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.

You hear about it here and there.

A triathlete riding his bike suddenly suffers life-threatening distress. A golfer has a heart attack while golfing. A young athlete, perfectly healthy, collapses on the court. Famously, trainer Bob Harper of The Greatest Loser fame, had a massive heart attack while lifting weights and is only alive today because a doctor happened to be there to perform CPR.

These stories appear periodically in the news, or someone you know tells you about something they heard along these lines. Most often, the cause is heart-related, and generally any pre-existing heart issues were previously unknown. (Bob Harper was unaware of his genetic history of a cholesterol abnormality.)

In the last year or so, I’ve been thinking a lot more about my own potential sudden demise while working out. I mean, it could happen, right? This is a first for me. Obviously, suffering a heart-related incident is a risk of exercise of which I am well aware — in my line of work you have to assume it could happen at any time to any of your clients. I was CPR-certified for many years and kept an AED in the training facility because it is that much of a risk. There has never been an issue in all these years, for which I am so grateful!

But, until now, I’ve never worried about it for myself. It only dawned on me a few months ago that I’m now at an age where this is something that might behoove me to consider. (As an emphatic reminder, regardless of your age, if you have never worked out or done any kind of intense activity, you should always consider your heart and lung health prior to starting a workout program!)

Why is this coming up now? I think as a normal process of aging we begin to think and feel differently about our own capabilities. Yes, I’m older, and perhaps no longer can I take for granted how much more our younger bodies can handle. Also, I’m ramping up intensity in cardio after some downtime. (Peloton is a wonderful workout but it asks a lot of your cardiovascular system!) And, in this last year I have witnessed so many who have lost loved ones to illness/incidents or have been diagnosed with random serious health issues that seemed to come out of nowhere.

Anything can happen at any time, and it does.

And then there is my own significant family history of heart issues that I remined blissfully unaware of until, five years ago, when my mother found herself in the ER in India after two days of “indigestion,” which was diagnosed as myocardial infarction — one artery fully blocked. Turns out both of her brothers and her father have had heart issues; I was subsequently informed by my cousin!

Between that and my vegetarian, teetotaling, mostly organic, non-GMO-food-eating father dying of stage four colon cancer less than two months post-diagnosis, I now think a lot differently about my own mortality! It’s not that I don’t take good care of myself, I do. But so did my parents . . . .

These experiences can make you think more about what you and your body, which we all tend to take for granted, can truly handle. Perhaps this same awareness makes you take a little better care of this precious body in which you reside, the only one you’ve got.

Let’s review how you can best care for yourself while still allowing yourself a good and challenging workout.

1. Be not afraid. Exercise will always improve your overall health, wellness, quality of life and yes, longevity. There are risks of injury and death inherent in exercising, yes. But getting in your car every day also carries risk, and we still drive regularly. Work out smarter, not harder.

2. Exercise is inherently stressful, depending on your choice of programs. Biking will be harder on your body than gardening but will provide greater overall benefits. Lifting heavier weights provides greater muscle development and strength gains than lifting lighter weights. Any movement is good movement, regardless.

3. Get checked out by a medical professional prior to starting or restarting and exercise program, especially if you are sedentary or older (older means if you have any doubts at all about how you might react to challenging your body with exercise). It’s true they cannot completely rule out something happening at some point. But it provides a good foundation and some peace of mind.

4. Start with minimal intensity. Shorter duration of activity, less resistance, slower movement. Your body needs to understand you will be asking it to do more, but not so much that it puts you over the edge where it can’t keep up. There are so many benefits to exercise at any level of intensity, so err on the side of caution.

5. Know and listen to yourself. If you don’t feel right, or you feel sick, or you are having trouble catching your breath, you must listen to your body. Don’t push through, or say to yourself, “I’ll just finish this workout” or ignore the signals. When in doubt, back off.

6. Take a step back if necessary. If you’ve taken a week off, or aren’t feeling 100%, or are distracted, it’s okay to do less or lift lighter or choose a different kind of activity for that occasion. Our bodies don’t function optimally all the time, and our workouts don’t need to be the most challenging or intense every time. Your physical and mental health will thank you!

7. Find an experienced coach. This works both ways — a good coach will push you but also offer objectivity in how much you should and shouldn’t challenge yourself. We can all use perspective, guidance and support.

As a natural consequence of aging, your body simply cannot function as optimally as it used to. Even if you’re in the greatest shape, you must make concessions to being older that you didn’t have to do when you were younger. Nor can you ever go wrong at any age being aware of the inherent risks of exercise and taking action to mitigate those risks.

Few of us, including me, probably need to worry about dropping dead during a workout. But if doing so makes us care for our own health and well-being more conscientiously and carefully, then a little awareness of our own mortality can be a positive force!

The benefits of physical activity are well recognised, but it’s not always easy to find time to work out during business hours.

Some workers in China are doing their utmost to break the sedentary lifestyle that comes with office life by improvising mini-workout sessions between meetings.

This practice has been gaining ground in China since a photo was posted in early July (2024) on the popular Xiaohongshu platform, according to the South China Morning Post.

The picture shows a woman flexing her biceps, with the help of a heavy tote bag and a plastic bag containing a takeaway meal, while she waits for the elevator.

“Office workers have their own gym,” the caption reads.

China’s social networks are brimming with testimonials from employees who are improvising little exercise sessions during their working day.

Some run to their company premises, while others use their office chairs to do Pilates exercises.

Everyone has their own solution to help them get moving more, and above all, maintaining their health.

While the benefits of exercise are well documented, many workers in China complain that they don’t have the time for regular physical activity.

This is due to the “996” system, which involves working from 9am to 9pm, six days a week.

In other words, they work 72-hour weeks, even though Chinese law stipulates that the working week must not exceed 40 hours.

This unbearable pace encourages a lack of physical activity and a sedentary lifestyle.

Short workout sessions in the workplace are a good way to reverse this trend.

After all, it’s a proven fact that all physical activity contributes to staying in better shape for longer, even if a certain amount of more vigorous exercise – in terms of duration and intensity – is needed to compensate for the harmful effects of a sedentary lifestyle.

But that’s not the only advantage of exercise: it also helps reduce stress and increase productivity.

Research from 2015, carried out by the Paris-based Goodwill management consultancy at the request of the Movement of the Enterprises of France (Medef, the largest employer federation in France) and the National Olympic Committee of France, maintains that a sedentary employee who takes up a physical and sporting activity improves their productivity by 6% to 9%.

In this context, companies would do well to allow their employees to get some exercise in the workplace.

But only a handful of companies have actually implemented such measures.

In the meantime, health-conscious employees can make small changes to adopt a more active lifestyle without too much effort, exercising whenever they have five minutes to spare at the coffee machine or elsewhere. – AFP Relaxnews
