“…For example, quantitative evidence from randomized trials [27] concluded great improvements of FMD after both short-and long-term sedentary behaviors interventions among adults. As for autonomic nervous system function, longer time spent on sitting is linked with poor cardiac autonomic modulation [28] and is even the main lifestyle-related factor associated with this autonomic regulation [29] ; in addition, HRV (the balance between sympathetic and parasympathetic nervous system) was significantly decreased by even shorter term intervention of sedentary behaviors. [30] Physical activity, as an independent lifestyle habit but also strongly linked with sedentary behaviors, has been generally accepted to be associated with lower arterial stiffness, and any intensity of physical activity is favorable to improve PWV in adults.…”

This study aimed to analyze the association of lifestyle habits (physical activity, sleep habits, and eating habits) with cardiovascular risk (arterial stiffness and autonomic nervous system function) among sedentary adults. Sixty adults of sedentariness and physical activity were evaluated by accelerometers; sleep and eating habits were assessed by questionnaires; cardiovascular risks were assessed by pulse wave velocity (PWV), ankle-brachial index, flow mediated dilation, and heart rate variability; circulating biomarkers were also determined. Prolonged sitting (represented by longer maximum length of sedentary bouts, lower length of sedentary breaks, and more total time of sitting) were (P < .05) significantly associated with matrix metalloproteinases, neuropeptide Y, C-reactive protein, peptide Y, ghrelin, and leptin; significant associations (P < .05) were also observed of total time in physical activity with most circulating biomarkers except interleukin-6, tumor necrosis factor-α, and adiponectin. Sleep habits, especially sleep efficiency, were (P < .05) significantly associated with PWV, ankle-brachial index, and circulating biomarkers. Eating habits (including emotional overeating and enjoyment of food) were (P < .05) significantly associated with PWVs and flow mediated dilation; satiety responsiveness and enjoyment of food were (P < .05) significantly associated with low-frequency spectral component expressed in normalized units, high frequency spectral component expressed in normalized units, and ratio between low-frequency/high frequency spectral component expressed in normalized units. The findings indicated that several lifestyle habits among sedentary adults were closely associated with increased cardiovascular risk. Sedentary people were encouraged to live with sufficient physical activity, good sleep, and healthy eating habits for decreasing arterial stiffness and balancing autonomic nervous function.

Background: The current study investigated the chronic effects of high-volume moderate-intensity training and low-volume high-intensity training on heart rate variability (HRV) and arterial stiffness in sedentary adult men. Materials and methods: Forty-five males (age: 42± 5.7 yrs.) were randomly assigned into control group (n=15), high-volume moderate-intensity training (HVMIT) (n=15), and low-volume high-intensity training (LVHIT) (n=15). The HVMIT group ran three times per week, on the treadmill at 50% to 60% of VO2max for 45 to 60 minutes, while the LVHIT trained at 70% to 85% of VO2max for 25 to 40 minutes. Both training programs were equated by caloric expenditure. HRV, Pulse Wave Velocity (PWV), hemodynamic variables, and body composition were measured before and after 12 weeks.Results: Both protocols (HVMIT and LVHIT) significantly increased the Standard deviation of NN intervals (SDNN) and High-frequency (HF) bands after 12 weeks (p ˂ 0.05). The LF/HF ratio decreased significantly in both training groups (p ˂ 0.05). However, these changes were significantly greater in the LVHIT protocol (p ˂ 0.05). Furthermore, the Root mean square of successive RR interval differences (RMSSD) significantly increased only in the LVHIT protocol (P ˂ 0.05). Moreover, a significant decrease in low-frequency (LF) and PWV was only observed following the LVHIT protocol (P ˂ 0.05). Conclusion: This study indicates that the LVHIT protocol is more effective and efficient for improving HRV variables and PWV than the HVMIT protocol.

“…The negative association of sedentary time with HRV implies time in this behaviour acts in a deleterious manner on vagal tone, postulated to be attributed to prolonged sympathetic activation resulting in increases in resting HR, BP and a decreased stroke volume (Hughson &Shoemaker, 2015). Moreover, the negative influence of sedentary time was further corroborated by Farah et al (2020), who found increased recreational sedentary time to act in a deleterious manner on parasympathetic activity in adolescents. However, contrary findings in adolescents suggest device-based assessment of sedentary time was not independently associated with parasympathetic activation .…”

Investigating the relationship between habitual physical activity and cardiovascular health in healthy and clinical populations

Physical activity (PA) is beneficial for arterial and autonomic health and, subsequently, cardiovascular disease risk. However, fundamental questions remain regarding the relationship between PA and health, the relative importance of the volume, intensity or composition of PA, and whether this differs in chronic conditions. Therefore, the aim of this thesis was to explore the influence of movement behaviours on key cardiovascular risk factors in healthy populations and those with T1D using novel methods and analysis techniques. Chapter 4 revealed that, contrary to expectation, the composition of daily movement and sleep behaviours was not associated with arterial stiffness in healthy children, with the reallocation of time between any behaviours not predicting significant change in arterial stiffness. It was hypothesised that this may be related to the measurement duration being insufficient to reflect habitual PA and its health-associated fluctuations. Therefore, a 28-day measurement period was used in Chapter 5, which revealed that, whilst there was minimal fluctuation in movement behaviours, PA metrics derived from 28 days were more strongly associated with cardiovascular health markers. Using a similar measurement protocol, children with type I diabetes (T1D) were found to engage in more light and less moderate-to-vigorous physical activity (MVPA) than healthy peers and were characterised by poorer arterial stiffness and autonomic function (Chapter 6). Importantly, Chapter 6 suggested that the intensity of PA was more influential than the volume. Subsequently, Chapter 7 supported this contention, revealing that the reallocation of time from any behaviour to MVPA was the most potent stimulus to cardiovascular health in T1D. Overall, this thesis demonstrates that the composition and the relative importance of the volume and intensity of PA must be considered when investigating the relationship with health. The findings highlight key targets for future interventions seeking to enhance the cardiovascular function of youth, especially in T1D.
