Silver Yoga Improves Fitness in Seniors

While the benefits of performing yoga have long been discussed, it can often be an intimidating form of exercise to try. Some people picture a studio full of perfect-looking twenty-somethings who can contort their bodies into all kinds of interesting positions. Some people are afraid they might look silly if they don’t know what to do or they are simply afraid of injuring themselves if they try to bend this way or that.

As most people age, they start to lose balance and flexibility, among other indicators of physical fitness, making it even less likely that they would attempt an activity like yoga that involves stretching and holding poses for certain lengths of time. Recently a group of researchers in Taiwan developed a type of yoga exercise program that they’ve named “silver yoga.”

This program, developed by Chen, Tseng, and colleagues (2), consists of four phases:

  1. 20 minute warm-up of eight poses to loosen up the body;
  2. 20 minutes of hatha-style yoga in which seven gentle stretching postures are performed;
  3. 10 minutes of relaxation in which three activities to rest the body are performed; and
  4. 15 minutes of guided imagery to facilitate relaxation.

This program was critically reviewed by experts in the fields of yoga, elderly exercise, geriatric nursing, geriatric physical therapy, osteopathy, sports physiology, sports medicine, and/or sports injuries (2).

In a study published in Nursing Research, Chen, Fan, and colleagues (1) studied a group of 55 participants aged 65 or older who participated in 24 weeks of a three time per week silver yoga exercise program. Measures of body composition, cardiovascular-respiratory function, flexibility, muscular power and endurance, balance, and agility were taken before the study began, at twelve weeks, and at 24 weeks.

At the end of the study, participants in the silver yoga group had significantly reduced body fat percentage, decreased respiration rate (indicating that the exercise took less effort, and improved shoulder range of motion (right shoulder abduction) compared to their pre-silver yoga measurements (1). Additionally, the silver yoga group had improved in all measured physical fitness categories when compared to the control group at the end of the 24 week study.

As the general population ages, it’s becoming more important than ever for senior-based health programs to be developed and implemented to keep our seniors healthy and reduce the burden on the healthcare system. A silver yoga program is just one of many exercise options for older adults to participate in to positively affect their health. The importance of the above study is that it shows that exercise programs tailored specifically to the abilities and needs of an older population can, in fact, improve their overall physical health.

Some exercise is better than none for lowering heart disease risk

Exercise advice for couch potatoes usually goes like this: doing something is better than doing nothing. Turns out that might be true–people who do even a little regular exercise may have lower risk of heart disease than people who never leave the sofa.

Researchers did a meta-analysis of 33 studies looking at the effects of exercise on coronary heart disease among people who were active or sedentary to see if they could quantify how much exercise was needed to show any benefits. The 2008 Physical Activity Guidelines for Americans, which recommend a minimum of 150 minutes a week of moderate exercise for health benefits, were used as a measure.

People who met those basic guidelines had a 14% lower risk of heart disease compared with people who did no leisure time physical activity. Bigger benefits were in store for people who exercised 300 minutes a week–their heart disease risk was lowered by 20%. There were diminishing returns for those who were active at five times the basic guidelines; they saw only a 25% decreased risk for heart disease.

But people who did less than the recommended 150 minutes per week also had lowered risk of heart disease compared with their sedentary counterparts.

When grouped by gender, women fared better than men, seeing reduced heart disease risk overall.

While the U.S. guidelines seem to be a good marker for exercise, the study authors note that more research may be necessary to further explore the relationship between physical activity and heart disease risk.

The study was released Monday in the journal Circulation.

Jogging Fights Beer Belly Fat Better Than Weights

Weight training is touted as the cure for many ills. But if the goal is to lose belly fat, aerobic exercise is the only way to go, exercise scientists say.

We’re not talking about muffin tops, the annoying bit of pudge that rolls over a woman’s waistline and is featured in those strange Internet ads. Rather, this is gut fat lodged around internal organs, which could look like a beer belly from the outisde. It’s considered a risk factor for diabetes, heart disease, and cancer.

Surprisingly little research has been done comparing the health benefits of strength training with weights to aerobic exercise such as walking. But that’s just what researchers at Duke University did.

They compared changes in visceral fat – the fat that wraps around internal organs – in people who did strength training compared to a group who did aerobic exercise. They divided 198 overweight, sedentary adults into groups, with one group working out with weights three times a week for eight months. A second group jogged 12 miles a week.

The aerobic exercisers lost significant amounts of visceral fat, as well as fat around the liver. They also lost abdominal fat overall, and had improvements in liver enzymes and insulin resistance. By contrast, the people who were pumping iron lost a wee bit of subcutaneous fat, but their stats otherwise didn’t improve. The aerobic training burned 67 percent more calories than resistance training. The results were published in theAmerican Journal of Physiology.

“Resistance training is a very good way to increase lean muscle,” Cris Slentz, an exercise physiologist at Duke who led the study, told Shots. “And aerobic exercise isn’t.” But if the goal is to lose fat, then aerobic exercise is the ticket, he said.

