An analysis was carried out of the secular period variation of four WU
Ma type stars (AW UMa, AP Leo, AG Vir and AH Vir) using some newly
determined times of minima as well as others reported in the literature.
It was found that two stars show period increases, one a period decrease
and the remaining shows no variation in period.
