Observed period changes in SX Phe and Population I high amplitude delta Set stars have been collected and compared with those expected from different stellar evolutionary tracks inside the Lower Instability Strip including modern evolution models using the new opacities by Rogers & Iglesias (1992) and Kurucz (1991).
