Vitamin D and Physical Performance
Sports Medicine, 2013Vitamin D is an essential nutrient obtained from the diet and exposure to sunlight. Roles for vitamin D have been established in the function of the cardiovascular, immune, and musculoskeletal systems. An electronic database search was conducted using EMBASE (1967 to August 2012), MEDLINE (1966 to August 2012), SPORTDiscus™ (1975 to August 2012), and ...

Performance of physical tasks in pregnancy
Ergonomics, 1992Two hundred women in the third trimester of a first pregnancy were interviewed, and 50 of them were interviewed again at 4 months post partum. They were asked whether they experienced greater current difficulty in performing 46 common tasks than they did before pregnancy and were asked to grade their responses.

Protein and physical performance
Current Opinion in Clinical Nutrition and Metabolic Care, 1999Important advances have been made in the understanding of the regulation of protein metabolism, which are of relevance to those interested in maximizing muscle performance in sport and aging. The use of 24 h amino acid infusion studies, the development of methods to measure skeletal muscle fractional breakdown rate and the fractional synthetic rate of ...

Nutrition and Physical Performance
The Physician and Sportsmedicine, 1982In brief Physical training increases the nutrient requirements of total calories, proportion of carbohydrates, thiamine, riboflavin, niacin, iron, water, salt, and perhaps chromium. Conscious adjustments must usually be made in total calories, carbohydrates, water, salt, and iron consumption to maintain optimal performance levels.

Antioxidants and physical performance
Critical Reviews in Food Science and Nutrition, 1995Performance of strenuous physical activity can increase oxygen consumption by 10- to 15-fold over rest to meet energy demands. The resulting elevated oxygen consumption produces an "oxidative stress" that leads to the generation of free radicals and lipid peroxidation.

Hydration and Physical Performance
Journal of the American College of Nutrition, 2007There is a rich scientific literature regarding hydration status and physical function that began in the late 1800s, although the relationship was likely apparent centuries before that. A decrease in body water from normal levels (often referred to as dehydration or hypohydration) provokes changes in cardiovascular, thermoregulatory, metabolic, and ...

Physical Exertion and Mental Performance
Ergonomics, 1973The problem of why people in a state of fatigue make wrong decisions prompted a series of laboratory experiments of which two are described. Subjects pedalled a bicycle ergometer for varying periods of time and were tested for mental performance after different amounts of physical exertion.
