Why is it that transition state enthalpies tend to be positive?

The transition state enthalpy is very similar to the activation energy. Because enthalpy describes heat transferred and heat is a transfer of energy. According to certain collision theories, the transition state enthalpy is in fact the exact SAME thing as activation energy.
