Abstract: The objective of the elaboration was to assess the degree of physical load in direct start preparation (DSP) during preparations of disabled sitting volleyball players for the Polish championships.: Players of the “Start” Sports Club of the Disabled in Wroclaw who play sitting volleyball professionally participated in the study. The subjects of the study were men aged 17 to 53 (average age: 31.9); they have been playing sitting volleyball for 2.5 to 33 years. Twelve sitting volleyball players with various disabilities concerning uni- and bilateral amputation within the lower leg and thigh, with malformation and short lower limbs participated in the study.: The study involved assessment of the exercise capacity of sitting volleyball players during 7 training units in introductory and intensifying micro-cycles within DSP. Heart rate results at six moments (at the beginning, in the 10: Years of training significantly correlated with age of the participants. The participants were characterized by significantly lower resting heart rate in the intensifying micro-cycle than in the introductory microcycle which may result from adaptation of the body to physical effort. The largest differences in average heart rate values at the considered moments of training units in training micro-cycles within DSP were observed in the measurement of resting heat rate and final heart rate. Standard deviation in the introductory micro-cycle and the intensifying micro-cycle within DSP was growing in a linear manner, except for the peak heart rate index. Resting heart rate significantly impacted the value of heart rate during training units within DSP.Volleyball players participating in the study were characterized by significantly lower resting hear rate in the intensifying micro-cycle than in the introductory micro-cycle within DSP which may result from adaptation of the body to physical effort. The lowest percentage difference of the average heart rate value occurred in the assessment of final heart rate, while at the remaining moments of training units heart rate values reached the same percentage value. The course of regeneration in both compared micro-cycles (DSP) was similar and it did not vary significantly. Restoring the value of resting heart rate occurred after more than 15 minutes after training.

Abstract Objectives To examine the direction, strength and causality of the associations of resting heart rate (RHR) with cardiometabolic traits. Methods We assessed the strength of associations between measured RHR and cardiometabolic traits in 506,211 and 372,452 participants from China Kadoorie Biobank (CKB) and UK Biobank (UKB). Mendelian randomization (MR) analyses were used to make causal inferences in 99,228 and 371,508 participants from CKB and UKB, respectively. Results We identified significant, directionally-concordant observational associations between RHR and higher total cholesterol, triglycerides (TG), low-density lipoprotein, C-reactive protein (CRP), glucose, body mass index, waist-hip ratio (WHR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the Bonferroni correction. MR analyses showed that 10 beat/min higher genetically-predicted RHR were trans-ethnically associated with a higher DBP (beta 2.059 [95%CI 1.544, 2.574] mmHg in CKB; 2.037 [1.845, 2.229] mmHg in UKB), higher CRP (0.180 [0.057, 0.303] log mg/L in CKB; 0.154 [0.134, 0.174] log mg/L in UKB), higher TG (0.052 [-0.009, 0.113] log mmol/L in CKB; 0.020 [0.010, 0.030] log mmol/L in UKB) and higher WHR (0.218 [-0.033, 0.469] % in CKB; 0.225 [0.111, 0.339] % in UKB). In the opposite direction, higher genetically-predicted SBP, TG, glucose, WHR and lower high-density lipoprotein were associated with elevated RHR. Conclusion Our large-scale analyses provide causal evidence between RHR and cardiometabolic traits, highlighting the importance of monitoring heat rate as a means of alleviating the adverse effect of metabolic disorders.

Beer Consumption

Background and objectives: Beer consumed in moderation (330 mL/day for women and 660 mL/day for men, up to 5% alcohol) may have certain benefits for the human body, due to natural ingredients, but especially due to important sources of protein, fiber and antioxidants. According to specialized studies, beer consumed in moderation can have beneficial effects on the body. Materials and methods: The study was conducted on 50 subjects selected based on characteristics such as age, height, weight and not after exercising or doing physical activities. All research subjects benefited from two evaluations (initial and final), consisting of: physical examination, EKG examination, body hydration analysis, adipose tissue analysis, muscle tissue analysis, heart rate analysis and speed motor quality. These analyses were performed daily for a period of seven days, both for the initial and the final evaluation (a total of 14 days of assessments). Results: Between the two evaluations, subjects consumed 660 mL of beer with up to 5% alcohol daily (WHO recommended dose) for 30 days. The results obtained (at the initial and final evaluation) were inventoried and statistically processed using statistical programs. It was found that moderate beer consumption (660 mL of beer with up to 5% alcohol) daily for a period of 30 days can lead to an increase in body hydration, a decrease in adipose tissue as well as an increase in muscle mass. In addition, a decrease in heart rate was observed after physical activity (short running on 100 m), which leads us to a better adaptation of the body after intense physical effort. Discussion and conclusion: Moderate beer consumption (660 mL/day for men, up to 5% alcohol, WHO recommended dose) can have beneficial effects on body hydration, adipose and muscle tissue, and better adaptation of the body after intense physical effort.

