Background: Multicomponent exercise promotes healthy aging, but evidence in community-dwelling older women remains limited. This study examined pre–post changes in functional fitness and cardiovascular health following participation in a six-month multicomponent exercise program. Methods: Thirty-five community-dwelling older women (71.39 ± 6.82 years) participated in a quasi-experimental pre–post intervention study. Participants completed supervised multicomponent exercise sessions twice weekly for six months. Anthropometric, cardiovascular, and functional fitness outcomes were assessed before and after the program. Results: Reductions were observed in body mass (68.03 ± 11.39 vs. 66.29 ± 10.02 kg; p < 0.001) and body mass index (26.56 ± 3.71 vs. 25.90 ± 3.22 kg·m−2; p < 0.05). Lower post-test values were also observed for systolic blood pressure (125 ± 9 vs. 121 ± 10 mmHg; p = 0.026), resting heart rate (85 ± 12 vs. 77 ± 11 bpm; p = 0.008), and double product (10,359 ± 1899 vs. 9701 ± 1705 mmHg·bpm; p = 0.027). Handgrip strength was higher at post-test in both the dominant hand (20.98 ± 5.47 vs. 22.53 ± 6.31 kgf; p = 0.007) and non-dominant hand (19.23 ± 4.99 vs. 21.20 ± 5.61 kgf; p < 0.001). Functional aerobic capacity was also higher at post-test (95.74 ± 21.35 vs. 110.41 ± 22.86 steps; p < 0.001), while flexibility values were higher in the left Chair Sit-and-Reach Test (−15.92 ± 10.48 vs. −12.97 ± 10.91 cm; p = 0.001) and left Back Scratch Test (−3.65 ± 6.82 vs. 4.32 ± 7.83 cm; p < 0.001). Conclusions: Participation in a twice-weekly multicomponent exercise program for six months was associated with favorable pre–post changes in functional fitness and cardiovascular health in community-dwelling older women.
Background: Running-related injuries are a common issue among recreational runners and may affect training continuity and long-term participation. However, injury-associated factors remain unclear due to methodological heterogeneity and reliance on self-reported data. Objective: This study aims to determine the prevalence and anatomical distribution of running-related injuries and their association with physiological characteristics and weekly running volume in recreational runners. Methods: A cross-sectional study was conducted with 98 recreational runners (57 men and 41 women). Women were aged 41.54 ± 9.14 years, weighed 59.55 ± 5.89 kg, and had a maximal oxygen uptake (V.O2max) of 43.24 ± 4.86 mL·kg−1·min−1, whereas men were aged 40.16 ± 8.85 years, weighed 80.50 ± 12.89 kg, and had a V.O2max of 47.73 ± 7.55 mL·kg−1·min−1. Running-related injuries during the previous 12 months were clinically confirmed. Sex, age, body composition, V.O2max, resting heart rate, and weekly training volume were analyzed using independent t-tests and multivariable logistic regression. Results: Running-related injury prevalence was 43.9% (women: 56.1%; men: 35.1%), with a significant association between sex and injury occurrence (Fisher’s exact test, p = 0.043). The knee was the most frequently affected anatomical region, followed by the leg and ankle/Achilles regions. Iliotibial band syndrome was the most common diagnosis, followed by calf muscle injury, Achilles tendinopathy, plantar fasciopathy, ankle sprain, and hip labral tear. None of the demographic or physiological variables investigated, including weekly running volume, were independently associated with injury occurrence, and the model explained only a small proportion of the variability in injury occurrence. Conclusions: Running-related injuries were frequent among recreational runners, with knee-related injuries representing the most common anatomical pattern and iliotibial band syndrome being the predominant diagnosis. Although female runners presented a higher injury prevalence, the multifactorial nature of running-related injuries was reinforced, as the investigated demographic and physiological characteristics, along with weekly running volume, showed limited explanatory capacity for injury occurrence.
