At present, almost all treadmills on the market are flat, and such treadmills lack elasticity. When a person falls on the treadmill during running, it will form a huge recoil and increase the pressure on the knee, which will easily cause knee joint injury. In order to solve this problem, treadmill manufacturers have designed many different forms of shock absorption functions under the running board, but they still treat the symptoms rather than the root cause. Many people who often use treadmills still cause knee discomfort and pain. This is also the reason why treadmills are sold more and more, and there are more and more cases of knee joint injury.
Arched treadmill is a new generation treadmill, and the running board is arched and elastic. The arched running board itself has a strong cushioning function, and the huge impulse generated at the moment when the runner's foot falls on the running board will be released to both ends of the running board to avoid knee injury to the maximum extent. People who often use the flat treadmill to cause knee discomfort and then change the arch treadmill say this: the arch treadmill is very elastic, and it feels like running on a plastic track when running, which is very comfortable.
