Why is it Much Harder to Break the 400m World Record Than the 100m World Record?
The 100m world record has been broken numerous times in recent decades, with Usain Bolt's record of 9.58 seconds set in 2009 standing as the current benchmark. In contrast, the 400m world record has remained unchanged since 1999, when Michael Johnson ran 43.18 seconds.
There are several reasons why it is much more difficult to break the 400m world record than the 100m world record.
- Lactate accumulation: The 400m is run at a higher intensity than the 100m, resulting in the accumulation of lactate in the muscles. This lactate can lead to fatigue and hinder performance.
- Energy systems: The 100m relies primarily on the phosphagen energy system, which provides short bursts of energy. The 400m, on the other hand, requires the use of both the phosphagen and lactate energy systems, which makes it more difficult to maintain a high speed throughout the race.
- Anaerobic capacity: The 400m requires a greater anaerobic capacity, which is the ability to produce energy without oxygen. This is because the race is run at a high intensity for an extended period.
- Technical demands: The 400m is a technical event that requires runners to maintain a good running form and pace throughout the race. This can be difficult to master, and even minor errors can lead to a significant loss of speed.
