0 Aerobic exercise improves memory brain function and physical fitness

A new study conducted by researchers at the Center for BrainHealth at The University of Texas at Dallas published online in the open-access journal Frontiers in Aging Neuroscience found that engaging in a physical exercise regimen helps healthy aging adults improve their memory, brain health and physical fitness. This finding is significant considering that among adults 50 and older, "staying mentally sharp" outranks social security and physical health as the top priority and concern in the United States.

"Science has shown that aging decreases mental efficiency and memory decline is the number one cognitive complaint of older adults," said Sandra Bond Chapman, Ph.D., founder and chief director of the Center for BrainHealth, Dee Wyly Distinguished University Chair and lead author of the paper. "This research shows the tremendous benefit of aerobic exercise on a persons memory and demonstrates that aerobic exercise can reduce both the biological and cognitive consequences of aging."

For the study, sedentary adults ages 57-75 were randomized into a physical training or a wait-list control group. The physical training group participated in supervised aerobic exercise on a stationary bike or treadmill for one hour, three times a week for 12 weeks. Participants cognition, resting cerebral blood flow, and cardiovascular fitness were assessed at three time points: before beginning the physical exercise regimen, mid-way through at 6 weeks, and post-training at 12 weeks.

"By measuring brain blood flow non-invasively using arterial spin labeling (ASL) MRI, we can now begin to detect brain changes much earlier than before," said Sina Aslan, Ph.D., founder and president of Advance MRI and collaborator on the study. "One key region where we saw increase in brain blood flow was the anterior cingulate, indicating higher neuronal activity and metabolic rate. The anterior cingulate has been linked to superior cognition in late life."

Exercisers who improved their memory performance also showed greater increase in brain blood flow to the hippocampus, the key brain region affected by Alzheimers disease. Chapman pointed out that, using noninvasive brain imaging techniques, brain changes were identified earlier than memory improvements, implicating brain blood flow as a promising and sensitive metric of brain health gains across treatment regimens.

"Physical exercise may be one of the most beneficial and cost-effective therapies widely available to everyone to elevate memory performance," says Dr. Chapman. "These findings should motivate adults of all ages to start exercising aerobically."

Chapman cautioned that while physical exercise is associated with a selective or regional brain blood flow, it did not produce a change in global brain blood flow.

"In another recent study, we have shown that complex mental training increases whole brain blood flow as well as regional brain blood flow across key brain networks," Chapman said. "The combination of physical and mental exercise may be the best health measures to improve overall cognitive brain health. We have just begun to test the upper boundaries of how we can enhance our brains performance into late life. To think we can alter and improve the basic structure of the mature brain through aerobic exercise and complex thinking should inspire us to challenge our thinking and get moving at any age."

0 Physical Inactivity Can Cause Death

Physical Inactivity Can Cause Death - Most of us life and work in busy area, so many people choose to rest and relaxing in-front of TV or just change the activity in sleeping. this lifestyle can trigger the people, if this rarely move lifestyle happen and taken for along time.

Physical inactivity is the term that identified to the people in low of physical activity level or none at all. As a result of combustion energy is not more than 1.5 times the burning energy while resting.

For knowledge, now 48,2 the people on ages more of 10 years is on less of physical activity. Accord to WHO, 60-80% adult population not active in physically.

Physical inactivity is a long time may cause overweight or obese. In the world, obesity ranks fourth leading cause of death or contributed to 30 percent of world mortality.

"From our time 24 hours a day, mostly allocated to inactive. The portion of the most sleep, then work all day sitting in front of the computer. The trip home was also a lot of sitting, at home coupled with watching television and playing video games on weekends,"

said Urip Nuratno, fitness training manager of Fitness First Indonesia.

In fact, to keep in shape, WHO recommends that we exercise at least 30 minutes every day. Sport is meant is that regular physical activity. May we can keep our shape by exercise for 30 minutes a day. Good Luck

0 The Physical Emotional Pregnancy

"Pregnancy is a time to overlook the physical and emotional changes often deep - Merzagora said Francesca, president of Wave -.. Delayed diagnosis of an affective disorder, but may have a significant impact on women and not born" It expects pre smiling mothers, an initiative of the Ministry of Health, to identify the mental health research assistance, services and counseling centers sponsored focused doctors and help treat the disease in the best way, is to make it possible. The information they need. Meanwhile, the wave has a network of centers of Milan, Turin, Pisa, Naples, Catania and Ancona, excellent treatment of this problem.

Several vote inform that depression increases the risk of postpartum depression. Wave power, the National Observatory for Womens Health, the worry about the future and the children of a situation that almost one in four women will be activated. See the results of a survey of the year 2008 and 2011 on 367 women conducted with postpartum depression - 189 178 and pregnant women - Claudio Mencacci, director of the Department of Neurosciences Fatebenefratelli hospital in Milan, said that "investing in health and spiritual mother and child offered strengthening economic recovery Fact., if one of these two areas, as soon as you exit the economic crisis. "

Profile of women at increased risk corresponds to 34 with a good education and the average of the welfare state, married or not married, pregnancy complications and had to deal with anxiety and depression, which receives little support from partners, family and friends do, and the has to do with another growing problem: unemployment. Migrant women, especially when they arrived in Italy for a short time, they are at greater risk as a result of the stress with the acculturation, language and cultural issues that can interfere with the use of social and health services and lack of family support, connected. "The profile shows - by Mencacci - which confirmed to support the importance of the disease and previous work and a family."
