Dietary measures of physical activity

摘要: The relationships between cardiovascular fitness, body fatness, and the number of calories required to maintain stable weight over a baseline period three weeks were studied in 21 healthy obese males aged 20-44 years who participated controlled feeding experiment at Division Epidemiology (formerly Laboratory Physiological Hygiene) School Public Health, University Minnesota, August 1980-June 1981. statistically significant found actually consumed per kg (kcal/kg) fatness (r = -0.79, p 0.001), consumer physical work capacity (VO2 max) 0.76, 0.001). Using quartiles, caloric intake VO2 max decreased progressively as increased through its four quartiles. These also seen when reported from three-day food record was used; however, magnitude attenuated. On other hand, unadjusted for weight, whether actual or reported, unrelated both max. To determine these hold true less subjects, authors have analyzed compared their results with data previously experiments done Minnesota. Correlations fat indices similar studies. Therefore, conclude that relatively young, healthy, sedentary wide range observed adjusted reflect habitual activity. confirm epidemiologic observations an inverse relationship provide rationale using measure long-term Thus, bolster interpretation mortality reflects positive health effect This index may be particularly useful large population
