Low-intensity exercise (walking) reduces short-term heart rate asymmetry as measured by Porta's index, reflecting vagal tone withdrawal.

Walking was associated with reduced short-term heart rate asymmetry by Porta's index in healthy youth; hypothesis-generating for autonomic responses and needs prospective validation.
Wang et al. (2018) studied this question.
