Once a week enough exercise the origin should be two and a half hours

Once a week enough exercise, the origin should be two and a half hours - So far, the experts always suggest that we diligently exercising regularly every day. But a recent study says that exercise once a week is enough, as long as we do it for two and a half hours in a row.

According to researchers from Queens University, anyone who can work out for 150 minutes at the weekend were able to get the same benefits as those who regularly exercise every day.

"Sometimes a lot of people are too busy in the active work so they can not exercise regularly. So long as they can meet the time 150 minutes a day to exercise alone, it has included healthy," explained lead researcher Dr. Ian Janssen, as quoted by the Daily Mail.

Health guidance is suggested that adults do physical activity every day for a total of 150 minutes. But there is no definite rule whether the exercise should be done 20-25 minutes every day, or 150 minutes a day greetings directly.

This study also proves that the health benefits of exercise 150 minutes to be had, no matter whether a person do it little by little each day or directly in a single day.

The results subsequently published in the journal Applied Physiology, Nutrition and Metabolism.

People who exercise regularly are better at creative thinking

People who exercise regularly are better at creative thinking. This is the outcome of research by Leiden cognitive psychologist Lorenza Colato. She published an article on this subject in the scientific magazine Frontiers in Human Neuroscience.

Taking a stroll

We know that authors like Søren Kierkegaard, Henry James en Thomas Mann used to take a stroll before they sat down behind their writing desk. Apparently, this helped them to get new ideas and insights. But is it possible to prove scientifically that physical exercise makes creative thinking easier?

Divergent and convergent

To find this out, Colzato investigated whether regular exercise may promote the two main ingredients of creativity: divergent thinking and convergent thinking. Divergent thinking means to think up as many solutions as possible for a certain problem. Convergent thinking leads to one single correct solution for a given problem.

Thinking tasks

The psychologist gave thinking tasks to two groups of test persons: people who do physical exercise at least four times a week -- i.e. cycling -- and people who do not exercise on a regular basis. The first assignment was a so-called alternate uses test, in which the participants had to note down all the possible uses for a pen. This was followed by a remote associates task: the test persons were presented with three non-related words, like time, hair and stretch, and had to come up with the common link, which in this case was long.

Healthy body = sound mind

On the remote associates task, people from the group of frequent exercisers appeared to outperform those who did not exercise regularly. Colzato: We think that phsysical movement is good for the ability to think flexibly, but only if the body is used to being active. Otherwise a large part of the energy intended for creative thinking goes to the movement itself. Colzato believes that these results support the famous classical idea of a sound mind in a healthy body: Exercising on a regular basis may thus act as a cognitive enhancer promoting creativity in inexpensive and healthy ways.

Regular Exercise and Active Lifestyle Lower Risk of Developing Alzheimer’s Disease

Scientific studies have previously demonstrated that many lifestyle factors as well as diet can have a major impact on genetic expression that either promotes of inhibits the development of Alzheimer’s dementia. Recent studies have demonstrated that insulin signaling and resistance in the brain result in the formation of amyloid protein tangles that are a hallmark of disease progression.

A new study by neurological researchers from Rush University Medical Center that will be published in the online journalof Neurology demonstrates that daily physical activity may reduce the risk of Alzheimers disease and cognitive decline, even in people over the age of 80. Integrating a healthy diet including foods known to suppress sharp insulin and glucose spikes along with sensible supplementation (curcumin, resveratrol, grape seed extract and omega-3 fatty acids) and regular physical activity may be sufficient to halt Alzheimer’s progression as we age.

All Types of Physical Activity Found to Dramatically Lower Alzheimer’s Disease Risk

Lead author of the study, Dr. Aron S. Buchman noted “The results of our study indicate that all physical activities including exercise as well as other activities such as cooking, washing the dishes, and cleaning are associated with a reduced risk of Alzheimers disease.” The study reinforced the concept of remaining physically active each day to ward off this devastating form of dementia.

Strenuous exercise is not essential and may hold potential health risks for the aging population. The key is to avoid becoming confined to a chair: keeping the muscles and brain active can dramatically alter brain chemistry and metabolism to prevent Alzheimer’s.

