Vaping Could Make Young Adults Physically Weaker

MONDAY, Sept. 9, 2024 (HealthDay News) — In exercise bike tests, twentysomethings who’d been vaping for at least two years had much lower exercise capacity than those who didn’t, and the losses were equal to those of folks who’d spent a similar amount of time smoking.

The vaping young adults “found it harder to breath, their muscles became more fatigued, and they were less fit overall,” said study lead author Dr. Azmy Faisal of Manchester Metropolitan University in the U.K.

“In this regard, our research indicated that vaping is no better than smoking,” said Faisal, who presented the findings Sunday in Madrid at the annual meeting of the European Respiratory Society (ERS).

According to Faisal, it’s long been known that the use of e-cigarettes “is linked to lung inflammation and damage, and harmful changes to the blood vessels.”

But for young smokers, could a switch to vaping still be healthier? In an ERS news release, he said the jury is still out on that.

“We don’t yet know what longer-term vaping use does to our bodies,” he explained.

To help find out, the Manchester team recruited 60 people in their 20s, all of whom appeared to have normal lung function based on standard tests.

Twenty neither vaped nor smoked, 20 had vaped for at least two years and 20 had smoked for at least 2 years.

Each participant was subjected to exercise tests on a stationary bike, with the intensity of the exercise increased until each person reached their maximum.

Heart, lung and muscle responses were monitored. Artery function was assessed via blood tests and ultrasound.

Some differences were easily gauged. For example, the smokers and vapers visibly got out of breath even before they reached exercise capacity, and long before participants who neither vaped nor smoked.

Vapers’ and smokers’ legs also got fatigued earlier during exercise. Blood tests typically showed high levels of lactate (a sign of muscle fatigue) before they reached top capacity, the researchers said.

Blood tests and ultrasound scans also showed reduced blood vessel performance among the smokers/vapers compared to folks who had neither habit.

In measurements of exercise capacity, vapers and smokers scored about the same, with capacities topping out at 186 watts and 182 watts, respectively. That’s compared to the average 226 watt maximum exercise capacity seen among the never-smokers/vapers.

Finally, average oxygen consumption among exercising vapers and smokers was much lower than that of never-smokers/vapers, at 2.7 litres per minute, 2.6 litres per minute and 3 liters per minute, respectively.

 “In this study, we looked at a group of young people with no apparent signs of lung damage,” Faisal said. “Among the people who had been vaping or smoking for at least two years, we saw important differences in how well they coped with exercise.”

Dr. Filippos Filippidis is chair of the ERS Tobacco Control Committee and a reader in public health at Imperial College London. He wasn’t involved in the study.

According to Filippidis, “although it’s always a challenge to know if the associations we find in these studies are causal or a result of some other systematic differences between groups, people who vape need to be aware that using these products could make them less fit and able to take part in exercise. Doctors and policymakers also need to know about the risks of vaping, and we should be doing all we can to support children and young people to avoid or quit vaping.”

Because these findings were presented at a medical meeting, they should be considered preliminary until published in a peer-reviewed journal.

Hawaii fitness center combats Parkinson’s with exercise

HONOLULU (KHON2) — A local fitness center specializes in preventative training programs targeting a disease that impacts our kupuna.

Fitness Therapy Hawaii specializes in step-by-step preventative training programs targeting Parkinson’s symptoms.

In the program, patients get a clearance with doctors, work with physical therapists and prescribed medication.

“Science shows that once you get diagnosed as soon as possible, right? What exercise will do is help you keep those neurons firing, because Parkinson’s is a neurodegenerative disease. The longer you wait for these patterns of movement, you will die,” George Ma, Fitness Therapy Hawaii owner, said.

According to Yale Medicine, exercise is an essential component of Parkinson’s disease management, saying “high-intensity exercise induces brain-protective effects that have the potential to not just slow down but possibly reverse the neurodegeneration associated with Parkinson’s Disease.”

“When you get diagnosed with Parkinson’s, in the beginning, you have no hope. And then you come here, you do your tour, there’s hope. And then as they start moving through our exercise programs, they find purpose. And we have clients who have been with us for seven years at stage one,” Ma said.

Fighting the disease thats way might be intimidating to some… that’s why Fitness Therapy Hawaii lets caretakers work out with their loved ones.

Group classes are also available, which encourage socialization for what can be an isolating disease.

“In Hawaii, there is a stigma for Parkinson’s, and I think having a place and having that purpose and understanding that your fellow member has been fighting it with you,” Ma said.

Walking May Not Provide Enough Exercise to Maintain Fitness

Walking May Not Provide Enough Exercise to Maintain Fitness

  • Researchers report that walking is the most popular leisure activity in the United States.
  • They note urban dwellers also like to run and lift weights, while rural residents also enjoy gardening and hunting.
  • Experts say those activities may not be enough for some people to maintain a higher fitness level, so additional exercise may be needed.

