Hydrogen-rich gas inhalation can alleviate exercise-induced fatigue
A new study published in the International Journal of Sports Medicine, titled “Inhalation of hydrogen-rich gas before acute exercise alleviates exercise fatigue,” has found a possible novel intervention for exercise-induced fatigue. A cross-discipline international team of U.S. and Chinese researchers, including at Hebrew SeniorLife’s Hinda and Arthur Marcus Institute for Aging Research, has found that inhaling hydrogen-rich gas (HRG) before engaging in acute exercise can significantly reduce fatigue and enhance performance.
The research involved 24 healthy adult men who were tested for their maximum cycling power (Wmax) and maximum cycling time (Tmax). In a double-blind, counterbalanced, randomized and crossover design, participants inhaled either HRG or placebo gas (air) for 60 minutes before cycling at 80% Wmax until exhaustion.
Key findings from the study include:
- Reduced perceived fatigue: Participants who inhaled HRG reported significantly lower scores on the Visual Analog Scale (VAS) for fatigue compared to those who inhaled placebo gas.
- Improved exercise performance: HRG inhalation improved cycling frequency during the final 30 seconds of the exercise and reduced the rating of perceived exertion (RPE) at both the beginning and end of the ride.
- Oxidative stress markers: HRG inhalation showed a significant improvement in the ability to inhibit hydroxyl radicals and lower serum lactate levels after exercise, indicating reduced oxidative stress.
- Functional performance: While HRG did not significantly impact counter-movement jump (CMJ) height or glutathione peroxidase activity, the overall benefits on fatigue and oxidative stress markers were notable.
“The study’s findings suggest that HRG inhalation prior to exercise could be a valuable strategy for athletes and fitness enthusiasts looking to enhance performance and recovery. By mitigating fatigue and improving markers of oxidative stress, HRG has the potential to support more effective training and better overall health outcomes,” said Junhong Zhou, Ph.D., assistant scientist II, Hinda and Arthur Marcus Institute for Aging Research, Hebrew SeniorLife.
The study opens new avenues for exploring the benefits of hydrogen-rich gas in sports and exercise science. As further research continues, HRG inhalation may become a widely adopted practice for enhancing athletic performance and combating exercise-induced fatigue.

How much exercise is enough? A local doctor says you only need 15 minutes a day – WTOP News
Exercise is part of a healthy lifestyle and its benefits are well known and have been for a long time. What is only recently proven by doctors is just how much exercise makes a difference for one’s longevity.
By now, most people understand that exercise is part of a healthy lifestyle; its benefits are well known and have been for a long time. What is only recently proven by doctors is just how much exercise makes a difference for one’s longevity.
For most people who sit at desks or behind the wheel all day, the problem is often finding time to work out. The good news, according to Dr. Julie Chen, an internal medicine and lifestyle medicine doctor at Kaiser Permanente in Gaithersburg, is that a daily exercise routine can be broken down into brief segments.
“The general recommendation is for 150 minutes of moderate activity per week,” Dr. Chen said. “So that is roughly about 30 minutes a day, five days a week. But the important point is it does not have to all be done at once. You can break it up into shorter segments of exercise and still get the same great benefits.”
And those benefits can be tremendous. Chen said that studies have shown going from no exercise a day to only 15 minutes of total exercise a day can “can actually decrease their risk of death, death from all causes, by about 14%.”
“Any movement is actually better than being sedentary,” she said.
Movement can be divided up into short segments throughout the day instead of in one long, strenuous workout and it can still offer the same reductions in the risk of certain diseases.
Now, you might understand there are benefits of exercising for short periods of time, several times per day; but you might be wondering how you can get in the gym several times a day.
Chen advocates for what she calls “exercise snacks” — “small bursts of physical activity that you can get in, two to three minutes at a time throughout the day.”
For example, taking the stairs or doing squats while putting groceries away, walking around the office on a phone call or planking while your dinner is in the microwave. Chen said try to do whatever it takes to get a few minutes of movement in a few times a day.
Chen is also a big fan of fitness apps, including the ones that come built into our smartphones and watches: “Studies have shown that that is really motivating that you can actually track your progress in your app. You can see your trends.”
“Consistency is a really big goal of this effort, and so if you look at your trends over time, that’s going to be a really rewarding aspect of trying to improve your health,” she added.
Beginning an exercise regimen doesn’t need to be complicated or time-consuming. You don’t need to splurge on workout clothes or a gym membership; you just need a few minutes, several times a day, to start reaping the benefits.