There’s no easy way to know how much visceral fat a person has; the researchers had to put people in CT scans to measure it. But one good clue is a beer belly. And men tend to carry more visceral fat than women, Slentz says, while white people tend to have more visceral fat than African Americans. And older people tend to internalize fat, while younger people carry fat right beneath their dewy skin.

Fitness Tips: Back stretch helps tighten abs

Back Stretch Helps Tighten Abs

When it comes to training your abdominal muscles, it’s good to introduce new moves into your routine so you continue to “surprise” your muscles. Otherwise there’s a tendency for them to go on autopilot and you won’t get the maximum benefit of your efforts.

Sit upright on a flat, padded surface or mat with a small inflatable ball or firm pillow behind your waist. Place your feet hip-width apart with your knees bent and feet flat on the floor. To begin, place your left hand behind your head and your right hand behind your right thigh. On an exhalation, push your lower back against the ball and raise your right leg. Pause with your shin parallel to the ceiling.

Inhale as you roll back and extend your right leg. Remember to keep your abs contracted by pressing firmly against the ball or pillow. At first, just roll back halfway, and you don’t need to fully straighten your leg. Pause for 2 seconds, then exhale and roll back up to the start position. As you get stronger, place both hands behind your head and roll back a little more. Do 12 to 16 repetitions, then switch sides and repeat.

Fitness Tips: Curls for the well-armed

Curls for the well-armed


Use light weights in this exercise for a convenient, fast and effective way to work the fronts and backs of your arms at the same time. Remember to pull your abdominal muscles in to support your spine in this forward bend.

Stand with your feet about shoulder-width apart. Grasp a pair of 3- to 5-pound dumbbells, bend your knees slightly and lean forward so your torso is almost parallel to the floor. Keep your elbows next to the sides of your torso. Straighten your right arm behind you until your elbow is straight and next to your body. Simultaneously, bend your left arm to bring the dumbbell close to your left shoulder. Pause for 2 seconds in this position.

Repeat the same movement again, but this time straighten your left arm behind you and bend your right arm forward. Continue to alternate arms until you have completed 32 biceps curls and 32 triceps extensions with each arm. Focus on keeping your upper arms close to your torso as you perform this move. Stand up, rest for 15 seconds and repeat two more sets.

Army Steps Up Efforts to Get New Troops Fit

Shape Up, Soldier!

Soldiers can still find pancakes on the chow line at the U.S. Army’s Fort Leonard Wood training facility in Missouri. But now they’re made with whole-grain batter — adding more fiber and protein.

The new focus on nutrition is part of a ‘Fueling the Soldier’ initiative that aims to teach soldiers to make healthier choices during military training and in combat.

 

“The Army must treat our soldiers as tactical athletes to improve not only physical training but also trying to get them to adapt the right nutritional aspects to help prepare them for the battlefield and for their life,” Lt. Gen. Mark  Hertling said in a statement.

Hertling is overseeing an overhaul of physical readiness training. In fact, the Army is tossing out the old training manuals, and taking a new approach to basic training.

Gone are the long endurance runs, which officials say can lead to injuries in new recruits who aren’t accustomed to the mileage.

Instead, soldiers will be coached by trainers to do a whole range of exercises that build core strength, flexibility and endurance. Training will be tailored to a soldier’s level of fitness.

A new cafeteria Fort Leonard Wood was also unveiled today. As soldiers walk down the cafeteria line, they see foods marked with red, yellow or green labels.

Green marks high-performance foods, and posters nudge the soldiers to “Go For Green” frequently.

In addition, the cooks have turned off fryers and started baking more entrees. They’re also adding lots of ‘nutrient-dense’ menu options made from fresh food.

To help reinforce these messages, drill sergeants will give one-hour courses in “performance nutrition.” Maybe Shots can invite them over for dinner with our kids?

Why the change in approach? Well, army recruits mirror the general population, which is trending toward the ‘heavier’ side—to put it politely.

More than 9 million Americans of prime recruiting age are too heavy to join up, according to Mission: Readiness, a group of retired senior military officials pushing for better fitness for young people.

Enlisted men and women are no exception. A 2008 Department of Defense survey found that 38 percent of people enrolled in the military health system were overweight or obese.

The new training plan incorporates physical therapists and sports trainers at the unit level to promote proper techniques and injury prevention

If you’d like to see how the Army is putting its soldier-as-athlete model into action, you can download a free iPhone app called “Army Physical Readiness Training.” It was developed by programmers at the U.S. Army Center of Excellence at Fort Gordon, Ga.

The Army plans to make the changes at its other training installations in Fort Sill, Okla.; Fort Benning, Ga.; Fort Jackson, S.C.; and Fort Knox, Ky. in the coming months

Low-Fat Beats Low-Carb For Heart Health

For people at risk for hypertension, reducing fat intake may be key to protecting the heart. According to a study published in the American Heart Association’s journal Hypertension, a low-fat diet is more effective than a low-carbohydrate diet in reducing the risk of developing hypertension, a precursor to cardiovascular problems such as atherosclerosis.

