Training and Movement Science: New publication on neuroplasticity

The article "Neuroplasticity following short-term strength training occurs at supraspinal level and is specific for the trained Task" has been published in Acta Physiologica. It is known that training, including strength training, follows the specificity principle: "You get what you train for". Here, we observed that after 4 strength training sessions, the corticospinal excitability, but not the spinal excitability, was decreased, but only while performing the trained strength task and not while performing the untrained strength task. The decreased corticospinal excitability can be interpreted as an increased corticospinal efficiency. We concluded that strength training elicits training-specific neuroplasticity at the supraspinal level, which can partly drive the training specific performance improvements seen after longer duration training. These results also indicate that the neural adaptations induced by short-term strength training are similar to the neural adaptations induced by skill training.
