We evaluate the enhancement factor of the effective mass, m \* /m, for polarons in a crystal composed of either the E e or the T t Jahn-Teller (JT) centers in the strong-coupling region. A much larger m \* /m is found in the T t JT polarons than that in the E e ones. This difference originates from