OBJECTIVES:To compare the acute response of moderate intensity continuous exercise (MICE) vs moderate intensity interval exercise (MIIE) on endothelial function, post-exercise hypotension (PEH), and glycemia in type 2 diabetes (T2DM) with hypertension. METHODS:Twelve T2DM (aged 52.8 ± 3.8 years old) patients with hypertension underwent a randomized cross-over study following isocaloric (200 kcal) protocols: (i) MICE: walk-jogging at 50% of VO2peak, (ii) MIIE session: walking - jogging (stimulus/recovery - 3:3 min each) at 60% of VO2peak followed by recovery at 40% of VO2peak, and (iii) control (CON): lying quietly in a supine position for 30 min. A generalized estimating equation was utilized to verify possible differences over time × session. RESULTS:The %FMD (Baseline: 3.59 ± 1.58 vs. 30 min: 6.73 ± 4.34) and the absolute FMD changed after MIIE (Baseline: 0.16 ± 0.10 vs. 30 min: 0.17 ± 0.14). Only absolute FMD changed after MIIE (Baseline: 0.14 ± 0.07 vs. 30 min: 0.16 ± 0.07). Besides, MIIE at 30 min provides higher absolute FMD values when compared to baseline from MICE and baseline, 30 min, and 60 min from control. Regarding blood pressure, no PEH statistical main effect was found. Finally, the glycemia changed at baseline vs. 30 min and 60 min after MIIE (210.5 ± 9.4 vs. 127.6 ± 10.0 and 120 ± 8.9), MICE (219.5 ± 12.7 vs. 125.2 ± 12.0 and 118.2 ± 11.6), and control sessions (215.9 ± 11.8 vs. 187.4 ± 11.2 and 172.6 ± 11.3 mg/dL, p < 0.05). However, MIIE and MICE showed higher decreases compared to the control. CONCLUSIONS:MIIE and MICE sessions are similar and effective exercise strategies to induce changes in endothelial function and glycemic responses in type-2 diabetics with hypertension.
Several conditioning indicators are necessary when performing running events, such as: the ability to sustain speed during a test and obtain good competitive rates in medium and long distance events. Purpose: This systematic review was to verify the distribution of weekly training volume during the preparatory phase of recreational runners and analyse the effect of this volume on maximum oxygen consumption and time-trial running. Results: The seven studies included analysed the training volume effect. A total of 120 adult participants were included with age of 27.80 ± 5.52 years, VO2 of 47.45 ± 7.82 ml/kg/min-1. All presented different aerobic training methods: HIIT, undulatory training, Linear, Reverse and Sprints. The interventions had an average duration of 10.00 ± 3.57 weeks. Training volume at the beginning of the interventions of 30 ± 7.21 km/week. A total of 59 adult participants with experience in road running and with performance in the 10 km and 1 km distances of 44.22 ± 8.43 min and 5.17 ± 0.24 min. Conclusion: The present review indicates that adjustments in training volume, specifically increments of up to 42% during the preparatory phase, can produce significant improvements in VO2max and time trial performance.
Introdução: A posição tática no futebol requer demandas diferentes de trabalho, contudo, não tem sido investigada em função das dimensões morfológica e metabólica conjuntamente nas categorias de base. Objetivo: Comparar características antropométricas, de composição corporal e metabólicas de jogadores juniores de futebol conforme a posição tática. Materiais e Métodos: Em um estudo transversal, 26 futebolistas do sexo masculino da categoria juniores (15-18 anos) realizaram medidas antropométricas e testes de capacidade anaeróbia (Wingate) e de potência aeróbia (ergoespirometria). Um modelo robusto univariado (p<0,05) e o d de Cohen foram empregados na comparação das posições táticas. Resultados: Goleiros foram mais altos que laterais (p=0,033), meio-campistas (p=0,007) e atacantes (p=0,035). Adicionalmente, zagueiros foram mais altos que meio-campistas (p=0,031). Foram observados tamanhos de efeito pequenos a muito grandes da posição tática para as variáveis antropométricas e de composição corporal (0,54 ≤ d ≤ 2,10). Os laterais apresentaram maiores valores relativos V̇O2 comparados aos atacantes (p=0,008) e aos goleiros (p=0,042). O V̇O2 no limiar anaeróbio dos laterais também foi superior comparados aos atacantes (p=0,008) e aos goleiros (p=0,042). Foram observados tamanhos de efeito moderados a grandes da posição tática para as variáveis da ergoespirometria (1,18 ≤ d ≤ 1,76) e pequenos a grandes para as variáveis do teste de Wingate (0,37 ≤ d ≤ 1,10). Conclusão: O efeito das posições táticas em algumas variáveis antropométricas e metabólicas sugerem uma acentuada especialização de goleiros e laterais.
