High‐fat diet and fructose drink introduced after weaning rats, induces a better human obesity model than very high‐fat diet

Thiago da Rosa Lima, Fabrício Azevedo Voltarelli, Lorena Silva Freire, Franciely Alves Silva, more

Journal of Food Biochemistry > 45 > 4 > n/a - n/a

In the present study, we associated a high‐fat diet (HF group: 45% kcal from lipids) or very high‐fat (VHF group: 60% kcal from lipids) diet with a fructose drink (10% fructose) for hydration. Normal rat chow that received the control diet (content 16.3% kcal from lipid–AIN93G) and water. The treatments were introduced soon after weaning and were administered for 70 days. We aimed to compare HF and...

Combination of resistance and aerobic exercise for six months improves bone mass and physical function in HIV infected individuals: A randomized controlled trial

Morteza Ghayomzadeh, Conrad P. Earnest, Daniel Hackett, SeyedAhmad SeyedAlinaghi, more

Scandinavian Journal of Medicine & Science in Sports > 31 > 3 > 720 - 732

To evaluate the effect of combined resistance and aerobic training (RT+AT) on regional bone mineral density (BMD) and physical performance in people living with HIV (PLWH). Forty PLWH (20 men and 20 women) were randomized into RT+AT group (n = 20; age = 38.3 ± 4.9) or non‐exercise control group (n = 20; age = 37.9 ± 5.1). The RT+AT group was required to perform a nonlinear periodized resistance training...

Effects of high-protein diet containing isolated whey protein in rats submitted to resistance training of aquatic jumps

Eudes Thiago Pereira Avila, Thiago da Rosa Lima, Ramires Alsamir Tibana, Paula Caroline de Almeida, more

Nutrition > 2018 > 53 > C > 85-94

Isolated whey protein (IWP) can decrease body fat compared with other protein sources. The present study verified the effects of high protein diet (HD) containing IWP on several parameters of rats subjected to resistance training (RT).Thirty-two male Wistar rats (60 days of age) were separated into four groups (n = 8/group): sedentary normoproteic (IWP 14%; SN); sedentary hyperproteic (IWP 35%; SH);...

Metabolic and cardiorespiratory acute responses to fasting versus feeding during high-intensity interval training

Cristiane Rocha Silva, Paulo Vitor Santana, Pauliana Conceição Mendes, Bruno Saraiva, more

Sport Sciences for Health > 2018 > 14 > 2 > 347-355

Purpose The aim of this study was to investigate the effects of sprint interval training (SIT) and feeding state [fasted (FAST) or fed (FED)] on metabolic and cardiorespiratory parameters. Methods Twelve active men (age 23 ± 3 years; body mass 76.43 ± 4.06 kg; height 175.6 ± 4.98 cm; body mass index 24.78 ± 0.56 kg/m²; VO_2peak 52.33 ± 4.87 mL/min/kg) volunteered to participate in this study. Participants...

Endurance exercise training decreased serum levels of surfactant protein D and improved aerobic fitness of obese women with type-2 diabetes

Sajjad Rezaei, Mahdieh Molanouri Shamsi, Mehdi Mahdavi, Azadeh Jamali, more

Diabetology & Metabolic Syndrome > 2017 > 9 > 1 > 1-8

Background Surfactant protein D (SP-D) is a member of the collectin family and is an important component of the pulmonary innate host defense. To find the relationship between exercise training and SP-D in diabetes, we examined the possible effects of a 10-week endurance exercise-training program on serum levels of SP-D, leptin, lipid profile and insulin resistance in obese women with type-2 diabetes...

Effect of administration of high-protein diet in rats submitted to resistance training

Thiago Rosa Lima, Eudes Thiago Pereira Ávila, Géssica Alves Fraga, Mariana Souza Sena, more

European Journal of Nutrition > 2018 > 57 > 3 > 1083-1096

Purpose Although there is limited evidence regarding the pathophysiological effects of a high-protein diet (HD), it is believed that this type of diet could overload the body and cause damage to the organs directly involved with protein metabolism and excretion. The aim of this study was to verify the effects of HD on biochemical and morphological parameters of rats that completed a resistance training...

Acute eccentric resistance exercise decreases matrix metalloproteinase activity in obese elderly women

Dahan da Cunha Nascimento, James Wilfred Navalta, João Luiz Quagliotti Durigan, Rita de Cassia Marqueti, more

Clinical Physiology and Functional Imaging > 36 > 2 > 139 - 145

The association of ageing with obesity commits elderly women and has been correlated with multiple degenerative processes, which could be occasioned by an enhancing in levels of matrix metalloproteinase‐2 and metalloproteinase‐9 (MMPs) as well by an cytokine unbalance that included an enhancing on interleukin‐6 (IL‐6). Furthermore, other factors could be also related to degenerative process, as they...

Elevated glycated hemoglobin levels impair blood pressure in children and adolescents with type 1 diabetes mellitus

Sandra Oliveira, Dahan Cunha Nascimento, Ramires Alsamir Tibana, Samuel Lima Oliveira, more

Diabetology & Metabolic Syndrome > 2016 > 8 > 1 > 1-6

Background Deregulation of glycemic and glycated hemoglobin (HbA₁) levels accelerate the progression of cardiovascular complications in type 1 diabetes mellitus (T1DM). The aim of this study was to investigate the association between HbA₁ and changes in blood pressure of children and adolescents with T1DM. Methods A total of 60 children and adolescents were recruited and allocated into two groups...

Understanding the individual responsiveness to resistance training periodization

Jonato Prestes, Dahan Cunha Nascimento, Ramires Alsamir Tibana, Tatiane Gomes Teixeira, more

AGE > 2015 > 37 > 3 > 1-13

This study was designed to compare the effects of linear periodization (LP) and undulating periodization (UP) on functional capacity, neuromuscular function, body composition, and cytokines in elderly sedentary women. We also aimed to identify the presence of high responders (HR), medium responders (MR), and low responders (LR) for irisin, interleukin-1 beta (IL-1β), toll-like receptor-4 (TLR-4),...

The Response of Matrix Metalloproteinase-9 and -2 to Exercise

Dahan Cunha Nascimento, Rita Cassia Marqueti Durigan, Ramires Alsamir Tibana, João Luiz Quagliotti Durigan, more

Sports Medicine > 2015 > 45 > 2 > 269-278

Background Matrix metalloproteinases (MMPs) are a major group of enzymes that play essential roles in normal functioning of diverse tissues during growth, development, and aging. However, among the MMPs little is known regarding the role of exercise in MMP-9 and MMP-2 function in humans. Objective The aim of this study was to provide a systematic comprehensive review of the literature examining...
