Another limitation of our study was that we estimated, rather than directly measured, residual lung volume during underwater weighing. To standardize these measurements, we developed a prediction model for hydrostatistically determining percentage body fat from percentage fat (%fat) estimated by Σ7 skinfold thicknesses from the 5090 men who provided both Σ7 skinfold thicknesses and hydrostatic weighing data. The purpose of this study was to measure the influence of diet, exercise, or both on body composition and cardiorespiratory fitness in obese women. Body composition, however, is not a great predictor of performance. Body composition is the percentage of bone, muscle, water and fat you carry. Blair SN, Kohl HW, Barlow CE, Paffenbarger RS Jr, Gibbons LW, Macera CA. Body composition is not something you do, like 10 push-ups or 50 sit-ups. Ninety-one obese subjects were randomized into one of four groups: diet (D) (4.19-5.44 MJ or 1,200-1,300 kcal/day), exercise (E) (five 45-min sessions at 78.5+/-0.5% maximum heart rate), exercise and diet (ED), and controls (C). Body composition addresses fat mass and fat-free mass in which the latter consists of … All subjects gave their informed, written consent for the medical evaluation and subsequent registration in the follow-up study. However, the influence of body mass on SBP, given the lack of relationship between SBP and BMI or percentage body fat, remains an anomaly within these results. The 95% CIs were calculated for each RR. Finally, we had only a one-time assessment of the exposure variables of cardiorespiratory fitness and body composition, and we do not know the extent to which these characteristics might have changed during follow-up. (WC) measured in addition to body fat percentage (FM%) by dual-energy x-ray absorptiometry (DXA). We observed a direct relation between body fatness and all-cause and CVD mortality. The relative risks (RRs) of all-cause and CVD mortality were estimated after adjustment for age and examination year and further adjustment for cigarette smoking, alcohol intake, and parental history of IHD. Cardiorespiratory fitness (CRF) refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. The results of the present research showed that Genetics Factors may play an important role in body composition And cardiorespiratory fitness of parents and his/here Children,and suggest that Environmental factors can be a more significant than heredity Parameters. We also calculated V̇O2max in mL•kg FFM−1•min−1 and classified men in the lowest quartile of oxygen uptake in each age group as physically unfit, and all others as physically fit. Obesity: preventing and managing the global epidemic. Cox proportional hazards regression analyses, adjusted for age and examination year, showed that fit men had lower death rates than did their unfit counterparts within lean, normal, and obese categories. Design: This was an observational cohort study. The influence of exposure distributions may be even greater when examining joint associations of adiposity and physical activity ... Cardiorespiratory fitness, body composition, and all-cause and cardiovascular disease mortality in men. However, changes in the exposure variables during follow-up would cause misclassification and would be likely to lead to underestimates of RRs. Results: After adjustment for age, examination year, cigarette smoking, alcohol intake, and parental history of ischemic heart disease, unfit (low cardiorespiratory fitness as determined by maximal exercise testing), lean men had double the risk of all-cause mortality of fit, lean men (relative risk: 2.07; 95% CI: 1.16, 3.69; P = 0.01). Epub 2018 Jul 5. The purpose of this study was to measure the influence of diet, exercise, or both on body composition and cardiorespiratory fitness in obese women. Morrow JR, Jackson AS, Bradley PW, Hartung GH. OBJECTIVE The relationship between cardiorespiratory fitness (CRF) and metabolic syndrome (MetS) is well known, although the extent to which body weight may act as a confounder or mediator in this relationship is uncertain. Of this explained variance, majority was explained by percent of total calories from carbohydrate (2.4%, P<0.01). We examined the health effects of body composition among 21925 men after taking cardiorespiratory fitness into account. Numbers above or below the bars represent the number of deaths. Kuczmarski RJ, Flegal KM, Campbell SM, Johnson CL. answers