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 ...

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.

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.

Dietary Nitrate and Physical Performance
Annual Review of Nutrition, 2018Nitric oxide (NO) plays a plethora of important roles in the human body. Insufficient production of NO (for example, during older age and in various disease conditions) can adversely impact health and physical performance. In addition to its endogenous production through the oxidation of l-arginine, NO can be formed nonenzymatically via the reduction ...

Growth hormone and physical performance
Trends in Endocrinology & Metabolism, 2011There has been limited research and evidence that GH enhances physical performance in healthy adults or in trained athletes. Even so, human growth hormone (GH) is widely abused by athletes. In healthy adults, GH increases lean body mass, although it is possible that fluid retention contributes to this effect.

PASSCLAIM - Physical performance and fitness
European Journal of Nutrition, 2003The aim of the EC Concerted Action PASSCLAIM was to develop a set of methods and procedures for assessing the scientific support for function-enhancing and health-related claims for foods and food components. This paper presents a critical review of the existing methods to evaluate the different aspects of physical performance and fitness needed to ...

There is abundant evidence that aging makes elderly people weaker, slower, less powerful and also causes a deterioration in their balance and reaction time [1-3]. Nevertheless, it is still difficult to make a clear distinction between the effects of aging, deconditioning and disease with respect to decreased performance and health status.
