Is Less Sedentary Behavior, More Physical Activity, or Higher Fitness Associated with Sleep Quality? A Cross-Sectional Study in Singapore
Physical activity/exercise training programs that aim to improve CRF may be useful in lowering the odds or poor SQ in working adults
Sedentary Behavior, Exercise, and Cardiovascular Health
Sedentary behavior and physical inactivity are among the leading modifiable risk factors worldwide for cardiovascular disease and all-cause mortality. The promotion of physical activity and exercise training (ET) leading to improved levels of cardiorespiratory fitness is needed in all age groups, race, and ethnicities and both sexes to prevent many chronic diseases, especially cardiovascular disease. In this state-of-the-art review, we discuss th…
Daily step count and all-cause mortality in a sample of Japanese elderly people
This study suggested that a high daily step count is associated with a lower risk of all-cause mortality in physically independent Japanese elderly people
Social Participation Modifies the Effect of a Structured Physical Activity Program on Major Mobility Disability Among Older Adults
Our findings suggest that baseline social participation is an important factor for the success of a PA intervention aimed at delaying mobility disability
Cross-sectional and longitudinal associations between different exercise types and food cravings in free-living healthy young adults
Importance of Assessing Cardiorespiratory Fitness in Clinical Practice
Mounting evidence has firmly established that low levels of cardiorespiratory fitness (CRF) are associated with a high risk of cardiovascular disease, all-cause mortality, and mortality rates attributable to various cancers. A growing body of epidemiological and clinical evidence demonstrates not only that CRF is a potentially stronger predictor of mortality than established risk factors such as smoking, hypertension, high cholesterol, and type 2…
Provider Advice and Women’s Intentions to Meet Weight Gain, Physical Activity, and Nutrition Guidelines During Pregnancy
Is nutrient intake associated with physical activity levels in healthy young adults
Objective Both physical activity (PA) and diet are important contributors to health and well-being; however, there is limited information on the association of these behaviours and whether observed associations differ by weight. The present study aimed to evaluate whether nutrient intake is associated with PA and if this association varies by weight in young adults. Design Cross-sectional study to analyse the association between PA and nutrient i…
Patient and Provider Perceptions of Weight Gain, Physical Activity, and Nutrition Counseling during Pregnancy
Effect of Structured Physical Activity on Prevention of Major Mobility Disability in Older Adults
IMPORTANCE: In older adults reduced mobility is common and is an independent risk factor for morbidity, hospitalization, disability, and mortality. Limited evidence suggests that physical activity may help prevent mobility disability; however, there are no definitive clinical trials examining whether physical activity prevents or delays mobility disability. OBJECTIVE: To test the hypothesis that a long-term structured physical activity program is…
Associations between physical activity and sedentary time on components of metabolic syndrome among adults with HIV
Recent data show that people living with HIV/AIDS (PLWHA) are at a greater risk of cardiovascular disease (CVD), which could possibly be explained by an increased prevalence of metabolic syndrome (MetSyn) due to the known toxicities associated with antiretroviral therapy (ART). The purpose of this study is to examine the relationships between physical activity (PA) and components of MetSyn in a sample of PLWHA taking ART. A total of 31 males and …
Cardiorespiratory fitness, body mass index, and cancer mortality
These results suggest that high CRF is associated with lower cancer mortality in a Japanese population of men with low average BMI

