In Lopez et al v. Skate Key, Inc. et al. (174 AD2d 534 [1st Dept 1991]), it was held that participants in sporting events were deemed as a matter of law to have assumed the known risks associated with the particular sport and that collisions between skaters were a common occurrence, and found that there was insufficient evidence in the record to demonstrate the existence of a dangerous condition for a sufficient period of time to have put the skating rink on notice and that the collision was a result of the sudden and abrupt action of another skater which was a risk assumed by the skater as a matter of law.
