Abstract

BACKGROUND

Physical exercise is an effective lifestyle intervention to improve blood pressure. Although aerobic sports can be performed anywhere, resistance exercises are traditionally performed at the gym; extending the latter to the home setting may promote an increase in the number of practitioners.

OBJECTIVE

This study aims to evaluate a sensor-based system that guides resistance exercises through ambient lighting and sonification (A/S) feedback in a home setting in 34 study participants who were normotensive and prehypertensive.

METHODS

Participants took part in a 1.5-hour exercise session in which they experienced the A/S feedback (ie, experimental condition) as well as a control condition (ie, no feedback) and a reference condition (ie, verbal feedback through a human remote coach). The system was evaluated for improving exercise form (range of motion, timing, and breathing patterns) as well as psychophysiological experience (perceived exertion, attentional focus, competence, and motivation).

RESULTS

A/S feedback was significantly better than the control for concentric (mean 2.48, SD 0.75 seconds; P<.001) and eccentric (mean 2.92, SD 1.05 seconds; P<.001) contraction times, concentric range of motion consistency (mean 15.64, SD 8.31 cm vs mean 17.94, SD 9.75 cm; P<.001), and perceived exertion (mean 3.37, SD 0.78 vs mean 3.64, SD 0.76; P<.001). However, A/S feedback did not outperform verbal feedback on any of these measures. The breathing technique was best in the control condition (ie, without any feedback). Participants did not show more positive changes in perceived competence with A/S feedback or verbal feedback.

CONCLUSIONS

The system seemed to improve resistance exercise execution and perception in comparison with the control, but did not outperform a human tele-coach. Further research is warranted to improve the breathing technique.

摘要

背景

体育锻炼是改善血压的一种有效生活方式干预措施。尽管有氧运动可以在任何地方进行，但传统上抗阻运动是在健身房进行的；将抗阻运动扩展到家庭环境可能会促使更多人参与。

目的

本研究旨在评估一种基于传感器的系统，该系统通过环境照明和声音反馈（A/S）在家中指导34名血压正常和高血压前期的研究参与者进行抗阻运动。

方法

参与者参加了一次1.5小时的锻炼课程，期间他们体验了A/S反馈（即实验条件）以及对照条件（即无反馈）和参考条件（即通过人工远程教练进行言语反馈）。对该系统在改善运动形式（运动范围、时间和呼吸模式）以及心理生理体验（感知运动强度、注意力焦点、能力和动机）方面进行了评估。

结果

在向心收缩（平均2.48，标准差0.75秒；P<0.001）和离心收缩时间（平均2.92，标准差1.05秒；P<0.001）、向心运动范围一致性（平均15.64，标准差8.31厘米对平均17.94，标准差9.75厘米；P<0.001）以及感知运动强度（平均3.37，标准差0.78对平均3.64，标准差0.76；P<0.001）方面，A/S反馈明显优于对照组。然而，在这些指标中，A/S反馈均未超过言语反馈。呼吸技术在对照条件下（即无任何反馈）最佳。参与者在A/S反馈或言语反馈下，感知能力方面并未表现出更积极的变化。
