📖 About the Paper

Overview

This 2021 meta-analysis examines over two decades of research on how attentional focus affects motor performance and learning. The study specifically compares:

1. External focus (EF) - attention on intended movement effects
2. Internal focus (IF) - attention on body movements

Key Findings Relevant to Swing Genius

1. Performance Benefits

• External focus produced significantly better performance outcomes (Hedges' g = 0.264)
• External focus led to more efficient neuromuscular activation (Hedges' g = 0.833)
• Benefits were consistent across:
  • Age groups
  • Skill levels
  • Health conditions

2. Learning Benefits

• External focus improved retention (Hedges' g = 0.583)
• External focus enhanced transfer to new situations (Hedges' g = 0.584)
• More distal external focus points were more effective than proximal ones (Hedges' g = 0.224)

Application in Swing Genius

Design Validation
