We report constraints on antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% muon antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4{+-}11.7(stat){sub -8.9}{sup +10.2}(syst) events under the assumption |{Delta}m{sup 2}|=2.32x10{sup -3} eV{sup 2}, sin{sup 2}(2{theta})=1.0. Assuming no oscillations occur at the Near Detector baseline, a fit to the two-flavor oscillation approximation constrains |{Delta}m{sup 2}|<3.37x10{sup -3} eV{sup 2} at the 90% confidence level with sin{sup 2}(2{theta})=1.0.
