Inhabiting the Body(ies) in Female Soccer Players: The Protective Role of Positive Body Image

In a social and sports world dominated by weight-centred beliefs and highly exigent and gendered athletic and beauty body standards, the vulnerability for eating pathology, i.e., disordered eating and eating disorders (EDs), is elevated among women athletes. The aim of this study was to explore body image facets and ED risk among female athletes in masculinised sports such as soccer. Forty-five federated amateur female soccer players from Spain participated in this study, voluntarily complying with an extensive evaluation protocol on attitudes towards body and appearance and eating practises. The participants overall reported self-representations of their bodies that corresponded to their reality as athletes, but their body ideals were also more demanding in terms of low fat and muscularity, in association with the functionality of their body and the physical demands of their athletic activity. Despite having a fairly high positive body image and body satisfaction, they also expressed negative attitudes towards their bodies. Around 2 out of 10 players were at risk of suffering from an ED. Players with negative attitudes towards their bodies had an odd 12 times likely to develop an ED compared to those with lower self-devaluation, after adjusting for BMI and body perceptions (OR = 12.3, p < 0.01). On the contrary, players who appreciate their bodies and hold a positive body image had an odd 83% lower to suffer from eating pathology, after adjusting for BMI and body satisfaction (OR = 0.17, p < 0.05). Our findings support the healthy and protective role of positive body image in sports contexts. Body attitudes should be addressed in preventive and therapeutic efforts for reducing the prevalence of EDs in women's sports, within both a “negative” and a “positive” paradigm of body image.

The Impairment of Body Image of the Students of Ağrı İbrahim Çeçen University Faculty of Sports Sciences and the Effect of the Anxiety of Caught Corona Disease on their Nutrition Habits

The aim of this study was to investigate the effect of body image and Corona disease anxiety on athlete’s eating disorders.The method of this research is descriptive and correlational. The statistical population Ağrı İbrahim Çeçen University Faculty of Sports Sciences, which is equal to 340 people. To determine the sample size, Cochran’s sample size estimation formula was used and the number of samples was equal to 181 people who were selected by simple random sampling method. Corona Disease Anxiety Scale (CDAS) by Alipour et al. (2019), Body Image Questionnaire by Cash et al. (1990) and Eating Disorders Questionnaire by Garner D, and Olmsted (1982) were used to collect data. SPSS software was used to analyze the data and regression coefficient was used to analyze the research hypotheses.The results show that body image has a significant negative effect on eating disorders (p &lt;0.05, Beta = -0.44). Corona anxiety also had a significant positive effect on eating disorders (p &lt;0.05, Beta = 0.56).Therefore, it can be concluded that with more attention to the body image,reflection on physical characteristics, satisfaction with different body parts and attitudes about weight, eating disorders decrease and with increasing Corona disease anxiety, eating disorders increase. Attitudes toward the body should be controlled and ways to get into Coronavirus anxiety should be limited.

Gender differences in symptom presentation and treatment outcome in children and youths with eating disorders

BackgroundTo address the gaps in the literature examining eating disorders among males and gender minority youths, a prospective study was designed to assess gender differences in eating disorder symptom presentation and outcomes. Muscularity concerns may be particularly relevant for male youths with eating disorders, and were included in assessment of eating disorder symptom presentation.MethodsAll cisgender male youths who presented for specialized eating disorder treatment at one of two sites were invited to participate, along with a group of matched cisgender females, and all youths who did not identify with the sex assigned to them at birth. Youths completed measures of eating disorder symptoms, including muscularity concerns, and other psychiatric symptoms at baseline and end of treatment.ResultsA total of 27 males, 28 females and 6 trans youths took part in the study. At baseline, Kruskal–Wallis tests demonstrated that trans youths reported higher scores than cisgender male and female youths on measures of eating pathology (Eating disorder examination-questionnaire (EDE-Q) and the body fat subscale of the male body attitudes scale (MBAS)). These analyses demonstrated that there were no differences between cisgender male and female youths on eating disorder symptoms at baseline. However, repeated measures ANOVA demonstrated that males had greater decreases in eating pathology at discharge than did females, based on self-reported scores on the EDE-Q, MBAS, and Body Change Inventory.ConclusionsGender differences in eating pathology appeared at baseline, with trans youths reporting higher levels of eating pathology than cisgender youths, though no differences between cisgender males and females emerged at baseline for eating disorder symptom presentation. Contrary to expectations, there were no gender differences in measures of muscularity concerns. Males demonstrated greater eating disorder symptom improvements than females, suggesting that male adolescents may have better treatment outcomes than females in some domains.