Introduction: Playing position in football requires different work demands, however, it has not been investigated in relation to the morphological and metabolic dimensions together in junior football players. Aim: To compare the anthropometric, body composition, and metabolic characteristics of young football players according to the playing positions. Material and Methods: In a cross-sectional study, 26 young male football players (15-18 years) underwent anthropometric measurements, besides anaerobic (Wingate) and aerobic power (ergospirometry) tests. A robust univariate model (p<0,05) and Cohen's d were used to compare the playing positions. Results: Goalkeepers were taller than wingback (p= 0.033), midfielders (p=0.007), and forwards (p=0.035). In addition, defenders were taller than midfielders (p=0.031). Small to very large playing position effect sizes were observed for anthropometric and body composition variables (0.54 <= d <= 2.10). The wingback players presented higher relative (V)over dotO(2) values compared to forwards (p=0.008) and goalkeepers (p=0.042). In turn, the (V)over dotO(2) at the anaerobic threshold of the wingbacks was also superior compared to forwards (p=0.008) and goalkeepers (p=0.042). Moderate to large effect sizes were observed for the playing position in the ergospirometry variables (1.18 <= d <= 1.76) and small to large in the Wingate test variables (0.37 <= d <= 1.10). Conclusion: The effect of the playing position on some anthropometric and metabolic variables suggests a marked specialization of the goalkeepers and wingback.
Introducción. El ejercicio interválico de alta intensidad es un método de entrenamiento que se ha popularizado, según el American College of Sports Medicine. De acuerdo con la tradición, verificamos el uso predominante de ergómetros (cintas de caminar y ergómetros de ciclismo) durante sesiones de ejercicio interválico. Sin embargo, el ejercicio con cuerdas de batalla (battle ropes) representa una alternativa a otras modalidades de actividad física. Objetivo. La finalidad de este estudio es comparar la frecuencia cardíaca pico y el consumo de oxígeno durante un ejercicio interválico en esprint con una cuerda de batalla, usando distintas estrategias de ejecución (oscilaciones simultáneas y alternas). Materiales y métodos. Ocho universitarios varones (24.9 ± 7,0 años, 25.2± 3.6 kg/m2 y 38.9 ± 3.4 ml.kg-1.min-1) sin experiencia en la práctica de ejercicios con cuerdas de batalla se sometieron a dos sesiones experimentales distintas: con uso simultáneo y alterno de los brazos en un orden aleatorio y 4 tandas de 30 s a toda potencia (con 4 min de recuperación pasiva). Aplicamos análisis bidireccional con una significancia de p < .05 para el análisis entre grupos. Resultados. El pico de consumo de oxígeno medio obtenido durante cuatro tandas con brazos alternos y simultáneos fue de 76.52 ± 12.71 % y 79.58 ± 15.58 % respectivamente. La frecuencia cardiaca media pico alcanzada durante las cuatro tandas de alta intensidad fue de 85.15 ± 7.10 % y 88.29 ± 5.14 %, respectivamente. Conclusión. Estos datos demuestran que no existe diferencia en la respuesta cardiovascular aguda del ejercicio de protocolo con cuerdas de batalla en las distintas modalidades (brazos alternos o simultáneos). Dichos resultados sugieren que la intensidad generada durante el ejercicio con cuerdas de batalla puede ser suficiente para mejorar y mantener la captación de oxígeno en las personas sanas.