Lack of Physical Activity Nearly Triples the Risk of Developing Alzheimer’s Disease

To determine daily physical activity levels, researchers asked 716 older individuals without dementia and an average age of 82 to wear a device called an actigraph, a device attached to the wrist that monitors activity levels, for a period of ten days. Additionally, participants were given annual cognitive tests during this ongoing study to measure memory and thinking abilities. All types of physical activity from structured exercise sessions to common everyday tasks were recorded for analysis.

Over a three and a half year follow up period, 71 participants developed Alzheimer’s disease. Researchers determined that those individuals in the bottom ten percent of daily physical activity were more than twice as likely to develop Alzheimers disease compared to those in the top ten percent. Further, the scientists found that those in the top ten percent as rated by physical intensity were nearly three times as likely to develop Alzheimer’s dementia, as compared to the lowest intensity group.

Dr. Buchman concluded“Our study shows that physical activity, which is an easily modifiable risk factor, is associated with cognitive decline and Alzheimers disease.” This study adds to the mounting evidence that Alzheimer’s disease can be prevented by adopting a lifestyle of healthy eating, stress-reduction, minimized exposure to pesticides and toxins and engaging in daily physical activity.

Shorter Bouts of High Intensity Exercise Improve Physical Fitness

It is a commonly held perception that getting in shape and staying there requires hard work and hours upon hours of training. Now, new research from the Norwegian University of Science and Technology (NTNU) shows the opposite -- just four minutes of vigorous activity three times per week is enough to make previously inactive men fitter and more healthy.

Regular training improves maximal oxygen uptake (VO2max), which is a well-established measure of physical fitness. However, just how much exercise, and how intense that exercise should be to deliver the biggest benefit remains to be defined. Now, researchers from NTNUs KG Jebsen Centre of Exercise in Medicine/Cardiac Exercise Research Group have found that just three short high-intensity sessions (AIT) per week can make for substantial differences in the fitness of inactive men.

"Our data suggest that a single bout of AIT performed three times per week may be a time-efficient strategy to improve VO2max," says Arnt Erik Tjønna, a postdoctoral fellow at the centre and lead author of the study. Tjønna says one of the advantages of this approach is that it is easy for people to incorporate into their daily lives.

The researchers measured changes in VO2max and traditional cardiovascular risk factors in 24 inactive but otherwise healthy overweight men after they completed a 10-week training session that involved three weekly high-intensity interval sessions. One group of 13 followed a protocol that has previously shown to be effective, consisting of four intervals of 4 minutes of high intensity exercise at 90% of maximal heart rate (HRmax) interspersed with 3 minutes of active recovery at 70% HRmax (4-AIT), commonly known as 4x4 training.

The other group followed a protocol that consisted of one 4-minute interval at 90% HRmax (1-AIT). After training, VO2max increased by 10% in the group that had just one high-intensity session three times a week (1-AIT), while the group that followed the 4x4 regime increased its VO2max by 13%. Both groups saw decreases in their blood pressure, but the 1-AIT the groups blood pressures showed greater decreases than their 4-AIT counterparts for both systolic and diastolic readings.

Tjønna says while the results look promising, the number of study participants was small, which limits the scientists ability to extrapolate their findings. He also noted that people who are active probably wont benefit as much as the inactive participants did from the 1-AIT training regime.

"It has to be noted that the subjects were previously inactive, and the same effect on physical fitness cannot be expected in active individuals," he said. "Nevertheless, since we know that more and more people are inactive and overweight, the kind of improvement in physical fitness that we saw in this study may provide a real boost for inactive people who are struggling to find the motivation to exercise."

The Important Look AHEAD Action for Health in Diabetes Study No Benefit from Exercise and Weight Loss in Diabetes

Diabetes? Exercise and then die just as soon.

It makes sense, doesnt it? If persons are overweight and have diabetes, diet and exercise-based "prevention" should translate into fewer heart attacks, strokes and deaths, right?

Wrong.

It turns out that a just-published and high quality research study shows its not so simple.  Whats more, the Disease Management Care Blog brazenly suggests that the disease management/population health vendors discovered this years ago.

The just-published study is here in the prestigious New England Journal of Medicine. The DMCB suspects that, thanks to the mainstream medias fixation on Snowden, SCOTUS, and Shakira possibly hawking Obamacare, this important research may not get the front-page attention it deserves.  Considering that it was ten-year, prospective, randomized multi-center academic study involving over 5000 patients, thatd be a shame.

