**8. Conclusions**

Properly planned strength training programs incorporating SME, which the IML supports, can improve maximal strength. The use of the IML as a SME training device for athletes who do not have an advanced level of strength is not advised. Athletes need to have the technical abilities and adequate strength to manage supramaximal loading. Athletes without high strength levels can utilize the device for other methods of training.
