Introduction. One possible way of iron loss is sweating. It is unclear how physical activity performed by untrained individuals affects the iron status in sweat. Objective. The purpose of this study was to analyse iron concentration in sweat during 4-week exercise training to determine the changes in iron excretion during follow-up exercises. Materials and method. 43 untrained volunteers participated in the study, 29 of whom completed the full exercise programme. The training programme consisted of exercises on a cycle ergometer and cross-trainer. In the first week, participants exercised for 8 minutes on each device, in the second for 10 minutes, and in the third and fourth weeks they exercised for 15 min on each device. Intensity was submaximal and defined as 85% of maximal heart rate. A sterile sweat patch was placed on the skin between shoulder blades. Results. Concentration of iron on the first and the fifteenth day of exercises was comparable and statistically insignificant. Iron concentration was highly increased on the last day of training in comparison with first (p<0.001) and fourteenth day (p<0.006). The median of iron concentration in 29 samples on the first day of sampling was 21.2 ppb, in the fifteenth – 52.5 ppb, and on the twenty-eighth day – 286.2 ppb. In relation with the sodium concentration, the iron content was also increased on the twenty-eighth day of the training programme (p<0.005). Conclusions. Iron sweat loss significantly increased during the 4-week exercise programme. A possible explanation may be improvement in the thermoregulation mechanism and secretory activity of sweat glands. Iron sweat loss may be an indicator of iron deficiency observed in active individuals.

Introduction: Obesity is an unfavorable state of health as a result of which come in the initial adaptation, that could gradually transform into specific disease condition. Objectives: The aim of the study was to assess the degree of middle-aged men adaptation to obesity in terms of somatic changes, exercise capacity and cardiopulmonary fitness. Materials and Methods: The study involved 12 obese middle-aged men (OG) - BMI = 34.32 ± 4.11 kg/m2. The control group (CG) consisted of 12 non-obese middle-aged men- BMI = 23.72 ± 1.83 kg/m2,with similar body height (BH) to OG. After recording somatic and physiological data at rest, participants were subjected to the bicycle ergometer test (BT) gradually increasing intensity. During the BT aerobic power (AP) was recorded and analyzed along with parameters characterizing the efficiency of the circulatory and respiratory systems at anaerobic threshold (AT) and the maximum load (ML). Results: This study has shown that obese men have a higher body mass (BM), a higher content of fat (BF), an increased lean body mass (FFM) and a higher content of water (TBW) than CG (p <0.001). Absolute and relatively expressed in relation to the FFM respondents’ values of AP and VO2 were similar in both groups and after taking under the consideration the body weight, they were significantly lower in OG than in the CG. Furthermore, adverse effects have been observed that emerged on some cardiovascular and respiratory variables at rest in case of OG; these effects did not occur during physical exertion. Conclusions: Beyond negative changes occurring obesity in the first stage led to favorable somatic adaptation that entails an increase of FFM in OG, which gives a positive impact on the capacity of physical work of obese men and produces a beneficial effect on the resulting compensation impairment in the respiratory and circulatory systems of these subjects.

Opis:
The aim of this study was verification whether an 8-week-long swimming exercise training would induce adaptive changes in body weight in rats and whether possible changes would depend on aquatic environment temperature and animal sex. The exercisetrained groups swam 4 minutes a day, five days a week during eight week of housing. Exercise was performed by swimming in glass tanks containing tap water maintained according to group at 5 ±2°C (cold group) and 36 ±2°C (thermal neutral group). Before and after each week of the experiment, rats were weighed. When comparing the nature of changes in the body weight of rats exposed to swimming exercise training in cold water, attention should be paid to their dependence on sex. There were statistically significant changes in the nature of changes in body weight between male rats and female rats of the cold group (5°C) as early as experimental week 2 until the end of the experiment (p < 0.001). Interestingly, the females exposed to swimming exercise training at 5°C were the only group in which an increase in body weight occurred during experimental week 8 in relation to baseline values.

