Asparagus extract shows synergistic effects with exercise for improved heart fitness

Researchers in Thailand explored the effects of Asparagus officinalis supplementation alongside HIIT to investigate whether the two could work synergistically.

They reported that the combination “has the potential to improve cardiovascular and respiratory function and serve as a preventive strategy against cardiovascular and respiratory disorders in obese and overweight individuals.”

Botanical extract for cardiovascular health

High-intensity intermittent training (HIIT), which involves short bursts of intense exercise and recovery periods, has been found to improve muscle performance and cardiopulmonary fitness. However, little research has evaluated its impact on cardiovascular and pulmonary function in obese individuals, according to the researchers of the new study.

Ecdysteroids (arthropod steroid hormones) have demonstrated anabolic, fat-reducing, anti-inflammatory and cardioprotective properties, and 20-hydroxyecdysone (20E), which comes from Asparagus officinalis, has been shown to improve physical performance and muscle strength in healthy populations.

Previous studies have found that 20E supplementation reduced body weight, fat, cholesterol and inflammation, and improved muscle strength and bone health in obese individuals. However, the researchers noted that no previous studies have explored the combined effects of HIIT and 20E supplementation on cardiovascular and pulmonary function in obese and overweight individuals.

Learn more at the Active Nutrition Summit

From June 23-25, industry leaders, researchers and innovators will gather in Vienna, Austria, for three days of cutting-edge insights, dynamic discussions and engaging networking opportunities.

The three-day summit will offer a one-stop shop for the latest must-have insights in the world of active nutrition and will cover the state of the market, essential insights on marketing, regulation and social media, mind health, personalization, the female athlete and many more topics. Take a look at our program to learn more.

Study details

The researchers recruited 72 obese and overweight male and female participants between the ages of 18 and 30 with a BMI over 22.9 kg/m². They were randomized into four groups: the control group, the HIIT group, the AOE (A. officinalis extract) group which received 1.71 mg/kg/day, and the combined HIIT and AOE group. The HIIT Program consisted of three sessions a week, and participants in the AOE and HIIT and AOE groups received capsules and logged their intake twice daily via an app.

The researchers assessed heart rate (HR), HR variability, endothelial function, blood pressure (BP), BP variability, pulmonary function and volume, respiratory muscle strength, chest expansion and body composition at the beginning of the trial and 12 weeks post-intervention.

Results indicated that combining HIIT with 20E supplementation improved heart rate variability, endothelial function andexpiratory muscle strength after 12 weeks, which in turn was found to benefit lung function and exhalation.

While the 20E group did not experience any significant changes, the researchers suggested that 20E can support molecular pathways related to protein synthesis, inflammation reduction and cardiovascular protection. These effects were more pronounced in the HIIT and AOE group, where the systems activated by the exercise potentially allowed 20E to further improve muscle remodeling, vascular function and autonomic regulation.

The HIIT and AOE groups also showed increased blood flow and enhanced vascular responsiveness, and in comparison to the HIIT group, they showed improved vasodilation, allowing for increased blood flow to tissues. The 20E group did not display significant signs of improved endothelial function.

Resting blood pressure (BP) significantly decreased only in the HIIT group, however, the researchers noted that 20E appeared to reduce BP variability further when combined with HIIT, “suggesting a synergistic effect that may help reduce BP variability”.

“A 12-week HIIT program combined with A. officinalis extract supplementation improved HR variability indices, potentially lowering cardiovascular disease and atherosclerosis risk via increased endothelial function,” the researchers concluded.

“It also enhanced expiratory muscle strength, lower-chest wall expansion and, consequently, pulmonary function. The clinical implication is that utilizing HIIT in conjunction with supplementation with A. officinalis extract containing 20E at 1.71 ± 0.24 mg/kg/day daily for 12 weeks is safe and could be an option for individuals who are obese or overweight.”

They added that future research should assess blood lipid profiles, blood glucose levels and inflammatory markers in order to gain a better understanding of the mechanisms of action.

This simple strength training trick builds more muscle and better technique—here’s how to try tempo training in your next home workout

Of all the exercise techniques I use when training clients (and myself), slowing down the movements is one of my favorites. And I’m not the only fan.

“Tempo training is excellent because it increases time under tension,” says Steven Chung, physical therapist at VSI Spine Solutions in Reston, Virginia.

Snap Fitness Sittingbourne Gym helps young people get into exercise

Exercise should be a vital part of all of our lives, particularly young people.

There are a host of benefits that it can provide, including improved physical health, better mental wellbeing, increased confidence, stronger social connections, improved focus and discipline, and the development of healthy lifelong habits.

Exercise can also help to reduce crime rates by giving young people better structure, a clear routine and a sense of purpose.

.

All in all, it helps create positive outlets for energy, builds responsibility and encourages stronger community connections.

That’s where Snap Fitness in Grid House, St Michael’s Road Sittingbourne comes in.

The gym offers memberships for young people aged 16 and above.

..

It also works closely with local youth groups and sports teams that use the gym, including Sports Connect, Westlands Secondary School, Sittingbourne FC youth teams, Iwade Herons FC and Faversham Strike Force, supporting the community and providing youngsters with the opportunity to stay active.

Jack Smith of JS Performance Training and Alex Palmerton of Palmo Fitness also work with younger children from the age of five upwards.

Some simply want to improve their overall fitness, while others are focused on improving performance in their chosen sports. Between them, they support academy footballers, professional and amateur boxers, basketball, cricket and rugby players, helping young athletes build strength, confidence and discipline from an early age.

Try the windmill exercise and thank me later – it ‘targets your obliques from every angle’ and improves core strength more than Russian twists

The Russian twist is one of the most popular core exercises, and it’s a good option for improving core strength. However, the windmill exercise is a functional movement (so it mirrors real life) with a safer movement pattern for most people. It could be a better option.

It’s an advanced move, but one well worth doing if you want an alternative in your strength training routine or to build strength and stability specifically in the muscles along the sides of your core, known as the obliques. Doing so can better help you in daily movements, such as bending to the floor to reach objects on the ground or to play sports like tennis. If you’re a fan of a bodyweight Pilates workout, you’ll find your practice gets easier after doing this exercise for a while.
