Purpose. Exergames purportedly aim to gamify physical activity, achieving both the high engagement rates found in video games and the health benefits derived from regular exercise. therefore, this study sought to verify the influence of the EA® Active Sport 2® game level on heart rate, perceived exertion and future intention to play, affection, and fun. Methods. 28 individuals (19 men and 9 women) aged between 19 and 25 years, students, participated in the study. the volunteers had their body composition measured and completed an exercise preference and tolerance questionnaire. On the second visit, the participants had their resting heart rate measured and, subsequently, underwent a maximum incremental test to determine the ventilatory thresholds. the third and fifth visits tested different exercise intensities (light, moderate and strong) determined by EA Active Sport, for PlayStation 3. to minimise the risk of bias, the sessions were randomised. Heart rate, affection, perceived exertion, motivation and future intention to play were measured in game sessions. Results. During exercise, the mean heart rate (HR) at rest was below the heart rate reserve (HR res ) and the ventilatory threshold 1 (LV1) in low-intensity exercise and in the lower limit of the heavy domain for moderate and Active Game High. the assessment of perceived exertion (RPE) and affection did not show differences between the different intensities of the game. Conclusions. the EA Active Sport 2 differentiates light from moderate and high-intensity exercise, but not between moderate and high game intensities. Affection, RPE, intention to play, and enjoyment did not differ between game intensities.

Purpose.Self-regulation of exercise intensity with the Borg 6–20 scale seems a promising alternative, since the magnitude of effort is regulated by internal factors inherent to the individual and their perception of effort during the activity. In order to verify this hypothesis, some studies have tested the validity of the Borg 6–20 scale for prescribing exercise intensity. The study aim was to review the literature and verify the validity of the Borg 6–20 scale in aerobic exercise prescription.Methods.The PICOS strategy was used to conduct the search for evidence concerning the objectives of the review as recommended by PRISMA-P. The level and quality of evidence were analysed by using the Cochrane Collaboration’s recommendation for systematic reviews.Results.A total of 1434 references were found. After applying the criteria of inclusion, 15 studies were considered eligible for review. These studies generally tested the validity of intensity-regulated prescriptions with rating of perceived exertion (RPE) by comparing physiological and performance measures obtained in incremental tests or conventional prescriptions with the measures generated by prescriptions regulated with the Borg 6–20 scale. In addition, some studies evaluated the reliability and reproducibility of RPE-regulated prescriptions by comparing physiological and performance measures obtained from different intensity-regulated exercise sessions with the Borg 6–20 scale.Conclusions.According to the studies investigated in this systematic review, the recommendation of the Borg 6–20 scale in exercise prescription is not yet a valid alternative to describe similar intensity magnitudes to physiological and performance variables.

ABSTRACT Introduction: Tapering is a decisive phase in planning a young swimmer's preparation for competition. During this period, not only training loads, but also recovery, which includes sleep quality, must be constantly monitored. Objective: This study aims to investigate sleep behavior as a variable directly influenced by training load during the tapering phase of training for young swimmers. Methods: A polysomnography test was performed at the beginning of the tapering phase, as a baseline for sleep variables. In each daily training session, the overload and recovery variables were measured. The internal training load was evaluated in the PSE session and the external load by quantifying the training. The recovery variables were divided into the recovery variable, assessed using the TQR questionnaire, and sleep variables, which included sleepiness, scored using the Karolinska scale, and sleep behavior, using an actigraph and a sleep diary. Conclusion: It is concluded that there is no significant influence between training loads and sleep variables. However, a strong association was observed between TST and EL (External load), in the irregular sleep group. Level of evidence III, Study of behavior.