Annotation. Appropriate cardiointervalographic parameters establishment, for highly skilled athletes of a particular sport, is relevant and can be used for diagnostic purposes and because of connection with the widespread prevalence of cardiovascular pathology. The purpose of the work was to construct regression models of the variations of the pulsometry in volleyball players of the mesomorphic somatotype, depending on the features of anthropometric indicators. The study involved 24 volleyball players with a high level of sportsmanship (from the first adult category to candidates for the master of sports), aged 17–21 years. We carried out anthropometric research by Bunak's method (1941), somatotypological - by the calculated modification of the Heath-Carter method (1990), determination of the component composition of the body weight by the method of Matejko (1992) and cardiointervalographic examination using a computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association [1996]. The following indicators of variation heart rate were determined: moda, moda amplitude, average minimum and maximum R-R intervals, and variation range. The mathematical models were constructed in the “STATISTICA 5.5” package for Windows using direct stepwise regression analysis. The article presents the results of regression analysis for determining the dependence of variation heart rate indicators in volleyball players of mesomorphic somatotype on the total complex of constitutional characteristics. Mathematical models for determination of individual proper cardiointervalographic parameters based on features of the external structure of the body of youth volleyball players of high level of sportsmanship. The analysis of constitutional predictors that determine the variability of indicators of variation heart rate in a group of volleyball players of mesomorphic somatotype has been performed.

Kinematics And Kinetics

Volleyball players often land on a single leg following a spike shot because of a shift in the center of gravity. This landing is one of the high-risk actions for non-contact ACL injury. The purpose of this study was to compare and analyze the discrete and temporal kinematics and kinetics associated with functional valgus collapse during volleyball in player landing phases during a single-leg landing and double-leg landing following a spike shot. Kinematics and kinetics data were collected (captured by a Vicon motion system and AMTI force plate, processed by Visual-3D software) during the single-leg and double-leg landing phases in 13 semi-professional male volleyball players. The landing phase was defined as initial ground contact (0% landing phase) to maximum knee flexion (100% landing phase). Statistical Parametric Mapping (SPM) analysis revealed that single-leg landing depicted a significantly greater knee abduction angle and hip adduction moment than double-leg landing during the 0%–68% landing phase (single-leg: 7°–16°, double-leg: 0°–9°, p < 0.001) and 18%–22% (single-leg: 0.62–0.91 Nm/kg, double-leg: 0.08–0.19 Nm/kg, p = 0.0063) landing phase, respectively. The traditional discrete analysis revealed that single-leg landing depicted a significantly greater peak knee internal rotation moment (single-leg: 1.46 ± 0.38 Nm/kg, double-leg: 0.79 ± 0.19 Nm/kg, p = 0.006) and peak hip internal rotation moment (single-leg: −2.20 ± 0.54 Nm/kg, double-leg: −0.88 ± 0.30 Nm/kg, p = 0.011) than double-leg landing. Most differences were within a time frame during the landing phase of 30–50 ms in which non-contact ACL injuries are considered to happen. These recorded time frames are consistent with biomechanical measures that are deemed dangerous. To reduce lower limb injury, a volleyball player should consciously swing the arms to influence the body to maintain a better-balanced state. Adjusting the landing mode of the lower limbs can achieve a good cushioning effect during landing following a spike shot.

Respiratory Rate (RR) is a vital sign representing air movement in and out of the body. Neglecting the respiratory rate can foresee the patient being at risk. The lack of portable device in a point of care unit, i.e. ambulances, can be a demanding task. In this study, the researchers developed a hardware device that can measure resting Heart Rate (HR) and RR from a custom pulse oximeter tethered to the Arduino board using signal processing to extract HR and Symlet Wavelet Transform to extract the RR. The derived HR and RR from a custom pulse oximeter is compared to a clinical-grade pulse oximeter and yielded an MSE of around 3.8. Moreover, results obtained from the custom pulse oximeter vs the reference are close and valid.

