Poor Physical Performance in Adults, a Predictor of Future Disability
Exercise has many benefits. Our bodies thrive on regular physical activity. Exercise provides both physical and emotional rewards. Exercise can decrease your blood pressure,total blood cholesterol, decrease your blood sugar.These physical effects decrease the risk of stroke, heart disease, and diabetes. Exercise can also help you lose weight or keep a healthy weight.Among the emotional benefits of exercise may improve sense of well-being,increased physical and emotional stamina, improved sleep.Exercise also affects our brain chemistry. For example, exercise can help treat mild depression. It can also help you have more energy.
Sedentary habits, especially TV watching, are associated with significantly higher risks for obesity and type 2 diabetes. Regular exercise, even of moderate intensity (such as brisk walking), improves insulin sensitivity and may play a significant role in preventing type 2 diabetes -- regardless of weight loss. An important study reported a 58% lower risk for type 2 diabetes in adults who performed moderate exercise for as little as 2.5 hours a week.People with diabetes are at particular risk for heart disease,improves insulin sensitivity.So the heart-protective effects of aerobic exercise are especially important.
A high waist circumference can be one sign of a condition called Metabolic Syndrome. Although most people have never heard of it, this syndrome is quite common; it affects about one out of every four adults in the United States.Metabolic Syndrome often progresses to type 2 diabetes—and treating the syndrome can help prevent this form of diabetes. The higher your peak bone mass, the less likely you'll be to have fractures later in life. Maximum peak bone mass depends partly on your inherited ability to make bone, the amount of calcium you consume and your exercise level. Weight-bearing exercises, such as walking, apply tension and pressure to your muscles and bones, encouraging your body to increase bone density to meet the additional stress.
Bronchoconstriction was evidence by increased airway resistance, decreased forced expiratory volume (FEV), and symptoms such as chest tightness, shortness of breath and wheezing. In some severe occasion, bronchoconstriction required removal of exposure, medical intervention, or both. Mild to moderate asthmatic children and adults are at greatest risk for short-term SO2-induced respiratory effects. Severe asthmatic patients are at lower risk because of their low exercise tolerance which would deter them from engaging in activities that make them vulnerable to attacks.
Weight loss to improve cardiovascular health is a high priority of the American Heart Association because approximately 34% of the population is overweight. There is a great deal of public, commercial, and medical interest in promoting long-term weight loss programs. The AHA Nutrition Committee has been asked to provide general guidelines for weight management programs for healthy adults.The proposed dietary changes, the most important of which is reduction of total fat and saturated fat intake, should be both pleasant and acceptable, and the increased physical activity should be enjoyable, practical, and safe. People who have difficulty maintaining a normal weight should be evaluated by a physician, especially if they are very overweight or have been unsuccessful in weight loss programs.
In one study, regular aerobic exercise increased HDL cholesterol by 3 percent to 9 percent in otherwise healthy sedentary adults. Try to get at least 30 to 60 minutes of aerobic activity on most days of the week. Better yet, exercise every day. Take a brisk daily walk. Ride your bike. Swim laps. If you can't fit in a long workout, break it up into smaller sessions spread throughout the day.
Diabetes and conditions that put people at risk for diabetes, blood pressure regulation, risks of falling and balance problems, and the impact of exercise on strength, endurance, mobility, and health conditions. Exercises that stretch and strengthen the muscles of your abdomen and spine can help prevent back problems. If your back and abdominal muscles are strong, it will help you to maintain good posture and keep your spine in its correct position.
A test for rheumatoid factor, an antibody produced in the blood of children with some forms of JRA. But it's much more commonly found in adults with rheumatoid arthritis.When pain strikes, it's natural for your child to want to sit still. But it's important to maintain a regular exercise program. Muscles must be kept strong and healthy so they can help support and protect joints. Regular exercise also helps to maintain range of motion.An appropriate physical therapy program is essential in the management of any type of arthritis.
Excess pounds take a toll on HDL cholesterol. But there's good news. If you're overweight, losing even a few pounds can improve your HDL level. For every 2 pounds you lose, your HDL may increase by .35 mg/dL. That's about 1 mg/dL for every 6 pounds. To keep your weight in a healthy range, focus on permanent changes to your eating and exercise habits. Motivate yourself by remembering the benefits of losing weight, such as a healthier heart, more energy and improved self-esteem.
Staying trim and healthy in younger years can lead to a healthier, more mobile old age, U.S. researchers say.
Researchers analyzed data on more than 2,800 people, ages 70 to 79, in the Pittsburgh and Memphis metropolitan areas.
Reporting in the International Journal of Obesity, they found that women and men who were obese at ages 25 and 50, as well as at the time of the study, scored significantly lower on physical performance tests than those who were normal weight at those ages.
The physical performance tests measured walking speed, balance, and the ability to rise from a chair. The researchers noted that poor physical performance in older adults is a predictor of future disability, nursing home admission and death.
Women who were overweight but not obese at ages 25, 50 and between 70 to 79 also had lower physical performance test scores than those with normal weights at those ages.
The study also found that men and women who were overweight or obese in early- to mid-adulthood had lower scores than those who became overweight or obese in late-adulthood.
There may be a number of reasons for these findings, said lead author Denise K. Houston, an instructor in internal medicine-gerontology at the Wake Forest University School of Medicine in Winston-Salem, N.C.
"Obesity may lead to joint wear and tear, reduced exercise capacity, and a higher rate of chronic diseases such as cardiovascular disease, diabetes, and arthritis that can result in physical disability," Houston said in a prepared statement.
"Obesity in young and middle adulthood may result in earlier onset of chronic diseases and lower physical activity, contributing to decreased muscle strength and cardiovascular fitness and greater declines in physical performance," she said.
According to Houston, the findings suggest that "interventions to prevent overweight and obesity in young and middle-age adults may be useful in preventing or delaying the onset of physical disability later in life."
The Start! movement is here to motivate and encourage all Americans to take up walking and other healthy habits as part of their daily routine all year around, and to live longer, stronger heart-healthy lives.Every year in the United States, about 300,000 adults die from causes related to excess body weight.it is time for us to make a comparable change in the way we eat. This type of change is needed in order to address the epidemic of overweight and obesity in the United States.Overweight and obesity that begins in childhood often continues into adulthood, leading to increased risks for heart disease, high blood pressure, and other serious medical conditions. Exercise is critical for strong muscles and bones. Muscle strength declines as people age, but studies report that when people exercise they are stronger and leaner than others in their age group.
Exercise helps them lower their risk of chronic pain in the future. Exercise capacity is a more powerful predictor of mortality among men than other established risk factors for cardiovascular disease.Physical exercise has consistently been identified as a central element of rehabilitation for many chronic diseases and has been successful in improving quality of life and reducing all-cause mortality. Recent observational evidence suggests that moderate levels of physical activity may even reduce the risk of death from breast cancer, and therefore exercise may prove to be a valuable intervention to improve not only quality of life but overall survival.
Exercise increases the oxidation of essential amino acids and increases the requirement for dietary protein, resistance exercise results in a decrease in nitrogen excretion, lowering dietary protein needs. This increased efficiency of protein use may be important for wasting diseases such as HIV infection and cancer and particularly in elderly people suffering from sarcopenia.Healthy lifestyle habits including mental stimulation, physical exercise, good nutrition, stress management, and sleep can improve brain fitness.
Walking has the lowest drop out rate of any physical activity, and is the simplest positive change individuals can make to effectively improve their heart health.As a matter of fact, you can gain about two hours of life expectancy for each hour of regular exercise, even if you don’t start until middle age.
