OBJECTIVE Comprehensively and objectively assess physical activity, aerobic fitness and body fat in adolescents and young adults with myelomeningocele and to investigate their relationships. DESIGN Cross-sectional study. SUBJECTS Fifty-one persons (26 males) with myelomeningocele aged 21.1 (standard deviation) 4.5) years. METHODS Physical activity was measured with an accelerometry-based ...

High aerobic fitness is consistently associated with a favorable metabolic health profile in children. However, measurement of oxygen uptake, regarded as the gold standard for evaluating aerobic fitness, is often not feasible. Thus, the aim of the present study was to perform a clinical validation of three measures of aerobic fitness (peak oxygen consumption [VO2peak] and time to exhaustion [TT...

We used bilateral phrenic nerve stimulation (BPNS; at 1, 10, and 20 Hz at functional residual capacity) to compare the amount of exercise-induced diaphragm fatigue between two groups of healthy subjects, a high-fit group [maximal O2 consumption (VO2max) = 69.0 +/- 1.8 ml.kg-1.min-1, n = 11] and a fit group (VO2max = 50.4 +/- 1.7 ml.kg-1.min-1, n = 13). Both groups exercised at 88-92% VO2max for...

THYFAULT, J.P. and E.M. MORRIS. Intrinsic (genetic) aerobic fitness impacts susceptibility for metabolic disease. Exerc. Sport Sci. Rev., Vol. 45, No. 1, pp. 7–15, 2017. Low-capacity runner (LCR) and high-capacity runner (HCR) rat strains are divergent for running capacity and aerobic fitness. The LCR rats are susceptible to obesity, insulin resistance, and fatty liver whereas the HCR are prote...

Aerobic power (VO2max) is an important indicator of the health and physical fitness. Executive problems in direct VO2max measurement has led to developing sub-maximal aerobic power prediction equations. The purpose of present study was to develop native aerobic power prediction equation based on 6-Minute Walk Test (6MWT) and body composition indices in children. In 192 healthy children (8 to 12...

OBJECTIVE We examined secular trends in physical fitness and BMI status in 8- to 9-year-old Greek children during an 11-year period (1997-2007). METHODS Population data derived from a yearly health survey performed in over 85% of Greek schools. Anthropometric measurements and physical fitness tests from 651,582 children were analyzed. The gender- and age-specific BMI cut-off points by the Int...

AIM The purpose of this study was to determine whether physical fitness is linked to academic success in middle school students. METHODS The FITNESSGRAM test battery assessed students (n = 838) in the five components of health-related fitness. The Illinois Standardized Achievement Test (ISAT) was used to assess academic achievement in reading and math. RESULTS The largest correlations were ...

PURPOSE We investigated the relationship between aerobic fitness and sustained attention capacity by comparing task performance and brain function, by means of event-related potentials (ERP), in high- and low-fit young adults. METHODS Two groups of participants (22 higher-fit and 20 lower-fit) completed a 60-min version of the Psychomotor Vigilance Task (PVT). Behavioral (i.e., reaction time)...

Oxygen metabolism is a strong predictor of the general health and fitness of an organism. In this study, we hypothesized that a divergence in intrinsic aerobic fitness would co-segregate with susceptibility for cardiovascular dysfunction. To test this hypothesis, cardiac function was assessed in rats specifically selected over nineteen generations for their low (LCR) and high (HCR) intrinsic ae...

purpose to translate long form, interview-administered international physical activity questionnaire (ipaq) from english to persian and evaluate its validity, reliability and reproducibility. methods a forward-backward translation procedure was followed to develop the persian version of the ipaq. a total of 218 respondents (53.7% women, aged 22–76 yr) completed the persian version in tehran, ir...
