“…FITT criteria have enabled broad research insights to be efficiently organized toward the establishment of a dose-response relationship between increased weekly aerobic physical activity (Intensity * Timing * Frequency) and improved health and reduced disease risk (Barisic et al, 2011;Arem et al, 2015;Rhodes et al, 2017 Similar links between acute music-induced autonomic changes and sustained modulations of autonomic tone are likely (Figure 1). However, studies of the effects of repeated music engagement on autonomic tone have only considered and prescribed FTT (Frequency, Timing, and Type) criteria (Takahashi and Matsushita, 2006;Le Roux et al, 2007;Okada et al, 2009;Chuang et al, 2011;Chlan et al, 2013;Hu et al, 2015;Helsing et al, 2016;Kunikullaya et al, 2016;Finn and Fancourt, 2018;Ribeiro et al, 2018;Fancourt and Finn, 2020;Mojtabavi et al, 2020;McCrary et al, 2021). Similarly, observational and intervention studies of the effects of repeated music engagement on health conditions linked to autonomic tone have not assessed and/or controlled the acute autonomic responses to music-making or listening (Fancourt and Finn, 2020;McCrary et al, 2021).…”
