s health are two tentpoles of Kennedy’s Make America Healthy Again mission, articulated in the MAHA Commission’s initial meeting in May, outlined in a draft Make Our Children Healthy Again report in August, and solidified in the full report Tuesday. The report promotes “physical activity as a vital sign,” a concept that usually defines a healthy level as 150 minutes of movement per week.
The commission, though, urges states to establish specific metrics of fitness, for example, a “predicted VO₂ Max” as a baseline for evaluating Medicaid managed care organizations on how much they were improving health. Other factors would include sleep, nutrition, and potentially “select high-quality supplements.”
And decades after President John F. Kennedy introduced it, the Presidential Fitness Test will return to gauge the speed and strength of America’s schoolchildren, the report says.
When the test was introduced in the 1960s, people worried that kids were spending too much time indoors, sitting around and watching television. To jump-start their fitness, physical activity at school was encouraged with routines from running to rope climbing, culminating in an annual test.
STAT has requested comment from the Department of Health and Human Services, which directed inquiries to the White House, asking about the basis for these ideas and what might come next.
What is VO₂ max, anyway?
Experts told STAT they were puzzled by the mention of VO₂ max as a metric. VO₂ max stands for the maximum volume of oxygen the body can take in and use in a single minute during intense physical activity. It’s determined by a standard exercise stress test that measures breathing with a mask to calculate oxygen consumption to define fitness.
As a measure of cardiorespiratory fitness, higher is better. It’s less clear whether it makes sense to apply an adult athlete’s numbers, aka VO₂ max, to children at play.
“It’s a really great test. It’s not really something you can do in someone under 9, 10 years old in a really good way,” Jared Hershenson, a pediatric cardiologist who directs cardiac exercise and rehabilitation at Children’s National Hospital, told STAT. “If you’re talking about trying to measure someone’s fitness who’s younger than that, there really is not any objective test that can do that, or quantitative test that can be done.”
VO₂ max is difficult to measure, even for adults, I-Min Lee, a professor of epidemiology at the Harvard T.H. Chan School of Public Health who studies the role of physical activity in preventing chronic diseases, also told STAT. You need lab equipment and you need participants to exercise to the point of exhaustion. Picture people on an exercise bike or a treadmill, going full out while wearing a mask to track their oxygen levels. Many people won’t or can’t do that, she said.
There are predictive equations that do not rely on lab tests, but instead use age, sex, body mass index, or other numbers. With varying degrees of accuracy, they are more feasible in large numbers of people to advance health.
Lee underscored that physical fitness and physical activity are related, but not identical constructs. Activity is something we do; fitness is a physiological construct.
There’s this catch: Fitness can be improved by regular activity, but it’s also partially genetically determined, she said. “I could exercise to death, but I will never be as fit as Lance Armstrong, since I don’t have his genes.”
Outside the lab, VO₂ max is familiar to weekend warriors who upload their runs, swims, rides, and hikes to sports/social media sites like Strava to track training and add up kudos from their friends. That less-than-lab-quality number is derived from heart rate and other data collected by the watches on their wrists, made by Garmin or Apple or Coros, among others in the burgeoning market for wearables.
In June, Kennedy predicted wearables for all in the next four years, but later pulled back, saying in a statement to Axios that “they are not for everyone because of concerns like cost and personal privacy.”
Eric Topol, a cardiologist and geneticist at Scripps Research Institute, scoffed at measuring VO₂ max in kids when for adults, studies have shown there are more practical ways to measure fitness that don’t involve lab testing or expensive wearables.
“To do that in children? Are you kidding me?” he said in an interview. “That is just absurd. But that’s just the anti-science movement that keeps spewing out things that are not substantiated or possible or likely.”
Topol himself gets his VO₂ max data on his iPhone, but acknowledges its limits compared to a physiology lab. For children, it would make more sense to give them a wristband with a pedometer to measure activity. “Let’s go with something simple and cheap like that, that everybody could have,” he said.
We’re not there yet for children’s wearables, Hershenson said, while acknowledging its potential if government and private sector entities work together. There are no reliable fitness data from wearables in pediatric patients, for the children Hershenson’s center sees who have significant challenges or for healthier kids. Companies on their own might have variations in how they measure fitness.
“In any of the technology, as far as I know, nothing’s been correlated with exercise tests. You’d have to have some sort of standard testing to compare it to,” he said. “I think it’s going to have to be some sort of surrogate,” maybe heart rate recovery, which tracks how fast the heart rate returns to its normal resting state after exercise.
Presidential Fitness Test, redux
Then there’s the metric President Trump wants to bring back to life: The Presidential Fitness Test. Started in the 1960s by President Kennedy and modified decades later by President Obama, it sent schoolchildren racing the mile and doing situps, pushups, pullups, and rope climbs. The new report says HHS and the Department of Education will partner with the President’s Council on Sports, Fitness, and Nutrition to help states and schools reintroduce it.
Hershenson isn’t sure measuring how many pullups a child can do is going to help gauge fitness, strength, or flexibility as they pertain to future health.
“I think it’s useful to have some sort of baseline. But you need to know what to do with that,” he said. “We’re not just gonna throw a ball around. Let’s find ways that we can improve this person’s strength and this person’s fitness by doing stuff that’s fun.”
That also means thinking about barriers to exercise.
“To me the best approach is always treating each person individually to figure out how I can help them be the best version of themselves,” Hershenson said. “That’s extraordinarily difficult when you’re making massive public policy for however many millions of people, but I think it’s going to be different for everybody.”
“Is it a questionnaire? Is it measuring heart rate recovery? Is it measuring how many steps you take?” he asked. “It’s probably not going to be perfect.”