The Associations of Body Image Perception with Serum Resistin Levels in Highly Trained Adolescent Estonian Rhythmic Gymnasts.

Rhythmic gymnasts (RGs) are more likely to be dissatisfied with their body mass and shape compared to untrained controls (UCs). However, due to the lack of information, the aim of this study was to investigate the associations of body image perception (BIP) with body composition, daily energy consumption and different blood biochemical markers in adolescent RGs compared to UCs. Thirty-three highly trained RG girls and 20 UC girls aged 14–18 years participated in this cross-sectional study. Height, body mass, body composition, energy intake, resting energy expenditure, training volume and different blood biochemical markers were measured. The body attitude test (BAT) was used to evaluate the BIP of the participants. There were no differences in the total BAT scores between the groups. In RGs, the BAT score correlated positively with the serum resistin level (r = 0.35; p = 0.047). A stepwise multiple regression analysis showed that 40.8% of the variability in the BAT score was determined by resistin and BMI. The association of BIP with resistin values was observed only in RGs. In conclusion, our findings add to the increasing evidence that resistin may be a link between BIP and body composition, most likely through fat mass, in adolescent female RGs.

The Body Experience Questionnaire for adults with mild intellectual disability or borderline intellectual functioning (BEQ-mb): Development and initial evaluation

ABSTRACT Background Body experience is an important facet of psychosocial functioning and health. However, to date no test exists to measure body experience in adults with mild intellectual disability and borderline intellectual functioning (MID-BIF). We therefore adapted the Body Experience Questionnaire (BEQ) to this group, resulting in the BEQ-mb, and evaluated its usability, comprehensibility, and reliability. Method The BEQ-mb was developed in five stages: concept development, focus group, verbal reports, pilot testing, and evaluation. Results The BEQ-mb is applicable in, and comprehensible by, adults with MID-BIF. Internal consistency is good for the total scale and the body awareness and body satisfaction subscales, but low for the body attitude subscale. Test–retest reliability is excellent for the total scale and the subscales. Conclusion The BEQ-mb unlocks new opportunities for clinical examination and research on body experience. Future research is needed to investigate its structural validity.

Design, Development, and Testing of Package Delivery Quadrotor Biplane Tail-Sitter

This Paper explores the development of a novel hybrid air vehicle for package delivery called the quadrotor biplane tail-sitter. This vehicle uses differential thrust to effect body attitude changes like a traditional quadrotor, ensuring full transitional control between hover and forward flight modes. This method of control also allows the vehicle to remain mechanically simple. A vehicle was designed with a 1 lb (0.45 kg) payload, resulting in an 8 lb (3.63 kg) gross takeoff weight. The vehicle can hover using 15 in. (0.381 m) diameter proprotors and has two wings that span 3.35 ft (1.03 m), which provide lift in forward flight. Sensors were implemented onboard the vehicle to monitor individual dc brushless motor revolutions per minute, body attitude angles, electrical power consumption, and airspeed relative to wind. Stable hover was demonstrated with package delivery, and it was found that 18% less power was used when hovering with no payload compared to full payload. Package delivery was also successfully demonstrated after transitioning from hover to forward flight and back. In forward flight mode with no payload, the power consumption at a forward flight speed of () was seen to be 50% less than the power consumed in hover.

Unified Chassis Control of Electric Vehicles Considering Wheel Vertical Vibrations.

In the process of vehicle chassis electrification, different active actuators and systems have been developed and commercialized for improved vehicle dynamic performances. For a vehicle system with actuation redundancy, the integration of individual chassis control systems can provide additional benefits compared to a single ABS/ESC system. This paper describes a Unified Chassis Control (UCC) strategy for enhancing vehicle stability and ride comfort by the coordination of four In-Wheel Drive (IWD), 4-Wheel Independent Steering (4WIS), and Active Suspension Systems (ASS). Desired chassis motion is determined by generalized forces/moment calculated through a high-level sliding mode controller. Based on tire force constraints subject to allocated normal forces, the generalized forces/moment are distributed to the slip and slip angle of each tire by a fixed-point control allocation algorithm. Regarding the uneven road, H∞ robust controllers are proposed based on a modified quarter-car model. Evaluation of the overall system was accomplished by simulation testing with a full-vehicle CarSim model under different scenarios. The conclusion shows that the vertical vibration of the four wheels plays a detrimental role in vehicle stability, and the proposed method can effectively realize the tire force distribution to control the vehicle body attitude and driving stability even in high-demanding scenarios.

