    ABSTRACT: Obesity increases the risk of asthma throughout life but the underlying mechanisms linking these all too common threats to child health are poorly understood. Acute bouts of exercise, aerobic fitness, and levels of physical activity clearly play a role in the pathogenesis and/or management of both childhood obesity and asthma. Moreover, both obesity and physical inactivity are associated with asthma symptomatology and response to therapy (a particularly challenging feature of obesity-related asthma). In this article, we review current understandings of the link between physical activity, aerobic fitness and the asthma-obesity link in children and adolescents (e.g., the impact of chronic low-grade inflammation, lung mechanics, and direct effects of metabolic health on the lung). Gaps in our knowledge regarding the physiological mechanisms linking asthma, obesity and exercise are often compounded by imprecise estimations of adiposity and challenges of assessing aerobic fitness in children. Addressing these gaps could lead to practical interventions and clinical approaches that could mitigate the profound health care crisis of the increasing comorbidity of asthma, physical inactivity, and obesity in children.

    ABSTRACT: Little is known about the effects of acute exercise on the cognitive functioning of children with cerebral palsy (CP). Selected cognitive functions were thus measured using a pediatric version of the Stroop test before and after maximal, locomotor based aerobic exercise in 16 independently ambulatory children (8 children with CP), 6-15 years old. Intense exercise had: 1) a significant, large, positive effect on reaction time (RT) for the CP group (pre-exercise: 892 ± 56.5 ms vs. post-exercise: 798 ± 45.6 ms, p<0.002, d=1.87) with a trend for a similar but smaller response for the typically developing (TD) group (pre-exercise: 855 ± 56.5 ms vs. post-exercise: 822 ± 45.6 ms, p<0.08, d=0.59), and 2) a significant, medium, negative effect on the interference effect for the CP group (pre-exercise: 4.5 ± 2.5 %RT vs. post-exercise: 13 ± 2.9 %RT, p<0.04, d=0.77) with no significant effect for the TD group (pre-exercise: 7.2 ± 2.5 %RT vs. post-exercise: 6.9 ± 2.9 %RT, p>0.4, d=0.03). Response accuracy was high in both groups pre- and post-exercise (>96%). In conclusion, intense exercise impacts cognitive functioning in children with CP, both by increasing processing speed and decreasing executive function.

    ABSTRACT: Near-infrared spectroscopy (NIRS) has long been used to measure tissue-specific O2 dynamics in exercise, but most published data have used continuous wave devices incapable of quantifying absolute Hemoglobin (Hb) concentrations. We used time-resolved NIRS (TR-NIRS) to study exercising muscle (Vastus Lateralis, VL) and prefrontal cortex (PFC) Hb oxygenation in 11 young males (15.3 ± 2.1 yrs) performing incremental cycling until exhaustion (peak VO2 = 42.7 ± 6.1 ml/min/kg, mean peak power = 181 ± 38 W). TR-NIRS measurements of reduced scattering (µs´) and absorption (µa) at three wavelengths (759, 796, and 833 nm) were used to calculate concentrations of oxyHb ([HbO2]), deoxy Hb ([HbR]), total Hb ([THb]), and O2 saturation (stO2). In PFC, significant increases were observed in both [HbO2] and [HbR] during intense exercise. PFC stO2% remained stable until 80% of total exercise time, then dropped (-2.95%, p = .0064). In VL, stO2% decreased until peak time (-6.8%, p = .01). Segmented linear regression identified thresholds for PFC [HbO2], [HbR], VL [THb]. There was a strong correlation between timing of second ventilatory threshold and decline in PFC [HbO2] (r = .84). These findings show that TR-NIRS can be used to study physiological threshold phenomena in children during maximal exercise, providing insight into tissue specific hemodynamics and metabolism.

    ABSTRACT: The aim of this study was to analyze the reliability and the validity of the handgrip, basketball throw and push-ups tests in children aged 6-12 years. One hundred and eighty healthy children (82 girls) agreed to participate in this study. All the upper body muscular fitness tests were performed twice (7 days apart) whereas the 1 repetition maximum (1RM) bench press test was performed 2 days after the first session of testing. All the tests showed a high reproducibility (ICC > 0.9) except the push-ups test (inter-trial difference = 0.77 ± 2.38, p < 0.001 and the percentage error = 9%). The handgrip test showed the highest association with 1RM bench press test (r = 0.79, p < 0.01; R2 = 0.621). In conclusion the handgrip and basketball throw tests are shown as reliable and valid tests to assess upper body muscular strength in children. More studies are needed to assess the validity and the reliability of the upper body muscular endurance tests in children.

    ABSTRACT: NIH Director Francis Collins noted that the Common Fund initiative would lead to unprecedented insights into the mechanisms responsible for the health effects of physical activity. He noted: "Armed with this knowledge, researchers and clinicians may one day be able to define optimal physical activity recommendations for people at various stages of life, as well as develop precisely targeted regimens for individuals with particular health needs." Given the ominous burden of physical inactivity-related diseases and conditions in otherwise healthy children, and the growing number of children who survive chronic diseases in whom we know little about what constitutes healthy exercise, it is essential that the community of child health researchers develop compelling strategies and proposals in response to the unique opportunity offered through the Common Fund mechanism.

