Measuring ice hockey skills in a repeated measures testing context: The effects of fatigue on skating efficiency, passing, agility and shooting
Purpose: Ice hockey testing traditionally consists of isolated, skills-specific tests that are performed in less realistic contexts. Global testing approaches should offer an improved assessment of players’ skills and performance fluctuations during a hockey game. This study aims to measure ice hockey players’ skills and analyze their fluctuations via a protocol that reproduces the demands of a hockey game. Methods: Fifty-nine hockey players (14.6 ± 2.1 years) participated in the study. The protocol involved four repeated measures assessing five components: speed, acceleration, passing, agility, and shooting, with supervised, 2-minute rest periods. Descriptive statistics and repeated measures ANOVAs were used to analyze performance fluctuations. Results: Findings revealed that the best scores were obtained at the first and second repetitions. A significant decline in performance was observed for speed, acceleration, and shooting (p < .01). Inversely, participants seemed to adapt to puck control and passing stations, as they became faster without decreasing skating abilities. Perceived exertion and recovery time increased during the protocol. Conclusions: In summary, performance was affected by fatigue starting the third repetition of the testing protocol, and should be considered when assessing players’ skills. This study demonstrated the feasibility of an on-ice testing protocol to evaluate players in a hockey-specific context. Applications in sport: This study demonstrated the feasibility of an “on-ice” testing protocol that represents a more realistic context for measuring players’ abilities. Such protocols allow coaches to evaluate the effects of fatigue on multiple determinants associated with performance in ice hockey.

Movement Competency Screen Predicts Performance in Female Military Academy Recruits
Musculoskeletal injuries in military populations are a leading cause for reduced physical readiness (15). Utilizing a screening tool that predicts physical performance and injuries could help identify recruits who need remedial training or conditioning. The Movement Competency Screen (MCS) identifies poor movement patterns and suggests safe load levels for individuals (8). This study sought to establish the predictive ability of the MCS for injuries and performance in United States Naval Academy (USNA) recruits over four years. Fifteen female and 26 male recruits completed the MCS upon entry into the academy. The recruits’ Physical Readiness Test (PRT) scores and injury data were collected for eight semesters. Correlations between MCS scores and recruits’ number of injuries, missed “duty days”, and region of injury were identified using Pearson correlation coefficients. Additionally, correlations between MCS scores and recruits’ overall PRT score, number of push-ups, curl-ups, and their 1.5-mile run time were calculated. Within the first year at USNA recruits’ MCS scores correlated with the number of injuries and missed “duty days”; however, this correlation was not sustained. Recruits also experienced the most injuries in the first year. For female recruits, higher MCS scores correlated with better PRT scores, number of push-ups, and 1.5 mile run times. With its high inter- and intra-rater reliability (12), the MCS could be used to identify poor movement patterns and guide remedial training to help prevent future injury. Further research should focus on a larger military population to determine if the MCS’s predictive abilities go beyond a military academy population.

Examining Perceptions of Baseball’s Eras: A Statistical Comparison
Professional baseball has endured many changes in rules, equipment, and competitive strategy over the course of its history. Because of such shifts, the modern era of Major League Baseball has been segmented into distinct eras. The purpose of this research was to determine how the perceptions of each era compared with the statistical outputs based on the measure of On-Base Plus Slugging Percentage (OPS), beginning with the 1901 season. Results were segmented by each era to determine any significant differences between the eras. Multiple regression and ANOVA were used to determine if perceptions for each era aligned with statistical findings. Results showed that perceptions for five of the seven eras matched, while perceptions of two eras did not. Results also showed significant statistical differences between the eras, indicating the way in which hitting and pitching contributed to winning percentage were unique for each era.

An Investigation of Youth Football Players’ Participation Motivations and Health Related Behaviors
Scientific studies investigating youth athletes have become increasingly broader and deeper since the first Youth Olympic Summer Games in 2010. This study examined the motivation factors that actually inspired the youth football athletes (YFAs) engaged in football practices and competitions and their health-related behaviors. Participants were 223 YFAs (age 16-18) from 10 high schools of New York City, USA. Adapted Questionnaire of Football Athlete’s Motivation and Health Related Behaviors (AQFAMHRB) was employed for data collection. The AQFAMHRB contains 19 questions examining participants’ motivation factors (MFs) and 27 questions investigating health-related behaviors. Data analysis included a 2 Supports (By-parents, By-school) x 2 Goal-Settings (For professional, For non-professional) MANOVA and other suitable methods. The top three scores from the 19 MFs from the AQSAMHRB were: “High technical-content” of Football, “For develop unique skill”, and “For shape body”, all three of these MFs are in the ‘Intrinsic motivation’ category and possess higher impact power on these YFAs’ participation motivation. The 2 x 2 MANOVA revealed that: no significant difference exists in the ‘Supports’ aspect (p >.70); however, significant difference was found in ‘Goal-settings’ (p < .00). Then a follow-up MANOVA determined: 13 out of 19 MFs comparisons in “Goal-settings” showed significant difference (p <. 05) with ‘For professional’ scored higher than ‘For non-professional’. The following MFs possess higher impact on YFAs: ‘to contest winners’, ‘to become a professional player’, ‘to establish prestige’, and ‘to become a coach’. Besides, both intrinsic and extrinsic MFs have significant impact on these YFAs’ motivations. Who “Support” their engagement is not the determinant but what goals the YFAs have set-up for themselves matter. Furthermore, to the 27 health-related behaviors in the AQSAMHRB, frequency and percentage data were summarized and analyzed. Findings from this aspect provided the first hand information about the YFAs’ ‘Eating Habits’, ‘Nutrition Knowledge and Status’, ‘Risk Behaviors’, and ‘Hygiene Behaviors’. These features of the YFAs’ health-related behaviors possess important meanings for improving YFAs’ coaching and management. (more…)

Playing with Pain: Social Class and Pain Reporting among College Student-Athletes
Socio-economic class affects a variety of health outcomes – this includes the experience of pain. Little work, however, explores how class affects pain experiences of college student-athletes. This gap is notable given injuries frequently occur in this population. We argue that lower class student-athletes will ironically be more likely to experience pain but less likely to report it. We find evidence for this claim with a large survey of student-athletes from a major National College Athletic Association conference. We further present evidence that class may influence pain reporting via identity, experiential, and social pathways. Our results highlight how potentially vulnerable student-athletes may “play with pain.” The findings also suggest that practitioners should pay particular attention to self-reports of pain by lower class student-athletes.
