Abstract / Description:LEP and SLC provide accurate data on the process (e^+e^- -> f bar f) at the Z resonance. The GigaZ option at a future linear e^+e^- collider (ILC) will further improve these measurements. As a consequence, theory predictions with sufficiently smaller errors are necessary in order to fully exploit the experimental accuracies and to derive indirect bounds on the scales of new physics. Here we review the currently most accurate predictions of the Z pole observables (e.g. sin^2 theta_eff, Gamma_Z, sigma^0_had) in the context of the Minimal Supersymmetric Standard Model (MSSM). These predictions contain the complete one-loop results including the full complex phase dependence, all available MSSM two-loop corrections, as well as all relevant Standard Model contributions.
