Electromyographic Analysis of Deep Trunk Muscles During Sports Activities

Recent evidence indicates that turning difficulty may correlate with trunk control; however, surface electromyography has not been used to explore trunk muscle activity during turning after stroke. This study investigated trunk muscle activation patterns during standing turns in healthy controls (HCs) and patients with stroke with turning difficulty (TD) and no TD (NTD). The participants with stroke were divided into two groups according to the 180° turning duration and number of steps to determine the presence of TD. The activation patterns of the bilateral external oblique and erector spinae muscles of all the participants were recorded during 90° standing turns. A total of 14 HCs, 14 patients with TD, and 14 patients with NTD were recruited. The duration and number of steps in the turning of the TD group were greater than those of the HCs, independent of the turning direction. However, the NTD group had a significantly longer turning duration than did the HC group only toward the paretic side. Their performance was similar when turning toward the non-paretic side; this result is consistent with electromyographic findings. Both TD and NTD groups demonstrated increased amplitudes of trunk muscles compared with the HC groups. Their trunk muscles failed to maintain consistent amplitudes during the entire movement of standing turns in the direction that they required more time or steps to turn toward (i.e., turning in either direction for the TD group and turning toward the paretic side for the NTD group). Patients with stroke had augmented activation of trunk muscles during turning. When patients with TD turned toward either direction and when patients with NTD turned toward the paretic side, the flexible adaptations and selective actions of trunk muscles observed in the HCs were absent. Such distinct activation patterns during turning may contribute to poor turning performance and elevate the risk of falling. Our findings provide insights into the contribution and importance of trunk muscles during turning and the association with TD after stroke. These findings may help guide the development of more effective rehabilitation therapies that target specific muscles for those with TD.

Timely Treatment

Introduction. Modern sports places high demands on the functional systems of the body at all stages of the training and competitive processes. High loads create signifi cant background for the occurrence of musculoskeletal diseases, among which the myofascial syndrome (MFS) holds the leading position. MFS negatively affects the functional readiness of the sportsman′s body and is a risk factor for injuries of the musculoskeletal system. In this regard, timely treatment of MFS is important. It creates the conditions for the improvement of sports achievements, for health maintenance and sports longevity. Treatment of patients with MFS should include methods that normalize trophism and muscle tone. Given the problem of doping, the use of non-drug methods, including osteopathy, is preferable. The goal of research — to develop a system of monitoring and osteopathic correction of myofascial disorders (MFD) and to introduce it into the practice of medical and biological support for sportsmen of different categories and levels during the annual training process.Materials and methods. 93 sportsmen (45 women and 48 men), mean age 22,1±1,1 years, representing diffe rent sports were examined. The essence of the proposed system is regular clinical and electroneurophysiological monitoring of the body condition and preventive correction of myofascial disorders in order to exclude their infl uence on the success of sports activities.Results. It was established that the proposed system of monitoring and osteopathic correction led to a signifi cant reduction in clinical and electroneurophysiological manifestations both in local and in extensive forms of myofascial disorders, which allowed to maintain the optimal functional readiness of sportsmen throughout the entire annual training cycle.Conclusion. The system of monitoring and correction of MFS with the use of osteopathic treatment can be one of the elements of medical and biological support for sportsmen during the annual training process.

Summary Purpose: to determine the relationship between achievement motivation and the attitudes of schoolchildren of 11-17 years old and students of 18-21 years old to independent sports and passing control standards in the discipline \”Physical Education\”. Material: 1576 schoolchildren (boys n = 780 and girls n = 796) of comprehensive schools of Belgorod, Stary Oskol, Stroitel and Shebekino (Belgorod region, Russian Federation) and 246 students (men n = 127) were surveyed. and women n = 119) Belgorod State Technological University named after V.G. Shukhov (Belgorod, Russian Federation). The questionnaire consisted of three blocks of questions: the 1st block of questions - questions aimed at determining the age, sex, place of study of the respondent; 2nd block of questions - 8 questions, allowing to assess the attitude of the respondent to independent sports activities and the desire to take control standards of the discipline Y’Physical Education\”; 3rd block of questions is a test of 20 questions, developed by A.A. Rean, to assess the motivation to achieve success and avoid failures. Results: the motivation for avoiding failures was diagnosed in 5% male students and 10% female students. A direct correlation between achievement motivation and the attitude of schoolchildren and students towards independent sports activities and passing control standards has been revealed. Conclusions: there are no differences in the correlation between the relationship between achievement motivation and attitudes toward independent sports by gender. Schoolchildren and students with motivation to achieve regular self-exercise. Schoolchildren and students with a pronounced motivation for avoiding failures prefer a passive way of life. They do not want to pass standards on the discipline \”Physical Education\” and do not go in for sports on their own.

Abstract The paper presents the results of a determinative study regarding the health profits obtained by the citizens of Caras-Severin County involved in the practice of leisure sport through the program sport for all offered. The aspect highlighted is that sport, for all, has beneficial effects on health being contained by all the components of life quality. The aim of the paper is to prove that issuing leisure time sports programs according to the needs of the client population increases the number of practitioners of sport and implicitly it contributes to the maintenance and improvement of the health state. In order to pursue health profits, the physical and psychic wellbeing of the participants in the sports programs, the observation method, the tests method and the method of recording the health coefficients on a protocol basis were used. The observation was achieved on a sample of 217 subjects which were initially tested, at the beginning of the programs and at the end of the research period. The conclusion was that the main component elements of life quality which can be ameliorated by free time sport activities are: health state; the biologic potential through the evaluation of the anthropometric, functional and physiological coefficients; motor skills; psycho-social relations and social integration. The health state, the biologic potential, motor skills, socialization can be considered dependent variables and through sports activities for all and through the implemented programs a strategic project of continuous development can be elaborated. Leisure sports activities ameliorate life quality of different categories of citizens and social groups.
