The computation of {rho}={ital m}{sub {ital W}}{sup 2}/{ital m}{sub {ital Z}}{sup 2}cos{sup 2}{theta}{sub {ital W}} for two different models is performed. The heavy-Higgs-boson and the techni-{rho} contributions are considered in next-to-leading order. The two results are found opposite in sign, although too small to be detected experimentally at present.