Well Losing weight, building muscle, increasing endurance Describe the factors that influence the level of cardiorespiratory fitness a person is able to achieve. Lee et al. Similarly, unfit men with low waist girths (<87 cm) had greater risk of all-cause mortality than did fit men with high waist girths (> or =99 cm). Alcohol use, cigarette smoking habit, and parental history of ischemic heart disease (IHD; either parent died of IHD) were assessed by self-report on a medical history questionnaire. Seidell JC, Oosterlee A, Deurenberg P, Hautvast JGA, Ruijs JHJ. How Exercise Affects Your Body's Composition. Nonetheless, the densitometry and skinfold-thickness estimates of body composition were likely to be more accurate measures of body fatness than BMI or height-weight indexes. Current smokers were further classified as smoking <20, 20 to <40, and ≥40 cigarettes/d.  |  Ninety-one obese subjects were randomized into one of four groups: diet (D) (4.19–5.44 MJ or 1,200–1,300 kcal/day), exercise (E) (five 45-min sessions at 78.5 ± 0.5% maximum heart rate), exercise and diet (ED), and controls (C). Fat mass, fat-free mass, and relative risks (RR) of all-cause and cardiovascular disease (CVD) mortality by cardiorespiratory fitness categories in men; □, fit; ▪, unfit. We also examined the relations of cardiorespiratory fitness, fat mass, and FFM to all-cause and CVD mortality (Figure 4). Total treadmill endurance time was used as an index of aerobic power; time on treadmill with this protocol correlated highly (r = 0.92) with maximal oxygen uptake (V̇O2max) (24).

Exercise in health and disease: evaluation and prescription for prevention and rehabilitation. Central fatness and risk of all cause mortality: systematic review and dose-response meta-analysis of 72 prospective cohort studies. Effect of Vitamin D supplementation on body composition and cardiorespiratory fitness in overweight men-a randomized controlled trial. COVID-19 is an emerging, rapidly evolving situation. NIH Therefore, the true associations between fitness or body fatness and mortality may have actually been stronger than indicated by our results. Although there is a strong direct relation between BMI and mortality (27), there has been little research on the relation between measured body fatness and mortality (16). There were 162 deaths (40 from CVD, 54 from cancer, and 68 from other causes) during an average of 5.6 y of follow-up (78008 man-years of observation) in the subgroup of 14043 men who had waist girth assessed at baseline. We are grateful for the guidance of the Scientific Advisory Board of the Cooper Institute for Aerobics Research. Correlation of physical fitness with psychological well-being, stress, and depression in Korean adults. Results: Fifty two firefighters participated (92.3% men). In addition, men who failed to achieve ≥85% of their age-predicted maximal heart rate on the maximal exercise test were excluded; this should have eliminated men who did not have a history of disease but were not feeling well as a result of an undiagnosed condition. including models for cardiorespiratory fitness, diet, and body composition. ...

As … The effect of all these exclusion criteria was to minimize the possible bias of baseline subclinical disease. Fuel Utilization. Relationship between low cardiorespiratory fitness and mortality in normal-weight, overweight, and obese men. All statistical procedures were performed with SAS software (26). 1999 Oct 27;282(16):1547-53. doi: 10.1001/jama.282.16.1547. During an average of 8 y of follow-up (176742 man-years), there were 428 deaths: 144 from CVD, 143 from cancer, and 141 from other causes. We examined the effect of low-volume HIIT versus a non-exercising control and moderate-intensity continuous training (MICT) on body composition and cardiorespiratory fitness in normal weight, overweight and obese adults. Instead of using weight as a measurement of your health progress, use body composition to determine the amount of change in fat and muscle mass when you exercise. Body fatness categories were, in percentage body fat, lean (< 16.7%), normal (16.7% to < 25.0%), and obese (≥ 25.0%). Prog Cardiovasc Dis. Cardiorespiratory fitness refers to the abil-ity of the heart to pump blood through the body efficiently. After adjustment for age, examination year, cigarette smoking, alcohol intake, and parental history of ischemic heart disease, unfit (low cardiorespiratory