Pearls of Wisdom

A dairy farmer who believes a happy cow is a productive cow has discovered an unusual way to relax his herd and increase milk yields – tai chi. Rob Taverner performs the ancient martial art in front of his 100 cows every morning to get them in the right moo-d to produce lots of milk.

The 44-year-old organic farmer visits the animals at 9am each day to run through his ten-minute routine of slow movements and breathing techniques – dressed in his distinctive overalls and wellies.

He said: ‘Tai chi is all about leaving your problems behind and getting into a better zone and my mood definitely transfers to the cows.

‘Like all animals, they are very receptive to human emotions and can sense feelings such as relaxation, calmness and happiness.

‘Some people think what I do is ridiculous but I have some very content cows and I would do anything to keep them that way. As any good dairy farmer will tell you, a happy cow is a productive cow.’

This isn’t to say that you can’t be an individual within in marriage. Individuality is a part of life. But carelessness is not. Or at least there should be no room for it when it comes to your health. We oftentimes damage our bodies with bad behaviors because we can. No one feels the consequences except for us—or so we think. That’s what hit me about marriage: My pain is now shared by someone else. The sad thing is, it shouldn’t have taken me so long to figure it out.

Aerobic exercise can increase brain size, keeping you mentally sharp

Another reason to follow through with that New Year’s resolution: Aerobic exercise keeps the aging brain — as well as the aging body — in fighting form. Researchers at the University of Pittsburgh, the University of Illinois, Rice University and Ohio State showed that a program of aerobic exercise, over the course of a year, can increase the size of the hippocampus — a part of the brain key to memory and spatial navigation — in adults ages 55 to 80.

The hippocampus is known to shrink in late adulthood, leading to memory impairment.

The results were made public Monday by the journal Proceedings of the National Academy of Sciences. They back up earlier research that has shown a correlation between fitness level and brain function.

To complete the study, the team recruited 120 older people who didn’t exercise regularly.  Half were randomly assigned to an aerobic exercise program, walking around a track three days a week for 40 minutes per session.  The other half embarked on a stretching-and-weights program.  Both groups were carefully coached and monitored.  They provided blood samples, performed spatial memory exercises and were given MRIs at the beginning, halfway point and end of the research period.

The group doing aerobic exercise had increases in hippocampus volume: up 2.12 % in the left hippocampus, and 1.97% in the right hippocampus.  The stretching group, on the other hand, had decreased hippocampus volume:  down 1.40% on the left and 1.43% on the right.

The participants also performed spatial memory exercises.  Again, the aerobic exercise group had better function by the end of the year of exercise.  Blood tests also showed an increase in the levels of brain-derived neurotrophic factor, a chemical involved with learning and memory, among the walkers.  Increases in hippocampal size were associated with increased amounts of brain-derived neurotrophic factor.

“We demonstrate that loss of hippocampal volume in late adulthood is not inevitable and can be reversed with moderate-intensity exercise,” the team wrote, suggesting that a few laps around the track might be a particularly cost-effective way to treat a widespread health problem — without the side effects of medication.

And, researchers said, it’s never too late.  “Starting an exercise regimen later in life is not futile for either enhancing cognition or augmenting brain volume,” the team wrote.

The graceful, dancelike progression of meditative poses called tai chi originated in ancient China as a martial art, but the exercise is best known in modern times as a route to reduced stress and enhanced health. After reviewing existing scientific evidence for its potential health benefits, I’ve concluded that the proper question to ask yourself may not be why you should practice tai chi, but why not.

Tai Chi is a low-impact activity suitable for people of all ages and most states of health, even those who “hate” exercise or have long been sedentary. It is a gentle, calming exercise — some call it meditation in motion — that involves deep breathing but no sweat or breathlessness.

It places minimal stress on joints and muscles and thus is far less likely than other forms of exercise to cause muscle soreness or injury. It requires no special equipment or clothing and can be practiced almost anywhere at any time, alone or with others.

Once the proper technique is learned from a qualified instructor, continuing to practice it need not cost another cent.

The many small studies of tai chi have found health benefits ranging from better balance and prevention of falls to reduced blood pressure, relief of pain and improved immunity.

The latest and perhaps best designed study was conducted among patients with debilitating fibromyalgia, a complex and poorly understood pain syndrome.

Dr. Chenchen Wang and colleagues at Tufts Medical Center in Boston reported in August in The New England Journal of Medicine that tai chi reduced pain and fatigue and improved the patients’ ability to move, function physically and sleep. The benefits persisted long after the 12 weeks of tai chi sessions ended.

The study was financed primarily by the National Center for Complementary and Alternative Medicine, a division of the National Institutes of Health. To be sure, documenting tai chi’s purported health benefits is a challenge. As an editorial in the journal noted, it is virtually impossible to design an ideal study of tai chi. There is no “fake” version that could serve as a proper control to be tested against the real thing. Thus, researchers have to rely on less-than-perfect comparison groups. In the fibromyalgia study, for example, the control group was given stretching exercises and wellness education.

