Background: The Knee Injury Osteoarthritis Outcome Score (KOOS) is a widely used patient-reported questionnaire to evaluate individuals with knee osteoarthritis or a history of knee injuries. Objectives: The aim of this study was to evaluate the responsiveness and establish the minimal important change (MIC) for the Arabic version of KOOS in Iraqi individuals with knee osteoarthritis following physiotherapy intervention. Methods: Fifty volunteers (13 male and 37 female, mean age: 59.3±9.6 years old) with an orthopedic diagnosis of knee osteoarthritis participated in this study. The Arabic KOOS was completed by the participants once before the intervention and once after completing a 4-week physiotherapy treatment program. A seven-item global rating of change scale was used as an external anchor to assess the participants' opinion about the treatment and its possible changes. Responsiveness was evaluated by calculating the receiver operating characteristic (ROC) curve, and the MIC was established by identifying an optimal cut-off on the ROC curve. Results: All subscales of the Arabic KOOS showed an area under the curve > 0.70. The MICs reflecting the values required by the participants to feel the improvement were 15.5, 14.5, 11, 11.5, and 12.5 for the pain, symptoms, activities of daily living, sports and recreation, and quality of life subscales, respectively. Conclusions: All subscales of the Arabic KOOS are responsive to physiotherapy treatment. Therapists and researchers can use the MIC values to evaluate whether their prescribed treatment was satisfactory and effective from their patients' point of view.

Background: In recent years, coaches and athletes have increasingly used observation as a tool for teaching and learning sports skills. Objectives: The aim of this study was to investigate the impact of modeling, using internal and external attentional focus strategies, on the acquisition and retention of free throw shooting in basketball. Methods: Forty-five female beginner basketball players (aged 21.62 ± 3.08 years, with a BMI of 23.48 ± 0.99 kg/m2) voluntarily participated in this study. Based on their pre-test scores using the ABBA method, they were divided into three groups: one group received modeling with an internal attention focus strategy, another group received modeling with an external attention focus strategy, and a control group. A video demonstrating the correct throwing technique was used to teach the attention-focusing strategies, and the groups did not receive any physical training. After watching the video, participants performed their own throwing attempts. Following group allocation, the participants entered the acquisition phase, which consisted of six sessions, with each session including two sets of ten attempts and a 2-minute rest period between sets. One-way analysis of variance was used for both immediate and delayed recall tests, and data analysis was conducted using SPSS 20 software.” Results: The study found a significant difference in free throw performance between the three modeling groups (internal attention focus, external attention focus, and control) during both the acquisition and delayed retention stages (P ≤ 0.05). Additionally, there was a significant difference in basketball free throw performance between the three modeling groups during the recall test (P ≤ 0.05). Conclusions: Overall, the results suggest that observational learning, combined with attentional focus strategies, is an effective method for improving skill acquisition and retention in basketball.

Background: Undiagnosed eating disorders may lead to a life-threatening condition, then a validated and reliable tool that lets health providers use it for effective screening is a mandatory need. Objectives: This study aimed to assess the validity and reliability of the Persian version of the Eating Disorder Inventory-3 Referral Form (EDI-3 RF). Methods: In this cross-sectional study, 452 university students and employees were recruited by convenience sampling from the Iran University of Medical Sciences, Tehran, Iran. The content validity was assessed using the five specialists, and then the content validity index (CVI) and content validity ratio (CVR) was calculated separately. The reliability was measured with Cronbach’s alpha and test-retest. Results: Overall, 260 participants filled out the questionnaire completely. The mean age of participants was 22.34 ± 4.18 years. The mean weight was 64 kg (range: 40 - 115). This version of EDI-3 RF yields acceptable content validity and item correlation. According to the expert’s opinion, CVR was more than 0.99 for all inquiries. Also, the CVI for each item was greater than 0.79, which indicates the acceptable value of this index for different items in terms of relevance, clarity, and simplicity. Also, the face validity was approved according to participants’ and experts’ opinions. Cronbach’s alpha for measuring the three subscales of an eating disorder were acceptable (drive for thinness (DT) = 0.76 and 0.77, bulimia (B) = 0.71 and 0.72, and body dissatisfaction (BD) = 0.77 and 0.71, respectively). The correlation coefficient between two questionnaires was 0.48 (P < 0.01). The coefficient between the subscales and whole parts of this questionnaire was 0.58, 0.53, 0.66, 0.48, 0.34, and 0.43, respectively (P < 0.01). Conclusions: This questionnaire would be a beneficial self-response questionnaire, and because of its abbreviated format, it can be used as a screening and referral tool in the Persian population.

