What happens when you swim?

Summer is upon us, and that means swimming season is here as well. For some kids, this will be one of their main daily exercises because swimming every day will be good for the mind, body and soul. Swimming is one of the safest sports out of so many, but swimming for too long can turn out to be a bad thing. You'll see that there are many serious, competitive swimmers who typically spend more than an hour in the pool training, and some say it's not uncommon to spend two hours in the pool working out.

Why do so many people like to swim?

The moment you enter the water, you will feel your heart beating hard, your muscles will contract quickly, and your lungs will tighten up, which is the feeling of underwater exercise. Fortunately, this feeling does not last long, because after a few minutes, you have gotten over the initial discomfort and temperature change and entered a world that is almost as comfortable as walking normally.

The moment you learn to swim in the water, you will have a feeling as if you have conquered the pool, conquered the ocean, which is the most desirable.

Why swimming for too long is not good?

Swimming is a great exercise because it allows a person to perform a high intensity workout that puts not much stress on the back and legs. It's great for a full body workout and allows a person to burn as many calories in a short period of time as running for the same amount of time, achieving a quick fat burning effect. Often, people don't think of swimming as a sport that causes many injuries to occur. Too much swimming can lead to overexertion, which can easily cause injuries. Mainly shoulder pain and occasionally knee pain.

In recent years, the training of competitive swimmers has changed and they now train with many round trips. All this excessive swimming training leads to more overexertion injuries that may not be apparent at first, but are cumulative all the time. Shoulder pain is the main common problem swimmers encounter when swimming because their muscles are used repeatedly all the time while swimming, and this can lead to unequal muscle strength in the chest and back. And uneven strength of these muscles can lead to distorted swimming positions, which in turn can lead to shoulder pain or bring about a host of other pains. Common strokes that may cause shoulder pain are freestyle, backstroke and butterfly. Swimmers who participate in breaststroke are at the same risk of shoulder pain as other strokes, but will experience one more type of pain than they do - knee pain, which is caused by the kneecap moving and rubbing against other parts of the knee joint.

What happens to your body when you swim?

Do you know what happens to your body positions when you are swimming?


Swimming is recognized as one of the great aerobic exercises. Aerobic exercise expands the heart and increases blood flow throughout the body, and swimming will speed up the flow of blood to the body


When you swim for a few minutes, your body breathes aerobically, which causes your heart rate to increase. While your heart is responsible for circulating oxygenated blood, your increased heart rate will effectively deliver oxygen to your muscles


Whether you're swimming or doing anything else to move, that's when your body generates heat. Then your blood vessels expand, bringing heat to your skin, which is then released. That's why your skin feels warm when you work out, your body is releasing all that inner heat! This causes your body and face to turn red!


During swimming or swimming strength training, you will experience micro-tears in your muscles. This takes about 1-2 days for your body to recover and rebuild the muscles.


When swimming, your breathing rhythm is different from your normal breathing rhythm and may be more difficult, requiring your lungs to absorb more oxygen.

Swimming increases your lung capacity. Over time, as you become healthier, your lung capacity will increase, so your lungs will become more efficient at breathing.


Your brain will mark "like swimming". The extra blood and oxygen to your body helps you become more alert, awake and focused.

What to pay attention to swimming

Warm up: Make sure the swimmer is warmed up properly. The type of warm-up is also important. Make sure the warm-up is an active, not a passive stretch. Swimmers have many traditional stretches to warm up. The goal of these warm-ups is to maintain joint stability in the shoulder area. It is important to warm up and actively stretch the muscles themselves, not just the shoulder joint.

Hydration: Finally, be sure to drink plenty of water. In addition to sweating during exercise, being in the pool can dehydrate your body.

Rest:When you swim a certain time, you must rest, because your body has entered the warning period, if you do not have sufficient rest and then continue, your body will be "load" state, this time will be the most vulnerable to injury.