fitness as determined by maximal exercise testing), lean men had double the risk of all-cause mortality of fit, lean men (relative risk: 2.07; 95% CI: 1.16, 3.69; P = 0.01). Proportional hazards regression was used to examine the associations among cardiorespiratory fitness, body fatness, and all-cause and CVD mortality (25). Results: THE EFFECT OF MENOPAUSAL TRANSITION ON BODY COMPOSITION, CARDIOMETABOLIC RISK FACTORS, PHYSICAL ACTIVITY AND CARDIORESPIRATORY FITNESS Joseph Abdulnour Thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfillment of the requirements for the Doctorate in Philosophy in Human Kinetics School of Human Kinetics Body weight and stature were measured with a standard physician's scale and stadiometer. Our database is unique, with measures of body composition and maximal exercise test data on a large sample of men. After multivariate adjustment for age, examination year, cigarette smoking, alcohol intake, and parental history of IHD, we observed that fit, lean men had the lowest CVD mortality, and that unfit, obese men had the highest. This was an observational cohort study. Higher fat mass may indicate better oxidation of fat as fuel, thus impacting RQ. All-cause and CVD death rates per 10000 man-years (for which a man-year is 1 man followed for 1 y) of follow-up, adjusted for age and examination year, were calculated across body fatness and waist circumference categories. Rather, it mainly indicates overweight for height but does not discriminate between fat mass and fat-free mass (FFM). Obese men should be encouraged to increase their cardiorespiratory fitness by engaging in regular, moderate-intensity physical activity; this should benefit them even if they remain overweight. All-cause and CVD death rates per 10000 man-years of follow-up, adjusted for age and examination year across body fatness categories, are shown in Figure 1. Body fatness and relative risks (RRs) of all-cause and cardiovascular disease (CVD) mortality by cardiorespiratory fitness categories in men: □, fit; ▪, unfit. We also observed results similar to the analyses presented above when the men were stratified by waist circumference. Hellénius ML, de Faire U, Berglund B, Hamstern A, Krakau I. Katzel LI, Bleecker ER, Colman EG, Rogus EM, Sorkin JD, Goldberg AP. Body composition represents total lean mass and total fat mass. ance, flexibility, and body composition (the ratio of fat and lean body tissue). We also cross-tabulated by cardiorespiratory fitness levels across fat mass, FFM, and waist circumference categories. The all-cause mortality rate of fit, obese men was not significantly different from that of fit, lean men. All-cause and CVD death rates directly increased with larger sizes of waist girth, although the trends were not significant (Figure 5). Background: Cardiorespiratory fitness and body fatness are both related to health, but their interrelation to all-cause and cardiovascular disease (CVD) mortality is unknown. SAS/STAT software: the PHREG procedure, version 6. Body composition is a special term used in physical fitness that measures the percentage of fat, muscle, water and bone found in the human body. answers Well Losing weight, building muscle, increasing endurance Describe the factors that influence the level of cardiorespiratory fitness a person is able to achieve. Numbers atop the bars represent the number of deaths. Anthropometric measurement of body composition by whole-body dual-energy X-ray absorptiometry and measures related to MetS, including waist circumference, triglyceride level, high-density lipoprotein cholesterol level, blood pressure, glucose level, and physical fitness components, were assessed. Lastly, cardiorespiratory fitness (CRF) has not been explored. Regular exercise is the main cause to improve body composition and cardiovascular fitness. Physiol Behav. Unfit men had a higher risk of all-cause and CVD mortality than did fit men in all fat and fat-free mass categories. We tested differences between groups with a two-factor analysis of variance (continuous data) or log linear models (categorical data). Methods: Seven male and nine female subjects over 21 years old completed the Alcohol Use Disorders Identification (AUDIT), a maximal treadmill test to measure maximal oxygen Supported in part by US Public Health Service research grant AG06945 from the National Institute on Aging, Bethesda, MD, and Polar Electro Oy, Kempele, Finland.
