TI  - The implementation of a home-based isometric wall squat intervention using 
      ratings of perceived exertion to select and control exercise intensity: a pilot 
      study in normotensive and pre-hypertensive adults.

AB  - PURPOSE: Isometric exercise (IE) and isometric wall squat (IWS) training have 
      been shown to be effective methods of reducing arterial blood pressure. However, 
      most IE interventions require methodologies and equipment that could present a 
      barrier to participation. Therefore, this study aimed to examine the 
      effectiveness of an accessible RPE prescribed IWS intervention. METHODS: Thirty 
      normotensive and pre-hypertensive adults were randomly assigned to a control 
      group or one of two 4-week home-based IWS intervention groups: the first group 
      conducted IWS exercise where intensity was prescribed and monitored using RPE 
      (RPE-EX), whilst the other used a previously validated HR prescription method 
      (HR-EX). Resting and ambulatory heart rate (HR) and blood pressure (BP) were 
      measured pre- and post-intervention. RESULTS: Minimum clinically important 
      differences (MCID; - 5 mmHg) in SBP and/or DBP were shown in 100% of intervention 
      participants. Statistically significant reductions were shown in resting seated 
      BP (RPE-EX: SBP: - 9 +/- 6, DBP: - 6 +/- 4, MAP: - 6 +/- 3 mmHg; HR-EX: SBP: - 14 +/- 6, 
      DBP: - 6 +/- 4, MAP: - 8 +/- 4 mmHg), supine BP (RPE-EX: SBP: - 8 (- 5), DBP: - 8 
      (- 7), MAP: - 8 (- 4) mmHg; HR-EX: SBP: - 5 (- 4), MAP - 5 (- 4) mmHg), and 
      ambulatory SBP (RPE-EX: - 8 +/- 6 mmHg; HR-EX: - 10 +/- 4 mmHg) following the 
      interventions. There were no statistically significant differences between 
      intervention groups in the magnitude of BP reduction. CONCLUSION: RPE prescribed 
      IWS exercise can provide an effective and more accessible method for reducing BP 
      at home, providing reductions comparable to the current HR-based prescription 
      method.
