Background: The aims of our study were to investigate the changes in anthropometric and physical parameters and fasting hormonal levels among pre-pubertal female handball players (n = 14, age: 11.53 ± 0.58 yrs, height: 153.36 ± 5.12 cm, body mass: 43.59 ± 6.14 kg) in the pre-season period following 8 weeks of handball training, and to analyze the contribution of hormones, physical performance and anthropometric parameters. Methods: Prior to and immediately following the training period, several anthropometric, strength, and cardiorespiratory variables, including fasting hormonal concentrations (plasma cortisol, estradiol, testosterone and growth hormones) were measured. Athletes performed concurrent resistance and aerobic exercises, including game-based trainings during the 8-week training period. Results: Significant elevations were found in all strength parameters (maximal handgrip strength dominant (D): 16.40%, p < 0.01; non-dominant (ND): 25.15%, p < 0.05; maximal concentric (MVC) torque of quadriceps D: 13.82%, p < 0.05; ND: 12.61%, p < 0.05; MVC torque of hamstring D: 12.14%, p < 0.01; ND: 12.44%, p < 0.01), including plasma cortisol levels (C, 34.30%, p < 0.05) and peak respiratory quotient (5.24%, p < 0.05). Body composition and maximal oxygen uptake (VO2max) remained unchanged. Percentage changes in thigh (r = 0.316, p < 0.05), hand (r = 0.361, p < 0.05), and hip circumference (r = 0.297, p < 0.05) correlated with C changes. Percentage changes in plasma growth hormone levels (GH) contributed to the magnitude of gains in handgrip strength (r = 0.553, p < 0.05). Percentage changes in maximal exercise pulmonary ventilation (MVE) correlated with elevated C (r = −0.592, p < 0.05). Discussion: Changes in anthropometric variables and fasting hormone levels (estradiol, testosterone and cortisol) were poor indicators of developing VO2max and strength during pre-pubertal years. Physical adaptation may not be explained in consideration of the athletes’ hormonal or anthropometric characteristics. Conclusion: Gradually increased training volume followed by a summer break should be applied to youth handball, considering the anti-hypertrophic responses and the inhibitory effect of elevating C on pre-pubertal maturation.

The influence of the kappa-opioid substances dynorphin-(1-13), ethylketocyclazocine (EKC), and U 50488 and mu-opioid substance [D-Ala2-N-Me, p-nitro-Phe4-Gly5-ol]enkephalin (DAGO) on gastric motor inhibition induced by acoustic stress (AS) was investigated in fasted dogs with strain-gauge transducers chronically implanted on the antrum and proximal jejunum. AS induced by 1 h of music (80-90 dB) was delivered through earphones. Starting 40-50 min after the last migrating motor complex (MMC), AS delayed by 114% the occurrence of the next gastric MMC, whereas intestinal motility was unaffected. During AS plasma cortisol increased (P less than 0.05) by 215%, 15 min after the beginning of noise and reached a peak at 30 min. When administered intracerebroventricularly at doses higher than 20 ng/kg, dynorphin abolished the AS-induced lengthening of the gastric MMC cycle. Similar blockade was observed for EKC and U 50488 at doses of 10 and/or 20 ng/kg, but DAGO was unable to affect the AS-induced gastric inhibition at any dosage tested (20-200 ng/kg icv). At doses effective against AS-induced hypomotility, both dynorphin-(1-13) and EKC reduced significantly (P less than or equal to 0.05) the associated maximal increase in plasma cortisol level. Plasma cortisol was unmodified by intracerebroventricular administration of DAGO. None of the agonists affected basal plasma cortisol levels or the increase (0-90 min) in response to intravenous adrenocorticotropic hormone (ACTH, 5 IU). Both EKC (50 ng/kg) and U 50488 (20 ng/kg) were unable to antagonize the inhibitory effect of ovine corticotropin-releasing factor (CRF, 100 ng/kg icv).(ABSTRACT TRUNCATED AT 250 WORDS)

Summary Study aim: Was to investigate the relationship of anthropometrics with handgrip strength (HGS) among Nigerian school children.Material and methods: A total of 200 school children participated in this study. An electronic handgrip dynamometer was used to measure handgrip strength (HGS) in kg. Body height and body weight were measured with a wall-mounted stadiometer in meters and a bathroom weighing scale in kg, respectively. Body mass index (BMI) was then calculated using the formula weight (kg)/height (m2). Also, hand span of both hands was measured from the tip of the thumb to the tip of the small finger with the hand opened as wide as possible. The distance from the distal wrist crease up to the base of the middle finger was taken for palm length and the distal wrist crease to the tip of the middle finger was considered for the measurement of hand length. However, the relationship between HGS and anthropometric parameters was analyzed using Pearson’s product moment coefficient of correlation.Results: The outcome of this study showed that hand and palm length correlated disproportionately and insignificantly (p > 0.05) with both dominant and non-dominant HGS. Also, hand span was found to be a disproportionate correlate of HGS, though such a correlation was only significant (p < 0.05) with dominant HGS. However, BMI and handedness were observed to associate proportionately and significantly (p < 0.05) with HGS.Conclusion: This study therefore concluded that the most important determinants of HGS among Nigerian school children are BMI, handedness and hand span, and thus could be considered as markers of nutritional and health status, as well as physical fitness of these individuals.

