What positive effect does high-intensity interval training (HIT) have?

High-intensity interval training (HIT) is recognized for its beneficial effects on various physiological adaptations, particularly in the context of stroke rehabilitation and overall movement analysis. One of the key advantages of HIT is its ability to enhance cortical and spinal plasticity. This refers to the brain's and spinal cord's capacity to reorganize and adapt neural connections in response to training and repetition.

Through HIT, individuals can stimulate the nervous system more effectively than with steady-state exercises. The repeated bouts of high-intensity effort can lead to increased release of neurotrophic factors, which support neuron survival and promote neural growth. As a result, patients, especially those recovering from a stroke, experience improved motor functions and better rehabilitation outcomes.

The integration of intense physical activity in HIT fosters synaptic strengthening and the creation of new synaptic pathways, facilitating the brain's ability to learn and adapt to motor tasks. This is crucial in rehabilitation strategies, as it can help restore lost function and improve quality of life. Therefore, the positive effect of HIT on cortical and spinal plasticity stands out as a significant reason to incorporate this form of training into rehabilitation programs.
