Among the external physical factors that require attention during the process of projecting maglev transport, the key factor is the protection of staff and passengers from electromagnetic fields and mechanical accelerations that can cause extreme states in biochemical and physiological systems of living organisms. Objective: creation of tools, methods and recommendation systems, allowing to objectify the assessment of collective and individual security of the human beings being under the influence of maglev transport; assess the maximum allowable parameters. Methods: The most efficient way to achieve this goal is to use the methodology of polysystemic predictive diagnostics that allows to dynamically track in the degree of balance in regulative system of homeostasis which is a determining factor of individual adaptogenesis. In accordance with the laws of biomechanics, biomagnetism and stress theory, the impact of these adverse factors is causing resistive and adaptive restoration physiological responses at the same time, which subsequently, with the continuation of action and increase of dose and load, modify and lead to extreme and critical (pathological) states in human organism. From the literature on Biomagnetism, it follows that even weak magnetic fields can provide highly efficient action, and after organism being exposed to inductive magnetic fields of various intensity one-sided physiological shifts were observed. Organism's reactions to acceleration show similar behavior. The practical significance of the work lies in the fact that the study will specify hygiene requirements in absolute values and duration of adverse factors on the railways. Exceeding the exposure dose exposure on these indicators can cause irreversible negative condition of the body. However, due to the emergence of a fundamentally new transport technology, existing concepts require refinement and updating.

Adolescent suse internet via several devices to gather information or communicate. Sleep, as a key factor of adolescents’ development, contributes to their physical and mental health. Over the past decades insufficient sleep among adolescents has been wide spread, and one of its attributing factors is the increased availability of technology. This review aims to investigate the body of evidence regarding the impact of problematic internet use on adolescent sleep. Extensive search of databases was performed according to PRISMA guidelines for studies published within the last decade, regarding subjects aged 10–19. The final step of the search yielded 12 original studies. The quality of extracted data was evaluated with the AXIS tool, in order to estimate the risk of bias. All studies showed a negative correlation between adolescent sleep and problematic internet use. It was found to affect sleep quality and quantity and provoke insomnia symptoms. Interestingly, adolescent’s sex, parental educational level, type of family and use for leisure or academic reasons appeared as affecting factors of the problematic internet use-sleep relationship. Problematic internet use has several effects on adolescents’ sleep. Results of relevant studies should be embedded in educational interventions addressed to adolescents as well as parents, to eliminate the negative outcomes of problematic internet use on sleep and adolescence’s health in general.

Introduction. At present, the patterns of changes in the levels of biomarkers and the relationship of changes in their values with the pathogenesis of diseases caused by the impact of adverse factors of labour activity are not sufficiently studied. The most unresolved issues are the choice of informative laboratory indicators and diagnostic test systems in investigating the impact of physical factors on the working environment (vibration and physical overload) neurohumoral regulation: pituitary-adrenal pituitary-thyroid, pituitary-gonadal system and hormonal indicators of carbohydrate metabolism. The aim of the study was to determine diagnostic hormonal markers and integral indices to identify early changes in the neurohumoral status in the body of workers under the influence of working environment factors. Materials and methods. 330 workers of mining and machine-building enterprises were examined. Of these, 128 people with vibration disease, 45 people - with lumbosacral radiculopathy, combined pathology (vibration disease and lumbosacral radiculopathy) was detected in 60 persons. The preclinical stage (initial signs of diseases) was noted in 97 workers. Laboratory studies included hormones and integral indices of the pituitary-adrenal, pituitary-thyroid, pituitary-gonadal system, carbohydrate metabolism. To select the diagnostic significance of laboratory biomarkers, diagnostic sensitivity, prenosological value, pathognomonicity, direction, severity, and selectivity of changes in biomarker levels were evaluated. Results. The combined effect of vibration and physical overload on the body of workers was found to have a unidirectional and systemic impact on the levels of hormones of the pituitary-adrenal, pituitary-thyroid and pituitary-gonadal systems, increases insulin resistance. The severity of changes in neurohumoral regulation indicators depends on the nature and severity of the occupational neurological disease. The highest diagnostic sensitivity (Df = 72-74%) in vibration disease and its combination with lumbosacral radiculopathy was obtained for pituitary-gonadal hormones and indicators of insulin resistance. The lowest values of Dh are typical for the hormones of the pituitary-thyroid system (no more than 14%). To identify early changes in neurohumoral regulation in the body under the influence of vibration and physical exertion, it is most informative to determine the concentration of total testosterone, luteinizing hormone and insulin, as well as the integral pituitary-adrenal index, insulin resistance indices. To identify hidden disorders of the pituitary-thyroid system, the definition of the essential thyroid index can be used. Discussion. The results obtained allowed us to assess the nature of changes in the levels of hormones of the pituitary-adrenal, pituitary-thyroid and pituitary-gonadal systems and carbohydrate metabolism and to propose informative laboratory biomarkers reflecting early changes in neurohumoral regulation under the influence of physical factors of the working environment. Conclusions. To identify early changes in neurohumoral regulation in the body of workers under the influence of vibration and physical exertion, the most informative is the determination of the concentration of total testosterone, luteinizing hormone and insulin, the integral pituitary-adrenal index, and insulin resistance indices. To identify hidden disorders of the pituitary-thyroid system, the definition of the integral thyroid index can be used.

