AimWhile there are several conservative therapy methods used for patients with chronic low back pain (CLBP), there remains a need for more holistic approaches. This pilot study was designed to evaluate the effectiveness of Basic Body Awareness Therapy (BBAT) in patients with CLBP.MethodsTwenty-eight patients with CLBP, 14 in the Conventional Therapy (CT) group and 14 in the BBAT group, were included in our study. Both groups received CT for 6 weeks, which included electrotherapy, hot pack, and general exercises. The BBAT group received BBAT in addition to CT. The Short Form McGill Pain Questionnaire (SF-MPQ) was used to assess pain, the SF-12 was used to evaluate quality of life and the Awareness Body Chart (ABC), Body Awareness Questionnaire (BAQ) and Fremantle Back Awareness Questionnaires (FreBAQ) were used to evaluate body awareness. Oswestry Disability Index (ODI) and Physical Impairment Index were used to assess disability.ResultsGreater improvements were observed in BBAT group compared to CT group in the emotional index and total scores of the SF-MPQ, as well as the SF-12 mental health scores (p < .05). BBAT produced greater improvements in body awareness values for the cervical-lumbar region, chest/abdomen, back, shoulder, thigh/hip, lower leg, and overall score of the ABC compared to CT (p < .05). However, there were no significant differences between the groups in the FreBAQ and BAQ scores (p > .05).ConclusionIn patients with CLBP, the addition of BBAT to CT resulted in positive outcomes such as increased body awareness, decreased pain, and improved mental health.

In the present investigation, we used structural equation modeling with 251 adolescents to reveal, through path analyses, the degree to which somatization might mediate the relationships between body image and self-harming behaviors. After controlling for the effects of (a) age, (b) gender, and (c) having previously visited a psychologist, we observed that somatization fully mediated both the relationship between body image and self-harming behaviors and the relationship between gender and self-harming behaviors. These results suggest that having a less satisfied relationship with the body or a more negative body image is closely related to a somatic experience of greater psychological suffering, which could lead, in turn, to a more active expression of this suffering through self-harming behaviors.

Symptoms of "the yips" manifest in various sports and often cause athletes to retire prematurely from competition. While there have been case studies on yips-affected baseballers (YBBs), there has been no comprehensive demographic profile of YBBs, and contributing factors are only partially understood. We aimed to describe youth YBBs' demographic characteristics and explore contributing factors to yips symptoms. We analyzed a self-report questionnaire administered to 285 youth baseballers to investigate yips symptoms and identify both players' psychological characteristics and trigger factors for yips. We defined YBBs as players who exhibited symptoms of involuntary muscle contractions, characterized by jerks, tremors, or freezing during planned movements that resulted in unpredictability when throwing a baseball. Individuals without these symptoms were categorized as non-yips-affected baseballers (NBBs). In our total sample, there was a YBB prevalence of 10.2% with a significantly higher occurrence among pitchers than among players in other positions (p < .05). Additionally, YBBs showed a significantly higher incidence of self-reported anxiety during throwing compared to NBBs (p < .001), and a significantly greater proportion of YBBs than NBBs struggled particularly with gentle or light motion throws (p < .001), especially at short distances (75.0% of the YBBs). Furthermore, 62.1% of YBBs faced difficulties in appropriately releasing the ball. Thus, we found approximately one in 10 youth baseballers experienced yips symptoms that were influenced by throwing distance and high-pressure situations. Our descriptive study advances an understanding of yips-related performance problems in youth baseballers.

The L Test has been developed to assess balance and gait disorders. Our aim in this study was to estimate the test-retest reliability and validity of the L Test when used with 82 persons with multiple sclerosis (PwMS). For these participants, we examined the degree of agreement between the results of a first and second administration of the L Test (separated by one day), using Bland-Altman analysis and intra-class correlation coefficients (ICCs). We computed minimal detectable change (MDC) and standard error of measurement (SEM) values for the L Test and evaluated concurrent validity by correlating L Test results with the Timed Up and Go test (TUG) and the 10-minute Walk Test (10MWT). Prior to administering these measurements, we randomized the sequence of the test administrations to our participants. The Bland-Altman analysis showed that L Test was reproducible, with upper and lower limits of agreement of 0.99 and -1.45 seconds, respectively. The L Test demonstrated excellent test-retest reliability, with an ICC value of 0.996 (95% CI: 0.994-0.998). Cronbach's alpha coefficient was 0.996. The performance of the L Test is measured by seconds required to complete the task, and we found the L Test SEM value to be 0.35 seconds, and its MDC value to be 0.97 seconds. The L Test showed a strong correlation with both the TUG test (rho = 0.936; p < .001) and the 10MWT (rho = 0.925; p < .001). We concluded that the L Test is a reliable and valid tool for assessing functional mobility and balance in PwMS.

