Weight training

Exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness.[1]

It is performed for various reasons, to aid growth and improve strength, preventing aging, developing muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, improving health[2] and also for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and enhance well-being.[3]

In terms of health benefits, the amount of recommended exercise depends upon the goal, the type of exercise, and the age of the person. Even doing a small amount of exercise is healthier than doing none.[4]

Classification

Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body:[5]

Physical exercise can also include training that focuses on accuracy, agility, power, and speed.[9]

Types of exercise can also be classified as dynamic or static. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly, albeit transiently, during the performance of the exercise.[10]

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.[12] People who participate in moderate to high levels of physical exercise have a lower mortality rate compared to individuals who by comparison are not physically active.[13] Moderate levels of exercise have been correlated with preventing aging by reducing inflammatory potential.[14] The majority of the benefits from exercise are achieved with around 3500 metabolic equivalent (MET) minutes per week, with diminishing returns at higher levels of activity.[15] For example, climbing stairs 10 minutes, vacuuming 15 minutes, gardening 20 minutes, running 20 minutes, and walking or bicycling for transportation 25 minutes on a daily basis would together achieve about 3000 MET minutes a week.[15] A lack of physical activity causes approximately 6% of the burden of disease from coronary heart disease, 7% of type 2 diabetes, 10% of breast cancer and 10% of colon cancer worldwide.[16] Overall, physical inactivity causes 9% of premature mortality worldwide.[16]

Fitness

Main article: Physical fitness

Individuals can increase fitness following increases in physical activity levels.[17] Increases in muscle size from resistance training is primarily determined by diet and testosterone.[18] This genetic variation in improvement from training is one of the key physiological differences between elite athletes and the larger population.[19][20] Studies have shown that exercising in middle age leads to better physical ability later in life.[21]

Early motor skills and development have also shown to be related to physical activity and performance later in life. Children who have more proficient motor skills early on are more inclined to being 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 tendency to partake in a more sedentary lifestyle.[22]

A 2015 meta-analysis demonstrated that high-intensity interval training improved one's VO2 max more than lower intensity endurance training.[23]

Cardiovascular system

Main article: Cardiovascular fitness

The beneficial effect of exercise on the cardiovascular system is well documented. 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.[24]

Children who participate in physical exercise experience greater loss of body fat and increased cardiovascular fitness.[25] Studies have shown that academic stress in youth increases the risk of cardiovascular disease in later years; however, these risks can be greatly decreased with regular physical exercise.[26] There is a dose-response relation between the amount of exercise performed from approximately 700–2000 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 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 (40–60% of maximal oxygen uptake, depending on age). 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.[27] According to the American Heart Association, exercise reduces the risk of cardiovascular diseases, including heart attack and stroke.[24]

Immune system

Although there have been hundreds of studies on physical exercise and the immune system, there is little direct evidence on its connection to illness.[28] 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 29% decreased incidence of upper respiratory tract infections (URTI), but studies of marathon runners found that their prolonged high-intensity exercise was associated with an increased risk of infection occurrence.[28] 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.[29] The immune systems of athletes and nonathletes are generally similar. Athletes may have slightly elevated natural killer cell count and cytolytic action, but these are unlikely to be clinically significant.[28]

Vitamin C supplementation has been associated with lower incidence of upper respiratory tract infections in marathon runners.[28]

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.[30] The depression in the immune system following acute bouts of exercise may be one of the mechanisms for this anti-inflammatory effect.[28]

Cancer

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."[31] Evidence suggests that exercise may positively affect cancer survivors health-related quality of life, including factors such as anxiety, self-esteem and emotional well-being.[32] For people with cancer undergoing active treatment, exercise may also have positive effects on health-related quality of life, such as fatigue and physical functioning.[33] This is likely to be more pronounced with higher intensity exercise.[33] Although there is only limited scientific evidence on the subject, people with cancer cachexia are encouraged to engage in physical exercise.[34] Due to various factors, some individuals with cancer cachexia have a limited capacity for physical exercise.[35][36] Compliance with prescribed exercise is low in individuals with cachexia and clinical trials of exercise in this population often suffer from high drop-out rates.[35][36]