Books are getting Australians into the gym and keeping them there longer, and the benefits of this emerging health trend aren’t just physical – they’re mental too.
Listening to audiobooks and podcasts helped Yvonne Kong, 41, and her husband get back into fitness after becoming parents and lose a combined 50 kilos.

It also helped them broaden their minds and carve out a bit of “me time” in our busy modern world.
Audiobooks and podcasts have given Aussies the chance to turn exercise into a vehicle for learning, training their minds and bodies simultaneously. Some are even taking their e-readers and paperbacks to the gym (more on that later).
“Listening to a story while working out actually helped me stay motivated and more consistent,” Kong told nine.com.au.
Like many Aussies, she used to dread hitting the treadmill and constantly found herself counting down the minutes until her session was over.
That changed when she hit play on a true-crime podcast during a workout.
Kong got so caught up in the story she forgot about the timer on her treadmill until her workout was over.
“I did an hour treadmill course and actually finished it without noticing,” she said.

Since then, she’s found herself looking forward to exercising because it gives her an hour of dedicated listening time.
Her husband does the same while running; he took up listening to audiobooks because it motivated him to run longer and more often so he could get through the story.
The benefits of reading/listening while exercising
About one in three Aussies now listen to audiobooks when they exercise, according to data from Audible.
More than a third of them exercise for longer because of it, one quarter work out more often, and half experience better mood during exercise.
Data released exclusively to nine.com.au revealed both men and women reported these positive experiences at an almost identical rate, despite often having different workout routines and attitudes towards exercise.
Audiobooks are particularly popular with runners, more than a third of whom say they feel more focused on their run while listening.
Personal trainer Ben Lucas is one of them; he started listening while running to make time pass quickly and train his mind as well as his body.
“You’re out there anyway, so you may as well be learning something valuable while you do it,” he told nine.com.au.
What the experts think
Mindfulness expert Luke McLeod told nine.com.au there has even been some research into how exercise increases blood flow to the brain, which helps information retention.
Lucas devours business and personal development audiobooks like Atomic Habits by James Clear while working out, a trend which has become known as ‘personal development/PD stacking’.
The goal is to “double-up of some type of personal development like listening to an e-book, which works out the mind, while also working out the body,” McLeod said.
‘PD stacking’ is the new health optimisation trend, according to Luke McLeod. Luke McLeod
It’s all about optimising time in our busy world, which is particularly appealing to Aussies who are time-poor; like new parents trying to juggle work and a baby.
“When I’m with [my daughter], I’m trying to be present for her, so I’m not going to be listening to podcasts or anything,” Kong said.
“When I exercise, that’s my time.”

McLeod agreed that reading or listening while working out can be a great form of self-care for some Aussies.
The only pitfall is that not every workout is suited to it.
It’s hard to keep up with an audiobook or podcast if you’re trying to count reps while strength training, and there’s no way to read an e-book on a rowing machine.
“I find podcasts and audiobooks work best during longer, slower cardio sessions,” Lucas said.
“Whether it’s an easy run, walk, or long ride, you can relax into the session, tune out a little, and focus on what you’re listening to while still getting the work done.”
He also warned Aussies to stay aware of their surroundings and hazards like traffic, cyclists, other pedestrians, or uneven paths if they listen while exercising outdoors.
McLeod added that stacking habits like exercise and reading isn’t worth it if one interrupts the other.
Road testing reading at the gym
I’ve been in and out of the gym a lot over the last decade, jumping from strength training, to reformer Pilates, and other programs in between.
But my favourite way to exercise is to hop on a treadmill with my Kindle.
I rest it on the console, set a slight incline and a moderate speed and lose myself for an hour. No workout has ever felt faster or easier.

