Stroiney, DA, Mokris, RL, Hanna, GR, and Ranney, JD. Examination of self-myofascial release vs. instrument-assisted soft-tissue mobilization techniques on vertical and horizontal power in recreational athletes. J Strength Cond Res XX(X): 000-000, 2018-This study examined whether pre-exercise self-myofascial release (SMR) and instrument-assisted soft-tissue mobilization (IASTM) would improve performance on measures of vertical jump height and 40-yd sprint time. Differences in perceived pain levels were also examined. Forty-nine college students volunteered for the study and were randomly assigned to receive either IASTM via Tècnica Gavilàn PTB or SMR via The Stick before performance assessments. After the massage intervention, subjects rated their level of perceived pain using a visual analog scale. An independent t test was used to analyze differences in perceived pain levels between the 2 massage interventions. A 2 × 2 analyses of covariance analyzed differences between sex and the 2 massage interventions. There was no interaction (p > 0.05) between the massage intervention and sex for both the vertical jump and 40-yd sprint tests. There was a significant main effect for vertical jump and SMR (p = 0.04). Sex also had a significant main effect for both the vertical jump (p = 0.04) and the 40-yd sprint (p = 0.02). There were no significant differences between massage interventions for the 40-yd sprint times (p = 0.73). There were no significant differences in perceived pain (t(49) = -1.60, p > 0.05). The use of SMR before exercise may improve vertical jump height in recreational athletes. Pain should not be a factor when choosing massage interventions for athletes because IASTM was not perceived to be more painful than SMR. Self-myofascial release and IASTM did not enhance sprinting performance in this study.

Purpose: To examine faculty and academic support staff members' awareness and knowledge regarding concussions. Design: Cross-sectional, web-based questionnaire. Setting: Division II collegiate setting.

Purpose: To raise awareness of glucose-6-phosphate dehydrogenase (G6PD) deficiency, a disorder that causes anemic hemolysis, in young athletes.Methods: Data collection via interview, research analysis, and clinical application.Results: An 18-year-old male high school basketball player experienced recurring symptoms of fatigue, dizziness, and syncope during times of oxidative stress. Testing resulted in a diagnosis of G6PDD deficiency. Conclusions:With accurate diagnosis, individuals with G6PDD may participate in activity with modifications.
