Heart rate variability in university students engaged in competitive sports at the beginning of a training season

Objective: to study heart rate variability in university students engaged in competitive sports at the beginning of a training season. Materials and Methods: the study summarizes the results of 141 participants. The study group consisted of 61 athletes (22.7±1.3 years), 31 men (22.3±1.3 years) and 30 women (23.1±2.1 years). The control group included 80 students not involved in sports (23.6±1.5 years), 34 men (23.7±1.5 years) and 46 women (23.6±1.5 years). Heart rate variability was assessed by a cardiointervalogramm registration in the background recording of rest for 5 minutes, as well as during an active orthostatic test. A spectral analysis of heart rate wave structure included registration HF, LF, VLF-components, LF/HF ration, and the total power of all waves – TP; complex indices were determined, namely the index of vegetative balance (AMO/SD index) and C30:15 coefficient. Results: we found higher level total spectrum power, parasympathetic activity and reactivity regulation in the study group. We revealed higher spectral indices, as well as C30:15 during active orthostatic tests in the group of athletes. HRV indices of male athletes are higher, both at rest and in orthostasis. HRV indices of female athletes significantly differed only in orthostasis, demonstrating a higher level of regulation. Conclusions: at the beginning of a training season, we found high level of regulatory indices in the functional state of competitive athletes, both male and female. A variety of significant differences in HRV in the studied groups can be used for a dynamic monitoring of changes in regulatory processes during the training cycle

Volitional self-regulation and emotional burnout of professional sambo-athletes who suffered from sports injuries

Objective: to study the level of volitional self-regulation and emotional burnout in male sambo-athletes who underwent sports injuries of various degrees of severity. Materials and methods: 60 male sambo-athletes were examined. They were divided into 3 groups of 20 people in each group based on types of sports injuries. Results: significantly (p=0.001) lower level of volitional self-regulation was found in the third group who underwent more injuries (total scale: Q1=6,0; Me=8,0; Q3=10,0; «perseverance»: Q1=5,0; Me=5,5; Q3=8,0; «self-control»: Q1=4,0; Me=4,5; Q3=5,0). More pronounced emotional burnout occured in athletes who had more injuries (Q1=64,5; Me=69,0; Q3=71,0; p=0,001). Inadequate emotional response and emotional and moral disorientation was leveled down with aggravation of the severity of injuries (Q1=25,0; Me=44,0; Q3=61,0; p=0,039). Adaptation systems strain is manifested by a marked emotional exhaustion and decrease in volitional self-regulation with an increase in the number of injuries. Conclusions: if incidence and severity of injuries increases in sambo-athletes the level of volitional self-regulation reduces and emotional burnout occurs, which is characterized by the stress of the system of psychological adaptation

Effectiveness of resort the drug Miidronate in order to the level of improve mental performance and to correct psychosomatic status of youth ice hockey league players

The relevance of the issue of scientific research is due to the high prevalence of cognitive impairment of the population, the high prevalence of MP among middle-aged people in the city of Perm. Studying the dynamics of cognitive functions and mental performance of athletes will allow to prevent development of the syndrome of overtraining and decrease of athletic performance. Materials and Methods: The study involved 25 professional athletes of the youth ice hockey league of the sports club "Molof, at the city of Perm. All participants of the study were male, the average age of the athletes was 18,52 ± 1,23 years. All athletes had a general clinical research, diagnosis of mental and emotional status, determining the level of mental health with the help of a battery of psychophysiological tests. Results: The average index increase was recorded after interfering, visual memory, volume, attention switch, mental productivity and interest.Актуальность темы научного исследования обусловлена высокой распространенностью когнитивных нарушений в популяции, высокой распространенность умеренных когнитивных расстройств у лиц зрелого возраста г. Перми. Изучение динамики когнитивных функций и умственной работоспособности у спортсменов позволит предупредить развитие синдрома перетренированное™ и снижения спортивной работоспособности. В исследовании приняли участие 25 профессиональных спортсменов молодежной лиги по хоккею с шайбой спортивного клуба «Молот», город Пермь. Все участники исследования были мужского пола, средний возраст спортсменов -18,52+1,23 лет. Всем спортсменам проводилось общее клинического исследование, диагностика психоэмоционального статуса, определение уровня умственной работоспособности с помощью батареи психофизиологических тестов. Результаты: регистрировалось повышение среднего показателя памяти после интерферирующей, зрительной памяти, объема и переключения внимания, а также психической продуктивности и интереса
