Overarm Throwing

Throw accuracy is not being currently quite developed within school PE lessons; it is being developed only as part of skills of a particular sports discipline. Th is shortcoming may stem from the lack of a suitable test assessing this skill. In the literature we have seen only three throw accuracy tests intended for school youngsters (Bös 2001, Mecner 1975, Měkota; Blahuš 1983). Th ese tests consist of a few repeated series of throws, failing to distinguish a throwing distance for boys and girls and even age groups, and requiring a rather complicated graphic record of successful target hits that cannot be assessed easily and quickly during a PE lesson. Th e purpose of the study is to create a test of measuring throw accuracy at a target eliminating the aforementioned shortcomings. Th e optimisation of a throwing distance is based on the condition of a normal Gaussian distribution of data related to individual throwing distances, and on the condition that an average number of target hits within a concrete throwing distance will be close to 7.5 target hits. To assess the importance of the diff erence of the observed throwing distances one-factor ANOVA (One Way Analysis of Variance) was used. Th e assessed group consisted of 105 boys and 114 girls of three randomly selected schools in Ostrava between 11 and 14 years old. Th ree throwing distances were determined (boys 6; 8; 10 m, girls 3.5; 5.5; 7.5 m) in combination with a vertical round target of 0.7 m in diameter. Th e tested person used an overarm throwing technique and made 20 throws for each throwing distance. Th e test score was the number of the target hits from the 6th - 20th throw (training: 1st -5th throw). Th e optimum throwing distances were identifi ed for the accuracy test of a target throw for boys of the 11-12 year category (6 m), 13-14 year category (8 m), for girls of the 11-12 year category (5.5 m), 13-14 year category (7.5 m) while using a target of 0.7 m in diameter.

Venous Disorders

Background The prevalence and presentation patterns in women with pelvic venous disorders (PeVD) secondary to pelvic venous insufficiency (PVI) at various ages are ill-defined. The purpose of this investigation was to determine if the types of symptoms, interventions, and treatment outcomes of women with PeVD varied with age progression. Methods From January 2015 to December 2019, we retrospectively reviewed prospectively collected data on 1,280 women with PeVD from our electronic medical record at the Center for Vascular Medicine (CVM). Medical and surgical comorbidities, past medical history, presenting pelvic and lower extremity symptoms, Clinical, Etiology, Anatomy, Pathophysiology (CEAP) class, revised Venous Clinical Severity Score (rVCSS), visual analog pain score (VAS) and types of interventions were assessed. Patients were grouped into five categories based on age of initial presentation: 20–29, 30–39, 40–49, 50–59, and greater than or equal to 60. Patients were also subcategorized according to their course of treatment: Iliac venous stenting alone, ovarian vein embolization (OVE) alone, simultaneous iliac vein stenting and ovarian vein embolization, and staged iliac vein stenting and ovarian vein embolization. Differences in groups were analyzed utilizing chi square, analysis of variance and regression analysis with Graphpad Prism 8 (San Diego, CA) and SAS Studio 3.8 (Cary, NC) statistical software. Results From January 2015 through December 2019, 1,280 women were treated for PeVD. The average ages in each group were the following: 26.53 ± 2.90 (n = 57), 35.80 ± 2.84 (n = 238), 44.98 ± 2.78 (n = 345), 54.67 ± 2.90 (n = 324) and 68.39 ± 8.44 (n = 316) respectively. The prevalence of PVI by age group was 4.45%,18.59%, 26.95%, 25.31% and 24.70% respectively (p < 0.05). The prevalence of diabetes, hypertension, coronary artery disease (CAD) and hypercholesterolemia differed between age groups (p < 0.05). Significant differences in the prevalence of pelvic pain, dyspareunia, dysmenorrhea, vulvar varices, leg pain, leg edema, leg heaviness, restless legs, varicose veins, and leg ulcers were observed across treatment groups (p < 0.05). CEAP distribution differed by age with CEAP 0–2 decreasing with age, CEAP 3 progressively increasing with age and CEAP 4–6 predominantly observed in patients older than 50. Analysis of variance indicated that with each decile increase in age, the prevalence of leg symptoms increased (p < 0.05) with a reciprocal decrease in pelvic symptoms (p < 0.05). All intervention types were infrequent in twenty year old’s. There was a linear increase in stenting with each decile increase in age. The prevalence of OVE was similar across all age groups. There was an overall improvement in VAS scores for all treatment and age groups. For patients in their 20 s, an initial improvement in VAS scores was observed with moderate recurrence of pain observed after three months. Conclusion PeVD presents as a spectrum of signs and symptoms, with pelvic and leg symptoms being inversely related according to age. The prevalence of PeVD is lowest in patients in their twenties with differences in presentation observed with increasing age. Venous stenting progressively increases with each decile of age whereas the prevalence of OVE is similar regardless of age. There is overall improvement in symptoms post intervention, although women in their 20 s do not respond as well to intervention as women in other age groups. Future investigations will focus on determining which pelvic venous lesion is the predominant factor that needs correction to achieve maximal pain reduction.

