Fitness Tips For Health

IS THERE AN IDEAL AGE FOR FITNESS?

Many studies have been conducted in old folks, but the changes in Neurogenesis and interconnection are just as dramatic as in young people. There seem to be more long lasting effects while the brains are still developing. For instance in children with ADHD, exercises may be a substitute or a supplement for drugs.  In general until about 20 years of age, the frontal lobes are not completely developed and exercises may speed up the executive functions, math, logic, reading, etc.  That knowledge from kids is making many educators to request more P.T in schools.  The hope of educators is that kids can develop a love for sports early in life to avoid the fate that their grandparents are now facing due to physical inactivity.  Current and early studies suggest that people that exercise, delay or suppress the development of Alzheimer Disease.

HOW MUCH, HOW OFTEN AND WHAT MODALITY OF EXERCISE IS APPROPRIATE?

Researchers don’t know the straight answer yet. So far the strength training, toning and weight lifting, have no effect on cognition.  There is no consensus about how much is too much. Recent discoveries have shown long lasting effects that include: improved mood decreased anxiety, improved sleep pattern, reduced stress and elevated self-‘esteem. That is why some people call it “endorphin high”, that make you feel good during and right after the exercise session. It is kind of the “Prozac”, “Ritalin” effect.

DOES THE BRAIN CAN TELL HOW MUCH EXERCISE  IS SUFFICIENT?

The motivation for exercises is still under genetic control.  Recent studies indicate that the brain governs how much activity the body is ready for, just similar to how make people hungry  to become overweight.  The brain uses signals from the muscles as a guide. Therefore the brain of lazy people often encourages some inactivity.  Indeed, some researchers are beginning to wonder if genes that make a person vulnerable to depression also make exercise less pleasant.  Perhaps this may explain why is almost impossible to promote a healthy lifestyle, as information about the positive effects of exercises is not enough.  People just hate exercises.  Perhaps would be better to explain how the genes control our experience of exercise. Start knowing yourself first, before taking the decision to join a fancy gym, to invest in expensive equipment to obtain the benefit of exercise.

Remember that an aggressive, intense, vigorous program won’t give an instantaneous psychological improvement.  More important is the ability to achieve a sustained exercise routine. The research indicates that one have to stick to a chosen program for atleast 2 months to see the best chances to feel better. Develop a habit that with time becomes enjoyable to continue.

CHANGING FROM FAT TO FIT

When we exercise, we don’t benefit our body muscles, but our heart muscles and our brain neurons do.

TYPE OF EXERCISES

  • Aerobics
  • Strength training
  • Aerobics stimulates the CVS rushing blood to the ear, the brain and the rest of the body.
  • Strength training can reduce and sometimes reverse some of the body decline of bone and muscle mass.

LIVE LONGER

According to a study done on 17000 middle age Harvard Graduates, found that those individuals who exercised on regular basis, reduced the risk of dying prematurely by 25%. Other studies on people older than 50, who exercised, lived between 1.3 to 3.7 years longer than the sedentary ones. The more vigorous the physical activity the longer the prolongation of life.

HEAL FASTER

Research at the Ohio State University found after dividing 35-70 years of age in 2 groups. Group one attended a supervised exercise program for weeks.  The second group sedentary people as model. At the end of the first month, they produce wounds on the arms of both groups as volunteers, then monitored the speed of healing in both groups. The wounds of those who exercised healed about 25% faster

INCREASE SEXUAL FUNCTION

On average, by age 50, one third of Americans men, suffer some form of impotence. Newer drugs such as Viagra and Cialis help erectile dysfunction by increasing blood now to the penis , but studies have found the exercises are more long lasting beneficial in those who participated in frequent vigorous exercises  were at least one third less likely to suffer erectile dysfunction.

HAVE FEWER HOT FLASHES

About 75% of women in the US experience hot flashes during menopause and 25% still get them even ten or more years afterward.  1 n the past the medical health providers eated this condition with hormone replacement, giving Estrogens and Progesterone. But starting in 2002, millions of women discontinue such hormone therapy due to many undesirable side effects.  A study done in 1998 a Swedish researcher studied 800 women ages 55-56 and found that those who exercised at least 2 hours a week experienced less hot flashes. It has been postulated that one reason might be the release of Endorphins that may counter the hormonal imbalance that produce these menopausal symptoms.