Context: Mental health problems are extremely common all over the world and contribute significantly to illness and impairments. There is an acknowledged need for interventions that focus on prevention to foster mental health, and to fulfill this need, sports offer a promising way to promote mental health and avoid the beginning of a mental illness. In this study, a literature review is presented about the association between sports participation and mental health across the lifespan. Objectives: To determine the association between sports participation and mental health and get information about the mental health benefits that can be achieved by increased participation in sports, both by the general public and professional athletes at any age. Methods: To conduct the literature review, a search on different databases was carried out for research articles with the key terms "sports participation” and “mental health" to find their association. Results: Participation in sports was found to be positively associated with psychological well-being and connected with fewer mental health problems. Sports participation was associated with higher self-esteem and a lower risk of anxiety, depression, and social-behavioral inhibition in adolescents. Sports participation led to reduced smoking and a type of personality that was resistant to alcohol and drug addiction. Sports club membership, high or moderately frequent sports participation, participation in outdoor sports, team sports, contact sports, and competition were all linked to fewer internalizing problems. Conclusions: Participation in sports is beneficial to the mental health of children, adolescents, and adults. Team sports and sports clubs are especially advantageous for mental health due to social and psychological support. Creating opportunities for sports participation can lead to the promotion of mental health.

Background: Stress and anxiety related to post-injury trauma in athletes is a latent problem in sport. The use of eye movement desensitization and reprocessing (EMDR) allows sports psychologists to intervene with their athletes more effectively to help them into their recovery and achieve peak sport performance. Objectives: Analyze the EMDR therapy effect in the psychophysiological responses of four athletes with stress related to a traumatic event during sports practice. Methods: Four athletes (22.25 ± 1.71 years; 11.5 ± 2.65 years of experience) participated in a single-group pre-experimental study. The Sport Psychology Department of the institution approved the study for its application, which also followed the statement of the declaration of Helsinki. The participants had been medically cleared to practice their sport after sustaining a severe injury, but they expressed significant difficulty in performing optimally yet. The Competitive State Anxiety Inventory-2RD was applied to measure the anxiety and self-confidence levels before, after and two weeks later EMDR therapy intervention. Eye movement desensitization and reprocessing standard protocol therapy was carried out to identify the dysfunctional memories to be reprocessed, address the abnormal behaviors as trauma consequences, and develop the behavioral changes to manage the trauma. Heart rate variability parameters used as biofeedback were monitored during the EMDR protocol to associate with moments of stress and relief. Data analysis was performed using the smallest worthwhile change (SWC) of Hopkins to compare the