INTRODUCTION: It has been suggested that recovery mode may contribute to performance during high-intensity interval exercise. However, there is no consensus regarding the effects of active and passive recovery modes on subsequent performance. The aim of this study was to compare the effect of active versus passive recovery on performance during repeated high-intensity interval exercise.EVIDENCE ACQUISITION: Two reviewers independently conducted a search using the PRISMA systematic approach in three electronic databases (PubMed, Scopus and Cochrane Central) searching for randomized controlled trials (RCTs) comparing the effects of recovery mode on performance (until February 2020).EVIDENCE SYNTHESIS: Twenty-six studies were included for analysis (17 for power output, nine for repeated-sprint ability and two for distance covered). Four studies found higher mechanical performance for passive recovery compared with active recovery. Six out of nine studies reported faster sprinting performance with passive recovery compared to active recovery. Two studies demonstrated that passive recovery resulted in a greater distance covered during intermittent sprint exercise.CONCLUSIONS: This systematic review suggests that performing high-intensity interval exercise with passive recovery results in greater performance when compared with active recovery.
The confinement period caused by the SARS-COV2 pandemic is another barrier to the practice of physical exercise by people with spinal cord injury (SCI). In view of the countless therapies targeted at this public, it is necessary to highlight the benefits of exercises performed at home. Thus, our objective was to determine the main characteristics of physical exercise training modes performed at home and their effects on people with SCI. We searched for intervention studies in five databases (PubMed, ScienceDirect, SPORTDiscus, Scopus and Cochrane CENTRAL) by including the terms and descriptors: “spinal cord injury”, “home-based”, exercise”, “video game”, “home-based physical activity”. The selected studies were described by means of a narrative synthesis. Of 69,843 studies, only 10 met the eligibility criteria, totaling 153 investigated individuals (25 women and 128 men). Regarding the type of injury, 118 participants were paraplegic and 33 tetraplegic. The studies addressed functional electrical stimulation (n = 4), electronic assistive devices (n = 5) and stretching exercises (n = 1). We observed that the focus of the interventions was the morphological, motor neuron, quality of life and functional aspects. The studies showed improvements in muscle strength and morphology, in the ability to perform daily activities, in quality of life and in functional capacities, with no reported adverse situations. Although our review included a low number of randomized studies, we can conclude that several modes of exercise in the home environment promote benefits for people with SCI and can be options for maintaining or developing the health of this population.
Resumo Fundamento O exercício aeróbio contínuo (EC) é uma das principais recomendações não farmacológicas para prevenção e tratamento da hipertensão arterial sistêmica. O EC é seguro e eficaz para reduzir a pressão arterial cronicamente, assim como nas primeiras horas após sua realização, fenômeno conhecido por hipotensão pós-exercício (HPE). O exercício intervalado (EI) também gera HPE. Objetivo Essa revisão sistemática e metanálise buscou comparar a magnitude da HPE entre o EC e EI em adultos. Métodos Realizou-se uma revisão sistemática de estudos publicados em revistas indexadas nas bases PubMed, Web of Knowledge, Scopus e CENTRAL até março de 2020 que compararam a magnitude da HPE entre o EC versus EI. Foi definida HPE entre 45 e 60 minutos pós-exercício. As diferenças entre grupos sobre a pressão arterial foram analisadas por meio do modelo de efeito aleatório. Os dados foram reportados como diferença média ponderada (WMD) e 95% de intervalo de confiança (IC). Valor p menor que 0,05 foi considerado estatisticamente significativo. A escala TESTEX (0 a 15) foi usada para verificação da qualidade metodológica dos estudos. Resultados O EI apresentou HPE de maior magnitude sobre a pressão arterial sistólica (WMD: -2,93 mmHg [IC95%: -4,96, -0,90], p = 0,005, I2 = 50%) e pressão arterial diastólica (WMD: -1,73 mmHg [IC95%: -2,94, -0,51], p = 0,005, I2 = 0%) quando comparado ao EC (12 estudos; 196 participantes). A pontuação dos estudos na escala TEXTEX variou entre 10 e 11 pontos. Conclusões O EI gerou HPE de maior magnitude quando comparado ao EC entre 45 e 60 minutos pós-exercício. A ausência de dados sobre eventos adversos durante o EI e EC nos estudos impede comparações sobre a segurança dessas estratégias. (Arq Bras Cardiol. 2020; 115(1):5-14)