BE PAIN FREE

Although exercises alone cannot eliminate all the aches and pains of getting older, it can reduce muscle, tendon, bone and joint pains. Researchers at Stanford University compared group of 60 plus of runners  with a group of sedentary elders; they found that after adjusting for age, height, gender and health status, the runners experienced less musculoskeletal pains over 14 years.

SAVE MONEY

Chronic diseases cost the US, billions of dollars in health care and lost productivity every year. But a study by the Health Partner Research Foundation has found that people older than 50 that exercise for at least 30 minutes 3 times a week, actually saved an average of 2200 dollars a year in medical bills.

SOME SCIENTIFIC EVIDENCE OF REGULAR PHYSICAL EXERCISES

“Physical activity can save your eye sight” say the experts at the Wisconsin University. Physical Activity lowers the risk of age-related macular degeneration by as much as 70%. The exercise may control inflammation and blood vessel abnormalities that have been linked to the disease.

Exercises can make you “smarter”. Experiments with fifth grade children put to PE by Charles Hillerman, concluded that sports boost student’s intellect. There is rapidly growing movement showing that Exercise can make people smarter. Recently  some researchers have announced they have coaxed the human brain into growing new nerve cells (neurons), simply by putting subjects on a three-month aerobic work-out regimen. Other researchers have found that vigorous exercises  can make existing neurons to form a dense , interconnected webs that make the brain function faster and more efficient.

There are now clues, that physical activity can prevent dementia like Alzheimer’s, Attention Deficit (ADHD) and other cognitive disorders. These and other facts about Sports and Scholar Achievements are really not new. We know it was common in ancient Greece in which fitness and learning was equally important. The Greek knew there was connection between “mind and body” when they stated “mens Sana et corpora Sana”. We now realize that aerobics makes the heart pump more oxygen to the brain and the rest of the body. With the help of brain scanning tools and knowledge of biochemistry, researchers have found that the effects of exercises are more profound and complex than previously thought.

Every time a muscle contracts and rests, sends out chemicals, including a protein called IGF-1 , that travels through the blood stream into the brain. IGF-1 acts as mediator of the body’s neurotransmitter factory. IGF-1 stimulates the production of other chemicals including BDF (Brain Derived Neurotrophic Factor). Raten, author of an incoming book “SPARK” calls BDNF a “miracle-grow” for the brain. With habitual aerobics the neuron starts to branch out to produce webs to communicate each other in new ways. In other words, the more abundant the BDNF is, the greater the capacity to learn. Most individuals can keep BDNF pool fairly constant throughout the adulthood; but as they age their individual neurons start to die off slowly. Until about 10 years ago scientists were convinced that the loses were permanent; that those dead neurons were not able to be replaced by the brain. But new research in animal models has shown the neurogenesis thus occur, especially in certain parts of the brain through aerobic exercises. It has been shown that the STEM CELLS do transform into full-grown, functional neurons. Most of the neurogenesis has been observed by Scott Small at Columbia University and Fred Isage, a neurobiologist al Salk Institute in the Dentate Gyrus, a region of the Hippocampus by way of creation of blood vessels (vasogenesis).

The Hippocampus which is located under the Temporal Lobes helps the brain to match names to faces.  As the psychologist Arthur Kramer puts it, physical activity not only slows down the aging process but perhaps a matter of reversing it. The other area of interest is the executive function of the Frontal Lobes the site of higher thoughts, decision making, planning and so forth. In general new growth of neuron can happen throughout the rest of the brain.

Furthermore, new population of neurons also means new population of blood vessels, thus reducing the chance of some multiple frequent and silent ischemic events leading to strokes that are usually silent and contribute to declining cognition.

Other researchers have found that athletes have more abundant Atrocities, the kind of cells that support the neurons conducting the neurotransmitter chemicals that convey messages from cell to cell. Among those neurotransmitters are DA, Serotonin (5-HT),NE. So doing a work up, helps with the concentration, release and increasing impulsivity

The nice thing about exercises is that we don’t have to wait several weeks to feel the benefit of neurogenesis; many additional benefits from them appear almost immediately, as early as 30 minutes and continue serendipitously during the rest of the day.

Individuals feel the sensation of well being, enthusiasm, confidence, etc. It is important to know that the commitment for fitness needs to be maintained, so the neurogenesis and its connection remain the same through the years when the training stops, the astrocite web starts to decline again.