Adults hop on viral ‘rebounding’ trend to make exercise fun again — ‘I feel like a kid’
Forget boring home workouts, on-demand HITT classes and cold winter runs.
The latest wellness trend bouncing around TikTok involves a workout you might not even realize you’re doing, and that’s the point. It’s called rebounding. This low-impact exercise involves jumping on a mini fitness trampoline — called a rebounder — to get your heart pumping and support lymphatic drainage.
On Amazon, this best-selling model is currently on sale for just $129. It measures in at just 40 inches, making it ideal for small spaces while still offering room for an adult to jump, squat and jog in place. Users swear it gives them a seriously effective full-body workout, and many remark that it’s “so much fun” to use.
Clinical trials also back the benefits: a 12-week rebounding program for overweight women showed significant improvements in body composition as well as a decrease in diastolic blood pressure.
Ready to jump on the rebounding trend, too? You’d better hop on this Amazon deal fast.
This sleek rebounder by BCAN is sturdy and easy to set up, thanks to pre-assembled bungees and simpel video tutorial.
Reviewers say it’s completely changed their workouts, with one remarking they “feel like a little kid again.” Others have also noted it’s much easier on their joints than higher-impact exercises.
“It absorbs impact well and allows for a nice, smooth rebound that is gentle on the joints, making it perfect for a low-impact cardio workout,” one person explained. “Whether I’m doing high-intensity intervals or simply bouncing for fun, the movement feels fluid and responsive.
The BCAN model features an upgraded handlebar for added stability. It’s 8mm premium bungee — with a durable woven outer layer and a 350-strand natural latex core — delivers smooth, quiet bounces, so you can enjoy your workout without disturbing others.

Fitness trainer with 18 years of experience shares why exercise is crucial for kids: ‘Not just about health and fitness’
Exercise is often spoken about in the context of physical fitness – stronger muscles, better stamina and improved overall health. But its value, especially for children, extends far beyond the body. Regular physical activity can quietly shape character, teaching lessons about effort, patience, discipline and resilience that mirror how the real world works. From learning to cope with discomfort to understanding that progress takes time, exercise can become a powerful training ground for life itself.

Chennai-based fitness trainer with 18 years of experience, Raj Ganpath – founder of the Slow Burn Method, co-founder and head coach at Quad Fitness, and author of Simple, Not Easy – is shedding light on why exercise is important for kids, with the benefits going beyond health and fitness. In an Instagram video shared on February 27, he explains how the impact of exercise extends far beyond physical wellness, shaping resilience, discipline and long-term character development.
Embracing discomfort
According to Raj, exercise is one of the healthiest ways to help children learn how to sit with discomfort in a safe, structured and sustainable way. Life inevitably brings challenges and unease – something adults understand well – but many children today are shielded from situations that test their resilience.
He explains, “Exercise is a great way to experience this discomfort in a safe and sustainable manner. Lifting weights, holding a plank, doing cardio, repping till it burns, all of these things are opportunities to embrace discomfort, opportunities to put themselves in a place where they’re not comfortable and learn from it, opportunities to practice physical and mental resilience.”
Learning hardship
The fitness trainer emphasises that hardship is an inevitable part of life, and meaningful success often requires pushing through moments of difficulty. While most adults recognise this truth through lived experience, children may not always have the same exposure to challenge. Raj believes exercise can bridge that gap.
He elaborates, “It will teach them that they need to do hard things if they want to accomplish something. Getting through a very hard workout, setting a goal and achieving it, completing a task. All of these things are not just random chores. These are incredible opportunities – opportunities to experience hardship and build fortitude.”
Delayed gratification
In today’s fast-paced world, the desire for instant gratification is stronger than ever – and children are growing up at the centre of it. With technology, streaming platforms and 10-minute delivery services, almost everything is available at the tap of a screen. As a result, the ability to wait, persist and work steadily towards a long-term goal can easily take a back seat. Exercise, notes Raj, offers a powerful counterbalance.
He explains, “Everyone wants everything right away today. This is true for us adults too, but it is even more true for our kids because this is the only world they know. A world where everything happens right then and right there, whenever they want it, wherever they want it. Exercise will teach them to wait, to be patient, to trust the process, to fail and still keep going, to work towards something larger that they will get much later. This is a very important character building quality and will serve them well for many, many years to come.”
The fitness trainer concludes, “Exercise is not just about health and fitness. It is a simulation of life itself. A ready-made character building tool available to you to help prepare your kids for life, the raw and real life that they’re going to have to deal with no matter what. So make sure they build the habit and make sure they embrace it.”
