Mediator Variable

Abstract Transcriptomics, regional cerebral blood flow (rCBF), and a virtual reality-based spatial motor task were integrated using mediation analysis in a novel demonstration of “imaging omics.” Data collected in National Collegiate Athletic Association (NCAA) Division I football athletes cleared for play before in-season training showed significant relationships in 1) elevated levels of miR-30d and miR-92a to elevated putamen rCBF, 2) elevated putamen rCBF to compromised Balance scores, and 3) compromised Balance scores to elevated microRNA (miRNA) levels. rCBF acted as a consistent mediator variable (Sobel’s test P < 0.05) between abnormal miRNA levels and compromised Balance scores. Given the involvement of these miRNAs in inflammation and immune function and that vascular perfusion is a component of the inflammatory response, these findings support a chronic inflammatory model in these athletes with 11 years of average football exposure. rCBF, a systems biology measure, was necessary for miRNA to affect behavior.

The 1984 Supreme Court ruling in the antitrust suit between the Universities of Oklahoma and Georgia, representing the College Football Association (CFA), versus the National Collegiate Athletic Association (NCAA) provided mat individual institutions had proper authority to sell television rights to their football games. The NCAA had controlled television appearances of collegiate football teams with the rationale of preventing erosion of game attendance due to televised home football games. Records of home games televised, television revenues from football games, and attendance at televised football games were gathered from 57% of NCAA Division I institutions and compared for a 3-year period prior to the 1984 ruling, with a 3-year period following the ruling. Four sets oft tests between mean data for the pre- and posttime periods showed that although the number of games scheduled per season remained the same, the number of televised football games significantly increased, the television revenues from football remained constant, and attendance at televised home football games decreased significantly after the 1984 ruling.

One hundred twenty university counseling centers and athletic-department websites were viewed and analyzed for the provision of sport psychology services specifically to NCAA (National Collegiate Athletic Association) Division I Football Bowl Championship Series (FBS) student athletes. Using content-analysis methodology, the present research identified a fair number of university athletic departments (n = 29) and university counseling centers (n = 6) that provided specific sport psychology services. In addition, most athletic departments and counseling centers that provided sport psychology services had one individual on staff who was listed as the service provider. Results of the study are discussed in relation to providing a current understanding of the extent to which sport psychology is presently being provided to NCAA Division I FBS university student athletes. Future qualitative research is recommended to examine the work of professionals providing sport psychology services in athletic departments and counseling centers to better understand the precise nature of the services provided.

Purpose: The purpose of this study was to examine core temperature (TC) and markers of dehydration during one-a-day (D1) practices compared to two-a-day (D2) practices. Methods: Twenty-five National Collegiate Athletic Association (NCAA) Division I Football Championship Subdivision (FCS) football players volunteered to participate in the study, with thirteen subjects providing data for all four practices. Each subject was measured prior to and following D1 and D2 practices and tested for body mass, core temperature, supine and standing blood pressure, and blood volume changes. Environmental temperature, humidity and barometric pressure were measured at the practice field during the last hour of each practice. Results: During moderate environmental temperatures and humidity, body mass was found to decrease following practice. Core temperature increased following both types of practice. Post practice plasma volume was 4% higher following D1 compared to D2 practice type. Conclusions/Recommendations: In this study, these NCAA Division I FCS football players remained well-hydrated during preseason practice training. The athletes’ plasma volume increased during practice, and even though core temperature increased, it remained lower than levels at which heat illness is indicated. In conclusion, the results of this study indicate that the risk of heat illness in NCAA Division I FCS football players is very low during fall football training practices in conditions of moderate heat and humidity. We recommend that this study should be repeated in various environments, including higher temperatures and/or percent relative humidity where the risk of heat illness may be greater.

The Relationship

The estimated one-repetition maximum (1RM) bench press and NFL-225 (225-lb or 102-kg) repetition test are commonly used to assess upper-body muscular strength and endurance among football players. However, little research has been focused on the relationship of these tests to playing status. Therefore, the purpose of this study was to determine if significant relationships exist between these tests and playing status in Division I football athletes. Archival data from 31 NCAA Division I football players (age: 20.1±1.4 yrs., height: 188.07 ± 5.93 cm, body mass: 112.4 ± 19.5 kg) on the 1RM Bench press test, NFL-225 test and playing status were utilized for this analysis. A one-way ANOVA was used to detect any differences in 1RM and NFL-225 performance between skill groups: big (linemen), medium (linebackers, quarterbacks, tight ends) and small (receivers, backs, and corners) (p < 0.05). Playing status (starters vs. non-starters) were compared within position groups. A point bi-serial correlation was then utilized to examine the relationship in test performance between groups, as well as between starters and non-starters. Significant differences were discovered in NFL-225 test performance between big and small skill groups. Moderate-to-strong relationships between playing status and performance on the 1RM bench press (r = .660) and the NFL-225 test (r = .685) for the big skills group. The results of this study suggest that playing status and upper-body strength and endurance are strongly related for the big skills position group.

The Federal Bureau of Investigation (“FBI”) and U.S. Attorney’s Office’s investigation into National Collegiate Athletic Association (“NCAA”) Division I men’s basketball revealed allegations of NCAA Division I men’s basketball coaches accepting money from sport agents to persuade NCAA Division I men’s basketball players to become clients of said sport agents. This investigation highlights the pervasiveness of violations of preexisting laws governing sport agents, namely, the Uniform Athlete Agents Act (the “UAAA”) and Sport Agent Responsibility and Trust Act (“SPARTA”). Despite the believed routine violation of the UAAA and SPARTA in the recruitment of NCAA student-athletes as clients by sport agents, the laws are rarely used to prosecute sport agents. Thus, the investigation into NCAA Division I men’s basketball highlights the need for new mechanisms to safeguard the rights and interests of NCAA student-athletes related to sport agents. This paper analyzes the efficacy of existing legal and NCAA mechanisms regulating sport agents and presents a thematic analysis of NCAA Division I Football Bowl Subdivision (“FBS”) member institutions’ sport agent policies to highlight the need for and present a model NCAA Division I FBS member institution sport agent policy and education model.

