title: Body composition and performance variables differences in female volleyball players by agegroup and playing position

description: Abstract The aim of the present study was to evaluate the age and inter- and intra-position differences in the anthropometric variables and physical performance in young female players of Brazilian women's volleyball. Fifty-eight female volleyball players participated, divided into 3 age groups: (a) 14 and under (n=20; mean age = 12.6±0.7 years), (b) between 14 and 17 (n=31; mean age = 15.6±1.2 years), and (c) over 17 (n=7; mean age = 18.9±0.9 years). In addition, the players were also divided according to their positions: setters (n=7), opposites (n=13), passer-hitters (n=17), middle blockers (n=12) and liberos (n=9). Anthropometric characteristics, flexibility, strength / resistance abdominal muscles, pushups, explosive power of the arms, jumping abilities, shuttle run and 20-m sprint tests were evaluated. Analyses showed differences among age and playing positions for the height and bone mass (p&lt;0.05). In the fitness assessment, no differences were found between playing positions (p&gt;0.05). However, differences were found among for age groups horizontal jump, shuttle run and 20-m sprint, with players &gt;17 performing better than &lt;14 and between 14-17 years of age (p&lt;0.05). These results demonstrated that the height, bone mass and horizontal jump, shuttle run and 20-m sprint are age dependent, while physical performance independent on the playing positions.

title: Power and agility testing within the NBA pre-draft combine

description: Abstract Considering agility is a prerequisite for basketball performance and several agility tests have been used during the pre-draft assessment of the National Basketball Association (NBA), the aimed of this study was to examine the associations between pre-draft athletes´ performance scores in NBA draft combine testing protocol. The performance of 480 athletes invited to the NBA pre-draft assessment from 2010 to 2017 was considered. Tests in the NBA Draft Combine considered in this study included the Shuttle Run Test, Lane Agility Test, Sprint Test, and Jump Test (standing vertical leap). Zero order correlations were calculated to examine the associations between performance tests by fitting Bayesian linear regression models. Among running testing, both Shuttle Run Test [r=0.45, 95% confidence interval (CI) 0.34 to 0.56) and Sprint Test (r=0.45, 95% CI 0.37 to 0.54) were moderately associated with the Lane Agility Test. The association between the Sprint Test and Shuttle Run Test was moderate at best (r=0.27, 95% CI 0.16 to 0.38). Correlations between Jump Test and running tests were moderate to large, ranging from -0.51 to -0.19 (Lane Agility Test: r=-0.33, 95% CI -0.42 to -0.24; Shuttle Run Test: r=-0.19, 95% CI -0.31 to -0.07; Sprint Test: r=-0.51, 95% CI -0.59 to -0.43). As a conclusion, we found a moderate to large correlations between the tests performance of the NBA Draft Combine, implying that the overall procedures may provide in part overlapping information about basketball maximal short term performance.

title: Social support, self-efficacy and level of physical activity of students aged 13-15 years

description: Abstract The aim of this study was to verify the relationship, the population attributable fraction (PAF) and the relative risk reduction (RRR) of social support and self-efficacy with level of physical activity in students. Probabilistic cross-sectional study with 1,472 students aged 13-15 years. Gender, age, social support from parents and friends, self-efficacy and levels of physical activity were evaluated through questionnaires. Data analysis was performed using Poisson regression with robust variance, PAF and RRR, adopting p≤0.05. A total of 56.1% (n = 826) of students were considered active, boys (68.7%) presenting the largest proportion. Social support from parents was positively associated with physical activity in boys (PR: 1.28, 95% CI: 1.12-1.48, PAF = 21.88) and girls (PR: 2.00; 95%CI: 1.59-2.51, PAF = 50.00). Social support from friends was positively associated with physical activity in boys (PR: 1.34, 95%CI: 1.16-1.54, PAF = 25.37) and girls (PR: 1.32, 95%CI: 1.06-1.64, PAF = 24.24). Self-efficacy was not associated with physical activity. Social support was associated with levels of physical activity, and PAF indicated that the absence of high social support from parents and friends might reduce the level of physical activity in adolescents.

