Intensive swimmers need to understand the mechanisms, advantages and disadvantages of each way to make the most of the trip. We often see top stride swimmers or triathletes swimming open water with very different types of aerial returns. But either way, everyone swims fast.
Every type of recover has advantages and disadvantages. You will often see groups of swimmers short in the pool or triathletes using a higher straight arm style than those who choose to bend.
However, players can still use both types of recovery when swimming long distances. But often the retractable arm is commonly used at medium and long distances.
If straight arms consume more energy, why choose? That’s because swimming is a combined movement. The combined movement is made up of the movement of several body parts that have not produced any repulsion by itself.
But when combined with thrust, it turns into accelerations that increase the force of swimming. The reason is that with this style of swimming, swimmers often enter the water and let their hands slide before entering the power phase.
Nowadays modern swimmers have a lot of hybrid stride swimmers and they are also getting the benefit of 1 hand 1 hand recover. We should also consider the biomechanical factors involved when doing this type of recovery.
To straighten your arms, the torso must rotate slightly back enough to allow the shoulder joint to rotate during that movement. But not everyone can do this easily, and many athletes do not have a core strong enough to repeat body rotation.
When the hand is recovered above the water, the arm connects it to the body via the shoulder point, and for analysis, we can view it as it is in the same system. This also means that more vigorous activity is required when straight-handed. And we can easily experiment when shooting two types of hands on land.
