Acute Effect of Video Feedback on Self-Regulation and Proprioceptive Control of Standing Back Tuck Somersault in the Absence of Vision.

The purpose of this study was to assess the immediate effect of video feedback on the regulation and control of the standing back tuck somersault in the absence of vision. Two groups of male parkour athletes performed the standing back tuck somersault under both open and closed eyes conditions. The first group received video feedback, while the second group received verbal feedback. Concurrent analysis, including kinetic data from a force plate (Kistler Quattro-Jump) and kinematic data in two-dimensional by Kinovea freeware, was employed for motion and technical performance analysis. The results indicate that the loss of vision during the standing back tuck somersault affected only the take-off and ungrouping angle, as well as the vertical velocity and displacement. These effects were consistent regardless of the type of feedback provided (i.e.,video feedback or verbal feedback). Furthermore, a significant Vision × Feedback interaction was observed at the level of technical performance. This suggests that the use of video feedback enabled the parkour athletes to maintain a high level of technical performance both with and without vision (i.e.,13.56 vs. 13.00 points, respectively, p > .05 and d = 2.233). However, the verbal feedback group technical performance declined significantly under the no-vision condition compared with the vision condition (13.14 vs. 10.25 points, respectively, with and without vision, p < .001 and d = 2.382). We concluded that when the movement is proprioceptively controlled (i.e.,without vision), the video feedback enables the athletes to globally assess the technical deficiencies arising from the lack of vision and to correct them. These findings are discussed based on parkour athletes' ability to evaluate the kinematic parameters of the movement.

Greater Psychophysiological Intensities in Conditioned Games May Impair Technical Performance: An Exploratory Study in Youth Male Soccer Players.

The aim of this study was 2-fold: (1)to examine the relationships between psychophysiological responses and locomotor demands with variations in technical performance during 2v2 and 4v4 conditioned games and (2)to compare psychophysiological and locomotor responses among players exhibiting higher and lower technical performance levels during the conditioned games. Twenty-four male youth soccer players (16.3 ± 0.8y old) participating at the trained/developmental level underwent monitoring for psychophysiological responses (including heart rate, rating of perceived exertion, and visual analog scale), locomotor demands (such as distance covered), and technical performance variables (including successful and unsuccessful passes and shots, as well as lost balls) across 2v2 and 4v4 formats. These formats were applied 4 times within a single session and were replicated twice over 2weeks. Large correlations between the number of lost balls per minute and mean heart rate were found in both the 2v2 and 4v4 games (r = .586 and r = .665, respectively). Successful shots were inversely and largely correlated with mean heart rate (r = -.518) in 4v4 games. The number of interceptions per minute was inversely and significantly correlated with the visual analog scale in 2v2 and 4v4 games (r = -.455 and r = -.710, respectively). The frequency of lost balls was significantly higher among players who attained a higher mean heart rate (2v2: +42.9%, P = .031, d = -0.965; 4v4: +57.1%, P < .001, d = -2.072). Coaches should be aware that highly psychophysiologically demanding scenarios may significantly impair technical performance. Therefore, prioritizing technical performance by deliberately adjusting the intensity should be considered.

Predicting the level of technical performance by indicating the Hook (side punch) and, the blasting power of arms as the basis of selecting juniors in boxing

&#x0D; The problem of the research is lurking in informing the researchers and their inquiries about the function of the coaches in the institutions that are specialized in preparing and developing the junior players and the modest experience of researchers. They observed a phenomenon lying in the randomness of coaches in picking their players depending on subjective judgments and lack of using objective tests, in the addition to the rarity of studies that pertain to predicting this age groups in terms of physical and skill indicators which do not determine the suitable standards for their age level. The research aimed to identify the level of the Hook (side punch) performance and the blasting power of arms for the junior players and finding the correlational between the Hook (side punch) test and the blasting power of arms and finding scales (grades and levels) for the used tests and deriving predictive formula for the technical performance by indicating the Hook (side punch) and, the blasting power of arms as the basis of selecting juniors in boxing .The researchers assumed that there is a correlation between the Hook (side punch) test and the blasting power of arms, they used the descriptive method due to its relevance to the nature of the problem, the researchers identified the research population by using the purposive method which are the junior sixteen players of Hilla sport club .The research sample had been selected in the random method which are fourteen players formed 87.5% percentage from the original research population .The researchers used a set of tests for blasting power and technical performance of the Hook (side punch) skill when they concluded :Researchers found the measurement of the Hook (side punch) and the blasting power of the arms for the junior players of boxing.Calibers had been found (grades and levels for the used tests).Correlations and predicting formulas had been found for technical performance level.The researchers recommended the following 1-Coaches and experts should concentrate on the blasting power of arms in selecting talented juniors in boxing.2- Coaches should pay attention to the mechanism of selecting and choosing talented players in the other sports in term of focusing on the main characteristic of the game.3-Doing other studies and researches care about perfect mechanism in selecting talented players of different sports.&#x0D; &#x0D; &#x0D;

The Effect of The Strength of The Center Muscles on Improving the Level of Technical Performance of Some Stability Movements on the Mat of Floor Movements