The pros: Focusing on what I’m reading takes my mind off the clock and get through an hour of cardio without getting bored or losing motivation.
Reading at the gym also helps me stay consistent because it’s one of the few places I can just switch off and focus on my book without interruptions, so I want to keep coming back.
That hour of dedicated reading time has also been great for my mental health because it forces me to slow down and focus on something completely removed from any stress in my own life.
The cons: It did take a few sessions to get used to reading while moving, but raising the brightness on my Kindle and setting it to a larger font really helped.
Those who prefer to listen don’t have to worry about any of that though; just download an audiobook and you’re good to go.
I also invested in a pair of noise-cancelling headphones to muffle the dance music that plays over my gym’s loudspeakers, which made it much easier to focus.

Now the only downside to reading at the gym that I sometimes hit a slump after I finish a really good book because I don’t want to hit the gym again until I find something new to read.
The verdict: It’s not for everyone, but I have found that reading at the gym has been the best way for me to stay motivated and consistent.
I feel good about taking the time to work on both my body and my mind a few times a week, and I’ve been able to check some amazing books off my ‘to be read’ list while working out.
Audiobooks make it even easier for Aussies who want to exercise without the hassle of a physical book or e-reader, or who have different accessibility needs.
RICHMOND, Va. (WRIC) — 8News got a visit from two special guests Friday to learn about the benefits of Pilates and try out some beginner moves.
8News anchors Autumn Childress and Delaney Hall were joined by Laura Mae Harper and Angie Madison with Point and Flex Pilates. The studio, which opened on Sept. 3 last year, offers a variety of classes, ranging from beginner to intermediate and advanced.
“We went through years of teaching at other places and developed this beautiful studio for them and this community, and we’re super excited about it,” Harper said.

Like every piece of gear you wear on your body day in and day out, fitness trackers are incredibly personal. The right tracker for you should be comfortable, accurate, and tailored to your lifestyle, including your preferred workouts and health goals. Do you bike, row, or strength train? Do you run on trails for hours at a time, or do you just want a reminder to stand up every hour? Do you want to wear it on your wrist or your finger, or tuck it into your sports bra?
No matter what your needs are, there’s never been a better time to find a powerful, sophisticated tool to help optimize your workouts or jump-start your routine. We test dozens of fitness trackers every year while running, climbing, hiking, or just doing workout videos on our iPads at night, to bring you these picks.
Our top choice for most people is the Garmin Vivoactive 6 ($300), which works well with Android and iOS, but we also vouch for the latest Oura Ring 5 ($399) and the budget-friendly Google Fitbit Air ($100). For more wearables, check out our guides to the Best Smartwatches, Best Smart Rings, and Best Sleep Trackers.

Best Fitness Tracker Overall
Garmin makes some of the most accurate fitness trackers on the market, and the Vivoactive 6 is the best midrange option for most people. It strikes a solid balance between smartwatch features and fitness tracking, with support for both iPhone and Android users.
Why WIRED recommends: The Vivoactive 6 is accurate, comfortable, and packed with useful wellness features without feeling overwhelming. It uses Garmin’s proprietary algorithms to power features like Morning Report and Body Battery, which provide daily insights into your sleep, recovery, and readiness. It also has built-in satellite connectivity and GPS, so you can track outdoor workouts without bringing your phone along. There’s also incident detection, which alerts emergency contacts if it detects a serious fall.
Garmin’s biggest advantage remains its free Connect platform, which enables health and fitness tracking without requiring a subscription. The company also continues to add new software features through regular updates without putting them behind a paywall.
The trade-offs: Garmin launched Connect+, a $70-per-year subscription with extras like live tracking and access to Garmin’s AI-powered Active Intelligence. Former editor Adrienne So doesn’t think most people need it, but it’s worth noting if you’re looking for a completely subscription-free experience. The Vivoactive 6 may also feel like overkill for casual users who only want basic activity and sleep tracking.
