The aim of this study was to determine body composition influence on cardiorespiratory fitness and metabolic markers in physically inactive individuals with insulin resistance (IR). Nineteen overweight obese (body mass index [BMI] 25.0–29.9 kg·m−2; ≥ 30.0 kg·m−2, respectively) patients diagnosed IR (5 men 14 women; age: 32.74 ± 10.07 years; BMI: 32.5 4.60 kg·m−2). included BMI, fat mass, fat-fr...

OBJECTIVE Body mass index (BMI) is more commonly used than waist circumference as a measure of adiposity in clinical and research settings. The purpose of this study was to compare the associations of BMI and waist circumference with cardiorespiratory fitness. METHODS In a cross-sectional study of 403 healthy men and women aged 50 ± 8.8 years, BMI and waist circumference were measured. Cardio...

AIM To determine the relationship between body mass index (BMI) and predicted values of VO2max estimated by UKK test for the first degree of obesity. METHODS The participants were included in three groups of ten male subjects each, of different ages and different physical condition, randomly selected from the general population of the city of Kragujevac. BMI was determined first, and then the...

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO2max) based on nonexercise (N-EX) data. All participants (N = 100), ages 18-65 years, successfully completed a maximal graded exercise test (GXT) to assess VO2max (M = 39.96 mL x kg(-1) x min(-1), SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gende...

AIM The purpose of this study was to assess the indirect calculation of VO2max using ACSM's equation for Bruce protocol in athletes of different sports and to compare with the directly measured; secondly to develop regression models predicting VO2 max in athletes. METHODS Fifty five male athletes of national and international level (mean age 28.3 ± 5.6 yrs) performed graded exercise test with...

PURPOSE Maximum oxygen uptake (VO2max) is known to be influenced by life-style factors, such as exercise and smoking. We aimed to further test the hypothesis that, besides these, work form also contributes to increase VO2max among workers. METHOD Three thousand six hundred and forty eight male workers with age 38.3 +/- 12.1 and 1,575 female workers with age 35.6 +/- 11.1, ranging from 20-year...

High levels of cardiovascular fitness (CRF) and physical activity (PA) are associated with decreased mortality and risk to develop metabolic diseases. The independent contributions of CRF and PA to metabolic disease risk factors are unknown. We tested the hypothesis that runners who run consistently >50 km/wk and/or >2 marathons/yr for the last 5 years have superior metabolic fitness compared t...

Objective The effects of regular exercise on the health promotion of patients with type 2 diabetes mellitus (T2DM) have been well documented. The present study investigated the long-term effects of regular exercise training on biological indicators among these patients. Methods In this quasi-experimental trial with pretest-post-test design, 65 patients with T2DM aged 33-69 years (experiment (...

This cross-sectional study evaluated the relationships between anthropometric and aerobic fitness (rate of perceived exertion [RPE] predicted maximal oxygen uptake [VO2max]) among 228 participants (age: 23.78±4.42 years). RPE VO2max were determined during cycle ergometer exercise test. Data also obtained for height, weight, body mass index (BMI), hip waist (WC) circumferences. analysis reveale...