The purpose of the study was to investigate the effects of passive recovery with self-selected time on affect, ratings of perceived exertion, and heart rate in self-selected interval exercises (SSIE). Fifteen older women (68.1 ± 3.8 years), weekly practitioners of functional activities participated in three SSIE with self-selected recovery time (SSRT) and one self-selected continuous exercise session, all at 24 min approximately. The SSIE had the following configurations: 1′/SSRT, 1.5′/SSRT, and 2′/SSRT. The results showed that at the beginning of stimulus heart rate in 1.5′/SSRT (107.9 ± 16.5) and 2′/SSRT (114.6 ± 17.1) were significantly greater (p < .05) compared with self-selected continuous exercise (102.8 ± 14.5). The ratings of perceived exertion in self-selected continuous exercise (2.4 ± 0.4; p < .05) were higher compared with SSIE in recovery. No significant differences were found in affect. The SSIE provided similar responses based on recoveries manipulations.

This study aimed to verify the effect of exercise recovery time on the affective responses during a circuit training in physical education classes. Forty-six apparently healthy young adolescents (twenty-one girls) (12.85 ± 0.94 years; 49.7 ± 8.93 kg; 1.59 ± 0.08 cm; 19.51 ± 3.28 kg/m2) participated in this study. Were submitted participants for two physical education classes, based on circuited model of the same intensity, but with different recovery times (2 min and 1 min). The study was carried out in two phases: baseline and intervention. Affect, Arousal, and Ratings of Perceived Exertion data were analyzed using paired t-tests, considering a significance level of p < 0.05. The class with longer rest time (2 min) provided greater affection (t(45) = 3.586; p < 0,001) and less perceived effort (t(45) = 2.295; p = 0,026). The intensity manipulation strategy was effective in providing different affective responses, in which classes perceived as more intense, resulting in the decline of affect.

Although the beneficial effects of aerobic training on cardiovascular risk factors are evident, the potential beneficial effect of strength and combined training on these risk factors is controversial. This study aimed to evaluate the effect of aerobic and strength training programmes, performed alone or in combination, on cardiovascular risk factors in sedentary, apparently healthy and non-obese adult men. The study was conducted with 37 subjects who were randomly divided into the following groups: aerobic (AG), combined (ASG), strength (SG) and control (CG). The exercise programmes were performed three times a week and lasted approximately 50 minutes. Dietary intake, anthropometry, blood pressure, muscular strength, aerobic capacity, lipid profile and glycaemic control were assessed before and after 12 weeks of the intervention. One-way analysis of variation (ANOVA) for baseline, and ANOVA for repeated measures were used to assess differences between the initial and final time points of the four groups. Changes in blood pressure and glycaemic control were not significant in any of the groups. No differences were observed in LDL-C between training groups. HDL-C increased significantly only in the AG. In conclusion, if minimal changes in the lipid profile are needed, an aerobic training programme can provide possible benefits for HDL-C in apparently healthy and non-obese adult men.

PurposeHeart rate (HR) monitors have recently started to use photoplethysmography, a technique which measures the light reflected by blood vessels and does not require the use of a chest strap. The aim of this study was to test the validity and accuracy of the Garmin<sup>®</sup> HR monitor, which measures HR at rest and during exercise utilizing the method of photoplethysmography.MethodsThe sample consisted of 28 males aged 18–32 years. Anthropometric measurements were collected and HR was concomitantly monitored with electrocardiography and with the Garmin<sup>®</sup> 735XT<sup>®</sup> device in 2 situations: at rest and during self-selected exercise. Descriptive statistics, linear regression, Bland-Altman plot, mean absolute error (MAE), and mean absolute percentage error (MAPE) were calculated for statistical analysis. Correlations between the HR measurement with electrocardiography and the Garmin<sup>®</sup> monitor at rest and during exercise were obtained (<i>r</i> = 0.93 and <i>r</i> = 0.96, respectively).ResultsThe difference between Garmin<sup>®</sup> and electrocardiography HR values showed an error of –1.2 ± 3.3 bpm (rest), while the average error was positive at 0.7 ± 5.1 bpm. MAE and MAPE at rest equalled 2.2 ± 2.8 bpm and 3.3%, respectively. In addition, MAE and MAPE for exercise were 3.5 ± 3.8 bpm and 3.0%, respectively.ConclusionsThe Garmin Forerunner 735XT can be used at rest, as well as with walking and running activities of light, moderate, and vigorous intensities.

