The present study sought to address 2 limitations of previous athlete-leadership research: (a) Researchers have predominantly examined the shared nature of athlete leadership using aggregated approaches, which has limited our ability to examine differences in the degree of sharedness between teams, and (b) the limited availability of research related to dyadic predictors (i.e., qualities of the relation between 2 individuals) of athlete leadership. Therefore, social-network analysis was used to examine athlete leadership across multiple levels (i.e., individual, dyadic, and network) in 4 competitive female youth soccer teams (N = 68). Findings demonstrated differences in the degree to which athlete leadership was shared between the teams. Furthermore, multiple-regression quadratic-assignment procedures showed that skill nomination and formal leadership status were significant predictors of how often participants reported looking to their teammates for leadership.

The purpose of our study was to examine exercise dependence (EXD) in a large community-based sample of runners. The secondary purpose of this study was to examine differences in EXD symptoms between primary and secondary EXD. Our sample included 2660 runners recruited from a local road race (M age = 38.78 years, SD = 10.80; 66.39% women; 91.62% Caucasian) who completed all study measures online within 3 weeks of the race. In this study, EXD prevalence was lower than most previously reported rates (gamma = .248, p < .001) and individuals in the at-risk for EXD category participated in longer distance races, F(8,1) = 14.13, p = .01, partial eta squared = .05. Group differences were found for gender, F(1,1921) 8.08, p = .01, partial eta squared = .004, and primary or secondary group status, F(1,1921) 159.53, p = .01, partial eta squared = .077. Implications of primary and secondary EXD differences and future research are discussed.
