A kidney belt does more than just protect the organs in your lower back, the lumbosacral spine (the lowest part of your back) is subject to repeated bouncing and jerking motions during every single lap of a motocross track.
The results of excessive exposure to these types of forces can result in:
- Nerve compression
- Irritation and inflammation
- Sharp pain
- Radiating pain to your glutes, hips, thigh and leg muscles
Any time you are riding in pain is going to affect your performance, if you are racing it could mean the difference in winning or losing and if you are a recreational rider the early onset of pain and fatigue can put a downer on your ride day. Whatever level you are at, lower back pain is something nobody wants to encounter!