Effect of physical inactivity on major non-communicable diseases worldwide
How many steps/day are enough? for children and adolescents
Worldwide, public health physical activity guidelines include special emphasis on populations of children (typically 6-11 years) and adolescents (typically 12-19 years). Existing guidelines are commonly expressed in terms of frequency, time, and intensity of behaviour. However, the simple step output from both accelerometers and pedometers is gaining increased credibility in research and practice as a reasonable approximation of daily ambulatory …
How many steps/day are enough? for adults
Physical activity guidelines from around the world are typically expressed in terms of frequency, duration, and intensity parameters. Objective monitoring using pedometers and accelerometers offers a new opportunity to measure and communicate physical activity in terms of steps/day. Various step-based versions or translations of physical activity guidelines are emerging, reflecting public interest in such guidance. However, there appears to be a …
Physical Activity for Health
Physical activity improves health. Different types of activity promote different types of physiologic changes and different health outcomes. A curvilinear reduction in risk occurs for a variety of diseases and conditions across volume of activity, with the steepest gradient at the lowest end of the activity scale. Some activity is better than none, and more is better than some. Even light-intensity activity appears to provide benefit and is prefe…
Trends over 5 Decades in U.S. Occupation-Related Physical Activity and Their Associations with Obesity
BACKGROUND: The true causes of the obesity epidemic are not well understood and there are few longitudinal population-based data published examining this issue. The objective of this analysis was to examine trends in occupational physical activity during the past 5 decades and explore how these trends relate to concurrent changes in body weight in the U.S. METHODOLOGY/PRINCIPAL FINDINGS: Analysis of energy expenditure for occupations in U.S. priv…
Association between neighborhood walkability, cardiorespiratory fitness and body-mass index
Appropriate Physical Activity Intervention Strategies for Weight Loss and Prevention of Weight Regain for Adults
Overweight and obesity affects more than 66% of the adult population and is associated with a variety of chronic diseases. Weight reduction reduces health risks associated with chronic diseases and is therefore encouraged by major health agencies. Guidelines of the National Heart, Lung, and Blood Institute (NHLBI) encourage a 10% reduction in weight, although considerable literature indicates reduction in health risk with 3% to 5% reduction in we…
Physical Activity and Public Health in Older Adults

PARTICIPANTS: A panel of scientists with expertise in public health, behavioral science, epidemiology, exercise science, medicine, and gerontology. EVIDENCE: The expert panel reviewed existing consensus statements and relevant evidence from primary research articles and reviews of the literature. PROCESS: After…
Physical Activity and Public Health
In 1995 the American College of Sports Medicine and the Centers for Disease Control and Prevention published national guidelines on Physical Activity and Public Health. The Committee on Exercise and Cardiac Rehabilitation of the American Heart Association endorsed and supported these recommendations. The purpose of the present report is to update and clarify the 1995 recommendations on the types and amounts of physical activity needed by healthy …

Physical Activity Assessment Methodology in the Five-City Project1
Previous measures of physical activity for epidemiologic studies were considered inadequate to meet the needs of a community-based health education trial. Therefore, new methods of quantifying the physical activity habits of communities were developed which are practical for large health surveys, provide information on the distribution of activity habits in the population, can detect changes in activity over time, and can be compared with other e…

Physical Fitness and All-Cause Mortality
We studied physical fitness and risk of all-cause and cause-specific mortality in 10 224 men and 3120 women who were given a preventive medical examination. Physical fitness was measured by a maximal treadmill exercise test. Average follow-up was slightly more than 8 years, for a total of 110 482 person-years of observation. There were 240 deaths in men and 43 deaths in women. Age-adjusted all-cause mortality rates declined across physical fitnes…
Influences of Cardiorespiratory Fitness and Other Precursors on Cardiovascular Disease and All-Cause Mortality in Men and Women
OBJECTIVE: To quantify the relation of cardiorespiratory fitness to cardiovascular disease (CVD) mortality and to all-cause mortality within strata of other personal characteristics that predispose to early mortality. DESIGN--Observational cohort study. We calculated CVD and all-cause death rates for low (least fit 20%), moderate (next 40%), and high (most fit 40%) fitness categories by strata of smoking habit, cholesterol level, blood pressure, …
Comparison of a dietary record using reported portion size versus standard portion size for assessing nutrient intake
Objective Because the percentage of missing portion sizes was large in the Aerobics Center Longitudinal Study (ACLS), careful consideration of the accuracy of standard portion sizes was necessary. The purpose of the present study was to investigate the consequences of using standard portion sizes instead of reported portion sizes on subjects' nutrient intake. Methods In 2307 men and 411 women, nutrient intake calculated from a 3-day dietary recor…
Is physical activity or physical fitness more important in defining health benefits?
PURPOSE: We addressed three questions: 1) Is there a dose-response relation between physical activity and health? 2) Is there a dose-response relation between cardiorespiratory fitness and health? 3) If both activity and fitness have a dose-response relation to health, is it possible to determine which exposure is more important? METHODS: We identified articles by PubMed search (restricted from 1/1/90 to 8/25/00) using keywords related to physica…