Relative Age Effects (RAEs) have been widely reported trends in basketball participation, but research on the relationship between RAEs and competitive performance has been contradictory. We aimed to determine the magnitude of RAEs in elite youth basketball players and to analyze RAEs on key performance indicators (KPIs). We recorded and analyzed the incidence of early birthdates and the KPIs of 2487 youth basketball players (aged 16-19 years). We evaluated RAEs by means of the incidence of early birthdates using (i) Chi-square (χ²) goodness-of-fit tests to compare player differences in birthdate quartiles and (ii) Poisson regression analysis to evaluate birthdates as a continuous variable. We conducted Kruskal-Wallis tests separately for each age group to assess possible relationships between birthdate quartile differences and KPIs. We observed consistent moderate RAEs across all ages. The Poisson regression analysis showed that athletes born near the beginning of the year were 4.6-8.4 times more likely to have been included on the squad than athletes born towards the end of the year. We observed no significant differences between KPIs for differently aged athletes. However, 16-year-old athletes with first quartile birthdates showed higher KPIs than those with fourth quartile birthdates of the same calendar year. The potential bases for RAEs are complex and include the characteristic demands of sports competition at various competition levels and athletes' ages, individual factors and social factors. We discuss these and other potential bases. Basketball coaches and managers should keep RAEs in mind when selecting youth players to avoid a selection bias towards players born at the beginning of the year which may close out training opportunities and cause drop outs for talented but slightly younger players.

The 8-item Passion Scale (PS-8) is a unidimensional instrument used in dual versus single passion research. The PS-8 was validated in Icelandic, Persian, and Turkish student samples. In this study, we translated the PS-8 and validated it with physically active and inactive adults from Hungary. We also evaluated measurement invariance (across gender, physical activity, exercise frequency, and age groups) of the Hungarian version of the Passion scale (PS-8-HU). Data were collected online between fall 2023 and winter 2024, including a test and retest phase. The sample comprised 729 Hungarian physically active and inactive adults (68% females, 32% males; ages 18-78 years), of whom 196 participated in the retest. We used confirmatory factor analysis (CFA), item analysis, correlations, t-test and ANOVA in checking the scale's validity and reliability, and we used a multigroup CFA to test the measurement invariance. The results supperted a univariate structure of the PS-8-HU. The instrument was invariant for gender (at the strict level), exercise frequency (metric), physical activity (metric), and age (scalar). The internal reliability of the PS-8-HU was .93 and test-retest reliability was .77. The PS-8-HU also exhibited good concurrent and construct validities, high homogeneity, and adequate discriminant validity.

In this study, we expanded on previous research by employing a Multiple Indicators, Multiple Independent Causes (MIMIC) model to investigate how gender, age, body mass index (BMI), and perceived stress may have collectively influenced social physique anxiety (SPA) among 593 college kinesiology students. Our MIMIC model revealed that perceived stress, gender, and BMI were significantly related to SPA scores, with perceived stress being the strongest factor. Moreover, the relationship between gender and kinesiology students' SPA scores was consistent across different ages. These findings broaden the spectrum of the current nomological network regarding predictors of SPA. Based on these findings, future researchers should extend the current MIMIC model by including more predictor variables (e.g., depression, mood, & mental toughness) to gain additional and perhaps deeper insights. Additionally, we advocate for the adoption of the MIMIC model of statistical analysis in future SPA research.

The way a map scale is represented plays a key role in comprehending it. In this research, we examined the relationships between the form of representation of the map's scale (numerical scale, linear graphic scale and circular graphic scale), the user's gender, and the distance between two map objects on user estimates of the distance between two objects on the map (i.e., a 5, 10, 15 and 20-min walk). We gave 183 college students 84 maps of three types: 28 numerical scale, 28 linear graphic scale, and 28 circular graphic scale. Each map presented varied distances to be estimated. We assessed the participants' accurate hits, errors, and their hits minus errors in these distance estimations. Participants had both more hits and more errors on circular scale maps than on linear or numerical scale maps, and the distances between objects and gender also significantly related to the estimated e distance. Both the type of scale and the distance between objects influenced the number of hits minus the number of errors.
