Which is an example of bilateral transfer?

• A. A soccer player learning to kick with his weaker foot.
• B. Improving dynamic strength to start races.
• C. From 3-on-3 basketball to the full game.
• D. From learning that long levers aid in throwing a javelin.

Answer: (A)

Bilateral transfer is when practicing a skill with one limb leads to improvements in the same skill with the opposite limb. This happens because the motor learning and neural adjustments made during training can transfer across hemispheres, so the unpracticed limb can perform better even without direct practice. In this case, a soccer player who trains kicking with the stronger foot often sees better kicking accuracy and power from the weaker foot as well, due to this cross-education effect. The other scenarios describe learning or performance improvements that transfer across different tasks or contexts rather than between limbs, so they don’t illustrate bilateral transfer.