Opis:
Introduction: The Borg Scale for perceived exertion is well established in science and sport to keep an appropriate level of workload or to rate physical strain. Although it is also often used at moderate and high altitude, it was never validated for hypoxic conditions. Since pulse rate and minute breathing volume at rest are increased at altitude it may be expected that the rating of the same workload is higher at altitude compared to sea level.Material and methods: 16 mountaineers were included in a prospective randomized design trial. Standardized workload (ergometry) and rating of the perceived exertion (RPE) were performed at sea level, at 3,000 m, and at 4,560 m. For validation of the scale Maloney-Rastogi-test and Bland-Altmann-Plots were used to compare the Borg ratings at each intensity level at the three altitudes; p < 0.05 was defined as significant.Results: In Bland-Altmann-Plots more than 95% of all Borg ratings were within the interval of 1.96 x standard deviation. There was no significant deviation of the ratings at moderate or high altitude. The correlation between RPE and workload or oxygen uptake was weak.Conclusion: The Borg Scale for perceived exertion gives valid results at moderate and high altitude – at least up to about 5,000 m. Therefore it may be used at altitude without any modification. The weak correlation of RPE and workload or oxygen uptake indicates that there should be other factors indicating strain to the body. What is really measured by Borg’s Scale should be investigated by a specific study.

Opis:
Aim: Arterial hypertension leads to progressive cardiovascular dysfunction and heart failure. The aim of the study was to assess exercise capacity in hypertensives with the use of a cardiopulmonary exercise test, impedance cardiography and 6-minute walk test with special emphasis on haemodynamic response to exercise workload. Methods: 114 patients (53.5% women, 55.7 ± 9.1 years) were evaluated for reported symptoms, N-terminal pro-B-type natriuretic peptide (NTproBNP) levels, echocardiographic parameters and exercise capacity with 6-minute walk test, cardiopulmonary exercise test and haemodynamic parameters (by means of impedance cardiography). Results: 50% of patients had reported symptoms of impaired exercise tolerance, mostly dyspnoea on exertion (37.7%). NTproBNP levels exceeded 125 pg/mL in 19.3% of patients. Left ventricular diastolic dysfunction was found in 8.8% and heart failure was diagnosed in 6.2% of patients. A wide range of peak oxygen uptake (peak VO2) and 6-minute walk test distance was observed: 19.4 ± 5.2 mL/min/kg and 526.7 ± 112.0 m, respectively. A major proportion of patients demonstrated decreased exercise capacity parameters: 56.1% achieving peak VO2 < 22 mL/min/m2; 45.9% achieving peak VO2 < 80% of the predictive value; 37.3% achieving 6-minute walk test distance shorter than the predicted values. The impedance cardiography recorded at peak exercise: heart rate 147.2 ± 22.4 bpm, stroke volume 110.2 ± 21.8 mL, cardiac output 15.9 ± 4.2 L/min, peak systemic vascular resistance 587.4 ± 168.0 dyn.s/cm5. Conclusions: Although a very small proportion of patients with uncomplicated arterial hypertension meet the criteria for being diagnosed with heart failure, the symptoms of impaired exercise tolerance as well as abnormal results of objective exercise capacity assessments are quite common in these patients.
Cel: Nadciśnienie tętnicze prowadzi do postępującej dysfunkcji układu krążenia i niewydolności serca. Celem pracy była ocena wydolności fizycznej chorych z nadciśnieniem tętniczym z wykorzystaniem sercowo-płucnego testu wysiłkowego, wysiłkowej kardiografii impedancyjnej oraz 6-minutowego testu marszowego, ze szczególnym uwzględnieniem odpowiedzi hemodynamicznej na obciążenie wysiłkiem. Metody: 114 chorych (53,5% kobiet, wiek 55,7 ± 9,1 roku) oceniono pod względem zgłaszanych objawów, stężenia N-końcowego propeptydu natriuretycznego typu B (N-terminal pro-B-type natriuretic peptide, NTproBNP), wykładników echokardiograficznych oraz wydolności fizycznej za pomocą 6-minutowego testu marszowego i sercowo-płucnego testu wysiłkowego, a także parametrów hemodynamicznych za pomocą wysiłkowej kardiografii impedancyjnej. Wyniki: W badanej grupie 50% osób zgłaszało obniżenie tolerancji wysiłku, w tym 37,7% duszność wysiłkową. U 19,3% chorych stężenie NTproBNP przekroczyło wartość 125 pg/ml. Dysfunkcję rozkurczową stwierdzono u 8,8% z nich, ale kryteria rozpoznania niewydolności serca z zachowaną frakcją wyrzutową spełniło jedynie 6,2%. Obserwowano szeroki zakres szczytowego pochłaniania tlenu (peak VO2) i dystansu 6-minutowego testu marszowego, odpowiednio 19,4 ± 5,2 ml/min/kg i 526,7 ± 112,0 m. Wysoki odsetek badanych prezentował obniżone parametry wydolności fizycznej: 56,1% osiągnęło peak VO2 < 22 ml/min/m2, a 45,9% – peak VO2 < 80% wartości predykcyjnej; 37,3% badanych nie osiągnęło należnej wartości dystansu 6-minutowego testu marszowego. W wysiłkowej kardiografii impedancyjnej zarejestrowano na szczycie wysiłku: częstość rytmu serca 147,2 ± 22,4/min, objętość wyrzutową 110,2 ± 21,8 ml, pojemność minutową 15,9 ± 4,2 l/min, opór obwodowy 587,4 ± 168,0 dyn.s/cm5. Wnioski: Objawy obniżonej tolerancji wysiłku i nieprawidłowe wyniki obiektywnej oceny wydolności fizycznej u pacjentów z niepowikłanym nadciśnieniem tętniczym są częste, chociaż niewielki odsetek tych chorych spełnia kryteria diagnostyczne niewydolności serca.

