title: Anthropometric indicators associated with hypertriglyceridemia in the prediction of visceral fat

description: The accumulation of visceral fat is strongly associated with cardiometabolic changes. Alternative methods, such as the association between anthropometric indicators and hypertriglyceridemia, are used as the best estimate for the accumulation of visceral fat, preventing cardiovascular diseases. The aim of this study was to evaluate the association of anthropometric indicators with hypertriglyceridemia in the prediction of visceral fat in men and women. This was a cross-sectional study conducted with 192 individuals, of both genders, submitted to anthropometric evaluation (sagittal abdominal diameter [SAD], waist circumference [WC], and waist-hip ratio [WHR]), serum dosage of triglycerides (TG), and computed tomography scan, in order to measure the visceral adipose tissue (VAT) area. Descriptive analysis, Pearson's Correlation, and multiple linear regression were performed. Anthropometric indicators had high correlation with the VAT area (p=0.000). Regardless of serum TG levels, individuals with high values of anthropometric indicators had excess VAT area (p&lt;0.05). For every centimeter increased in SAD, there was an average increase of 12.46 cm² in the VAT area. The study showed that both SAD and WC were good indicators to explain the variability in the VAT area, independently of changes in TG levels, making it possible to identify individuals with a risk of developing cardiovascular diseases.

title: Anthropometric reference values for community-dwelling older adults from northeastern Brazil

description: The aging process is continuous and irreversible and is characterized by physiological and structural alterations and changes in body composition. The aim of this study was to report anthropometric reference values for community-dwelling older adults from northeastern Brazilaccording to gender and age group. This cross-sectional study used data from an epidemiological population-based study involving 316 older adults. The following measures and anthropometric indicators were evaluated: weight, height, body mass index (BMI), triceps skinfold (TSF), waist circumference, arm circumference, calf circumference, and arm muscle circumference (AMC). All data are reported as means, standard deviations, and percentiles. Comparisons between age groups were performed using one-way ANOVA. The study included 173 women (54.7%) and 143 men (45.3%). Body weight and BMI were higher in younger women (60-64 years) compared to older ones (80 years or older). Arm circumference, TSF and AMC were lower in women aged ≥ 75 years compared to women aged 60-64 years. For men, arm circumference and AMC were lower in the oldest age group (≥ 80 years) compared to the youngest group (60 to 74 years). These differences were significant. The present study indicates that changes in body measures occur differently between genders with advancing age. The reduction in muscle mass and body fat is more prominent in women than in men and anthropometric changes are more noticeable in the older age group.

title: Use of sample size calculation in scientific research in Brazilian Physical Education journals

description: The mistaken use of biostatistics in scientific research involves methodological errors both in the research itself as in its analyses. Among these, the lack of sample size calculation, considered essential for validation and credibility of results, is often found. The aim of the study was to determine how often sample size calculation is used in articles published in Physical Education national journals. The study included only national scientific journals ranked as A1 and B2 by the Coordination of Improvement of Higher Education Personnel (CAPES), which analyzed only articles available in full and published in the period from 2010 to 2012. Review articles, letter to the editor, points of view and original articles that did not perform any statistical analysis were excluded. Approximately 15 % of articles analyzed performed sample size calculation and no difference between these proportions over the years were identified. Differences between Physical Education subareas (education, health and sport) were observed, being lower in sport (p = 0.001) compared to other subareas. Journals classified as B2 showed higher use of sample size calculation in relation to those classified as B1 (p = 0.013) and A2 (p = 0.007). The use of sample size calculation in scientific research published in Physical Education national journals in the period from 2010 to 2012 was not satisfactory, especially in sport subarea. Moreover, no evolution on the use of sample size calculation over the years analyzed was observed.

title: Effects of resistance exercise versus combined training on post-exercise hypotension in women with metabolic syndrome

description: The aim of the present study was to analyze the response of systolic (SBP) and diastolic (DBP) blood following three experimental sessions: resistance exercise (RE), combined exercise (COMB-aerobic and RE) and control session (CON). Thirty women with metabolic syndrome (MS) were randomly assigned to one of three experimental groups: RE (n=10; 36.1 ± 9.0 years) (3 sets of 8-12 repetitions at 80% of 10RM in six exercises for whole body); COMB (n=10; 33.1 ± 5.0 years) (30 min of aerobic exercise at 65-70% of reserve heart rate which was followed by the same RE session) and CON (n=10; 30.4 ± 6.6 years). The SBP and DBP were measured before and every 15 min during 60 min following the experimental sessions. The COMB group presented greater delta SBP (ΔSBP) decrease at 15, 30 and 45 min post-exercise as compared with CON group (p &lt;0.05); the RE group presented greater ΔSBP reduction at 30 and 45 min post-exercise also compared with CON group (p &lt;0.05). In addition, the area under the curve of ΔSBP for COMB group (~30 mmHg of hypotension during 60 min, p ≤ 0.0005) and RE group (~19 mmHg of hypotension during 60 min, p = 0.024) were greater than the CON group. Therefore, RE and COMB elicited post-exercise hypotension in women with MS; COMB provided a greater decrease which may be of value in the prevention and treatment of cardiovascular disorders.

