Context:
Motherhood appears to be a catalyst in job turnover for female athletic trainers, especially those employed at the National Collegiate Athletic Association Division I level. However, most researchers examining this topic have investigated the perspectives of those who are currently employed rather than those who are preparing to enter the profession.Objective:
To evaluate female athletic training students'' perceptions of motherhood and retention.Design:
Qualitative study.Setting:
Athletic training education program.Patients or Other Participants:
A total of 18 female athletic training students volunteered to participate. They were enrolled in 1 Commission on Accrediting Athletic Training Education–accredited athletic training program and represented 3 levels of academic study.Data Collection and Analysis:
The participants responded to a series of questions related to work–life balance and retention in athletic training. Analysis of the data followed a general inductive process. Credibility was established by interpretive member checks and peer review.Results:
The first theme, clinical setting, speaks to the belief that work–life balance and retention in athletic training require an employment setting that fosters a family-friendly atmosphere and a work schedule (including travel) that allows for time at home. The second theme, mentorship, reflects the acknowledgment that a female mentor who is successful in balancing the roles of mother and athletic trainer can serve as a role model. The final theme, work–life balance strategies, illustrates the need to have a plan in place to meet the demands of both home and work life.Conclusions:
A female athletic trainer who is successfully balancing her career and family responsibilities may be the most helpful factor in retention, especially for female athletic training students. Young professionals need to be educated on the importance of developing successful work–life balance strategies, which can be helpful in reducing attrition from the profession.Key Words: athletic training careers, work–life balance, mentorsKey Points
- Balancing the demands of a career, parenthood, and life can be difficult for all professionals, including female athletic trainers, and may affect their choice of work setting and their decision to remain in or leave the profession.
- Among the factors that can help female athletic trainers in the collegiate setting attain work–life balance are supportive work and home environments, flexible schedules, and good time-management skills.
- Female athletic trainers who have learned to balance their career and family responsibilities can serve as role models for students and young professionals.

Context:Researchers have examined the physical activity (PA) habits of certified athletic trainers; however, none have looked specifically at athletic training students.Objective:To assess PA participation and constraints to participation among athletic training students.Design:Cross-sectional study.Setting:Entry-level athletic training education programs (undergraduate and graduate) across the United States.Results:Only 22.8% (252/1105) of athletic training students were meeting the American College of Sports Medicine recommendations for PA through moderate-intensity cardiorespiratory exercise. Although 52.3% (580/1105) were meeting the recommendations through vigorous-intensity cardiorespiratory exercise, 60.5% (681/1125) were meeting the recommendations based on the combined total of moderate or vigorous cardiorespiratory exercise. In addition, 57.2% (643/1125) of respondents met the recommendations for resistance exercise. Exercise habits of athletic training students appear to be better than the national average and similar to those of practicing athletic trainers. Students reported structural constraints such as lack of time due to work or studies as the most significant barrier to exercise participation.Conclusions:Athletic training students experienced similar constraints to PA participation as practicing athletic trainers, and these constraints appeared to influence their exercise participation during their entry-level education. Athletic training students may benefit from a greater emphasis on work-life balance during their entry-level education to promote better health and fitness habits.Key Words: exercise, leisure constraints, leisure-time exercise questionnaire, work-life balance
Key Points
- Athletic training students experienced similar constraints to physical activity participation as practicing athletic trainers.
- Structural constraints, such as lack of time due to work or studies, were the most significant barriers to exercise participation.
- Emphasizing work-life balance to athletic training students may promote greater opportunities for physical activity participation as both students and future professionals.

