Acute Effects of Exercise Breaks on Attention and Working Memory During a University Lecture: A Group-Randomized Controlled Trial

Objective: This study investigated the acute effects of exercise breaks on attention and working memory during lectures among third-year physical therapy students.Material and Methods: In total 65 participants were randomly assigned to exercise breaks (N=22), game breaks (N=21), and no breaks (N=22). The lecture was divided into two parts. Participants watched each part of a 50-minute computer-based video lecture. The present study examined the heart rate, perception, attention, and working memory impact of 5-minute breaks. The exercise breaks group performed a series of callisthenic exercises, the game breaks group played a computer game, and the no breaks group watched the entire lecture continuously without breaks. The differences in means for variables among each group were compared using a 3x2 repeated measure Multivariate Analysis of Covariance (MANCOVA).Results: Exercise breaks during lectures facilitated a positive impact on the modulation of shifting working memory in comparison to game breaks and non-exercise breaks (p-value<0.05). Significant pre-test to post-test in shifting working memory improvements were found in the exercise breaks group (F(2,62)=4.266, p-value=0.018). The variation in mean shifting working memory was 12.1 percent of the effect (np2=0.121). This improvement aligned with better learning results, especially when assessed for immediate outcomes. Conclusion: Exercise breaks during academic lectures demonstrated a statistically significant impact on shifting working memory. Consequently, further investigations are required to explore the enduring impacts of exercise breaks on cognitive functions in the long term. Additionally, determining the optimal duration of exercise breaks and lecture lengths is essential for guiding university teaching practices.

Sex Differences in Physiological Responses to a National Collegiate Athletic Association Division I Soccer Season.

McFadden, BA, Walker, AJ, Cintineo, HP, Bozzini, BN, Sanders, DJ, Chandler, AJ, and Arent, SM. Sex differences in physiological responses to a national collegiate athletic association division I soccer season. J Strength Cond Res XX(X): 000-000, 2024-Identifying physiological changes that occur in response to workload demands can help to elucidate athlete management and recovery strategies. The purpose of this study was to compare the physical and physiological demands between men and women throughout the course of a collegiate soccer season. Men (N = 23) and women (N = 26) soccer players participated in blood draws before preseason (T1) and every 4 weeks thereafter (T2-T4). Workload was determined at all practices and games via heart rate and global positioning satellite monitoring systems. Repeated measures multivariate analysis of variance and linear mixed models were used to assess workload and biomarker responses throughout the season (p < 0.05). Both teams experienced the highest workloads during the first 4 weeks of the season (p < 0.05), which was followed by several biomarker perturbations. Sex-by-Time interactions were observed for total cortisol, growth hormone, insulin-like growth factor-1, thyroxine, thyroid-stimulating hormone, vitamin D, and omega 3 fatty acid index (p < 0.05). Additional Sex effects were observed for free and total testosterone, estrogen, prolactin, sex-hormone binding globulin, creatine kinase, and iron levels (p < 0.05). Women soccer players experienced further Time effects for free cortisol, iron, ferritin, and percent transferrin saturation (p < 0.05). Male soccer players experienced additional Time effects for total testosterone, estrogen, creatine kinase, interleukin-6, triiodothyronine, and ferritin (p < 0.05). Despite similar patterns of change in workloads, differential fluctuations in physiological markers were observed between the sexes. Understanding sex differences in response to comparable workloads may enhance exercise prescriptions for better athlete management plans. Additional strategies to increase iron may be warranted in female athletes.

Feature analysis of joint motion in paralyzed and non-paralyzed upper limbs while reaching the occiput: A cross-sectional study in patients with mild hemiplegia.

