"Our athlete David Shamey set a Russian and world record in pushing out a ball dumbbell weighing 147.5 kilograms [325.2 pounds].
The record is dedicated to the 81st anniversary of the Great Victory," Paller said.
The previous record in this discipline was 146 kilograms and belonged to Polish athlete Mateusz Kieliszkowski, the official said.
In addition, Ramazanov set a Russian and world record in the absolute weight category among athletes over the age of 40 by lifting and holding a 120-kilogram giant dumbbell overhead with one hand, Paller said.
Previously, the heaviest giant dumbbell lifted overhead in this category weighed only 100 kilograms, he said.
The records have been established and officially registered, Paller said.
The achievements were recorded in the Russian city of Tula.
