Background: To evaluate the exercise intensity and safety concerns in older adults with controlled hypertension during Spot Marching Exercise (SME).
Materials and Methods: Three older adults with controlled hypertension were instructed to perform SME at a constant individual step rate duration in 6 minutes. Exercise intensity was assessed using % maximum heart rate (%maxHR), % heart rate reserve (%HRR), and rate of perceived breathlessness (RPE) at the end of the exercise. Safety Monitoring: Heart rate (HR), electrocardiogram (ECG), oxygen saturation (SpO2), and respiratory rate (RR) were continuously monitored. Blood pressure (BP) was measured immediately before and after the exercise phase, as well as every two minutes during the resting and recovery phases.
Results: Participants performed SME at individualized step rates (80% of maximum step rate): 70 steps/min for Participant 1, 40 steps/min for Participant 2, and 74 steps/min for Participant 3. Participant 1 achieved moderate to vigorous intensity (86.88% HRmax, 72.45% HRR, and an RPE of 3). Participant 2 achieved light to moderate intensity (66.74% HRmax, 38.00% HRR, and an RPE of 4). Participant 3 achieved light to moderate intensity (61.09% HRmax, 35.17% HRR, and an RPE of 2). For safety concerns, the responses of HR, ECG, BP, RR, and SpO2 remained within the safe exercise range during and after SME. No adverse events were reported during or following SME.
Conclusion: 80 % of self-paced speed in 1 minute of SME maybe safe and alternative approach for cardiopulmonary endurance training in older adults with controlled hypertension.