The reaching motion to the back of the head with the hand is an important movement for daily living. The scores of upper limb function tests used in clinical practice alone are difficult to use as a reference when planning exercises for movement improvements. This cross-sectional study aimed to clarify in patients with mild hemiplegia the kinematic characteristics of paralyzed and non-paralyzed upper limbs reaching the occiput. Ten patients with post-stroke hemiplegia who attended the Department of Rehabilitation Medicine of the Jikei University Hospital and met the eligibility criteria were included. Reaching motion to the back of the head by the participants' paralyzed and non-paralyzed upper limbs was measured using three-dimensional motion analysis, and the motor time, joint angles, and angular velocities were calculated. Repeated measures multivariate analysis of covariance was performed on these data. After confirming the fit to the binomial logistic regression model, the cutoff values were calculated using receiver operating characteristic curves. Pattern identification using random forest clustering was performed to analyze the pattern of motor time and joint angles. The cutoff values for the movement until the hand reached the back of the head were 1.6 s for the motor time, 55° for the maximum shoulder joint flexion angle, and 145° for the maximum elbow joint flexion angle. The cutoff values for the movement from the back of the head to the hand being returned to its original position were 1.6 s for the motor time, 145° for the maximum elbow joint flexion angle, 53°/s for the maximum angular velocity of shoulder joint abduction, and 62°/s for the maximum angular velocity of elbow joint flexion. The numbers of clusters were three, four, and four for the outward non-paralyzed side, outward and return paralyzed side, and return non-paralyzed side, respectively. The findings obtained by this study can be used for practice planning in patients with mild hemiplegia who aim to improve the reaching motion to the occiput.

Old Habits Die Hard: Regression in Learning and Study Strategies Inventory Scores in PharmD Students

ObjectivePrior studies have demonstrated that “learning to learn” (L2L) courses can lead to significant improvements in students’ Learning and Study Strategies Inventory (LASSI) scores immediately following the course. This study aimed to analyze whether improvements in LASSI scores are sustained 1 year following an L2L elective course. MethodsFirst-year pharmacy students in the classes of 2024 and 2025 completed the LASSI at the start of the fall semester and again immediately following an L2L course. One year later, during the second professional year, students completed the LASSI a third time. Repeated-measures multivariate analysis of variance was used to analyze within-participant differences in LASSI scores across each of the 10 LASSI scales. Univariate analysis of variance with Bonferroni correction was used for pairwise comparison. ResultsA total of 119 students completed all 3 LASSI assessments. LASSI scores improved in all 10 scales following completion of the L2L course. However, 1 year after the completion of the course, there was a statistically significant regression in all 10 scale scores (Wilks’ Λ [20,98] = 8.7). Among the 10 scales, scores for the Attitude and Concentration scales were statistically significantly lower during the second professional year relative to baseline at the start of the first professional year. Selecting Main Ideas was the only scale with a higher score during the second professional year relative to baseline. ConclusionDespite marked improvements in LASSI scores following the implementation of a “learning to learn” course for first-year pharmacy students, the improvements were not sustained after 1 year.

Ironic processes of concentration and suppression under pressure: A study on rifle shooting in Norwegian elite biathletes.

This study examined how priming attentional and negative cues affected participants' shooting performances toward ironic error targets under cognitive load conditions in Stroop task across two experiments. Semi-elite biathletes (Experiment 1, n = 10; Experiment 2, n = 9) participated in the study. The study used a within-subject quasi-experimental design, particularly a one-way repeated measures multivariate analysis of variance and a 2 × 2 fully repeated measures analysis of variance, to determine the participants' hit rates and shooting response times (RTs). In both experiments, the participants completed the reverse-Stroop-based target shooting performance under low- and high-cognitive load conditions while receiving frequent priming attentional and negative cues. The findings from Experiment 1 suggest that regulating repetitive priming attentional thoughts is efficacious in mitigating the likelihood of ironic performance errors and interference effects. The results of Experiment 2 show that repetitive priming negative cues resulted in negligible ironic error hit rates and slower RTs in target hits under high-cognitive load conditions. The Bayesian analyses provided evidence supporting the null hypotheses. Trying to control repetitive priming attentional and negative thoughts reduces ironic performance errors to a similar degree under cognitive load conditions among biathletes, regardless of interference effects. Further research is needed to determine the effectiveness of suppressing task-relevant negative instructions in reducing the likelihood of ironic performance errors under pressure.

