EARLY MOTOR UNIT CONDUCTION VELOCITY CHANGES TO HIIT VERSUS CONTINOUS TRAINING

Moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) are associated with different adjustments in motor output. Changes in motor unit (MU) peripheral properties may contribute to these adjustments, but this is yet to be elucidated. This study evaluated early changes in MU conduction velocity (MUCV) and MU action potential (MUAP) amplitude following two weeks of either HIIT or MICT.