Compared with their nonathlete peers, collegiate athletes consume higher quantities of alcohol, drink with greater frequency, and exhibit an increased propensity to engage in heavy episodic drinking (ie, binge drinking), which often may result in alcohol-related consequences. Moreover, collegiate athletes are also more likely to engage in other maladaptive lifestyle behaviors, such as participating in physical fights and riding with an intoxicated driver, and less likely to engage in protective behaviors, such as wearing a helmet while operating a motorcycle, moped, or bicycle. Taken together, these behaviors clearly pose a health risk for student-athletes and increase the likelihood that they will experience an alcohol-related unintentional injury (ARUI). An ARUI represents a risk not only to the health and well-being of collegiate athletes but also to their athletic performances, collegiate careers, and potential professional opportunities. Therefore, athletic trainers need to be equipped with the knowledge and skills to provide face-to-face brief interventions to student-athletes presenting with ARUIs and to evaluate the effect of their involvement. We address potential action items for implementation by athletic trainers.Key Words: collegiate athletes, alcohol use, alcohol-related consequences, interventionsCompared with their nonathlete peers, collegiate athletes consume higher quantities of alcohol, drink with greater frequency, and exhibit increased propensities to engage in heavy episodic drinking (ie, binge drinking).1–3 Given their high-risk drinking behaviors, student-athletes are more likely to experience alcohol-related consequences.4,5 Compared with nonathletes, collegiate athletes also are more likely to engage in other maladaptive lifestyle behaviors, such as participating in physical fights and riding with an intoxicated driver, and less likely to engage in protective behaviors, such as wearing a helmet while operating a motorcycle, moped, or bicycle.6 Taken together, these behaviors clearly pose a health risk for student-athletes and increase the likelihood that they will experience alcohol-related unintentional injuries (ARUIs). An ARUI represents a risk not only to the health and well-being of collegiate athletes but also to their athletic performances, collegiate careers, and potential professional opportunities. Head athletic trainers (ATs) contend that alcohol abuse during and after athletic and social events continues to be an important concern for the health and safety of student-athletes.7In a recent cross-sectional study, Brenner et al8 observed that, overall, approximately 18% of collegiate athletes experienced ARUIs and most of these occurred during the athletes'' first and second years in school. Furthermore, they noted that 38% of collegiate athletes identified ARUI as a serious issue facing them.8 Moreover, approximately 56% of ATs recently reported that during the 2010–2011 academic year, they evaluated, treated, or referred an average of 3 ARUIs, most of which (63%) were classified as either moderate or severe.9Not surprisingly, Brenner et al9 observed that most ATs (73.4%) assert that ARUIs are a serious problem affecting the health of collegiate athletes, with 65.7% believing that they should be involved in the alcohol-related screening process for student-athletes. In addition, Brenner et al reported that most ATs contend that more training is necessary to help them (1) identify student-athletes with ARUIs (79%), (2) confront student-athletes with alcohol-related problems (79.7%), and (3) involve themselves in the referral process (92%).9 Furthermore, most head ATs have also expressed interest in becoming more involved with alcohol intervention programs.7 Considering that most university ATs already are substantially involved with regularly evaluating and treating non–alcohol-related injuries among student-athletes, ATs can and should play important roles in recognizing and evaluating ARUIs among student-athletes, especially given their expressed desire for more training in the intervention, prevention, and referral of ARUIs. Furthermore, ATs view themselves as “safe, approachable, care-taking individuals with whom athletes felt comfortable disclosing personal information,”10(p150) placing them in a unique position to provide appropriate intervention when necessary. 相似文献

