Adulthood starts after youth and is characterized by the completion of growth and the achievement of organic and psychological maturity. Obesity and other preventable diseases related to lifestyle are common at this age. A complete, balanced and sufficient diet, together with exercise are important in order to prevent and treat these diseases. Several studies have brought about the mechanisms by which the incorporation of milk and dairy products to diet is beneficial in order to prevent and treat these diseases...

Hydration is arguably among the foremost priorities youth athletes, parents, and coaches habitually consider as vital for sports. Insufficient hydration and a resultant measurable sweat-induced body water deficit can negatively affect performance and, in some athletic scenarios, can be a danger to a young athlete's health and safety, especially during vigorous physical activity in a warm-to-hot environment. Accordingly, it is essential to be well hydrated prior to practice, training, and competition and minimize total body water deficits incurred while being mindful of the greater sweat losses and hydration needs/challenges that accompany physical growth and maturation...

BACKGROUND: Weight cutting is a common practice in amateur boxing with the purpose of taking advantage of rivals competing in weight divisions below the athlete's normal weight. Dehydration is a common weight-manipulating technique in boxing, and is known as a serious health-threatening behavior. In this study, we investigated field hydration status differences between the weight class categories in elite junior boxers. METHODS: The sample of subjects included 21 male junior boxers from Croatia, Germany and Hungary (all national team members)...

Hydration is important post-renal transplant to maintain adequate renal perfusion and graft function. Adherence to fluid recommendations is challenging given barriers to staying hydrated. There are no studies of adherence to fluid intake recommendations following pediatric renal transplant. Through this pilot study, we sought to determine whether the use of a commercially available interactive water bottle would lead to better adherence to recommended fluid intake and improved kidney functioning post-transplant relative to standard of care...

Hyaluronan (hyaluronic acid, HA) is a ubiquitous linear polysaccharide endowed with some exceptional physicochemical properties such as strong hydration and viscoelasticity that depend on the size of the molecule. It plays a variety of important physiological roles in tissue hydration and mechanical protection, for example in the umbilical cord, skin and most other tissues. Since its large scale preparation and the invention by E.A. Balazs of the preparation of its non-inflammatory fraction (NIF-NaHA), there have been several important medical and cosmetic applications, most notably of viscosurgery for eye operation, intra-articular injections for osteoarthritis and also for wrinkle filling on the face, as well as for drug administration...

Although there are many studies demonstrating a high percentage of adult athletes who start exercise in suboptimal hydration state, limited data concerning hydration levels in athletic youth exist. The purpose of this study was to identify the hydration status of elite young athletes of different sports, during a typical day of training. Fifty-nine young elite male athletes from different sports (basketball, gymnastics, swimming, running, and canoeing) participated in the study (age: 15.2 ± 1.3 years; years of training: 7...

Diabetes mellitus is the most common group of metabolic diseases and is characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Most patients with diabetes are type 2 (90%); the remaining patients have type 1 disease. Athletes with diabetes range from the athlete participating in various youth sports to the competitive Olympic athlete and present a significant challenge to themselves and the medical staff who care for them on a daily basis. Each sport and the type of exercise have their own effects on diabetes management with numerous factors that significantly affect glucose levels, including stress, level of hydration, the rate of glycogenolysis and gluconeogenesis, and the secretion of counter-regulatory hormones...

This study was a pilot project, set up to assess ageing skin using a multi-disciplinary approach. The main aim of this study was to evaluate whether the use of more radical ('medical') treatments in the management of skin ageing would bring superior results and ultimately make people look younger, than the use of cosmetics ('non-medical' treatments). A simple post-hoc study design was used, whereby medical treatments varied within the group, all of them completed at least 2 weeks before the start of the study...

The purpose of the study was to determine the hydration status, fluid intake, and electrolyte losses of 21 male professional youth soccer players (age 17.1 ± 0.7 y) training in a cool environment. Pretraining and posttraining measurements of body mass, urine (freezing-point osmolality method), and sweat concentration (flame-emission spectroscopy) were collected. Fourteen players were found to be hypohydrated before training. The amount of fluid lost due to exercise equated to a 1.7% loss in body mass, which equated to a gross dehydration loss of 0...

As the number of youth sports participants continues to rise over the past decade, so too have sports related injuries and emergency department visits. With low levels of oversight and regulation observed in youth sports, the responsibility for safety education of coaches, parents, law makers, organizations and institutions falls largely on the sports medicine practitioner. The highly publicized catastrophic events of concussion, sudden cardiac death, and heat related illness have moved these topics to the forefront of sports medicine discussions...

Results of new research indicate that, contrary to previous thinking, youth do not have less effective thermoregulatory ability, insufficient cardiovascular capacity, or lower physical exertion tolerance compared with adults during exercise in the heat when adequate hydration is maintained. Accordingly, besides poor hydration status, the primary determinants of reduced performance and exertional heat-illness risk in youth during sports and other physical activities in a hot environment include undue physical exertion, insufficient recovery between repeated exercise bouts or closely scheduled same-day training sessions or rounds of sports competition, and inappropriately wearing clothing, uniforms, and protective equipment that play a role in excessive heat retention...

There are a variety of biological mechanisms that contribute to specific characteristics of ageing skin; for example, the loss of skin structure proteins, increased susceptibility to UV-induced pigmentation and/or loss of hydration. Each of these biological processes is influenced by specific groups of genes. In this research, we have identified groups of genes associated with specific clinical signs of skin ageing and refer to these as functional 'youth gene clusters'. In this study, quantitative real-time polymerase chain reaction (qPCR) was used to investigate the effects of topical application of salicin in regulating the expression of functional 'youth gene clusters' to reflect a more youthful skin profile and reduce the appearance of attributes associated with skin ageing...

We aimed to evaluate whether an intervention program emphasizing in increased fluid intake can improve exercise performance in children exercising in the heat. Ninety-two young athletes participated in the study (age: 13.8 ± 0.4 years, weight: 54.9 ± 1.5 kg). Thirty-one (boys: 13, girls: 18) children served as the control group (CON) and 61 (boys: 30, girls: 31) as the intervention (INT). Volunteers had free access to fluids. Hydration was assessed on the basis of first morning urine. A series of field tests were used to evaluate exercise performance...
