Genetics plays a crucial role in determining an athlete's potential, influencing aspects such as muscle fiber composition, VO2 max, and recovery abilities. These innate characteristics can give some individuals an advantage in specific sports or physical activities.

Training is vital for enhancing physical capabilities, as it improves strength, endurance, speed, and skill. A well-designed training program that aligns with the athlete’s goals and sport-specific demands can lead to significant performance improvements.