Representational momentum (RM) is the phenomenon that occurs when an object moves and then disappears, and the recalled final position of the object shifts in the direction of its motion. Some previous findings indicate that the magnitude of RM in early childhood is comparable to that in adulthood, whereas other findings suggest that the magnitude of RM is significantly greater in childhood than in adulthood. We examined whether the inconsistencies between previous studies could be explained by differences in the experimental tasks used in these studies. Futterweit and Beilin used a same-different judgment between the position where a moving stimulus disappeared and where a comparison stimulus reappeared (judging task), whereas Hubbard et al. used a task wherein a computer mouse cursor pointed to the position where the moving stimulus disappeared (pointing task). Three age groups ( M = 7.4, 10.7, and 22.1 years, respectively) participated in both the judging and pointing tasks in the current study. A multivariate analysis of variance with the magnitudes of RM in each task as dependent variables revealed a significant main effect for age. A one-way analysis of variance performed for each of the judging and pointing tasks also indicated a significant main effect of age. However, post hoc multiple comparisons detected a significant age effect only for the pointing task. The inconsistency between the judging and pointing tasks was discussed related to the distinct effect size of the age difference in the magnitude of RM between the two tasks.

Abstract Background: Elaborated system of neuromuscular connections gives to a human ability of body control, possibility to move and perform any complicated moves. The issue of neuromuscular conduction appears more frequently in physiotherapy, biological restoration or, widely perceived, sport training. Physiotherapists often wonder how sauna treatment, mainly used in biological restoration, influence on changes of its conduction and, on which level of a rehabilitation, training process or biological restoration should it be used. The aim of this paper was to check how an organism would react after methodically conducted sauna treatments in a form of whole body biological restoration. Material/Methods: Competitors of cycling group GR AIRCO Team participated in research. Twelve men were classified and divided onto two age groups. On the basis of questionnaires personal details as well as basic antropometric parameters were collected. Tool used to measure reactivity was chosen to research method: Reactivity Measure MCZR/ATB 1.0. Results: Analysis of variance of following measurements did not show any statistically crucial differences between the group under the age of 30 and over 30 (p>0,05). Results are shown respectively for right leg, left leg, both lower limbs tested simultaneously with the division onto age groups. Analysis of variance show increase of reactivity for all tested participants after sauna. Conclusions: Sauna treatment among cyclist has impact on a rate of lower limbs reactivity tested simultaneously with impulse differentiation to an appropriate legs.

9 expressive body gestures were recorded while 180 boys and girls of three age groups (4—5 yr., 7—8 yr., and 10—11 yr.) individually performed a standardized play task. Analysis of variance showed a significant over-all difference in gestures between the sexes, and 5 of the gestures (“limp wrist,” “arm flutters,” “flexed elbow,” “hand clasp,” and “palming”) occurred significantly more frequently in girls than boys. There was an interaction between sex and age for the “hands-on-hips with fingers forward” gesture. No differences associated with sex of experimenter were found.

Divergent selection for fecundity in a South Australian Merino flock was carried out over a 10 year period at Roseworthy Agricultural College, South Australia. Comparisons were made between two flocks of sheep in which selection was restricted to ram replacements. Analyses showed that very little response was achieved. Pooled estimates of repeatability by analysis of variance were 0.04 for lambs born per ewe joined (LBJ) and 0.14 for lambs born per ewe lambing (LBP). Pooled half-sib estimates of heritability were 0,10 for LBJ and 0.10 for LBP. The realized heritability of LBP was 0.03, averaged over age groups. The lack of response was due to limited selection pressure and the time taken for improvement to pass through the breeding flock.

This study investigated infant listening preferences for two versions of an unfamiliar Chinese children's song: unaccompanied (i.e., voice only) and accompanied (i.e., voice and instrumental accompaniment). Three groups of 5-, 8- and 11-month-old infants were tested using the Headturn Preference Procedure. A general linear model analysis of variance was carried out with gender and age as the between-subjects variables and listening time to the two renditions (unaccompanied, accompanied) as the within-subjects variable. Results indicated a clear preference for the unaccompanied version of the song in all age groups.