The purpose of this longitudinal, descriptive study was to observe changes in maximal strength measured via isometric clean grip mid-thigh pull and home runs (total and home runs per game) across three years of training and three competitive seasons for four National Collegiate Athletic Association (NCAA) Division 1 baseball players. A one-way repeated measures analysis of variance (ANOVA) was performed, revealing significant univariate effects of time for peak force (PF) (p = 0.003) and peak force allometrically scaled (PFa) (p = 0.002). Increases in PF were noted from season 1 to season 2 (p = 0.031) and season 3 (p = 0.004), but season 2 was not significantly different than season 3 (p = 0.232). Additionally, increases in PFa were noted from season 1 to season 2 (p = 0.010) and season 3 (p < 0.001), but season 2 was not significantly different than season 3 (p = 0.052). Home runs per game rose from the 2009 (0.32) to 2010 season (1.35) and dropped during the 2011 season (1.07). A unique aspect of the study involves 2010 being the season in which ball-bat coefficient of restitution (BBCOR) bats were introduced to the NCAA competition.

Background: Achilles tendon (AT) ruptures are devastating injuries that are highly prevalent among athletes. Despite our understanding of the effect of AT rupture and in particular its relationship to basketball, no study has examined the effects of AT rupture and repair on performance metrics in collegiate basketball players. Purpose: To evaluate the effect of AT rupture and subsequent surgical repair on performance metrics in National Collegiate Athletic Association (NCAA) Division I basketball players who return to play after injury. Study Design: Descriptive epidemiology study. Methods: NCAA Division I basketball players who sustained an AT rupture and underwent subsequent surgical repair between 2000 and 2019 were identified by systematically evaluating individual injury reports from databases comprising NCAA career statistics and individual school statistics; 65 male and 41 female players were identified. Athletes were included if they participated in at least one-half of the games of 1 collegiate season before tearing the AT and at least 1 season after operative repair. A total of 50 male and 30 female athletes were included. Each injured athlete was matched to a healthy control by conference, position, starter status at time of injury, class year, and number of games played. Matched controls were healthy players and experienced no significant injuries during their NCAA careers. Results: After AT repair, male athletes had significantly more minutes per game, points per game, and compared with before injury. Total blocks significantly decreased after injury. Female athletes scored significantly more points per game but demonstrated a significantly lower 3-point shooting percentage after return to play. Despite undergoing AT rupture and repair, 14% of male players played in the National Basketball Association, and 20% of injured female athletes played in the Women’s National Basketball Association. Conclusion: After returning to play, men demonstrated a significant drop-off in performance only in regard to total blocks. Female athletes after AT repair demonstrated a significant improvement in points per game but had a significant drop-off in 3-point shooting percentage.

Context:  Female athletic trainers (ATs) can face barriers to employment within the profession. Although there is evidence for an increasing percentage of women in athletic training, the portion providing medical care to male sport teams within the professional sport and collegiate settings continues to be small. Objective:  To investigate the experiences of female ATs when seeking employment with male sport teams within the Division I setting. Design:  Qualitative study. Setting:  National Collegiate Athletic Association (NCAA) Division I. Patients or Other Participants:  A total of 15 NCAA Division I female ATs providing medical care to a male sport team participated in our study. Their mean age was 33 ± 9 years, and they had a mean of 11 ± 9 years of overall clinical experience. Data Collection and Analysis:  All participants completed one-on-one phone interviews, which were recorded and transcribed. Analysis of the data followed thematic analysis using a phenomenologic approach. Credibility was established through credibility checks, peer review, and researcher triangulation. Results:  Factors that played a role in women gaining employment with male sport teams were (1) preexisting professional relationships, (2) prior experience with a male sport, and (3) perseverance. Participants in our study were most attracted to their current positions because of (1) the environment of the collegiate setting and (2) the location of the university. Conclusions:  Job access for female ATs in this study was not viewed as a challenge. Familiarity through previous connections with the university and staff and commitment to career goals helped these women obtain the positions they held. The desire to work in male sports was not a primary contributing factor to the decision-making process. Progress continues for women in athletic training, as evidenced by the reported ease of job access with male sport teams.

For the past several decades, machine learning has played an important role in sports science with regard to player performance and result prediction. However, it is still challenging to quantify team-level game performance because there is no strong ground truth. Thus, a team cannot receive feedback in a standardized way. The aim of this study was twofold. First, we designed a metric called LAX-Score to quantify a collegiate lacrosse team's athletic performance. Next, we explored the relationship between our proposed metric and practice sensing features for performance enhancement. To derive the metric, we utilized feature selection and weighted regression. Then, the proposed metric was statistically validated on over 700 games from the last three seasons of NCAA Division I women's lacrosse. We also explored our biometric sensing dataset obtained from a collegiate team's athletes over the course of a season. We then identified the practice features that are most correlated with high-performance games. Our results indicate that LAX-Score provides insight into athletic performance beyond wins and losses. Moreover, though COVID-19 has stalled implementation, the collegiate team studied applied our feature outcomes to their practices, and the initial results look promising with regard to better performance.
