Purpose: Youth sport has the potential to be one of the healthiest and most beneficial activities in which children can partake. Participation in a combination of adult-led and peer-led sport structures appears to lead to favorable outcomes such as enhanced physical fitness, as well as social and emotional development. The purpose of the present study was to examine the subjective and objective experiences of 27 recreational male soccer players aged 10 to 12 years old (M = 10.11 years, SD = 0.32) across adult-led and peer-led sport structures. Method: Direct video observation and experience-rating scales were utilized in an effort to shed light on the impact of adult-led and peer-led sport structures on the same athletes. Results: In the adult-led structures, youth experienced high levels of effort and concentration while spending more time physically or mentally engaged. Meanwhile, youth experienced high rates of prosocial behaviors, sport-related communication, and general communication during the peer-led structures. Conclusions: The results of the present study indicate that rather than one approach being superior to the other, both adult- and peer-led sport structures have the potential to yield unique benefits toward children's positive experiences in sport.