The neurobiological effects of physical exercise involve possible interrelated effects on brain structure, brain function, and cognition.[37][38][39][40] Research in humans has demonstrated that consistent aerobic exercise (e.g., 30 minutes every day) may induce improvements in certain cognitive functions, neuroplasticity and behavioral plasticity; some of these long-term effects may include increased neuron growth, increased neurological activity (e.g., c-Fos and BDNF signaling), improved stress coping, enhanced cognitive control of behavior, improved declarative, spatial, and working memory, and structural and functional improvements in brain structures and pathways associated with cognitive control and memory.[41][42][43] The effects of exercise on cognition may affect academic performance in children and college students, improve adult productivity, preserve cognitive function in old age, preventing or treating certain neurological disorders, and improving overall quality of life.[44][45][46][47]

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.[37][43][48] People who regularly perform an aerobic exercise (e.g., running, jogging, brisk walking, swimming, and cycling) have greater scores on neuropsychological function and performance tests that measure certain cognitive functions, such as attentional control, inhibitory control, cognitive flexibility, working memory updating and capacity, declarative memory, spatial memory, and information processing speed.[41][43][48][49][50]

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.[48] Aerobic exercise may affect both self-esteem and overall well-being (including sleep patterns) with consistent, long term participation.[51] Regular aerobic exercise may improve symptoms associated with central nervous system disorders and may be used as adjunct therapy for these disorders. There is some evidence of exercise treatment efficacy for major depressive disorder and attention deficit hyperactivity disorder.[45][52][53][54] The American Academy of Neurology's clinical practice guideline for mild cognitive impairment indicates that clinicians should recommend regular exercise (two times per week) to individuals who have been diagnosed with these conditions.[55]

Some preclinical evidence and emerging clinical evidence supports the use of exercise as an adjunct therapy for the treatment and prevention of drug addictions.[56][57][58][59]

Reviews of clinical evidence also support the use of exercise as an adjunct therapy for certain neurodegenerative disorders, particularly Alzheimer's disease and Parkinson's disease.[60][61] Regular exercise may be associated with a lower risk of developing neurodegenerative disorders.[62]

Depression

Part of this section is transcluded from Neurobiological effects of physical exercise. (edit | history)

Numerous systematic reviews and meta-analyses have indicated that exercise has a marked and persistent antidepressant effect in humans,[63][52][64][53][65] an effect believed to be mediated through enhanced BDNF signaling in the brain.[53] Several systematic reviews have analyzed the potential for physical exercise in the treatment of depressive disorders. The 2013 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.[65] Three subsequent 2014 systematic reviews that included the Cochrane review in their analysis concluded with similar findings: one indicated that physical exercise is effective as an adjunct treatment (i.e., treatments that are used together) with antidepressant medication;[53] the other two indicated that physical exercise has marked antidepressant effects and recommended the inclusion of physical activity as an adjunct treatment for mild–moderate depression and mental illness in general.[52][64] A 2016 meta-analysis concluded that physical exercise improves overall quality of life in individuals with depression relative to controls. One systematic review noted that yoga may be effective in alleviating symptoms of prenatal depression.[66] Another review asserted that evidence from clinical trials supports the efficacy of physical exercise as a treatment for depression over a 2–4 month period.[41] These benefits have also been noted in old age, with a review conducted in 2019 finding that exercise is an effective treatment for clinically diagnosed depression in older adults.[67]

A 2024 systematic review and network meta-analysis of 218 randomized controlled trials involving over 14,000 participants found that various forms of exercise, including walking or jogging, yoga, resistance training, and mixed aerobic activities, were associated with reductions in depressive symptoms. The review observed that the effects of exercise were comparable to those of psychotherapy and pharmacotherapy, with more intensive exercise yielding greater benefits. Resistance training was identified as particularly effective for younger individuals, while yoga appeared to be more beneficial for older adults. While confidence in the findings was limited by methodological concerns in the included studies, the review noted that exercise produced significant improvements in symptoms across a wide range of participants and treatment contexts.[63]

