Validity and Reliability of the Tampa Scale for Kinesiophobia for Adolescents with Heart Disease.

Kinesiophobia (KP) is the fear of movement or physical activity (PA) that is related to a medical condition. In adolescents, KP is associated with depression, anxiety, and impaired quality of life (QoL). Adolescents with heart disease (HD) often avoid PA.

Peak Oxygen Consumption (V̇O 2peak ) Recovery Delay in a Pediatric Fontan Population.

Purpose: The purpose of this study is to identify predictors and correlates of VO2RD in youth with Fontan.

Methods: Cardiopulmonary exercise test data was used from a single center, cross-sectional study of children and adolescents (age, 8-21 yr) with Fontan physiology. The VO2RD was determined using time (s) to <90% of V̇O 2peak and categorized as "low" (≤10 s) or "high" (≥10 s).

Moderators of peak respiratory exchange ratio during exercise testing in children and adolescents with Fontan physiology.

Objectives: Many patients with Fontan physiology are unable to achieve the minimum criteria for peak effort during cardiopulmonary exercise testing. The purpose of this study is to determine the influence of physical activity and other clinical predictors related to achieving peak exercise criteria, signified by respiratory exchange ratio ≥ 1.1 in youth with Fontan physiology.

Practices and Procedures in Clinical Pediatric Exercise Laboratories in North America.

Unlabelled: Interinstitutional differences in clinical pediatric exercise laboratory (CPEL) practices may affect patient care and efficacy of multicenter research.

Purpose: To describe current practices/procedures in CPELs and explore differences in CPELs employing exercise physiologists to those that do not.

Methods: A 40-item survey was distributed to CPELs in North America focusing on (1) staffing; (2) exercise stress testing (EST) volumes, reporting, and interpretation; and (3) EST procedures/protocols.

Heart Rate Recovery Following Exercise Testing in Pediatric Patients with Acyanotic Repaired Congenital Heart Disease.

Attenuated heart rate recovery (HRR) following peak exercise has been shown to be a predictor of mortality in populations of adults with Fontan palliation, coronary artery disease, heart failure, and heart transplantation. However, few have studied HRR in children and adolescents with congenital heart disease (CHD). This case-control study compared HRR patterns from exercise stress testing in children and adolescents with and without repaired acyanotic CHD (raCHD).

Physical Activity Patterns in Children and Adolescents With Heart Disease.

Purpose: To quantify the differences in daily physical activity (PA) patterns, intensity-specific volumes, and PA bouts in youth with and without heart disease (HD).

Methods: Seven-day PA was measured on children/adolescents with HD (n = 34; median age 12.4 y; 61.

Childhood Pulmonary Function, Exercise Capacity, and Exhaled Nitric Oxide Levels: Outcomes following Neonatal Treatment with Inhaled Nitric Oxide to Prevent Bronchopulmonary Dysplasia.

Objective: The goal was to determine if inhaled nitric oxide (iNO) for 3 weeks during neonatal care of high-risk preterm infants was associated with improved pulmonary function and exercise capacity or altered exhaled nitric oxide (FeNO) levels in later childhood.

Study Design: Thirty-four very preterm children previously enrolled in a randomized, neonatal trial of iNO to prevent chronic lung disease, were assessed in follow-up at 7 to 9 years of age, including pulmonary function testing (PFT), exercise testing, and measurement of FeNO.

Results: There were no differences in PFTs or exercise capacity between iNO treated and controls.

Effects of an acute bout of resistance exercise on fiber-type specific to GLUT4 and IGF-1R expression.

The effects of resistance exercise on fiber-type-specific expression of insulin-like growth factor I receptor (IGF-1R) and glucose transporter 4 (GLUT4) was determined in 6 healthy males. The expression of both genes increased in Type I fibers (p < 0.05), but only GLUT4 increased (p < 0.
