Additional Information

There is scarce research into the use of Strive Sense3 smart compression shorts to measure external load with accelerometry and muscle load (i.e., muscle activations) with surface electromyography in basketball. Sixteen external load and muscle load variables were measured from 15 National Collegiate Athletic Association Division I men’s basketball players with 1137 session records. The data were analyzed for player positions of Centers (n = 4), Forwards (n = 4), and Guards (n = 7). Nonparametric bootstrapping was used to find significant differences between training and game sessions. Significant differences were found in all variables except Number of Jumps and all muscle load variables for Guards, and all variables except Muscle Load for Forwards. For Centers, the Average Speed, Average Max Speed, and Total Hamstring, Glute, Left, and Right Muscle variables were significantly different (p < 0.05). Principal component analysis was conducted on the external load variables. Most of the variance was explained within two principal components (70.4% in the worst case). Variable loadings of principal components for each position were similar during training but differed during games, especially for the Forward position. Measuring muscle activation provides additional information in which the demands of each playing position can be differentiated during training and competition.

Purpose: To characterize the weekly training load (TL) and well-being of college basketball players during the in-season phase. Methods: Ten (6 guards and 4 forwards) male basketball players (age 20.9 [0.9] y, stature 195.0 [8.2] cm, and body mass 91.3 [11.3] kg) from the same Division I National Collegiate Athletic Association team were recruited to participate in this study. Individualized training and game loads were assessed using the session rating of perceived exertion at the end of each training and game session, and well-being status was collected before each session. Weekly changes (%) in TL, acute-to-chronic workload ratio, and well-being were determined. Differences in TL and well-being between starting and bench players and between 1-game and 2-game weeks were calculated using magnitude-based statistics. Results: Total weekly TL and acute-to-chronic workload ratio demonstrated high week-to-week variation, with spikes up to 226% and 220%, respectively. Starting players experienced a higher (most likely negative) total weekly TL and similar (unclear) well-being status compared with bench players. Game scheduling influenced TL, with 1-game weeks demonstrating a higher (likely negative) total weekly TL and similar (most likely trivial) well-being status compared with 2-game weeks. Conclusions: These findings provide college basketball coaches information to optimize training strategies during the in-season phase. Basketball coaches should concurrently consider the number of weekly games and player status (starting vs bench player) when creating individualized periodization plans, with increases in TL potentially needed in bench players, especially in 2-game weeks.

For many years the desire for money and winning in Division I athletics,  particularly in the sports of football (Football Bowl Subdivision) and men’s basketball, have encouraged colleges and universities to provide special admission for athletes with exceptional athletic ability, who in turn, often are less prepared to succeed academically. This has resulted in the widespread occurrence of unethical academic support practices (e.g., taking classes and writing papers for students and providing answers to exams) in order to maintain athletes’ eligibility and increase graduation rates to appease the public and to present the case that intercollegiate athletic are about education first. As one means of curbing academic misconduct, the authors recommend providing Division I football and basketball the option of playing their sport only without any academic eligibility requirement. Athletes who are struggling academically or lack academic commitment would no longer need to be bolstered by illegitimate academic support or less than accurate metrics. The present exploratory study sought to determine how many Division I football and basketball players would choose the option of playing their sport only versus playing and pursuing their degree under current National Collegiate Athletic Association Guidelines (NCAA) guidelines. The results showed that the majority would still choose to play and pursue their degree. Overall, the belief that one can play professionally did not diminish athletes’ desire to play and earn their degree.  However, there were also a percentage of athletes that believed they can play professionally and also desired to play their sport only.

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.

AbstractThe widespread proliferation of and interest in bracket pools that accompany the National Collegiate Athletic Association Division I Men’s Basketball Tournament have created a need to produce a set of predicted winners for each tournament game by people without expert knowledge of college basketball. Previous research has addressed bracket prediction to some degree, but not nearly on the level of the popular interest in the topic. This paper reviews relevant previous research, and then introduces a rating system for teams using game data from that season prior to the tournament. The ratings from this system are used within a novel, four-predictor probability model to produce sets of bracket predictions for each tournament from 2009 to 2014. This dual-proportion probability model is built around the constraint of two teams with a combined 100% probability of winning a given game. This paper also performs Monte Carlo simulation to investigate whether modifications are necessary from an expected value-based prediction system such as the one introduced in the paper, in order to have the maximum bracket score within a defined group. The findings are that selecting one high-probability “upset” team for one to three late rounds games is likely to outperform other strategies, including one with no modifications to the expected value, as long as the upset choice overlaps a large minority of competing brackets while leaving the bracket some distinguishing characteristics in late rounds.

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.

Background: Hand and wrist injuries (HWIs) are common in National Collegiate Athletic Association (NCAA) basketball players and can negatively affect performance. There is limited literature available on this topic. Purpose: To open a discussion on prevention strategies and encourage future research on HWIs in basketball athletes. Study Design: Descriptive epidemiology study. Methods: HWIs sustained by male and female NCAA basketball players during the 2009-2010 through 2013-2014 academic years and reported to the NCAA Injury Surveillance Program (NCAA-ISP) database were utilized to characterize the epidemiology thereof. Rates and distributions of HWIs were identified within the context of mechanism of injury, injury recurrence, and time lost from sport. Results: Over the 5-year period, 81 HWIs in women and 171 HWIs in men were identified through the NCAA-ISP database. These were used to estimate 3515 HWIs nationally in women’s basketball athletes and 7574 HWIs nationally in men’s basketball athletes. The rate of HWIs in women was 4.20 per 10,000 athlete-exposures (AEs) and in men was 7.76 per 10,000 AEs, making men 1.85 times more likely to sustain HWIs compared with women. In men, HWIs were 3.31 times more likely to occur in competition compared with practice, while in women, HWIs were 2.40 times more likely to occur in competition than in practice. Based on position, guards, both men and women, were the most likely to suffer HWIs. Conclusion: HWIs were common in collegiate basketball players. Most injuries were new, and the majority of players were restricted from participation for less than 24 hours. Men were more likely to be injured compared with women, and injuries were most common in the setting of competition for both sexes. The majority of injuries was considered minor and did not extensively limit participation; however, prevention and detection remain important for optimal performance.

Components Analysis

Due to the high number of variables reported from tracking systems, the interest in data reduction techniques has grown. To date, principal component analysis (PCA) has been performed in soccer, but since the results depend on the variables included, a lack of objectivity continues to be of concern. The aim of this study was to highlight the variables that compose the principal components (PC) in semi-professional soccer, including all variables extracted from tracking systems. Data were collected from a semi-professional Spanish team that participated in 10 matches. From more than 250 variables, the PCA grouped a total of 19 variables in six PCs, explaining 72% of players’ external load. All variables were related to centripetal force, high intensity running, and high-intensity efforts and short efforts. Interestingly, the first PC was composed of four variables related to centripetal force. The current exploratory analysis indicated that, in addition to traditional high-intensity displacement variables, force measures should also be considered in soccer match analysis due to their effect on a player’s external load.