title: Oxygen consumption and heart rate obtained in a ramp protocol are equivalent during exercise session of rectangular loading at ventilatory thresholds for athletes

description: Abstract Training near or at ventilatory threshold (VT) is an adequate stimulus to improve the thresholds for sedentary subjects, but a higher intensity is necessary for conditioned subjects. The choice of cardiopulmonary exercise testing (CPx) protocol has an influence on VTs identification and can reduce their reliability for exercise prescription. This study tested if VO2 and heart rate (HR) corresponding to first (VT1) and second ventilatory threshold (VT2) determined during a ramp protocol were equivalent to those observed in rectangular load exercises at the same intensity in runners elite athletes (EA) and non-athletes (NA). Eighteen health subjects were divided into two groups: EA (n = 9, VO2max 68.6 mL·kg-1·min-1) and NA (n = 9, VO2max 47.2 mL·kg-1·min-1). They performed CPx and 48h and 96h later, a continuous running lasting 1 h for VT1 and until exhaustion for VT2. The results showed that EA at VT1 session, presented delta differences for VO2 (+9.1%, p = 0.125) vs. NA (+20.5%, p = 0.012). The Bland-Altman plots for VT1 presented biases of (4.4 ± 6.9) and (5.5 ± 5.6 mLO2·kg-1·min-1) for AE and NA, respectively. In VT2, the VO2 and HR of the NA showed biases of (0.4 ± 2.9 mLO2·kg-1·min-1) and (4.9 ± 4.2 bpm). The ramp protocol used in this study was inappropriate for NA because it underestimates the values of VO2 and HR at VT1 found in the rectangular load exercise. The HR showed good agreement at VT2 with CPx and may be a good parameter for controlling exercise intensity.

title: Comparison of maturation and physical performance in basketball athletes of different playing positions

description: Abstract The aim of this study was to compare the characteristics of somatic maturation, anthropometric and physical performance (vertical jump and aerobic power) in young basketball players of different playing positions (under 13 years) and analyze these relationships using Peak Height Velocity (PHV) as a measure of somatic maturation. For this, 26 male athletes were evaluated. Anthropometric variables were: body mass, standing and sitting height, and length of lower limbs. Maturation was determined by age at PHV. Physical performance was determined by lower limb power (counter movement jump - CMJ) and aerobic power (Intermittent Recovery Test) tests. MANOVA reported significant differences (p&lt;0.05) among playing positions regarding variables Maturity Offset, estimated PHV age, standing height, sitting height, estimated leg length, body mass and Yo-Yo IR1. In addition, it was identified that point guards reached estimated PHV at later age than their peers who act as small forwards and centers. Regarding CMJ, no significant differences were identified among playing positions, but in relation to aerobic power, point guards and small forwards presented higher performance. These findings confirm that maturation has great effect on growth and physical performance measures and the estimated PHV age is an applicable tool in young athletes, mainly aiding professionals in structuring the teaching-learning- training process in this age group.

title: Nutritional status and evaluation of the perioperative fasting time among patients submitted to elective and emergency surgeries at a reference hospital.

description: ABSTRACT Objective: to evaluate the clinical, surgical, and nutritional profile of surgical patients admitted to a reference hospital in Recife city, Pernambuco state, Brazil. Methods: a cross-sectional study carried out in the wards of the General Surgery Service of Hospital da Restauração Governador Paulo Guerra, from June to September 2018. We included adult and elderly patients (both genders) who were submitted to thoracoabdominal procedures and elective or emergency abdominal surgeries, and in which the assessment of nutritional status could be performed within 72 hours of hospital admission. Data on nutritional status and surgical procedures, as well as clinical and biochemical information, were collected. Results: we studied 140 patients with median age of 45 years. Among all, 59.3% were female and 23% malnourished, according to Subjective Global Assessment. The median preoperative fasting time was 15 hours for size I surgeries and 13.5 hours for size II ones. Longer postoperative hospital stay showed a strong correlation with the total length of hospital stay in both surgical sizes. Malnourished patients had a longer period of perioperative fasting and hospital stay when compared to well-nourished patients (p&lt;0.001). Conclusion: the perioperative fasting time for elective surgeries was longer than recommended by literature. Patients with longer fasting spent more time in hospital.

title: Do biological maturity and performance influence the training load of track and field athletes?

