Omelianchik continued to compete for the Soviet team after the World Championships, placing third in the all-around at the 1986 Goodwill Games and third all around at the World Cup in Beijing. She also won the balance beam title and placed second on uneven bars and vault and third on floor exercise. The following year at the World Championships the Soviet team lost the title to a dominant team from Romania. Omelianchik debuted her new vault which introduced the half on technique in the roundoff family of vaults. She also showcased a new floor routine to "Ballet Russe" and a new triple full to a tuck front rebound, but suffered an uncharacteristic fall in the team competition. She placed fifth all around and failed to compete in any event finals. She qualified for the vault final but was withdrawn and Svetlana Baitova competed in her place.
