Aim. The article aims to assess the psychophysiological characteristics of skilled athletes in combat sports (boxing, freestyle wrestling, judo). Materials and methods. 18–23-year-old skilled combat athletes were examined. All athletes were divided into the following groups: the first group - female athletes (n = 15); the second group - male athletes (n = 17); the third and fourth groups - control groups consisted of males and females of the same age and not involved in sports (15 people each). The following methods were used: a pulse measurement, psychological tests, self-assessment of the psychoemotional status, electroencephalography, cardiointervalography with the calculation of statistical indicators of heart rate. Examinations were performed before and after the relaxation exercise, which was a three-minute concentration of attention at a specific point on the body. Results. The results revealed that female athletes had lower indicators of psychoemotional status than males but higher than untrained females. The indicators of psychoemotional stress were lower in female athletes than in male athletes and untrained women. For example, the indicator of personal anxiety in female athletes was 41.0 ± 1.8 versus 47.2 ± 2.5 in untrained women (P < 0.05). In female athletes, heart rate, the amplitude of the mode and voltage index (77.15 ± 2.05) in the structure of heart rate were slightly higher than in males (73.10 ± ± 1.07), which indicated greater functional stress of the heart. Relaxation led to favorable changes in EEG indicators and decreased functional stress of the heart in all subjects. Conclusion. It is recommended to extend the terms of sports training in female combat athletes to ensure a smooth transition to sports specialization and reduce injuries.

ABSTRACT Balanced nutrition is very important for athletes’ health and competition performance, and balanced nutrition has become a hot topic in the sports industry. In this study, 30s anaerobic work test and maximal oxygen uptake test were used to test anaerobic exercise ability and aerobic exercise ability, respectively. Four groups were set up in the two test methods, and the corresponding functional test indexes, heart rate recovery index and blood lactic acid recovery value were determined. The anaerobic capacity test showed that the maximum power of male athletes in the experimental group had significant statistical difference before and after dietary balance management, and the fatigue index of female athletes in the experimental group had a significant downward trend. Five minutes and nine minutes after exercise, the blood lactic acid value of males in the experimental group was lower than before balanced nutrition. The aerobic capacity test showed that the exhaustion time of male athletes in the experimental group was significantly different before and after balanced nutrition. After the balanced nutrition, the blood lactic acid value of male athletes in the experimental group was lower than before the management immediately and nine minutes after exercise, and the heart rate value of the male athletes in the experimental group was far lower than before the management.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

Background: Caffeine consumption may adversely affect the performance of athletes in some sports. Aim: The aim of this study was to investigate the effects of caffeine drink consumed before competitions by air pistol athletes on their heart rate, trigger squeeze times and shooting scores. Methods: : In the study, caffeinated and caffeine-free measurements were applied on the same athletes. Following the evaluation, a total of 20 elite athletes, including 10 women with a mean age of 23.6±4.7 and 10 men with a mean age of 25.9±4.8 who had at least 2 years sports history, participated voluntarily in the study. The study was planned as a single blind. All athletes shot 10 times before both measurements. By random method, the athletes consumed Coffee with 3mg/kg caffeine or decaf coffee before the measurement. After 1 week, the same athletes were given coffee which was not given in the previous measurement before the measurement. A total of 80 shots were fired at 15, 30 and 60 minutes after both measurements. Following the evaluation, heart rates, trigger squeeze times and shooting scores of the athletes were recorded. Wilcoxon test to compare the differences between the measurements at two different times on the same group and Mann-Whitney U test to examine the differences in independent groups were used. Results: When the differences between the measurements of all male and female athletes were examined, it was found that there was an increase in their heart rate and trigger squeeze times 15, 30 and 60 minutes after caffeinated coffee consumption, and this difference was statistically significant (p<0.05). Besides there was a significant decrease in 15, 30 and 60 minute shooting scores of female athletes, and 15 and 30 minute shooting scores of male athletes (p<0.05). Conclusion: As a result of the study, it was observed that the use of caffeine had a negative effect on the performance of air pistol athletes. Therefore, it can be said that people interested in air pistol discipline should not consume coffee or caffeine-containing beverages within 1-2 hours before the competition, if they consume, their heart rate will increase and their aiming during shooting will be more difficult and trigger-squeezing times will be extended.