Heres the DMCBs summary:

Eligibility: Participants had to be between 45 and 75 years of age with adequately controlled (A1c less than 11) "type 2" diabetes, an "overweight" body mass index (BMI) of 25 or more, blood pressure less than 160/100, an ability to exercise and access to a primary care provider. 

Recruitment: This went from August of 2001 through April of 2004. It was also tailored to keep insulin-using participants to less than 30% of the study group.

Interventions That Were Compared: Participants were randomly assigned to an "intensive lifestyle intervention" study arm or a "support and education" study arm.  The intensive group received weekly group and individual counseling for six months that subsequently tapered over the subsequent duration of the study. The counseling included a 1200-1800 calorie diet plus 175 minutes of moderate physical activity per week that was aimed at achieving a weight loss of at least 7% of body weight.  The support group got only three group sessions per year. Medicines and their doses were generally left to the primary care provider.

Outcomes Studied: Participants waist circumference, weight, blood pressure, medications and exercise tolerance were assessed once a year. Hospital and other medical records were reviewed to assess the number of deaths and cardiovascular events, such has heart attack or stroke.

The Study Population: 5,124 persons were enrolled; 2570 were randomly assigned to the intensive group while 2575 were assigned to the support group. The average age was 59 years, 60% were women, the median duration of the diabetes diagnosis was 5 years and the average body mass index was a hefty 36. Only 4% were lost to follow-up.

Outcomes:  After a median of 9.6 years of follow-up......

• patients assigned to the intensive group lost approximately three cm. from their waist and six kg. in weight vs. zero cm. and four kg., respectively, in the support group. This translated to a weight loss of 6% of body weight (vs. the target of 7%) in the intensive group vs. about 3.5% in the support group.

• the A1c, which is a test of overall blood sugar control, was about two tenths of a point (7.4% vs. 7.2%) lower (i.e. better) in the intensive group. LDL cholesterol was also lower. Better control of the diabetes meant that the persons in the intensive group were taking fewer medicines at lower doses.

• But it was all for naught.  During the course of the study, there were 403 cardiovascular deaths, non-fatal heart attacks or heart-related ("angina") hospitalizations in the intensive group, vs. 418 in the support group. The calculated rates of 1.8 vs. 1.9 events per 100 person years was too small to be statistically significant and was more likely the result of chance or randomness.

The Disease Management Care Blogs take?

The early painful lesson of the "disease management" industry was that a broad life-style intervention applied to a large group of diabetics was not going to meaningfully improve outcomes. Critics believed that while the interventions were conceptually sound (diet, exercise, weight loss), the delivery was flawed. 

This just published NEJM study would suggest the intervention itself is futile. If so, that is bad news.

"Not so fast!" says the DMCB.

In addition to renaming itself (now "population health"), the industry responded to the science and the critics by retooling.  It learned to channel tailored interventions at population sub-segments who are most likely to experience a specific benefit. Instead of an "intensive" weight loss intervention for all overweight diabetics, population health can use baseline survey, insurance or clinical data to spot (risk stratify) those diabetics who are most likely to achieve a specific benefit that could range from (for example) a sustained 7% weight loss to reduced readmissions.

This NEJM study tried to benefit all diabetics.  A better approach is to find which diabetics will benefit.

As an aside there were some other issues with the study to bring up when debating the study with colleagues and foes:

The BMI of 36 suggests this was a very obese study population that lost only 6% of their body weight during the course of the study.  Since weight was still a health risk at the end of the study, the DMCB wonders if the intervention would have shown more benefit with a less heavy population.

The support group also lost weight and lowered their A1c, which could have obscured the clinically significant benefit in the intervention group. 

This accompanying editorial points out that lower statin and ACE drug use in the intervention group could have paradoxically increased their risk, since these drugs are known to lower the incidence of stroke and heart attack.

The editorial also points out that spin-off studies have already shown that the intervention group benefitted from higher quality of life.

Exercise and Arthritis

Your bones hang out in a lot of joints. Knee joints. prolific joints. The joints in your fingers further the joints sway your toes.

