“Creatine supplementation can improve impact control in high-intensity interval training”
High-intensity interval training (HIIT) has recently become a widespread exercise approach, since it seems to be a time-efficient way to induce similar or even improved adaptations of conventional endurance training (1 –5). HIIT consists of repeated bouts of high-intensity intervals of exercise interspersed with low-intensity or passive rest periods. HIIT is an exercise mode designed to repeatedly stress the body with intense stimulus in different types of exercise, including running. As a result, previous studi es have shown that HIIT can also lead to high levels of mechanical load (6–9). (Source: Nutrition)

Performance and altitude: is there anything that nutrition can do for it?
High-altitude regions are associated with sports, especially football, and climbing. However, tourists, workers such as miners and plane pilots, and residents of these regions also suffer from the same rigors [1]. In South America, for example, each year approximately 4,000 people visit the Aconcagua Provincial Park, in the Argentine Andes, where the maximum altitude can reach 6,960m. Curiously, only 60% of these people visit the park because of the climbing options it offers. The other 40% are attracted to the park by the natural beauty, in spite of the risks inherent to the pass in these regions. (Source: Nutrition)

Vitamin D, muscle recovery, sarcopenia, cachexia and muscle atrophy
The words muscle atrophy, muscle hypertrophy, sarcopenia and cachexia were crossed over with Vitamin D in a Pubmed search. All original contributions, along with reviews on the topic were included, and no publications, in the last 10 years, discarded. The papers retrieved different topics such as Vitamin D in skeletal muscle; Vitamin D in circulation; Vitamin D, Sarcopenia and Muscle Atrophy; Vitamin D and Cachexia and Vitamin D and Muscle Recovery.

A New Clinical Perspective: Treating Obesity with Nutritional Coaching v. Energy-restricted Diets
Obesity is an abnormal or excessive fat accumulation potentially leading to development of diabetes, cardiovascular diseases, musculoskeletal disorders, obstructive sleep apnea, and cancers that now affects more than 1.8 billion people [1]. Lifestyle interventions are often recommended to treat obesity with energy-restricted diets (ERD) most commonly used for management of this disease. The U.S. weight loss market is valued at over $66 billion and it seems thousands of new diets are created every year [2]. (Source: Nutrition)

Fat-free mass in adolescent athletes: accuracy of bioimpedance equations and identification of new predictive equations
A correct assessment of body composition in adolescent athletes is fundamental. It allows the prescription of adequate training and diet, and reduces the risk of mistakes that could affect health and athletic performance (1). Furthermore, it makes it possible to monitor the effects of physical activity and sports practice, and to evaluate physical performance. In fact, fat-free mass (FFM) is considered a predictor of muscular strength (2) and physical fitness (3), while vigorous exercise has shown to be associated with muscular strength (4) and lean mass (5) (Source: Nutrition)

Effects of glutamine and alanine supplementation on muscle fatigue parameters of rats submitted to resistance training
Muscle fatigue designates biochemical changes occurring within the skeletal muscle cell, which reduce strength and power, impairing physical performance [1,2]. One of the main causes of this phenomenon is the reduction of energy substrates for the continuity of the exercise, evidenced by increased concentrations of enzymes and metabolites from the adenosine triphosphate (ATP) metabolism, such as adenosine monophosphate deaminase (AMPD), xanthine, and hypoxanthine, and by the decrease of energy stores, such as glycogen.

Carbohydrate Restriction: Friend or Foe of Resistance-Based Exercise Performance?
Glucose availability is important for muscular performance lasting greater than 30 seconds, and dietary carbohydrates are now considered the most important of the three macronutrients to fuel endurance sports [1]. However, prior to the late 19th century, athletes, coaches, and even some scientists believed protein was the major source of energy for muscular activity [2]. From a historical perspective, Zuntz [3, 4], Frentzel and Reach [5], and Krogh and Lindhard [6] demonstrated through a series of landmark experiments that carbohydrates and lipids fuel exercise, with the varying proportions of the two macronutrients in the...

Why Do Current Strategies for Optimal Nutritional Therapy Neglect the Microbiome?
Strategies for providing optimal nutritional therapy have evolved over time, with the emphasis on specific directives (such as route, use of immunonutrition, high protein, organ-specific formulas, etc.) achieving variable degrees of success for improving outcomes in the Intensive Care Unit (ICU). As the largest immune organ in the body comprising the largest interface between the host and the external environment, the gut can have an amplifying effect on a pattern of dysbiosis, immune dysregulation, and multiple organ failure seen in the critically ill patient.

The effects of regular high-cocoa chocolate intake on arterial stiffness and metabolic characteristics during exercise
Fruits, wines, and chocolate are polyphenol-rich, and their beneficial effects are thus attracting increasing attention [1-4]. Recent meta-analyses have shown that high-cocoa chocolate or cocoa products favorably affect cardiometabolic health [1-3]. Most individuals can easily intake chocolate, and thus high-cocoa chocolate could be an effective cardiovascular preventive strategy for large populations [5]. Therefore, further scientific evidence of the benefits of high-cocoa chocolate is needed. (Source: Nutrition)

Today's food landscape: not a pretty picture
Food has emerged globally in the last decade as a very hot topic for the media, government, opinion leaders and the public. This is driven in large part both by heightened interest in health and wellness and by concerns about obesity and chronic disease. A convergence of issues around food and food systems lead to a complex and challenging environment. (Source: Nutrition)

Ethical issues in health communication: health-related news sourcingpractices
The field of health science communication (HSC) has multiple stakeholders including researchers, scientific societies and organizations, government agencies, universities, news and media organizations and public information officers [1,2]. The optimization of HSC between researchers and the public is crucial in terms of its impact on governmental decision-making, health policies, health promotion, disease prevention and self-care [1,3]. Health communication should adhere to the principles of beneficence, non-maleficence, respect for personal autonomy, and justice [4]. (Source: Nutrition)

Drivers of food choice: a cognitive structure approach to the determinants of food choice and implications for affecting behavior change
Three factors are considered of critical importance in changing consumer behaviors towards healthier choices: providing healthier alternatives to the consumer by introducing healthier reformulations of existing products, providing people with more knowledge on the intricate relationship between food and health and the motivation of the consumer to make healthier choices. Ultimately, for a behavioral change to occur, all three factors need to be present. People can be very well informed about the consequences of their choices, but if they are not motivated to make healthy choices, this information will have no effect. (Source: Nutrition)

Food habits and cancer prevention
Physical activity, healthy nutrition and lack of stress are the three most important components of health. Inadequate levels of physical activity, obesity, unhealthy diet and chronic stress (e.g. tobacco, excessive alcohol and other harmful physical, chemical, biological, psychological and social stress) can induce an unhealthy and unhappy life that leads to chronic diseases such as hypertension, diabetes and cardiovascular disease, cancer and Alzheimer's and to premature death. The mechanisms are generally thought to involve increased oxidative stress, inflammation, epigenetic changes and metabolic changes. (Source: Nutrition)