The purpose of this research was to determine whether some stability exercises performed on the floor exercise mat to increase core strength would improve the technical application level of students. Method: A sample of 39 young male students from a university (age = 22.1±1.2 years, height = 170.3±6.5 cm, weight 65.2±8.7 kg, Body Mass Index = 22.5±2.8) participated in the study. The participants were into the control group (n=19) and experimental group (n=20) completed pre-tests and post-tests. The CS was assessed by the Stability Movement Push-ups, Abdominals, Back, Pull-ups, Headstand. The results of the paired samples t-tests show that the experimental group had a significant improvement in the mean scores for all four movements on the post-test compared to the pre-test. The mean score for the push-ups increased from 4.9±1.2 to 7.5±1.3 (t(14)=-10.78, p&amp;lt;0.001), the mean score for the abdominals and headstand increased from 4.6±1.0 to 7.0±1.2 (t(14)=-10.14, p&amp;lt;0.001), the mean score for the back and handstand increased from 4.8±1.1 to 6.9±1.2 (t(14)=-7.86, p&amp;lt;0.001), and the mean score for the pull-ups increased from 4.7±1.0 to 7.3±1.1 (t(14)=-11.47, p&amp;lt;0.001). Since the p values of the four movements are lower than 0.001, it is seen that there is a statistically significant difference between the scores obtained in the pre-test and the scores obtained in the post-test. According to the results, working out the core muscles may help enhance the technical execution of stability exercises performed on the mat or floor.

MICROLENS - A DESIGN-CENTRED APPROACH TO AI IN HEALTHCARE

Abstract AIMS MicroLens aims to co-develop tools and functions that enable patients &amp; caregivers to view and understand their own images. METHOD We used an explicit design-led approach, foregrounding user needs. Over 7 months we used a series of 4 meetings, written reports and online questionnaires capturing the views of 20 staff, patient and caregiver participants (55% patients &amp; caregivers; primary &amp; metastatic brain tumours) to explore feasibility and requirements for an AI-enhanced online medical image viewing tool. RESULTS There were two distinct patterns of preferred usage: smartphone-based “snapshot” approach vs. online plat- form with detailed review of all images. Participants wanted to use it as a “scan photo album” and said help in understanding the scans would be useful, but the desired level of technical performance was relatively low: patients and caregivers would mostly be happy with labelling of common simple structures and sides, rather than detailed annotation. Further benefits and concerns raised were ability to • share with family members who could not attend hospital appointments. • review their scans outside of an appointment. • better understand images. • Use tools to assist in the interpretation reducing staff workload • image-share causing more work for staff CONCLUSIONS Patients, caregivers and staff all expressed a clear view that an AI-enhanced online tool to allow patients to view and understand their images would be useful. However, there were significantly different use cases between different patients, and the level of functionality that patients &amp; caregivers expressed a need for was substantially simpler than that originally envisaged. We are currently implementing a prototype.

OS05.7.A MICROLENS: EXPLORING THE GAP BETWEEN PATIENT AND CAREGIVER NEEDS, AND TECHNICAL DEVELOPMENTS IN AI-ENABLED MEDICAL IMAGE INTERPRETATION

Abstract BACKGROUND MicroLens aims to co-develop tools and functionality to enable patients &amp; caregivers to view and understand their own brain tumour images, using an explicit design-led approach. Over 7 months we used meetings, written reports and online questionnaires to capture the views of 20 staff, patient and caregiver participants requirements for an AI-enhanced online medical image viewing tool. We have described our initial approach and results (1), but here we focus on how patient and caregiver needs differ from technological approaches described in the medical imaging literature. MATERIAL AND METHODS As part of the MicroLens project, we used thematic analysis to extract key patient, caregiver and staff concerns and needs. We then compared this with technical themes of the medical imaging technical literature, drawn from conference proceedings (MICCAI). RESULTS The desired level of technical performance was relatively low: patients and caregivers would mostly be happy with labelling of common simple structures and sides, rather than detailed annotation. Other desirable functionality was around sharing imaging with family members and better understanding of imaging. In contrast, the technical literature had a focus on tumour segmentation, classification and prediction of outcomes - none of which appeared in patients' desiderata. CONCLUSION Patients, caregivers and staff want very different functionality than the work being conducted in the technical literature. The reasons for this are interesting, and multi-factorial, but reinforce the need for patient-led development. We are currently implementing a prototype and our software developers are designing and developing five of the key tools that emerged from MicroLens project, based on a combination of our findings and theoretical approaches such as the NASSS framework (2).

