Motion of the skater in terms of position, direction and speed at the beginning during and end of the race details summary is given below

Explanation:

Races in speed skating represent head-to-head competitions performed during multiple series (the rank but not the time qualifying for the next round are important), where strategic aspects are thought to play an important role for success.

This study examined the relationship between starting and finishing position performed in six short track ice speed skating events (3 European Championships, 3 World Championships) over a four year period (321 female and 386 male individual races finished).

Associations were analyzed for effects of race distance (500 m, 1000 m, 1500 m, and 3000 m) and qualifying round (preliminaries, heats, quarter-finals, semi-finals, and final). Kendall's tau-b rank-correlation revealed that regardless of athletes' sex, the size of correlation between starting and finishing position decreases with race distance, which was highest and positive in the 500 m races (women: τ=0.28, P0.05). This finding suggests a shift in pacing strategy, with skaters reducing their effort to initially skate in a front position as race distance increased (e. g., in order to conserve some energetic ressources for an end spurt).

The size of correlation increases with qualifying round, which was lowest in the preliminaries (women: τ = - 0.02, P>0.05; men: τ=0.07, P>0.05) and highest in the finals (women: τ=0.34, P.

the present study examines the association between starting and finishing positions in female and male elite athletes, who performed races of different lengths during a series of official competitions.

To see whether the number of skaters per race (i. e., 4, 6, and 8 skaters during 500/1000 m, 1500 m, and 3000m, respectively) could have influenced the relation-ship between starting and finishing position, we conducted a sensitivity analysis in which, irrespective of race distance,
