Results Using multiple linear regression, a model was produced where significant predictors of VO2max (p < 0.05) included estimated body fat percentage from sum of three skinfolds (p < .001) and BMI (p = .024). The generalized equation (R = .741, R2 = .549, SEE = 7.10) derived from the model to predict VO2max was: 72.32 + (-.949 × %fat from skinfolds) – (.392 × BMI). Variables excluded (p > 0.0...

We have previously shown that cardiorespiratory fitness predicts increasing fat mass during growth in white and African-American youth, but limited data are available examining this issue in Hispanic youth. Study participants were 160 (53% boys) overweight (BMI>or=85th percentile for age and gender) Hispanic children (mean+/-s.d. age at baseline=11.2+/-1.7 years). Cardiorespiratory fitness, ass...

The aim of this study was to investigate the responses of creatine kinase (CK) and lactate dehydrogenase (LDH) after performing different resistance and aerobic exercise protocols. Twelve recreationally trained men (age, 23.2 ± 5.6 years; body mass, 84.3 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and BMI, 26.3 ± 2.3 kg·m2) volunteered to participate in this study. All subjects were randomly assigne...

BACKGROUND The purpose was to develop new maximal oxygen uptake (VO2max) prediction models using a perceptually regulated 3-minute walk test. METHODS VO2max was measured with a maximal incremental cycle test in 283 Japanese adults. A 3-minute walk test was conducted at a self-regulated intensity corresponding to ratings of perceived exertion (RPE) 13. RESULTS A 3-minute walk distance (3MWD)...

UNLABELLED Skeletal muscle-derived interleukin-6 (IL-6) is a pleiotropic cytokine which regulates body metabolism during strenuous physical exercise. OBJECTIVE The effect of a potentially functional single nucleotide polymorphism (SNP) -174G/C of the IL6 gene (rs1800795) promoter was examined on maximal oxygen uptake (VO2max), body mass index (BMI) and plasma IL-6 levels in response to physic...

This investigation aimed to determine if groupings based upon sum of skinfold thickness (SF) would reflect the differences in heart rate variability (HRV) measured for up to 30-minutes following maximal exercise, and to determine the extent in variation in post-exercise HRV that could be accounted for between the following independent variables: SF, body mass index (BMI) and maximal oxygen cons...

BACKGROUND Obesity is a growing health issue in Canada and the identification of the determinants of obesity is important for the development of prevention strategies. The purpose of this investigation was to determine the relationships between physical activity, cardiorespiratory fitness, body mass index (BMI), and the development of future obesity. METHODS The sample included 459 adults (18...