Transference of outdoor gait-training to treadmill running biomechanics and strength measures: A randomized controlled trial

Outdoor gait-training has been successful in improving pain and reducing contact time during outdoor running for runners with exercise-related lower leg pain (ERLLP). However, it is unclear if these adaptations translate to gold standard treadmill running and clinical strength assessments. The study purpose was to assess the influence of a 4-week outdoor gait-training intervention with home exercises (FBHE) on treadmill running biomechanics and lower extremity strength compared to home exercises alone (HE) among runners with ERLLP. Seventeen runners with ERLLP were randomly allocated to FBHE and HE groups (FBHE: 3 M, 6F, 23 ± 4 years, 22.0 ± 4.6 kg/m2; HE: 3 M, 5F, 25 ± 5 years, 24.0 ± 4.0 kg/m2). Both groups completed eight sessions of home exercises over 4 weeks. The FBHE group received gait-training through wearable sensors to reduce contact time. Treadmill running gait and clinical strength assessments were conducted at baseline and 4-weeks. Multivariate repeated measures analyses of variance were used to assess the influence of group and timepoint for all outcomes. The FBHE group demonstrated significantly decreased contact time at 4-weeks compared to baseline and the HE group (Mean Difference [MD] range: −42 ms – −39 ms; p-range: <0.001–0.02). The FBHE group had significantly increased cadence (MD: +21 steps/min; p = 0.003) and decreased loading impulse (MD: −51, p < 0.001) during treadmill running at 4-weeks compared to the HE group. Strength did not significantly differ adjusting for multiple comparisons (p > 0.007). The outdoor FBHE intervention transferred to favorable changes in treadmill running biomechanics. Clinicians treating runners with ERLLP patients should implement data-driven outdoor gait-training to maximize patient benefits across running locations.

Contributing to 'a sense of purpose' - Evaluating consumer recovery progress after attending a therapeutic-recreation intervention programme: A quantitative analysis.

The recommended objective for mental health plans and policies is the adoption of recovery approaches to mental healthcare. Mental health recovery is no longer defined by symptom resolution but as a journey towards a meaningful life from the consumer's own perspective. Recovery approaches focus on consumers' strengths, feelings of well-being and the achievement of personal goals. Designing recovery-oriented interventions is crucial for supporting people in their personal recovery journey. This study sought to evaluate how attending a recovery-oriented intervention impacts the recovery of attending people living with serious mental illness. A quasi-experimental approach was utilised to examine changes in self-reported recovery progress in a purposive sample of consumers living with enduring mental illness (N = 105). Recovery progress was evaluated via the Recovery Assessment Scale - Domains and Stages (RAS-DS). Data were collected at entry and exit to a therapeutic recreation programme grounded in principles of recovery-oriented care and social contact theory. Pre-post scores were analysed via a repeated-measures multivariate analysis of variance (RM-MANOVA) per the four RAS-DS recovery domains. After attending the therapeutic recreation programme, consumer recovery scores significantly increased in the functional, personal, and social recovery RAS-DS domains as measured by 'Doing Things I Value', 'Looking Forward', and 'Connecting and Belonging' (respectively). No changes were observed to consumers' clinical recovery progress, as assessed via the recovery domain 'Mastering my Illness'. The results of this study demonstrate that therapeutic recreation camps can provide a recovery-based approach to mental healthcare, with positive effects on the three areas of: a purposeful life; connection and belonging; and optimism and hope. Recovery Camp has been previously identified by the Productivity Commission as having potential person-centred recovery benefits for mental health consumers. The results of this study now establish these benefits as evidence based and can be used to guide mental health practice and policy for the implementation of therapeutic recreation camps for mental health recovery.

The effects of flipped learning and gamification on nursing students’ patient safety education: A mixed method study

BackgroundThe importance of enhancing education to promote nursing students’ patient safety competency is increasing. Hence, implementing diverse educational programs and assessing their outcomes is essential. ObjectivesTo examine the effects of flipped learning and gamification on nursing students’ patient safety education. DesignA mixed-method design employing a quasi-experimental design with a pre-post control group design and qualitative thematic analysis. MethodsThe study was conducted at a South Korean university in W City from September to December 2022. It included 55 s-year nursing students. The experimental group (n = 28) participated in a 30-h patient safety education course using flipped learning and gamification, whereas the control group (n = 27) received only written patient safety education materials. Learning motivation, collective efficacy, patient safety competency, and game evaluations were measured. Data were analyzed using the χ2 test, Fisher's exact test, t-test, repeated-measures multivariate analysis of covariance, repeated measure analysis of covariance, and generalized estimating equations. Self-reflection journals on game participation experiences were analyzed using qualitative thematic analysis. ResultsLearning motivation scores did not differ significantly between groups for time, or interactions between groups and time, but collective efficacy and patient safety competency scores showed significant differences in the interactions between groups and time. The experimental group showed a high satisfaction score in game evaluation. Qualitative analyses were used to extract four themes—three positives: “fun and immersion differentiated from existing classes,” “improved the learning outcomes and learning motivation,” and “realized the value of collaboration and communication,” and one negative: “feeling down due to unfamiliarity.” ConclusionsThis program creates positive learning experiences and enhances nursing students’ collective efficacy and patient-safety competencies. It is expected to be utilized in various future nursing courses.

