Analysis of Underwater Swimming World Record Gains Regularities (Finswimming)

Abstract

In the article we study the dynamics of underwater swimming (namely finswimming sports) world records. World records set in 1974 became a check point in the studies. That was the time when CMAS International Federation introduced particular changes into the contest rules, i.e. they abolished using wet suits, introduced 50-meter underwater dive for male and female, allowed using monofins, and made a decision to hold the first world finswimming championship in Hannover, Germany. We made a comparative analysis of world record gains within 30-year and 10-year periods. The represented research results prove the regularity of world record gains speed. We observed the fact that the most significant result gain was found in sprint races. The attained results allow estimating common factors of speed underwater sports development.
