Which statement describes Bernstein's Stage 1 and Stage 2 progression

Which statement describes Bernstein's Stage 1 and Stage 2 progression

• A. Stage 1 freezes degrees of freedom; Stage 2 releases them gradually as proficiency increases
• B. Stage 1 releases all degrees of freedom; Stage 2 freezes them
• C. Stage 1 and Stage 2 both maximize degrees of freedom immediately
• D. Stage 1 is unrelated to Stage 2

Answer: (A)

In Bernstein’s view of motor learning, beginners start by simplifying movement by freezing degrees of freedom to make control easier. In Stage 1, joints and segments are restricted, reducing the number of independent variables the nervous system must coordinate. As learners gain skill, they gradually release those constraints in Stage 2, allowing more joints and segments to contribute to the action. This gradual release makes the movement more efficient and fluid as proficiency increases. For example, a novice learning a throwing motion might stiffen the elbow and wrist; with practice, they begin to use more joints in a coordinated way, improving timing and control. The idea that Stage 1 freezes degrees of freedom and Stage 2 releases them as skill grows best captures Bernstein’s progression. The other options describe releasing all degrees of freedom too early, maximizing them immediately, or treating the stages as unrelated, which doesn’t align with how the developmental sequence works.