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),[68] β-endorphin (an endogenous opioid),[69] and phenethylamine (a trace amine and amphetamine analog).[70][71][72]

Sleep

Preliminary evidence from a 2012 review indicated that physical training for up to four months may increase sleep quality in adults over 40 years of age.[73] A 2010 review suggested that exercise generally improved sleep for most people, and may help with insomnia, but there is insufficient evidence to draw detailed conclusions about the relationship between exercise and sleep.[74] A 2018 systematic review and meta-analysis suggested that exercise can improve sleep quality in people with insomnia.[75]

Libido

One 2013 study found that exercising improved sexual arousal problems related to antidepressant use. [76]

Mechanism of effects

Skeletal muscle

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).[77][78] The stimulation of muscle protein synthesis by resistance training occurs via phosphorylation of the mechanistic target of rapamycin (mTOR) and subsequent activation of mTORC1, which leads to protein biosynthesis in cellular ribosomes via phosphorylation of mTORC1's immediate targets (the p70S6 kinase and the translation repressor protein 4EBP1).[77][79] The suppression of muscle protein breakdown following food consumption occurs primarily via increases in plasma insulin.[77][80][81] Similarly, increased muscle protein synthesis (via activation of mTORC1) and suppressed muscle protein breakdown (via insulin-independent mechanisms) has also been shown to occur following ingestion of β-hydroxy β-methylbutyric acid.[77][80][81][82]

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.[83] [77][84] These effects occur via an exercise-induced increase in the intracellular AMP:ATP ratio, thereby triggering the activation of AMP-activated protein kinase (AMPK) which subsequently phosphorylates peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), the master regulator of mitochondrial biogenesis.[77][84][85]

Signaling cascade diagram

Other peripheral organs

Summary of long-term adaptations to regular aerobic and anaerobic exercise. Aerobic exercise can cause several central cardiovascular adaptations, including an increase in stroke volume (SV)[87] and maximal aerobic capacity (VO2 max),[87][88] as well as a decrease in resting heart rate (RHR).[89][90][91] Long-term adaptations to resistance training, the most common form of anaerobic exercise, include muscular hypertrophy,[92][93] an increase in the physiological cross-sectional area (PCSA) of muscle(s), and an increase in neural drive,[94][95] both of which lead to increased muscular strength.[96] Neural adaptations begin more quickly and plateau prior to the hypertrophic response.[97][98]

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.[99] Exercise reduces levels of cortisol, which causes many health problems, both physical and mental.[100] Endurance exercise before meals lowers blood glucose more than the same exercise after meals.[101] There is evidence that vigorous exercise (90–95% of VO2 max) induces a greater degree of physiological cardiac hypertrophy than moderate exercise (40 to 70% of VO2 max), but it is unknown whether this has any effects on overall morbidity and/or mortality.[102] Both aerobic and anaerobic exercise work to increase the mechanical efficiency of the heart by increasing cardiac volume (aerobic exercise), or myocardial thickness (strength training). Ventricular hypertrophy, the thickening of the ventricular walls, is generally beneficial and healthy if it occurs in response to exercise.

Central nervous system

Further information: Neurobiological effects of physical exercise § Neuroplasticity

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.[38][103][104][105][106][107]

Public health measures

Multiple component community-wide campaigns are frequently used in an attempt to increase a population's level of physical activity. A 2015 Cochrane review, however, did not find evidence supporting a benefit.[108] The quality of the underlying evidence was also poor.[108] However, there is some evidence that school-based interventions can increase activity levels and fitness in children.[17] Another Cochrane review found some evidence that certain types of exercise programmes, such as those involving gait, balance, co-ordination and functional tasks, can improve balance in older adults.[109] Following progressive resistance training, older adults also respond with improved physical function.[110] Survey of brief interventions promoting physical activity found that they are cost-effective, although there are variations between studies.[111]

