Mobile eye tracking technology enables the objective evaluation of what, when, and how athletes use visual information from the environment to control action in service of skilled performance. This review highlights the strengths, weaknesses, opportunities, and threats (SWOT) to consider before adopting this technology to evaluate visual–motor control for enhanced skill acquisition and performance in sport. Strengths include increased ecological validity by recording the athlete within their natural performance environment. Weaknesses include diminished tracking fidelity based on the eye’s morphology or squinting, eye tracker movement, and lens fogging. Opportunities consist of novel assessments around research themes such as combatting the negative effects of pressure and performance enhancement through personalized training. The formfitting technologies also introduce recording opportunities during standard practices. Data processing time, synchronization of video streams, and hand coding of variables comprise the threats in addition to the hardware cost and the fees associated with crowdsourcing data coding. Currently, it is also not feasible to provide coaches with a report of their athletes’ data in a timeline suitable to create player-specific drills. Evaluating portable eye tracking technology with a SWOT framework helps translate scientific knowledge to practitioners considering implementing this technology for athlete assessment and development.

Virtual Neuromuscular Training Among Physically Active Young Adults: A Feasibility Study
Samantha N. Magliato, Mathew J. Wingerson, Katherine L. Smulligan, Casey C. Little, Vipul Lugade, Julie C. Wilson, and David R. Howell
Context: Evidence indicates a 2 to 3 times increased risk of musculoskeletal injury after return to play from concussion. Undetected neuromuscular control deficits at return to play may relate to increased musculoskeletal injury risk. Rehabilitation to improve neuromuscular control may benefit patients with concussion, but access to rehabilitation professionals and/or poor adherence may limit efficacy. Our purpose was to determine the feasibility of an 8-week virtual neuromuscular training (NMT) program administered through a novel smartphone application among physically active, uninjured adults. Design: Feasibility trial. Methods: Participants were instructed to complete an NMT program administered via a smartphone application and returned for follow-up questionnaires 8 weeks later. They were instructed to complete 3 asynchronous self-guided workouts per week during the 8-week intervention period. Workouts included balance, plyometrics, strengthening, and dual-task exercises. The application provided instructions for each exercise using video, text, and audio descriptions. Our primary feasibility measure was participant adherence, calculated as the percentage of workouts completed out of the total possible 24 workouts. We recorded the average duration of each workout using start/stop/advance features within the application. Results: Twenty participants were enrolled, of which 15 (age = 26.3 [2.7] y, 67% female) returned for follow-up (75% retention). Participant adherence was 57.2% (25.0%; range: 16.7%–91.7%). Participants spent 17.3 (8.0) minutes per workout (range: 7.4–37.9 min). There were no adverse reactions or injuries. Most participants (60%) reported time availability as a primary barrier to intervention completion. Conclusions: Participants were moderately (>50%) adherent to a virtual NMT program, without any reported injuries. We identified several barriers to participation and pathways for improved adherence in the future. The virtual NMT program completed by uninjured adults provides evidence of its feasibility and future scalability to those with a recent concussion to address neuromuscular control deficits and reduce future injury risk.
Wii Fit Exercise’s Effects on Muscle Strength and Fear of Falling in Older Adults With Alzheimer Disease: A Randomized Controlled Trial
Fatma Uğur and Meral Sertel
Purpose: This study aimed to investigate how Wii Fit exercises affect muscle strength and fear of falling in older adults with Alzheimer’s disease. Method: The study included a total of 32 volunteers with Alzheimer’s disease, aged 65–80 years. These participants were divided into two groups: the exercise group and the control group. The exercise group received a 30-min (one session) twice-weekly exercise program for 6 weeks with games selected from different categories, such as balance and aerobic exercises, with the Nintendo Wii virtual reality device. During this period, the control group did not receive any treatment, and routine medical treatments continued. At baseline and 6 weeks later, Mini-Mental State Examination, knee extension muscle strength, Timed Up and Go Test, and Tinetti Fall Efficacy Scale results were recorded in the exercise and control groups. Results: In intragroup comparison, a statistically significant difference was found in all tests (muscle strength, Timed Up and Go Test, and Tinetti Fall Efficacy Scale) in the exercise group after the exercise program (p < .05), while no significant difference was found in the control group (p > .05). According to the interaction of group and time in the intergroup comparison, there was no difference between the groups (exercise and control group) in muscle strength and Timed Up and Go Test (p > .05), but there was a difference in Tinetti Fall Efficacy Scale (p < .05). Conclusions: This randomized controlled trial supports the claim that Wii Fit exercises can reduce the fear of falling in older adults with Alzheimer’s disease.