Hypertension In Children

Background Hypertension in children is associated with obesity. 7 The renin-angiotensin-aldosterone system has been associated with intra-abdominal fat tissue. Anthropometric parameters for determining nutritional status include waist circumference and waist-hip ratio. Many studies have shown that waist circumference and waist-hip ratio are more precise to determine overweight or obese. Objective To determine the usefulness of waist circumference and waist-hip ratio as hypertensive screening tools for children aged 6-11 years. Methods This analytical study with cross-sectional design and multistage cluster sampling method was conducted in August-September 2017 at a primary school in Bandung, West Java, Indonesia. Subjects underwent height, weight, waist circumference, hip circumference, and blood pressure measurements. Receiver operating characteristic (ROC) curve analysis was done to obtain the area under curve (AUC), cut-off point, sensitivity, specificity, and prevalence ratio. Results Subjects were 325 children consisting of 187 males and 138 females. Hypertension was diagnosed in 47 children (37 males and 10 females). Mean waist circumference and waist-hip circumference ratio were significantly higher in the hypertensive group than in the normotensive group. The hypertensive group had a mean waist circumference of 72.6 (SD 12.8) cm, AUC 0.779 (95%CI 0.730 to 0.823; P<0.001), cut-off point >65 cm, sensitivity 66.0%, specificity 76.3%, and prevalence ratio 4.55. This group had mean waist-hip ratio of 0.94 (SD 0.10), AUC 0.724 (95%CI 0.672 to 0.772; P<0.001), waist-hip ratio cut-off >0.91, sensitivity 59.6%, specificity 77.0%, and prevalence ratio 3.73. Conclusion Waist circumference >65 cm or waist-hip ratio >0.91 can be used to screen for hypertension in children aged 6-11 years with negative predictive values of 92.0% and 91.8%, respectively.

Background. Saliva is a popular biospecimen for the measurement of hormones, yet fluctuations in hormone levels limit the extent to which saliva can address focusing on basal or long-term levels. Hair steroid assays return basal hormonal levels by collapsing across short-term hormonal variability, including menstrual cyclicity. Here we sought to validate a hair bioassay methodology that can capture stable estradiol levels from both human and monkey hair samples. Methods. Three projects were involved to examine hair-saliva correspondence and estradiol stability in hair. Project 1. Saliva samples were collected once per week for two cycles in 11 emerging adult women. Hair samples were collected at the end of each menstrual cycle and were segmented by 1 cm for the first 4 cm to reflect the past four serial months’ hormone levels. Project 2. Hair samples collected from 23 adolescent participants (Mage = 14.1, 56.5% female) were cut to three 1.5 cm segments from the scalp end. Project 3. Two hair samples were collected from two adjacent skin areas on each monkey (N = 8, 75% males). Whole hair samples were sheared and used for assay without segmentation. Hair biospecimens were processed using a double-extraction protocol validated in this study, then assayed using commercially-available enzyme-immuno-assays for estradiol. Results. Project 1. Hair estradiol concentrations were significantly associated with averaged saliva estradiol levels (r = 0.77, p&lt; .05). Estradiol levels in two consecutive segments were significantly associated (1st vs. 2nd: r = .63, p &lt; .01; 2nd vs. 3rd: r = .49, p &lt; .05; 3rd vs. 4th: r = .53, p &lt; .05). Project 2. Estradiol concentrations were significantly correlated between the first two successive hair segments from the scalp end (r = .69, p &lt; .01). Project 3. Estradiol levels in the two hair samples from each monkey were significantly correlated (r = .66, p &lt; .05).Discussion. Results suggest hair captures valid and reliable average estradiol concentrations using a double-extraction protocol that is applicable for both human and monkey hair. The measurement of hair provides valuable information on individual differences in average estradiol levels across months. Results also indicate that it is feasible and reliable to collect the first 2-3 centimeters of studies in which basal estradiol levels in the past 2 to 3 months are of interest as a stable hormonal index for different species.