Relationship Between Running Biomechanics and Core Temperature Across a Competitive Road Race.

Outdoor races introduce environmental stressors to runners, and core temperature changes may influence runners' movement patterns. This study assessed changes and determined relationships between sensor-derived running biomechanics and core temperature among runners across an 11.27-km road race. Core temperatures would increase significantly across the race, related to changes in spatiotemporal biomechanical measures. Cross-sectional cohort study. Level 3. Twenty runners (9 female, 11 male; age, 48 ± 12 years; height, 169.7 ± 9.1 cm; mass, 71.3 ± 13.4 kg) enrolled in the 2022 Falmouth Road Race were recruited. Participants used lightweight technologies (ingestible thermistors and wearable sensors) to monitor core temperature and running biomechanics throughout the race. Timestamps were used to align sensor-derived measures for 7 race segments. Observations were labeled as core temperatures generally within normal limits (<38°C) or at elevated core temperatures (≥38°C). Multivariate repeated measures analyses of variance were used to assess changes in sensor-derived measures across the race, with Bonferroni post hoc comparisons for significant findings. Pearson's r correlations were used to assess the relationship between running biomechanics and core temperature measures. Eighteen participants developed hyperthermic core temperatures (39.0°C ± 0.5°C); core temperatures increased significantly across the race (P < 0.01). Kinetic measures obtained from the accelerometers, including shock, impact, and braking g, all significantly increased across the race (P < 0.01); other sensor-derived biomechanical measures did not change significantly. Core temperatures were weakly associated with biomechanics (|r range|, 0.02-0.16). Core temperatures and kinetics increased significantly across a race, yet these outcomes were not strongly correlated. The observed kinetic changes may have been attributed to fatigue-related influences over the race. Clinicians may not expect changes in biomechanical movement patterns to signal thermal responses during outdoor running in a singular event.

Effect of increasing cognitive activity participation on default mode network in older adults with subjective cognitive decline: a randomised controlled trial

BackgroundHaving more cognitive activities may prevent dementia, but its evidence of modulating the functional brain network is limited. This randomised controlled trial (RCT) investigated the effect of increased cognitive activity participation on the default mode network (DMN) in older adults who had already been having regular cognitive activity participation and experiencing subjective cognitive decline (SCD). MethodsCommunity-living Chinese individuals aged 55 to 75 years with regular practice of Chinese calligraphy and screened positive for SCD (but negative for mild cognitive impairment or dementia) were randomly allocated to either the intervention or control group. Over 6 months, the intervention group doubled their weekly calligraphy practice time, while the control group maintained their usual amount of practice. The primary outcome was functional connectivities (FCs) of DMN, with pre-specified regions of interest including medial prefrontal cortex [mPFC], inferior parietal lobe [IPL], hippocampal formation [HF], posterior cingulate cortex [PCC], and lateral temporal cortex [LTC]. FC changes were compared using repeated measures multivariate analysis of variance (MANOVA). This study is registered at the Chinese Clinical Trial Registry, ChiCTR1900024433. FindingsBetween 15 January 2020 and 31 December 2021, 112 individuals consented and completed the baseline assessment. The participants, who had a mean age of 66·3 [SD 4·3] years, with 83 (74%) being women, had been practising calligraphy for an average duration of 9·7 years before enrolment and, in the preceding six months, for an average of 3·1 hours per week. 96 (86%) completed the post-intervention fMRI scan. Significant between-group differences were observed in the FCs between mPFC and right LTC (group difference=0·25 [95% CI=0·06-0·44], p=0·009), mPFC and right IPL (0·23 [0·06-0·39]; p=0·007), left HF and right LTC (0·28 [0·002-0·57]; p=0·04), and left HF and right IPL (0·34 [0·09-0·60]; p=0·009). InterpretationOur findings, which reveal positive neuromodulatory effects with increased calligraphy practice, highlight the importance of engaging more in cognitive activities in late life for better brain health.

