I have same comments and suggestion for your essay.grammatical issues
lots of sport programs
"Lots of .." is good idea to express things in a large number while I do not think that such a expression is a formal word for IELTS essay or academic writing. Therefore, I suggest you to change " lots of..".
I firmly argue that both opinions result in some effects to juveniles.
Have you checked your dictionary whether "to" is collocate or not with "effect"?

In recent years, lots of sport programs have appeared in some television channels over the world. This trend causes other people to think that the programs discourage teenagers to get involved in a sport themselves. Although these thoughts have different perspectives, I firmly argue that both opinions result in some effects to juveniles.
As a matter of fact, I am confused about your introductory paragraph inasmuch as your thesis statement said that "both opinions" but in your first paragraph, you just wrote one opinion and then you state that "both opinions". However, the question does not state that there are two opinions while I suggest you that you should raise other statement to make your introductory paragraph becoming discussion. Thus, here my version for your introductory paragraph :Screen entertaining devices have made a profound influence on juveniles. Thanks to such a fact, young people are affected by television programs which they see inasmuch as television most nearly represent a real experience of most youth generations throughout the world. This situation has generate a great deal of discussion as sports programs in TV has affected young people to do sports activities. Some multimedia analysts argue that young people are more likely to leave physical exercises as the popularity of sports programs are increasing. However, a group of former athletes have taken against the argument in that they think it can encourage juveniles to do more sport activities. I am of opinion, there are many factors which discourage young people to do sports such as lifestyle, video games, and their study.