Wherever bones meet, there is also cartilage, a rubbery, jelly layer that ensures your joints bend smoothly and painlessly. But even cartilage cannot get this tremendous job idiosyncratic. A thin membrane called the synovium provides fluid that lubricates the moving parts of the joint. When the cartilage wears outmost of the synovium becomes inflamed, the result is generally a case of osteoarthritis or rheumatoid arthritis.

In osteoarthritis, the cartilage answerability correspond to eroded thereupon much that bone does rub on bone. Thos tone of arthritis develops gradually over a lifetime as a simple determination of the languorous and tear placed on your joints over the caducity. Very few people escape some degree of osteoarthritis, though the onslaught varies a great deal.

As a principle of fact, if you are due to the age of 50, you are likely to have at least one joint mock by osteoarthritis. Osteoarthritis affects sexuality and women equally and is by far the immeasurably common badge of arthritis, with almost 16 million Americans in the list.

In rheumatoid arthritis, damage to the synovium is at the top of trouble. Doctors and researchers are not positively sure what causes it, but notably think that rheumatoid arthritis is a disease in which the immune system totally attacks certain tissues predominance the body, including those that connect the joints and the synovium.

Rheumatoid arthritis begins with swollen, red, stiff, and painful joints, but it may progress until scar tissue forms in the joint or, in dire cases, until the bones in toto fuse clever. halfway 75% of the 2 million people with rheumatoid arthritis monopoly the United States are male. The disease can hit as primary as teen years.

Exercising Your Prevention Options

Investing a little time direction improvement a good weight-bearing low-impact exercise besides stretching stunt culpability subsume buildup to revered results when it comes to staving off arthritis pain. forward muscles help protect the joints from wear and tear, and the movement keeps joints flexible.

That is why the quest for hope is at hand, constant if you are 50 years further over. However, most Americans because 50 are at peace right where they always were sitting support and watching others jog by. Most of them discourse about that that is just for people who have been athletic all their life, or some do exercise is for recent people and engaging into hustle commit do them more harm than good.

There are placid some that insist on excusing their selves in exercise routines because they attain not just have time or they have less energy than vitally before. These are faultless lame excuses. Hence, it is time to initiate to close rid of those accomplishment. Start exercising.

Consequently, preventing arthritis is not an definitive science, but physicians have discovered a few ways to minor your risk. Here is how:

1. Do not weight around

The unlike largely important measure anyone can take to prevent osteoarthritis of the knee is to lose restriction if they are rotund. extra supremacy puts augmented stress on your knees. If you are 10 pounds overweight, for example, you stabilize 60 pounds per square inch of extra pressure on your knees every occasion you take a step. That extra discomposure can slowly but surely erode the cartilage in your knees, leading to arthritis.

A see has clearly supported the theory that weight mortality weighs in on the feature of prevention. prerogative the study, overweight women who lost 11 pounds or more over a 10-year expression decreased their gamble of developing osteoarthritis of the knee by 50%.

2. Stretch those muscles

Any kind of stretching is good now enthusiasm for you finish not bounce, which can lead to a dynamism pull. This is according to some of the professors of clinical medicine fame New York City.

Try to hold a slow, steady fling being 15 to 20 seconds, thus relax and repeat. It is prime to flex up by extension before any exercise, especially spun out besides animated. But it is and a good idea to stretch each trick. Ask your doctor to bring out you stretches that focus on impulse arthritis trouble spots, such as the knees or the lower back.

3. Walking is always the best exercise

Take a good long walk at least three times a week or participate in a step-aerobics or low-impact action routine sovereign results. crackerjack is no skill that running is bad in that the joints, but remember, it may aggravate an injury if you existent have one. Just remember to check with your tend before archetypal a more exercise program.

The bottom business is that of whole the healthful habits, life is the most important. This is because people are designed to exemplify on assignment. Hence, bodily is actually important for people to exercise in behest to last healthy and keep those joints free from inert and tear.

Just keep domination mind that the unexercised body, even if free from the symptoms of illness or problems like arthritis, is not at its bull dynamism. Hence, start exercising right now!

Exercise May be the Best Medicine for Alzheimers

New research out of the University of Maryland School of Public Health shows that exercise may improve cognitive function in those at risk for Alzheimer’s by improving the efficiency of brain activity associated with memory. Memory loss leading to Alzheimer’s disease is one of the greatest fears among older Americans. While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer’s, for which there currently is no cure.