Walking is the most popular leisure activity in the United States among both urban and rural residents, according to a new survey.

Researchers reported that urban dwellers also tend to engage in running, weightlifting, and dance, while people in rural areas also enjoy gardening, hunting, and fishing.

The researchers said the differences in leisure activity choices could reflect what people have access to or what is culturally supported in certain areas. They added that urban residents were more likely to meet physical activity guidelines than people living in rural regions.

The researchers, however, noted that even among walkers, only 25% met combined guidelines for aerobic and muscle-strengthening physical activity. About 22% did not meet either guideline.

The researchers reached their conclusions by analyzing telephone survey data collected from a national sample of 396,261 U.S. adults in 2019.

They reported that 44% of respondents listed walking as the activity they spent the most time doing. The data closely matched another U.S. study from 2011.

The new findings were published today in the journal PLOS One.

The researchers said they hoped their study could help boost physical activity by encouraging people, as well as medical and fitness professionals, to tailor workouts to certain regions and demographics.

“We see a need to continue to support our partners in small towns and rural places by creating physical, social, and cultural conditions that support physical activity,” said Christiaan Abildso, PhD, a physical activity specialist at West Virginia University and a lead author of the study, in a statement.

Everyone needs to ask, ‘how does what we’re doing affect physical activity,’ in order to help get people more active, more often, in more places,” he added.

Abildso listed several steps community leaders can take to improve fitness opportunities. Among the suggestions:

  • Create a wide shoulder on a country road for cycling and running.
  • Expand the national network of rail trails.
  • Help a senior center create a chair exercise program.
  • Create or improve green spaces such as parks.
  • Keep school facilities open to the public.

“This study aligns with other studies on physical activity in the U.S. population,” said Michael Fredericson, MD, a professor of orthopedic surgery at Stanford Medicine in California. Fredericson wasn’t involved in the study.

“This underscores the continued need to encourage easily accessible forms of exercise, such as walking, or more functional activities around the home, which are more doable for folks,” Fredericson told Healthline.

There are numerous benefits to daily walking, a low-stress activity that can help people exercise with a minimal risk of injury.

A daily walking routine can also improve mood and support long-term weight management.

A 2023 review reported that walking 8,000 to 10,000 steps per day can provide substantial cardiovascular health benefits as well as psychological well-being.

Gardening can also be considered a moderate physical activity that supports weight management and helps build strength. The time outdoors in a garden can also help your body produce vitamin D, which supports bone strength, calcium absorption, and immune function.

Gardening may also support mental well-being by improving mood and reducing stress.

“Walking and gardening can meet exercise recommendations for most people if performed at sufficient intensity and duration,” said Fredericson. “Still, hunting and fishing, unless there is a lot of walking/hiking, typically do not provide adequate moderate-to-vigorous physical activity.”

The Centers for Disease Control and Prevention (CDC) recommends that adults get at least 150 minutes of moderate-intensity aerobic activity per week.

The agency suggests that exercise could come in the form of brisk walking for 30 minutes a day, 5 days a week, or 75 minutes of vigorous-intensity aerobic activity each week, such as swimming laps.

The CDC also states that adults need at least 2 days a week of muscle-strengthening activity.

David Cutler, MD, a family medicine physician at Providence Saint John’s Health Center in Santa Monica, California, recommends people try to meet these minimal time standards in their fitness routines.

“There should be greater emphasis for all adults to meet the minimum exercise guideline of 150 minutes per week,” he told Healthline.

“Their exercise routine should include more than just aerobic exercise, like walking, running, biking, swimming, or dancing. There should also be time devoted to muscle-strengthening exercises of both the upper and lower extremities. This could be as simple as using hand weights and squats.”

Agency officials note that the “exact amount of physical activity needed to maintain a healthy weight varies greatly from person to person.”

Fredericson said a comprehensive weekly exercise program should contain four main components. Those are:

He also suggested people can do “exercise snacks,” which consist of physical activity lasting 1 to 5 minutes performed periodically throughout the day. Those quick exercises can include stair climbing, brisk walking, and jumping jacks.

“This approach has demonstrated high compliance rates and can significantly improve cardiorespiratory fitness, particularly in physically inactive adults,” Fredericson said.

Cutler agrees a wide variety of exercise is the best approach.

“Individuals should supplement walking with muscle-strengthening exercises like yoga or resistance bands, and higher-intensity activities such as running, dancing, or cycling,” he said. “Effective ways to increase activity include utilizing community infrastructure like rail-trails, joining senior center programming, and creating local, accessible activity spaces.”

“Core exercises should also be incorporated in a weekly routine,” he added. “These strengthen the muscles in your pelvis, lower back, hips, and abdomen, leading to improved stability, better posture, and reduced back pain.”

“Stretching exercises are also important for health aging, injury prevention, and overall fitness,” Cutler noted. “Evidence supports that consistent stretching increases range of motion, reduces joint stiffness, and enhances vascular health.”
