“…For HRV assessments, R-R intervals were analyzed from 1-minute recordings with investigators (MA, KR) visually inspecting all R-R intervals for any premature beats and artifact/noise. One-minute recordings have been reported to be valid and reliable for the assessment of HRV in a range of population including children 2,[19][20][21] . All R-R intervals were exported from the ECG via the manufacturer's software (Medset, Hamburg, Germany) for later analysis by customized software (Kubios HRV software, version 2.1, Department of Applied Physics, University of Eastern Finland, Kuopio, Finland).…”

Background: Asthma and obesity are becoming increasingly common among children. Such conditions are known to negatively affect both cardiac autonomic function and oxidative stress. We therefore investigated the heart rate variability (HRV) and oxidative (malondialdehyde, MDA) response to exercise within a high humidity environment (~65%) in obese and lightweight asthmatic children.Methods: Forty-two children participated in this study and were categorized into four groups: obese asthmatic (OA, n = 10), obese non-asthmatic (ONA, n = 15), lightweight asthmatic (LA, n = 10), and lightweight non-asthmatic (LNA, n = 7). Time-domain and nonlinear indices of HRV were assessed at rest, during, and immediately after exercise. Further, saliva samples were collected immediately before and after exercise and analysed for the determination of MDA.Results: HRV significantly decreased during and after exercise compared to baseline (P < 0.05) with short-term fractal scaling exponent (α1) for the LNA group significantly smaller than the OA group after exercise (P < 0.05). In contrast, the long-term fractal scaling exponent (α2) was greater after exercise compared to baseline and during exercise for all groups (P<0.05). MDA significantly decreased after exercise compared to baseline (P<0.05).We also found significant correlations after exercise between salivary levels of MDA with HRV components (i.e., RMSSD, SD1, and α2) in asthmatic groups (all P<0.05). Conclusions:Our findings showed that exercise in high humidity environment does not significantly differentiate the autonomic response among children with various conditions (i.e., obese, asthmatic and healthy). However, a significant relationship was found between HRV and MDA in asthmatic children after exercise, highlighting the inter-relationship between oxidative stress markers and autonomic function in asthmatic children.

“…Drivers transporting firewood must be able to load, transfer and unload both leveled assortments of firewood, stems, or whole trees. Hauling loads of different dimensions affects the mental and physical load of drivers and, consequently, the level of work performance [3,4]. With the length of the exposure, different types of health problems develop in the background, with varying intensity and visibility.…”

Our research aimed to quantify stress load in drivers by monitoring the load on the radial extensor carpi radialis (musculus extensor carpi radialis) on different types of forest and other categories of roads. We observed changes in the electrical potential of skeletal muscles using electromyographic measurements and changes in heart rate using a Biofeedback 2000 x-pert recorder. We measured the loading of drivers during the normal operation of timber trucks and timber trucks with trailers, while the reference measurements took place in a passenger car. We obtained descriptive statistics from the individual measurements and evaluated the normality of the measured data. Differences in muscle load increased when driving on lower-grade roads. The muscle load increased significantly, especially when passing through villages, inversely proportional to the width of the roads and the radius of their bends. Experiments revealed that the drivers of loaded vehicles who drove on lower-grade roads were under higher stress. Muscle load of drivers a loaded timber truck with a trailer was more difficult on roads of lower grades than on roads of grade I by 41.3%. Driving a timber truck is 21.9% more difficult on lower grade roads than on grade I roads. For preventive health and safety reasons, it is optimal to alternate trucking with a different type of work, thus minimizing the chance of occurrence of health disabilities.

“…Elsewhere, Zużewicz et al used heartbeats and electromyography (EMG) signals to study the physical responses of car drivers. Their results showed that EMG signal amplitude is very sensitive to such responses [ 14 ]. The median frequencies of EMG signals are often adopted as a key indicator of muscle fatigue.…”

Current sign-in methods of patrolling security guards mainly comprise signature, image identification, and fingerprint identification; notably, none of these methods indicate the physical and mental conditions of such guards. In particular, when patrolling security guards perform their duties consecutively for a long period of time, adequate attention should be directed toward their levels of mental fatigue. When a handwriting sign-in system is adopted, security guards may not record their sign-in time accurately, or they may fake signatures during long shifts. In addition, image identification systems cannot comprehensively reflect the physical and mental statuses of on-duty security guards, particularly their levels of fatigue. Monitor fatigue in patrolling security guards is important to avoid burnout and stress in the workplace. Therefore, in this study, a patrolling sign-in system that integrates physiological signals and images was designed. A thermometer, hand dynamometer, and electromyography sensor were combined to measure physiological signals. Results showed that hand grip strength and the median frequency of electromyography signals gradually reduced when muscle fatigue occurred. The system determined whether a security guard had signed in punctually and whether this person should stay on duty. Overall, this system was verified to operate effectively, and it is therefore applicable for monitoring the sign-in of patrolling security guards who work long shifts. This case series study proposed a conceptual prototype of the system; large-scale testing should be performed in subsequent research.
