The researchers at Osaka International University and Kobe University studied the differences between the sweating responses of men and women as they participated in exercises in which the intensities were changed, i.e., four groups of trained and untrained females and males cycled continuously for an hour in a controlled climate with increasing intensity intervals. The results? Men were shown to be more efficient at sweating, and that while exercise training improves sweating in both sexes, the degree of improvement is greater in men. Untrained females had the worst sweating response of all requiring a higher body temperature to begin sweating. The bottom line? According to the study’s coordinator, Yoshimitsu Inoue, “It appears that women are at a disadvantage when they need to sweat a lot during exercise, especially in hot conditions.” This finding may explain why men and women cope differently with extremes in temperatures, with women adapting better to hot environments, but men having greater efficiency of action under the same conditions.

But, sweat or “glow,” exercise for both sexes is essential for good health, including a strong musculoskeletal system.

New research at Mid Sweden University and the Karolinska Institue found that the maximum capacity for oxygen uptake is twice as great among active senior men compared with men who do not exercise. (Twice as much oxygen intake!) “The high values for maximum oxygen-uptake capacity that we have measured have never been reported before in a population of men of advanced age,” says Per Tesch, professor of sports science who led the study of seniors who are still active skiers. (Some of Sweden’s skiing icons, some now more than 90 years old, took part!)

The conclusion of this study is that “humans have a great potential to maintain a high level of physical work capacity and, thereby, a better quality of life even at advanced ages.” The study is part of a larger collaborative project whose ultimate purpose is to study how musculature, the circulatory apparatus, and performance are affected by lifelong exercising well into senior years.

So, there you have it… One more good reason to get your body moving and to keep going no matter what your age!

Obesity is an enormous problem of epidemic proportions in this country. Factors such as changing eating habits (from healthy to “fast, fatty, and excessive”) and a sedentary lifestyle (for children as well as adults) have contributed to the obesity problem. It is also postulated that excessive consumption of fat creates failures in the signal transmitted by neurons controlling satiety in a region of the brain called the hypothalamus, and that these failures can lead to uncontrollable food intake and, consequently, obesity.

The researchers demonstrated that exercising (in this case exercising obese rodents) showed signals of restored satiety in hypothalamic neurons and decreased food intake. These findings confirmed that physical activity contributes to the prevention and treatment of obesity, not only by increasing energy expenditure, but also by modulating the signals of satiety and reducing food intake.

So, there you go, another good reason to exercise brought to you by your friendly chiropractor in San Jose!

Let’s face it, life these days has become a spectator sport for many people. Kids sit in front of the television or their computers — and so do adults! Business often demands it and, after a long day of sitting at the computer at the office, “relaxation” or “family time” frequently comes in the form of vegging in front of the TV. There is growing evidence to suggest that people (and in the case of this particularly study, women) who are physically active in mid-life and beyond have a lower chance of dementia, as well as the “more minor” forms of cognitive impairment in old age. However, until now there has been less clarity regarding the importance of physical activity for women early in life and at different stages of life. The researchers at Sunnybrook health Sciences Centre in Canada compared the physical activity and cognition of 9,344 women at different ages (teenage, age 30, age 50, and late-life) to investigate the effectiveness of activity at different life stages on later cognitive abilities.

“Our study shows that women who are regularly physically active at any age have lower risk of cognitive impairment than those who are inactive, but also that being physically active at teenage is most important in preventing cognitive impairment,” said Laura Middleton, PhD, who lead the research. And, in addition, she and her research team found that women who were physically inactive as teenagers, but became physically active at age 30 or age 50 had significantly reduced their odds of cognitive impairment as well compared to those who remained physically inactive. “Low physical activity levels in today’s youth may mean increased dementia rates in the future,” Middleton added.

What’s good for the body is always good for the brain. So be smart and stay that way by being physically active. “Motion is Life,” so get moving!

Kirsty Wigglesworth / AP If you’ve been reading my blogs, you know that as your San Jose chiropractor I believe that exercise, at any age, is one of the main keys to good health and longevity. You’ve heard me say that “motion is life,” and it becomes all the more critical as people age. Movement slows down degenerative changes and often prevents many of them from occurring at all. In addition, movement enhances blood flow, respiration, and elimination, and keeps every organ stronger and healthier. So, you can imagine my excitement when I read about a “senior’s playground” that opened in London’s Hyde Park recently. The playground was the result of senior residents campaigning for more facilities to help older people to get fit. Brilliant! Talk about an idea whose time has come! Organizers said that a large group of older people began lining up early in the morning to try the six low-impact fitness machines that included a cross-trainer, a stationary bicycle, and a sit-up bench. The playground is aimed at people over 60, but the gentle exercise would also be beneficial for patients recovering from operations or injury. Similar play areas for the elderly are already availabe in other European countries. So, why not here in the U.S.? Older people need a “free” friendly outside exercise area where they not only won’t feel intimidated by younger people, but will be able to socialize as they improve their health. So, got a pen and paper handy? How about a laptop? Even your cell phone will work! Start a campaign in your area for a “playground for seniors.” If you don’t personally need one today…you will sometime in the future!

