Competition results in gymnastic vaults depend in great measure on testing and tuning of the springboard???s mechanical parameters, especially the stiffness. There are four empirical tests of the gymnastic springboard; one of them is a static test, and the three others are dynamics tests. The accuracy of the well-known springboard model (with an error up to 70 %) is not acceptable in the testing. Therefore, the purpose of this research is to develop a model for the imitation of springboard stiffness testing that should have appropriate accuracy in engineering calcula-tions. Gymnova (2012) was studied as popular equipment for gymnastic springboard vaulting. In the main load range area (1,500 ?? 3,500 N), according to the experimental testing, displace-ments of the upper board obey the linear function approximately on 99.7 %. The corresponding error of the elastic solid-body model developed in this research is 3.6 %, contrary to the multibody model created by Lehmann et al., where it is about 45.9 %, i.e., 13 times over. The mechanical and mathematical model of gymnastic springboard that was developed in this re-search, created on the basis of an overhanging beam with a console protrusion, has quite acceptable accuracy and can be recommended for engineering calculations, virtual testing, and simulation of the technique performing gymnastic vaults.