title: Acute effect of a grape concentrate intake on oxidative stress markers in triathletes

description: The aim of this crossover study was to evaluate the effect of a grape concentrate (test drink [TD]) on oxidative stress markers (thiobarbituric acid reactive substances [TBARS], catalase [CAT], superoxide dismutase [SOD], and glutathione [GSH]). Six triathletes had their physical fitness, body fat composition (�) and food intake evaluated. Afterwards, the athletes received two doses of 300 mL of the TD (45.8g of polyphenols/kg) or a placebo drink (PL), at breakfast and after a training session (100 km of cycling, 6 km of running and 1.5 km of swimming). Blood samples (5 ml) were collected after an overnight fasting, immediately after exercise, and one hour after exercise. The triathletes presented the following characteristics (mean and standard-deviation): 43.8±10.2 years old, VO2máx 45±5.15 mL/kg/min, � 13.6±4.2 %, training 270.8±87.1 km/week, 3.1±1.88 hours/training/day. There was a significant increase in SOD from the 1st to the 2nd (p=0.027) and 3rd (p=0.02) blood tests, in response to exercise, regardless of the drink consumed. One hour after exercise, the increase in glutathione values was greater when the PL was consumed (27.5%) in relation to the TD intake (1.8%). In both tests, exercise increased TBARS values; however, when PL was consumed, subjects' values were higher (PL=2.5±1.1 nmol/ml vs. BT=1.77±1.3 nmol/ml). When PL was consumed, mean CAT values (BT=34.2±6.9 U/mgHb vs. PL=24.6±12.5 U/mgHb) reduced from the 1st to the 2nd blood test (28.6%). TBARS, CAT and GSH values suggest that the TD presents potential to modulate exercise-induced oxidative stress.

title: The influence of match status on attacking patterns of play in elite soccer teams

description: The attacking performance in elite soccer is a complex process that is influenced by several situational variables, such as match status. The objective of this study was to investigate the influence of match status on the configuration of attacking patterns of play performed by elite soccer teams based on the analysis of matches played by the semi-finalists of the 2010 FIFA World Cup. We observed 28 matches, 7 per semi-finalist team of the 2010 FIFA World Cup, resulting in 1938 attacks, further ordered according to match status (winning, drawing or losing). The SoccerEye observational instrument, SoccerEye recording software (version 3.2), and SDIS-GSEQ analysis software (version 5.1) were used. The national teams of Germany, Netherlands and Uruguay showed more difficulty in scoring goals while losing the match, although they scored after a positive crossing or after a free kick committed by the opposing team. The national team of Spain tended to shoot into the opponent goal after short passing, in both losing and winning situations. We conclude that attacking patterns of play were influenced by match status in the 2010 FIFA World Cup, with the exception of Spanish national team, which tended to use an indirect style of play with no dependence on match status.

title: Gymnasts and non-athletes muscle activation and torque production at the ankle joint

description: Artistic Gymnasts (AG) execute specific movements that require substantial movement control and force production at the ankle joint. This high demand might change the neuromechanical properties of the ankle joint muscles in these athletes compared to non-athlete girls (NAG). The aim of this study was to compare muscle activation and torque production at the ankle joint between AG and NAG. Ten AG (11.70 ± 1.06 years of age) and 10 NAG (11.70 ± 1.49 years of age) participated in the study. Electromyographic (EMG) signals of medial gastrocnemius (MG), soleus (SO) and tibialis anterior (TA) were obtained simultaneously to the maximal isometric plantarflexion (PFT) and dorsiflexion (DFT) torques of the dominant limb during a maximal voluntary isometric contraction (MVIC) at five different joint angles (20°, 10°, 0°, -10° e -20°). Neuromuscular efficiency was also calculated by the Torque/EMG ratio. AG presented higher PFT (p&lt;0.01) and smaller DFT (p&lt;0.05) at all joint angles compared to NAG. RMS values from the three muscles were similar between groups (p&gt;0.05). In addition, AG showed higher values for plantarflexion neuromuscular efficiency and smaller values of dorsiflexion neuromuscular efficiency compared to the NAG (p&lt;0.01). Higher sports demands of AG determined higher PFT, higher plantarflexor efficiency, smaller DFT but similar activation of MG, SO and TA compared to NAG.

title: Code and data for online beam current estimation in particle beam microscopy

description: In conventional particle beam microscopy, knowledge of the beam current is essential for accurate micrograph formation and sample milling. This generally necessitates offline calibration of the instrument. In this work, we establish that beam current can be estimated online, from the same secondary electron count data that is used to form micrographs. Our methods depend on the recently introduced time-resolved measurement concept, which combines multiple short measurements at a single pixel and has previously been shown to partially mitigate the effect of beam current variation on micrograph accuracy. We analyze the problem of jointly estimating beam current and secondary electron yield using the Cramer-Rao bound. Joint estimators operating at a single pixel and estimators that exploit models for inter-pixel correlation and Markov beam current variation are proposed and tested on synthetic microscopy data. Our estimates of secondary electron yield that incorporate explicit beam current estimation beat state-of-the-art methods, resulting in micrograph accuracy nearly indistinguishable from what is obtained with perfect beam current knowledge. Our novel beam current estimation could help improve milling outcomes, prevent sample damage, and enable online instrument diagnostics. This code reproduces results from paper Figures 6, 7, and 12.