Abstract Background: Protein-energy wasting (PEW) is a common complication of maintenance hemodialysis (MHD) patients. This study aimed to explore the PEW evaluation method in MHD patients. Methods: Clinical data, physical parameters, laboratory values, and a questionnaire survey of MHD patients were collected from PEW and non-PEW patients in our hospital from September to December 2019. Analysis of variance was used to assess the difference between the two groups. ROC analysis was used to compare the diagnostic efficacy of physical measurement and nutrition scores and find the appropriate evaluation criteria for clinical application. Results: 1. There were statistically significant differences in many physical parameters between the two groups (p<0.05). 2. ROC curve analysis showed that the diagnostic efficiency of a single physical measurement or nutritional score was not high, and multiple indexes should be combined. 3. The simplified Pew risk score formula was 27.4 + abdominal circumference + 0.4 * main handgrip strength - 3.2 * body mass index -1.9 * upper arm circumference, which had a sensitivity of 67.7% and specificity of 94.4% at AUC of 0.864 and cutoff of 0.043346. Conclusion: A combination of abdominal circumference, main handgrip strength, BMI, and upper arm circumference could comprehensively evaluate PEW to improve the diagnostic efficiency.

Background. Several studies have shown an association between codon 16 polymorphism of theβ2AR gene and obesity.Methods. We studied the association between Arg16Gly polymorphism and obesity and its influence on anthropometric parameters, lipids, insulin resistance and leptin in Saudi individuals. The study group included 329 individuals (males: 109 and females: 220). Metabolic parameters, including glucose, lipids, insulin, and leptin were analyzed and anthropometric parameters including waist and hip circumference, waist/hip (W/H) ratio, and body mass index (BMI) were measured and HOMA-IR was calculated. Genotyping was conducted by DNA sequencing of 353 bp fragments, carrying the Arg16Gly polymorphic site.Results and Conclusion. Overweight and obese subjects had a significantly higher frequency of Gly16 (0.375 and 0.38, resp.) compared with normal-weight subjects (0.200). In addition, subjects carrying Gly16 allele regardless of their BMI had greater waist and hip circumference, W/H ratio, plasma lipids, leptin, glucose level, and insulin resistance as judged from the HOMA-IR, compared to those with the wild-type allele. The findings of this study show a significant association between the Arg16Gly polymorphism inβ2AR gene and the development of insulin resistance, overweight, and obesity in Saudi populations with an influence on the levels of lipid and leptin.

SUMMARY Progesterone, 17α,20α-dihydroxypregn-4-en-3-one, androstenedione, total unconjugated oestrogen and oestrone sulphate have been measured by radioimmunoassays in maternal utero-ovarian venous, maternal peripheral venous and/or foetal posterior vena caval plasma from six sheep bearing bilaterally adrenalectomized lambs, in which premature parturition was induced by administration of glucocorticoid. Three of the ewes were ovariectomized, and in one of these three animals the foetal testes were also excised, at the time of foetal adrenalectomy. Adrenalectomy was judged to be complete on the basis of plasma cortisol levels in the neonatal lambs, and by examination of the site of ablation at necropsy. In all cases foetal administration of glucocorticoid led to the onset of labour, and lambing, and in all animals the hormonal changes preceding parturition were indistinguishable (either qualitatively or quantitatively) from the changes observed in animals carrying intact lambs. Since therapy with glucocorticoid alone successfully compensates for ablation of the foetal adrenal cortex, it is suggested that glucocorticoid is the only adrenal product required to cause parturition, and that foetal adrenal secretion of androgens may be unnecessary.

Anthropometric Profile

Background. Knowledge of the peculiarities of anthropometric indicators, body weight components, and somatotype of athletes is important for coaches, sports scientists, and sports physicians at all stages of perennial training, starting with children’s sport. Often this is seen as an important indicator for identifying talented children in sport. The aim of this study was to determine how the anthropometric and body weight profile of young swimmers (11–12 years) significantly changes during the training period, and the correlation of these indicators with the competition results in the chosen event.Methods. The study included 24 young (aged 11.7 ± 0.5 years) national level swimmers – girls (n = 14) and boys (n = 10) with 3 to 4 years of sports experience in the national competitions and demonstrating high results in their age group. We investigated longitudinal anthropometric measurements, body mass components, established the somatotype and handgrip strength. The change of indicators was analysed during the training period of five months as well as its correlation with the result in the chosen sport. Sports results were rated by FINA ranking points.Results. The anthropometric longitudinal and transverse dimensions of girls and boys increased during the study period, however, there was no difference between the sex groups except for the length of the foot (it was higher in the group of boys, p < .05). The analysis of body weight components showed that girls had higher body fat mass and a percentage of body fat than boys (p < .05). The results of boys’ swimming had statistically significant links with their height (r = .857), foot length (r = .805), body weight (r = .857), lean mass and muscle mass (r = .927) and right handgrip strength (.786). There was no significant correlation between these indicators in the group of girls.Conclusion. The results of the study suggest that the characteristics of the anthropometric profile as a prognostic indicator for the viability in the chosen sport for boys were more significant than for girls.