Context:Work-life balance has been examined at the collegiate level from multiple perspectives except for the athletic trainer (AT) serving in a managerial or leadership role.Objective:To investigate challenges and strategies used in achieving work-life balance from the perspective of the head AT at a National Collegiate Athletic Association Division I university.Design:Qualitative study.Setting:Web-based management system.Results:Two higher-order themes emerged from our analysis of the data: organizational challenges and work-life balance strategies. The organizational challenges theme contained 2 lower-order themes: lack of autonomy and role demands. The work-life balance strategies theme contained 3 lower-order themes: prioritization of commitments, strategic boundary setting, and work-family integration.Conclusions:Head ATs are susceptible to experiencing work-life imbalance just as ATs in nonsupervisory roles are. Although not avoidable, the causes are manageable. Head ATs are encouraged to prioritize their personal time, make efforts to spend time away from their demanding positions, and reduce the number of additional responsibilities that can impede time available to spend away from work.Key Words: quality of life, supervisory role, retention
Key Points
- Work-life imbalance is inevitable, particularly in the collegiate setting, but is manageable.
- As do athletic trainers in nonsupervisory roles, head athletic trainers can experience work-life imbalance due to role overload and a lack of autonomy over work schedules.
- Head athletic trainers are encouraged to prioritize their personal time, try to spend time away from work, and reduce additional responsibilities that prevent spending time away from work.
- Expectations of the athletes and coaches for medical care during out-of-season training can limit the athletic trainer''s time away, particularly because many are responsible for more than 1 team.

A multilevel model of work-life balance (WLB) has been established in the sports management literature to explain interactions among organizational/structural, individual, and sociocultural factors and their effects on individual responses and attitudes toward WLB. These factors influence experiences and outcomes related to WLB.Objective
To examine individual and sociocultural factors that may influence perceptions of female athletic trainers (ATs) employed in the National Collegiate Athletic Association Division I setting, particularly any sex-specific influences.Design
Qualitative study.Setting
National Collegiate Athletic Association Division I.Patients or Other Participants
A total of 27 women (14 single with no children, 6 married with no children, 7 married with children) currently employed as full-time ATs in the Division I setting participated.Data Collection and Analysis
Participants responded to a series of open-ended questions via reflective journaling. Data were examined using a general inductive approach. Trustworthiness was established by multiple-analyst triangulation, member interpretive review, and peer review.Results
Participants recognized that their sex played a role in assessing WLB and a long-term career as an AT. In addition, they identified various individual- and sociocultural-level factors that affected their perceptions of WLB and attitudes toward a career goal.Conclusions
Our data suggested that female ATs may hold traditional sex ideologies of parenting and family roles, which may influence their potential for career longevity.Key Words: sex influence, quality of life, retention, attritionKey Points
- A traditional sex ideology of parenting and family roles may contribute to the persistence and departure of female athletic trainers in the National Collegiate Athletic Association Division I setting.
- Female athletic trainers preferred an adaptive lifestyle, but personal preferences and sociocultural factors also influenced their career decisions.
- Work-life balance is multifaceted, with various factors leading to experiences of conflict.

Context:
Professional responsibility, rewards and respect, and time for rejuvenation are factors supporting professional commitment for athletic trainers (ATs) in the high school setting. The inherent complexities of an occupational setting can mitigate perceptions of professional commitment. Thus far, evidence is lacking regarding professional commitment for ATs in other occupational settings.Objective:
To extend the literature on professional commitment of the AT to the collegiate setting.Design:
Qualitative study.Setting:
Collegiate.Patients or Other Participants:
Thirty-three Board of Certification-certified ATs employed in the collegiate setting (National Collegiate Athletic Association Division I = 11, Division II = 9, Division III = 13) with an average of 10 ± 8 years of clinical experience volunteered. Data saturation guided the total number of participants.Data Collection and Analysis:
Online journaling via QuestionPro was used to collect data from all participants. Two strategies, multiple-analyst triangulation and peer review, were completed to satisfy data credibility. Data were evaluated using a general inductive approach.Results:
Likert-scale data revealed no differences regarding levels of professional commitment across divisions. Two themes emerged from the inductive-content analysis: (1) professional responsibility and (2) coworker support. The emergent theme of professional responsibility contained 4 subthemes: (1) dedication to advancing the athletic training profession, (2) ardor for job responsibilities, (3) dedication to the student-athlete, and (4) commitment to education. Our participants were able to better maintain their own professional commitment when they felt their coworkers were also committed to the profession.Conclusions:
The collegiate ATs investigated in this study, regardless of division, demonstrated professional commitment propelled by their aspiration to advance the profession, as well as their dedication to student-athletes and athletic training students. Maintaining commitment was influenced by a strong sense of coworker support.Key Words: learning, professional responsibility, supportKey Points
- Collegiate athletic trainers were internally motivated and professionally committed to their roles as health care providers.
- Their professional commitment was propelled by their aspiration to advance the profession, dedication to student-athletes and athletic training students, and the value they placed on education.
- 1.How did ATs working in the collegiate setting characterize professional commitment?
- 2.Which factors positively influenced ATs in upholding their professional commitment over the course of their careers?

