Do college athletes increase body weight without steroids?

A few college sportspersons are caught administering forbidden products. Does it mean that they don’t take performance-enhancing drugs? 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 assure anti-doping agencies that they win in the war on doping. But several suspicions arise. It is believed that numerous college football players apply steroids and/or other related products but they avoid detection successfully.
Why do such suspicions appear? Changes in physique of college football players cause controversial statements. So, changes in body mass of more than 61,000 college football players were recently analyzed by the Associated Press. Results displayed that numerous college football players enhanced their body weight in short period of time significantly. More than 20 pounds were gained by over 4,500 college football players during a year. Furthermore, circa 100 persons enhanced the body weight by more than 80 pounds during a year. As you see, the gains were obvious.
Some experts affirm that these aspects should not trouble anti-doping officials. They notice that anti-doping officers shouldn’t subject college football players to drug tests just because they have increased body mass evidentially.
But other specialists have another opinion. However they agree that it is impossible to be sure that several football players have administered steroids and/or other related medicines, basing just upon changes in body mass, they note that the changes may be a factor which causes suspicions linked with administration of steroids. Thus, such individuals that have enhanced body weight in short period of time should be subjected to drug testing.
Some college athletes that increased body weight significantly in short period of time were asked about their changes. The athletes affirmed that they had never used any banned drugs. They claimed that they reached such dramatic changes naturally. The college athletes noted that they had consumed much food for this purpose. So, they claimed that such obvious results were achieved by them because of proper diets. According to them, it was not difficult to get many pounds in short period of time.
