The aim of the study was to evaluate the effectiveness of kinesio taping (KT) in anaerobic power recovery after eccentric exercise. The study was carried out on 10 healthy men. The participants performed two 60-min downhill runs with a constant intensity. Peak anaerobic power (PP) and mean power (MP) were measured before and five times after eccentric exercise. Anaerobic power was evaluated with the Maximal Cycling Sprint Test. After the downhill run, passive recovery (PR) and KT (lymphatic application) were applied in random order. A significant decrease in PP and MP was observed at least for 24 h after PR, compared to baseline. After the KT application 24 h after eccentric exercises, anaerobic power was already similar to the baseline measurement. The application of KT significantly improved anaerobic power recovery time after eccentric exercise compared to the period of passive rest immediately prior to testing.

Regular moderate physical activity positively affects health, fitness, and body composition; it regulates the pro- and anti-inflammatory cytokines levels. Vitamin D plays an important regulatory role; its adequate levels correlate with low values of inflammation markers and an increase in muscle strength and fitness in exercising people. The study's aim was to evaluate changes in somatic variables, oxidative stress, and inflammation markers, as well as blood calcidiol concentration in middle-aged healthy women after 12 weeks of aerobics classes—endurance exercises, including choreographic sequences, aiming to improve fitness and motor coordination. The training led to a significant reduction of body mass and fat tissue; it induced an increase in lean body mass. After the 12-week training program, plasma antioxidant status increased (0.65 ± 0.21, p < 0.01) and the concentration of lipid peroxidation products decreased (0.07 ± 0.02, p < 0.001). A significant increase in plasma antioxidant status associated with training could have reduced the level of proinflammatory interleukin as indicated by a positive correlation between these variables (rs = 0.64, p < 0.05). The study proved that a 12-week health training program in physically inactive middle-aged women might provide improvements in their anthropometric parameters and selected biochemical indicators.

Objective: The aim of this study was to determine the effect of a single swimming exercise till exhaustion, in water on the morphological and cytological blood parameters in laboratory rats.Methods: The experiment involved 60 male rats from the Wistar strain, aged 8 weeks and 36 weeks. The animals were separated into 6 groups: 3 groups (I, II, III) of 8-week old animals, and 3 groups (IV, V, VI) of 36-week old animals. The rats in the study groups i.e. II, III, V, and VI were made to swim till exhaustion in water at 4ºC and at 25°C. After the experiment blood samples were collected from each rat and hematological and cytological determinations were completed for each sample.Results: Compared with the control group, in the rats from group II (8-week old, swimming in water at 4ºC) a significant increase was noted in the RBC count, Hb, Ht, and MCHC, and MCH indices, whereas in the rats from group V (36-week old, swimming in water at 4ºC) increases were noted in the MCHC and MCH indices (again when compared with the control group). In the rats from group III (8-week old, swimming in water at 25ºC), compared with the control group, significant increases were noted in the Hb and Ht parameters, as well as in the MCHC, and MCH indices, whereas in the group VI rats (36-week old swimming at 25ºC) -the increase was noted in the MCHC index. No alterations were found in the reticulocyte count, and in poikilocytes during exercise in water at low temperatures in either the 8-week or 36-week old rats.Conclusions: The increases in the majority of blood parameters, testifies to the dehydration of the body during physical exercise which in turn affects the microcirculation function. The lack of alterations in the reticulocyte count in the peripheral blood may, in turn, testify to the ineffectiveness of low temperature during exercise upon the function of the bone marrow.

swimming on blood rheological properties and composition of fatty acids in erythrocyte membranes of untrained older rats. Folia biologica (Kraków) #': 203-209. This is the first report on the effects of a single bout of swimming to exhaustion in cold water on rat erythrocyte deformability, aggregation and fatty acid composition in erythrocyte membranes. The results indicate that there was a significant decrease in body temperature of experimental rats swimming in water at 4°C and 25°C when compared to the control.Erythrocyte aggregation indices did not change after swimming in water at 4°C whereas erythrocyte deformability increased at shear stress 1,13 [Pa] and 15,96 [Pa]. Physical effort performed in water at 4°C when compared to the control group resulted in an increase in monounsaturated and polyunsaturated n-3 fatty acid content in erythrocyte membranes that influenced the increase in their fluidity and permeability even though that of polyunsaturated n-6 fatty acids decreased.Physical effort performed in 25°C water resulted in an increase in saturated fatty acid content and a decrease in all polyunsaturated fatty acids and polyunsaturated n-6 fatty acids when compared to the control group. Swimming of untrained old rats in cold water affected rheological properties of erythrocytes in a negligible way while changes in the fatty acid composition of erythrocyte membranes were more pronounced.

Erythrocytes have high elasticity and the ability to build blood aggregates, they can pass through the smallest capillaries, thus ensuring the transport of oxygen and carbon dioxide in all areas of the vascular system. A decrease in the deformability of erythrocytes may result in reduced blood flow and thereby the cause of many diseases. The increase in blood viscosity is observed, among others, in diabetes, hypertension, obesity and the elderly. Rheological studies of blood in conjunction with morphological and biochemical indices of blood provide valuable information about health of the patient. Any change in the viscosity of blood or plasma should be monitored, as this may indicate a health problem. The aim of the study was to present, based on the available scientific literature, physiological factors influencing changes in rheological properties of blood, for example: exercise, temperature and body weight

It has been assumed that cryotherapy treatments improve athletic recovery and prevent the negative effects of strain caused by training. Body response to low temperatures is reflected in many changes in the hormonal, blood, nervous and immune systems, which may significantly influence tissue regeneration mechanisms. The use of ice or other forms of local cooling is a popular method for the treatment of sports-related injuries. This method is widely used by athletes and allows for fast return to sports activities shortly after injury. The purpose of this paper was to compare the literature reports on three different cryotherapy treatments (ice massage, whole-body cryotherapy, and cold water immersion) and to demonstrate the efficacy of these methods in the athletic recovery.
