Abstract
The objective of this study was to examine the effect of a peer modeling intervention on
cardiorespiratory fitness performance and task self-efficacy in obese youth completing a maximal incremental treadmill test. Forty-nine obese youth (male = 26, BMI > 95th percentile for age and gender; 10 to 17 years of age) were randomized to an experimental group (n = 25) which received a peer modeling intervention or to an attention control group. The outcome variables were physical fitness (peak VO2, heart rate, duration, respiratory exchange ratio, rating of perceived exertion) and task self-efficacy. Observing the peer modeling intervention was not associated with improvements in peak V 0 2 or self-efficacy from baseline to follow-up in the experimental group; however, physical fitness and task self-efficacy were moderately correlated at both time points. The peer modeling intervention was partially successful at reducing variability in the experimental group, but not the control group.
