Female Competitive Powerlifters relationship with Body Image: Utilising the Multidimensional Body Image Self Relations Questionnaire (MBSRQ)

Abstract

Purpose: There is growing evidence to suggest that competitive female athletes in certain sports that over scrutinize their body image may experience undesirable mental health outcomes. However, limited research addresses this issue in strength sports with weight class requirements. One such sport is powerlifting, which comprises the squat, bench – press and deadlift. Methods: This study used the Multidimensional Body Image Self Relations Questionnaire (MBSRQ), which recruited 174 female participants across the following subgroups. Powerlifters (P) (n = 66), Active Subjects (AF) (n = 50), Body Image sports (BI) n = 23) and Other Sports (OS) (n = 36). Results: One–way ANOVA showed significant (p < 0.05) results between all groups across seven of the nine MBSRQ subscales. Bonferroni comparisons revealed that there were ten other significant results between these groups. Conclusions: Overall, the results showed that female powerlifters expressed healthier and lower perceptions of negative body image concerns. Furthermore, female powerlifters did not present scores consistent with controlling bodyweight or fixating about being overweight. Instead, these results showed a focus on performance and health improvements. Active subjects presented the most fixation on their body weight and appearance. Applications in Sport: The study concludes that female powerlifters present healthy body image perceptions compared to the other female sporting/active groups. This may be due to the objective outcomes of the sport not relying on socially subjective assessment for validation.

Establishing Normative Reference Values for the Utah Seated Medicine Ball Throw Protocol in Adolescents

Abstract:

The seated medicine ball throw (SMBT) is a field test intended to assess upper-body muscular power by measuring the maximal distance an individual can throw a medicine ball from an isolated, seated position (25). The SMBT has been used to assess upper-body power in various populations and to establish concurrent validity for other measures of upper-body power such as the bench press power test and the plyometric push-up. The SMBT is less costly and simpler to incorporate into a field test battery than other upper body power assessments. While the SMBT is a valid, reliable field test for upper-body power, normative reference standards for most populations, including adolescent (12-15 years old) physical education students, do not exist. Purpose: This study reports distances thrown in the SMBT to establish normative reference values in male and female physical education students, ages 12-15 years old. Methods: One hundred thirteen untrained male and female physical education students aged 12-15 years performed the SMBT field test three times on a single testing day. Participants threw a 2 kg medicine ball with a 19.5 cm diameter while seated on the floor with the upper torso against the wall (legs extended, trunk angle 90°). Likewise, age, height, and body mass were assessed. Results: Participant data was separated by age gender for analysis. Mean and standard deviation for the SMBT for males was 4.3 ± 0.7 m and 5.2 ± 0.8 m for ages 12-13 and 14-15, respectively, and for females was 3.4 ± 0.5 m and 3.7 ± 0.5 m for ages 12-13 and 14-15, respectively. Pearson correlation coefficients (i.e. PCCS or r) were calculated for trial pairs (i.e. T1 vs T2, T2 vs T3, T3 vs T1) for both female and males at age groupings of 12-13 and 14-15. The aforementioned PCCs ranged from r = 0.85-0.97. Normative reference values as percentile ranks for the SMBT scores for age groups 12-13 and 14-15 among males and females, respectively, were also established. Conclusion: The data presented provides an initial set of normative reference standards for coaches and students to determine upper-body muscular power using the SMBT.

Injury Prevalence in Brazilian Jiu-Jitsu and Mitigation Strategies for Brazilian Jiu-Jitsu Practitioners and Instructors: A Literature Review

Abstract:

Purpose: This article synthesizes the peer-reviewed literature about injury prevalence in Brazilian Jiu-Jitsu (BJJ) and strategies to mitigate injuries. It is critical to implement injury prevention initiatives necessary to reduce injury rates among BJJ students since injuries are barriers to continued training and learning. A reduction in injuries allows athletes to compete in their sports for longer periods of time and to receive its physical, psychological, and social benefits. Methods: A qualitative, narrative review was implemented. Results: This literature review analyzes BJJ’s history and its significance to combat sports and as a fighting system, along with how it shapes the lives of those who study BJJ. In addition, injury prevalence in BJJ and types of injuries are discussed in detail, including risk reduction and mitigation strategies. Conclusions: Curriculum might play a role in reducing risk and a possible nexus between how adult students learn, how instructors teach, and student injuries. Applications in Sport: The application of adult learning theory may help reduce injuries in BJJ.