Environmental approaches appear promising: signs that encourage the use of stairs, as well as community campaigns, may increase exercise levels.[112] The city of Bogotá, Colombia, for example, blocks off 113 kilometers (70 mi) of roads on Sundays and holidays to make it easier for its citizens to get exercise. Such pedestrian zones are part of an effort to combat chronic diseases and to maintain a healthy BMI.[113][114]

To identify which public health strategies are effective, a Cochrane overview of reviews is in preparation.[115]

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.[116] There is some level of concern about additional exposure to air pollution when exercising outdoors, especially near traffic.[117]

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.[118]

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.[119] Implementing physical exercise in the school system and ensuring an environment in which children can reduce barriers to maintain a healthy lifestyle is essential.

The European Commission's Directorate General for Education and Culture (DG EAC) has dedicated programs and funds for Health Enhancing Physical Activity projects[120] within its Horizon 2020 and Erasmus+ program, as research showed that too many Europeans are not physically active enough. 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.

Running has become a popular form of exercise.
Main article: Exercise trends

Worldwide there has been a large shift towards less physically demanding work.[121] This has been accompanied by increasing use of mechanized transportation, a greater prevalence of labor saving technology in the home, and fewer active recreational pursuits.[121] Personal lifestyle changes however can correct the lack of physical exercise.

Research in 2015 indicates integrating mindfulness to physical exercise interventions increases exercise adherence, self-efficacy and also has positive effects both psychologically and physiologically.[122]

Social and cultural variation

Exercising looks different in every country, as do the motivations behind exercising.[3] In some countries, people exercise primarily indoors, and in others, people primarily exercise outdoors. 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. In Bogotá, Colombia, a 70-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.[123]

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.[124]

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.[125]

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.[126]

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.[3]

Nutrition and recovery

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.[127]

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.[128]

History

Roper's gymnasium, Philadelphia, circa 1831.

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."[129] Exercise was also seen to be valued later in history during the Early Middle Ages as a means of survival by the Germanic peoples of Northern Europe.[130]

More recently, exercise was regarded as a beneficial force in the 19th century. After 1860, Archibald MacLaren opened a gymnasium at the University of Oxford and instituted a training regimen for 12 military officials at the university.[131] This regimen was assimilated into the training of the British Army, which formed the Army Gymnastic Staff in 1860 and made sport an important part of military life.[132][133][134] Several mass exercise movements were started in the early twentieth century as well. The first and most significant of these in the UK was the Women's League of Health and Beauty, founded in 1930 by Mary Bagot Stack, that had 166,000 members in 1937.[135]

The link between physical health and exercise (or lack of it) was further established in 1949 and reported in 1953 by a team led by Jerry Morris.[136][137] Dr. 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.[137]

Other animals

Studies of animals indicate that physical activity may be more adaptable than changes in food intake to regulate energy balance.[138]

Mice having access to activity wheels engaged in voluntary exercise and increased their propensity to run as adults.[139] Artificial selection of mice exhibited significant heritability in voluntary exercise levels,[140] with "high-runner" breeds having enhanced aerobic capacity,[141] hippocampal neurogenesis,[142] and skeletal muscle morphology.[143]

The effects of exercise training appear to be heterogeneous across non-mammalian species. As examples, exercise training of salmon showed minor improvements of endurance,[144] and a forced swimming regimen of yellowtail amberjack and rainbow trout accelerated their growth rates and altered muscle morphology favorable for sustained swimming.[145][146] Crocodiles, alligators, and ducks showed elevated aerobic capacity following exercise training.[147][148][149] No effect of endurance training was found in most studies of lizards,[147][150] although one study did report a training effect.[151] In lizards, sprint training had no effect on maximal exercise capacity,[151] and muscular damage from over-training occurred following weeks of forced treadmill exercise.[150]

