Aerobic Exercise Increases the Damage to the Femoral Properties of Growing Rats...
Miranda,Denise Coutinho de; Lavorato,Victor Neiva; Carneiro-Júnior,Miguel Araújo; Paula,Ana Beatriz Rezende de; Silva,Karina Ana; Drummond,Filipe RiosAbstract The present study investigated the effects of aerobic physical training on the femoral morphological, densitometric and biomechanical properties in growing male rats subjected to protein-based malnutrition. Four-week-old male Wistar rats were randomized into groups of 10 animals: Control Sedentary (CS), Control Trained (CT), Malnourished Sedentary (MS) and Malnourished Trained (MT). Control and malnour...
Thermoregulation in Hypertensive Rats during Exercise: Effects of Physical Trai...
Gomes,Luis Henrique Lobo Silame; Drummond,Lucas Rios; Campos,Helton Oliveira; Rezende,Leonardo Mateus Teixeira de; Carneiro-Júnior,Miguel AraújoAbstract Background: Spontaneously hypertensive rats (SHR) show deficit in thermal balance during physical exercise. Objective: To assess the effects of low-intensity physical exercise training on thermal balance of hypertensive rats undergoing an acute exercise protocol. Methods: Sixteen-week-old male Wistar rats and SHR were allocated into four groups: control Wistar rats (C-WIS), trained Wistar (T-WIS), cont...
Estresse térmico ambiental e termorregulação em jogadores de futebol: uma revis...
Rezende,Leonardo Mateus Teixeira de; Carneiro-Júnior,Miguel Araújo; Natali,Antônio José; Prímola-Gomes,Thales NicolauResumo O objetivo do estudo foi fazer uma revisão sistemática acerca dos efeitos do estresse térmico ambiental sobre a termorregulação em jogadores de futebol. Foram avaliados estudos em bases de dados pertencentes ao portal Periódicos Capes. Foi empregado o método Prisma para o desenvolvimento da revisão. Jogadores de futebol apresentam grande aumento da temperatura corporal associada à redução de desempenho f...
Moderate Continuous Aerobic Exercise Training Improves Cardiomyocyte Contractil...
Rodrigues,Aurora Corrêa; Natali,Antônio José; Cunha,Daise Nunes Queiroz da; Costa,Alexandre Jayme Lopes Dantas; Moura,Anselmo Gomes deAbstract Background: The lack of cardiac β1-adrenergic receptors (β1-AR) negatively affects the regulation of both cardiac inotropy and lusitropy, leading, in the long term, to heart failure (HF). Moderate-intensity aerobic exercise (MCAE) is recommended as an adjunctive therapy for patients with HF. Objective: We tested the effects of MCAE on the contractile properties of left ventricular (LV) myocytes from β1...
Match internal load in youth elite soccer players is period, playing position a...
Silva,Cristiano D. da; Natali,Antônio José; Carling,Christopher; Lima,Jorge R. Perrout de; Bara Filho,Mauricio G.; Garcia,Emerson S.Abstract Aims: The aims of this study were: i) to verify whether player internal load (PIL) monitored via heart rate (HR) varies with game-time and playing position; ii) whether intermittent running capacity (IRC) is related to the maintenance of within-match PIL in elite youth (U-15) soccer players. Method: Twenty-one elite soccer players (14±0.5 yrs, 172±7 cm, 63±6 kg) had their heart rate monitored (beats/mi...
ÓXIDO NÍTRICO E DINÂMICA DE CA2+ EM CARDIOMIÓCITOS: INFLUÊNCIA DA CAPACIDADE DE...
Drummond,Lucas Rios; Araujo Carneiro-Júnior,Miguel; Lauton-Santos,Sandra; Capettini,Luciano dos Santos Aggum; Mesquita,Thássio Ricardo RibeiroRESUMO Introdução: A capacidade intrínseca para o exercício aeróbico está relacionada com o inotropismo cardíaco. Por outro lado, a participação do óxido nítrico (NO) como mensageiro intracelular sobre a dinâmica do Ca2+ ainda permanece desconhecida em ratos com diferentes capacidades intrínsecas para o exercício. Objetivo: Avaliar se o NO modula diferentemente o transiente intracelular de Ca2+ e liberações esp...
CONSUMO DE ÁLCOOL E A INFLUÊNCIA DO EXERCÍCIO FÍSICO NA ATIVIDADE ENZIMÁTICA DE...
Righi,Thamires; Carvalho,Camilo Amaro de; Ribeiro,Lucas Mota; Cunha,Daise Nunes Queiroz da; Paiva,Ana Carolina Silva; Natali,Antônio JoséRESUMO Introdução: Biomarcadores vem sendo utilizados para monitorar o uso do álcool e, atualmente, os mais sensíveis e específicos são enzimas hepáticas, por exemplo, gama glutamiltransferase (GGT), alanina aminotransferase (ALT), aspartato aminotransferase (AST) e fosfatase alcalina (ALP). Objetivo: Verificar, a partir da experimentação animal, as alterações provocadas pelo uso de álcool e pela prática de ati...
Association of inflammation, dyslipidemia, obesity and physical activity status...
Guedes,Juliano Magalhães; Mamêde Neto,José Bontempo; Andaki,Alynne Christian Ribeiro; Pereira,Patrícia Feliciano; Oliveira,Michelle Dias deAbstract The aim of this study was to verify the association between inflammatory biomarkers, dyslipidemia, obesity and physical activity status in 10-years old children. Ninety-four children participated in this study and were classified into eutrophic (n=36), overweight (n=34) or obese (n=24) according to their body mass index (BMI). The genic expression of interleukin 6 (IL-6), tumor necrosis factor alpha (T...
Achilles tendon of wistar rats treated with laser therapy and eccentric exercise
Souza,Maria Verônica de; Silva,Carlos Henrique Osório; Silva,Micheline Ozana da; Costa,Marcela Bueno Martins da; Dornas,Raul FelipeABSTRACT Introduction: Both laser therapy and eccentric exercises are used in tendon injuries. However, the association of these physiotherapeutic modalities is yet little investigated. Objective: To evaluate the effect of low-level laser therapy associated to eccentric exercise (downhill walking) on Achilles tendinopathy of Wistar rats. Method: Eighteen Achilles tendon from 15 adult male Wistar rats were used....
Histomorphometric analysis of the Achilles tendon of Wistar rats treated with l...
Souza,Maria V. de; Moreira,José do C.L.; Silva,Micheline O. da; Crepaldi,Júlio; Silva,Carlos Henrique Osório; Garcia,Silvana L.R.; Natali,Antônio JoséAbstract: Low-level laser therapy is recommended for the treatment of tendinopathies despite the contradictory results related to the ideal dose of energy, wavelength and time of application. This study aimed to assess the effects of laser therapy and eccentric exercise on tendinopathy of the Achilles tendon of Wistar rats. Forty-eight adult male rats were randomly distributed into four groups (L= laser; E= ecc...