description: Abstract It is necessary to clarify if BM and track and field performance can modulate the perception about RPE-session. The purpose of the present study was to verify if biological maturity and track and field-specific performance can be associated with training load (RPE-session method). Seventy-five young athletes (13-15 years old) of both genders participated in the present study. The experimental protocol lasted seven consecutive days. Performance tests (75-m running, long jump, 250-m running, shot put and 1000-m running) were made on the first day. After 48 hours, five days of track and field training it was prescribed, each day represents a training of each performance test. All training sessions had the same duration (120 min). The value of the training load was obtained multiplying the RPE value with training session duration (in minutes). For girls, the training load of 250-m training was correlated with biological maturity (r = -0.36, p = 0.02, n = 37) and specific performance (r = 0.33, p = 0.04, n = 37). All other analyzes indicate that biological maturity and track and field-specific performance do not influence the training load based on RPE-session method. Training load based on RPE-session is not influenced by biological maturity and track and field-specific performance, therefore can be used to control the training load of young track and field athletes. To girls it is necessary a care to control the training sessions intensity of 250-m running.

title: Religious/spiritual coping and spiritual distress in people with cancer

description: ABSTRACT Objective: To investigate the relation between the presence of spiritual distress and use of RSC and sociodemographic, clinical and religious/spiritual variables in people with cancer. Method: Cross-sectional study conducted in an association for support to people with cancer. The data obtained with the tools were analyzed using the Spearman‘s correlation coefficient and the Mann-Whitney Test. Results: 129 volunteers participated in the study, of which 57% showed moderate spiritual distress, 96% used medium and high positive religious/spiritual coping. Spiritual distress showed positive correlation with negative religious/spiritual coping (P&lt;0.001) and inverse correlation with age (p 0.002). The use of positive religious coping was statistically significant in people who have religious practices (p 0.001). Conclusão: Spiritual distress is a phenomenon that is present in the lives of people with cancer and has significant relation with the use, in a negative manner, of religion/spirituality as a way of coping with the disease.

title: WATER VERSUS LACTOSE SOLUTION AS A DISPERSION MEDIUM FOR PARTICLE ANALYSIS IN SWEETENED CONDENSED MILK BY LASER DIFFRACTION

description: Sweetened condensed milk contains various dispersed particles, such as proteins, fats, and lactose, all of which make it highly viscous. During sweetened condensed milk production, microcrystalline lactose is added in order to control the product crystallization. The purpose of this study was to characterize the behavior of commercially sold sweetened condensed milks submitted to laser particle size analysis using two different dispersion media: water and a lactose solution. The lactose solution dispersion medium extended the length of time the sweeten condensed milk samples’ original characteristics were present during the laser diffraction particle sizing measurements that were carried out. Significant difference was observed (p &lt; 0.05) between analysis times when water was used as a dispersing medium versus when a lactose solution was used (p &gt; 0.05). Using a lactose solution as a dispersion medium when determining particle size in sweetened condensed milk prolongs the original characteristics of the sample substance during laser diffraction particle analysis.

title: DEVELOPMENT AND VALIDATION OF METHOD FOR DETERMINATION OF BISPHENOL A AND ETHINYLESTRADIOL IN WATER HYACINTH AND DWARF PAPYRUS FROM CONSTRUCTED WETLANDS

description: Bisphenol A and ethinylestradiol, both considered as endocrine disruptors, have been found in surface water and effluents from municipal wastewater supply and can cause adverse health effects on wildlife species and in human beings at extremely low level. In order to remove these compounds from wastewater, constructed wetlands has been used since it proved to be more efficient, and has less cost than conventional treatments. One of the mechanisms of removal of endocrine disruptors by constructed wetlands is the uptake by macrophytes, so it is necessary to analyze these compounds in the plants of the system. Thus, the objective of this study was to develop and validate two methods by high performance liquid chromatography with fluorescence detector capable of determining these compounds in dwarf papyrus and water hyacinth. The evaluated parameters in the validation were: linearity (R2 ≥ 0.99), limit of detection (LOD = 0.045-0.15 µg g-1), limit of quantification (LOQ = 0.15-1.50 µg g-1), accuracy (recoveries from 83.5 to 119.4%) and precision (intra-day CV ≤ 6.2% and inter-day CV ≤ 5.8%). Samples from a constructed wetland were analyzed and the developed methods showed be suitable for intended purpose.
