AbstractThe role of physiological signals has a large impact on driver monitoring systems, since it tells something about the human state. This work addresses the recursive probabilistic inference problem in time-varying linear dynamic systems to incorporate invariance into the task of heart rate estimation from face videos under realistic conditions. The invariance encapsulates motion as well as varying illumination conditions in order to accurately estimate vitality parameters from human faces using conventional camera technology. The solution is based on the canonical state space representation of an Itô process and a Wiener velocity model. Empirical results yield to excellent real-time and estimation performance of heart rates in presence of disturbing factors, like rigid head motion, talking, facial expressions and natural illumination conditions making the process of human state estimation from face videos applicable in a much broader sense, pushing the technology towards advanced driver monitoring systems.

Abstract Funding Acknowledgements Type of funding sources: None. Background During Ramadan, alterations in the daily patterns of sleep, activities and medication timing might contribute to changes in blood pressure (BP) and heart rate among hypertensive patients. The aim of this study was to examine the effect of medication timing during Ramadan on blood pressure and heart rate in hypertensive subjects taking their treatment once daily. Methods The study prospectively recruited 44 hypertensive patients between April and June 2019, followed up at the cardiology department of our   Hospital. A 24-hour pressure monitoring was carried out during two periods: prior to Ramadan and during the last ten days of Ramadan. Results We studied 29 women and 15 men, mean age was 58.7 years. 34% of the patients were diabetics and 16% had coronaropathy. 46% of the patients were on monotherapy, 43% on dual therapy and 11% on a triple antihypertensive therapy. During Ramadan, 57% of the patients took their treatment during the dinner (group1), whereas 43% took their treatment during the Shour (group 2). Average 24hour blood pressure in the whole group was 129 ± 18/74 ± 10 mmHg before Ramadan and 129 ± 19/74 ± 10 mmHg during Ramadan (p > 0.05). Daytime and nighttime mean values of systolic and diastolic blood pressure as well as mean values of heart rate were not different between both periods regardless of age and gender. However, during Ramadan, those who took their treatment after dinner had significant higher values of 24 hour systolic BP, awake systolic and diastolic BP, asleep systolic and diastolic BP than those who took their treatment with the shour (p < 0.05). Conclusion In this study, there were no significant changes in systolic and diastolic blood pressures as well as heart rate during the 2 periods. However, during Ramadan, a slight superiority of taking the treatment with the shour is observed.

Driver inattention is a major contributor to road crashes. The emerging of new driver monitoring systems represents an opportunity for researchers to explore new data sources to understand driver inattention, even if the technology was not developed with this purpose in mind. This study is based on retrospective data obtained from two driver monitoring systems to study distraction and drowsiness risk factors. The data includes information about the trips performed by 330 drivers and corresponding distraction and drowsiness alerts emitted by the systems. The drivers’ historical travel data allowed defining two groups with different mobility patterns (short-distance and long-distance drivers) through a cluster analysis. Then, the impacts of the driver’s profile and trip characteristics (e.g., driving time, average speed, and breaking time and frequency) on inattention were analyzed using ordered probit models. The results show that long-distance drivers, typically associated with professionals, are less prone to distraction and drowsiness than short-distance drivers. The driving time increases the probability of inattention, while the breaking frequency is more important to mitigate inattention than the breaking time. Higher average speeds increase the inattention risk, being associated with road facilities featuring a monotonous driving environment.

Study aim: The aim of the work was to determine the effects of an 18-week training programme on the economics of running at a speed corresponding to the lactate threshold of an athlete from the track-and-field section of AZS AWF (University of Physical Education) Kraków. In addition, the objective was to determine the average heart rate and speed during a 10-km during in relation to threshold values for these parameters. Materials and methods: In the study, heart rate and speed at lactate threshold were determined using the pitch test. The indirect calorimetry method was applied to assess energy expenditure of the run. The training work carried out by the study participant was subject to registration and quantitative as well as qualitative analysis. Results: Observations indicated that the implemented training programme resulted in a reduction of energy expenditure by 6.32% when running at threshold speed. During the 10-km competitive run, the studied athlete obtained an average heart rate and running speed at a level corresponding to 109% and 108% (respectively) of the threshold values for the specified parameters. Conclusions: The proposed training programme had a positive effect on running economics at threshold speed. It was shown that the average heart rate and speed obtained during the competition over a distance of 10 km exceeded the threshold values of the mentioned parameters by 9 and 8%, respectively.

Indoor play for pay centers (PPCs) have become very popular over the last decade. Due to the group format and physical design, the PPC promotes fastpaced large muscle activity that appears to increase the heart rate of prepubescent participants. The purpose of this study was to measure children’s heart rate response to self-directed play at a PPC. Fourteen boys and girls (age = 7.8 ± 1.8 years) participated in a treadmill test to determine their maximal heart rate (MHR). On a separate day these same children played freely for 20 min over a 5,000 square foot multilevel PPC while their heart rate was monitored. The average MHR obtained in the laboratory was 204 ± 1.3 bpm, while the average heart rate during free play was 158 ± 38.5 or 77% of the MHR observed in the laboratory. These results suggest that the PPC promotes an increase in heart rate among self-directed prepubescent subjects.

This study compared the cardiovascular responses and energy costs of new and traditional screen based entertainments, as played by twenty 9- to 12-year-old children. Playing traditional electronic games resulted in little change to heart rate or energy expenditure compared with watching a DVD. In contrast, playing an active-input game resulted in a 59% increase in heart rate (p < .001) and a 224% increase in energy expenditure (p < .001) for boys and girls. The average heart rate of 130 bpm and energy expenditure of 0.13 kcal · min−1 · kg−1 achieved during active-input game use equates with moderate intensity activities such as basketball and jogging. Active-input electronic games might provide children with opportunities to engage with technology and be physically active at the same time.