And unlike evaluations of drugs, tai chi studies cannot be double-blinded such that neither patients nor researchers know which group is receiving which treatment. Those guided by a tai chi master would undoubtedly know who they are and could be influenced by the teacher’s enthusiasm for the practice.

Still, scientists have come to better understand and appreciate the mind-body connection, which for too long was dismissed as nothing more than a placebo effect, and most doctors are now more willing to accept the possibility that stress-reducing activities can have a profound effect on health.

A Stress Reducer

There is no question that tai chi can reduce stress. As the study authors described it, tai chi “combines meditation with slow, gentle, graceful movements, as well as deep breathing and relaxation to move vital energy (called qi by the Chinese) throughout the body.”

If nothing else, this kind of relaxing activity can lower blood pressure and heart rate, improve cardiovascular fitness and enhance mood. For example, a review in 2008 found that tai chi lowered blood pressure in 22 of 26 published studies.

Thus, it can be a useful aid in treating heart disease, high blood pressure and depression, conditions common among older people who may be unable to benefit from more physically demanding exercise.

Regular practitioners of tai chi report that they sleep better, feel healthier and experience less pain and stiffness, though it cannot be said for certain that tai chi alone is responsible for such benefits.

Yet as Dr. Wang and co-authors noted in an earlier report that analyzed the literature on tai chi and health, a majority of studies have been small and poorly controlled, if they were controlled at all. Therefore, the tai chi practitioners could have been healthier to begin with or could have practiced other health-enhancing habits.

Perhaps the best-documented benefit of tai chi, and one that is easiest to appreciate, is its ability to improve balance and reduce the risk of falls, even in people in their 80s and 90s. The moves are done in a smooth, continuous fashion, as weight is shifted from one leg to the other and arms are moved rhythmically. This can improve muscle strength and flexibility, and enable the muscles in the legs and hips to function in a more coordinated and balanced manner. Thus, practitioners become more stable and sure-footed.

Another benefit, again especially important to older adults, is the apparent ability of tai chi to improve immune function. In a 2007 study also financed by the Complementary and Alternative Medicine center, those who practiced tai chi had a better response to the varicella zoster vaccine that can help prevent shingles.

Talk to a Doctor First

Tai chi is not a substitute for professional medical care, but rather an adjunct to such care and a way to keep debility at bay. As with other forms of alternative medicine, it is best to consult your physician before signing up for instruction.

This is especially important if you are a pregnant woman or have serious physical limitations, joint problems, back pain or advanced osteoporosis. While such conditions do not preclude practicing tai chi, you may have to modify or avoid certain positions.

Although tai chi is a gentle exercise, one can get carried away. Overdoing any activity, including tai chi, can result in sore or sprained muscles. On its Web site, the Complementary and Alternative Medicine center notes that “tai chi instructors often recommend that you do not practice tai chi right after a meal, or when you are very tired, or if you have an active infection.”

Also important is assurance that your instructor is well qualified. Instructors do not have to be licensed, and the practice is not regulated by any governmental authority. There are many styles of tai chi — the yang style is most commonly practiced in Western countries — and there are no established training standards.

Traditionally, would-be instructors learn from a master teacher. Before choosing an instructor, you’d be wise to inquire about the person’s training and experience.

Learning tai chi from a qualified instructor is critical. The Complementary and Alternative Medicine center cautions that trying to learn it from a book or video is no guarantee that you will be able to perform the moves safely and correctly. Reliable sources of instructors include Y.M.C.A.’s and Y.W.C.A.’s, and well-run commercial gyms.

Finally, attending a few sessions or even a 12-week course in Tai Chi is not enough to guarantee lasting health benefits. As with any other form of exercise, tai chi must be practiced regularly and indefinitely to maintain its value.

As a fitness tool, tai chi packs a wallop

The sight of someone standing alone on a beach or a patch of grass performing what looks like slow-motion kung fu has become a familiar one in recent years as the health-conscious public has come to discover an ancient Chinese secret. All over San Diego County, the martial arts have gone mainstream, thanks to the widely popular tai chi chuan.

“Tai chi is (one of) the oldest forms of martial arts, dating back 1,500 years,” says Ben Stanley, Sifu – or lead instructor – at White Dragon Martial Arts Schools, “but its benefits have withstood the test of time.”

Rich Nye (center) led a tai chi chuan class at the White Dragon Martial Arts School in Clairemont. Tai chi, one of the oldest forms of martial arts, dates back 1,500 years.

Practiced in a slow, controlled manner, tai chi may appear more relaxing than invigorating, but its appearance easily can be deceiving.

“An hour of tai chi three to four days per week is a great amount of exercise,” Stanley adds. “It is a good, mild form of cardio that puts your heart rate in the best range to burn fat and lose weight.”

It may seem mild, but when it comes down to it, tai chi is a martial art that can still pack a powerful punch.

