Participants will be required to fast from food and
caffeinated beverages (4 hours) and alcohol (24 hours) prior
to the collection of HRV data to reduce possible confounders
that may affect results. The ECG for the HRV will
be obtained for 10 minutes at each data collection session
with the participant in a seated position with limited contact
with the technician.
Low frequency activity, high frequency activity, total HRV
activity and sympathovagal balance will be analyzed to identify
the effects of the intervention compared across the three
arms. This will provide a measure of change in autonomic
activity prior to and after the entire experimental phase.