Introduction: High-intensity interval exercise is a training method that has been popular according to the American College of Sports Medicine. Traditionally, we verified the predominant usage of ergometers (treadmills and cycle ergometer) during interval exercise sessions. However, battle ropes exercise are a alternative to other exercise modalities. Purpose: The aim of the study was to compare heart rate (HR) peak and oxygen consumption (VO2) peak during a sprint interval exercise (SIE) with a battling rope (BRP), using different execution strategies (simultaneous and alternate oscillations). Materials and Methods: Eight college men (24.9 +/- 7.0 years, 25.2 +/- 3.6 kg/m(2), and 38.9 +/- 3.4 ml.kg(-1).min(-1)) having no experience with battling rope exercises completed two different experimental sessions: simultaneous and alternating arms in a random order, and a 4 x 30 s all out (4 min of passive recovery). We used two-way analysis of variance with a significance of p<.05 for the analysis between groups. Results: The average oxygen consumption peak (VO2 peak), obtained during the four bouts of alternating and simultaneous arms was 76.52 +/- 12.71 % and 79.58 +/- 15.58 %, respectively. The average HR peak reached during the four high-intensity bouts was 85.15 +/- 7.10 % and 88.29 +/- 5.14%, respectively. Conclusion: These data show that there is no difference in the acute cardiovascular response of battling rope protocol exercise involving different modes (alternate or simultaneous). These results suggest that the intensity generated during BRP exercise can be sufficient to improve and maintain maximal oxygen uptake in healthy people.
Background: Continuous aerobic exercise (CE) is one of the main non-pharmacological recommendations for hypertension prevention and treatment. CE is safe and effective to reduce blood pressure chronically, as well as in the first few hours after its performance, a phenomenon known as post-exercise hypotension (PEH). Interval exercise (IE) also results in PEH. Objective: This systematic review and meta-analysis sought to compare the magnitude of PEH between CE and IE in adults. Methods: A systematic review of studies published in journals indexed in the PubMed, Web of Knowledge, Scopus and CENTRAL databases was performed until March 2020, which compared the magnitude of PEH between CE and IE. PEH was defined as between 45-60 minutes post-exercise. The differences between groups on blood pressure were analyzed using the random effects model. Data were reported as weighted mean difference (WMD) and 95% confidence interval (CI). A p-value <0.05 was considered statistically significant. The TESTEX scale (0-15) was used to verify the methodological quality of the studies. Results: The IE showed a higher magnitude of PEH on systolic blood pressure (WMD: -2.93 mmHg [95% CI: -4.96, -0.90], p = 0.005,12 = 50%) and diastolic blood pressure (WMD: -1,73 mmHg [IC95%: 2,94, -0,51], p= 0.005, I-2 = 0%) when compared to CE (12 studies, 196 participants). The scores of the studies on the TEXTEX scale varied from 10 to 11 points. Conclusions: The IE resulted in a higher magnitude of PEH when compared to CE between 45 and 60 minutes post-exercise. The absence of adverse event data during IE and CE in the studies prevents comparisons of the safety of these strategies.
Objective: To compare intensity (heart rate, oxygen consumption, and perceived exertion) and motivation to play between AVG types (unstructured, UNS-AVG and structured, S-AVG).Methods: A Pre-test-Post-test experimental study with randomized counterbalanced groups (UNS-and S-AVG type) was performed at the laboratory.Eight male young adults [Mean (SD), age: 19(1) years, body mass index: 23.1(2.4)kg/m²] volunteered to participate in this study.Participants underwent a diagnostic evaluation for health status, anthropometric, cardiovascular and metabolic measures.After this, they were paired according to oxygen consumption levels and randomly assigned to each group and performed a 30-min AVG session (UNS-AVG: Kinect Sports Boxing game or S-AVG: Nike Kinect Training game).Heart rate (HR) was recorded during all AVG session.At the end of the session, motivation to play and rating of perceived exertion (RPE) were self-reported.Oxygen consumption estimated for the AVG session was obtained by linear regression line from HR reached during the game and maximal HR during the test session.Unpaired t-test was used to compare game type groups (P<0.05).Moreover, effect size (ES) was calculated using Cohen's d statistic.Results: Average HR (%Δ=7.1,P=0.025, ES=0.76) and oxygen consumption estimated (%Δ=69.5, P=0.002, ES=3.63) during the sessions were greater for S-AVG compared to UNS-AVG.Motivation to play was similar between groups (%Δ=18.2,P=0.685, ES=0.72).RPE was greater for S-AVG compared to UNS-AVG group (%Δ=20.6,P=0.045, ES=1.85). Conclusion:S-AVG type requires more physical exertion than UNS-AVG; however, these AVG types can be used interchangeably if the goal is motivation.Due to the strong correlation between the HR and oxygen consumption for both AVG types, this data suggests that S-AVG may be a better tool to exercise and probably contribute to reducing sedentary lifestyle more than UNS-AVG in young adults.
