Harvard medical school published a study which looked at over 40,000 men, aged 20-90 who were either runners, walkers, swimmers, and physically in active people. With an average length of 13 years of observation and in that time
- 2% of swimmers passed away
- 8% of runners passed away
- 9% of walkers passed away
- 11% of physically inactive people passed away
This study showed that swimmers are much healthier later on in life than the rest of the population and for women swimming just 30 mins a day can decrease coronary heart disease by 30 to 40 percent.
It also helps to increase HDL aka good Colestrol. Some studies have also shown that aerobic excercise can keep the cells in the lining of your arteries more flexible and healthier. Hence there is no question that swimming is an awesome form of fitness.
Body during swimming
What do you actually feel when you go into the water? Here are some main elements of the human body that gets impacted during swimming.
According to the America Heart Association, swimming is considered as Aerobic activity. Aerobic excercise enlarges the heart and it increases the blood flow through the entire boby. Because swimming is an excercise, the blood has to pump all the molecules into the body.
Since so much of blood has to be pumped into the body, that ties into how it impacts your heart because we know that after 2 mins your body goes into aerobic respiratory because your heart has to pump all the oxygenated blood through the body. So as you swim, your heart is circulating the blood which help your body to perform and achieve the required goals.
You must have seen that the skin color changes of swimmers. For example, some swimmers face turns red when the swim, that happens because your blood vessels are dilating and the brings the heat to the surface into the skin then some people turn red, as a result your skin is showing the effort that you’re putting in the water.
There’s a reason why swimmers are considered to have best body and physiques in the world compared to any athlete, because swimming engages every single muscles in the water when it comes to your core stability, your upper body, your biceps, your hamstrings, your calves, everything is engaged when you swim.
When you’re swimming, you are micro tearing your muscles while swinging it. And the muscles requires 24-48 hrs to recover those muscles. That’s when sometimes you might feel sore.
Swimming can actually help increase your lungs volume because in swimming different than other sports, you can’t actually breath whenever you want. It’s not like running when you have full access to oxygen.
In swimming you’re engaging your muscles and you’re not allowed to breathe necessarily at the time when your body might want it. So because you have to get used to this, you actually increase your Vo to max (maximum amount of oxygen body is able to use). So basically you are making your lungs more efficient at functioning.
The Brain loves swimming, because of all the extra blood flow moving through these endorphins that makes you more awake, alert and focus.
But this could happen in any type of sport but swimming is something really special because you’re sort of in your own world where the medium is 800 times more dense than air, which makes you feel free and relaxed.
Hence, from physical health to mental health, swimming is an incredible benefit human body and after reading this you must be thinking of trying swimming.