Administering Internships in Sport Management: Comparing Practices in the Discipline
Michael A. Odio, Cassandra J. Coble, and Emily Padgett Plunkett
This study examined how academic programs administrate their internships, including implementing and executing their philosophy and internship rationale, and connecting with and managing relationships with internship agencies while accounting for contextual information (e.g., geography, size, and research vs. teaching focus). Using a case-study methodology, 12 sport management programs’ internship approaches were analyzed, leading to several cross-case themes and larger interpretations useful for advancing future research and practice related to internships. Several commonalities and differences were observed that offer insight important for interpreting existing research and recommending practices across programs.
Countermovement Jump and Isometric Strength Test–Retest Reliability in English Premier League Academy Football Players
Matthew Springham, Nav Singh, Perry Stewart, Jordan Matthews, Ian Jones, Charlie Norton-Sherwood, Dominic May, Jamie Salter, Anthony J. Strudwick, and Joseph W. Shaw
Purpose: To examine the test–retest reliability of countermovement jump (CMJ) and isometric strength testing measures in elite-level under-18 and under-23 academy football players. Methods: A total of 36 players performed 3 maximal CMJs and isometric abductor (IABS), adductor (IADS), and posterior chain (IPCS) strength tests on 2 separate test days using dual force plates (CMJ and IPCS) and a portable strength testing device (IABS and IADS). Relative (intraclass correlation coefficient) and absolute (coefficient of variation, standard error of the measurement, and minimal detectable change [MDC%]) reliabilities for 34 CMJ, 10 IABS, 10 IADS, and 11 IPCS measures were analyzed using between-sessions best, mean, and within-session methods. Results: For all methods, relative reliability was good to excellent for all CMJ and all IADS measures and poor to good for all IABS and IPCS measures. Absolute reliability was good (ie, coefficient of variation < 10%) for 27 (best) and 28 (mean) CMJ variables and for 6 (IABS and IADS) and 2 (IPCS) isometric measures. Commonly used CMJ measures (jump height, eccentric duration, and flight-time:contraction-time ratio) had good to excellent relative reliability and an MDC% range of 14.6% to 23.7%. Likewise, commonly used isometric peak force measures for IABS, IADS, and IPCS had good to excellent relative reliability and an MDC% range of 22.2% to 26.4%. Conclusions: Commonly used CMJ and isometric strength measures had good test–retest reliability but might be limited by their MDC%. Rate-of-force-development measures (for all isometric tests) and impulse measures (IPCS) are limited by poor relative and absolute reliability and high MDC%. MDC% statistics should be considered in the context of typical responsiveness.
Does He Make a Difference? Analyzing the Role of Men Athletes in the Framing of Elite Women CrossFit Athletes in Sportswear Retailers’ Marketing Materials
Alexandra Gibson and Andrea N. Geurin
This study examined the role of men athletes in framing women athletes in marketing images, and CrossFit was used as the sport-specific context. The purpose was to understand how consumers perceive women athletes, whether the presence of men athletes influences these perceptions, and if consumers perceive women athletes to be represented more accurately when pictured alone or with male counterparts. Using a mixed-methods approach involving both quantitative and qualitative analysis, questionnaires (n = 389) and interviews (n = 19) were utilized to gather participants’ perceptions on videos featuring all women CrossFit athletes and/or those with men and women CrossFit athletes. Results showed that consumers’ perceptions began to shift when looking at their athletic competence, although a focus on appearance remained. While the results of the questionnaires revealed no clear correlation between the presence of men athletes and the perception of women athletes, the interviews suggested a relationship, highlighting the complex role that male athletes play. Overall, the study indicates that consumers perceive women athletes to be framed more accurately when pictured alone and offers valuable insights into how men athletes affect consumers’ perceptions of women athletes.
