Which statement best describes the effect of growth and muscular development on motor skills?

• A. Growth occurs independently of strength.
• B. Growth and increased strength contribute to motor skill development.
• C. Only age matters for motor skills.
• D. Environment alone determines motor skills.

Answer: (B)

Growth and muscular development shape motor skill development because the body’s size, strength, and neuromuscular coordination change as a child grows. As bones lengthen and joints mature, movement patterns become possible or more efficient, and as muscles strengthen, the ability to start, stop, and control movements with precision improves. This combination leads to smoother execution, better balance, and the capability to perform more complex skills. It’s not just growth alone, and it’s not only age or environment; growth and increased strength together best explain why motor skills develop.