The aim of the study was to reveal age differences in motives and barriers of women attending fitness centers. 157 women aged 17-83 (M=43.86±15.40) participated in the study. All of them were members of fitness centers in the Silesia Metropolis in Poland. The most common reported motives for exercising were health and revitalization. Four motives changed when comparisons were made between age groups: affiliations, competition, health pressure and avoiding diseases. All these motives were stronger in older women. The main barriers to exercising were time constraints and physical limitations. The severity of time barrier significantly decreased with age and in older women it fell into the second place in the hierarchy, giving priority to physical barriers.

Introduction: Research has shown that exercise increases levels of dopamine in cer tain sub - cortical brain regions. Increased dopamine activity in the brain has been linked to increased risk - taking. The purpose of this study was to determine if an increase in risk - taking is apparent in male athletes and non - athletes after strenuous exercise. Method: Ten athletes (age: 20.2±SD year) and ten non - athletes (age: 20.7±SD) in a university setting completed the BART (a validated protocol to asses risk - taking behavior) either after exercise or at r est. Result: Athletes obtained total 24.92 ± 10.99 pumps and Non - Athletes 42.76 ± 16.45 pumps . Discusion: AN C OVA’s showed that there was significant difference between athletes and non - athletes ( p< 0 .0 1) on the risk behavior test. Post hoc tests showed that for non - athletes there was also a significant difference for those that exercise immediately before the risk behavior test, p= 0 .003. This was not the case with athletes, p= 0 .683. Results indicate that while exercise increased risk - taking in the non - athlete subjects, it did not have an effect on the athlete population.

Opis:
Physical exercise has multidirectional impact on the mechanisms of neuroendocrine responses. The regular and moderate stimulates the immune mechanism, whereas the interval may lead to increased susceptibility to infections. In recent years there has been increased interest in the issues of the impact of exercise on the efficiency of the immune mechanisms. In practice, such knowledge may be used to prevent infections in athletes and possible states of overtraining. Among the signaling molecules involved in the immune response of the body to exercise mentioned markers hormonal balance (testosterone, cortisol, estradiol, hormones, pituitary and hypothalamus), the metabolism of proteins and amino acids (balance nitrogen, glutamine, increase in creatine kinase). Review of the current state of knowledge about the change of levels of markers of hormonal system during exercise and suggestions direction of future research in the area of these issues have been taken in this paper. This is a translation of a part of my authorship the original source in Polish ,,Zarządzanie zmianami poziomu wybranych markerów neuroendokrynnych oraz immunologicznych podczas wysiłku fizycznego”. The text was published in an edition of the Scientific Publishing Sophia in 2015.

