The Role of Springs in Trampoline Bounce

The trampoline is nothing but repetitive jumping in the air. Spring plays a vital role to create bounce there due to continuous contraction and distention of the springs.

The bouncing power of the trampoline is largely dependent on the resilience of the springs. Springs contribute to the trampoline bouncing cycle based on two basic physics laws.

  1. Newton’s Third Law of Motion: “For every action, there is an equal and opposite reaction”. This happens on the trampoline. As you jump on the trampoline, you create a downward force. And springs apply the opposite force to you hence you bounce back in the upper direction.
  2. Hooke’s Law of Elasticity: “The force required to extend a spring is proportional to the length of the extension”. According to the theory, if a heavy person jumps on the trampoline, he/she can jump higher than a slim person. This happens as a heavy person creates more stretching on sprigs since he/she bounces higher in the air.

Types of Trampoline Springs

Trampoline springs are available in different types such as-

Regular Steel Springs

Every one of us is familiarized with coiled springs with two end hooks these are the regular springs in the trampoline. This type of spring is widely used in rebounders, backyard trampolines, and trampoline parks.

It is cheaper and available at any local store. These springs have two hooks that attach the frame and mat together.

They don’t last long and may form rust soon. Also, they need some extra care to reduce squeaking. And there are high chances of injury if fingers or feet are caught in it.

Some coiled springs are made for recreational jumping. Another kind of trampoline spring is large and thick that is used in the competitive trampoline for heavy-duty performance and higher jumping.

Bungee Cords

This is an elastic strap spring that stretches with bounce. It’s good for joint-friendly exercises. Most kid’s mini-trampolines and adult rebounders use these springs. But you may see them in some round trampolines.

Heavy-duty trampoline springs come with a proper galvanized coating that prevents rusting and damage to the springs. The coating hinders sun, rain, snow, or ice to interact with springs, thus the springs last longer without any decay.

Both the coil and hook of the springs should be sturdy. And be sure the wire diameter of the spring is good enough like 3mm. Some springs are double tapered that are designed for heavy-duty performance.

Also, check the number of coils in the springs. If there are lots of coils, this will stretch more and provide high bouncing. Some spring hook ends nowadays have rubber caps for extra safety.
