Parkinson's disease is a chronic neurodegenerative disorder that affects the central nervous system and is characterized by motor symptoms such as tremors, muscle rigidity, slowness of movement and balance problems. As the disease progresses, it can also cause other non-motor symptoms such as depression, sleep disorders, and cognitive difficulties. Although the exact cause of Parkinson's disease remains unknown, much research has been done on risk factors and prevention strategies. One of the aspects that has sparked interest in the scientific community is the role that physical exercise can play in protecting against this disease.
Exercise as protective factor
Physical exercise has established itself as a fundamental pillar in the promotion of health and the prevention of numerous chronic diseases. Various studies have shown the benefits of exercise on physical and mental health, including improving cardiovascular function, reducing the risk of obesity and preventing diseases such as type 2 diabetes. In the case of Parkinson's disease, Evidence suggests that regular exercise could play an important role in protecting against this disease.
Epidemiological studies
The relationship between physical exercise and Parkinson's disease has been studied in various epidemiological works that have analyzed large populations over time. One of the first studies that pointed to a possible association between exercise and a lower risk of developing Parkinson's was published in 2009 in the journal Neurology. In this study, it was observed that people who engaged in intense exercise had a significantly lower risk of developing the disease compared to those who had a sedentary lifestyle.
These findings provided the starting point for a series of subsequent investigations that confirmed and expanded the relationship between physical exercise and protection against Parkinson's disease. In a meta-analysis published in 2014 in the journal JAMA Neurology, it was concluded that regular physical activity was associated with a lower risk of developing Parkinson's disease, regardless of the intensity of the exercise performed.
Mechanisms Biological
To understand how exercise can influence protection against Parkinson's disease, it is necessary to analyze the possible biological mechanisms involved. It has been proposed that regular physical exercise could have beneficial effects at the molecular and cellular level that could help counteract the neurodegenerative processes associated with the disease.
One of the proposed mechanisms is the ability of exercise to promote synaptic plasticity, that is, the brain's ability to change and adapt in response to external stimuli. Exercise has been shown to stimulate the release of neurotrophic factors, such as brain-derived neurotrophic factor (BDNF), which promote the growth and survival of neurons. These changes at the synaptic level could contribute to protecting the brain areas affected in Parkinson's disease, such as the substantia nigra and the striatum.
In addition, physical exercise has been shown to have anti-inflammatory and antioxidant effects on the body, reducing chronic inflammation and oxidative stress, processes known to be involved in neurodegeneration associated with Parkinson's disease. Likewise, exercise promotes neurogenesis, that is, the formation of new neurons in brain regions key to motor control and cognitive function, which could help compensate for the loss of dopaminergic neurons observed in Parkinson's.
Types of exercise and recommendations
The type of physical exercise performed can also influence the protective potential against Parkinson's disease. It has been observed that both aerobic exercise, which involves the rhythmic movement of large muscle groups, and strength exercise, which involves resistance against an external load, can provide benefits in preventing the disease. Additionally, activities that involve coordination, balance and flexibility, such as yoga or tai chi, may be especially beneficial for improving motor function and preventing falls in people with Parkinson's.
Current recommendations suggest that it be performed a minimum of 150 minutes of moderate-intensity aerobic exercise per week, spread over several days, along with strength exercises that involve all major muscle groups at least two days per week. In addition, it is recommended to include activities that promote flexibility and joint mobility to maintain functionality in daily life.
Adherence to exercise
Despite the obvious benefits of exercise in the protection against Parkinson's disease, one of the most important challenges is to ensure that people maintain a regular routine of physical activity over time. Adherence to exercise can be influenced by various factors, such as the perception of the effectiveness of exercise to prevent disease, the availability of resources and adequate spaces for practicing sports, and personal motivation.
It is important. that people know the specific benefits that exercise can provide in the prevention of Parkinson's and that they have the support of health professionals and specialized trainers to establish an exercise plan adapted to their needs and preferences. Furthermore, the inclusion of community exercise programs and the support of groups of people with similar interests can be effective strategies to promote long-term exercise adherence.
Conclusions
In Summary, regular physical exercise appears to play a protective role against Parkinson's disease, reducing the risk of developing this neurodegenerative disease. The biological mechanisms involved include the promotion of synaptic plasticity, anti-inflammatory and antioxidant effects, and the stimulation of neurogenesis in the brain. Different types of exercise, such as aerobic exercise, strength training, and balance and flexibility activities, can provide benefits for both motor and cognitive function in people at risk of developing Parkinson's.
It is essential to promote exercise. raise awareness about the importance of physical exercise in the prevention of Parkinson's disease and provide people with the tools and support necessary to maintain a regular physical activity routine throughout their lives. The combination of an active lifestyle, a healthy diet and the control of other risk factors can significantly contribute to reducing the incidence of this disease and improving the quality of life of those who suffer from it.