Artes marciais são formas tradicionais de treinamento, que incorporam técnicas de defesa e ataque. Sua prática contínua e sistematizada proporciona benefícios significativos em torno dos componentes de aptidão física e saúde. O objetivo do estudo foi examinar as implicações da exposição ao treinamento de Aikido durante seis semanas nas variáveis hemodinâmicas e de composição corporal em adultos jovens. Trata-se de um estudo descritivo com foco transversal, realizado com seis sujeitos (28,17 anos) que realizaram um programa de treinamento com a arte marcial Aikido, durante seis semanas (três sessões semanais). Verificou-se as variáveis hemodinâmicas (frequência cardíaca e pressão arterial) e de composição corporal (dobras cutâneas e percentual de gordura) pré e pós-intervenção. Foi utilizado o teste t Student para realizar comparações entre os momentos do estudo. De acordo com os resultados verifica-se que o programa de treinamento com a arte marcial Aikido foi eficiente em causar reduções significativas em torno do percentual de gordura (11,17 – 10,27), pressão arterial diastólica (80,00 – 65,00 mmHg) e frequência cardíaca (125,50 – 106,33 bpm) de repouso.
Introdução: O consumo máximo de oxigênio é uma variável que apresenta associação com a performance esportiva dos atletas. Seus valores podem ser diferentes de acordo com a posição tática. Objetivo: O objetivo do presente estudo foi comparar a potência aeróbia máxima de jogadoras de futebol de acordo com suas diferentes posições do sistema de jogo. Materiais e métodos: Participaram do estudo 18 atletas de futebol do sexo feminino (três zagueiras, quatro laterais, cinco meio-campistas e seis atacantes), com idade média de 19,1 (1,4) anos. Trata-se de um estudo de corte transversal. Foram realizadas as avaliações antropométricas (massa corporal e estatura) e da potência aeróbia máxima (Yo-yo test). Resultados: De acordo com a comparação realizada, não houve diferença estatisticamente significante sobre a potência aeróbia máxima das atletas. Conclusão: Não foram identificadas diferenças significativas quanto ao consumo máximo de oxigênio entre as jogadoras de futebol profissional, independentemente das posições de jogo.
Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those parameters. This is a systematic review with meta-analysis, which searched the databases and data portals PubMed, Web of Science, Scopus, Science Direct and Wiley until December 2016 (pairs). The following terms and descriptors were used: "heart recipient" OR "heart transplant recipient" OR "heart transplant" OR "cardiac transplant" OR "heart graft". Descriptors via DeCS and Mesh were: "heart transplantation'' OR "cardiac transplantation". The words used in combination (AND) were: "exercise training" OR "interval training" OR "high intensity interval training" OR "high intensity training" OR "anaerobic training" OR "intermittent training" OR "sprint training". The initial search identified 1064 studies. Then, only those studies assessing the influence of HIIT on the post-HTx period were added, resulting in three studies analyzed. The significance level adopted was 0.05. Heart transplant recipients showed significant improvement in VO2peak, heart rate and peak blood pressure in 8 to 12 weeks of intervention.