Context:
Sport-related concussion can affect athletes'' sport participation and academic success. With the recent emphasis on cognitive rest, student-athletes may benefit from academic accommodations (AA) in the classroom; however, athletic trainers'' (ATs'') perceived familiarity with, and use of, AA is unknown.Objective:
To assess secondary school ATs'' perceived familiarity with, attitudes and beliefs about, and incorporation of AA for student-athletes after sport-related concussion. A secondary purpose was to determine whether employment status altered familiarity and use of AA.Design:
Cross-sectional study.Setting:
Online survey.Patients or Other Participants:
Of 3286 possible respondents, 851 secondary school ATs accessed the survey (response rate = 25.9%; 308 men [36.2%], 376 women [44.2%], 167 respondents [19.6%] with sex information missing; age = 37.3 ± 10.1 years).Main Outcome Measure(s):
Participants were solicited via e-mail to complete the Beliefs, Attitudes and Knowledge Following Pediatric Athlete Concussion among Athletic Trainers employed in the secondary school setting (BAKPAC-AT) survey. The BAKPAC-AT assessed ATs'' perceived familiarity, perceptions, and roles regarding 504 plans, Individualized Education Programs (IEPs), and returning student-athletes to the classroom. Independent variables were employment status (full time versus part time), employment model (direct versus outreach), years certified, and years of experience in the secondary school setting. The dependent variables were participants'' responses to the AA questions. Spearman rank-correlation coefficients were used to assess relationships and Mann-Whitney U and χ2 tests (P < .05) were used to identify differences.Results:
Respondents reported that approximately 41% of the student-athletes whose sport-related concussions they managed received AA. Respondents employed directly by the school were more familiar with 504 plans (P < .001) and IEPs (P < .001) and had a greater belief that ATs should have a role in AA. Both the number of years certified and the years of experience at the secondary school were significantly correlated with perceived familiarity regarding 504 plans and IEPs.Conclusions:
The ATs employed directly by secondary schools and those with more experience as secondary school ATs were more familiar with AA. Understanding AA is important for all ATs because cognitive rest and “return to learn” are becoming more widely recommended in concussion management.Key Words: adolescent sport-related concussions, concussion management, 504 plans, Individualized Education ProgramsKey Points
- The patients in nearly one-half of the sport-related concussion cases managed by secondary school athletic trainers received academic accommodations.
- For proper management of and successful recovery from concussions, academic accommodations are often important.
- Athletic trainers should become more familiar with academic accommodations to ensure that student-athletes can return successfully to the classroom.