This rise in plasma HMB was accompanied by increases in MPS (PA: 0.046 ± 0.004%/h, CaHMB: 0.072 ± 0.004%/h, p < [0.001]) and suppressions in MPB (PA: 7.6 ± 1.2 μmol Phe per leg min−1, Ca-HMB: 5.2 ± 0.8 μmol Phe per leg min−1, p < 0.01). ... During the first 2.5 h period we gathered postabsorptive/fasted measurements, the volunteers then consumed 3.42 g of Ca-HMB (equivalent to 2.74 g of FA-HMB) ... It may seem difficult for one to reconcile that acute provision of CaHMB, in the absence of exogenous nutrition (i.e. EAA's) and following an overnight fast, is still able to elicit a robust, perhaps near maximal stimulation of MPS, i.e. raising the question as to where the additional AA's substrates required for supporting this MPS response are coming from. It would appear that the AA's to support this response are derived from endogenous intracellular/plasma pools and/or protein breakdown (which will increase in fasted periods). ... To conclude, a large single oral dose (~3 g) of Ca-HMB robustly (near maximally) stimulates skeletal muscle anabolism, in the absence of additional nutrient intake; the anabolic effects of Ca-HMB are equivalent to FA-HMB, despite purported differences in bioavailability (Fig. 4).

From a molecular perspective, elevated systemic levels of circulating growth factors such as vascular endothelial growth factor and insulin-like growth factor 1 (IGF-1) in blood elicited by increased exercise have been shown to mediate, in part, enhancements in neurogenesis (Trejo et al. 2001; Fabel et al. 2003).

Importantly, physical exercise can improve growth factor signalling directly or indirectly by reducing pro-inflammatory signalling [33]. Exercise-induced increases in brain monoamines (norepinephrine and serotonin) may also contribute to increased expression of hippocampal BDNF [194]. In addition, other growth factors—insulin-like growth factor-1 (IGF-1) and vascular endothelial growth factor—have been shown to play an important role in BDNF-induced effects on neuroplasticity [33,172,190,192], as well as exerting neuroprotective effects of their own [33,214,215], thereby contributing to the beneficial effects of exercise on brain health.

PMID 23720292. Abundant research in the last decade has shown that exercise is one of the strongest promoters of neurogenesis in the brain of adult rodents (97, 102) and humans (1,61), and this has introduced the possibility that proliferating neurons could contribute to the cognitive enhancement observed with exercise. In addition to BDNF, the actions of IGF-1 and vascular endothelial growth factor (VEGF) (54) are considered essential for the angiogenic and neurogenic effects of exercise in the brain. Although the action of exercise on brain angiogenesis has been known for many years (10), it is not until recently that neurovascular adaptations in the hippocampus have been associated with cognitive function (29). Exercise enhances the proliferation of brain endothelial cells throughout the brain (113), hippocampal IGF gene expression (47), and serum levels of both IGF (178) and VEGF (63). IGF-1 and VEGF, apparently produced in the periphery, support exercise induced neurogenesis and angiogenesis, as corroborated by blocking the effects of exercise using antibodies against IGF-1 (47) or VEGF (63).

PMC 3896879. PMID 24478719. Exercise-related improvements in brain function and structure may be conferred by the concurrent adaptations in vascular function and structure. Aerobic exercise increases the peripheral levels of growth factors (e.g., BDNF, IFG-1, and VEGF) which cross the blood-brain barrier (BBB) and stimulate neurogenesis and angiogenesis (Trejo et al., 2001; Lee et al., 2002; Fabel et al., 2003; Lopez-Lopez et al., 2004). Consistent with this, exercise-related enlargement of hippocampus was accompanied by increases in cerebral blood volume and capillary densities (Pereira et al., 2007). Enhanced cerebral perfusion may not only facilitate the delivery of energy substrates, but also lower the risk of vascular-related brain damages, including WMH and silent infarct (Tseng et al., 2013). Furthermore, regular aerobic exercise is associated with lower levels of Aβ deposition in individuals with APOE4 positive (Head et al., 2012), which may also reduce the risk of cerebral amyloid angiopathy and microbleeds (Poels et al., 2010).{{cite journal}}: CS1 maint: unflagged free DOI (link)
