What is one result of regular practice in motor skill development?

Regular practice in motor skill development leads to enhanced coordination, which is a key result of refining motor skills over time. When individuals engage in consistent practice, their movements become more fluid and controlled. This improvement is largely due to the brain's ability to create and strengthen neural pathways associated with motor skills, resulting in more efficient movement patterns.

Greater coordination means that an individual can execute complex physical tasks with higher precision and smoother transitions between movements. Additionally, as coordination improves, other aspects of performance tend to benefit as well, such as balance, timing, and reaction speed.

In contrast to enhanced coordination, other options do not align with the typical outcomes of practicing motor skills. For example, increased muscle mass may occur due to strength training rather than motor skill practice alone. Similarly, skill retention is generally improved rather than reduced; practice is crucial for retaining skills long-term. Lastly, while practice can sometimes reduce the negative impact of environmental factors, it does not inherently lead to less environmental influence on motor performance. Thus, the most accurate outcome of regular practice is indeed enhanced coordination.
