In fact, there is a big difference between short track speed skating and speed skating.
The former is usually called "short track" and the latter is called "highway".
The two are different in field size, equipment and rules.
As literally, the "short track" has a relatively small area of 30×60 meters. The length of each circle of the oval ice track is 111.12 meters, the width of the straight track is not less than 7 meters, the radius of the curve is 8 meters, and the length of the straight track is 28.85 meters.
The "avenue" site is relatively large, taking place on an ice track with a circumference of 400 meters. The ice track is connected by two straight lines and two 180-degree arcs, which are divided into inner and outer tracks, with a width of 5 meters.
The radius of the inner circle of the inner ice path is 25 meters, and the radius of the inner circle of the outer ice path is 30 meters.
From the point of view of the track setting, the speed skating (excluding group start) track is divided into an inner track and an outer track by the marking line. Competitors must glide in accordance with the rules, with an inner track and an outer track; while the short track speed skating track is There is no subdivision, the players can slide at will, and there is no cross-track situation.

In addition, from the perspective of athletes' wear, short track speed skating and speed skating can also be distinguished.
Speed skaters generally wear hooded jumpsuits to reduce wind resistance, while short-track speed skaters wear safety helmets.
In terms of rules, speed skating individual and team competitions generally start at the same time for each group of two athletes, and for group start events, 6 people start at the same time in a row; short track speed skating 500 meters, 1000 meters and other short distance competitions usually start at the same time. For long distance races of 1500 meters and above, 6 to 8 athletes start at the same time.