Opis:
Background. Diseases of the cardiovascular system (CVS) are among the most common diseases of humankind (WHO). Monitoring of blood pressure (BP) is an accessible method for evaluating global hemodynamic processes. The functional reserves of the circulatory system are traditionally determined by the use of functional loading trials and tests. Objectives. The aim of the study is to enhance the information collected during the blood pressure measurement process by studying the levels of adaptation of the CVS to physical activity with morphological, temporal, spectral and correlation analyses of arterial oscillography (AO). Material and methods. In 178 healthy individuals aged 18–20 years, arterial oscillograms were recorded during blood pressure measurement and correlations of the functional reserve of the cardiovascular system at various stages of adaptation to a Ruffier test were investigated. Results. The proposed methods of AO analysis significantly increase the informativeness of the procedure for blood pressure measurement, provide an opportunity to conduct a visual analysis of AOs and to assess the state of the cardiovascular system, its reserve capabilities and its ways of adapting to shoulder compression at rest, after physical load and in the process of recovery. Conclusions. Using the information technologies proposed by the authors of the morphological, temporal, spectral and correlation analysis of arterial oscillograms, their evaluation and clinical interpretation significantly increase the informativeness of the blood pressure measuring process. They can be used for early detection of pre-morbid conditions and functional blood circulation reserves, which will help the physician to more effectively plan a preventative, diagnostic and therapeutic process.

Opis:
There seem to be two tendencies in the Plotinian scholarship concerning spiritual method of the Enneads. First is more general and the other more specific and focused on the analysis of the text. The paper follows the second type of study and attempts to present and analyze Plotinian use of aporia as a spiritual exercise. Traditionally aporia was used as a point of departure for philosophical discussion (e.g. by Aristotle) and sometimes Plotinus follows this tradition. But at other times he uses aporia as a point of arrival – he creates a painful tension due to the fact that discursive thought is unable to know the nature of the One (or, less frequently, also Intellect). The tension becomes a sort of spiritual labor in which the contemplation is born and the tension is released. Several passages from the Enneads are analyzed to show various uses of that method.

The purpose of this study was to evaluate the effect of physical exercise on limited locomotion in the hands of patients who underwent surgery to correct Dupuytren's contracture. We studied the hands of 84 patients with Dupuytren's contracture aged from 30 to 84 years. In all patients, the contracture was removed by performing a partial fasciectomy. Physical exercises were carried out a week prior to surgery and during the postoperative period. Patients were divided into group I, in which the exercise was carried out under the supervision of the authors of this study and group II, in which exercises were performed sporadically and without professional supervision. Measurements were performed on all patients one week before surgery (A), 1 week after surgery (B) and 6 weeks after (C). The range of movement of fingers was measured using a goniometer. The average total loss of finger extension was evaluated, taking due account of the extension loss in the MCP, PIP and DIP joints of all fingers of the treated hand. Rehabilitation treatment included active and passive exercises; in more severe cases the treatment of choice was massage and special equipment to help bear flexion contracture. Test results were statistically analyzed. In all patients, there was an increase in mobility of the fingers. Patients taking part in physical exercise had significantly greater range of finger movement.