“Tai chi is slow and relaxed, but for self-defense, it is sped up,” Stanley says. “Each of the movements has real-world applications in combat, based on the principle that ‘one technique beats many.’ You never fight force against force, but you use principles to maximize your power. That’s tai chi in a nutshell.”

EXERCISE YOUR OPTIONS  JUNE 6, 2006

– CHRISTINA ORLOVSKY

WHAT TO EXPECT: Students of varying ages, from young children to senior citizens, and a range of skill levels. White Dragon ranks tai chi students in a belt system similar to kung fu or karate, and tailors classes and private lessons to rank and experience level. Private lessons include instruction on formalities, stances, rules and history, while group classes give students the opportunity to practice “push hands,” or the tai chi form of sparring. Students also can expect an atmosphere of respect: Students and instructors bow to one another in salutation.

WHAT IT BENEFITS: The list of body and mind benefits is almost endless for this ancient sport. Sifu Stanley explains that tai chi is a way of improving health and longevity, as well as practicing self-defense, because, as he relays, “It’s bad for your health to let someone punch you in the nose!” Tai chi has been found to relieve stress and stress-related illness, reduce blood pressure and stimulate the immune system. It can also improve circulation, flexibility and mobility, making it popular with the baby boomer set. It has even been suggested that the athletic art’s complex patterns can stimulate mind function for elderly adults experiencing dementia.

WHAT IT COSTS: White Dragon invites first-timers to take a free one-on-one introductory lesson by registering through the Web site. Class packages vary, but include private lessons as well as unlimited group classes six days a week. Outdoor classes are also offered, and tournaments are held throughout the year.

THE BIOMECHANICS OF THE MEASURED, FLOWING MOVEMENTS OF TAI CHI DEMONSTRATE THAT SLOWER SPEEDS LEAD TO GREATER MUSCLE ACTIVATION IN THE LOWER BODY.

by Yun Shi | August 27, 2009

If you’re familiar with exercise, you know that speed is an important factor to control. For common exercises like running and weight lifting, volumes of research has shown that it’s generally necessary to move faster for a more intense cardio workout and to make measured, controlled movements for building muscles. Other workouts, like mind-body exercises (e.g., yoga and tai chi), are somewhat harder to pin down. They aren’t cardio exercises, nor are they strictly muscle building.

The slow, flowing movements of mind-body exercises have been around for centuries, and they have been shown to help people develop balance, flexibility, and muscle function. Consequently, they’ve been increasing in popularity, both for physical therapy and personal enjoyment. While these exercises are widely practiced around the world, the biomechanical basis for their effects is not well known. To gain further insight, Ge Wu and Xiaolin Ren, biomedical engineers from the University of Vermont, chose to study how the unhurried steps of tai chi benefit its practitioners.

Experienced tai chi instructors like Ben Stanley and Leslie Edwards often remind their students that slower is better. Stanley says that “it’s about breathing and being attuned to the muscles as you’re moving. It’s important not to rush it, or you could miss the full benefits of the exercise.” In fact, Edwards pointed out that “the slower you go, the harder it is, and you definitely feel it in your legs.”

Tai chi can certainly be a test of patience for the inexperienced, as it is normally performed about 10 times slower than an average walk (2 mph), but it has a similar intensity to a moderate aerobic workout. Much of its direct benefits have been reported in the legs. To determine if and how the deliberate, gradual transitions in tai chi were responsible for these benefits, Wu and Ren employed a combination of biomechanical force plates, a camera-based motion analysis system, and EMG (electromyography) electrodes.

The 12 subjects, grouped as young (22-34 years) and old (64-80 years), performed a fundamental tai chi movement, “part wild horse’s mane,” at various speeds. Besides marking the participant’s motion from shoulder to toe, Wu and Ren measured the duration and magnitude of activation for six muscles that are key to ankle, knee, and hip mobility.

They found, as expected, that the duration of muscle activation was longer during slower motions in all six muscles. The effect was most significant for the rectus femoris (one of the quadriceps muscles) and semitendinosus (one of the hamstrings). When the participants sped up, these muscles lost this activation duration, while two muscles, the soleus (part of the calf) and semitendinosus, showed an increased activation. Thus, speeding up created an overall loss in muscle activation.

Age was also a factor in muscle activation. At slower speeds, younger subjects showed more muscle activation than older participants. This could be the result of older practitioners having a more limited range of movement. Stanley has often observed that it’s “difficult for older people to really sink down and fully extend in some of the postures compared to younger students,” but he has “seen posture, balance, and overall well being improve through time.”

Overall, Wu and Ren observed that speed had a greater impact on lower body muscles than other factors, like age or depth of movement. Their work demonstrate that slow, controlled movements can activate muscles more than rapid motion. The approach can also be used to study additional movements in tai chi and other exercises like yoga—a thorough understanding of exercise biomechanics should allow people to make more informed choices about what activities to pursue.
