Popis:	A mathematical model is described that predicts the body kinematics of tadpoles swimming in a straight line at constant velocity. The model is a forced beam with a variable moment of inertia and cross-sectional area. The beam is free at both ends and forced cyclically at the position that corresponds to the base of the tail in a real animal. This forcing regime simulates the real contraction of locomotor muscles. Finite-dimensional numerical techniques were used to approximate the solution. The lowest predicted fundamental frequency of vibration should be the resonant frequency of vibration of the tadpole. The predicted resonant frequency and the observed swimming frequencies were in good agreement.