Andrew Alstot is an associate professor in the department of Kinesiology at Azusa Pacific University, primarily teaching in the Graduate Physical Education program. His research focus is on the use of the principles of applied behavior analysis in physical activity settings to improve exercise, skill, motivation, and social behavior. His teaching goals are to help to develop quality teachers, coaches, administrators, and other physical activity professionals to deliver research-based physical activity instruction and administration.

Effects of a Token Economy on Exercise Intensity and Intrinsic Motivation

Abstract

Purpose – Token economies, systems that use a variety of rewards to target behavior, have been shown useful in improving several physical activity-related behaviors. Yet, there is conflicting research on rewards-based systems’ impact on intrinsic motivation. When using rewards to improve behavior, it is recommended they be systematically withdrawn as time progresses. However, the effects of systems that withdraw rewards on exercise behavior and intrinsic motivation is unknown. Therefore, the purpose of the study was to examine the use of a token economy targeting exercise behavior and its impact on intrinsic motivation.

Methods – Participants rode a stationary bike for several baseline sessions where no rewards were administered; mean revolutions per minute (RPM) were calculated for each session. Then, participants were provided performance-based rewards on one of two schedules of reinforcement: (1) rewards were provided consistently across all token sessions or (2) rewards were systematically withdrawn with each subsequent token session. Intrinsic motivation was measured before the study and at the end of the last token session.

Results – Both rewards systems were effective in improving exercise intensity, with both groups showing distinct improvement in mean RPM during token sessions. Further, the system that withdrew rewards indicated no detriment to intrinsic motivation and for some, an improvement.

Conclusions and Applications in Sport – Fitness professionals, coaches, and educators may be able to use extrinsic rewards to improve exercise behavior and, if implemented properly, have no negative impact on their clients’, athletes’, and students’ intrinsic motivation for engaging in exercise.

The Impact of the Number of Student Athletes on Burnout and Work-Family Conflict of High School Athletic Trainers

ABSTRACT

Context: The relationship between clinician’s perceptions of patient care and burnout and work-family conflict (WFC) has not been examined as closely. In the high school setting, where athletic trainers often work as the only clinician and/or have a high volume of patients it is important to determine if experiences of burnout and WFC impacts perceptions of patient care.

Objective: Determine if any relationship exists between burnout and WFC and athletic trainer’s perceptions of patient care.

Design: Cross-sectional study

Setting: Online web-based survey

Patients or Other Participants: Athletic trainers were emailed through the Athletic Training Location and Services (ATLAS) database and invited to participate. Data from 573 (n = 373 (65.1%) women, n = 195 (34.2%) men, n = 1 (0.2%) transgender woman, n = 1 (0.02%) not listed, and n = 2 (0.3%) Prefer Not to Answer) were included in data analysis.

Main Outcome Measure(s): Data analyzed for this study included basic demographic information, the Copenhagen Burnout Inventory, a Work-Family Conflict Scale, and 5 questions specific to patient care (open-ended and ranking).

Results: Overall, participants reported low levels of burnout and WFC. The majority (55.7%) were satisfied with the time they had to deliver patient care and (65.7%) the care they were able to deliver. Stress was most often selected as a factor that negatively impacted patient care, while exercise was most commonly selected as the factor that positively impacted patient care. Participants who were satisfied with patient-care had lower strain-based conflict (U = 32441.0, p = .030) and participants who were satisfied with time for patient care had lower total WFC (U = 29174.5, p < .001).

Conclusions: Student athlete number and interactions do not appear to be a source of burnout or WFC among high school athletic trainers. Work-related factors and personal well-being and mental-health appear to impact clinicians’ perceptions of care delivered to patients.
