Does Athlete Status Explain Sexual Violence Victimization and Perpetration on College Campuses? A Socio-Ecological Study.

In the United States, college students have been identified as a high-risk group for sexual violence (SV) victimization and perpetration, with one in three women and one in four men experiencing SV in their lifetimes. Therefore, studies investigating both perpetration and victimization across genders are pertinent. Additionally, in the context of higher education, athletics is often viewed as a high-risk environment for SV. Despite established relationships between SV and intercollegiate athletics, research on this topic is not conclusive due to the heterogeneous nature of college sports, as well as a dearth of research on recreational athletes. The primary purpose of this study was to examine the differences in SV victimization and perpetration among intercollegiate, recreational, and non-athlete populations. Additional context was provided by exploring variables at multiple levels of the socio-ecological model for violence prevention, as these factors can be important aspects of a person's development and may inform behavior. Utilizing a sample of 62,996 students from 199 institutions of higher education in the United States, multilevel logistic regression analyses were conducted to assess individual- (i.e., personal demographics), relationship- (i.e., athlete status), and community-level (i.e., institutional characteristics) predictors of SV victimization and perpetration. The results indicated that recreational athletes are the most at-risk group, experiencing and perpetrating SV at higher rates than non-athletes. Results on institutional status and individual characteristics, as well as implications for practitioners and future research is discussed.

A Pilot Study on Cannabidiol (CBD) and Eccentric Exercise: Impact on Inflammation, Performance, and Pain.

Cannabidiol (CBD) is a non-psychoactive cannabinoid purported to reduce symptoms of discomfort. Individuals are now using CBD to treat symptoms of multiple sclerosis, seizures, and chronic pain. Animal models indicate that CBD may be effective at reducing inflammation post fatiguing exercise. However, little evidence is available to evaluate these findings in humans. Therefore, the purpose of this investigation was to evaluate the impact of two doses of CBD oil on inflammation (IL-6), performance, and pain after an eccentric loading protocol. Participants (n = 4) participated in three conditions (placebo, low dose, and high dose), in this randomized, counterbalanced design. Each condition took 72 hours to complete, with a 1-week washout period between conditions. At the beginning of each week, participants were subjected to a loading protocol of six sets of ten eccentric only repetitions in the single-arm bicep curl. Participants consumed capsules of either a placebo, low dose (2mg/kg) or high dose (10mg/kg) of CBD oil immediately following the session and continued every twelve hours for 48 hours. Venipunctures were taken before exercise and repeated at 24, 48, and 72 hours post exercise. Blood samples were centrifuged for 15 minutes in gel and lithium heparin vacutainers. Plasma was separated from cells and stored at -80° until analysis. Samples were analyzed using an immunometric assay for IL-6 (ELISA). Data were analyzed using a three (condition) by four (time) repeated measure ANOVA. There were no differences in inflammation between conditions (F(2,6) = 0.726, p = 0.522, np 2 = 0.195) or across time (F(3,9) = 0.752, p = 0.548, np 2 = 0.200), handgrip strength between conditions (F(2,6) = 0.542, p = 0.607, np 2 = .153) or across time (F(3,9) = 2.235, p = .153, np 2 = .427), or bicep curl strength between conditions (F(2,6) = 0.675, p = 0.554, np 2 = .184) or across time (F(3,9) = 3.513, p = .150, np 2 = .539). There were no differences in pain between conditions (F(2,6) = 0.495, p = 0.633, np 2 = .142), but there was a difference across time (F(3,9) = 7.028, p = .010, np 2 = .701). There were no significant interactions to note. Although there was no statistical significance between conditions (likely due to the low sample size), there was a visible increase in IL-6 48 (4.88 ± 6.53) and 72 hours (3.12 ± 4.26) post exercise in the placebo condition which was not observed in the low (48: 0.35 ± 2.22; 72: 1.34 ± 5.6) and high dose condition (48: 1.34 ± 1.34; 72: -0.79 ± 5.34). Future investigations should consider implementing eccentric resistance training across a larger portion of the body to improve ecological validity of the exercise. A larger sample would reduce risk of researchers committing a type II statistical error and give strength to detecting differences between conditions.

Investigating the Social Network Structure of Physical Literacy Scholars to Advance a Paradigm for Physical Activity Promotion.

Purpose: Physical literacy has quickly gained global attention as a holistic approach to combat physical inactivity and obesity. However, research silos may limit the growth and application of the physical literacy paradigm for effective physical activity promotion. The purpose of this study was to measure the underlying network structure of scholars publishing on physical literacy (focusing on empirical research) through co-authorship analysis. Methods: Data collection resulted in 1,070 documents related to physical literacy retrieved. A total of 198 articles met inclusion criteria and were included in the full network, with authors operationalized as actors in the network. A total of 75 empirical studies were included in the sub-network for critical appraisal and further analysis. Social network analysis was then conducted at the macro- and component-level, using quantification and visualization techniques. Results: Results revealed a collaborative, yet fragmented physical literacy network with sub-groups representing substantive and geographically diverse scholars. The majority of scholarship lacked empirical evidence, suggesting a research-practice gap. Conclusion: Recommendations for advancing physical literacy research and practice include strategic collaborations that transcend geographic and disciplinary boundaries, cooperative efforts across scholars and practitioners, and productive discourse through professional avenues to progress knowledge generation, dispersion, and application.