Effects of a neuropsychosocial teleassistance intervention on social cognition and health-related quality of life of pediatric patients with neuromuscular diseases.

This study aimed to determine the effects of a neuropsychosocial teleassistance group-based intervention on improving social cognitive functioning and health-related quality of life (HRQoL) in pediatric neuromuscular diseases (NMD). Thirty-five pediatric patients with NMD were assigned to the neuropsychosocial intervention program (n = 20) or waiting list control condition (n = 15). The intervention group received an integrative approach that combines training in social cognition with cognitive behavioral therapy. All participants completed a neuropsychological and clinical assessment at baseline and follow-up, which included tests of social cognition, both for emotion recognition and theory of mind, and HRQoL. Repeated-measures multivariate analysis of covariance was used to determine the effects of the teleassistance program. Group × Time interactions revealed significant improvements in the intervention group as compared with the control group for different social cognition's indicators (AR NEPSY-II: p = .003, η2p = .24; TM NEPSY: p < .001, η2p = .35; Verbal task: p < .001, η2p = .35; Happé's Strange Stories: p = .049, η2p = .11) and HRQoL (Psychosocial health: p = .012, η2p = .18; Emotional functioning: p = .037, η2p = 0.13; Social functioning: p = .006, η2p = .21; Total: p = .013, η2p = .17), showing medium to large effects. Patients receiving the neuropsychosocial intervention showed improvements in their social cognition performance and psychosocial HRQoL, providing evidence about the positive effects of the program in pediatric patients with NMD. This should be considered in further research and interventions in this field.

Handling sensory disabilities in a smart society

Billions of people live with visual and/or hearing impairments. Regrettably, their access to systems remains delayed, leaving them socially excluded. The need for universal access of next-generation systems and users’ inclusion is paramount. We pose that a smart society should respond to this crucial need. Following ability-based design principles, we introduce a simulated social robot that adapts to users’ sensory abilities. Its working was assessed via a Rock–Paper–Scissors game in an Intelligent Environment (IE), using three modes: where the user is able to see and hear, only see, or only hear. With this game, two user-studies were conducted using the UMUX-LITE usability score, an expectation rating, and the gap between experience and expectation, complemented with two open questions. A repeated measures Multivariate ANalysis Of VAriance (MANOVA) on the data from study 1 unveiled an overall difference between the three modes, F ( 6 , 6 ) = 6.823, η p 2 = .872, p = .017. Users expected applications to be harder to use with a disability, especially a visual impairment. All modes were considered accessible, with the experience exceeding expectations for the mode with a hearing impairment. In parallel, substantial variance was observed across participants and the results from the open questions suggested improvements. To reduce this variance and increase system stability, study 2 was run with an enhanced design. A repeated measures MANOVA on the data from study 2 confirmed study 1’s findings, F ( 6 , 6 ) = 12.801, η p 2 = .928, p = .003. Moreover, experiences exceeded expectations in all modes and the variance among participants was substantially decreased. We conclude that IE applications managed by a social robot can be adapted to user’s sensory abilities, improving smart society’s accessibility, and, hence, reducing social exclusion.

The effect of incline walking on lower extremity and trunk mechanics in older adults

Older adults are at an increased risk of developing knee osteoarthritis. High internal knee abduction moment during daily activities may elevate the risk of knee osteoarthritis. Incline walking exercise has been found to decrease knee abduction moment in healthy young adults. However, it is unknown if this occurs in healthy older adults. The purpose of this study was to quantify the internal knee abduction moment at different treadmill grades to determine if incline walking could reduce the knee abduction moment in healthy older adults. Twelve healthy older adult males walked on a treadmill at five incline grades (0%, 5%, 10%, 15%, and 20%) at 1.34 ​m⋅s-1. The primary outcome variable was the internal knee abduction moment. A one-way repeated measures multivariate analysis of variance was performed to determine differences in the dependent variables among incline gradients. Peak knee abduction moment significantly decreased from level walking at all gradients in 10% increments (0%–10%, p ​< ​0.001; 5%–15%, p ​< ​0.002; and 10%–20%, p ​= ​0.04). A reduction in knee abduction moment during incline walking could result in decreased knee joint loading on the medial knee compartment. For older adults, who are looking to exercise to improve their health, incline walking may be beneficial to promote lower body strength and cardiovascular ability without inflicting further harm to the aging knee joints. However, because the frontal plane knee joint was of primary interest in this study, further research is needed to determine the effects of incline walking on other joints and in other planes of motion.

