The acceptability of a novel seismocardiography device for measuring VO2 max in a workplace setting: a mixed methods approach
Executive Summary
This study evaluated the acceptability of a novel seismocardiography (SCG) device for measuring VO2 max in workplace health screenings compared to sub-maximal exercise testing. Using mixed methods, the SCG device demonstrated higher acceptability in domains such as 'affective attitude' and 'burden,' with significant statistical differences (p < 0.001). However, barriers such as limited understanding of the device's effectiveness and coherence were identified, emphasizing the need for practitioner training to enhance adoption in workplace settings.
Answer Machine Insights
Q: What were the main advantages of the SCG device compared to sub-maximal exercise testing?
The SCG device was perceived as less burdensome and more comfortable, requiring minimal effort and no physical exertion.
Employees considered the SCG assessment to require minimal effort and reflected that it was both non-invasive and did not require changing clothes or getting ‘hot and sweaty’ at work.
Q: What barriers were identified for the SCG device's adoption in workplace settings?
Barriers included limited understanding of the device's effectiveness and coherence, as well as practical concerns like internet connectivity and privacy during chest placement.
Employees generally said they did not understand the results from the SCG device or how they were generated, and, therefore, didn’t appreciate the significance of the results.
Key Results
SCG device scored significantly higher in 'affective attitude' (M = 9.06 ± 1.14) compared to sub-maximal exercise testing (M = 7.94 ± 1.79), p = 0.001.
SCG device scored significantly higher in 'burden' (M = 9.16 ± 0.55) compared to sub-maximal exercise testing (M = 7.41 ± 1.45), p < 0.001.
