There is a little piece of your rod that is called the guide. The guides are the little loops that start at the handle and decrease in size as they reach the end of the pole. Are they just to hold the fishing line or do they do more?

The trout fishing guide does serve a purpose other than holding your line in place. The size of the loops makes it easier to cast. They cut down on the friction of the line when it is flying out of out of your reel. Another very important function of the guide is to gather the loops that come out of the reel. The line loops can really get in the way of your cast. A well designed rod with the correct guide placements will drastically cut down on the wind resistance during your cast.
