The work determines the degree of thermographic suitability of the method of temperature measurement in people exercising on a rowing ergometer. Thermography is gaining popularity in medical diagnostics by measuring the body temperature. Its main advantages are non-invasive, safe and comfortable for patients. It is widely used in the prevention of breast cancer and treatment of osteoarticular injuries. The basis for the use of thermography in medicine is the phenomenon of thermoregulation of living organisms and the emissive property of the skin, which is similar in value to a perfectly black body.To achieve the set goal, 10 people were trained on the rowing ergometer. During the two series of measurements (before and immediately after), the focus was on two areas of the subjects' body: upper limbs and abdomen.The thermographs obtained were analyzed taking into account the physical and physiological parameters of the players and their experience. The conclusions from them seemed to answer the thesis that the thermographic method is suitable for supporting players in planning and improving their training. It has also been shown that training on a rowing ergometer involves many muscle parties in which an increase in the released metabolic heat takes place.

Global Statistics

Global statistics have demonstrated that breast cancer is the most frequently diagnosed invasive cancer and the leading cause of cancer death among female patients. Survival following a diagnosis of breast cancer is grossly determined by the stage of the disease at the time of initial diagnosis, highlighting the importance of early detection. Improving early diagnosis will require a multi-faceted approach to optimizing the use of currently available imaging modalities and investigating new methods of detection. The application of microwave technologies in medical diagnostics is an emerging field of research, with breast cancer detection seeing the most significant progress in the last twenty years. In this review, the application of current conventional imaging modalities is discussed, and recurrent shortcomings highlighted. Microwave imaging is rapid and inexpensive. If the preliminary results of its diagnostic capacity are substantiated, microwave technology may offer a non-ionizing, non-invasive, and painless adjunct or stand-alone modality that could possibly be implemented in routine diagnostic breast care.

Introduction: Bisphenol A (BPA) is a substance commonly used in industry for the production of everyday plastic products. It is also found in thermal paper. Global pollution of the environment by BPA results in constant exposure to its harmful effects. This substance penetrates the skin, respiratory tract and food into the body. BPA, due to its structure similar to estrogens, disturbs e.g. functioning of the endocrine system and increases the risk of certain cancers. Material and methods: The PubMed and Google Scholar databases were used to review the literature. Description of knowledge: Exposure of breast cancer cells to BPA results in increased aromatase synthesis and increased proliferation of ER + cells. Moreover, BPA stimulates the growth of neoplastic breast cancer cells not only at high doses but also at low doses (<25 µg / kg / day). This substance has an affinity for the estrogen receptor. Daily doses of BPA have been found to increase the density of the mammary gland in mammography. Exposure of this substance to human prostate epithelial cells induced the potential of cancer development in prostate cells. Recent studies have shown that BPA causes increased bronchial reactivity and reduced epidermal regeneration capacity, which proves its pro-inflammatory effect. Research proves that BPA reduces the ability to learn and disrupts the Glu / GABA neurotransmitter ratio. Conclusions: The ubiquitous presence of BPA has a negative effect on living organisms. By accumulating in adipose tissue, it exposes us to constant exposure, which is dangerous even in low doses. Increases the risk of infertility and cancer. Acting pro-inflammatory, it increases the susceptibility to allergens. There are calls for the use of BPA-free packaging and for steps to be taken to reduce BPA production. Key words: bisphenol A; BPA; estrogen; mechanisms; receptors; cancer.

Nerve Recordings

Two kinds of nerves, acceleratory and inhibitory cardio-regulator nerves, innervate the heart. They are known to discharge concurrently to maintain an equilibrium state of the body. The nerves are also known to change their frequency of discharge in a reflexive manner to meet the demand from the periphery; such as augmentation of oxygen supply or vice versa. Consequently, the heart exhibits dynamic change in its pumping rate and force of contraction. If the control system fails, the heart exhibits unhealthy state. However, assessment of healthy/unhealthy status is uneasy because we are not able to monitor the nerve activities by non-invasive methods. Therefore, we challenged to detect state of the heart without nerve-recordings. We used the detrended fluctuation analysis (DFA) applying to heartbeat interval time series because DFA has been believed that it can quantify the state of heart. We performed DFA on the EKGs (electrocardiograms) from various living organisms including humans. The objective of this research was to determine whether the analytical technology, DFA, could function as a useful method for the evaluation of the subject’s quality of cardiovascular-related illness and transition to and from a normal healthy state. We found that DFA could describe brain-heart interaction quantitatively: the scaling exponents of (1) healthy, (2) sick-type (such as stressful or arrhythmic states), and (3) unpredictable-death type (such as ischemic heart disease) were corresponded to individuals who exhibited, (1) nearly one, (2) less than one, and (3) greater than one, respectively. We conclude that scaling exponents could determine whether the subjects are under sick or healthy conditions on the basis of cardiac physiology.

AbstractRowing races require developing high level of force and power output at high contraction velocity. This study determined the force-velocity and power-velocity (F-P-V) profiles of lower and upper limbs of adolescent rowers and their relationships with a 1,500-m rowing ergometer performance. The power developed during the 1,500-m (P1500) was evaluated in fourteen national-level male rowers (age: 15.3±0.6 yrs). F-P-V profiles were assessed during bench pull (BP) and squat jump (SJ) exercises. The theoretical maximal values of force (F0), velocity (V0), power output (Pmax) and the F-V relationship slope (S FV ) were determined. The body mass (BM) influence on these relationships was considered using an allometric approach. F0 was 720±144 and 2146±405 N, V0 was 1.8±0.1 and 1.8±0.3 m·s−1, Pmax was 333±83 and 968±204 W and SFV was −391±54 and −1,200±260 N·s·m−1 for BP and SJ, respectively. Upper and lower limb F0 and Pmax were significantly related. P1500 was significantly (P<0.05) correlated to V0-BP, F0-BP, SFV-BP, Pmax-BP, F0-SJ and Pmax-SJ (r²=0.29 to 0.79). BM accounted for more than 90% of these relationships. Rowers’ F-P-V profiles reflect adaptations to chronic rowing practice. F-P-V profiles and rowing performance correlations suggest that BP and SJ exercises are relevant to evaluate young rowers’ explosive abilities.