Vehicle attitude compensation control of magneto-rheological semi-active suspension based on state observer

This paper presents a vehicle attitude compensation algorithm based on state observer for vehicle semi-active suspension system equipped with four magneto-rheological dampers (MR dampers). The proposed algorithm including magneto-rheological damper control algorithm, attitude compensation control algorithm, and design method of state observer is to effectively improve ride comfort and control vehicle body attitude. First, the actual equivalent damping of magneto-rheological damper is introduced into state observer, and the parameter matrix of suspension system is updated in real time via precise discretization method to enhance the estimation accuracy of state observer. Then, the velocity signal estimated by state observer is employed as the evidence to realize attitude compensation control for vehicle body. Finally, relevant co-simulations and hardware-in-the-loop test are conducted to verify the validity of the proposed control algorithm. Results of simulations and tests demonstrate that the application of the control algorithm proposed in this paper can significantly improve ride comfort of magneto-rheological suspension and optimize vehicle body attitude.

Pressure to be Thin from a Religious Source Increases Perceived Pressure to be Thin in Women

Pressure to be thin through thin-idealization norms is something that women contend with daily in today’s world. Increased research has explored the effects this pressure can have on attitudes about the self. Religious beliefs and behaviors have been linked to decreased perceived pressure and positive body attitudes and behaviors. However, religious beliefs and behaviors have also been linked to negative outcomes in this area. This study explores the impact of pressure to be thin from a religious source. One hundred fifty-three women were either presented with pressure statements from a religious source, a family/friend source, or read no pressure statements. Women who read religious pressure statements reported more pressure to be thin than those in the control or family/friend pressure conditions.

INVESTIGATION OF THE RELATIONSHIP BETWEEN CLOSE PARTNER VIOLENCE, EMOTIONAL VIOLENCE AND DARK TRIAD PERSONALITY TRAITS

The aim of the study is to investigate the relationship between attitudes towards emotional violence and control behavior with dark triad personality traits together with physical and sexual violence against women. Another aim is to draw attention to psychological violence and control behaviors in the studies, to be carried out in the context of preventing intimate partner violence. The sample group consisted of 140 men aged 18 and over, who were reached through random sampling, reached through Google forms and face-to-face interviews. For the purposes of the research, the ISKEBE Violence against Women Scale (ISKEBE Attitude Scale) and Short Dark Triad Scale (SD3-T) were used, and personal information form was applied for demographic data. According to the statistics, men with a high dark triad total value have higher attitudes towards violence against women. There is a positive correlation between the high scores of psychopathy and body attitudes subscale scores. (B: 0.305, p &lt;0.001) A positive relationship was found between the high scores of narcissisms and the attitudes towards identity subscale. (B: 0.308, p &lt;0.001) There is a positive relationship between the high score of Machiavellianism and the attitudes towards identity subscale. (B: 0.470, p &lt;0.001)) There is a positive correlation between Machiavellian score and psychopathy score. (B: 0.515, p &lt;0.001). The results reveal that dark triad personality traits predict emotional and physical violence in close partner relationships.

Approbation of body investment scale on youth sample in Azerbaijan

IntroductionBody attitudes may serve as both vulnerability and protective factors for various forms of emotional and behavioral disorders, including suicidal and self-harm behaviors in adolescent and youth populations. Body Investment Scale (BIS, Orbach &amp; Mikulincer, 1998) is an instrument specially designed to account for body attitudes in suicide assessment.ObjectivesThe study was aimed to provide a preliminary evidence for using the BIS translation in the assessment of suicide risk factors in Russian-speaking student population in Azerbaijan.Methods The common recommendations for test translation were used. The factor structure, inter-item consistency of scales, and retest reliability were assessed. The participants were 100 students (18-23 years, 40 females, 60 males), 50 of them completed the retest.ResultsThe exploratory factor analysis with fixed number of factors reveals a homologous structure to the original BIS scales, explaining 48.2% of variance (in comparison to 55% of original measure). Inter-item reliability coefficients were lower: .989 for Body attitude, .696 for comfort with touch, .65 for Care and .61 for Protection scales. Pearson’s r for retest reliability (in a month) were above 0.9. Three items that could be excluded for enhancing the consistency of scales address physical contact and self-harm issues and might be culturally inappropriate.ConclusionsBIS is a promising instrument due to its grounded factor structure, but refinement of some items of the Russian translation is desired, as well as further study of applicability for adolescent population. BIS could fill the gap in scarcity of instruments for suicide assessment for Russian speaking population.DisclosureNo significant relationships.

