The aim of this case study was to describe the distinct approaches used by physical education (PE) teachers to accommodate students with disabilities in New York elementary school PE classes. The participants included 1 adapted PE specialist, 5 PE teachers, and 5 elementary school students with various impairments. Through thematic analysis, observations and interviews revealed 3 main approaches: (a) normalized instruction—traditional curriculum with no differentiation in the program; (b) differentiated instruction—adaptations tailored specifically to the needs of each student with disability; and (c) universally designed instruction based on the principles of Universal Design for Learning (UDL) and accessibility to all students. Differentiated instruction, entailing modifications in the program and pedagogical accommodations, was the most prevalent approach at the research site, but lessons based on UDL principles were also observed. In association, the 2 approaches (differentiated instruction and UDL) represented significant resources to accommodate students with disabilities in PE.

Despite the growing popularity of mindfulness and acceptance-based performance enhancement methods in applied sport psychology, evidence for their efficacy is scarce. The purpose of the current study is to test the feasibility and effect of a psychological training program based on Acceptance and Commitment Training (ACT) developed for ice hockey players. A controlled group feasibility designed study was conducted and included 21 elite male ice hockey players. The ACT program consisted of four, once a week, sessions with homework assignments between sessions. The results showed significant increase in psychological flexibility for the players in the training group. The outcome was positive for all feasibility measures. Participants found the psychological training program important to them as ice hockey players and helpful in their ice hockey development. Desirably, future studies should include objective performance data as outcome measure to foster more valid evidence for performance enhancement methods in applied sport psychology.

Lateral stability and weight transfer are important for successful stepping and are associated with falls in older adults (OAs). This study assessed the influence of step pacing frequency during medial–lateral stepping in place on body center of mass and lower limb movement in young adults, middle-aged adults, and OAs. Medial–lateral center of mass and stepping limb motion and lower limb loading data were collected. Center of mass motion decreased with increasing pacing frequency and increased to a lesser extent with decreasing pacing frequency. Step length was relatively resistant to changes in pacing frequency. OAs exhibited reductions in whole body and stepping motion compared with younger adults. OAs exhibited greater support limb loading. OAs adapt both postural and stepping strategies to successfully step under time-critical conditions.

The purpose of this study was to examine the types and perceived usefulness of questionnaires used by consultants in applied intervention work with athletes in 2003 and 2017, as well as to understand consultants’ perceptions of the advantages, limitations, and needs regarding the use of questionnaires in consulting. Sport psychology consultants in 2003 (n=96) and 2017 (n=106) completed a questionnaire that included Likert-scale questions as well as open-ended questions. The percentage of consultants who used questionnaires decreased from 83% in 2003 to 67% in 2017. Consultants in 2003 rated questionnaires as more useful than consultants in 2017, although the specific questionnaires used by consultants did not change extensively over the 14-year period. Advantages in using questionnaires included efficiency, structure of assessment, consensual validation, and credibility, while limitations included lack of relevance, undermining of athlete-consultant relationship, interpretive problems, and cost and lack of access.

Background: Prior work indicates that pedaling-related brain activation is lower in people with stroke than in controls. We asked whether this observation could be explained by between-group differences in volitional motor commands and pedaling performance. Methods: Individuals with and without stroke performed passive and volitional pedaling while brain activation was recorded with functional magnetic resonance imaging. The passive condition eliminated motor commands to pedal and minimized between-group differences in pedaling performance. Volume, intensity, and laterality of brain activation were compared across conditions and groups. Results: There were no significant effects of condition and no Group × Condition interactions for any measure of brain activation. Only 53% of subjects could minimize muscle activity for passive pedaling. Conclusions: Altered motor commands and pedaling performance are unlikely to account for reduced pedaling-related brain activation poststroke. Instead, this phenomenon may be due to functional or structural brain changes. Passive pedaling can be difficult to achieve and may require inhibition of excitatory descending drive.

This study compared performances of timed up and go test subtasks between 40 older people with preserved cognition, 40 with mild cognitive impairment, and 38 with mild Alzheimer’s disease. The assessment consisted of anamneses and timed up and go test subtasks (sit-to-stand, walking forward, turn, walking back, and turn-to-sit). Data were captured by Qualisys Track Manager software and processed by Visual3D software. The MATLAB program was applied to detect and analyze timed up and go test subtasks. All subtasks differentiated people with Alzheimer’s disease and preserved cognition, except the sit-to-stand subtask, which did not distinguish any group. The walking forward subtask differed older people with preserved cognition from mild cognitive impairment, specifically on minimum peak of knee, average value of knee, and hip (pitch axis) during stance phase. The walking back, turn, and turn-to-sit subtasks distinguished subjects with Alzheimer’s disease from mild cognitive impairment. The separated analysis of transition and walking subtasks is important in identifying mobility patterns among cognitive profiles.

We examined whether or not coherence between chest wall intercostal and oblique muscles changed as a function of lung volume excursion, alveolar pressure, and muscular demand. We also assessed the effects of acute expiratory threshold loading (ETL) on chest wall muscular control. A total of 15 healthy adults (7 males; average age = 28 years) completed maximum performance and ETL tasks. Chest wall surface electromyographic and kinematic recordings were made. Participants also performed a session of acute ETL. We showed that corticomuscular control of the chest wall varied as a function of lung volume excursion and muscular effort. Acute ETL had some effect on respiratory kinematics but not coherence.

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.
