Abstract	This note presents measurements of the muon reconstruction and isolation efficiencies based on an analysis of Z->μ+μ- decays in 40 pb-1 of sqrt(s)=7 TeV proton-proton collision data recorded with the ATLAS detector in 2010. The data entering the analysis were reprocessed with an optimized ATLAS reconstruction software and improved detector calibration and alignment constants.
