Assisting Home-Based Resistance Training for Normotensive and Prehypertensive Individuals Using Ambient Lighting and...

Area of Science:

• Exercise Science
• Human-Computer Interaction
• Biomedical Engineering

Background:

• Physical exercise, particularly resistance training, is crucial for managing blood pressure.
• Traditional resistance exercises are gym-based, limiting accessibility.
• Adapting resistance training for home environments can increase participation.

Purpose of the Study:

• To evaluate a sensor-based system providing ambient lighting and sonification (A/S) feedback for home-based resistance exercises.
• To assess the system's impact on exercise form and psychophysiological experience in normotensive and prehypertensive individuals.

Main Methods:

• A 1.5-hour session comparing A/S feedback, no feedback (control), and remote verbal coaching (reference).
• Evaluation focused on range of motion, timing, breathing patterns, perceived exertion, and motivation.
• 34 participants (normotensive and prehypertensive) were involved.

Main Results:

• A/S feedback significantly improved contraction timing and range of motion consistency over the control.
• Perceived exertion was lower with A/S feedback compared to the control.
• A/S feedback did not surpass verbal coaching effectiveness; breathing technique was best without feedback.

Conclusions:

• The A/S system enhances resistance exercise execution and perception versus no feedback in a home setting.
• The system's performance was comparable to, but not superior to, remote human coaching.
• Further development is needed to optimize breathing technique guidance.
