Aim. The article aims to assess the body reserves of ski racers who develop local-regional muscle endurance (LRME), statokinetic and hypoxia resistance. Materials and methods. 15–16-year-old highly skilled ski-racers (I, II category, candidates for master of sports) with sports experience of 5–7 years (n = 12) were examined. The following equipment was used to assess athletic fitness and sports performance: T 2100 GE treadmill system, CardioSoft diagnostic system (USA), HYPOXICO Everest Summit II altitude generator (USA), Angio Scan-01 P pulse oximeter sensor (Russia). Statistical analysis was performed using the SPSS information processing package. Results. The effect of techniques for developing LRME and hypoxia resistance on sports performance has been established. A generalized ranking of competitive performance is constructed and a regression model is described that establishes the dependence of sports performance on morphofunctional and metabolic statuses. The key indicators of morphofunctional and metabolic statuses were compared in athletes who used the methods for developing LRME and hypoxia resistance. Criteria are established for successful performance in sports reserve training, promising cross-country skiers, the modeling of status indicators with well-established technologies while maintaining the functional and metabolic potential and the level of health. Conclusion. The results of the study showed the effectiveness of combined technologies in sports training and allowed to identify markers of functional and metabolic statuses. The proposed technologies allowed to enhance adaptation and identify status markers. This made it possible to improve performance in the conditions of LRME and statokinetic and hypoxia resistance. Forecasting sports results allows regulating athletic fitness and making timely corrections to ensure successful sports performance.

Introduction. To increase the effectiveness of social and hygienic monitoring of the health status of workers in harmful and/or dangerous occupation conditions by objectifying the analysis of the health status of workers and timely detection of premorbid forms of pathology, an informational medical advisory and diagnostic system is proposed that ensures the efficiency of using the previously developed methodological recommendations MR 2.2.9.0148-19 “Assessment of the risk of developing states of distress in workers in harmful working conditions”. Materials and methods. The design of the developed computer program is based on the principles of critical assessment of the employee’s health status; multiparametric characteristics of the functional reserves of the body; unity of the information base; the possibility of dynamic monitoring of the health status of employees; automation of data storage and analysis; protection of personal data. Results. The method used by the information system is based on a comprehensive assessment of the functional reserves of the body, correlated by the degree of adaptive stress, including the ranking of the employee health status according to the group of dispensary records, the indicator of adaptive compliance and the level of adaptive immunity. To facilitate the operator’s information support system integrated the List of harmful and (or) hazardous occupation factors, the presence of which is a mandatory preliminary and periodic medical examinations (surveys) and reference weight values, heart rate and blood pressure corresponding to the physiological norm concerning gender and age of the employee. Conclusion. The proposed information system can be used during periodic medical examinations to form risk groups for the development of occupational and production-related morbidity, as well as to assess the effectiveness of hygienic and therapeutic and preventive measures aimed at improving the health of workers in harmful occupation conditions.

Nitrate Supplementation

Nitrate supplementation is an effective, evidence-based dietary strategy for enhancing sports performance. The effects of dietary nitrate seem to be mediated by the ability of oral bacteria to reduce nitrate to nitrite, thus increasing the levels of nitrite in circulation that may be further reduced to nitric oxide in the body. The gut microbiota has been recently implicated in sports performance by improving muscle function through the supply of certain metabolites. In this line, skeletal muscle can also serve as a reservoir of nitrate. Here we review the bacteria of the oral cavity involved in the reduction of nitrate to nitrite and the possible changes induced by nitrite and their effect on gastrointestinal balance and gut microbiota homeostasis. The potential role of gut bacteria in the reduction of nitrate to nitrite and as a supplier of the signaling molecule nitric oxide to the blood circulation and muscles has not been explored in any great detail.

In recent years it has been conclusively shown how the position of the mouth in relation to the body affects the way of walking and standing. In particular, occlusion, the relationship between skull and jaw, swallowing and convergence of the eyes are in neuro-muscular relationship with the control and maintenance system of posture, integrating at different levels. This manuscript aims to be a summary of all the oral, occlusal and articular dysfunctions of TMJ with systemic and postural–muscular repercussions. Recent articles found in the literature that are taken into consideration and briefly analyzed represent an important starting point for these correlations, which are still unclear in the medical field. Posturology, occlusal and oral influences on posture, spine and muscular system are still much debated today. In the literature, there are articles concerning sports performance and dental occlusion or even the postural characteristics of adolescents or children in deciduous and mixed dentition. The temporomandibular joint, as the only joint of the skull, could therefore represent a site to pay particular attention to, and in some cases an ATM dysfunction could be a clue for the diagnosis of systemic pathologies, or it could be the repercussion.

The purpose was to identify the peculiarities of selected training and sport performance characteristics: 1. Training strategies, 2. the body sway and 3. mental fitness. Methods: we analysed the sport performance and training characteristics and applied interviews with elite and Lithuanian shooters. The body sway was studied applying the method of static posturography. The subjects were standing in four postures. Mental fitness of the shooters was evaluated 30 min before the start using CSAI–2 methodology and adapted SCAT methodology. The shooters were divided into two groups according to their sports performance: the high and the moderate mastery groups. Statistical analyses was made applying the SPSS 11.0 statistical package. Results: 1. The Lithuanian women pistol shooters’ mean age of the first three place winners corresponded to that of the elite athletes, however the sports results (p < 0.001) were significantly lower. We indicated the following reasons: they trained less than the elite shooters, their specific training was inappropriate (p < 0.001), their mental fitness and competition experience were inappropriate (p < 0.001). 2. The trajectory of the COP in a specific posture (legs at shoulder length, arms down; posture without the pistol; posture with the pistol) was significantly (p < 0.05) different (Fig. 1, Masalskytė et al., 2002) between high and moderate mastery shooters but not in general posture (folded legs and arms down). The results suggested developing shooters’ posture from the very beginning of training. 3. The Lithuanian shooters’ level of anxiety before the starts showed the importance of the duration of exercise and competition experience because the difference between their indices and those of elite shooters was significantly less (p < 0.001). Conclusions: On the basis of sport performance as a multidimensional construct which requires to select the main factors of athlete trainability we conclude that Lithuanian pistol and rifle shooters need a training programme that improves posture stability; they should increase their international competitive experience and have to monitor sport fitness in order to manage psychological stress, and model a further training programme. Social conditions might be the main problem of the Lithuanian shooters to terminate their sport career too early.Keywords: pistol, rifle, shooters’ training, sport performance.
