We use the degree formula for connective Ktheory to study rational contractions of algebraic varieties As an application we obtain a condition of rational incompressibility of algebraic varieties and a version of the index reduction formula Examples include complete intersection rationally connected varieties twisted forms of abelian varieties and CalabiYau varieties
