TL;DR: In this article , the authors reviewed the most recent research on the factors that most influence hydration and found that sweat loss and fluid intake are two of the most important factors for hydration status.
Abstract: The aim of this study to review the most recent research on the factors that most influence hydration. This study review using the literature research from google scholar, PubMed, and Elsevier. Many athletes after training experience dehydration due to not consuming enough fluids and electrolytes before, during training, and competition. To assess hydration status cannot be determined by just one factor. The general recommendation of hydration status measures using accurate biomarkers to detect body water fluctuations of 3% of total body water (TBW), using dehydration index, body mass, or color of urine. Therefore, monitoring hydration status is very important to maintain athlete performance. Exercise increases hypohydration due to fluid losses so that should be given to fluid supplementation and intake from certain food for each athlete. The factor that most influences the athlete's hydration is sweat loss and fluid intake.

TL;DR: It can be said that the recreational futsal as physical activity is an effective tool to improve body composition not only in passive football players but in all persons of all ages regardless of gender.
Abstract: The purpose of this study was to evaluate the impact of recreational futsal on passive middle-aged footballers in body composition. Materials and methods. The research was conducted on a sample of 58 men aged from 30 to 40, average age 35.88 ± 2.39. The sample was divided into two groups. The first group included 29 passive football players (average age 35.58 ± 2.36) who were engaged in recreational futsal 2-3 times a week, and the second group included 29 passive football players (average age 36.17 ± 2.42) who weren’t engaged in recreational physical activity. The body composition was assessed by TANITA BC-601, the method of bioelectrical impedance, which became a reference method in research studies in the body composition analysis. The variables obtained were: body height (cm), body weight (kg), fat mass (%), muscle mass (kg), bone mass (kg), body mass index (kg/m2), calorie consumption – daily calorie intake (kcal), vitality of the body, quantity of water in the body (%), visceral fat (%). Results. Groups are not distinguished in the variables body height (HBH), calorie consumption – daily calorie intake (DCI), vitality of the body (BMR), and quantity of water in the body (TBV) because p > 0.05. In the variables where body mass, body fat tissue and muscle mass were assed, namely body weight (BWT), fat mass (BFP), muscle mass (TBM), bone mass (BMD), body mass index (BMI) and visceral fat (AVF), a statistically significant difference was gained p < 0.05 in favor of the group of passive football players who were involved in recreational futsal. Conclusions. It can be said that the recreational futsal as physical activity is an effective tool to improve body composition not only in passive football players but in all persons of all ages regardless of gender. Intensity and duration in recreational futsal is an effective way to reduce body fat in the population of passive middle-aged football players.

TL;DR: The blood to extracellular volume ratio in haemodialysis patients is close to one-third assumed under physiologic conditions and that this ratio remains unchanged in spite of UF, confirming previous findings that the vascular refilling volume is only about 70% of Uf volume during dialysis.
Abstract: Blood volume (BV) is tightly controlled by the kidneys and the interstitial space plays an important role in this control. The interstitial space serves as a volume buffer in case of volume excess or volume depletion. It is the purpose of this buffer to maintain adequate circulatory and diastolic filling pressures, and thereby to maintain a functional circulation of the blood. BV is approximately one-third of the extracellular volume (ECV) under physiologic conditions. In haemodialysis patients without renal function, ECV is expanded because fluid is accumulated in the interdialytic period. This volume excess has to be removed during dialysis by ultrafiltration (UF) of blood. The question therefore arises, i) how is this volume excess distributed between intra-and extravascular compartments in dialysis patients and ii) how is this distribution affected by UF? Blood and extracellular volumes were measured in 79 stable chronic haemodialysis patients with moderate volume overload (1.85 ± 1.22 L). Immediately before treatment, ECV and volume overload were evaluated by bioimpedance spectroscopy using the body composition monitor [BCM, Fresenius Medical Care (FMC), Bad Homburg, Germany]. ECV at the end of treatment was calculated by subtracting the intra-dialytic weight loss from pre-dialysis ECV. The actual BV at the beginning of dialysis was determined by indicator dilution, using an online infusate bolus of 240 mL which was administered immediately after the beginning of the dialysis session and subsequent calculation using the data of the relative BV monitor integrated into the haemodiafiltration machine 5008 [Fresenius Medical Care (FMC), Bad Homburg, Germany]. BV at the end of the dialysis session was calculated from the measurement of BV at the beginning and the relative BV at the end of dialysis. The relationship of BV (5.76 ± 1.54 L) to ECV (17.91 ± 3.90 L) was 0.321 ± 0.039 at dialysis start and 0.319 ± 0.040 at the end (BV 5.20 ± 1.41 L, ECV 16.22 ± 3.57 L). The mean deviation between pre- and post-dialysis was −0.002 ± 0.018. There were strong correlations (P < .001) between BV and ECV both at the beginning (r = 0.88) and at the end (r = 0.88) of dialysis. These data show that i) the blood to extracellular volume ratio in haemodialysis patients is close to one-third assumed under physiologic conditions and that ii) this ratio remains unchanged in spite of UF. The constant relationship between the two compartments is maintained under conditions of haemodialysis with the rapid volume removal by UF. This confirms previous findings that the vascular refilling volume is only about 70% of UF volume during dialysis. Despite the lack of kidney function, the mechanisms to adequately distribute volume excess between intra- and extravascular appear to be maintained. The volume shift between plasma and interstitial volume prevents both an inter-dialytic cardio-vascular burden and intra-dialytic hypotension. Therefore, haemodialysis patients with moderate volume overload are likely to be adequately protected from volume-related complications. To the best of our knowledge, this is the first time that these relationships are reported in dialysis patients.

