Aim: The aim of this study was to determine the relationships between socioeconomic factors (SES), anthropometric characteristics and motor abilities of female university students. Materials and Methods: The study was conducted in 2000-2018 on 3955 female university students aged 19.72 ± 0.75 years who were randomly selected from the population of students attending obligatory physical education (PE) classes. The participants' body mass and height were measured, and the students participated in 13 motor ability tests that assessed their speed/agility, flexibility, strength, endurancestrength, and endurance abilities. Multiple independent samples were compared using the KruskalWallis test or the mean-ranks post-hoc test when significant differences were observed in the participants' motor abilities. Results: Statistically significant differences in the participants' body mass, body height, BMI and motor abilities (speed/agility, flexibility - partly, strength, and strengthendurance) were associated with differences in the students' SES. Greater mean differences in SES were associated with differences in the anthropometric and motor characteristics of students. Environmental factors such as the place of permanent residence, monthly budgets, mother's and father's educational background were least likely to be associated with female students' endurance abilities. Conclusions: Female students who had higher monthly budgets, resided in large cities, and had better educated parents were generally taller and had a higher level of motor abilities. An inverse relationship was noted between motor abilities vs. body mass and BMI.

Purpose. The purpose of the conducted research was to determine the impact of training on the time spent covering a distance of 500 m on a rowing ergometer as well as an examination of the representativeness of the adopted sample in developing a method of providing an accurate and reliable assessment of the obtained results when measuring the short-term endurance capacity in a female student population. Methods. The research was conducted on 96 full-time female students at the UWM in Olsztyn using a "Concept II Indoor Rower" rowing ergometer, where the impact of regular training on the time of covering the 500 m distance was analysed. The results of the research were statistically analysed in order to examine the conformity of the obtained distributions in the time spent in covering the simulated distance, the subjects' mass and height, an adopted CPI value (height/body mass ratio), BMI index and the female students' slenderness ratios all within normal distribution. Mathematical (regressive) models describing the impact of the adopted factors on the time of covering the simulated distance were then developed. Results. On the basis of the obtained results and the developed mathematical relationships, it was noted that with further repetition of the exercise, the mean time of covering the 500 m distance on a rowing ergometer (based on the results obtained between the 1st to the 10th trial) decreased from ca. 15-20 s. The phenomenon of shortening the covered time may be caused by an improvement in the level of short-term endurance capacity as well as becoming familiarized with the movements (learning) performed on the rowing ergometer. Conclusion. A one-time attempt at covering the 500 m distance on a rowing ergometer, at the fastest pace possible and performed once a week, was found to improve the endurance capacity level of the studied subjects. The developed method found herein can be applied as an accurate and reliable test in assessing the time of covering the simulated 500 m distance on a rowing ergometer when determining short-term endurance capacity.

Purpose. The aim of the study was to develop a mathematical model to determine correlations between selected somatic traits and indoor rowing test results over a distance of 500 m as well as differences in the level of motor fitness of students of the University of Warmia and Mazury in Olsztyn. Material and methods. The research was carried out on a group of 274 full-time UWM students with the aid of Concept II Indoor Rower. The analysis concerned the effects of students' body weight and body height, year of study and the time required to cover the distance of 500 m during an indoor rowing test. Analysis of variance and regression analysis with stepwise elimination of the polynomial degree and form were used. Results. Only 15 subjects (5.5% of the sample) achieved the highest level of motor fitness, i.e. covered the distance under 92.7 s. A mathematical model describing the effects of decisive variables on the dependent variable was a model of regression of multiple variables of the 2nd degree. The exogenous variables were subjects' body height and body weight. Conclusions. The proposed mathematical model of regression of multiple variables of the 2nd degree can be useful for selection of individuals with predispositions to practice rowing at the academic and recreational levels. The proposed method of mathematical model development should be regarded as an algorithm for other, more versatile models involving additional variables.

Introduction: Veronica Sherborne Developmental Movement Method is of the most frequently used forms of therapy for improving children with various mental and motor dysfunctions. Sherborne understands movement as not just a physical activity, but the transfer of deep respect for man, faith in man's ability to develop and improve, the joy of close contact. The research objective was to verify the importance of persons taking an active part in the therapy of Veronica Sherborne Developmental Movement with children with moderate intellectual disability on cognitive, emotional, social and motor development. Material and methods: The research was conducted by the workers of special education centers. It involved 39 persons aged 7-8 years. The experimental group was composed of 39 persons as that was the number of patients remaining in disposal of the deliberately selected special education centers. The activities were conducted for 9 months. Results: The results showed that the persons who accompanied the children in therapy had a positive influence on their development but in a differentiated manner. The evaluation made with the use of the Behavior Observation Scale showed that the greatest progress in the cognitive, social and motor development was made by those children who were accompanied in therapy by the workers of special education centers, and then pupils and volunteers. It was also demonstrated that people who were actively involved in therapy, favorably influenced the results of the Evaluation Procedure. The smallest improvement was observed when a pupil was a supporting partner. Conclusions: Persons taking an active part in therapy significantly influenced its results among children with moderate intellectual disability. The greatest progress was noted when the worker of the special education center and a volunteer were the pair partners.

