Children who participate in physical exercise experience greater loss of body fat and increased cardiovascular fitness. 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.
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. Although there have been hundreds of studies on physical exercise and the immune system , there is little direct evidence on its connection to illness. Epidemiological evidence suggests that moderate exercise has a beneficial effect on the human immune system ; an effect which is modeled in a J curve.
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. Vitamin C supplementation has been associated with lower incidence of upper respiratory tract infections in marathon runners.
Biomarkers of inflammation such as C-reactive protein , which are associated with chronic diseases, are reduced in active individuals relative to sedentary individuals, and the positive effects of exercise may be due to its anti-inflammatory effects. In individuals with heart disease, exercise interventions lower blood levels of fibrinogen and C-reactive protein, an important cardiovascular risk marker.
A systematic review evaluated 45 studies that examined the relationship between physical activity and cancer survivorship. According to the review, "[there] was consistent evidence from 27 observational studies that physical activity is associated with reduced all-cause, breast cancer—specific, and colon cancer—specific mortality. There is currently insufficient evidence regarding the association between physical activity and mortality for survivors of other cancers. The neurobiological effects of physical exercise are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition.
In healthy adults, aerobic exercise has been shown to induce transient effects on cognition after a single exercise session and persistent effects on cognition following regular exercise over the course of several months. Aerobic exercise induces short- and long-term effects on mood and emotional states by promoting positive affect , inhibiting negative affect , and decreasing the biological response to acute psychological stress.
Regular aerobic exercise improves symptoms associated with a variety of central nervous system disorders and may be used as an adjunct therapy for these disorders. There is clear evidence of exercise treatment efficacy for major depressive disorder and attention deficit hyperactivity disorder. A number of medical reviews have indicated that exercise has a marked and persistent antidepressant effect in humans,       an effect believed to be mediated through enhanced BDNF signaling in the brain. The Cochrane Collaboration review on physical exercise for depression noted that, based upon limited evidence, it is more effective than a control intervention and comparable to psychological or antidepressant drug therapies.
A review of clinical evidence which included a medical guideline for the treatment of depression with exercise noted that the available evidence on the effectiveness of exercise therapy for depression suffers from some limitations;  nonetheless, it stated that there is clear evidence of efficacy for reducing symptoms of depression. Continuous aerobic exercise can induce a transient state of euphoria , colloquially known as a "runner's high" in distance running or a "rower's high" in crew , through the increased biosynthesis of at least three euphoriant neurochemicals: Preliminary evidence from a review indicated that physical training for up to four months may increase sleep quality in adults over 40 years of age.
Too much exercise can be harmful. Without proper rest, the chance of stroke or other circulation problems increases,  and muscle tissue may develop slowly. 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,  whereas the effects of increased exposure to air pollution seem only a minor concern.
In extreme instances, over-exercising induces serious performance loss. Unaccustomed overexertion of muscles leads to rhabdomyolysis damage to muscle most often seen in new army recruits. One result of detrimental overtraining is suppressed immune function, with an increased incidence of upper respiratory tract infection URTI. Stopping excessive exercise suddenly may create a change in mood. Exercise should be controlled by each body's inherent limitations.
While one set of joints and muscles may have the tolerance to withstand multiple marathons , another body may be damaged by 20 minutes of light jogging. This must be determined for each individual. Too much exercise may cause a woman to cease menstruation, a symptom known as amenorrhea. Resistance training and subsequent consumption of a protein-rich meal promotes muscle hypertrophy and gains in muscle strength by stimulating myofibrillar muscle protein synthesis MPS and inhibiting muscle protein breakdown MPB. Aerobic exercise induces mitochondrial biogenesis and an increased capacity for oxidative phosphorylation in the mitochondria of skeletal muscle, which is one mechanism by which aerobic exercise enhances submaximal endurance performance.
Developing research has demonstrated that many of the benefits of exercise are mediated through the role of skeletal muscle as an endocrine organ.
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.
The effects of physical exercise on the central nervous system are mediated in part by specific neurotrophic factor hormones that are released into the blood stream by muscles , including BDNF , IGF-1 , and VEGF. Multiple component community-wide campaigns are frequently used in an attempt to increase a population's level of physical activity. A Cochrane review, however, did not find evidence supporting a benefit. Environmental approaches appear promising: Such pedestrian zones are part of an effort to combat chronic diseases and to maintain a healthy BMI.
To identify which public health strategies are effective, a Cochrane overview of reviews is in preparation. Physical exercise was said to decrease healthcare costs, increase the rate of job attendance, as well as increase the amount of effort women put into their jobs. Children will mimic the behavior of their parents in relation to physical exercise. Parents can thus promote physical activity and limit the amount of time children spend in front of screens.
Overweight children who participate in physical exercise experience greater loss of body fat and increased cardiovascular fitness.
According to the Centers for Disease Control and Prevention in the United States, children and adolescents should do 60 minutes or more of physical activity each day. Financing is available for increased collaboration between players active in this field across the EU and around the world, the promotion of HEPA in the EU and its partner countries and the European Sports Week. Worldwide there has been a large shift towards less physically demanding work. Research in indicates integrating mindfulness to physical exercise interventions increases exercise adherence, self-efficacy and also has positive effects both psychologically and physiologically.

