Item Effect of head impacts on diffusivity measures in a cohort of collegiate contact sport athletes(American Academy of Neurology, 2014-01-07) McAllister, Thomas W.; Ford, James C.; Flashman, Laura A.; Maerlender, Arthur; Greenwald, Richard M.; Beckwith, Jonathan G.; Bolander, Richard P.; Tosteson, Tor D.; Turco, John H.; Raman, Rema; Jain, Sonia; Department of Psychiatry, IU School of MedicineOBJECTIVE: To determine whether exposure to repetitive head impacts over a single season affects white matter diffusion measures in collegiate contact sport athletes. METHODS: A prospective cohort study at a Division I NCAA athletic program of 80 nonconcussed varsity football and ice hockey players who wore instrumented helmets that recorded the acceleration-time history of the head following impact, and 79 non-contact sport athletes. Assessment occurred preseason and shortly after the season with diffusion tensor imaging and neurocognitive measures. RESULTS: There was a significant (p = 0.011) athlete-group difference for mean diffusivity (MD) in the corpus callosum. Postseason fractional anisotropy (FA) differed (p = 0.001) in the amygdala (0.238 vs 0.233). Measures of head impact exposure correlated with white matter diffusivity measures in several brain regions, including the corpus callosum, amygdala, cerebellar white matter, hippocampus, and thalamus. The magnitude of change in corpus callosum MD postseason was associated with poorer performance on a measure of verbal learning and memory. CONCLUSION: This study suggests a relationship between head impact exposure, white matter diffusion measures, and cognition over the course of a single season, even in the absence of diagnosed concussion, in a cohort of college athletes. Further work is needed to assess whether such effects are short term or persistent.Item Exploring sport motivation and multi-dimensional wellness in NCAA Division II student-athletes(2017-11-17) Mayol, Mindy M.; Arnold, Brent L.; Koceja, David M.; Raglin, John S.; Staten, Lisa K.Too few studies relating to motivation and wellness have targeted the NCAA Division II student-athlete (SA) population. PURPOSES: To examine differences in SAs’ sport motivation (SM) types over three time points as well as multi-dimensional wellness (MDW) levels in SAs during one time point. METHODS: Overall, 530 Division II SAs (nmales = 355, nfemales = 175) with an overall age range of 18 to 23 (M = 19.40, SD = 1.33) from 21 teams voluntarily completed the 18-item Self-Determination Theory-based SM Scale II used to measure six motivation types, the 45-item MDW Inventory used to measure nine wellness dimensions, and a demographics questionnaire. Repeated measures Analyses of Variance (ANOVA) and 2x2x3 Mixed ANOVAs were used to analyze SM types while a multivariate ANOVA was used to analyze MDW with an alpha level of 0.05 set for statistical significance. RESULTS: Analyses demonstrated statistically significant differences in SM types over time (p = .05), interactions and differences in SM types between interactive/coactive and male/female SAs (p = .05), and interactions and differences in MDW levels between male/female SAs and SAs who completed/did not complete a college wellness course (p = .05). CONCLUSIONS: Findings suggested that autonomous-based SM types decreased over time whereas amotivation increased over time indicating possible athlete burnout. Interactive and female SAs showed similarities also representative of athlete burnout. SAs who completed the MDW course demonstrated higher physical wellness exercise scores than SAs who did not. Female SAs had higher means in five wellness dimensions when compared to male SAs. SAs who completed the course showed higher means for seven wellness dimensions versus SAs who did not. Further research should ensue to better understand motivation and wellness on a national scale examining Division I, II and III and NAIA athletes in order to provide more generalizable results.