When the two types of diets were compared in apparently healthy participants, the low-fat diet was the winner at improving blood pressure markers, such as blood flow in the arteries. This led the researchers to conclude that low-fat diets “may confer greater cardiovascular protection” than low-carb diets.

Tall, obese men at higher risk for blood clots

Tall and obese men appear more likely to develop venous thromboemoblism, which can lead to a potentially lethal blood clot in the lungs, according to a study published Thursday.

Researchers from the University of Tromso in Norway analyzed height and weight data from 26,714 people and assessed the incidence of venous thromboembolism over 12-1/2 years. In that time, 461 people developed the condition, in which a blood clot (or thrombosis) forms in a deep vein, usually in the thigh, and can move into an artery in the lung. Here’s a basic explanation of the condition fromPatient Health International and a detailed look, including risk factors, from Cleveland Clinic.

In the lung, the clot (called a pulmonary embolism) blocks blood supply and can lead to death. The American Heart Assn. offers this look at venous thromboembolism incidence and fatality statistics.

It begins: “Venous thromboembolism occurs for the first time in about 100 per 100,000 persons each year in the United States. About one third of patients with symptomatic VTE manifest pulmonary embolism, whereas two thirds manifest deep-vein thrombosis alone.”

The new research suggests that being either obese or tall, or the combination, puts men at greater risk for the condition compared to short (5 feet 7.7 inches or shorter), normal-weight men. Men who were obese and taller than 5 feet 11.7 inches were at fivefold greater risk of a blood clot, and men who were tall but of normal weight had a 2.6 times greater risk. Short, obese men had a 2.1 greater risk than short normal-weight men for a blood clot.

Yes, women too: Obese women, short or tall, had a slightly greater risk of a blood clot, scientists reported in Arteriosclerosis, Thrombosis, and Vascular Biology. Tall normal-weight women didn’t have increased risk.

Obesity is already a well-known risk factor for deep-vein thrombosis, but researchers aren’t sure why tall people would be more prone to such clots. The lead author of the study, Sigrid Braekkan, offers an explanation in a press release:

“In tall people the blood must be pumped a longer distance by the calf-muscle pump, which may cause reduced flow in the legs and thereby raise the risk of clotting,” Braekkan said.

There’s nothing a man can do about his height, so researchers say big men – and short ones, of course — should try to stay slim.

In the meantime, here are a few tips for preventing blood clots from the Agency of Healthcare Research and Quality:

— Don’t remain sedentary for more than an hour.

— On plane trips, get up from your seat and move around.

— Try not to cross your legs

— Wear loose-fitting clothing

— Reduce salt in your diet

And here are some tips from the same agency on preventing venous thromboembolsim in the hospital. There, it’s the most common cause of preventable death.

The one-two punch of high-intensity exercise and healthful eating was helpful in getting overweight and obese people to slim down, a study finds.

The study, presented this week at the National Obesity Summit in Montreal, Canada, focused on data on 62 overweight and obese men and women involved in a nine-month program at the Montreal Heart Institute. The participants engaged in two to three weekly one-hour supervised exercise sessions and were instructed on how to follow a Mediterranean diet.

The exercise sessions concentrated on high-interval training, or alternating between short periods of vigorous workouts and rest periods. Interval training has been shown in some studies to promote weight loss as it boosts cardiovascular health. Participants had a five-minute warm-up followed by repeated bouts of exercise at 80% of peak effort. Those were interspersed with brief recovery periods, and the workout finished with a five-minute cool-down. In addition, the study subjects did a 20-minute weight training circuit and were encouraged to do one or two moderate 45-minute exercise sessions a week.

At the end of the study, the men and women on average lost 5.5% of their body mass, reduced waist circumference by 5.15% and increased cardiovascular capacity by 15%. They also had an average 7% decrease in LDL (bad) cholesterol and an 8% increase in HDL (good) cholesterol.

In the study the authors concluded that the supervised twice-weekly interval training program “appeared feasible, safe and time-efficient in this obese population.”

Does Dieting Make You Angry And Stressed?

The idea of reaching for a stick of celery when all you really want is a big slice of chocolate cake, would probably make most people a little grumpy.

And, according to results published in the Journal of Consumer Research, exerting self-control while dieting can in fact make people feel angry and irritable.

The researchers set up four experiments to compare the attitudes of volunteers who were on a diet, with those who ate what they wanted. They found that:

  • Participants who choose an apple over a bar of chocolate were more likely to choose movies which had angry, revenge-filled plots.
  • Those who choose a gift certificate for groceries rather than one for a spa service, showed more interest in looking at angry faces as opposed to more fearful ones.
  • And, in an other experiment, people who chose a healthy snack instead of a less healthy one were more irritated by a public service advert promoting exercise.

Interestingly, the researchers have linked these feelings of irritation, stress, and anger to the act of exerting self-control while dieting, rather than the “dieting” itself.

The researchers point out that public policy makers should be more aware of the potential negative emotions, which can result when the public are encouraged to exert more self control over their daily choices.

What about you — does being on a diet make you feel more irritated or angry? How do you make healthy food choices without feeling like you’re denying yourself?