As a chiropractor, I treat plenty of teenagers (as well as adults) who’ve sustained sports injuries. When it comes to the “weekend warrior” syndrome, it seems that teenagers don’t realize, anymore than their parents and other adults who indulge in sport activities do, just how important getting in shape prior to getting fully involved can be. So I was happy to read the following article and recommendations for high school pitchers and I want to pass it along to you.

High School Pitchers Need To Train Properly Before Season To Avoid Serious Injuries

 High school pitchers who go full-speed the first day or week of spring training may be headed down the road to serious injury.

“A large number of high school athletes take the winter off and just go out and start throwing as hard as they can,” said Matt Holland, a physical therapist with The Methodist Center for Sports Medicine in Houston. “The problem is that their arms are not in baseball shape and they open themselves up to serious shoulder and elbow injuries.”

The rotator cuff is a group of muscles that act to stabilize the shoulder especially during the throwing motion. An inflamed rotator cuff (tendonitis) can cause pain when lifting your arm and will most likely dramatically affect a player’s performance on the field. Problems with the rotator cuff can not only damage the rest of the shoulder, but may also lead to elbow and other arm problems that shorten the careers of many pitchers.

Why is this so? When a person avoids exercise, joints become even less mobile and the surrounding muscles shrink, causing increased fatigue and pain. Read more…

The study, “Exercise training in Parkinson’s disease: Neural and functional benefits”, in partnership with Arizona State University is funded by the National Institutes of health and begins as Ali, who has suffered from Parkinson’s disease for more than 20 years, helped unveil the new Parkinson’s center at the Barrow Neurological Institute at St. Joseph’s Hospital and Medical Center in Phoenix. The 10,000 square-foot center is the most comprehensive of its kind in the nation and double the size of the original center that first opened in 1997.

From its beginning, Ali and his wife, Lonnie, have wanted the focus of the center to be helping Parkinson’s patients stay active and involved. This research study underscores that focus and passion. In conjunction with Arizona State University, researchers will test the participants who are aged 50-70. During the trial participants will follow a structured exercise program called “pole-striding”, which is walking with ski-like poles.

“Until now we have had only anecdotal evidence that regular physical activity is disease modifying,” says Darolyn O’Donnell, who will help lead the study at the center. O’Donnell explained that participants will undergo 12-weeks of pole-striding for three days a week as they walk for about 45 minutes during each training session. “One of the key elements of this study is that we are using a simple exercise that can be duplicated by anyone.”  Read more…

Little else feels better than a good foot massage or stretch.

The American Podiatric Medical Association offers these suggestions for keeping your feet happy and healthy:

• Stretch your arch, either by placing a towel around the ball of your foot and gently pulling with your hands, or by standing in front of a wall and slightly leaning forward until you feel your arches stretch.
• Strengthen toes by placing a toe separator between them and squeezing toes together for five seconds; do it 10 times. Or, wrap toes with a rubber band and spread against the resistance.
• Grab a golf ball or other similar-sized ball, and place it on the floor under your bare feet. Gently roll it around under your feet.
• Stand up on the balls of your feet and hold for five seconds; do this 10 times.
• Stand with feet flat, then one at a time lift your heel from the floor and roll weight into the ball of your with your toes pointing down. Flex your foot, hold, and repeat on each foot.

(healthDay News) — If you want to lose weight, exercise and diet are crucial. But a new study says other factors appear to play a role, too — including the number of TVs in your house and the presence of exercise equipment.

“The home environment really came out as a stronger factor than we would have anticipated,” Suzanne Phelan, assistant professor of kinesiology at California Polytechnic State University and lead author of the new study, said in a news release.

Phelan and colleagues looked at the results of surveys of 167 people who lost a big chunk of their body weight — at least 10 percent — and managed to keep the pounds at bay for five or more years. The researchers compared this group to two other groups of people who were overweight or obese.

The researchers investigated what set the weight-losers apart from the others, and published their findings in the October issue of the Annals of Behavioral Medicine. Read more…