TL;DR: Two normalized ratios were identified, which were associated with a high risk of mortality in the population of dialysis patients, which are related to male gender, older age, con-comitant diseases, lower body weight, and BMI.
Abstract: Hemodiafiltration on-line (HDF OL) cannot be considered sufficiently studied in terms of its effect on the outcome. THE AIM. To identify the possible relationship of individual anthropometric, laboratory data and parameters of the prescribed treatment regimen with better survival when using the HDF OL. PATIENTS AND METHODS. A retrospective study of the EuCliD database of patients treated with HDF OL in 27 Fresenius Medical Care centers in the Russian Federation during 2014 was conducted. All patients received postdilution HDF OL procedures at least 3 times a week, lasting at least 12 hours a week, with adequacy of Kt/V procedures of at least 1,4. Data from survivors (9616) and deceased (370) patients were compared. The analyzed indicators were: gender, age, treatment experience, body weight, body mass index (BMI), body surface area (BSA), total body water volume (TBW), the volume of distribution (V Urea BCM), presence of diabetes mellitus, coronary heart disease, heart failure, as well as the parameters of the procedure: effective weekly dialysis time, Kt/V, effective in-fusion volume (EIV), effective convection volume (ECV). RESULTS. Risk factors for death in patients with CKD 5D treated with HDF OL include male gender, older age, con-comitant diseases, lower body weight, and BMI, shorter effective weekly dialysis time, lower EIV and ECV values, Kt/V, higher hypercalcemia, hypoalbuminemia, lower hemoglobin levels, higher b2-microglobulin levels, and CRP. Сomparing the normalized BMI, BSA, TBW, V Urea BCM indicators, we identified those that were associated with a high risk of mortality in the population of dialysis patients. CONCLUSION. As a result of this work, two normalized ratios were identified (the median ratio of effective infusion volume to body surface area and the median ratio of effective convection volume to body surface area), which were associated with a high risk of mortality in the population of dialysis patients.

Abstract: <p> This work considers adults’ acumen to be assessed with four quantified indices like cell membrane capacitance (CM), total body fat (TBF), total body water (TBW), and total body impedance (TBI) that reflect subjects’ cerebral stress handling competence in the face of intense cognitive task. Primarily, an electrical model of the epithelial tissue structure (ETS) has been represented and anatomized in the light of hormonal change happens inside human body to propose a number of preambles. An intelligence quotient (IQ) test designed to agitate mind has been conducted right before measuring body composition parameters. Finally, comprehend data operations and juxtaposed investigations to vindicate model-implied preambles along with quantified indices were made by comparing them to IQ test outcomes. Effectively innervated nervous system with homeostasis endocrine human anatomy has been reported to have CM, TBF, TBW, and TBI in the range of 1.0-2.1nF, 7.9-20%, 56.8-80%, and 470-550 Ω respectively for the subjects whose acumen is classified as “Class-A”, while “Class-B” is also presented with distinct quantified indices. These indices are expected to be paradigm of non-invasive neurological disorder detection, additionally, it can also be applied in categorizing youngsters before deploying them to highly productive tasks suitable for them. </p>