Natural products are continually explored in the development of new bioactive compounds with industrial applications, attracting the attention of scientific research efforts due to their pharmacophore-like structures, pharmacokinetic properties, and unique chemical space. The systematic search for natural sources to obtain valuable molecules to develop products with commercial value and industrial purposes remains the most challenging task in bioprospecting. Virtual screening strategies have innovated the discovery of novel bioactive molecules assessing in silico large compound libraries, favoring the analysis of their chemical space, pharmacodynamics, and their pharmacokinetic properties, thus leading to the reduction of financial efforts, infrastructure, and time involved in the process of discovering new chemical entities. Herein, we discuss the computational approaches and methods developed to explore the chemo-structural diversity of natural products, focusing on the main paradigms involved in the discovery and screening of bioactive compounds from natural sources, placing particular emphasis on artificial intelligence, cheminformatics methods, and big data analyses.

Resumo O objetivo é verificar a associação entre maturação sexual e atividade física na adolescência. Trata-se de um estudo de revisão sistemática elaborado a partir de artigos publicados entre 2008 a 2018 nas bases de dados Medline-PubMed, SciELO, Web of Science, Scopus, Lilacs e Adolec BVS. Utilizou-se os descritores e palavras-chave adolescente, maturação sexual, inquérito, questionário e atividade física, no idioma português e sua equivalência na língua inglesa e foram identificados 806 artigos. Após aplicação dos critérios de seleção foram incluídos 12 artigos. Maior nível da prática de atividade física foi observado em adolescentes em fase de maturação sexual inicial. A evolução do desenvolvimento maturacional sexual parece estar correlacionado à redução dos níveis de atividade física. Os achados não evidenciam um consenso sobre associação entre maturação sexual e nível de atividade física quanto à predisposição direta ou inversa da maturação sexual em relação ao nível de atividade física entre adolescentes. São necessárias mais pesquisas para compreender essa relação e possibilitar aos profissionais envolvidos com a saúde do adolescente agir efetivamente no combate à inatividade física.

BACKGROUND
the aim of the present study was to compare the prevalence of metabolic syndrome in Brazilian children aged 6-10 years between three different international criteria.
METHODS
systolic and diastolic blood pressure (SBP and DBP), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, fasting glucose, and insulin levels were measured in 290 schoolchildren, and the presence of metabolic syndrome was analyzed according to the criteria established by Cook, Boney, and Ferreira.
RESULTS
the prevalences of metabolic syndrome were 2.27 % (Boney and Ferreira criteria) and 7.58 % (Cook criteria) for girls, and 3.8 % (Boney and Ferreira criteria) and 5.06 % (Cook criteria) for boys. Agreement in pairs showed a concordance of 57.5 % (Kappa = 0.57) between Boney and Cook criteria, and 65.2 % (Kappa = 0.65) between Cook and Ferreira. The greatest concordance found was 77 % (Kappa = 0.77) between Boney and Ferreira criteria, demonstrating a substantial agreement.
CONCLUSION
prevalences according to Boney and Ferreira criteria were lower than according to Cook criteria. Therefore, we suggest the use of Cook criteria in clinical practice for the diagnosis of metabolic syndrome, since these criteria provided a wider diagnostic range, thereby reducing the risk of underdiagnosis.

PurposeThe aim of this study was to validate the 3-Day Physical Activity Recall (3DPAR) for measuring daily energy expenditure in children and adolescents.MethodsChildren and adolescents, a total of 148 participants, were recruited in 10 schools. The data collection was carried out in a period of 11 months. The measurements of weight, skinfold, and circumferences were performed. After the anthropometric assessment, an accelerometer was put on and the participant remained with the electrodes during 5 days. On the fifth day, the accelerometer was taken off and 3DPAR was applied. After 1 week of the study (eighth day), 3DPAR was applied again for testing reliability.ResultsIn the analysis of reliability and internal consistency, Cronbach’s alpha was 0.73 for the first assessment of 3DPAR and 0.83 for the second one. The consistency of the values estimated by 3DPAR yielded Cronbach’s alpha of 0.89 in the first assessment and 0.83 in the second one. The correlations and the coefficient of determination between 3DPAR and the accelerometer were considered moderate and significant (<i>r</i> = 0.645, <i>p</i> < 0.001).Conclusions3DPAR presented satisfactory reliability and moderate correlations with the criterion measurement in children and adolescents aged 10–12 years.