Opis:
Addiction to drugs is one of the significant problems in many countries. Opium is a kind of drug that its use goes back to many years ago. Dopamine and serotonin are neurotransmitters involved in the process of addiction. As a result, this study aimed to investigate the blood levels of serotonin, dopamine and physical fitness factors in active and inactive men addicted to opium during their rehabilitation period. This study is a descriptive and Causal after the occurrence. A total of 34 men addicted to opium referring to rehabilitation center had been admitted voluntarily as samples were available in the study. According to a questionnaire answered by them, 16 of them did exercise during their rehabilitation period (active group) and 18 of them did not do any physical activity during this period (inactive group). 5 cc of peripheral blood samples were obtained from both groups and were tested their aerobic capacity, muscular endurance, flexibility, body composition, blood pressure and heart rate. Statistical analysis showed that blood levels of serotonin and dopamine in active group were significantly more than inactive group (p<0.05). In addition, the active group compared with the inactive group had low body fat percent, more muscular endurance, more flexibility, and low resting heart rate (p<0.05). According to the findings, we can conclude that low physical activity but as regular walking can affect blood levels of serotonin and dopamine, and health-related fitness factors of addicted men and as a non-drug treatment is helpful.

Climbing is becoming more and more popular. During 2020 Olympic Games this discipline will be competed for the first time. Individualized diet plays a significant role among representatives of all sport disciplines. The aim of this research was to evaluate the correlation between the level of advancement of sport climbers, selected anthropometric indicators and diet composition. The study involved 36 women and 65 men practicing sport climbing who completed the food record and the survey on the most difficult climbing routes completed. Anthropometric measurements were collected. In the group of men statistically significant, positive correlation between the climbing level and the diet content of fiber, vitamin E, potassium, iron, zinc, and copper, was observed. In the group of women, a statistically significant positive correlation between the climbing level and the participation of vitamin C, potassium, magnesium and copper in the diet was observed. There was a positive correlation of protein, vitamin B2, B6, B12, D, phosphorus, magnesium, iron and copper content, and negative correlation between SFA content per 1,000 kcal of the diet and the climbing level of study participants. No statistical correlation was found between anthropometric parameters and advancement level.

The ongoing development of the modern society may also be easily noticed in sports. Currently, to be able to compete at the highest level at major sporting events, it is essential to conduct scientific research to estimate the individual potential and skill level of an athlete. The aim of this study was to assess the anaerobic endurance in men competing in the running events of 400 m/400 m hurdles based on the estimation of maximum power, as well as selected biochemical and physiological parameters measured in a cardiac stress test at a supramaximal intensity. Seven athletes participated in the study and were subjected to a modified version of the Wingate test (Bar-Or, Dotan, Inbar, 1997; Bar-Or, Inbar, Skinder, 1996) which involved performing three runs of a 12‑second endurance test on a cycloergometer at short intervals. This modification of the test allowed a more precise observation and a better understanding of the physiological and biochemical changes that decrease the efficiency as a result of repeated physical effort, which may significantly affect the assessment of the preparation of an athlete, and thus the assessment of the training process. The most significant changes in the course of the conducted study were observed in the values of the following biochemical parameters: glucose levels, acid–base balance of the blood and lactate levels.

Opis:
The purpose of this study was to evaluate the effects of moderate-intensity resistance exercise on postexercise hypotension (PEH) in the hypertensive. The study was conducted with eighteen hypertensive elderly individuals (20–30 years). They were subjected to two experimental sessions: control session (SC) and 50% (S50%) of 1RM. For each session, subjects were evaluated pre-and postintervention. In the preintervention, the blood pressure (BP) and FVR were measured after 10 min of rest. Thereafter, they were taken to the gym to perform the exercise sessions or remained at rest in each of the equipment during the same time.In the S50% group was composed of a set of ten repetitions of ten exercises, with an interval of 90 s between exercises. Subsequently,the FVR and BP measurements were again performed at 15, 30, 45, 60 and 75 min of recovery (postintervention). The PEH was greater in S50% compared with SC, with the lower value of BP being found at 75 min of recovery for the two sessions (systolic BP:125.21 ±0.98mmHg versus 145.45 ±1.72 mmHg; diastolic BP: 83.60 ±1.67 mmHg versus 95.14 ±0.74 mmHg respectively). Moderateintensity resistance exercise was effective in promoting PEH, this phenomenon being accompanied by a reduction in FVR within the first minute of recovery in the hypertensive young.
