“….analyze the pacing profiles of the world’s top 800 meter annual
performances between 2010 and 2016, comparing men’s and women’s
strategies. A total of 142 performances were characterized for overall
race times and 0-to-200-m, 200-to-400-m, 400-to-600-m, and 600-to-800-m
split times using available footage…..”
.
“The mean speed of
the men’s 800-m was 7.73 meters per second, with the 0-to-200-m split
faster than the others. After the first split, the speed decreased significantly during the 3 subsequent splits.”
.
“The mean speed of the women’s 800-m was 6.77 meters per second, with a
significative variation in speed during the race. The first split was
faster than the others. During the rest of the race, speed was almost
constant, and no difference was observed between the other splits.”
.
“Comparison between men and women revealed that there was an
interaction between split and gender, showing a different pacing
behavior in 800-m competitions. The world’s best 800-m performances
revealed an important difference in the pacing profile between men and
women. Tactics could play a greater role in this difference, but
physiological and behavioral characteristics are likely also important.”

“….assess tactical and performance factors associated with
progression from qualification rounds in the 800-m and 1500-m running
events at the 2017….World Championships.”
.
“Race positions at
the end of each 400-m lap remained more stable through 800-m races than
1500-m races. Probability of automatic qualification decreased with
both race position and rank order lap times on each lap, although rank
order lap times accounted for a higher degree of shared variance than
did intermediate position. In the 1500-m event, fastest losers ran at a
higher percentage of season’s best speed and adopted positions closer to
the race lead in the early stages. This was not the case in the 800-m.”
.
“Intermediate positioning and the ability to produce a fast final race
segment are strongly related to advancement from qualification rounds in
middle-distance running events. The adoption of a more “risky” strategy
characterized by higher speeds relative to season’s best may be
associated with an increased likelihood of qualification as fastest
losers in the 1500-m event.”
