Physical Strength or Mental Attitude matters? Some people believe that athletes who have the fittest and strongest body are more likely to achieve success in sports, while others argue that the mental attitude in sports competition is more important than physical conditions. In this essay, both opinions will be discussed and my personal view will be presented at the end. On the one hand, the physical attribute is an essential prerequisite in many sports areas, such as track and field events, which need both strength and skills of athletes. In fact, many athletes who win sports games have experienced very hard training, by which to break their body limits and achieve a better record. Furthermore, when sports teams select professional athletes, physical conditions of applicants, for example, speed, strength, flexibility and so on, are always the most important factors in the selecting criteria. On the other hand, mental attitude also plays a key role in sportsmen's performance. In most finals, the sports skills and the physical attribute of athletes are roughly the same. In this case, the one who can control their own emotions and focus on the game has more chance to win. In my view, the physical attribute is the basis for a person who attempts to be an athlete. However, mental attitude is determinant for the final success. Only with emotional control, can athletes have stable performance and achieve their potential.
