Ambulatory measures
Following the baseline and post-intervention testing sessions, participants were fitted with an ambulatory blood pressure (AMBP) monitor (Welch Allyn 6100, Welch Allyn Inc, NY, USA). CON participants had the AMBP monitor fitted at the end of the laboratory testing session, whilst the intervention participants were given 24-h to recover from the IWS exercise before the measurements were taken. As such, intervention participants were shown how to fit, turn on, and start the ambulatory BP cuff and were instructed to do so 24–48 h after completion of the preceding laboratory sessions. Once the device was fitted to the participant, it was turned on and a manual measurement was collected. This first measurement initiated a 24-h data collection period. Participants were asked to avoid tight fitting clothing and exercise, and to maintain their normal dietary habits during this 24-h monitoring period. The device was programmed to take measurements every 20–30 min during the day and every 30–60 min at night. The same AMBP monitor was used by each participant for both 24 h AMBP measurements (pre- and post-intervention).
