We investigate a mechanism of baryon mass genesis by exploiting a pulsating soliton on a hypersphere. To do this, we construct the first class Hamiltonian to quantize the hypersphere soliton, and evaluate the axial coupling constant gA. In particular, we find that the predicted value for gA is in good agreement with its corresponding experimental data. The predictions for baryon masses in the Dirac quantization are improved comparing with those in the canonical one. Next we evaluate the intrinsic frequencies of the pulsating modes to relate them with the baryon masses. Moreover we find that the intrinsic pulsating frequency of more massive particle is greater than that of the less massive one. Explicitly, we evaluate the intrinsic frequencies ωN and ω∆ of the nucleon and delta hyperon, respectively, to yield the identity ω∆ = 2ωN .
