As of May 2015, the fastest slapshot ever recorded was 114.127 miles per hour achieved by Russian Alexander Ryazantsev of the Traktor in Russia's Kontinental Hockey League (KHL). The record setting slapshot was performed by Ryazantsev in the league's All-Stars Skills competition held in Riga, Latvia in January 2012. This breaks the record of 110.333 miles per hour set by Denis Kulyash, also of the KHL, which he achieved a year earlier.
The slapshot is the strongest shot that ice hockey players perform. This particular shot got its name from the fact that players strike or "slap" the ice with their hockey stick just behind the puck before following through with the shot. Players slap the ice forcefully and with their body weight to create a bend on the stick. The bend stores energy, which is then released on the puck, sending it flying off with significantly more velocity than just hitting the puck squarely.
In the National Hockey League, the record for the fastest slapshot is held by Zdeno Chara of the Boston Bruins with 108.8 miles per hour. He achieved this record at the 2012 NHL All-Star Game SuperSkills Competition, breaking an earlier record that he also set. The NHL does not recognize the records set in KHL as the puck travels a shorter distance to the net.
