Swimming is a strange sport in which your stamina determines only 50 percent of your swimming speed, the other 50 percent is technical. If you notice, the world’s top swimmers are not completely identical.
And one of the technical differences we most often see is the position of our fingers while swimming. Normally, we see many people close their hands when swimming, but there are also many people who just partially closed. So how is the right movement?
Without much thought, we can say no with cambered arms and arms spread immediately. The cambered hands make the hand section smaller, resulting in less efficient water fans. The open arms will make the water pass through the fingers and will not fan the water effectively.
So we have 2 options for tight dual hands and half-closed hands. The fingers are leaning against each other to create a solid, seamless hand. They are like a fan table, it is more resistant to the repulsion of water when pulling water more easily.
You will have to tuck your hands often to squeeze your fingers together, which is a waste of energy. However, this is the optimal choice for newbies because it is simple, easy to do and easy to correct.
Hands half-closed with fingers only a small distance apart corresponding to the distance when your hands are relaxed. This hand style has the most important outstanding feature.
This maximizes the cross section of the hand without allowing water to get through the fingers. With a cross section you pull the most volume of water, like you wear a pair of large fan tables.
This is something people rarely think about. We still often think that if the water is partially closed, it will pass through the fingers, thereby swimming ineffective. You can try both when you understand the strengths and weaknesses of each type and your own abilities. Wish you a good swim.