Exercising looks different in every country, as do the motivations behind exercising. People may exercise for personal enjoyment, health and well-being, social interactions, competition or training, etc. These differences could potentially be attributed to geographic location, social tendencies, or otherwise.
In Colombia, citizens value and celebrate the outdoor environments of their country. In many instances, they utilize outdoor activities as social gatherings to enjoy nature and their communities. Similarly to Colombia, citizens of Cambodia tend to exercise socially outside.
In this country, public gyms have become quite popular. People will congregate at these outdoor gyms not only to utilize the public facilities, but also to organize aerobics and dance sessions, which are open to the public. Sweden has also begun developing outdoor gyms, called utegym.
These gyms are free to the public and are often placed in beautiful, picturesque environments. People will swim in rivers, use boats, and run through forests to stay healthy and enjoy the natural world around them. This is especially possible in Sweden due to its geographical location. Chinese exercise, particularly in the retired community, seems to be socially grounded. In the mornings, dances are held in public parks; these gatherings may include Latin dancing, ballroom dancing, tango, or even the jitterbug.
Dancing in public allows people to interact with those with whom they would not normally interact, allowing for both health benefits and social benefits. These sociocultural variations in physical exercise show how people in different geographic locations and social climates have varying motivations and methods of exercising. Physical exercise can improve health and well-being, as well as enhance community ties and appreciation of natural beauty.
Proper nutrition is as important to health as exercise. 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.

Active recovery is recommended after participating in physical exercise because it removes lactate from the blood more quickly than inactive recovery. 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. The benefits of exercise have been known since antiquity.
More recently, exercise was regarded as a beneficial force in the 19th century. After , Archibald MacLaren opened a gymnasium at the University of Oxford and instituted a training regimen for 12 military officials at the university. This regimen was later assimilated into the training of the British Army. The link between physical health and exercise or lack of it was further established in and reported in by a team led by Jerry Morris. 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: Studies of animals indicate that physical activity may be more adaptable than changes in food intake to regulate energy balance.
Mice having access to activity wheels engaged in voluntary exercise and increased their propensity to run as adults. The effects of exercise training appear to be heterogeneous across non-mammalian species. As examples, exercise training of salmon showed minor improvements of endurance,  and a forced swimming regimen of yellowtail amberjack and rainbow trout accelerated their growth rates and altered muscle morphology favorable for sustained swimming.

Practice each hand separately first. Practice this exercise slowly in the beginning metronome on If you played it easily, and precisely with the metronome, move the tempo up one notch.
Continue to practice in this way until you reach bpm. Practice with various dynamics. Practice soft, loud and everything in between. As you practice, vary the touch. Play staccato, play legato, and play two-note slurs. Practice in different rhythms. In this case, however, the principal melody is in the left hand, the secondary being embedded in the arpeggios of the right hand. The first section bars 1—28 features a right-hand figuration that is straightforward with the accent falling always on the first note of each group of four semiquavers throughout the work.
The main difficulty is that they must be played forte and legato at speed, ascending and descending sequentially over the keyboard. Due to the obligation to sustain the left-hand melody somehow whilst still keeping the right hand's figure clear, this presents a great difficulty.
The central section bars 29—60 features elaborations on the original figuration. The D minor lasts only 7 bars before undergoing an extended series of modulations right through to bar 60 — the return to the main theme.
