30 Mar Swimming fins – Skates of swimmers
Any career is very elaborate. The fins – a “toy” for swimmers practice – is a pretty simple visual device, but to understand it deeply, especially in terms of its usage, is not a simple matter.
In this article, I would like to share with readers the important points of the fins so that you can choose for yourself a pair of fins that you like and suitable for your training purpose, to avoid “money loss” for a relatively expensive” toy “compared to a swimming cap!
Understand the difference between swimming fins and SCUBA fins
First, you need to differentiate between swimming fins and dive fins or SCUBA fins. There are many differences between the two but the defining factor is that the dive propeller has a longer nose and is designed for a slow, wide foot movement, used to overcome diving gear resistance (divers The swimmers usually do not use their arms to swim), while the swimmers have a much shorter nose to help build the swimmer’s muscles by increasing the resistance to the leg movements, as well as many other benefits that are discussed below.
Next, you need to understand the benefits brought about by the fins. In general, most people feel that bringing swimming fins in will swim faster, but exercising with swimming fins offers more than just a quick swim.
And let us reveal a secret: The biggest benefit of swimming fins is that fins can help us swim better without a propeller! What this means: the fins are just a tool to aid us in our exercise, not something we overuse or depend on. It is like a remedy, using the right amount and getting the right amount is good; Using the wrong amount, not in the right amount is… dangerous!
What can Swimming fins help us?
Swimming fins is not only a toy for swimmers but it is also really useful for us when swimming
Improve ankle joint flexibility
The importance of ankle flexibility to swimmers is undisputed and is one of the most important factors in effective pacing. Many triathlons and new swimmers experience poor leg beats because they don’t have ankle flexibility.
The good foot beat technique involves maximally extending your ankle joint so that your toes are in line with the shin (knee to toe is a straight line). This increases the cross-section of the foot impacting the water and increases repulsion. If you don’t have ankle joint flexibility, you can just kick the water downwards, not later.
The presser foot will place your foot in a position where your ankle joint is forced to straighten, which will help improve overall flexibility in your foot.
Improved foot beat technique (makes kicking better)
A fairly common mistake made by most recreational swimmers is improper kicking (in stride and butterfly swimming) or down kick (in backstroke). These movements are quite strange for natural human leg movements and make people feel awkward about them. The correct up kick should be the movement that comes from the hip to lift the leg almost straight up to the water, not a knee bend to kick the foot up.
Again: the correct leg flap is not a knee stretch to “knock” the foot up and down, but “hit down with the front of the knee and hit with the back of the knee”. That is the ultimate move of foot movements!
When the fins is worn, the added surface area of the presser foot helps you handle this up-kick technique comfortably because you cannot bend the knee to kick the presser. In other words, the fins will teach swimmers to beat their feet from the hips, not the knees, and help LEFT your leg movements.
If you really want to improve your kick-ups, try adding leg flaps in the upright position, especially with butterfly kicks.
Improve body posture – improve swimming techniques
Many swimmers have a really strong vacuum movement, so the body sagged, creating a lot of resistance when swimming and affecting the techniques of other parts.
Many swimming fins float on the surface of the water. That means when you swim with them, the fins will keep your feet higher in the water, encouraging a higher overall body posture. When your body floats high in the water and you reach a certain speed through the aid of the propeller, your hand fan frequency can decrease, and that allows you more time to exercise on technical elements like the swinging of the air or the hand’s underwater fan motion. I myself often use the fins when I swim backward because my buoyancy is not very good, when I put the fins in, I can swim back more gently and accurately.
To get a proper cardio exercise, you need to use the majority of your total muscle mass over a 20-30 minute workout period. More than 60% of your total body mass is located in the legs, so any proper cardio exercise involves a lot of leg activity. When running, this is easy. However, when you swim, your arms are used a lot to push the body forward and legs are often neglected. Human feet are not designed for swimming. They have a very small surface area and are not good for thrust when swimming.
So how can we get our feet to work harder and still have enough energy for a 20-30 minute workout to have a good cardiovascular impact? Thanks to swimming fins.
Wearing fins increases the resistance of your leg movements by adding more surface area to your feet. The more resistance, the heavier the exercise. And the more active your feet are, the harder your heart will work. And it is this high heart rate that, like any other muscle training, makes your heart stronger.
