Explosive strength is defined as the ability to exert maximum force in minimal time, which can be quantified as the product of strength and speed; mathematically expressed as:

$\text{Explosive Strength} = \text{Strength} \times \text{Speed}$

Explosive strength is crucial for several reasons:

1. It allows Anna to explode from the blocks, giving her a critical advantage and a head start in the race.
2. It enables her to run faster initially, which is essential for gaining a crucial lead in the early stages of the race.
3. At the end of the race, having explosive strength allows Anna to maximize her final burst of speed, helping her to secure a better finishing position by accelerating to the finish line.
4. Additionally, explosive strength permits her to make quick accelerations during the race, which can be vital for either breaking away from competitors or defending her position.