Anti-swaying self-alignment method based on observation vector inertia for SINS under latitude uncertainty

The self-alignment of strapdown inertial navigation system that does not depend on any external aid still has huge application requirements. This study presents an anti-swaying self-alignment method based on the inertia tensor of gravity observation vectors and aims to improve the accuracy and efficiency of the latitude and attitude estimation by making full use of inertial measurements. The time-varying attitude matrix is decomposed first to isolate the swaying interference and gravity observation vectors are reconstructed to smooth the measurement noise. Then the body attitude estimation with unknown latitude is defined as an extended Wahba problem, which is solved by eigenvalue decomposition based on the inertia tensor of gravity observation vectors. Simulation and experiments verify the effectiveness of the proposed method and two common methods are used for comparison, which show that the proposed method has faster convergence speed, stronger anti-interference ability, and higher accuracy of the latitude and attitude estimation.

An attitude updating algorithm using Picard iteration and higher degree polynomial

To accurately track body attitude under high dynamic environments, a new attitude updating algorithm for the strapdown inertial navigation system is proposed after further applying higher degree polynomial to the quaternion Picard iteration (QPI) algorithm. With QPI, calculation error introduced by Picard approximation can be eliminated, but the angular rate fitting error introduced by substituting polynomial for angular rate of body will still affect the accuracy of the attitude updating algorithms which are designed based on polynomial model. Hence, a five- rather three-degree polynomial constructing method using four samples of gyro outputs with coning motion constrain is designed and tested. Simulation results indicate the proposed method owns more accuracy than QPI, optimal coning algorithm, and Fourth4Rot under both low and high dynamic environments.

Total Least-Squares Determination of Body Segment Attitude.

To examine segment and joint attitudes when using image-based motion capture, it is necessary to determine the rigid body transformation parameters from an inertial reference frame to a reference frame fixed in a body segment. Determine the rigid body transformation parameters must account for errors in the coordinates measured in both reference frames, a total least-squares problem. This study presents a new derivation that shows that a singular value decomposition-based method provides a total least-squares estimate of rigid body transformation parameters. The total least-squares method was compared with an algebraic method for determining rigid body attitude (TRIAD method). Two cases were examined: case 1 where the positions of a marker cluster contained noise after the transformation, and case 2 where the positions of a marker cluster contained noise both before and after the transformation. The white noise added to position data had a standard deviation from zero to 0.002 m, with 101 noise levels examined. For each noise level, 10 000 criterion attitude matrices were generated. Errors in estimating rigid body attitude were quantified by computing the angle, error angle, required to align the estimated rigid body attitude with the actual rigid body attitude. For both methods and cases, as the noise level increased the error angle increased, with errors larger for case 2 compared with case 1. The singular value decomposition (SVD)-based method was superior to the TRIAD algorithm for all noise levels and both cases, and provided a total least-squares estimate of body attitude.

Young Women’s Body Attitudes and Sexual Satisfaction: Examining Dehumanization and Communication as Serial Multiple Mediators

Women’s bodies are frequent sites of stigmatization. The internalization of negative attitudes toward the body can have negative implications for women’s sexual wellbeing. In the current study, we examined the relationships between young women’s internalization of body stigma—including body shape, genitals, and menstrual periods—and sexual satisfaction. Additionally, we tested two mechanisms that may mediate the relationship between body attitudes and sexual satisfaction: dehumanization (i.e., feelings of a loss of autonomy and subjectivity) and communication with a sexual partner (e.g., expressing needs and desires). We collected and analyzed survey data from 569 undergraduate women. We tested serial mediation models, such that more negative body attitudes would predict greater feelings of dehumanization, and more dehumanization would predict less comfort communicating with a sexual partner, and less comfort communicating would then predict decreased sexual satisfaction. We found support for serial mediation, which suggests that the links between body attitudes and sexual satisfaction may be partially explained by feelings of dehumanization and communication with a sexual partner. Our findings identify opportunities for intervention in practice and policy, and further clarify the ways that sociocultural stigma surrounding women’s bodies extends beyond the body—affecting women’s feelings of power, relationships, and sexual lives.

Non-suicidal self-injury in patients with eating disorders: nuclear aspects.

Background: Through the culture of thinness, increasingly promoted in our society as a beauty canon, it is not surprising that the number of people affected by eating disorders is increasing.Objective: This research aims to study the relationship between non-suicidal self-injuries and nuclear aspects of eating disorders specified along with this article.Methods: The sample consisted of 60 women diagnosed with anorexia and bulimia. Questionnaires assessing impulsivity, body satisfaction, alexithymia, body attitude and self-esteem were administered. Participants with non-suicidal self-harm were compared with those without it, and participants with anorexia with and without self-harm and participants with bulimia with and without self-harm were compared.Results: Differences were found in body dissatisfaction= 5.71; p ≤0.01), body attitudes= 4.80; p ≤0.02), self-esteem= 14.09; p ≤0.00) and impulsivity (t= 3.39; p ≤0.01) between participants with and without non-suicidal self-harm.Conclusions: These are key factors for the clinical area in the treatment of eating disorders to prevent the presence of self-harm, as it allows focusing the treatment target on those aspects such as dissatisfaction and impulsivity, which are key in the development of self-harm.