And Oxidative Stress

Healthy lifestyle and diet are associated with significant reduction in risk of obesity, type 2 diabetes, and cardiovascular diseases. Oxidative stress and the imbalance between prooxidants and antioxidants are linked to cardiovascular and metabolic diseases. Changes in antioxidant capacity of the body may lead to oxidative stress and vascular dysfunction. Diet is an important source of antioxidants, while exercise offers many health benefits as well. Recent findings have evidenced that diet and physical factors are correlated to oxidative stress. Diet and physical factors have debatable roles in modulating oxidative stress and effects on the endothelium. Since endothelium and oxidative stress play critical roles in cardiovascular and metabolic diseases, dietary and physical factors could have significant implications on prevention of the diseases. This review is aimed at summarizing the current knowledge on the impact of diet manipulation and physical factors on endothelium and oxidative stress, focusing on cardiovascular and metabolic diseases. We discuss the friend-and-foe role of dietary modification (including different diet styles, calorie restriction, and nutrient supplementation) on endothelium and oxidative stress, as well as the potential benefits and concerns of physical activity and exercise on endothelium and oxidative stress. A fine balance between oxidative stress and antioxidants is important for normal functions in the cells and interfering with this balance may lead to unfavorable effects. Further studies are needed to identify the best diet composition and exercise intensity.

Abstract Background and aims: The aim of the current study was to assess the impact of environmental factors; food, socio-economic, and physical activity, on a group of obese children living in Ain-Defla (Center Algeria) and Sidi-Bel-Abbes (West Algeria). Material and methods: The protocol was carried out on a cohort of 125 school children aged of 5 to 11 years, including 64 boys and 61 girls, and 139 school children, including 93 boys and 46 girls in Ain Defla and Sidi-Bel-Abbes respectively. Concerning the classification of obesity and overweight, we referred to the International Obesity Task Force and the French References' curves. Results: Regarding dietary intake our results showed that 34% of students from both regions took their breakfast, compared to 66% who did not take. Furthermore, 73% of students skipped at least one meal, however 23% respected meals frequency i.e. 4 meals a day. Regarding socio-economic factors and physical activity, our findings showed that obesity rates were high (36%) among children whose fathers are workers. However, for mothers who are housewives, obesity increases among their children (88%). The relationship was reversed between the parents' education level and the Body Mass Index. We found an opposite relationship between Body Mass Index and physical activity, and investigated children use screen devices for long time periods. Conclusions: Our study showed a positive relationship between obesity and overweight and environmental factors.

The Impact

Seasonal affective illness is seen as part of the seasonality of affective illness, not as a separate disease. All human beings are sensitive to light; the impact of light is hardwired in neuroanatomy. The body has intricate circadian rhythms that are regulated by the interaction of light with this neuroanatomy. Thus, everyone is affected by light, or its absence. Manic and depressive states, when part of the disease of manic-depressive illness, can have a seasonal pattern, with depression more prevalent in the fall/winter and mania in the spring/summer. The high prevalence of suicide in the spring likely relates to mixed manic states. Treatment with light boxes can be helpful symptomatically. Available studies are summarized. Importantly, light precautions, which involve behavioral interventions to increase or decrease light exposure, can prevent seasonal mood episodes.

