Physical activity in free-living, overweight white and black women:divergent responses by race to diet-induced weight loss
Overweight obesity weight loss body composition energy expenditure energy economy physical activity exercise African American women
2016/12/19
Background: Black women are at greater risk of obesity than are white women, perhaps because of their lower levels of physical activity.Objective: We compared free-living activity energy exp...
Low physical activity reduces total energy expenditure in women with rheumatoid arthritis:implications for dietary intake recommendations
Rheumatoid arthritis energy metabolism doubly labeled water physical activity total energy expenditure women
2016/12/19
Background: Rheumatoid arthritis (RA) causes cachexia, a metabolic response characterized by loss of muscle mass and elevated resting energy expenditure (REE). However, energy expenditure in phys...
Longitudinal changes in body composition in older men and women:role of body weight change and physical activity
Aging weight change sarcopenia fat mass fat-free mass sports recreational activity
2016/12/19
Background: Estimates of body-composition change in older adults are mostly derived from cross-sectional data.Objective: We examined the natural longitudinal patterns of change in fat-free m...
Associations of body mass index and obesity with physical activity,food choices,alcohol intake,and smoking in the 1982–1997 FINRISK Studies
Obesity population studies FINRISK Studies lifestyle physical activity food choices body mass index
2016/12/17
Background: Recent increases in the prevalence of obesity worldwide are suggested to be caused largely by an environment that promotes sedentariness and excessive food intake.Objective: We i...
Comparison of energy expenditure estimates from doubly labeled water,a physical activity questionnaire,and physical activity records
Exercise energy intake Stanford 7-d physical activity questionnaire physical activity records physical activity recall doubly labeled water basal metabolic rate men
2016/12/17
Background: Various methods are used by epidemiologists to estimate the energy cost of physical activity; these include physical activity records and recalls. However, there is limited validation...
Habitual physical activity,anabolic hormones,and potassium content of fat-free mass in postmenopausal women
Total body potassium fat-free mass physical activity aging postmenopausal women estradiol insulin-like growth factor I sarcopenia
2016/12/17
Background: Total body potassium (TBK) is known to decline throughout adulthood. The relations between physical activity, age, anabolic hormones, and TBK have rarely been considered.Objective:...
Magnesium, zinc, and chromium nutriture and physical activity
Trace elements endurance muscle strength, physical activity nutritional status mineral supplements magnesium, zinc chromium
2016/6/7
Magnesium, zinc, and chromium are mineral
elements required in modest amounts to maintain health and
optimal physiologic function. For physically active persons, adequate
amounts of these micronutr...
Effect of physical activity on thiamine, riboflavin, and vitamin B-6 requirements
Thiamine riboflavin vitamin B-6 exercise, physical activity nutrient requirements dietary reference intakes, recommended dietary allowances RDA DRI
2016/6/7
Because exercise stresses metabolic pathways
that depend on thiamine, riboflavin, and vitamin B-6, the requirements
for these vitamins may be increased in athletes and active
individuals. Theoretic...
Physical activity as a metabolic stressor
Exercise physical activity exertion nutrition, carbohydrate triacylglycerol protein synthesis hormone
2016/6/7
Both physical activity and diet stimulate
processes that, over time, alter the morphologic composition and
biochemical function of the body. Physical activity provides
stimuli that promote very spe...
Methodologic issues in measuring physical activity and physical fitness when evaluating the role of dietary supplements for physically active people
Physical activity exercise exercise training, physical fitness
2016/6/7
Physical activity and physical fitness are complex
entities comprising numerous diverse components that
present a challenge in terms of accurate, reliable measurement.
Physical activity can be clas...
Concurrent physical activity increases fat oxidation during the shift to a high-fat diet
Dietary fat fat oxidation physical activity, macronutrient oxidation young healthy men
2016/6/7
Background: It takes several days to adapt to a high-fat diet. In
an earlier study, we observed a large degree of interindividual
variation in the capacity to adapt to a high-fat diet. We hypothesiz...
The important role of physical activity in skeletal development: how exercise may counter low calcium intake
skeletal development calcium intake
2016/6/7
Skeletal development requires reasonable intakes of all the
nutrients required by bone tissue, but energy and protein are critical
for attainment of growth commensurate with hereditary determinants....
Energy expenditure and free-living physical activity in black and white women: comparison before and after weight loss
Overweight obesity weight loss body composition energy expenditure aerobic capacity
2016/6/7
Background: The prevalence of obesity is higher in black than
in white women. Differences in energy economy and physical
activity may contribute to this difference.
Objective: The objective of this...