A study at 5 C was made of body temperature and heart rate after a standard dose of sodium pentobarbital in normal, thyroidectomized, and hypermetabolic rats before and after subjection to 5 C for 46 hr. It was found that after subjection to cold in the normal rats, the body temperature and heart rate in some animals had more ability to recover after the barbiturate than in rats without previous exposure to cold. There was no ability to recover in the thyroidectomized animals either before or after subjection to cold. Most of the normal and thyroidectomized rats either with or without previous exposure to cold given sodium 3,3',5-l-triiodothyronine (T-3) had recoveries after the barbiturate. Some rats given T-3 and subjected to cold had a primary fall in temperature and heart rate that was followed by recovery and then a secondary fall.

Aim. The article deals with studying the features of psychophysiological adaptation to physical load and the functional status of the cardiovascular system in badminton players. Materials and methods. The study was conducted in the premises of Dostoevsky Omsk State University during badminton training activities as a part of Omsk Higher Educational Establishments Spartakiadpreparation in September 2016 – May 2018. Fifteen students aged 18–19 years participated in the study on a voluntary basis. The study was conducted using the electronic surveys placed onhttps://onlinetestpad.com: the Spielberger state-trait anxiety inventory and the Well-Being, Activity, Mood test. To establish the maximum anaerobic capacity of the body, the Margaria testwas used. A Zeugner’s polychromatic rapid test was used for establishing the emotional background. Results. The analysis of the results obtained revealed that the highest heart rate values were registered during a long badminton rally and reached 190 bpm. During pauses heart rate decreased to 160 bpm. A badminton rally of 4–6 seconds allowed maintaining the heart rate at 160 bpm.If followed by pauses heart rate decreased to 130 bpm. Assessing the mechanisms of psychophysiological adaptation and studying the subjective characteristics of situational and personal anxiety, well-being, performance and emotional background before and after training allow identifying athletes with different adaptation capacities and increasing their physical performance. Conclusion. The analysis of the results obtained demonstrated changes in psychophysiological adaptation and the functional status of the cardiovascular system. It was also revealed that physical load provoked stress in the mechanisms of psychophysiological adaptation.

Using Data

Mobile measures of human circadian rhythms (CR) are needed in the age of chronotherapy. Two wearable measures of CR have recently been validated: one that uses heart rate to extract circadian rhythms that originate in the sinoatrial node of the heart, and another that uses activity to predict the laboratory gold standard and central circadian pacemaker marker, dim light melatonin onset (DLMO). We first find that the heart rate markers of normal real-world individuals align with laboratory DLMO measurements when we account for heart rate phase error. Next, we expand upon previous work that has examined sleep patterns or chronotypes during the COVID-19 lockdown by studying the effects of social distancing on circadian rhythms. In particular, using data collected from the Social Rhythms app, a mobile application where individuals upload their wearable data and receive reports on their circadian rhythms, we compared the two circadian phase estimates before and after social distancing. Interestingly, we found that the lockdown had different effects on the two ambulatory measurements. Before the lockdown, the two measures aligned, as predicted by laboratory data. After the lockdown, when circadian timekeeping signals were blunted, these measures diverged in 70% of subjects (with circadian rhythms in heart rate, or CRHR, becoming delayed). Thus, while either approach can measure circadian rhythms, both are needed to understand internal desynchrony. We also argue that interventions may be needed in future lockdowns to better align separate circadian rhythms in the body.

