Dose-Response Effects of Inspiratory Muscle Strength Training on Blood Pressure and Vascular Function
This study will assess the dose-response effects of Inspiratory Muscle Strength Training (IMST) in adults with above-normal systolic blood pressure over a 6-week period.
• Age ≥18 years
• Resting SBP ≥120 mmHg as measured during screening 1 \& 2
• Free from serious CV or metabolic diseases as identified by self-report and blood chemistry analysis.
• No contraindications to IMST (recent abdominal surgery, ruptured eardrum, asthma with very low symptom perception, fractured ribs, or pneumothorax)
• Language: English-speaking, with ability to comprehend study materials and instructions.
• Pre-visit Compliance: Willing to comply with pre-visit instructions (avoiding food and caffeine ≥ 3 hours, vigorous exercise, alcohol, and non-prescribed medications ≥ 24 hours) prior to each measurement visit.
• Lifestyle: Non-smokers (defined as self-report of not smoking cigarettes or vaping over the past year).
