OBJECTIVE
We evaluated the effects of carbohydrate (CHO) supplementation on markers of bone turnover in elite runners.
METHODS
Twenty-four male runners were randomly assigned to two groups--a CHO and a control (CON) group--using a double-blind design. The participants were submitted to an overload

Low-carbohydrate, high-fat (LC-HF) diets are popular for inducing weight loss in adults and are also used as part of a treatment for children with epilepsy. However, potential risks and side effects remain controversial. We investigated effects of LC-HF diets on growth, bone mineral density (BMD),

To make a broad survey of the effect of components of the human diet on bone resorption, a few items from the following categories were added to rat diets: vegetables, fruits, beans, nuts and seeds, mushrooms, carbohydrate sources and beverages. The effect on bone resorption was measured by the

A glycoprotein which stimulates bone resorption in vitro has been purified at least 375-fold from human cancer ascites fluid. Purification was accomplished utilizing fractionation with ammonium sulfate, anion exchange chromatography, high-performance size exclusion chromatography, adsorptive

It has been suggested that bone health in adulthood is programmed by development in utero. Most previous investigations addressing this topic have focussed on bone mineral density or content, rather than other indicators of bone health, such as biochemical markers of bone turnover. This study

OBJECTIVE
The effect on bone, protein, carbohydrate and lipid homeostasis as well as body composition of the administration of growth hormone to adult patients with growth hormone deficiency was studied.
METHODS
Growth hormone was administered at a dose of 25 micrograms/kg/day with a maximum of 1.48

This study aimed to investigate the effect of feeding carbohydrate and protein (CHO + PRO), immediately or 2 h after an exhaustive run, on the bone turnover response in endurance runners.
Ten men (age = 28 ± 5 yr, height = 1.74 ± 0.05 m, body mass [BM] = 69.7 ± 6.3 kg) performed treadmill running at

A randomised, parallel-design dietary intervention study was conducted in women (aged 45-75 years) with prehypertension or stage 1 hypertension. The aim was to compare the effects on bone turnover of a low-Na base-producing (LNAB) Dietary Approaches to Stop Hypertension (DASH)-type diet (including

Bone resorption is increased after running, with no change in bone formation. Feeding during exercise might attenuate this increase, preventing associated problems for bone. This study investigated the immediate and short-term bone metabolic responses to carbohydrate (CHO) feeding during treadmill

KEY POINTS
Reduced carbohydrate (CHO) availability before and after exercise may augment endurance training-induced adaptations of human skeletal muscle, as mediated via modulation of cell signalling pathways. However, it is not known whether such responses are mediated by CHO

Rats, submitted to a sucrose diet for 12 months, were normally fed for another 6 months either with or without addition of the unsaponifiable residue of vegetable oils. It appears that unsaponifiable substances reinforce the collagen fiber network of the periodontium. The presence of a dense

Phosphate is an abundant mineral found in the body. The body store of phosphate is 500 to 800 g, with 85% of the total body phosphate present in crystals of hydroxyapatite in the bone — about 10% found in muscles and bones in association with proteins, carbohydrates, and lipids. The rest gets

Glucagon-like peptide-2 (GLP-2) is a 33-amino acid peptide derived from proteolytic cleavage of proglucagon by prohormone convertase 1/3 in enteroendocrine L cells. Studies conducted in humans, in rodent models, and in vitro indicate that GLP-2 is secreted in response to the presence of molecules in

High-protein and acidogenic diets induce hypercalciuria. Foods or supplements with excess sulfur-containing amino acids increase endogenous sulfuric acid production and therefore have the potential to increase calcium excretion and alter bone metabolism. In this study, effects of an amino
