Abstract Introduction: Since strength and endurance training has become very popular, we aimed to assess the possibility of hypoxemia determined in peripheral blood during exercise, starting from the hypothesis that a relatively large muscle mass would have a protective effect. Aim: Hypoxemia can cause serious illness and therefore we consider it useful to investigate the occurrence of this phenomenon during exercises of strength or endurance. Methods: The preliminary study was conducted on 8 subjects, both trained and untrained. With a Beurer pulse oximeter, heart rate and oxygen saturation of the capillary blood were measured before, during, and at the end of strength, or endurance or endurance combined with strength training. Results: The results have shown that hypoxemia occurs only under the conditions of high intensity training, which alternates endurance with strength exercises, simultaneously with decreasing heart rate, only in trained subjects and with relatively low muscle mass. Conclusions: The decrease in oxygen saturation in the peripheral blood occurs simultaneously with that of heart rate and it seems that large muscle mass has a protective effect on oxygen desaturation.

Exposure to hypoxia results in vasoconstriction of the pulmonary vasculature (HPV) leading to pulmonary hypertension (HPH) and reductions in blood oxygen saturation and exercise performance. Alleviation of HPV and HPH via vasodilators has been shown to improve blood oxygen saturation and exercise performance in hypoxia. Garlic has been shown to reduce HPV and HPH in rats and has been suggested to have ergogenic effects in hypoxic exercise. We compared the effects of 7 days of supplementation with garlic and placebo on peripheral blood pressures, blood oxygen saturation, heart rate, oxygen consumption, and time to exhaustion during a progressive exercise test to exhaustion in humans under hypoxia (PIO2 ∼ 88 Torr). No significant differences were observed between treatments regarding oxygen consumption, exercise or resting peripheral blood pressures, blood oxygen saturation, heart rates, or exercise time to exhaustion. These results do not support garlic consumption as a method for improving peripheral blood pressure, maximal oxygen consumption, blood oxygen saturation, exercising heart rate, heart rate response, or exercise performance in hypoxia.

Due to the COVID-19 pandemic, face masks have become part of daily life and work. Only few studies have investigated potential negative effects of this measure. It was aim of this study to evaluate whether face masks may affect oygen saturation and heart reate under moderate physical effort. Ten healthy volunteers were asked to climb up four floors (96 steps) with and without a face mask. Oxygen saturation and heart rate were recorded before and after this procedure. Physical activity lead to a slight decrease of oxygen saturation of 3.0% (+/- 3.1) without and 3.7% (+/- 3.8) with face masks (p= 0.28). Heart rate increased by 31.0 (+/- 18.7) and 33.3 (+/- 15.9) beats per minute (p= 0.39). Desaturation was more pronounced in individuals > 40 years, however was uncritical in all cases. This study shows that in healthy adults the use of face masks does not significantly affect oxygen supply nor cause additional cardiac load.

AbstractBackground: The purpose of the following research was to find out the influence of imaginary training based on intention implementation on throw effectiveness of young basketball players, both male and female in stressogenic situations. Individual differences (action vs state orientation) between players were also measured in this research.Material/Methods: 76 players (32 females and 44 males) in the cadet category (15-16 years old) from basketball clubs of Gdansk, Gdynia and Sopot took part in this research. In the first stage all players did a throw efficiency test ERPE 05 under two conditions, and their heart rate was measured. Then players were randomly assigned to one of two groups. The first one did imaginary training based on the influence of intention implementation for 10 days, while the other did not. After 10 days ERPE 05 test under two conditions was run again.Results: Test results showed that intention implementation does not influence effectiveness improvement in stressogenic conditions as far as state-oriented players are concerned, but it does lower the physiological cost of physical effort in form of a decreased heart rate.Conclusions: This research proves that visualization training based on implementation instructions does influence young players’ physiology and significantly lowers their heart rate under stressogenic conditions. However useful, visualization techniques used in this research still need other tests and should be applied for a longer period of time to acutely show how they affect young players’ mental preparation

Tobacco smoke is enormously harmful to human health, there’s no safe way to smoke. The primary objective of this study is to analyze the role of tobacco smoke compounds and their ability to damage the cardiovascular system and, in particular, to interfere with blood pressure (Brachial and radial pressure), heart rate and partly on the percentage blood Oxygen saturation. A new device has been manufactured which is unique for measuring the level of smoke, to obtained privies readings, the device had fixed to the first reference level آ and starting up from it. The effect of smoking has been studied on (26) male passive (26) active smoker volunteer, (14) female passive and (14) female active smoker participants. The results has been showed that the blood pressure and heart rate has been increased with increasing the number of cigarettes in both genders for passive and active smokers. However, this effect for male was more pronounced comparing with females for passive and active smokers. In the case of oxygen saturation concentration percentage, for males the change of oxygen concentration percentage was not stable. In other words, it was fluctuated with the number of cigarettes. But for females the oxygen concentration was decreased but not too much. This means that this effect was not pronounced. this study found آ that the most pronounced effect has been shown by male’s comparison to females for both passive and active smokers. As well as in nonsmoker’s males, the relation between heart rate and smoke level is inversely proportional. While in male and female smokers and female nonsmokers the relation is proportional. In all cases the relation between the smoke level and time of smoking is inversely proportional. Finally males& females are affected differently by tobacco use; the sensitivities to smoke for males are higher than in females for passive and active smokers in both brachial and radial blood pressure measurement.

Transcutaneous Bilirubinometer

Neonatal jaundice occurs in >80% of newborns in the first week of life owing to physiological hyperbilirubinemia. Severe hyperbilirubinemia could cause brain damage owing to its neurotoxicity, a state commonly known as kernicterus. Therefore, periodic bilirubin monitoring is essential to identify infants at-risk and to initiate treatment including phototherapy. However, devices for continuous measurements of bilirubin have not been developed yet. Here, we established a wearable transcutaneous bilirubinometer that also has oxygen saturation (SpO2) and heart rate (HR) sensing functionalities. Clinical experiments with neonates demonstrated the possibility of simultaneous detection of bilirubin, SpO2, and HR. Moreover, our device could consistently measure bilirubin during phototherapy. These results demonstrate the potential for development of a combined treatment approach with an automatic link via the wearable bilirubinometer and phototherapy device for optimization of the treatment of neonatal jaundice.
