How Do Starting Blocks Work for Track Runners?
Starting Blocks Brace a Runner's Foot
-
In a track and field race, runners are assigned to lanes within a running track. To help the runner stay within the assigned lane while maintaining a high level of stability at the beginning of a race, heavy, solid blocks known as starting blocks are used to brace the runner's rear-most foot. Before the use of starting blocks, runners started races from a standing position. In the mid 1880s, runners began starting races from a crouching position to gain a small competitive advantage. Starting blocks were introduced shortly thereafter. The blocks were formally legalized by track and field officials during the 1930s.
Starting Blocks Boost Momentum
-
When a professional or advanced runner starts a race using a starting block, he can gain a considerable momentum advantage by pushing off of the starting block. By using well-developed muscles in the rear-most leg and foot to press against the block, the runner can "jump" off the starting block to shave precious seconds off his race time. This advantage, combined with the increased stability gained from using the devices, can greatly increase a runner's performance.
Starting Blocks Are Not For Everyone
-
While professional and advanced runners can gain a significant advantage by using starting blocks, the devices are not intended for use by newcomers to the sport. Using the devices with new or inexperienced runners is likely to promote bad form and might in some cases injure underdeveloped leg muscles. In addition, newer runners are likely to jump upward--instead of forward--when using a starting block, negating any time advantage and putting the runner at a distinct disadvantage.
