This study aims to investigate the effects of Tai Chi Chuan (TCC) and brisk walking (BW) on balance and training duration for the two exercises to significantly improve balance. A total of 48 elderly women were randomly divided into three groups. The TCC and BW groups completed a 60-min intervention training program with five sessions weekly for 16 weeks. Single-leg standing balance was tested every 4 weeks. Results showed that all the variables with eyes open improved on the eighth week (p < .05) in the TCC group and on the 12th week (p < .01) in the BW group. All variables with eyes closed improved on the 12th week (p < .01) in the TCC group and on the 16th week (p < .05) in the BW group. The results showed that 12 and 16 weeks of TCC and BW, respectively were essential to improve balance with eyes closed among the women aged 60–70 years.

A fundamental issue in applied sport psychology is the development of competent professionals who can provide effective and ethical services to clients. The current study uses a qualitative longitudinal design to track the development of five novice sport psychology practitioners in their first year of practice. The research team analyzed and integrated data from surveys, interviews, and journals to understand the participants’ experiences and compare them to previous literature on practitioner development. Participants reported increased confidence and flexibility over time, and reduced their perceived anxiety and dependence on supervision. These changes were similar in nature to what has been reported for counseling trainees, but seemed to happen more quickly. These findings highlight important developmental characteristics of first year sport psychology practitioners, which can help graduate programs to tailor their supervision and training to their students’ needs.

Flikikammo is a troubling phenomenon in which athletes lose the ability to perform previously automatic backward moving gymnastics skills as a normal part of a routine. To better understand the effects of flikikammo over time, the confidence, perceived pressure, physical well-being, energy, and stress levels of gymnasts (n = 6) and cheerleaders (n = 4) were assessed weekly over 10 weeks. Half of the participants reported experiencing flikikammo at the start of the study, and half served as age, skill level, and sport-matched controls. Athletes with flikikammo indicated that pressure from coaches and higher energy levels were related to more severe flikikammo. For participants under the age of 18, higher levels of life stress positively correlated with flikikammo, but for those over 18, higher life stress was negatively correlated with flikikammo. These findings highlight the complexity of flikikammo and suggest that complex solutions may be needed to address flikikammo issues.

Postural sway does not differentiate between balance disorders. Head kinematics within a salient, immersive environment could potentially help identifying movement patterns that are unique to vestibular dysfunction. We describe a virtual park scene, where participants are asked to avoid a virtual ball approaching their head, to target dynamic balance and quantify head movement strategy. Sixteen patients with vestibular dysfunction and 16 healthy controls were wearing the Oculus Rift and performed the “park” scene on floor and stability trainers. Significant between-group differences emerged in head path (patients rotated their head sideways more), head acceleration (controls had higher acceleration, especially on translation movements), and peak frequency (controls peaked around the frequency of the ball whereas patients were variable). Those findings demonstrated good to excellent test–retest reliability. There were no significant between-group differences in postural sway parameters. Future studies should establish norms across different levels of balance dysfunction and investigate the underlying mechanism leading to the movement strategy observed.

Effective learning methods are essential for motor skill development and participation in children with low motor abilities. Current learning methods predominantly aim to increase declarative knowledge through explicit instructions that necessitate sufficient working memory capacity. This study investigated the roles of declarative knowledge and working memory capacity in explicit motor learning of children with low motor abilities. We studied both acquisition performance (i.e., performance during practice) and learning (i.e., the improvement in performance from pretest to posttest). After practice with explicit instructions, children with low motor abilities showed significant learning, albeit that improvement was relatively small. However, working memory capacity and declarative knowledge did not predict learning. By contrast, working memory capacity and declarative knowledge did predict performance during practice. These findings suggest that explicit instructions enhance motor performance during practice, but that motor learning per se is largely implicit in children with low motor abilities.

During sit-to-stand (STS), the vestibular system is highly stimulated in response to linear acceleration of the head and may play an important role, in addition to vision, for postural control. We examined the effects of aging on visual–vestibular interaction for postural control during STS in 15 young (22.5 ± 1.1 years) and 15 older (73.9 ± 5.3 years) participants. Vestibular information was manipulated using galvanic vestibular stimulation. Vision conditions involved normal (eyes open), suboptimal (blurring goggles), and no (eyes closed) vision. Older participants had significantly greater mediolateral peak-to-peak trunk roll (p = .025) and center of mass displacements (p < .001) than young participants. However, despite having greater mediolateral instability, older participants utilized similar strategies as young participants to overcome sensory perturbations during STS. Overall visual inputs were more dominantly used for mediolateral trunk control during STS than vestibular inputs.