Context:
Professional commitment simply describes one''s obligation to his or her work. For athletic trainers (ATs), the demanding work environment and job expectations may affect their characterization of professional commitment. Our breadth of knowledge regarding professional commitment within athletic training is narrow.Objective:
To evaluate the professional commitment of ATs in the collegiate setting.Design:
Qualitative study.Setting:
Collegiate.Patients or Other Participants:
Thirty-three Board of Certification-certified ATs employed in the collegiate setting (National Collegiate Athletic Association Division I = 11, Division II = 9, Division III = 13) with an average of 10 ± 8 years of clinical experience volunteered. Data saturation guided the total number of participants.Data Collection and Analysis:
Online journaling via QuestionPro was completed by all participants. Multiple-analyst triangulation and peer review were conducted for data credibility. Analysis followed a general inductive method.Results:
Four themes speak to the factors that negatively affect ATs'' professional enthusiasm and commitment: (1) life stage, (2) work overload, (3) organizational climate, and (4) human resources. The latter 3 speak to the effect the workplace can have on ATs'' professional commitment, and the first speaks to the effect outside responsibilities can have.Conclusions:
Our results suggest that several of the factors that negatively influence the professional commitment of collegiate ATs are modifiable organizational components. Developing resiliency strategies at the individual and organizational levels may help to facilitate improved professional commitment for the AT.Key Words: resiliency, organizational climate, role overloadKey Points
- Professional commitment describes one''s emotional attachment to a profession, the sense of obligation to the profession, and the cost : benefit perception of departure from the profession.
- The professional commitments of collegiate athletic trainers were negatively affected by their life stage, work overload, organizational climate, and human resources.
- Work overload, organizational climate, and human resources are components that can be addressed at the organizational level to facilitate work-life balance and enhance professional commitment.

Context:Choosing to pursue an advanced degree in athletic training appears to indicate professional commitment and passion for the profession. Currently, there is a paucity of information regarding why some athletic trainers pursue enrollment in a postprofessional athletic training program (PPATP), indicating commitment to the profession, but later depart for another primary role outside of athletic training.Objective:To understand why athletic trainers invested in advanced training via a PPATP but then decided to leave the profession.Design:Qualitative study.Setting:Online data collection.Results:Two higher-order themes emerged regarding the career commitment of former athletic trainers who were PPATP graduates: (1) departure from an athletic training career and (2) partial continuance in athletic training. Two second-order themes emerged from the reasons for departure: (1) decreased recognition of value and (2) work-life imbalance. Finally, we identified 2 third-order themes from the participants'' reasons for departure because of a perceived lack of value: (1) low salary and (2) long, inconsistent hours worked.Conclusions:Most of our participants intended to stay in the profession when they chose to attend a PPATP. However, during role inductance in either the clinical experience of the PPATP they attended or early in their careers, they began to have thoughts of leaving mainly because of inadequate financial compensation, challenging work schedules, or both.Key Words: retention, attrition, career inductance
Key Points
- Despite their initial intentions to remain in the profession, athletic trainers who departed cited low salaries and long, inconsistent hours as the main factors in their decisions.
- Also influencing the decision to leave athletic training were decreased perceived value as a health care provider and work-life imbalance.

Context Some newly credentialed athletic trainers (ATs) pursue a postprofessional degree with a curriculum that specifically advances their athletic training practice. It is unknown how those postprofessional programs assist in their transition to practice.Objective To gain an understanding of initiatives used by postprofessional athletic training programs to facilitate role transition from student to professional during their graduate degree programs.Design Qualitative study.Setting Semistructured telephone interviews.Results Three facilitators of transition to practice emerged: orientation sessions, mentoring, and assistantship. Participants used orientation sessions ranging from a few hours to more than 1 week to provide and discuss program polices and expectations and to outline roles and responsibilities. Faculty, preceptors, and mentors were integrated into the orientation for the academic and clinical portions of the program. All participants described a mentoring process in which students were assigned by the program or informally developed. Mentors included the assigned preceptor, a staff AT, or peer students in the program. The clinical assistantship provided exposure to the daily aspects of being an AT. Barriers to transition to practice included previous educational experiences and time management. Participants reported that students with more diverse didactic and clinical education experiences had easier transitions. The ability to manage time also emerged as a challenge.Conclusions Postprofessional athletic training programs used a formal orientation session as an initial means to help the newly credentialed AT transition into the role. Mentoring provided both more informal and ongoing support during the transition.Key Words: mentoring, orientation, time management
Key Points
- Program directors used orientation sessions and mentoring to help support the transition from student to credentialed athletic trainer.
- The clinical assistantship provided the foundations for transition, as it conveyed role engagement.
- Mentoring was mostly informal but provided the ongoing support needed during the transition from student to credentialed athletic trainer.

