Effect of 15 consecutive HIIT sessions on the redox State in Wistar rats
Rodrigues, Josimar Camacho; Costa, Roas de Araújo; Aidar, Felipe José; Souza, Raphael Fabrício de; Brito, Ciro José; Santos, Jymmys Lopes dosHigh-intensity interval training (HIIT) can induce oxidative stress. The main aim of this study was to evaluate the effect of 15 sessions of a HIIT protocol in Wistar rats on oxidative damage markers in different tissues (blood, muscle, liver and heart). Thus, animals weighing 250-300g were used and randomly divided into 2 groups (n=10): Control (CG) and animals submitted to HIIT (TG) through a swimming protoco...
Does caffeine supplementation associated with paralympic powerlifting training ...
Menezes, Jainara Lima; Aidar, Felipe J.; Badicu, Georgian; Cataldi, Stefania; Carvutto, Roberto; Silva, Ana Filipa; Clemente, Filipe ManuelExercise, including resistance exercise with high loads, has positive hemodynamicresponses such as reduced systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), Pressure Product Rate (PPR), and estimated myocardial oxygen volume (MVO2). Caffeine (CA), used to improve performance, tends to interfere with BP and HR. This study aimed to analyze the effects of CAsupplementation on hemodyna...
A multivariate regression and discriminant canonical analysis of Isometric Mid-...
Aedo-Muñoz, Esteban; Reyes-Galvez , Natalia; López-Guzmán, Chris Mauro; Argothy-Bucheli, Rodrigo; Prat-Luri, Amaya; Bustamante-Garrido, AlejandroThis study measured the peak force (PF) in cadet inline speed skaters (ISS) and verified the physical measures that determine athletes' performance on the Isometric Mid-Thigh Pull Test (IMTP) through a multivariate regression and discriminant canonical analysis. A total of 36 high-performance male (n= 18; age= 17.4± 1.21 years; body mass= 65.1± 6.18 kg; height= 168.6± 5.1 cm) and female (n= 18; age= 17.4± 1.23 ...

Este estudo teve por objetivo desenvolver e validar um protocolo tempo-movimento especifico para o Boxe Inglês, utilizando o software Frami®. O presente protocolo foi desenvolvido sobre técnicas do boxe inglês, foram definidos grupos de ações e padrões de iníc...
Fundamental contributions of neuroscience to motor learning in children: a syst...
Torres-Moreno, María-José; Aedo-Muñoz, Esteban; Hernández-Wimmer, Cristian; Brito, Ciro José; Miarka, BiancaMotor learning generates synaptic neural connections that favour the motor environment and, also, various processes where our cognitive and executive functions intervene. Therefore, it is essential to know the different contributions that come from neuroscience linked to motor learning in a child. This study aimed to determine the fundamental contributions of neuroscience to motor learning in children. The meth...
Comparison of exercise and sports characteristics between binge-eating and heal...
de Souza, Letícia Nascimento; de Brito, Michele Andrade; Silva, Eliane Aparecida Ferraz; Müller, Vanessa Teixeira; Pérez, Diego Ignácio ValenzuelaThe present study compared exercise and sports characteristics between subjects with Binge Eating Disorder (BD) classification and a health group without binge eating. A randomized sample of 111 participants (23.1± 7.6 yrs.; 1.6± 0.6 m; 77.0± 16.9 kg) were classified and separated according BD classification (non-binging= 47; moderate binging n= 30; severe binging n= 40). For this, the BD Scale, Self-perceived ...
Lower experience increases concussion susceptibility in Brazilian jiu-jitsu pra...
dos Santos, Marco Antonio Ferreira; Oliveira, Lucas; Antoniêtto, Destter Álacks; da Silva, Francisco Nadilton Oliveira; Fernandes, André MarinhoThe present study is a descriptive-documental study that evaluates a survey database about Brazilian Jiu-Jitsu (BJJ) practitioners and concussions. We investigate any relationship between lifetime practice and the incidence of concussions in adults. For this, an online survey composed of 17 questions was sent to 42 BJJ coaches. The Survey Monkey platform was used to host the survey. Some demographic data was co...
Women Brazilian Jiu-jitsu practitioners showed a higher incidence of concussion...
de Carvalho, Gustavo Nascimento; Rego, Rafael da Silva; Chagas, Ana; Schreiner, Diana de Oliveira; Teixeira, Felipe GuimarãesKnowledge about the prevalence of concussion in combat sports is important information to keep athletes' and practitioners' physical integrity in different modalities such as Brazilian jiu-jitsu (BJJ). Therefore, this study aimed to compare concussions incidence in BJJ between men and women practitioners. A randomized sample of 779 (689 men and 90 women) BJJ practitioners (age: 32.4± 9.8 years, training-time: 5...
Acute effects of two HIIT protocols on oxidative responses
Carvalho, George Franklin Santana de; Marçal, Anderson Carlos; Aidar, Felipe José; Santos, Jymmys Lopes; Brito, Ciro José; Getirana-Mota, MárcioThe aim of this experimental study was to evaluate acute responses to oxidative stress (OS) after a single session of two HIIT protocols. 24 Wistar rats were divided into three groups (n= 8): sedentary control (SC), HIIT with a 7-minute volume (LW) and HIIT with 14-min (HW). After the protocol, blood was collected for the measurement of uric acid (UA), and the liver and the gastrocnemius muscle were collected f...
Suplementação aguda de arginina não influencia na hipotensão pós-exercício aeró...
Fernandes Silva, André Marques; Valenzuela Pérez, Diego Ignácio; dos Santos, Diego Alves; Deresz, Luis Fernando; Aedo Muñoz, Esteban ArielEste estudo avaliou os efeitos da suplementação aguda de arginina (ARG) sobre a hipotensão pós-exercício (HPE). Para tal 12 jovens fisicamente ativos participaram deste ensaio clínico randomizado, duplo-cego cruzado. Todos foram submetidos a duas condições experimentais (ARG ou placebo – PLA). 45 minutos após a suplementação realizou-se 30 min de exercício aeróbico de intensidade moderada (70-75% da frequência ...
