Objective of the study was to analyze the modern swimming speed control profiles in the youth 100m freestyle.
Methods and structure of the study. We rated the swimming speed in every 25m segment; stroke pace by five double stroke tests; and the stroke length by segmental swimming speed divided by the relevant stroke pace. The study was run in September-November 2019 at the Russian State Social University’s and Moscow State Medical University’s swimming facilities, with the 10-17 year-old swimmers (n= 26) sampled for the tests.
Results and conclusion. We found the 100-meter freestyle swimming speed control patterns fairly individual, with every analyzed age group found swimming faster the first 25 meters (within one-percent significance rate). This startup acceleration appears largely due to the jump start, since the water start was found of insignificant contribution to the segment 1 speed.
The study found wavelike variations and correlations of the segmental speeds, stroke length and stroke pace in the 100m freestyle in every age group. The findings on the age-specific segmental stroking patterns are recommended being taken in account by the junior swimmers’ training and competitive systems.
The study found the first 25m segment speed in the 100m freestyle being the fastest in the junior sample, with every age group tested with the stroke pace sags on the distance, particularly in the final 25m segment.

Keywords: swimming parameters, junior athletes, various distance segments, front crawl.
