A small study found that the human body is very good at adapting to various surface softness, and will instinctively adjust the leg stiffness (Leg Stiffness) to adapt to changes in surface elasticity. Runners with knee problems generally prefer softer surfaces, although there is no definitive evidence that any of the outdoor surfaces, such as asphalt, concrete, turf, and gravel, are better at preventing injuries or reducing impacts.
The “softness” of the ground can also be replaced by other risk factors. For example, although the surface is soft, there are many uneven surfaces such as potholes and tree roots, which may increase the risk of injury.
At this point, treadmills offer a solution, with a soft, flat, and complete surface, and in a controlled training environment, especially when running on your own personal treadmill, you’ll get a consistent environment every time. Although there is not enough scientific evidence to prove that treadmills can reduce knee injuries, adding up the above conditions, treadmills may indeed be of great help to runners with knee problems.
Treadmill selection advice for those with knee problems
Of course, not every treadmill is the same, even if you can control it. When you want to buy a treadmill for home training due to the epidemic, busy work, and other reasons, the following are the functions that you must know before purchasing if you have knee problems.
1. Crawler running belt
Many runners have knee problems because of the lack of recruiting of the surrounding muscles and the weakness of the back section, while the crawler belt has fewer springs, which naturally forces you to recruit more muscles in the rear of the body and muscles in the lower body, and when there are more muscles in the lower body to help you run, which not only improves your running style, inspires a gentler landing, but also further reduces stress on your joints.
2. Curved manual treadmill
The curved unpowered treadmill was developed by Olympic track and field winner Alex Astilean to improve exercise efficiency and effectively reduce training injuries. The treadmill is environmentally friendly and non-electromechanical. It controls the speed through the force of the body. That is to say, the machine is powered by yourself, not when you step on it and run with the belt, which can better simulate the outdoor environment. Running without electric propulsion. At the same time, it greatly increases the use of muscle groups in the rear of the body and recruits more glutes, hamstrings, and calves than traditional treadmills.
In addition, the curved design of the belt can also aid those in the early stages of recovery after an injury, helping to restore a natural gait, making the heel used to touch the ground stronger when walking, and restoring natural heel-toe mechanics as the pace picks up.
The advantage of the curved treadmill is that it is self-propelled, which is more efficient than traditional treadmills. The curvilinear nature encourages proper running mechanics by shifting focus to the back chain of the legs (aka your hamstrings and glutes), which has less impact on the joints so you can move stronger and faster, without a high risk of injury. There are no downsides.