Abstract The purpose of this present study was to develop and validate a prediction equation for body composition assessment using anthropometric measures of elderly women. This is cross-sectional correlational study with 243 older women ± 64.5 years old and body mass index (BMI) ± 28.70 kg/m². For the development of the equation it was utilized the method of hold-out sample validation. The participants were randomly divided into equation development group (96 elderly women) and a group for validation (147 elderly women). Total body mass, height, waist and hip circumferences, ratio waist-hip ratio and BMI were measured. The whole-body dual-energy X-ray absorptiometry (DXA) assessed body composition (percentage of body fat, fat mass, and fat-free mass). The equations were developed using multiple linear regression, with validation by the stepwise method; the comparison of the equations was analyzed by the paired Student's t test and the analysis of residual scores by the method of Blant and Altman. The New Equation presents a strong correlation (R = 0.83) and (R² = 0.69), and a standard error of estimation equals to 3.21% for percentage body fat prediction. The mean difference between the estimations of percentage body fat from DXA and the New Equation was 0.11% (t(0,180); P = 0.850). Therefore, the New Equation had an accuracy of 93.5% and a total error of 1.8%. The body fat estimation in older women using this New Equation based on BMI and age is valid and accurate.

Abstract The aim of the study was to compare maximum oxygen uptake, maximum heart rate, speed corresponding to VO2max, time to exhaustion, and ventilatory thresholds between two maximal test protocols (scaled vs ramp) with equalized metabolic demand in apparently healthy young adults. Twenty-seven subjects of both sexes were analyzed and submitted to two maximum tests: 1) scaled test with 1.2 km∙h-1 every 2 min; 2) ramp test with 0.1 km∙h-1 every 0.18 min; both with 1% slope and maximum total duration of twenty minutes. Respiratory gas exchanges were directly analyzed, and ventilatory thresholds determined through visual inspection. Central tendency and dispersion measures were adopted, as well as paired t-test and effect size. Bland-Altman analysis verified the agreement among variables. Maximum speed showed significance difference (p < 0.01) for the scaled test (14.0 ± 1.9 km∙h-1) and ramp test (14.6 ± 2.3 km∙h-1). Even with small BIAS values, negative trend and high limits of agreement could be observed. Despite the non-difference presented for variables, except for maximum speed, it could be concluded that the scaled test is able to determine the analyzed variables similar to the ramp test, considering the same conditions of the present study.

PurposeTo verify the validity of Instant Heart Rate® application in smartphones for the measurement of exercise heart rate.MethodsThe individuals were initially instructed about all the procedures to be performed and signed the consent form. Anthropometric measures and rest heart rate were evaluated before the experimental session of the study. The subjects participated in a self-selected exercise on a cycle ergometer for 10 minutes.ResultsThe results for validity demonstrated in an iPhone/iOS® smartphone revealed the intra-class correlation coefficient of <i>r</i> = 0.87 with a tendency to overestimate the heart rate by 5 bpm. For the Lenovo/Android® model, the intra-class correlation coefficient was <i>r</i> = 0.98, underestimating the values by –0.7 bpm. Thus, both systems presented high correlation values, and the error observed did not seem to compromise the several measures that use heart rate as a parameter.ConclusionsIt is possible to conclude that heart rate monitoring by the Instant Heart Rate® application on iPhone/iOS® and Lenovo/Android® operating system smartphones can be performed safely during exercise, with the Lenovo/Android® base being even more reliable than the iPhone/iOS® system.

