In addition, the distance between the footrest means divided by the support means can be adjusted according to the preferences and physical conditions of the athletes.

At the start of a sprint race, the athlete's record may depend on the starting reaction speed, the repulsive force to push the treads at the start, and the ground reaction on the first foot after the start.

Korean Patent No. 10-0926330 discloses a configuration in which a pressure measuring means is installed on the tread of the starting block to measure the repulsive force pushing the tread when the track athlete starts. Accordingly, it is possible to improve the record of the athlete by identifying the correlation with the starting condition that the athlete can hit the starting block efficiently in the shortest time.

However, such a conventional starting block does not have a means of obtaining information such as ground reaction force applied to the ground by the athlete after the athlete has started the starting block, and thus the starting block is used to improve the athlete's record. There was a limit.

Starting blocks (starting block) is a mechanism used for the start of a short-distance track race, the support of the foot in the inclined upper body of the athlete so that the athlete at the start of the start block in the shortest time.

Sprint racing can be divided into five stages: Start, Start Dash, Medium Sprint, Sprint and Finish. The start is important for these short-range races, as wins and losses are decided for a short time. In order to effectively start short-distance races, fast reaction time and strong repulsion using starting blocks are required, and connection technology to sprint is important.

When a professional athlete sprints, the maximum speed is about 40 km / h. This allows the strong tendon of the Achilles tendon to spring out quickly after contraction, the same principle as the spring springs out after contraction.

During a galloping run, the ground reaction force of the athlete's foot to the ground is 2.5 times the weight. A study of short-range running dynamics revealed that the record of short-range athletes was related to the starting reaction time, the force to push the starting block at the start, and the ground reaction force the foot exerts on the ground at every step.

Therefore, the starting block assembly can comprehensively measure, evaluate, and computerize the factors affecting the track record of the athlete at the start, thereby helping to obtain the optimal starting position according to the athlete's body type and physical condition. To provide.

When the track and field athlete starts according to the start signal, the controller 154 receives the start signal transmitted from the start signal receiver 153. Next, the controller 154 receives from the data receiving device 151 data on the repulsive force transmitted from the pressure measuring means 113 which the athlete presses upon departure. Accordingly, the control unit 154 can calculate the starting reaction time and the starting reaction force of both feet of the athlete.