SummaryStudy aim: The body structure can play a determining role in the achievement of top judo performance, and it seems to influence the type of techniques applied. The aim of this study is to determine the somatotypes in male and female national level judokas across weight categories in order to observe possible differences among athletes.Material and methods: A total of 61 male judokas (23.2 ± 2.7 years old) and 37 female judokas (22.3 ± 3.3 years old) participated in this study. Anthropometric variables were used to calculate somatotypes. Somatotypes were determined according to the Heath-Carter method. Analysis of variance and Tukey’s post hoc test were used to determine differences between weight categories and obtained effect sizes (η2) were presented as well.Results: Somatotype differences among weight categories in male and female judokas were observed. Generally, all categories could be classified in three somatotypes in male and female athletes.Conclusions: The lightest categories were recognized as mesomorphic ectomorphs in females with an exception in the –48 kg category, and ectomorphic mesomorphs in male athletes. The middle ones had the endomorphic mesomorph somatotype and the heaviest athletes presented somewhat more extreme cases of endomorphic mesomorphs, both in male and female judokas. According to the results obtained, judokas have a specific body composition in different weight categories. Therefore, coaches could create a specific training programme for athletes who belong to different somatotypes.

Aim. To determine the effectiveness of the specific loading testing use in assessing the athletes’ physical performance. Material and methods. We present a post-hoc analysis of data from specific and nonspecific loading testing (bicycle ergometer, treadmill, rowing ergometer, and ski treadmill) of 23 oarsmen athletes (13 male (mean age 25.85±0.88 years) and 10 female (mean age 22.90±1.20 years); 125 track and field athletes (75 male athletes (mean age 24.74±0.91) and 50 female athletes (mean age 23.81±1.35)), 38 ski athletes (22 male athletes (mean age 21.3±2.4) and 16 female athletes (mean age 19.6±1.8)). Results and discussion. When assessing the physical performance of track and field athletes of various positions using a bicycle ergometer and a treadmill, the maximum oxygen consumption (MOC) parameter for throwers and jumpers was in the range of 29-55 ml/min/kg (it is more appropriate to use a statoergometer), for runners – 39-75 ml/min/kg (testing on a treadmill is preferable). The greatest efficiency and physiological validity was obtained by load testing using a rowing ergometer for rowing athletes and a ski roller treadmill for athletes of ski sports (the ratio of heart rate at the anaerobic metabolism threshold level to the heart rate “on failure” is ~ 97%). With bicycle ergometry, low values of MOC were obtained in athletes training for endurance, and, including on the treadmill, in athletes with the main strength load and implies the work of the muscles of the upper shoulder girdle and back. The functional and reserve capabilities of the athlete are not reflected in the data obtained that makes impossible to judge the level of his/her functional readiness. Conclusion. Sports medicine technologies reflecting the dynamic characteristics of athletes’ physical performance should be evaluated from the point of view of informativeness and efficiency of their application depending on the type of sport. Conclusion about the effectiveness of sports medicine technologies should be made considering the results of the functional and physical performance testing under the exertion, specific to a particular sport.

Introduction: Fibromyalgia syndrome is characterized by musculo-skeletal pain. Heart rate variability (HRV) is a versatile and promising non-invasive marker of the autonomous nervous system. Micro-physiotherapy involves manual physiotherapy that seeks to identify the primary cause of a disease or symptom and to stimulate self-healing, in which the body recognizes the aggressor (antigen) and begins the elimination process, through cellular and tissue reprogramming. Method: The sample was composed of 15 individuals, aged between 35 and 40 years, with fibromyalgia. The Nerve Express method was used to assess the variability of the heart rate. Two sessions of micro-physiotherapy were conducted using global methods, with an interval of 45 days between sessions. Results: Based on the HRV results, the high frequency band was confirmed at p=0.203, with the low frequency recording a statistically significant value of p=0.001, thereby demonstrating sympathetic activity. Upon comparison of the mean heartbeat before and after treatment, a value of p=0.0006 was obtained. A value of p=0.049 was recorded in the analysis of the median R-R interval values. Conclusion: The use of micro-physiotherapy as a treatment method for fibromyalgia effectively improved the lives of patients by promoting sympathicotonia.