The intercollegiate setting receives much of the scholarly attention related to work-life conflict (WLC). However research has been focused on the National Collegiate Athletic Association Division I setting. Multiple factors can lead to WLC for the athletic trainer (AT), including hours, travel, and lack of flexibility in work schedules.Objective
To investigate the experiences of WLC among ATs working in the non-Division I collegiate setting and to identify factors that contribute to fulfillment of work-life balance in this setting.Design
Qualitative study.Setting
Institutions in the National Collegiate Athletic Association Divisions II and III, the National Association of Intercollegiate Athletics, and the National Junior College Athletic Association.Patients or Other Participants
A total of 244 ATs (128 women, 114 men; age = 37.5 ± 13.3 years, experience = 14 ± 12 years) completed phase I. Thirteen participants (8 women, 5 men; age = 38 ± 13 years, experience = 13.1 ± 11.4 years) completed phase II.Data Collection and Analysis
For phase I, participants completed a previously validated and reliable (Cronbach α > .90) Web-based survey measuring their levels of WLC and work-family conflict (WFC). This phase included 2 WFC scales defining family; scale 1 defined family as having a partner or spouse with or without children, and scale 2 defined family as those individuals, including parents, siblings, grandparents, and any other close relatives, involved in one''s life. Phase II consisted of an interview. Qualitative data were evaluated using content analysis. Data source and multiple-analyst triangulation secured credibility.Results
The WFC scores were 26.33 ± 7.37 for scale 1 and 20.46 ± 10.14 for scale 2, indicating a moderate level of WFC for scale 1 and a low level of WFC for scale 2. Qualitative analyses revealed that organizational dimensions, such as job demands and staffing issues, can negatively affect WLC, whereas a combination of organizational and personal dimensions can positively affect WLC.Conclusions
Overload continues to be a prevalent factor in negatively influencing WLC and WFC. Supervisor and peer support, personal networks, and time away from the role positively influenced work-life balance and WFC. Athletic trainers are encouraged to support one another in the workplace, especially when providing flexibility in scheduling.Key Words: overload, personnel management, organizational supportKey Points
- Organizational factors influenced work-life conflict and work-life balance (WLB) for the athletic trainer.
- Overload was a prevalent negative influence on WLB.
- Supervisor and peer support, personal networks, and time away from the role positively influenced WLB.
- Athletic trainers should support each other in the workplace, and supervisors should encourage and support the concept of job sharing.

Despite the Psychosocial Strategies and Referral content area, athletic trainers (ATs) generally lack confidence in their ability to use this information.Objective:
The current study''s primary purpose was to determine (a) perceived psychological responses and coping behaviors athletes may present to ATs, (b) psychosocial strategies ATs currently use with their athletes, (c) psychosocial strategies ATs deem important to learn more about, and (d) ATs'' current practices in referring athletes to counseling or sport psychology services.Design:
Mixed-methods study.Setting:
Online survey containing both quantitative and qualitative items.Patients or Other Participants:
A total of 215 ATs (86 male, 129 female), representing a response rate of 22.50%.Main Outcome Measure(s):
The Athletic Training and Sport Psychology Questionnaire.Results:
Stress/anxiety (4.24 ± 0.82), anger (3.70 ± 0.96), and treatment adherence problems (3.62 ± 0.94) were rated as the primary psychological responses athletes may present upon injury. Adherence and having a positive attitude were identified as key determinants in defining athletes'' successful coping with their injuries. The top 3 selected psychosocial strategies were keeping the athlete involved with the team (4.57 ± 0.73), using short-term goals (4.45 ± 0.67), and creating variety in rehabilitation exercises (4.32 ± 0.75). The top 3 rated psychosocial strategies ATs deem important to learn more about were understanding motivation (4.29 ± 0.89), using effective communication (4.24 ± 0.91), and setting realistic goals (4.22 ± 0.97). Of the sample, only 59 (27.44%) ATs reported referring an athlete for counseling services, and 37 (84.09%) of those who had access to a sport psychologist (n = 44) reported referring for sport psychology services.Conclusions:
These results not only highlight ATs'' current use of psychosocial strategies but also their desires to increase their current knowledge and understanding of these strategies while caring for injured athletes.Key Words: psychology, clinical skills, professional preparedness, athletic trainingKey Points
- • Athletic trainers appear to be mindful of the psychological ramifications that athletes often experience as a result of their injuries.
- • Although athletic trainers apparently used some psychosocial strategies within injury rehabilitation, they also stressed the importance of learning more about these strategies.

