Practice and specific training can improve components of skill-related fitness limited by heredity.

Training and practice can indeed enhance components of skill-related fitness that are influenced by genetic factors. While heredity plays a significant role in an individual's baseline abilities, such as muscle fiber composition, coordination, and reaction time, the practice can lead to noticeable improvements in these areas. For example, an athlete may possess genetic advantages in speed or agility, but through dedicated training, their performance can reach new heights.

Regular and focused practice can help refine techniques, improve neuromuscular coordination, and enhance overall skill execution, allowing individuals to maximize their potential regardless of their genetic predispositions. Skill-related fitness elements, such as agility, balance, coordination, power, reaction time, and speed, can all see substantial gains when one engages in specific training regimens and practice routines tailored to developing these skills.

This understanding aligns with the principles of adaptability and neuroplasticity, showing that the body can adapt to the demands placed upon it through targeted training, leading to improvements over time in spite of genetic limitations.