ABSTRACT Background: Self-selected exercise intensity (SSEI) promotes higher affect (pleasure) during exercise, but its reliability is still unclear. Purpose: to evaluate the test-retest reliability and the minimum detectable change of the perceptive and physiological responses in two sessions of SSEI on treadmill in elderly women. Method: Twenty elderly women (ages 65.3 ± 4.2 years) performed two 20-min laboratory-based treadmill aerobic exercise sessions with self-selected intensity. During the sessions, %VO2max, %HRreserve, affect, and rating of perceived exertion (RPE) were recorded. Reliability was calculated using the intraclass correction coefficient (ICC) and Bland–Altman plots. The minimum detectable change (MDC) was also calculated. Results: ICC values were 0.98 for % VO2max, 0.83 for % HRreserve, 0.85 for affect, and 0.80 for RPE. No differences were observed in mean values between sessions for all the variables. MDCs were lower than 0.7% for VO2max, 11.7% for HRreserve, 0.7 for affect, and 0.8 for RPE. Bland–Altman plots showed a bias of 0.50% for HRreserve, 3.2% for VO2max, 0.05 for affect, and −0.35 for RPE. Conclusion: Self-selected intensity during aerobic exercise performed on treadmill is reliable, which promotes adequate and lower MDC values on physiological and perceptual responses in elderly women.

Physical activity measurement with accuracy and precision is extremely important in establishing the dose-response relationship between levels of physical activity and the different outcome possibilities. Subjective methods of measurement, such as proxy-reports have been used as a possibility to check physical activity in children. The aim of this study was to test the Netherlands Physical Activity Questionnaire (NPAQ), valid for Brazilian schoolchildren using physical aerobic fitness as a criterion. The study included 290 children aged 6-10 years from public schools of Itaúna/MG. NPAQ was applied to parents or guardians and children were tested using the Luc Léger test. NPAQ had mean score of 25 for children (25 for boys and 24 for girls) and VO2max was 50.8 ml/kg/min for children (52.6 and 50.2 ml/kg/min for boys and girls, respectively). The Spearmam correlation test showed significant correlation (rsho = 0.146; p = 0.013) between NPAQ and VO2max, but the correlation is weak (Kappa -0.14). The results showed that NPAQ presented poor construct validity for physical activity measurement in a Brazilian schoolchildren sample, based on aerobic physical fitness criteria.

ABSTRACT Objective To analyze if aerobic capacity is related to Birth Weight and breastfeeding patterns in boys and girls, products of a term pregnancy and normal weight. Methods A representative sample of 230 Brazilian children (6-10 years old), born at term (after 37-weeks’ gestation) with normal weight (between 2.5 and 4.0kg). These children performed a Yo-Yo Test to estimate their aerobic capacity and mothers reported their children’s Birth Weight and breastfeeding patterns. The Pearson correlation coefficient was used to measure the association between aerobic capacity with Birth Weight and breastfeeding patterns. Results We did not observe any significant associations between aerobic capacity with Birth Weight and breastfeeding time in either sexes (p>0.05). Conclusion These results indicate that aerobic capacity is not related with Birth Weight or breastfeeding time in children born with normal weight and gestational age, suggesting that this complex physiological parameter does not appear to be determined by intrauterine factors that dictate the Birth Weight and breastfeeding patterns in the beginning of life.

Na oferta de uma educacao esportiva de qualidade, o Programa Segundo Tempo (PST) teve a clareza de que um programa para funcionar em escala nacional deveria, alem de construir padroes teoricos e metodologicos minimos para fornecer ensino esportivo de qualidade, implementar um modelo de avaliacao para medir a qualidade do ensino oferecido. Desse modo, o objetivo do presente estudo foi conceber o Protocolo de Observacao de aula (POA), bem como estabelecer sua validade de face e de conteudo. Para a construcao do instrumento foram observadas as seguintes etapas 15 , : a. revisao dos documentos que fundamentam o PST; b. reunioes e consultas as equipes pedagogicas; c. construcao da definicao operacional; d. construcao dos itens; e. estudo piloto (Indice de Concordância entre os observadores ao avaliarem a mesma aula). De uma forma geral, nao foram encontradas divergencias entre as equipes quanto a relevância dos itens e seus ponderamentos. Alem disso, a aplicacao piloto apresentou Indice de Concordância de 0,71 ± 0,22. Desse modo, o POA se mostrou consistente e um excelente balizador para medir a qualidade de entrega das aulas do PST nos nucleos.