Study aim: Regular exercise training is thought to modify cardiac autonomic control. One of the body’s responses to training stimuli is heart rate variability (HRV). The use of HRV in the management of sport training is a common practice. The objective of the present study was to assess the impact of the physical activity level on HRV of 1st league national volleyball players prior to and during the competition period. Materials and methods: The study involved 11 players whose HRV was evaluated during the two analysed training periods. Selected indicators of spectral analysis (total power, %VLF, % LF, % HF powers, LF n.u, HF n.u, and LF/HF powers) as well as time analysis (HR, RR, RMSSD, NN50) were assessed on the basis of recordings. Results: The studies conducted in the pre-competition and competition periods showed significant differences in the parameters of spectral VLF% analysis and time NN50 analysis. In the competition period, a significant increase in VLF [%] may be the result of increased psycho-physical arousal, when compared to the pre-competition period. ] Conclusions: Resting bradycardia, assessed on the basis of time analysis indicators, may be the result of internal changes in the sinus node, which reflects the impact of long-term training on the cardiac conduction system. A high level of physical activity of volleyball players in the tested periods could have contributed to a reduction in vagal tone and a shift in the balance of the autonomic nervous system in the direction of the sympathetic system, which may be the result of overtraining

Aim: The aim of this study was to determine the effect of a 15-minute bathing session in a Finnish sauna on changes in systolic and diastolic blood pressure (SBP and DBP, respectively), heart rate (HR), and body mass. The effects of grouping variables (age, sex, BMI, frequency of sauna use, history of sauna use) were taken into account in the analysis. Materials and Methods: A total of 60 women (33.6±13.1) and 42 men (33.8±12.5) aged 17 to 79 participated in one 15-minute sauna session (temperature: 90-91°C; relative humidity: 14-16%) in December 2019, in the city of Wrocław, Poland. The participants' body mass, SBP, DBP and HR were measured before and after sauna. Body height was measured only before sauna. Results: Sauna induced significant changes in the participants' physiological parameters. Systolic blood pressure decreased (p<0.05) in both sexes, in older participants (p<0.001) regardless of their BMI, and in participants who had rarely used sauna and had used sauna for a minimum of several years. A significant decrease in DBP (p<0.001) and HR values and a significant loss of body fluids (p<0.001) was noted in both sexes regardless of age, BMI, frequency and history of sauna use. Conclusions: A 15-minute sauna session has a beneficial effect on the circulatory system and can be incorporated into cardiovascular therapies. Regular sauna use is an important factor, and optimal results can be achieved by visiting sauna several times a week.

Background: Finnish sauna is presently the most popular type of thermal therapy in Europe. Saunas are widely available in aquaparks, SPA centers and hotels. In Scandinavian countries sauna is regarded not only as a form of treatment, but as a part of the national lifestyle. Objective: The aim of this study was to evaluate sauna-induced changes in systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR) and body mass in healthy men. Methods: Thirty healthy men aged 20-49 years (mean age: 31.2±11.3 years) attended four 12-minute Finnish sauna sessions (temperature: 90°C, humidity: 14-16%) with 6-minute breaks in between sessions, including cold water immersion for 1 minute. The participants’ physical activity (PA) levels were evaluated with an IPAQ questionnaire. Sauna bathers’ body composition, BP and HR were measured before the first and after the fourth sauna session. Results: A significant (p < .001) decrease in SBP and DBP values was noted in response to sauna regardless of the bathers’ body mass, age and PA levels. The average HR increased significantly in younger, slimmer and more physically active participants. Sauna treatment induced a significant decrease in body mass loss regardless of all independent variables. Conclusions: Repeated 12-minute Finnish sauna sessions have a beneficial influence on the cardiovascular system. Finnish sauna can be recommended for healthy men with average and high PA levels as a means of decreasing BP. Body mass loss, on the other hand, is related to the loss of body fluids as a result of sweating.
