Key result
Whole-body vibration increases mean RR interval while mental workload reduces it, demonstrating autonomic dysregulation.
Why the study?
Whole-body vibration and mental workload are common stressors among drivers, but their individual and combined effects on the autonomic nervous system are not well understood.
Does exposure to whole-body vibration and mental workload affect autonomic nervous system responses?
Comparison

May indicate occupational autonomic risks from vibration and stress; hypothesis-generating and requires validation before clinical adoption.
Does exposure to whole-body vibration and mental workload affect autonomic nervous system responses?
p-value: p=0.008
Exposure to whole-body vibration and mental workload alters heart rate variability, indicating dysregulation of the autonomic nervous system and an imbalance in sympatho-vagal control.
Jalilian et al. (2019) studied this question. Whole-body vibration (WBV) and mental workload (MWL) was evaluated on Mean RR interval and heart rate variability parameters (p=0.008). Exposure to whole-body vibration significantly increased the mean RR interval (p=0.008), whereas mental workload significantly reduced it (p=0.02), demonstrating autonomic nervous system dysregulation.
