  Motivated by desire to shed light on the strong coupling behaviour of
anomalous dimensions of "short" gauge theory operators we consider the famous
example of folded spinning string in AdS_5 in the limit of small semiclassical
spin parameter \S = S/sqrt[lambda]. In this limit the string becomes short and
is moving in a near-flat central region of AdS_5. Its energy scales with spin
as E = sqrt[2 S] [ a_0 + a_1 S + a_2 S^2 + ...]. We explicitly compute the
leading 1-loop quantum AdS_5 x S^5 superstring corrections to the short-string
limit coefficients a_0 and a_1 and show, in particular, that a_1 receives a
contribution containing \zeta(3).
