Physical exercise - Wikipedia, the free encyclopedia. Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. Frequent and regular physical exercise boosts the immune system and helps prevent . Some care providers call exercise the . Conversely, static exercise (such as weight- lifting) can cause the systolic pressure to rise significantly (during the exercise). Health effects. Some studies indicate that exercise may increase life expectancy and quality of life. There is a direct correlation between physical inactivity and cardiovascular mortality, and physical inactivity is an independent risk factor for the development of coronary artery disease. Low levels of physical exercise increase the risk of cardiovascular diseases mortality. The greatest potential for reduced mortality is in the sedentary who become moderately active. Studies have shown that since heart disease is the leading cause of death in women, regular exercise in aging women leads to healthier cardiovascular profiles. Most beneficial effects of physical activity on cardiovascular disease mortality can be attained through moderate- intensity activity (4. Persons who modify their behavior after myocardial infarction to include regular exercise have improved rates of survival. Persons who remain sedentary have the highest risk for all- cause and cardiovascular disease mortality. It increases HDL cholesterol, insulin sensitivity, and exercise tolerance. Epidemiological evidence suggests that moderate exercise has a beneficial effect on the human immune system; an effect which is modeled in a J curve. Moderate exercise has been associated with a 2. URTI), but studies of marathon runners found that their prolonged high- intensity exercise was associated with an increased risk of infection occurrence. However, another study did not find the effect. Immune cell functions are impaired following acute sessions of prolonged, high- intensity exercise, and some studies have found that athletes are at a higher risk for infections. Studies have shown that strenuous stress for long durations, such as training for a marathon, can suppress the immune system by decreasing the concentration of lymphocytes. Athletes may have slightly elevated natural killer cell count and cytolytic action, but these are unlikely to be clinically significant. In individuals with heart disease, exercise interventions lower blood levels of fibrinogen and C- reactive protein, an important cardiovascular risk marker. According to the study results . There is clear evidence of exercise treatment efficacy for major depressive disorder. The optimum time to exercise may be 4 to 8 hours before bedtime, though exercise at any time of day is beneficial, with the possible exception of heavy exercise taken shortly before bedtime, which may disturb sleep. There is, in any case, insufficient evidence to draw detailed conclusions about the relationship between exercise and sleep. Sleeping pills are more costly than to make time for a daily routine of staying fit, and may have dangerous side effects in the long run. Exercise can be a healthy, safe and inexpensive way to achieve more and better sleep. Without proper rest, the chance of stroke or other circulation problems increases. Extremely intense, long- term cardiovascular exercise, as can be seen in athletes who train for multiple marathons, has been associated with scarring of the heart and heart rhythm abnormalities. These changes further result in myocardial cell damage in the lining of the heart, leading to scar tissue and thickened walls. During these processes, the protein troponin increases in the bloodstream, indicating cardiac muscle cell death and increased stress on the heart itself. For many activities, especially running and cycling, there are significant injuries that occur with poorly regimented exercise schedules. Injuries from accidents also remain a major concern.

To lose weight, is actually very imperative to attempt so, not merely by doing diets, or exercise programs, which. Unaccustomed overexertion of muscles leads to rhabdomyolysis (damage to muscle) most often seen in new army recruits. One sign of Overtraining Syndrome (OTS) is suppressed immune function, with an increased incidence of upper respiratory tract infection (URTI). An increased incidence of URTIs is also associated with high volume/intensity training, as well as with excessive exercise (EE), such as in a marathon.

While one set of joints and muscles may have the tolerance to withstand multiple marathons, another body may be damaged by 2. This must be determined for each individual. Too much exercise may cause a woman to miss her periods, a symptom known as amenorrhea. That is, contracting muscles release multiple substances known as myokines which promote the growth of new tissue, tissue repair, and multiple anti- inflammatory functions, which in turn reduce the risk of developing various inflammatory diseases. Ventricular hypertrophy, the thickening of the ventricular walls, is generally beneficial and healthy if it occurs in response to exercise. Central nervous system. A 2. 01. 5 Cochrane review, however, did not find evidence supporting a benefit. These pedestrian zones are part of an effort to combat chronic diseases, including obesity. Parents can thus promote physical activity and limit the amount of time children spend in front of screens which may decrease the risk of childhood obesity. According to the Centers for Disease Control and Prevention in the United States, both children and adults should do 6. When exercising, it becomes even more important to have a good diet to ensure that the body has the correct ratio of macronutrients while providing ample micronutrients, in order to aid the body with the recovery process following strenuous exercise. Removing lactate from circulation allows for an easy decline in body temperature, which can also benefit the immune system, as an individual may be vulnerable to minor illnesses if the body temperature drops too abruptly after physical exercise. Marcus Cicero, around 6. BCE, stated: . The first and most significant of these in the UK was the Women's League of Health and Beauty founded in 1. Mary Bagot Stack that had 1. Morris noted that men of similar social class and occupation (bus conductors versus bus drivers) had markedly different rates of heart attacks, depending on the level of exercise they got: bus drivers had a sedentary occupation and a higher incidence of heart disease, while bus conductors were forced to move continually and had a lower incidence of heart disease.

Research in children finds that higher fit and more active preadolescent children show greater hippocampal and basal ganglia volume, greater white matter integrity, elevated and more efficient patterns of brain activity, and superior cognitive performance and scholastic achievement. Higher fit and more physically active older adults show greater hippocampal, prefrontal cortex, and basal ganglia volume, greater functional brain connectivity, greater white matter integrity, more efficient brain activity, and superior executive and memory function. Summaries of these studies can now be found in several meta- analyses, most of which confirm that PA positively influences cognitive function in late adulthood with small to moderate sized effects . In a meta- analysis of 1. PA trials, engaging in moderate intensity PA resulted in enhanced cognitive function across all cognitive domains examined, but with the largest effect sizes for indices of executive function . Meta- analyses of longitudinal observational studies have also confirmed that self- reported engagement in PA is associated with nearly a 4. These, and other studies, make a convincing argument that both continuing to engage in, and starting to engage in, PA in late adulthood may have a profound effect on maintaining cognitive health, improving function, and reducing the risk of developing cognitive impairment. Brain structure: There have been now more than 3. PA or fitness on brain structure in older adults (> 6. Such effects are important since increasing age is associated with brain atrophy and loss of volume, which precedes and predicts conversion to dementia. Higher aerobic fitness levels have been associated with larger gray matter volumes in older adults in several areas including the frontal cortex . Longitudinal observational studies have also shown that greater amounts of PA are associated with larger gray matter volumes in these regions, and greater volume is, in turn, associated with a reduced risk of cognitive impairment . These cross- sectional and observational results in older adults are further supported by clinical trials that have shown that six- months to one- year of regular PA is associated with an increase in both frontal cortex . These effects on gray matter volume are accompanied by differences found in white matter integrity.