    ABSTRACT: To examine the role of ventilatory constraint on cardiorespiratory fitness in obese adolescents. Thirty obese adolescents performed a maximal incremental cycling exercise and were divided into two groups based on maximal oxygen uptake (VO2peak): a group presenting low (L; n=15; VO2peak: 72.9±8.6 % predicted) or normal (N; n=15; VO2peak: 113.6±19.2% predicted) cardiorespiratory fitness. Both were compared with a group of healthy controls (C; n=20; VO2peak: 103.1±11.2% predicted). Ventilatory responses were explored using the flow-volume loop method. Cardiorespiratory fitness (VO2peak, in % predicted) was lower in L compared with C and N and was moderately associated with the % predicted forced vital capacity (FVC) (r=0.52; p<0.05) in L. At peak exercise, end inspiratory point was lower in L compared with N and C (77.4±8.1 , 86.4±7.7 and 89.9±7.6 % FVC in L, N and C respectively; p<0.05), suggesting in L an increased risk of ventilatory constraint although at peak exercise this difference could be attributed to the lower maximal ventilation in L. Forced vital capacity and ventilatory strategy to incremental exercise slightly differed between N and L. These results suggest a modest participation of ventilatory factors to exercise intolerance.

    ABSTRACT: FITNESSGRAM® criterion-referenced standards for aerobic capacity have been established to classify students according to their aerobic fitness status. The purpose of this study was to determine the association between waist circumference (WC) and FITNESSGRAM® aerobic capacity criterion-referenced standard classification. Subjects were 528 sixth-grade boys and girls who completed the FITNESSGRAM® test. Aerobic capacity was determined from one-mile run times. Logistic regression revealed that WC was significantly related to the odds of being classified as HFZ for both girls, p < .0001, and boys, p < .0001. The odds ratios indicated that an increase in WC by one centimeter would decrease the odds of being classified as HFZ by 28% in girls and 25% in boys. ROC analysis indicated that a WC of 68.6 cm for girls (AUC = .95) and 76.2 cm for boys (AUC = .97) represent the best thresholds for HFZ classification for aerobic capacity. These data demonstrate the strong association between WC and HFZ standard classification, and identify WC values that represent improved odds for HFZ classification for aerobic capacity. Such WC targets are important since children in the Needs Improvement (NI) category are more likely to develop health problems in adulthood.

    ABSTRACT: This study aims to 1) use the objective activPAL activity monitor to assess physical activity behaviours, including sitting/lying, standing and both light (LIPA) and moderate-to-vigorous physical activity (MVPA), 2) to develop distinct activity profiles based on time spent in each behaviour in a sample of adolescent females and 3) examine whether levels of adiposity differ across these activity profiles. Female adolescents (n=195; 14-18 years) had body mass index (median=21.7 (IQR=5.2) kg/m2) and 4-site skinfold thickness (median 62.0 mm; IQR=37.1) measured. Physical activity behaviours were measured using the activPAL. Hierarchical cluster analysis grouped participants into activity profiles based on similar physical activity characteristics. Linear mixed models explored differences in body composition across activity profiles. Three activity profiles were identified, a low (n=35), moderate (n=110) and a high activity profile (n=50). Significant differences across activity profiles were observed for skinfold thickness (p=0.046), with higher values observed in the low activity profile compared to the high activity profile. Profiling free-living activity using behaviours from across the activity intensity continuum may account for more of the variability in energy expenditure then examining specific activity intensities, such as MVPA alone. The use of activity profiles may enable the identification of individuals with unhealthy activity behaviours, leading to the development and implementation of more targeted interventions.

    ABSTRACT: To determine the acute effects of high-intensity intermittent exercise (HIIE) on vascular function. Lean (n=18, BMI=17.1±0.7) and obese (n=17, BMI=25.4±0.8) prepubescent boys aged 10.2±0.2 years were studied. HIIE consisted of 8 sets of 20 seconds of cycle ergometry at 100, 130, and 170% of VO2peak alternating with 10 seconds of rests. The obese group had higher (p<0.05) body mass, BMI, body fat percentage, waist-hip ratio than the lean group. Carotid artery wall thickness and arterial stiffness as assessed by brachial-ankle pulse wave velocity (baPWV) were greater in the obese than in the lean group (p<0.05). Brachial artery flow-mediated dilation (FMD) was not different between the groups. Total energy expenditure increased gradually as the exercise intensity increased in both groups (P<0.05). The obese group had significantly greater total energy expenditure in all three HIIE intensities than the lean group. FMD tended to be higher and baPWV lower as the exercise intensity increased in both groups. Only the HIIE at 170% demonstrated greater FMD compared with the baseline in both groups. baPWV decreased significantly after HIIE at 130 and 170% VO2peak in both groups. Supramaximal HIIE can be a feasible exercise modality for improving vascular function in obese prepubescent boys. Future exercise intervention studies are warranted.
