Do steroids play any role in tennis?

The Scottish professional tennis player Andy Murray confirms that tennis is not tainted by application of anabolic steroids and other related preparations. He notices that application of doping products doesn’t represent any problem in this sport. He claims that tennis is relatively clean. If you compare this sport to others, you may assure that it is free from doping, according to Andy Murray. But the tennis player realizes that this sport is not completely clean. This man acknowledges that certain tennis players apply prohibited preparations too.
If you take cycling as an example, you may notice that it is associated with allegations regarding doping by the well-known cyclist Lance Armstrong. Cycling commentators and journalists put efforts to prove that doping reigns in other sports too. So, they try to direct attentions of people from cycling to others sports. They claim that usage of steroids and other performance-enhancing drugs is a problem not only in cycling. Tennis turned out to be criticized by them quite often.
Andy Murray decided to respond to such critic words. He confirms that steroids and other related medications don’t play any significant role in tennis. This person mentions about differences between tennis and cycling.
According to the tennis player, while steroids and other performance-enhancing drugs benefit in cycling evidentially, these remedies can’t produce any essential changes in tennis players. This person considers that while strength that is needed in cycling can be added by doping, the skills which are needed in tennis can’t be perfected by steroids and other related drugs.
Actually, similar arguments are used in other sports too. Baseball and basketball players also claim that steroids don’t represent any serious problem in their sports because these substances don’t have ability to enhance performance in their sports.
But it is impossible to doubt about effectiveness of steroids on performance of any athlete. Since these products can enhance strength, speed and endurance, they have great role in tennis and other sports.