Context:Fatigue is suggested to be a risk factor for anterior cruciate ligament injury. Fatiguing exercise can affect neuromuscular control and laxity of the knee joint, which may render the knee less able to resist externally applied loads. Few authors have examined the effects of fatiguing exercise on knee biomechanics during the in vivo transition of the knee from non–weight bearing to weight bearing, the time when anterior cruciate ligament injury likely occurs.Objective:To investigate the effect of fatiguing exercise on tibiofemoral joint biomechanics during the transition from non–weight bearing to early weight bearing.Design:Cross-sectional study.Setting:Research laboratory.Intervention(s):Participants were tested before (preexercise) and after (postexercise) a protocol consisting of repeated leg presses (15 repetitions from 10°–40° of knee flexion, 10 seconds'' rest) against a 60% body-weight load until they were unable to complete a full bout of repetitions.Results:The axial compressive force (351.8 ± 44.3 N versus 374.0 ± 47.9 N; P = .018), knee-flexion excursion (8.0° ± 4.0° versus 10.2° ± 3.7°; P = .046), and anterior tibial translation (6.7 ± 1.7 mm versus 8.2 ± 1.9 mm; P < .001) increased from preexercise to postexercise. No significant correlations were noted.Conclusions:Neuromuscular fatigue may impair initial knee-joint stabilization during weight acceptance, leading to greater accessory motion at the knee and the potential for greater anterior cruciate ligament loading.Key Words: knee, anterior cruciate ligament, axial loading
Key Points
- After closed chain exercise, participants demonstrated an increase in anterior tibial translation during simulated lower extremity weight acceptance.
- Observed alterations of knee biomechanics in a fatigued state may suggest increased anterior cruciate ligament strain during the latter part of the competition.

Context:Although lateral ankle sprains are common in athletes and can lead to chronic ankle instability (CAI), strength-training rehabilitation protocols may improve the deficits often associated with CAI.Objective:To determine whether strength-training protocols affect strength, dynamic balance, functional performance, and perceived instability in individuals with CAI.Design:Randomized controlled trial.Setting:Athletic training research laboratory.Intervention(s):Both rehabilitation groups completed their protocols 3 times/wk for 6 weeks. The control group did not attend rehabilitation sessions.Results:The resistance-band protocol group improved in strength (dorsiflexion, inversion, and eversion) and on the visual analog scale (P < .05); the proprioceptive neuromuscular facilitation group improved in strength (inversion and eversion) and on the visual analog scale (P < .05) as well. No improvements were seen in the triple-crossover hop or the Y-Balance tests for either intervention group or in the control group for any dependent variable (P > .05).Conclusions:Although the resistance-band protocol is common in rehabilitation, the proprioceptive neuromuscular facilitation strength protocol is also an effective treatment to improve strength in individuals with CAI. Both protocols showed clinical benefits in strength and perceived instability. To improve functional outcomes, clinicians should consider using additional multiplanar and multijoint exercises.Key Words: functional ankle instability, functional performance, rehabilitation, Star Excursion Balance Test
Key Points
- Proprioceptive neuromuscular facilitation is an alternate strength-training protocol that was effective in enhancing ankle strength in those with chronic ankle instability.
- Neither the resistance-band protocol nor the proprioceptive neuromuscular facilitation protocol improved dynamic balance or functional performance in individuals with chronic ankle instability.
