BACKGROUND Aerobic capacity tests are important to evaluate exercise programs and to encourage individuals to have a physically active lifestyle. Submaximal tests, if proven valid and reliable could be used for estimation of maximal oxygen uptake (VO2max). The purpose of the study was to examine the criterion-validity of the submaximal self-monitoring Fox-walk test and the submaximal Åstrand cy...

The aim of this study was to investigate the association between cardiorespiratory fitness and gut microbiota composition in premenopausal women. The participants consisted of 71 premenopausal Finnish women (aged 19-49 years). Gut microbiota were analyzed using flow cytometry, 16S rRNA gene hybridization and DNA-staining. Maximum oxygen uptake (VO2max) was assessed by respiratory gas analyzer a...

BACKGROUND Fisherwomen contribute significantly to the coastal economy of Eastern India; however, data about their physical fitness and weight status are scant. OBJECTIVES The present cross-sectional study was designed to investigate cardiorespiratory fitness and weight status of fisherwomen, which may be influenced by their occupational workload, using morphometric and anthropometric measure...

As studying with population carrying no classical cardiovascular risk factors seems to be an advantage in isolating effects of regular exercise on endothelial functions, inflammatory and thrombotic activity; the present study was designed to evaluate the clear effects of long-term regular exercise in middle-aged, healthy men. A total of 32 regularly exercising (three times per week, 12.8 ± 6.8 ...

Assessment of physical condition (PC) is utmost interest for physicians and specifically medical oncologists, since it highly informative the process therapeutic decision-making. PC ability to carry out daily tasks with vigour alertness, without undue fatigue ample energy engage in leisure time pursuits meet above-average stresses encountered emergency situations. The concept includes different...

BACKGROUND Maximal oxygen uptake (VO2max), an assessment of cardiorespiratory fitness, is regularly used as the primary outcome in exercise interventions. Many criteria have been suggested for validating such tests-most commonly, a plateau in oxygen consumption. The current study investigated the proportion of inactive individuals who reached a plateau in oxygen uptake and who achieved a valid ...

BACKGROUND The purpose of this study was to determine the age-related loss of health-related physical fitness and normative data in healthy population women aged 20-60 years old of Tehran, Iran. METHODS In this cross-sectional study, 1000 healthy women aged 20-60 years old were randomly selected from northern, southern, eastern, western and center regions of Tehran. Cardiovascular fitness was...

OBJECTIVE Left ventricular ejection fraction (LVEF) and maximal functional capacity (VO2max) have both been shown to be related to a poor long-term survival in Chagas' disease patients. The aim of this study was to estimate the potential association of VO2max, LVEF, and NYHA functional class in patients with Chagas' disease cardiomyopathy. METHODS One hundred four male patients, aged 40.3+/-9...