Objetivo: Examinar a objetividade e concordância entre a percepção subjetiva de esforço (PSE-Borg 6-20) e a frequência cardíaca em diferentes jogos de VGA’s. Materiais e Métodos: Participaram do estudo oito estudantes adultos jovens (21 ± 1,6 anos) que realizaram uma sessão VGA’s randomizada com medidas da FC e PSE no 5º e 10º minuto. O teste t student para amostras dependentes foi utilizado para comparar as respostas da PSE (imediata e acumulada) e os valores de frequência cardíaca em cada jogo (5º e 10º minutos). Para análise de concordância foi utilizada a plotagem de Bland-Altman. Realizou-se uma análise de correlação entre cada ponto da PSE e seu respectivo correspondente da FC. O cálculo do tamanho do efeito proposto por Hedges (g) foi utilizado para verificar a magnitude das correlações. Resultados: Foram observadas diferenças significantes para a medida imediata (5º minuto) apenas na Dança. A escala de Borg foi objetiva no boxe e vôlei (5º e 10º minutos) e no 5º minuto para o tênis de mesa e 10º minuto na dança. A magnitude dos efeitos variou de d: 0,13 a d: 0,60. Conclusão: A PSE e FC podem ser utilizadas no controle da intensidade em jogos de vídeo games ativos por apresentarem objetividade e concordância. Porém, nos jogos de tênis de mesa e dança, devem ser utilizados com maior parcimônia face ao viés observado nos diferentes tempos. ABSTRACT Perception subjective effort and frequency heart may be sufficient in intensity control effort in active video games Objective: To examine the objectivity and consistency between the perceived exertion (PSE-Borg 6-20) and heart rate in different VGA's games. Materials and Methods: The study included eight young students (21 ± 1.6 years) who underwent a VGA's random session with measures of HR and PSE at 5 and 10 minutes. The test t student for dependent samples was used to compare the responses of the PSE (immediate and cumulative) and the values of heart rate in each game (5 and 10 minutes). For concordance analysis was used Bland-Altman. We conducted a correlation analysis between each point of the PSE and its corresponding respective HR. The calculation of the size of the proposed effect by Hedges (g) was used to analyze the magnitude of the correlations. Results: Significant differences were observed for immediate action (5 minutes) only in dance. The Borg scale was objective in boxing and volleyball (5 and 10 minutes) and 5 minutes for the table tennis and 10. minute dance. The magnitude of the effect varied from d: 0,13 - d: 0,60. Conclusion: PSE and FC can be used to control video games intensity game assets for presenting objectivity and concordance. But in tennis table and dance should be used more sparingly against the bias observed in different times.
Abstract Objectives To investigate how quickly active video games, structured and unstructured, provide changes in hemodynamic variables in young adults during a 6-week intervention. Method Twenty participants after baseline assessments, participants were randomized: structured active videogame (n = 6), unstructured active videogame (n = 7) and a control group (n = 7). Participants played their respective active videogame 3 times a week for 6-weeks (30 min-session). Results Structured active videogame in exactly 6 weeks shown improvements reducing the heart rate (heart rate; 14% of variation; p < 0.05). Otherwise, not confirmed to both active videogame interventions in systolic blood pressure but maintain the diastolic blood pressure during these 6 weeks (systolic blood pressure-unstructured: −2% and Structured: 11%; diastolic blood pressure-unstructured: 0% and structured: 0%; p > 0.05). Conclusions The 6-week training program with active videogame reduced the heart rate (structured – 6th week). However, active videogames generally do not promoted benefits for normotensive young adults.
Purpose: The aim of the study is to compare the effect of resistance training volume on inhibitory control in young adults with previous experience in resistance training. Method: All the 27 participants underwent 40-week experiment, divided in three training phases of 8-week duration. A washout period of 8 weeks between each of the training phases was carried out. The participants performed 1, 3, or 5 sets of the same exercises with equalized intensity (loading zones) and rest. Inhibitory control was assessed by the Stroop Test. Results: Interaction effect was found for inhibitory control accuracy [F(5,22) = 56.88, p < 0.01] and mean response time [F(5,22) = 83.02, p < 0.01] for 3 sets (p = 0.01; ES = 0.6) and 5 sets (p = 0.01; ES = 0.8) when compared to 1 set. Conclusion: In conclusion, 1 set of resistance training may provide insufficient volume stimulus for positive adaptation in inhibitory control when compared to 3 or 5 sets.
