In 4 x 100 meter relay race, the acceleration zone is :

Question

Accepted Answer

The correct option is (2):
The acceleration zone in the 4 x 100 meter relay race is precisely 10 meters, according to the conventional and widely followed international athletics rules that were in effect for many years and are frequently referenced in physical education exams. This 10-meter zone is marked on the track immediately preceding the main 20-meter changeover (exchange) zone. The crucial role of this zone is to allow the outgoing (receiving) runner to begin their sprint and build up significant speed *before* the baton arrives. This pre-run ensures that when the actual exchange of the baton occurs inside the 20-meter changeover zone, both the incoming and outgoing runners are moving at a high, similar speed, which is key to a smooth, fast, and ultimately successful baton transfer that maintains the team's momentum.

The incorrect option is (1):
8 meters is incorrect because it is not the standard, officially prescribed distance for the acceleration zone. The international rules of track and field specifically mandate the length of this zone to be 10 meters. An 8-meter zone would provide the outgoing runner with an insufficient distance to generate the necessary speed for an optimal handoff, potentially forcing the exchange to occur at a reduced velocity and thus slowing the team's overall time. The fixed 10-meter length ensures a standardized environment for all teams to maximize their acceleration phase.

The incorrect option is (3):
12 meters is incorrect as it exceeds the established 10-meter length of the acceleration zone. While a longer distance might seem advantageous for the outgoing runner to build more speed, competitive regulations are specific, and 12 meters is not recognized as the official length. Introducing a non-standard zone length would violate the fairness and standardization principles of the race, which require all teams to compete under identical track dimensions and rules.

The incorrect option is (4):
14 meters is incorrect because this measurement is substantially longer than the regulatory 10-meter acceleration zone. Such an extended lead-up would provide a significant, non-standard advantage to the receiving runner, which is contrary to the spirit of uniform competition rules. The rule-makers establish the 10-meter zone to balance the need for acceleration with the necessity of keeping the entire exchange process within a clearly defined and consistent area of the track.