Rehabilitation of patients with cardiovascular diseases is one of the most pressing problems in cardiological practice. Considering that cardiovascular pathology is the main cause of death and disability of the population of the most creative and working age, the approach to rehabilitation of this cohort of the population remains very relevant. We analyzed the main means of rehabilitation of patients with diseases of the cardiovascular system, which are used in modern times and justified a non-medical approach in the method of rehabilitation. We defined theoretical justification and development of technology of intermittent normobaric hypoxic low-intensity training on treadmil for cardioreabilitation of patients suffering myocardial infarction as the purpose of the study. The study examined the effect of intermittent normobaric hypoxic low-intensity training on treadmill on the body of patients who suffered myocardial infarction by the indicators of cardiovascular system, psychophysiological status. We noted our authors' method of cardioreabilitation during the experiment, the high clinical and practical significance. The method of normobaric hypoxic low intensity training on treadmill can be useful for optimisation of functional state of human organism, carrying out preventive and therapeutic measures, as well as rehabilitation of patients of general and cardiological profile.

Introduction. Regular physical load determines increase in functional capability of cardiovascular system. On the other hand, the cardiovascular system often appears as a conditional factor, which restricts organism adaptive abilities and limits general organism adaptation to the load. During physical load, not only cardiovascular system is activated, but also complex changes take place in the whole body. Therefore, with the aim to evaluate the functions of various systems, interrelation between them and systemic response of the body to physical load, a complex research on distinctive features of not only functional indices of the cardiovascular system, but also parameters reflecting interrelationship among functional systems of the body and speed of their changes is carried out. The goal of such complex research is the evaluation of adaptive and reserve capabilities of the athlete’s body and individualization and optimization of physical load. The aim of this study was to evaluate the speed of changes of parameters that characterize the functional condition of human organism of children and adolescents athletes and non-athletes controls. Materials and methods. One hundred sixty seven male athletes aged 14.8 (SD1.6, range 12-17 years) participating in basketball, rowing and cycling and168 healthy sedentary controls matched for age, sex and body surface area performed a graded exercise test (Mc. Master) on a cycle ergo-meter. 12 ECG standard derivations were synchronously recorded every second minute. During cycle ergo-meter integrated functional parameters, which could integrally and simple evaluate organism reaction to physical load, were assessed.Results. The present study demonstrates that before reaching the maximum of physical load, the speed of changes JT/RR in athletes and all functional parameters (HR, JT interval, RR interval, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse blood pressure (SBP-DBP), JT/RR ratio) in the control group decreased and in the last step of physical load has increased. That suggests that during intensive exercise training limits of physiological changes can be exceeded in athletes. Conclusions. Analysis of speed of changes in functional parameters during physical load can be applied for the evaluation of functional state of the human body and the cardiovascular system and aiming to optimize and individualize physical load in athletic children and adolescents.

This mini review examines the impact of tropical climate (TC) on motivational factors during aerobic performance and proposes the tracks of an integrative theoretical model to better understand the direct and indirect motivational mechanisms that can operate on athletic performances. TC is detrimental for aerobic performance and, although it clearly induces physiological constraints, these do not seem to be the only factors that explain the performance decline. Indeed, TC performance researchers have developed a theory of anticipation, which suggests that the brain commands a reduction in effort to protect the body from probable harm and heatstroke risk. The objective of this mini review is thus to examine the possibility that motivation may be a key factor in TC performance. The main psychological impacts of TC on aerobic performance are reviewed and an integrative theoretical model is presented that may help to better understand the mechanisms of motivation.

Ayurvedic science is being popularized worldwide. It has established history for the management of Bhagna in Sushruta Samhita. Ayurvedic philosophy is specific pertaining to the body constitution. The human body is composed of Dhatus. “Asthi” Dhatu is one of the main Dhatu in human body. “Asthi” is hard substance which remains even after most part of body has been decayed. Ayurvedic science has established history of trauma to Asthi (Asthibhagna). Ayurveda has aimed high for maintaining normal structure and function of deformed bones. It is high time to re-establish it by adopting proper research and methodology. The skeletal injuries are important incidences in human beings and they demand immediate management. The branch of science that deals with deformities of bones is known as Orthopedics, aimed for “maintenance of normal structure and function of deformed bones.” While bones are very strong they can break. Most often, breaks happen because the bone runs into a strong force, also repetitive force like from running can fracture a bone. High energy trauma result in bone fractures whether it is isolated fracture or dislocation. When a person goes through some form of trauma, as car accident or fall, the impact may break or fracture the bone. The bone fracture may be the result of high force impact or a result of certain medical conditions that weaken the bones such as Osteoporosis. Fracture is properly termed pathologic fracture but not trauma.
