We present a combined next-to-leading order (NLO) QCD analysis to data on both inclusive and semi-inclusive polarized deep inelastic scattering asymmetries. Performing NLO QCD global fits with different sets of observables, we evaluate the impact of the very recent semi-inclusive results presented by the Spin Muon Collaboration in the extraction of NLO polarized parton distributions, and in the estimate of polarized sum rules.
