The purpose of this study was to examine the effects of sodium citrate (CIT) ingestion on 30 km cycling performance. Eight trained male cyclists (VO2max = 54.7 +/- 1.7 ml.kg-1.min-1) performed two 30 km cycling time trials. The trials were double blind and randomly assigned from CIT or placebo (PLC), with both dosages at 0.5 g.kg body wt-1. Blood samples(More)
The question of whether iron deficiency has direct adverse effects on vertebral trabecular bone and long bones was answered by this study. Four groups of female weanling rats were fed for 5 wk diets that were 1) control; 2) calcium restricted, 1.0 g Ca/kg diet; 3) iron deficient, <8 mg Fe/kg diet; or 4) control, pair-fed to the iron-deficient group.

A methodology combining finger-pricked blood sampling, microwave accelerated fatty acid assay, fast gas chromatography data acquisition, and automated data processing was developed, evaluated and applied to a population study. Finger-pricked blood was collected on filter paper previously impregnated with 0.05 mg of the antioxidant butylated hydroxytoluene(More)
The involvement of the gut microbiota in metabolic disorders, and the ability of whole grains to affect both host metabolism and gut microbial ecology, suggest that some benefits of whole grains are mediated through their effects on the gut microbiome. Nutritional studies that assess the effect of whole grains on both the gut microbiome and human physiology(More)
Dietary fiber and whole grains contain a unique blend of bioactive components including resistant starches, vitamins, minerals, phytochemicals and antioxidants. As a result, research regarding their potential health benefits has received considerable attention in the last several decades. Epidemiological and clinical studies demonstrate that intake of(More)
BACKGROUND For elderly women, insufficient data exist to assess the accuracy of the assumed mean protein requirement of 0.6 g of protein x kg(-1) x day(-1), and the adequacy of the current Recommended Dietary Allowance (RDA) of 0.8 g of protein x kg(-1) x day(-1). The aims of this study were to assess the mean protein requirement and suggested safe and(More)
BACKGROUND L-glutamine (GLN) may have an ergogenic effect during exercise considering its base generating potential. We attempted to determine whether GLN ingestion influences acid-base balance and improves high intensity exercise performance. METHOD Ten trained males performed five exercise bouts on a cycle ergometer at 100% of VO2 peak. The first four(More)
BACKGROUND Aging is associated with reductions in muscle mass and strength, but nutrition and exercise interventions can delay this progression and enhance the quality of life. OBJECTIVE We examined whether the predominant source of protein consumed by older men influenced measures of muscle size and strength, body composition, resting energy expenditure,(More)
OBJECTIVE To test the hypothesis that older men who consumed a vegetarian (lacto-ovo) diet would develop a lower iron status compared with older men who consumed a beef-containing diet during a period of resistive training (RT). DESIGN Experimental, repeated measures study. SUBJECTS Twenty-one healthy men aged 59 to 78 years, with a BMI range of 24 to(More)
The purpose of this investigation was to clarify, via a meta-analysis, whether the literature favors a high-fat or a high-carbohydrate diet to yield superior endurance exercise performance. Twenty published trials were analyzed to compare exercise performance under different diets. The average effect size of -0.60 indicated that subjects following a(More)
