Do college football players enhance body mass naturally?

A few college sportspersons are caught administering forbidden medications. Does it mean that they don’t administer doping products? Less than 1% of college football players have been caught violating anti-doping rules. They have tested positive for steroids and/or other performance-enhancing drugs. Such situation must convince anti-doping agencies that they win in the war on doping. But some suspicions arise. It is believed that many college football players use steroids and/or other related products but they avoid detection successfully.
Why do such suspicions arise? Changes in appearance of college football players lead to controversial points of view. So, changes in body mass of more than 61,000 college football players were recently analyzed by the Associated Press. Results manifested that many college football players enhanced their body weight in short period of time significantly. More than 20 pounds were gotten by over 4,500 college football players during a year. Moreover, near 100 individuals increased the body mass by over 80 pounds during a year. As you see, the gains were evident.
Certain experts claim that these aspects should not trouble anti-doping officials. They note that anti-doping officers shouldn’t subject college football players to drug tests only because they have enhanced body weight essentially.
But other experts have another opinion. Although they agree that it is impossible to affirm that several football players have taken anabolic steroids and/or other related medications, basing just on changes in body mass, they notice that the changes may be a factor that leads to suspicions linked with steroid use. So, such persons that have enhanced body mass in short time should be subjected to drug testing.
Certain college athletes that enhanced body mass evidentially in short period of time were asked about their changes. The athletes affirmed that they had never applied any banned medications. They affirmed that they achieved such dramatic changes naturally. The college athletes noted that they had consumed much food for this purpose. Thus, they affirmed that such essential results were reached by them with the help of appropriate nutrition. According to them, it was not difficult to gain many pounds in short period of time.