Psychological recreation of overcoming failures and achieving success by young rhythmic gymnasts aged 6-8

Background and Study Aim. Performing physical exercises in rhythmic gymnastics requires not only physical ability, but also psychological stability and a suitable recreational environment. The satisfaction of doing gymnastic exercises is an important component of children's success. The aim of this study: to investigate the impact of psychological means of motivation and recreation, including intrinsic and extrinsic factors, on the performance and success of young gymnasts aged 6-8 in rhythmic gymnastics exercises.&#x0D; Materials and Methods. A total of 20 girls (employment experience - 2-4 years) aged between 6 and 8 years who were engaged in rhythmic gymnastics at Sports school No. 5 (Kharkiv, Ukraine), participated in this study. The participants were divided into two groups - experimental and control, based on their technical training levels determined by the results of the competition. Each group comprised 10 gymnasts. The research utilized two sets of tests: 1) psychological tests to assess the motivational sphere of gymnasts, including the Sports Motivation Scale and the State-Trait Anxiety Inventory for Children; 2) technical training tests, specifically exercises with a hoop. The technical tests were scored by two experienced coaches on a 10-point scale.&#x0D; Results. The results of the study showed that the use of psychological training in the training process increased the level of motivation to achieve success. The motivational component of training was found to be closely related to the creation of an appropriate recreational environment, which in turn affected the level of technical performance of "risk" elements with the object among young gymnasts.&#x0D; Conclusions. The introduction of techniques and means of psychological preparation for performing complex throwing exercises with objects had a positive effect on increasing the level of motivation to achieve success and overcome failures. This approach helped to improve results when performing complex "risk" elements. The findings suggest that incorporating psychological means of recreation in training programs for young gymnasts can be beneficial for their overall performance and success.

Homogeneity in Surgical Series: Image Reporting to Improve Evidence.

Good clinical practice guidelines are based on randomized controlled trials or clinical series; however, technical performance bias among surgical trials is under-assessed. The heterogeneity of technical performance within different treatment groups diminishes the level of evidence. Surgeon variability with different levels of experience-technical performance levels even after certification-influences surgical outcomes, especially in complex procedures. Technical performance quality correlates with the outcomes and costs and should be measured by image or video-photographic documentation of the surgeon's view field during the procedures. Such consecutive, completely documented, unedited observational data-in the form of intra-operative images and a complete set of eventual radiological images-improve the surgical series' homogeneity. Thereby, they might reflect reality and contribute towards making necessary changes for evidence-based surgery.

In-service training policy during the COVID-19 pandemic: The case of the agents of the farmers, rural people, and nomads social insurance fund.

The COVID-19 pandemic has posed the in-service training of agents of the Farmers, Rural People, Nomads Social Insurance Fund (hereafter the Fund) to many problems. In-service training is one of the most effective development factors for organizational goals. This sort of training will increase employees' skills and subsequently improve their job performance. Accordingly, the present research mainly aimed to shed light on the effect of in-service training policy on employees' capabilities and job performance. The research was conducted among the agents of the Fund in Fars province, Iran (N = 197) out of whom 127 agents were sampled by simple randomization. The research instrument was a standard questionnaire whose face and content validity was confirmed by a panel of experts and its reliability was determined by calculating Cronbach's alpha in a pilot study. The results showed that the indicators used to measure the research variables were acceptably consistent with the factor structure and the theoretical framework of the research. Based on the findings, in-service training in the Fund during the COVID-19 pandemic has had a positive and significant effect on the agents' capabilities (communication and team-working skills, creativity and problem-solving skills, commitment and responsibility, technical information and knowledge, and technical and practical skills) and job performance at the individual, technical, and general levels. Also, the agents' capabilities have had a positive and significant influence on their job performance. It can be concluded that in-service training can influence the agents' capabilities and job performance and improve organizational performance during the COVID-19 pandemic. Thus, the enhancement of in-service training courses' quantity and quality during the COVID-19 pandemic can influence the job performance of the agents at the individual, general, and technical performance levels.

Applying exercises according to the mass moment of inertia and its impact on some types of strength and achievement for long jumpers

Remarkable scientific progress in the field of jumping, especially in recent years, was touched upon, and the focus was on training by changing the positions of the body and its parts during flight in the broad jump, as the researcher believes that the use of this method may affect the development of the special strength of the players in the broad jump, which is reflected On the development of the level of the stages of the performance of the broad jump on the development of the special character of the players, and the effectiveness of the broad jump is one of the athletics activities that depend directly on strength and speed at the same time, and the researcher dealt with the aspect of strength by changing the position of the player's body in order to achieve the integrated conditions for performance that will inevitably enhance the achievement What is good for him is that strength training by changing the position of the body and overcoming resistance by using auxiliary means, means that have not been confirmed according to the mechanical principles in the field of training for broad jump players in strength training in athletics, so the researcher believes that this topic is a scientific problem that can be addressed and studied. The aim of the research is to identify the impact of training according to this method in the positive development of the value of the moment of inertia for each stage of the broad jump, and the research hypothesized that there are statistically significant differences between the pre and post-tests in the value of the moment of inertia for each stage of the broad jump in the two research groups, which included This section presents the results that were reached from the pre and post tests, which were applied to the research sample, and scientific results were reached and then discussed. The level of technical performance (technique) developed in the experimental group in the post tests after using the exercises, which indicated the effectiveness of these exercises. In achieving a good level of motor cohesion, no improvement was shown in the technical level in the control group. The conclusions of the research came, and this means the effectiveness of the impact of exercises according to the principle of the body's moment of inertia in the development of transport between the different parts of the body.

The effect of special exercises in developing the values of some bio kinematics variables and physical abilities of the accuracy of the crushing transmission skill in volleyball (Misan players 20-25 years old)
