Swimming has incredible effects

Swimming is really good for the brain, although scientists have not yet figured out why it is more effective than other aerobic activities.

It’s no secret that aerobic exercise can help prevent aging and some health problems with lifeguard training. But a recent study showed that swimming, in particular, is a lifesaver for our brain health. Swimming regularly, in fact, improves memory, cognitive functions, immune response, and mood, but would also help repair the damage resulting from stress and create new neural connections within the brain.

Until the 1960s, scientists believed that the number of neurons and synaptic connections in the human brain was finite and that once damaged, brain cells could no longer be replaced. In recent years, however, it has been discovered that fortunately neurons can also be born and develop in the adult brains of humans and other animals – in a process called neurogenesis.

A study conducted a few years ago showed how aerobic exercise can contribute to the neurogenesis process, playing a key role in repairing damage to neurons and their connections in mammals and fish. The key to this ‘repairing’ process is in the increase of a protein called BDNF ( Brain-Derived Neurotrophic Factor ): the neural plasticity stimulated by this protein, or the ability of the brain to change and evolve, greatly improves cognitive functions such as memory. and learning.

Swimming the aerobic

But why is swimming the aerobic activity that improves our brain capacity more than others? Researchers have not yet been able to find an explanation for this mystery. Swimming certainly has positive effects on our circulatory system: involving practically all the muscles of the body, the activity carried out by the heart while swimming is massive, as is the flow of blood throughout the body with lifeguard training. This leads to the formation of new blood vessels (a process called angiogenesis ) and the release of endorphins, the hormones that cushion pain perception and improve mood.

Furthermore, research has shown that swimming in old age has important cognitive benefits: analyzing the impact of swimming activity on the mental acuity of older people, the researchers concluded that swimmers improved their mental speed. and attention to those who have not dedicated themselves to the sport.

Benefits of swimming in younger

Another study instead focused on the benefits of swimming in younger minds with lifeguard training: the researchers tested the memory skills of children between the ages of 6 and 12, struggling with learning difficult words, after having carried out three types of activities – coloring (a relaxing activity), swimming (an aerobic activity), and doing cross-fit exercises (an anaerobic activity). It turned out that children who had swum after learning the words remembered them much better than those who had done any other type of activity – demonstrating the importance of swimming even for a young and growing brain.

Benefits of swimming and all the muscles that work in various styles

What are the benefits of swimming and why is it considered a complete sport? What are the muscles that work stroke after stroke in different styles?

Swimming is a physical activity that is not only pleasant but also useful, in fact, swimming is considered one of the most complete exercises ever since it involves most of the muscles.

If on the one hand, it helps to tone the body with lifeguard training, on the other it allows you to burn many calories and also promotes relaxation. But the benefits don’t stop there.

The benefits of swimming

We said that swimming is excellent for toning the body and for strengthening the various muscles, especially those of the back, which is why it is recommended for those suffering from hip problems, hernias, and low back pain. It is also great for burning calories by increasing lean mass at the expense of fat mass, and for making joints more flexible as we use most of the muscles while swimming.

Not to mention that thanks to the halving of the perception of weight. Due to water, even people who are not particularly trained can try. Their hand at this sport without getting too tired.

Another benefit concerns the spine which is strengthened by constant practice. And it is also a panacea for those suffering from high cholesterol. It helps to keep it under control, regulates blood sugar levels, and reduces blood pressure.

According to an article published on the CDC. Two and a half hours a week of aerobic physical activity such as swimming. Would be enough to reduce the risk of chronic diseases. It has in fact also proved useful for those suffering from diabetes and heart disease. And as for the mind, swimming helps release positive endorphins for a good mood, improves concentration and motivation.

Ditto for children, swimming helps them strengthen muscles, strengthen bones, improve cognition and concentration, and apparently self-esteem as well.

The muscles that work in the various styles

Swimming is one of the physical activities that involve more muscles but each style works more on some of them. Let’s find out one by one.

The freestyle involves the alternating movement of the arms and the use of the lower limbs. The muscle groups involved are the superficial and deep abdominals. The lumbar muscles, the triceps, the great dorsal contribute to the propulsion movement. The anterior-posterior deltoid, the buttocks.

The Back provides, like the Freestyle, an alternating movement of the arms and a propulsive movement of the legs. In this case, the muscles most involved are the great dorsal, the trapezius, the great teres. The great pectoral, the infraspinatus, the teres minor. The biceps, the brachialis, the brachioradialis, the pronator teres, the rhomboid.
In the Frog, the arms move forward and spread out while the legs make a pushing and gathering movement. In this case, the muscles most involved are the medial ligaments of the knee. The front part of the leg, the posterior tendons, the peroneus, the deltoid, the quadriceps.

Finally, the Dolphin, also called butterfly style, consists in moving the body like a wave. Moving the arms in unison with rotations that advance and propel the legs. The muscles most used are the subscapular ones. And again the pectorals, grand rotunda, metacarpophalangeal joints. Palmar interosseous, fifth digital opponent, rhomboid, biceps, brachial, brachioradialis, pronator round. Long palmar, wrist, adductor of the thumb, an opponent of the thumb, legs.
