To elucidate the strain effects of dynamic cyclic loading on the skeletal muscle-tendon unit, the muscle-tendon unit of New Zealand white rabbits were tested with different strains and strain rates under ketamine general anaesthesia. The results indicated that the dynamic responses of muscular tissues were both strain and strain-rate dependent with appreciably non-linear characteristic. The muscle-tendon unit behaved viscoelastically below 12% strain; but when stretching more than 16% strain it began to behave plastically. The loading energies and unloading energy are more dependent on strain than on strain-rate.
