‘It’s never too late to start exercising’ claim scientists

In more than a decade of work, Israeli academics took nearly 2,000 pensioners aged 70 and tested their fitness at ages 70, 78, and 85.

Those doing less than four hours of exercise a week were classed as ”sedentary” and those doing four hours were termed ”active”.

The team from Jerusalem’s Hebrew University Medical Centre and Hebrew University Hadassah Medical School found active 70- to 78-year-olds were 12 per cent less likely to die than their sedentary counterparts.

Those between 78 and 85 were 15 per cent less likely to die.

And those aged 85 to 88 were 17 per cent less likely to die.

The benefits of exercise were also found to include more independence, less loneliness and better general health.

The authors wrote: ”The clinical ramifications are far-reaching.

”As this rapidly growing sector of the population assumes a prominent position in preventive and public health measures, our findings clearly support the continued encouragement of physical activity, even among the oldest old.

”Indeed, it seems that it is never too late to start.”

The findings are published in the Archives of Internal Medicine.

Exercise beats angioplasty for some heart patients

Exercise beats angioplasty for some heart patients

Working up a sweat may be even better than angioplasty for some heart patients, experts say.

Studies have shown heart patients benefit from exercise, and some have even shown it works better than surgical procedures. At a meeting of the European Society of Cardiology on Sunday, several experts said doctors should focus more on persuading their patients to exercise rather than simply doing angioplasties.

Angioplasty is the top treatment for people having a heart attack or hospitalized with worsening symptoms. It involves using a tiny balloon to flatten a blockage and propping the heart artery open with a mesh tube called a stent. Most angioplasties are done on a nonemergency basis, to relieve chest pain caused by clogged arteries cutting off the heart’s blood supply.

“It’s difficult to convince people to exercise instead of having an angioplasty, but it works,” said Rainer Hambrecht of Klinikum Links der Weser in Bremen, Germany.

Hambrecht published a study in 2004 that found that nearly 90 percent of heart patients who rode bikes regularly were free of heart problems one year after they started their exercise regimen. Among patients who had an angioplasty instead, only 70 percent were problem-free after a year.

Hambrecht is now conducting a similar trial, which he expects to confirm his initial findings: that for some heart patients, exercise is more effective than a surgical procedure.

Other experts agreed that would likely be the case.

An angioplasty “only opens up one vessel blockage,” said Dr. Christopher Cannon, an associate professor of medicine at Harvard University and spokesman for the American College of Cardiology. He was not linked to Hambrecht’s research. “Exercise does a lot more than fixing one little problem.”

Among other benefits, exercise lowers bad cholesterol while raising good cholesterol, helps the body process sugar better, improves the lining of the blood vessels and gets rid of waste material faster. Exercise also lowers blood pressure and prevents plaque buildup in the arteries.

Previous research has estimated one third of heart disease and stroke could be prevented if patients did two-and-a-half hours of brisk walking every week. In the U.S., that would mean 280,000 fewer heart-related deaths every year.

Joep Perk, a professor of health sciences at Sweden’s Kalmar University and spokesman for the European Society of Cardiology, said two thirds of heart patients in line for an angioplasty could probably get better benefits by regularly working up a sweat.

Experts say less than 20 percent of heart patients get the recommended amount of exercise — about 30 minutes of moderate activity five times a week.

Perk said doctors who performed angioplasties on their patients without asking them to change their lifestyles were ignoring the fundamental problem. “It would be like getting rid of the most troubled rust spots on a car without doing anything to stop more rust from appearing tomorrow.”

Still, doctors admitted that persuading patients to exercise instead of simply going in for an angioplasty, which can take less than a day, would be a tough sell.

“Most patients want the quick fix,” Cannon said. Exercise may improve patients’ hearts better than an angioplasty, but it may also take months or even longer for patients to feel the benefits. “It’s a lot easier to get your artery fixed than it is to exercise every day.”

That’s a stretch: states seek to regulate yogis

yogis


Yogis are males who practice, or are mastered in, yoga. Yogini is the term used for female yogins.

Alternatively it is the name of a ficitonal bear who resides within Jellystone Park

U.S. yogis are being asked to regulate more than their breathing — and they are fighting back.

About 50 yogis gathered in New York recently to discuss hiring a lobbyist and raise funds to fight a state proposal to require certification of yoga teacher training programs — a move they say would unfairly cost them money.

“It has brought us under one roof,” said Fara Marz, who held the gathering at his Om Factory yoga studio in New York. “And this shows that yogis can be vicious, political, together.”

Yoga enthusiasts who say autonomy is fundamental to what they do are pitted against state governments eager for a slice of what the Yoga Journal says has become a $6 billion industry with yoga practiced by 16 million Americans.

The fight has underscored the difficulty of regulating yoga studios that have become ubiquitous on Main Streets and in gyms across the country without appearing heavy-handed or infringing on religious freedom.

New York’s yoga instructors first attracted the state’s attention last spring, when the education department announced training schools could face up to $50,000 fines if they did not submit to state regulation that governs vocational training. After protests from yoga proponents, the education department withdrew its plans.

Perhaps yogis can breathe easily in New York. The state legislature is considering a bill that would exempt them from vocational school certification.

“The message from the community has been loud and clear: get your government hands off my yoga mat,” State Senator Eric Schneiderman said in a statement. “Next time, the state will think twice before threatening a practice that brings so much tranquility to New Yorkers.”
