Pacing in World-Class Age Group Swimmers in 100 and 200 m Freestyle, Backstroke, Breaststroke, and Butterfly The pacing for swimming was investigated in the pool swimming for freestyle in elite pigs as well as master’s swimming, over the pacing in master squids, which compete on world class level in the back swimming, breast swimming and dolphin, but little is known. The aim of this study was to investigate the pacing of master squids that approached in the four individual disciplines (freestyle, back, chest and dolphin) on world-class level at 100 and 200 m. Data was analyzed at 18,187 finishers who participated in four Fina Champion Championships between 2014 and 2019.The sample comprised 3,334 women and 14'853 men. The swimming speed decreased with increasing age.Freestyle was the fastest and bundle swimming the slowest style.Women and men were in 100 m faster than in 200 meters. Back was the style with the lowest and dolphin with the highest variation coefficient of the swimming speed.100 meters had a higher variation coefficient in the swimming speed as a breast swimming.In the second round, the swimming speed for 100 m decreased for all styles and all ages.For 200 m, the swimming speed in the first round was the fastest for all styles and all ages.
In summary, the FINA World Championships showed the unique property that, taking into account all participants, the swimming speed with increasing age decreased, women and men were 100 m faster than 200 m, freestyle was the fastest style and the largest increase in the floating time for 100 mAll styles and all ages occurred in the second round, and for 200 m, the swimming speed for all styles and age groups was the fastest of the first round.