Neuropeptide Y and Peptide YY in Association with Depressive Symptoms and Eating Behaviours in Adolescents across the Weight Spectrum: From Anorexia Nervosa to Obesity.

Neuropeptide Y (NPY) and peptide YY (PYY) are involved in metabolic regulation. The purpose of the study was to assess the serum levels of NPY and PYY in adolescents with anorexia nervosa (AN) or obesity (OB), as well as in a healthy control group (CG). The effects of potential confounders on their concentrations were also analysed. Eighty-nine adolescents were included in this study (AN = 30, OB = 30, and CG = 29). Anthropometric measurements and psychometric assessment of depressive symptoms, eating behaviours, body attitudes, and fasting serum levels of NPY and PYY were analysed. The AN group presented severe depressive symptoms, while the OB group held different attitudes towards the body. The levels of NPY were lower in the AN and OB groups as compared with the CG. The PYY levels were higher in the OB group than in the AN group and the CG. The severity of eating disorder symptoms predicted fasting serum concentrations of NPY. Lower levels of NPY in AN, as well as in OB suggests the need to look for a common link in the mechanism of this effect. Higher level of PYY in OB may be important in explaining complex etiopathogenesis of the disease. The psychopathological symptoms may have an influence on the neurohormones regulating metabolism.

Study of Body Attitude Criteria of Indoor Hockey Players Based on Body Height to Obtain Accurate Shooting Techniques

The purpose of this study was to make a preliminary study of the criteria for accurate shooting techniques based on height. Researchers in this study analyzed an accurate ball shooting technique based on body posture consisting of the initial attitude, the execution attitude, and the final attitude. The posture of the ball shooting technique has been demonstrated by indoor hockey players at the Sports Science Faculty, Jakarta State University. The data obtained in this study were taken through observation, interviews, and filling out questionnaires. This study uses a qualitative method by distributing questionnaires to each player. The population used was the hockey athlete at the State University of Jakarta. The sample was taken in this study using a total sampling technique. The results of this study the respondents stated that playing experience, comfort, The body postures of the respondents support the ability to shoot the ball accurately, respectively, shown by the percentage strongly agree and agree are 45% and 44%, 52% and 44%, 70% and 30%. Furthermore, for height, the largest percentage was 44% disagreed and 26% doubtful, for arm length the largest percentage was 45% doubtful and 41% disagreed. This means that height and arm length do not affect the respondent's accuracy in shooting the ball accurately. However, the distance between the hand grips affects the accuracy and comfort, this is reinforced by the percentage strongly agree and agree that the hand grip distance affects the accuracy is 19% and 59% and the distance between the handles based on comfort is 33% and 56%. The results of this study will be given to athletes and coaches as evaluation material.

Study of Body Attitude Criteria of Indoor Hockey Players Based on Body Height to Obtain Accurate Passing Techniques

In this study, the authors analyzed the posture of indoor hockey players for ball passing techniques based on posture which consists of initial attitude, implementation attitude, and final attitude. These three gestures have been demonstrated by a male indoor hockey player from the Sports Science Faculty, Jakarta State University. Data was collected in September at Hall B, Room Hockey Field, Faculty of Sports Science, Jakarta State University. The data obtained in this study were obtained through filling out questionnaires, observations, and interviews. The aim of this research is to determine the ideal height of a indoor hockey player who has accurate passing techniques. The samples in this study were all male indoor hockey athletes at the State University of Jakarta who followed a quasi-experimental research method with a time series design on indoor hockey passing techniques. As a result, we will get data on height and body position when doing the passing technique and the accuracy of the technique. Then from this study the respondents stated that the experience of playing, comfort, and body posture of the respondents supported the ability of the passing technique, which respectively indicated by the percentages of strongly agreeing and agreeing that were 63% and 30%, 52% and 48%, 56% and 37%. Furthermore, in terms of height, the largest percentage was 45% disagreed, 11% strongly disagreed and 33% doubted. Whereas in the case of 52% disagree, 4% strongly disagree and 33% are doubtful and in terms of the distance between hand grips it affects the accuracy of the passing technique with a percentage of 59% agree and 4% strongly agree. We're going to give some recommendations for coaches and hockey players to have multiple height classifications with postures that give better accuracy for passing the ball.