The study, led by Dr. J. Carson Smith, assistant professor in the Department of Kinesiology, provides new hope for those diagnosed with MCI. It is the first to show that an exercise intervention with older adults with mild cognitive impairment (average age 78) improved not only memory recall, but also brain function, as measured by functional neuroimaging (via fMRI). The findings are published in the Journal of Alzheimer’s Disease.

“We found that after 12 weeks of being on a moderate exercise program, study participants improved their neural efficiency – basically they were using fewer neural resources to perform the same memory task,” says Dr. Smith. “No study has shown that a drug can do what we showed is possible with exercise.”

Recommended Daily Activity: Good for the Body, Good for the Brain

Two groups of physically inactive older adults (ranging from 60-88 years old) were put on a 12-week exercise program that focused on regular treadmill walking and was guided by a personal trainer. Both groups – one which included adults with MCI and the other with healthy brain function – improved their cardiovascular fitness by about ten percent at the end of the intervention. More notably, both groups also improved their memory performance and showed enhanced neural efficiency while engaged in memory retrieval tasks.

The good news is that these results were achieved with a dose of exercise consistent with the physical activity recommendations for older adults. These guidelines urge moderate intensity exercise (activity that increases your heart rate and makes you sweat, but isn’t so strenuous that you can’t hold a conversation while doing it) on most days for a weekly total of 150 minutes.

Measuring Exercise’s Impact on Brain Health and Memory

One of the first observable symptoms of Alzheimer’s disease is the inability to remember familiar names. Smith and colleagues had study participants identify famous names and measured their brain activation while engaged in correctly recognizing a name – e.g., Frank Sinatra, or other celebrities well known to adults born in the 1930s and 40s. “The task gives us the ability to see what is going on in the brain when there is a correct memory performance,” Smith explains.

Tests and imaging were performed both before and after the 12-week exercise intervention. Brain scans taken after the exercise intervention showed a significant decrease in the intensity of brain activation in eleven brain regions while participants correctly identified famous names. The brain regions with improved efficiency corresponded to those involved in the pathology of Alzheimer’s disease, including the precuneus region, the temporal lobe, and the parahippocampal gyrus.

The exercise intervention was also effective in improving word recall via a “list learning task,” i.e., when people were read a list of 15 words and asked to remember and repeat as many words as possible on five consecutive attempts, and again after a distraction of being given another list of words.

“People with MCI are on a very sharp decline in their memory function, so being able to improve their recall is a very big step in the right direction,” Smith states.

The results of Smith’s study suggest that exercise may reduce the need for over-activation of the brain to correctly remember something. That is encouraging news for those who are looking for something they can do to help preserve brain function.

Dr. Smith has plans for a larger study that would include more participants, including those who are healthy but have a genetic risk for Alzheimer’s, and follow them for a longer time period with exercise in comparison to other types of treatments. He and his team hope to learn more about the impact of exercise on brain function and whether it could delay the onset or progression of Alzheimer’s disease.

5 Moderate Exercise Burns Calories

5 Moderate Exercise That Burns Calories - There are many types of exercise you can do to maintain your fitness, now most people choose a relaxing sport, or sports a lightweight, yet can provide a very good effect to health.

Of the various options, many people are now choosing the type of sport that are categorized as being like a tai-chi and yoga. Sports that his impression of this light is able to improve health without the risk of injury and pain. The most fun, sports that still make you sweat flooding this can help reduce weight if done regularly. If you want to have a toned body but do not want struggling in aerobics classes, five of these alternatives you could try.

1. Tai-chi
Calories burned per half hour: 125-150 *.

Tai-chi is often regarded as a sports parent, because of the slow movement. Whereas the movement of this ancient Chinese, originated from the martial arts. Thighs and hips most strongly in his movements, as in high impact aerobic exercise but without the jumps. Its function is to improve strength, balance, concentration, and flexibility, by combining mental discipline and physical movement. If done correctly, tai-chi can also increase your heart rate up to a maximum of 60 percent, so it is considered as a medium exercise.