The purpose of this study was to identify learning transfer variables impacting on learning transfer using the Learning Transfer System Inventory (LTSI). The secondary objective was to determine if there are any statistically significant differences in the mean transfer variable scores between geographical areas, years of service, age groups, sex, qualifications and language groups. The sample used in this study was a convenience sample of 240 employees working for a Banking group. Analysis of variance (ANOVA), Multivariate analysis of variance (MANOVA) and posthoc tests were used to analyse the data. The results show that, while age and gender do not have an impact on the learning transfer factors, level of education, home language and both length of service within the organisation and in the current position do. Geographic area also impacts on learning transfer indicators. Effect sizes, however, are small to moderate

The Impact

Abstract Purpose The ImPACT™ Quick Test (QT) is a brief iPad-based battery of neurocognitive tests that has been standardized on a sample of children, adolescents, and adults (ages 12-70). We sought to provide information regarding the prevalence of low ImPACT™ QT scores in the normative sample to improve clinical interpretation and reduce the risk of over-interpreting, or misinterpreting, a single low score. Methods Participants included 616 individuals ranging in age from 12 to 70, who were assessed individually. The ImPACT QT includes five subtests, contributing to three factor scores: Motor Speed, Memory, and Attention Tracker. The prevalence of low factor scores, stratified by age and gender, were calculated using multivariate base rates. Results In the total sample, obtaining 1 score below the 25th percentile was common (base rate, BR=31.8%), but obtaining 2 or more scores in this range was uncommon (BR=13.3%). Similarly, obtaining 1 score below the 16th percentile was common (BR=22.3%), but obtaining two or more scores in this range was very uncommon (BR=5.4%). There were small differences in base rate between genders and the number of low scores were fairly similar across the age groups. Conclusion Results from this study parallel previous work illustrating that a substantial percentage of healthy individuals will obtain one or more low test score when administered a battery of multiple cognitive test measures. Given that some healthy, non-concussed individuals will obtain a single score below expected cut-offs, clinicians should caution against overinterpreting a single low test score.

15 boys in each of three age groups were tested for ability to reproduce learned linear arm-positioning movements using a slide bar. Movements of 10, 20, and 40 cm were learned without the aid of vision by moving the slide to a stop, then repeated from the same starting position without the stop in place. Analysis of variance yielded a significant main effect of length of movement for both absolute and constant error and also a significant interaction between age and length of movement. The discussion offers explanations based on information-processing capacity and patterns of child development.

Primary Pupils

Currently, research on possible psychological and socio-psychological problems of children and adolescents during the period of their education is becoming increasingly important. Extensive use of short screening tests-questionnaires allows to identify possible deviations in the psychosocial functioning of ordinary children and adolescents, children with somatic diseases, victims of violence. The aim of the study was to increase the effectiveness of determining psychosocial dysfunction in children of primary school age by analyzing the results of a screening study. Using «Pediatric Symptom Checklist» methodology, including child (Y-PSC) and parent (PSC) versions in Ukrainian adaptation, 263 primary schoolchildren and 228 parents were examined by filling out a paper version or an online version. Statistical processing of the data was performed using t-test and one-way analysis of variance in a licensed SPSS Statistic v.20 software suite. With the help of adapted version of the methodology, it was determined that general average level of psychosocial functioning of primary pupils, according to Y-PSC, was exceeding the established norm, particularly during 2nd and 3rd study years; this fact can be the evidence of some stress in mechanisms of psychosocial adaptation during that period. According to the child version, critically high indicators were observed in 12.9% of cases – by attention subscale, in 33.1% – by internalization subscale, in 21.7% – by externalization subscale. According to parent version (PSC), critically high indicators were observed in 18.9% of cases – by attention subscale, in 7.9% – by internalization subscale, and in 32.9% – by externalization subscale. By one-way analysis of variance, it has been established that psychosocial state is affected by sex, grade and method of survey. For example, attention and externalization subscale indicators were higher in online data. In girls, there was a higher level of internalization, while in boys, veraciously – of externalization, according to both parent and child versions. Indicators by attention and externalization subscale have been significantly higher in first-graders, while the level of internalization – in students of 2nd and 3rd grade. Therefore, obtained results can be utilized as groundwork for further study of various age groups of schoolchildren and adolescents. Additionally, dynamic observation of risk group children while employing psychologists, primarily school psychologists, for support, psychological interventions, and psychoeducational programs, can produce certain reasonable activities for overcoming and deactualization of present deviations at a prenosological level.
