Although the nutrient requirements and dietary intake of athletes have been thoroughly investigated, little is known about the influences on their food choice, particularly prior to and during competition. This study sought to investigate factors that influence food selection of athletes at two similar international competition events: the Melbourne 2006 and Delhi 2010 Commonwealth Games. A secondary aim was to explore differences in these factors between at each event given the culturally diverse locations...

Youth sports participation numbers continue to grow in the United States. A shift toward sport specialization has caused an increase in sport training frequency and intensity that places the growing athlete at risk for overtraining, nutritional deficits, and injuries. Individuals who participate in endurance sports are at especially high risk. Youth runners and swimmers are high-risk populations that require special attention to their training schedules, nutritional intake, and injuries. Appropriate scheduling of training, dedicating time to rest, and nutrition education can help prevent problems in the endurance athlete...

BACKGROUND: Women with pathogenic BRCA germline mutations have an increased risk for breast and ovarian cancer that seems to be modified by life-style factors. Though, randomized trials investigating the impact of lifestyle interventions on cancer prevention and prognosis in BRCA carriers are still missing. METHODS: We implemented a multicenter, prospective randomized controlled trial in BRCA1/2 patients, comparing a lifestyle intervention group (IG) with a control group (CG) with the primary aim to prove feasibility...

Recent interest has focused on maintenance of healthy levels of redox signalling and the related oxidants; these parameters are crucial for providing us with concrete nutritional targets that may help us to better understand and maintain "optimal health". Following the above hypothesis, we performed a pilot double-blind, crossover, placebo-controlled, single dose study to measure the dose-dependent effects of a proprietary plant-based dietary supplement labelled here as S7 (SPECTRA7), related to how it affected the cellular metabolic index (CMI) in healthy human participants (n = 8)...

BACKGROUND: Athletes may complete consecutive exercise sessions with limited recovery time between bouts (e.g. ≤ 4 h). Nutritional strategies that optimise post-exercise recovery in these situations are therefore important. OBJECTIVE: This two-part review investigated the effect of consuming carbohydrate (CHO) and protein with water (W) following exercise on subsequent athletic (endurance/anaerobic exercise) performance. DATA SOURCES: Studies were identified by searching the online databases SPORTDiscus, PubMed, Web of Science and Scopus...

Cardiovascular fitness has decreased and obesity has increased in youth-adults world-wide during the last ten years. Therefore, there is an urgent need to find out optimal exercise training programs for improving physical performance and health outcomes, especially, among sedentary women. Subjects were 25-30-year-old females with very low physical activity, and 65 % of them were overweight (BMI >25). They performed endurance and strength training three times a week for nine weeks. Independent strength training and instructed endurance training by indoor cycling were prescribed...

Sarcopenia and physical deconditioning are frequent complications in patients with cirrhosis and end-stage liver disease (ESLD). They are the end result of impaired dietary intake, chronic inflammation, altered macro- and micronutrient metabolism, and low physical activity. Frailty is the end result of prolonged sarcopenia and physical deconditioning. It severely affects a patient's functional status, and presents in about 1 in 5 patients on the liver transplant (LT) waitlist. Sarcopenia, poor physical fitness/cardiopulmonary endurance, and frailty are all associated with increased mortality in ESLD...

The goal of clinicians managing nutrition support for patients with home parenteral nutrition (HPN) is to adapt nutrition needs to best serve the consumers, so they may have the best quality of life despite specialized nutrition needs. Some HPN consumers may desire to participate in endurance athletics, which will require special considerations. This review is intended to outline key nutrition differences in endurance athletes that a nutrition support team should consider when providing HPN.

Both athletes and coaches should have adequate nutrition knowledge to understand the importance of diet on athletic performance, recovery, and health. Nutrition knowledge can be assessed reliably only by validated knowledge questionnaires. The aim of this study was to develop a reliable and valid questionnaire for assessing the nutrition knowledge of young endurance athletes and their coaches. The questionnaire was developed with an expert panel and pilot tested by athletes, coaches, and students. Content, face, and construct validities both as test-retest reliability and internal consistency reliability were ensured when the current questionnaire was developed...

This review examines the role of nutritional strategies to improve lifetime performance in ruminants. Strategies to increase ruminants' productive longevity by means of nutritional interventions provide the opportunity not only to increase their lifetime performances and their welfare, but also to decrease their environmental impact. This paper will also address how such nutritional interventions can increase herd efficiency and farm profitability. The key competencies reviewed in this article are redox balance, skeletal development and health, nutrient utilization and sustainability, which includes rearing ruminants without antibiotics and methane mitigation...

The early preimplantation embryo has been rigorously studied for decades to understand inherent reproductive and developmental mechanisms driving its morphogenesis from before fertilisation through to and beyond implantation. Recent research has demonstrated that this short developmental window is also critical for the embryo's interaction with external, maternal factors, particularly nutritional status. Here, maternal dietary quality has been shown to alter the pattern of development in an enduring way that can influence health throughout the lifetime...

Bone stress injuries occur when forces applied to a bone for an extended period exceed the ability of the bone to adequately remodel. These injuries, which range from stress reactions to nondisplaced and even displaced fractures, most often affect people who experience high levels of repetitive stress and loading in the lower extremity or changes in physical activity level. For example, stress fractures are common in endurance athletes, in athletes engaged in preseason and early-season conditioning, and in military recruits...

Early life stress has enduring effects on behavior and physiology. However, the effects on hormones and stress physiology remain poorly understood. In the present study, parents of zebra finches of both sexes were exposed to an increased foraging paradigm from 3 to 33days post hatching. Plasma and brains were collected from chicks at 3 developmental time points: post hatching days 25, 60 and adulthood. Plasma was assayed for testosterone (T), estradiol (E2), and corticosterone (CORT). The paraventricular nucleus of the hypothalamus was assessed for corticotrophin releasing factor (CRH) and glucocorticoid receptor (GR) expression...

Biomarker discovery and validation is a critical aim of the medical and scientific community. Research into exercise and diet-related biomarkers aims to improve health, performance, and recovery in military personnel, athletes, and lay persons. Exercise physiology research has identified individual biomarkers for assessing health, performance, and recovery during exercise training. However, there are few recommendations for biomarker panels for tracking changes in individuals participating in physical activity and exercise training programs...

REVIEW
Ronak A Gor, Sean P Elliott
Surgery for patients with neurogenic urinary tract dysfunction (nLUTD) is indicated when medical therapy fails, to correct conditions affecting patient safety, or when surgery can enhance the quality of life better than nonoperative management. Examples include failure of maximal medical therapy, inability to perform or aversion to clean intermittent catheterization, refractory incontinence, and complications from chronic, indwelling catheters. Adults with nLUTD have competing risk factors, including previous operations, obesity, poor nutritional status, complex living arrangements, impaired dexterity/paralysis, and impaired executive and cognitive function...
