How humans learn movement
From repetition to skill
Motor learning is a process of stabilizing effective movement solutions under changing environmental and internal constraints. Experts are not simply stronger versions of novices; they often exhibit more efficient coordination, reduced unnecessary co-contraction, better anticipatory postural control, and more robust error correction. Practice structure, feedback timing, and contextual interference all influence retention and transfer.
Motor learning vocabulary
Practice conditions
Blocked practice
- High short-term performance
- Lower contextual variability
- Useful for early familiarization
Random practice
- Harder during practice
- Often better retention
- Useful for skill robustness
Which practice structure often improves long-term retention despite lower immediate performance?
Variable practice often increases retention and transfer by forcing adaptable movement solutions.
Correct answer: Random or variable practice
What is one reason experts may appear smoother or more economical in movement?
Better coordination can reduce wasted effort and improve movement economy.
Correct answer: They use more efficient coordination and less unnecessary muscle activation.
Coaching insight
Feedback should usually be specific, actionable, and tapered over time so learners do not become dependent on constant external correction.
A skill-acquisition sequence for complex lifts or sports skills
-
1
Step 1: Establish a safe, stable starting pattern with clear constraints.
-
2
Step 2: Add variability gradually to challenge perception and decision-making.
-
3
Step 3: Use feedback sparingly and target the most important error at a time.
-
4
Step 4: Test retention after a delay to see whether learning, not just performance, occurred.
Which statement best describes intrinsic feedback?
Intrinsic feedback comes from proprioception, vision, vestibular cues, and other bodily sensations.
Correct answer: Information from the body and senses
