Exercise -
Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body: [11]. Physical exercise can also include training that focuses on accuracy , agility , power , and speed. Types of exercise can also be classified as dynamic or static.
Conversely, static exercise such as weight-lifting can cause the systolic pressure to rise significantly, albeit transiently, during the performance of the exercise. Physical exercise is important for maintaining physical fitness and can contribute to maintaining a healthy weight, regulating the digestive system, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system.
Some studies indicate that exercise may increase life expectancy and the overall quality of life. Most people can increase fitness by increasing physical activity levels. Early motor skills and development is also related to physical activity and performance later in life.
Children who are more proficient with motor skills early on are more inclined to be physically active, and thus tend to perform well in sports and have better fitness levels. Early motor proficiency has a positive correlation to childhood physical activity and fitness levels, while less proficiency in motor skills results in a more sedentary lifestyle.
The type and intensity of physical activity performed may have an effect on a person's fitness level. There is some weak evidence that high-intensity interval training may improve a person's VO2 max slightly more than lower intensity endurance training.
The beneficial effect of exercise on the cardiovascular system is well documented. There is a direct correlation between physical inactivity and cardiovascular disease, 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. Children who participate in physical exercise experience greater loss of body fat and increased cardiovascular fitness. There is a dose-response relationship between the amount of exercise performed from approximately — kcal of energy expenditure per week and all-cause mortality and cardiovascular disease mortality in middle-aged and elderly men.
The greatest potential for reduced mortality is seen in sedentary individuals 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.
Some have suggested that increases in physical exercise might decrease healthcare costs, increase the rate of job attendance, as well as increase the amount of effort women put into their jobs.
Although there have been hundreds of studies on physical exercise and the immune system , there is little direct evidence on its connection to illness.
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 a slightly elevated natural killer cell count and cytolytic action, but these are unlikely to be clinically significant. Vitamin C supplementation has been associated with a 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 survival rates.
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. Exercise may contribute to a reduction of cancer-related fatigue in survivors of breast cancer. There is low-quality evidence for an effect of aerobic physical exercises on anxiety and serious adverse events in adults with hematological malignancies.
The neurobiological effects of physical exercise involve possible 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 consistent exercise over the course of several months.
Aerobic exercise has both 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.
There is some evidence of exercise treatment efficacy for major depressive disorder and attention deficit hyperactivity disorder. Some preclinical evidence and emerging clinical evidence supports the use of exercise as an adjunct therapy for the treatment and prevention of drug addictions.
A number of medical reviews have indicated that exercise has a marked and persistent antidepressant effect in humans, [51] [62] [73] [63] [74] [75] 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.
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: anandamide an endocannabinoid , [79] β-endorphin an endogenous opioid , [80] and phenethylamine a trace amine and amphetamine analog.
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. One study found that exercising improved sexual arousal problems related to antidepressant use.
People who participate in physical exercise experience increased cardiovascular fitness. 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 may be mediated in part by specific neurotrophic factor hormones released into the blood by muscles , including BDNF , IGF-1 , and VEGF.
Community-wide and school campaigns are often used in an attempt to increase a population's level of physical activity. Studies to determine the effectiveness of these types of programs need to be interpreted cautiously as the results vary.
Environmental approaches appear promising: signs that encourage the use of stairs, as well as community campaigns, may increase exercise levels. Such pedestrian zones are part of an effort to combat chronic diseases and to maintain a healthy BMI. Parents can promote physical activity by modelling healthy levels of physical activity or by encouraging physical activity.
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.
The DG EAC regularly publishes a Eurobarometer on sport and physical activity. Worldwide there has been a large shift toward less physically demanding work.
Research published in suggests that incorporating mindfulness into physical exercise interventions increases exercise adherence and 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 a variety of reasons including geographic location and social tendencies. In Colombia, for example, citizens value and celebrate the outdoor environments of their country.
In many instances, they use outdoor activities as social gatherings to enjoy nature and their communities. In Bogotá, Colombia, a mile stretch of road known as the Ciclovía is shut down each Sunday for bicyclists, runners, rollerbladers, skateboarders and other exercisers to work out and enjoy their surroundings.
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 use 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 works particularly well in Sweden due to its geographical location. Exercise in some areas of China, particularly among those who are retired, seems to be socially grounded. In the mornings, square 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 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 , 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.
Exercise has an effect on appetite, but whether it increases or decreases appetite varies from individual to individual, and is affected by the intensity and duration of the exercise. The benefits of exercise have been known since antiquity.
Dating back to 65 BCE, it was Marcus Cicero , Roman politician and lawyer, who stated: "It is exercise alone that supports the spirits, and keeps the mind in vigor.
More recently, exercise was regarded as a beneficial force in the 19th century. In , Archibald MacLaren opened a gymnasium at the University of Oxford and instituted a training regimen for Major Frederick Hammersley and 12 non-commissioned officers.
The first and most significant of these in the UK was the Women's League of Health and Beauty, founded in by Mary Bagot Stack , that had , members in 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.
Animals like chimpanzees , orangutans , gorillas and bonobos , which are closely related to humans, without ill effect engage in considerably less physical activity than is required for human health, raising the question of how this is biochemically possible.
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.

The Journal of Sports Medicine and Physical Fitness. Donating even just a little improves the lives of countless others. Physical activity is anything that moves your body and burns calories. This includes things like walking, climbing stairs and stretching. Think of it as a medium or moderate amount of effort.
Vigorous intensity activities will push your body a little further. They will require a higher amount of effort. Knowing your target heart rate can also help you track the intensity of your activities.
For maximum benefits, include both moderate- and vigorous-intensity activity in your routine along with strengthening and stretching exercises.
Everyone has to start somewhere. Even if you've been sedentary for years, today is the day you can begin to make healthy changes in your life.
Set a reachable goal for today. You can work toward the recommended amount by increasing your time as you get stronger. Don't let all-or-nothing thinking keep you from doing what you can every day. The simplest way to get moving and improve your health is to start walking.
It's free, easy and can be done just about anywhere, even in place. Any amount of movement is better than none. And you can break it up into short bouts of activity throughout the day. Taking a brisk walk for five or ten minutes a few times a day will add up. If you have a chronic condition or disability, talk with your healthcare provider about what types and amounts of physical activity are right for you before making too many changes.
Get started today by simply sitting less and moving more, whatever that looks like for you. Science has linked being inactive and sitting too much with higher risk of heart disease, type 2 diabetes, colon and lung cancers, and early death.

However, people do not need to dedicate large amounts of extra time to exercise to see the benefits. Exercise is sometimes a gradual learning curve. A person should spread sessions across the week and scale up the intensity slowly. It is important for people to ensure they drink plenty of water during and after exercise.
Checking with a doctor is a good precaution to take if someone has a health condition or injury that could impact exercise levels, or that exercise could make worse. While a combination of aerobic and anaerobic exercise provides the most benefit, any exercise is better than none for people who currently have an inactive lifestyle.
Current U. guidelines recommend that people do one of the following:. Toward these goals, it is worth remembering that even minute bursts of physical activity during the day provide health benefits.
