Abstract
Objective. This study aimed to evaluate the impact of physical activity versus high-intensity interval training (HIIT) on the cardiac autonomic nervous system in young sedentary adults.
Method. This randomized pilot study included sedentary adults aged 18 to 40 years, with less than 600 METs in IPAQ and moderate to severe stress on the Perceived Stress Scale. Twenty-eight participants were randomized into three groups: control, HIIT, and physical activity. The HIIT group underwent 30:30 sec circuit training, while the physical activity group engaged in moderate to vigorous aerobic activities for 12 weeks. The control group received education on the importance of exercise. The primary outcome was cardiac autonomic neuropathy assessed using Ewing’s battery of tests, and the secondary outcome was functional capacity.
Result. Significant improvement in cardiac autonomic neuropathy was observed in both the physical activity (p < 0.001) and HIIT groups (p < 0.001), but not in the control group (p = 0.25). Physical activity showed a tendency toward parasympathetic dominance (p = 0.0002), while HIIT showed a tendency toward sympathetic dominance (p = 0.004). Significant improvements in functional capacity were noted in the physical activity (p = 0.002), HIIT (p = 0.001), and control (p = 0.021) groups.
Conclusion. Both physical activity and HIIT significantly improve the autonomic nervous system and functional capacity. However, the type of training has varying impact on the autonomic nervous system.

Abstract
Individuals with intellectual disabilities (ID) often encounter challenges related to both physical and mental well-being. Recognising the widely acknowledged benefits of yoga in promoting overall health, this study aimed to assess the impact of a 12-week yoga program on heart rate variability (HRV), an indicator of autonomic nervous system function, in healthy young female adults with ID. A total of 56 healthy young female adults with ID participated in the study, engaging in a tailored 12-week yoga program. Regular yoga sessions, adapted to their abilities and needs, were provided. HRV was measured using electrocardiography (ECG) at baseline and post-intervention. Age-matched peers with ID, who did not partake in the yoga program constituted the control group. Following the 12-week yoga intervention, a significant (P < 0.05) reduction was observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and pulse pressure (PP) within the yoga group compared to the control group. Short-term HRV analysis revealed a significant (P < 0.05) increase in time domain parameters among the yoga group participants. In the frequency domain, high frequency (HF n.u) exhibited a significant (P < 0.05) increase, whereas low frequency (LF n.u) and LF/HF ratio displayed a significant decrease after yoga practice. This study suggests that yoga practice positively influences heart rate variability in young female adults with ID, potentially enhancing autonomic nervous system function and overall well-being. Implementing yoga programs tailored to the specific needs of individuals with ID may represent a valuable strategy for improving their physical and mental health. Further research is essential to validate these findings and explore the broader implications of integrating yoga into the care and support of individuals with ID.
