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.

Still finding it too cold to exercise outside? 7 best advanced home workouts to boost muscle and endurance

It might be starting to feel more spring-like outside (last weekend, we thank you), but March is still pretty cold at times, with more than its fair share of inclement weather. So, if you’re still leaning towards living room workouts rather than lacing your trainers up for a chilly run, we get it.

While there are a myriad of advantages to getting your movement in from home (convenience, cost and time, to name just a few), it’s easy to write off a home workout as too easy. And all too often, they’re targeted at us getting back into movement post injury, rehab or baby. Which got us thinking: is it really possible to do an advanced workout from home?

How to get rid of flabby arms?

Per the fitness coach, the one exercise that can help you get rid of flabby arms is dumbbell bicep curls with a twist. The video begins with Patrick sharing tips on how to do the exercise and its variation. He suggested starting with light dumbbells, weighing approximately 7-10 pounds and focusing on perfect form – “Keep your elbows locked at the side and move slowly (3 seconds up and 3 seconds down).”

“As you progress, increase the weight to challenge your muscles. You should feel the burn. If you want variety, you can also try hammer curls, but this time, use the 21’s Strategy – 7 reps lower half, 7 reps upper half, and then 7 full range – 21 in total. Superset this with tricep dips or extensions to tone up the back of those arms, and then you will say goodbye to that flab in no time,” he suggested.

How to do 21’s for bigger biceps?

The coach also suggested how to do the 21’s Strategy correctly to up your game and feel the burn. “If you’ve ever tried 21’s for biceps and didn’t feel the burn…you probably did them wrong,” he wrote. Here’s how to do them properly:

The Breakdown

21 reps total > 3 phases > No ego lifting

  • First 7 reps – Lower half of the curl (bottom to halfway)
  • Next 7 reps – Upper half of the curl (halfway to the top)
  • Final 7 reps – Full range of motion (all the way up and down)

Tips to keep in mind:

  • Use control, don’t just swing the weight.
  • Keep elbows locked, no cheating with shoulders.
  • Choose a lighter weight than your usual curl, or you’ll burn out fast.
  • Do this exercise 1-2 times a week, especially if you work out at home.

Remembering Red Lerille

Remembering Red Lerille

“Hello, goodbye, and toilet paper.”

According to Lloyd “Red” Lerille, owner of Red Lerille’s Health & Racquet Club in Lafayette, Louisiana, those are the three most important things in business. Considering his successful 63 years in the health and fitness industry and his induction into the HFA’s inaugural Hall of Fame class, it’s hard to argue with his wisdom.

From Humble Beginnings to Industry Pioneer

Red’s journey began as a three-time high school wrestling champion in New Orleans. Inspired by his uncle Harold, Red saw fitness as transformative. In 1953, he trained at Ajax, Joe Gold’s New Orleans gym, honing his skills in bodybuilding and business. He began competing in contests and won the Mr. America title in 1960, before serving a stint in the Navy.

“When Red got out of the Navy, Mike Stansbury had him manage his gym in Lafayette,” recalls Red’s daughter Kackie Lerille. “He came with a bag of clothes and a unicycle. All he ever wanted was to own a little gym like that.”

With a $200 loan from his father, Red and his wife, Emma, opened Red Lerille’s Health & Racquet Club, a 3,500-square-foot gym in Lafayette, in 1963.

“The first club was small. We joke it was the size of a racquetball court,” says Kackie. “It was really a labor of love. My dad built his own equipment because you couldn’t buy any.”

He eventually moved to his current location in 1965, upgrading to 4,000 square feet. But, as with bodybuilding, staying small was never part of the plan. In 1968, Red made his first addition, adding a vinyl pool. There was no going back.

“Red decided early on he was going to reinvest in the club and do something new every month,” says Mark Lerille, Red’s son, who now manages the property. “It didn’t matter if it was something small or something that would take time to finish, he was going to do something every month.”

It’s a tradition that continues to this day.
