The effect of an integrated perceived competence and motor intervention in children with developmental coordination disorder.

Background And Aims: Children with DCD have lower self-perceptions and are less physically active than typically developing children. The aim of this quasi-experimental study was to investigate whether an integrated perceived competence and motor intervention affects DCD children's motor performance, self-perceptions, and physical activity compared with a motor intervention only.

Methods And Procedures: The intervention group consisted of 20 children and the care-as-usual group consisted of 11 children, all aged 7-10 years.

The change in perceived motor competence and motor task values during elementary school: A longitudinal cohort study.

Participation in motor activities is essential for social interaction and life satisfaction in children. Self-perceptions and task values have a central position in why children do or do not participate in (motor) activities. Investigating developmental changes in motor self-perceptions and motor task values in elementary school children would provide vital information about their participation in motor activities.

Exercise oxidative skeletal muscle metabolism in adolescents with cystic fibrosis.

What is the central question of this study? Do intrinsic abnormalities in oxygenation and/or muscle oxidative metabolism contribute to exercise intolerance in adolescents with mild cystic fibrosis? What is the main finding and its importance? This study found no evidence that in adolescents with mild cystic fibrosis in a stable clinical state intrinsic abnormalities in skeletal muscle oxidative metabolism seem to play a clinical significant role. Based on these results, we concluded that there is no metabolic constraint to benefit from exercise training. Patients with cystic fibrosis (CF) are reported to have limited exercise capacity.

Estimating peak oxygen uptake in adolescents with cystic fibrosis.

Objectives: To predict peak oxygen uptake (VO2 peak) from the peak work rate (W peak) obtained during a cycle ergometry test using the Godfrey protocol in adolescents with cystic fibrosis (CF), and assess the accuracy of the model for prognostication clustering.

Methods: Out of our database of anthropometric, spirometric and maximal exercise data from adolescents with CF (N=363; 140 girls and 223 boys; age 14.77 ± 1.

The Steep Ramp Test in Dutch white children and adolescents: age- and sex-related normative values.

Background: The Steep Ramp Test (SRT), a feasible, reliable, and valid exercise test on a cycle ergometer, may be more appealing for use in children in daily clinical practice than the traditional cardiopulmonary exercise test because of its short duration, its resemblance to children's daily activity patterns, and the fact that it does not require respiratory gas analysis.

Objective: The aim of the present study was to provide sex- and age-related normative values for SRT performance in Dutch white children and adolescents who were healthy and 8 to 19 years old.

Design: This was a cross-sectional, observational study.