Vestibular Function Monitoring in a Pediatric Cochlear Implant Program

Purpose: The purpose of this project was to retrospectively evaluate a vestibular screening protocol and results in children with cochlear implants (CIs) to provide information for other clinics considering implementing similar programs. Method: A retrospective analysis of chart data was completed using descriptive statistics and a repeated measures multivariate analysis of variance design in context with the current state of literature on vestibular monitoring in the pediatric CI population. Results: Pre-CI testing was focused on cervical vestibular evoked myogenic potentials (cVEMPs), which is an efficient and obtainable measure in this population. Postimplantation vestibular testing proved challenging with a high no-show/cancellation rate. For patients evaluated both pre- and postimplantation, there was no significant difference across patients noted; however, individual differences were noted. Conclusions: Vestibular monitoring of pediatric CI patients is important for the overall health and development of this population. An overall assessment of the program and options for continuation of the program considering this analysis are also provided. cVEMP testing is a good option for vestibular monitoring in pediatric CI patients; however, a multifaceted approach is most likely needed to address the many challenges that exist.

Identity Dynamics in Collegiate Olympic Athletes Post-Tokyo 2020: A Pre-Post Study

This study employs a pre-post survey design, engaging a purposive-convenience sample of 94 U.S. college athletes who participated in the Tokyo 2020 Summer Olympics across eight sports and 22 countries. Utilizing validated scales, participants’ group, national, and athletic identities were measured weeks before and after the event. Paired sample t-tests and a repeated measures multivariate analysis of variance were utilized to understand the effects of time and demographic variables on these identities. Results revealed that after competing in the Tokyo 2020 Olympics, college athletes exhibited a significant decrease in their group identity and a significant increase in their national identity, while their athletic identity remained relatively unchanged. The results were qualified by student status interactions such that international students showed a significant decrease in group identity and a significant increase in national identity after competing in Tokyo 2020, with no significant changes observed in these identities for domestic students. The results illuminate a complex process of identity negotiation experienced by collegiate Olympic athletes that transition between Olympic and college sport environments. This study contributes to sport management literature by offering nuanced insights into the dynamics of role-switching, urging stakeholders to utilize these findings to enhance the experiences of college athletes.

MicroRNA-125b Is a Potential Predictor of Surgical Outcomes in Chronic Rhinosinusitis with Nasal Polyps.

Despite advances in surgical techniques, recurrence rates after endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP) remain high and difficult to predict. This study aimed to evaluate the potential role of microRNA 125b (miR-125b) in predicting disease evolution following ESS. We conducted a prospective study including patients undergoing first ESS for CRSwNP in our department between January 2020 and November 2021. We determined miR-125b levels from nasal polyps and pursued a standardized follow-up for at least 18 months for each patient. A total of 86 patients were included in the study. Higher postoperative endoscopy scores were associated with more severe disease at presentation on computed tomography scan, presence of concomitant asthma, and higher values of miR-125b. Even after multivariate repeated measures analysis and adjustments for confounders, miR-125b remained statistically significant. Moreover, miR-125 was the most important factor in predicting disease evolution at 18 months. A clear, robust relation between nasal polyp control evaluated through objective measures and miR-125b values was observed. This finding indicates the potential role of miR-125b in predicting the course of the disease following ESS.

Critical Thinking: A Program Review of Doctor of Audiology Students.

Critical thinking is a crucial component of health care, and its importance has been recognized in training medical professionals. This study reports critical thinking skills for entering doctor of audiology (AuD) students and the trajectory of the change in critical thinking skills measured 2 times over a period of 3 years. This longitudinal, descriptive, and exploratory design was implemented for programmatic review. Critical thinking skills were measured using the Health Sciences Reasoning Test (HSRT; Insight Assessment) upon entering the program and compared to measurements during the final month of academic coursework. Descriptive statistics, exploratory analyses of the HSRT scores among cohorts, the relationship of the HSRT to the graduate record examinations (GREs), and changes in the HSRT over time using a repeated measures multivariate analysis of variance were conducted. There were no significant differences in critical thinking skills between any of the cohort years. There was a significant correlation between the GRE verbal scores and OVERALL HSRT. Improvements in critical thinking skills were found between the time the students entered the graduate program and their final academic semester. Greater gains were reported for students who initially scored below the 50th percentile on the OVERALL HSRT. This program review showed improvement in the critical thinking skills of AuD students during their academic training program. Information regarding critical thinking skills may be useful for programs to monitor students' clinical thinking skills and possibly include clinical and didactical activities to promote critical thinking skills.