Objective: to describe the effect of music on pain of burn victims during the dressing change. Methods: applied, descriptive, exploratory and quantitative research held in a Burn Treatment Unit from October 2015 to April 2016. The study included 16 burn victims who were divided in three groups: A: patients heard music before dressing; B: patients hear music during dressing; C: patients did not hear music. Results: the average age was 31.8 years (± 14.1) and most of the subjects were male. Lower limbs and trunk were the most affected parts of the body, especially with second-degree burns and which affected an average of 15.8% (± 11.5) of the body surface. There was a predominance of gospel music (50.0%). The music reduced the average heart rate and oxygen saturation, but did not change ventilatory rate. There was a decrease in the average of pain intensity in groups GB (p = 0.0505 and GC (p = 0.0055). During the dressing, the burning was unanimous characteristic for all subjects, in the same manner as verbal reports was the form of manifestation. Conclusion: music proved to be a simple and effective resource in controlling pain in burn victims. Keywords: Burns; Music; Pain.

This research was intended to determine clinical signs and morphological features of blood in the adaptation of imported goat breeds in dairy farming to local climatic conditions, and to establish the formation of new farms in Uzbekistan. The analysis of the clinical condition of the goats during the study showed that changes in weather temperature during the seasons also affected their heart rate. The average heart rate of males in the summer was 63.3-63.5 times, respectively, in the spring - 63.3-63.9 times, in the winter and autumn, it was 63.3-63.4 times. Although there were differences in the respiration of the heifers because of the seasons and their age, they remained at the level of the physiological norm. When the body temperature of young females was observed in the winter, spring, summer and autumn, in the summer, the daytime temperature was 0.4-0.7 °C higher than the morning temperature, and in the evening the air temperature decreased again. The body temperature of young females averaged 39.2 °C in groups in summer, 38.8 °C in spring, 38.9 °C in autumn, and 39.0 °C in winter. Clinical cases of young goats were observed during the study.

The benefits of exercise have been widely recognised for a long time. Exercise increases heart rate, in turn facilitating the effective flow of oxygen and blood around the body and enabling the muscles to use this oxygen and blood in economically beneficial ways. Dr Hideo Nakamura, Department of Health Promotion and Sports Science, Osaka Electro-Communication University, Japan, is exploring the importance of lower limb compression socks for measuring autonomic nervous system (ANS) activity. ANS is a key regulator of the cardiovascular system and helps regulate heart rate and blood pressure. Nakamura is filling a research gap as there is little scientific consensus on the effects. A key focus for Nakamura and his team is on the significance of compression socks for sports to measure ANS activity with heart rate variability during exercise. Nakamura is building on previous studies utilising Tone-Entropy analysis, which is effective as it has high reproducibility and high reliability. Using this method, the researchers will explore mental stress, effects of exercise, pharmacological effects and meditation, among other things. The team used a bicycle ergometer to observe heart rate and ANS activity and found that rhythmic exercise could promote improved blood flow in the veins through compression of the lower limbs. Ultimately, the team hopes to define the subtle differences in parasympathetic nervous activity in individuals wearing compression socks.

Ten healthy pet dogs with an average maximum resting heart rate of 92 bpm that had never been used in studies of auditory stimulation were exposed randomly to one of three sound conditions on each of three occasions within a 5-day period. Posture and behaviour were recorded continuously by video for a total of 20 min over three phases: 5 min before sound exposure, 10 min during sound exposure, and 5 min after sound exposure. Each dog wore a Polar HR monitor throughout testing, and heart rate was recorded by using R–R interval data. Maximum heart rate was significantly greater during heartbeat sound exposure than afterwards, and average heart rate with both heartbeat sound and classical sound showed decrease tendencies.The time spent in dynamic (e.g. movement-related) postures was significantly higher before treatment than during or after under all three conditions. These data suggest that auditory stimuli in dogs may affect physiological responses without necessarily affecting behaviour, and specifically that heart rate may be elevated by auditory exposure to a faster heartbeat.

Wavelet Transform Analysis

The diagnostics of the condition of athletes has become a field of special scientific interest and activity. The aim of this study was to verify the effect of a long (100 km) run on a group of runners, as well as to assess the recovery time that is required for them to return to the pre-run state. The heart rate (HR) data presented were collected the day before the extreme physical effort, on the same day as, but after, the physical effort, as well as 24 and 48 h after. The Wavelet Transform (WT) and the Wavelet-based Fractal Analysis (WBFA) were implemented in the analysis. A tool was constructed that, based on quantitative data, enables one to confirm the completion of the recovery process that is related to the extreme physical effort. Indirectly, a tool was constructed that enables one to confirm the completion of the recovery process. The obtained information proves that the return to the resting state of the body after a significant physical effort can be observed after two days entirely through the analysis of the HR. Certain practical measures were used to differentiate between two substantially different states of the human body, i.e., pre- and post-effort states were constructed. The obtained results allow for us to state that WBFA appears to be a useful and robust tool in the determination of hidden features of stochastic signals, such as HR time signals. The proposed method allows one to differentiate between particular days of measurements with a mean probability of 92.2%.