RESUMO Introdução: Diversos são os instrumentos que mensuram atividade física no Brasil. Um deles é o Three Day Physical Activity Recall, porém, até o momento, nenhuma ferramenta foi submetida à adaptação transcultural. Objetivo: Descrever os procedimentos e critérios de escolha do Three Day Physical Activity Recall quanto à equivalência conceitual, semântica e de itens, que resultou na versão brasileira para adolescentes de 10 a 12 anos. Métodos: Foram compilados artigos que continham o instrumento de autorrelato, que tivessem como variáveis de interesse o nível de atividade física e o custo energético. As buscas foram realizadas nas bases de dados BIREME, LILACS, MEDLINE, PubMed, SciELO, Web of Science e SPORTDiscus. Seguiram-se as etapas da adaptação transcultural: dez doutores e 30 membros da população-alvo participaram da avaliação e adequação do constructo à cultura brasileira (equivalência conceitual e de itens) e a versão em português do instrumento seguiu todas as recomendações para equivalência semântica. Resultados: São apresentadas as avaliações dos doutores sobre a versão em português do instrumento, envolvendo questões sobre regionalidade das atividades, dificuldade cognitiva para o autorrelato, instruções, capacidade de mensuração da atividade física e seus domínios. As diferentes versões de tradução e re-tradução do instrumento, com destaque para as modificações solicitadas, assim como a versão final são apresentadas. Conclusões: Tendo sido satisfeitos os pré-requisitos da adaptação transcultural, concluiu-se que o instrumento está adaptado para a população e cultura alvo; entretanto, as qualidades psicométricas, a reprodutibilidade, a validade, o constructo e o critério devem ser testados.

The aim of this study was to assess the suitability of body mass index, waist circumference, waist-to-height ratio and aerobic fitness as predictors of cardiovascular risk factor clustering in children. A cross-sectional study was conducted with 290 school boys and girls from 6 to 10 years old, randomly selected. Blood was collected after a 12-hour fasting period. Blood pressure, waist circumference (WC), height and weight were evaluated according to international standards. Aerobic fitness (AF) was assessed by the 20-metre shuttle-run test. Clustering was considered when three of these factors were present: high systolic or diastolic blood pressure, high low-density lipoprotein (LDL) cholesterol, high triglycerides, high plasma glucose, high insulin concentrations and low high-density lipoprotein (HDL) cholesterol. A ROC curve identified the cut-off points of body mass index (BMI), WC, waist-to-height ratio (WHtR) and AF as predictors of risk factor clustering. BMI, WC and WHR resulted in significant areas under the ROC curves, which was not observed for AF. The anthropometric variables were good predictors of cardiovascular risk factor clustering in both sexes, whereas aerobic fitness should not be used to identify cardiovascular risk factor clustering in these children.

Abstract Oxygen uptake (VO2) and heart rate (HR) kinetics after exercise are important indicators of fitness and cardiovascular health. However, these variables have been little investigated in resistance exercise (RE). The current study compared post-exercise kinetics of VO2 and the HR among different types of REs. The study included 14 males (age: 26.5±5.4 years, body mass: 80.1±11.4 kg, body height: 1.77±0.07 m, fat content: 11.3±4.6%) with RE experience. Dynamic muscle strength was measured using one repetition maximum (1RM) with regard to the half-squat, bench press, pull-down, and triceps pushdown exercises. The participants performed a maximum number of repetitions at 80% of 1RM for each exercise, separated by a recovery period of 60 minutes. VO2 was measured using ergospirometry. VO2 and HR kinetics were assessed using the time constant of the recovery curves, and excess oxygen consumption (EPOC) was calculated afterward. Significant differences were not observed across the exercises with regard to VO2 kinetics. However, the half-squat exercise elicited a greater EPOC than the bench press and triceps pushdown exercises (p<.05). HR kinetics was slower for the half-squat exercise than for the other exercises (p<.05). These findings confirm that the type of RE influences both the cardiac autonomic response post-exercise and EPOC, but not VO2 kinetics