It’s all relative: examining the influence of social identity on sport-based youth development

ABSTRACT Social identity theory provides a framework for understanding how identities tied to sport-based youth development programs facilitate positive youth development (PYD). A common assumption guiding youth sport policy and practice is that the social identities formed around sport-based youth development programs are more salient for youth with limited social support, yet this relationship has not been empirically examined. Using a repeated measures research design, the current study examined the influence of program-based social identity on PYD indicators and tested if this association varied across youth with different levels of social support. Latent profile analysis was employed to identify sub-groups based on key social support domains (i.e. family, peers, coaches). The identified subgroups were then integrated into a repeated measures multivariate analysis of covariance, followed up by univariate and regression analyses. Findings reveal that the impact of program-based social identity on the change in PYD indicators was stronger for youth with limited support from family and peers. However, youth with the strongest support in all domains displayed the strongest indicators of PYD over the program season. The results inform a discussion of theoretical implications related to the role of program-based social identity in PYD and highlight managerial recommendations of sport-based youth development program design and management.

Effects of a tailored mat-Pilates exercise program for older adults on pain, functioning, and balance in women with chronic non-specific low back pain: a randomized controlled trial.

Mat-Pilates exercise is effective for chronic non-specific low back pain (NSLBP), but its application in older women is understudied. To examine the effects of a 10-week mat-Pilates program on pain, disability, and balance in older women with chronic NSLBP. Sixty-three women (≥ 65years) with chronic NSLBP were randomly assigned to intervention (IG) or control (CG) groups. IG received individualized mat-Pilates sessions (45min, twice weekly), while CG followed a home-based general exercise program. Primary outcomes included visual analog scale (VAS) for pain, Roland-Morris Disability Questionnaire (RMDQ), timed up-and-go (TUG), and Berg Balance Scale (BBS) at baseline, 10weeks, and 6months post-intervention. Repeated measures multivariate analysis of covariance (MANCOVA) was used, adjusted for exercise adherence and analgesic use. IG significantly improved in VAS and RMDQ scores at 10weeks and 6 months (p > 0.05). No significant differences were observed in TUG and BBS scores at any measurement point. No between-group differences were found in analgesic use or adherence to exercise during the 6-month follow-up. A 10-week mat-Pilates program reduced pain and improved disability in older women with chronic NSLBP, effects which persisted at 6 months. However, no impact on balance, analgesic use, or exercise adherence was observed. NCT04752579/February 12, 2021.

Range of Motion Adaptations During a Simulated Game Exposure in Softball Pitchers.

Hip and shoulder range of motion (ROM) alterations are correlated with increased risk of injury in softball athletes. The purpose of this study was to investigate bilateral shoulder and hip ROM adaptation during a simulated softball double-header exposure. It was hypothesized that shoulder and hip ROM would decrease after simulated game exposure and would not return to baseline following a 30-minute break. Thirty (14.8±1.9 yrs, 162.5±18.3 cm, 71.79±16.03 kg) adolescent softball pitchers participated. Testing included: bilateral hip and shoulder ROM (preSG), simulated game exposure (100 pitches), bilateral hip and shoulder ROM (postSG), 30-minute break, bilateral hip and shoulder ROM (preDH), pitching first inning of a simulated double header (12 pitches), and bilateral hip and shoulder ROM (postDH). Two separate repeated measures multivariate analyses of variance tests determined differences in ROM between time points. Dominant shoulder internal rotation ROM and non-dominant shoulder internal and external rotation ROM significantly decreased from preDG. Stride hip external rotation ROM and drive hip internal and external rotation ROM significantly decreased from preSG to preDH. Key results revealed the break given between games may not be sufficient recovery time for hip ROM. Thus, assessing ROM as workload progresses can be a useful strategy for monitoring a softball pitcher's injury risk.