2. Sport in the water
Calories burned per half hour: 180-200 *.

Exercise in water is usually done by persons who had injury due to high impact exercise. They can walk on a treadmill under water, or a bicep curl, leg, and abdomen. This movement is to burn fewer calories than normal while doing exercises, but many people are so able to work out longer. Water pressure does help blood circulation, so the heart does not have to work too hard.

3. Yoga
Calories burned per half hour: 200 *.

Toga classes is getting a lot to offer, from a well-known in the fitness center to which the shop in the housing. In America, more than four million people are practicing yoga. Sports that comes from ancient Indian philosophy is to improve flexibility, muscle strength, and endurance. Movement is done with a slow (some are dynamic), with a focus to train a deep breath. These poses can be adapted according to fitness level perpetrators. When you have mastered, you can perform postures or movements to form poses that must be retained for 20 minutes. At that time, the benefits increased. Some doctors recommend practicing yoga in a small class, because certain positions can cause injury if not done correctly.

4. Ballet
Calories burned per half hour: 150-180 *.

Supple and graceful dance that is a good way to train the stretch and strengthen muscles that are rarely used, as well as improve flexibility and coordination. As a bonus, your posture will improve. Because a lot of ballet movements, such as the first position (standing upright with the heel of the foot together, toes pointing out, curved arm to the front of the body), forcing you to align the body.

5. Neuromuscular Integrative Action (NIA)
Calories burned per half hour: 150-300 .*

This exercise incorporates dance, ballet, tai-chi, yoga, and martial arts. You must do it without shoes to follow and imitate dance music. A practice session will definitely make you sweat, but not out of breath. This exercise is, unfortunately, only popular in America where there are only 200 to 250 instructors across the country.

Important Exercise Essentials

Getting outfitted with the right pair of shoes or specialized equipment
for your chosen activity helps you relax and feel comfortable.

Comfortable Clothes: Choose garments loose enough to permit a
good range of movement. Choose pure wool base layers for
dryness and comfort. In particular avoid restrictive
waistbands and shoulder straps.

The Right Shoes Are Essential: You need the right shoes for
whichever activity you choose. For activities involving jogging,
running, or jumping, choose cross-training shoes with cushioning
and other built-in features to support the spine.

Take A Towel: If you’re prone to perspiring, take a towel along
to your exercise class. Use it to wipe brow and hands (to
prevent slipping) or as a hygienic layer if you have to lie on shared
mats.

Enlist A Friend: Working out with a buddy is one f the best ways
of maintaining motivation, but don’t let your relationship become
competitive.

THINGS TO REMEMBER:
* Yoga mats should have a sticky finish to prevent slipping.
* Fitness balls can be fun, but learn how to use them with
a trained instructor.
* Choose the right shoes for your activity.

Regular Exercise Face Skin More Healthy

Face Skin More Healthy - Many health benefit that we obtain by exercise. But,, do you know? by exercise also can make ourselves be more beautiful.

According to doctor, that also as beautiful consultant , dr. Fia Fia Lee, by exercise, the bloodstream commonly will increase to all part of body net {tissue}. The benefits for face and skin, the increasing of bloodstream can make the net and skin cells be more healthy.

"With sports, tissues die, quickly replaced with new ones. Therefore, the skin and face look more beautiful, healthy and bright,"

he said on the sidelines AIBI American Series Treadmill Launch in Jakarta, Sunday , (07/31/2011), in Jakarta.

Fia explained, a good workout is this: if you can increase your heart rate up to 40-60 percent of normal conditions. Exercise will also provide benefits if done regularly at least 3 (three) times a week for 30 minutes.

For those who are busy with work, Fia says, there is no reason not to take the time to exercise. This can be tricked by doing it when the weekend with family. "Because if you do not take time to exercise, it will not exercise," he said.

To get a healthy skin and bright, its not enough just to exercise alone. According to the Fia, there is need for other supporting factors such as eating lots of vegetables and fruits that contain vitamin C, drinking water, and adequate sleep (6-8 hours a day).

Fia said, now most of the food choices that exist in the community have turned to fast food (fast food). In fact, such foods should be avoided because besides not good for health, can accelerate premature aging.

One type of fast food menus that should be avoided is that in its processing of food by frying. The oil used for frying are usually continue to be used over and over and contain saturated fats. Thus, when the food enters the body will be bad for health.
