Answer:
In some sports there is no difference between offensive or defensive.
Explanation:
In games like tennis, even when it's double tennis so it's two people, the players are neither one nor the other. In sports without set roles such as football or rugby for example, it's not possible to constantly be only offensive or defensive.
But also, players can, depending on the sports, switch between offensive and defensive easily.
In football you get set players with set roles in where to play, especially because it's a team sport.
And a lot of the time the shirts aren't labelled with those two words on them either. So it's a very vague question. But I would mostly just say that in a lot is sports there is no difference.

A nerve impulse is a way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The action potential is the result of ions moving in and out of the cell.
A nerve impulse travels from the dendritic end towards the axonal end. The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in a dendrite of another neuron. A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells.
I'm pretty sure it is prevent injury. Stretching doesn't usually build strength or endurance.