Eating disorders (EDs) are common amongst athletes, yet few receive treatment. Given that athletes have a unique set of risk factors for eating disorders and are faced with additional barriers to treatment, new models outside of face-to-face treatment are necessary to reach the population and provide more affordable, tailored, evidence-based care. One solution is to use digital mental health programs to provide primary or supplemental therapy. Digital programs can provide accessibility and privacy, and recent advancements allow for more personalized online experiences. However, there have been no studies to date that integrate technology-based tools to address the especially high prevalence rates of EDs in athletes. This paper describes how an integrated model that includes online screening linked to guided self-help programs, all adapted specifically for athletes, can be used to provide prevention and intervention of EDs in athletes.

It is estimated that 1.6 million people in the United States are currently diagnosed with an eating disorder. Eating disorders (EDs) have high rates of morbidity and mortality and remain the most severe mental illness. Unfortunately, rates of EDs and disordered eating behaviors (DEBs) among athletes appear to be increasing. In this study, authors summarize ED-related risks that pose compromises in psychological and social functioning, medical health, and overall quality of life. The importance of early detection and formal evaluation in preserving the athlete’s health, well-being and sustaining successful sport participation, and performance are highlighted. Athlete-specific factors, which challenge the ease and accuracy of ED detection and assessment, are noted. The recommended components of effective ED assessment are identified, including use of self-report measures and clinical interviews conducted by ED certified and licensed professionals. The importance of being well informed in tenets of ED awareness, prevention and supporting early detection, and referral for formal ED assessment are noted. Conclusions reflect the vital roles that both the multidisciplinary sport personnel and the sport environment/culture play in reducing the serious health risks of DEBs and EDs. Each is needed to protect an athlete’s well-being while fostering safe and successful sport participation.

Purpose: The current study evaluated associations between exercise identity (Exercise Identity Scale; EIS), compulsive exercise (Compulsive Exercise Test; CET), and their association with Eating Disorder Examination – Questionnaire (EDE-Q) scores among adult runners registered for mid- and long-distance races (N = 282, 48.2% male). Methods: Runners of half and full marathon races completed the EIS, CET, and EDE-Q. Results: Regression analyses indicated that increased EIS, b = −.21, and CET, b = −3.25, scores contribute to decreased eating pathology amongst half-marathon runners; a significant interaction effect emerged for EIS × CET scores, b = .08, such that relations between EIS and EDEQ scores were significant among runners reporting either lower or higher CET scores. These associations were not demonstrated in marathon runners. Conclusions: Results suggest that it is beneficial to consider running status when addressing the effect that exercise identity and compulsive exercise may have on eating pathology in competitive runners.

The aim of the study was to investigate if and how body image, taken from a contextual perspective, contributes to the eating disorder history. This qualitative study investigated the process of eating disorder development in eight elite women athletes in at-risk sports. The results showed that the relationship between eating disorder symptomatology and the sports environment was clearly recognized by the elite women athletes. Contextual body image, more specifically negative body-evaluations and upward body comparisons, appeared as an important factor in the development of eating disorders, particularly in the athletic context. It became clear that the two aesthetic and two endurance athletes as well as the two weight-class athletes in rowing described quite negative body evaluations in the context of sport, while some of them also recognized an impact of body image experiences in daily life. However, for both judokas, their eating disorder had nothing to do with their body image but was attributed to the weight-classes in their sport and accompanying weight making. Several unique trajectories and individual eating disorder histories were distinguished which confirms the value of taking a qualitative approach in investigating eating disorders in sport. We also discovered links between what the athletes had reported as contributors to their eating disorder history and how they told their stories by combining content analysis and narrative inquiry. Furthermore, the present study also highlights several critical aspects for prevention and treatment that should support sport federations and clinical sport psychologists in taking appropriate actions to deal more effectively with eating disorders in athletes.