results in the different moments of the protocol and study. Results: All four athletes reported likely and most likely beneficial changes (according to the SWC) in their levels of anxiety and self-confidence after the intervention with the EMRD therapy as well as at two weeks afterward. Heart rate variability (HRV) parameters linked with parasympathetic activity were reduced and the sympathetic parameters increase their levels when the intervention protocol induced stressor memories, observing an opposite behavior when EMDR phases let the athlete be relaxed or getting relief. Conclusions: Eye movement desensitization and reprocessing is a therapy is effective to manage a sport injury related psychologic trauma. Furthermore both, LnRMSSD and LnSS parameters of the HRV can be used as a biofeedback strategy for a better efficacy of EMDR-based treatment.
背景:与运动员损伤后创伤相关的应激和焦虑是运动中的潜在问题。眼动脱敏和再处理(EMDR)的使用使运动心理学家能够更有效地干预他们的运动员，帮助他们恢复并达到最佳运动表现。目的:分析EMDR疗法对4名运动员运动训练中创伤性事件应激心理生理反应的影响。方法:4例运动员(22.25±1.71岁;(11.5±2.65岁)参加单组预实验研究。该机构的运动心理学系批准了这项研究的应用，这也是遵循赫尔辛基宣言的声明。在经历了一次严重的受伤后，这些参与者已经在医学上被允许练习他们的运动，但他们表示要达到最佳状态仍然有很大的困难。采用竞争状态焦虑量表(Competitive State Anxiety Inventory-2RD)测量EMDR治疗干预前、干预后和干预后两周的焦虑和自信水平。采用眼动脱敏和再加工标准方案治疗，识别需要再加工的功能障碍记忆，将异常行为视为创伤后果，并发展行为改变来管理创伤。在EMDR方案期间，监测心率变异性参数作为生物反馈，以与压力和缓解时刻相关联。数据分析采用霍普金斯最小价值变化(SWC)来比较方案和研究不同时刻的结果。结果:所有四名运动员在EMRD治疗干预后以及两周后的焦虑和自信水平上都报告了可能和最有可能的有益变化(根据SWC)。当干预方案诱导应激源记忆时，与副交感神经活动相关的心率变异性(HRV)参数降低，交感神经参数水平增加，而当EMDR阶段让运动员放松或得到缓解时，观察到相反的行为。结论:眼动脱敏再加工是一种治疗运动损伤相关心理创伤的有效方法。此外，HRV的LnRMSSD和LnSS参数都可以作为生物反馈策略，以获得更好的基于emdr的治疗效果。

Background: Some chemokines like C C motif chemokine ligand (CCL) 2 and 5 and their receptors (CCR) 2 and 5 are mediators of chronic inflammation and cancer development. Moreover, physical exercise can increase the activity of antioxidant enzymes. However, its effect on cancer cells has not been reported at present. Objectives: Therefore, the present study aimed to ascertain the effect of 12-week aerobic exercise training (AET) on CCL2, CCR2, CCL5, and CCR5 in mice with breast cancer. Methods: Sixteen Balb/c mice aged 4 - 5 weeks (n = 16; approximate weight: 18 ± 2 g) were divided into two groups: AET group (AETG) and control group (CG) (n = 8 per group). The AETG performed 12-week treadmill running at 18 m/min for 40 min and five times a week. Plasma levels of CCL2 and CCL5 were measured by ELISA, and the CCR2 and CCR5 were evaluated by Western blotting. Two independent sample t-test was applied to compare the differences between AETG and CG. Results: The analysis displayed after 12 weeks showed a significant reduction in AETG compared to CG in CCL2 (3.94 ± 1.12 vs. 15.40 ± 3.29 pg/ml; P = 0.001), CCR2 (0.56 ± 0.19 vs. 1.00 ± 0.001; P = 0.002), CCL5 (138.59 ± 15.72 vs. 267.57 ± 49.06 ng/ml; P = 0.001) and CCR5 (0.36 ± 0.12 vs. 1.00 ± 0.001; P = 0.001), respectively. Conclusions: We concluded that one of the main mechanisms of a positive effect of exercise on breast cancer is reducing the inflammation via CCL2 and CCL5 and their related receptors CCR2 and CCR5, respectively. Since these molecules can be triggered off oxidative stress and tumorigenesis, these results can pave the way for further studies in this field.

Background: Variations in plasma volume and hematological parameters occur before and after training in soccer players. However, there are no reports on changes in hematological parameters resulting from a half-season of training in professional soccer players. Objectives: To investigate the effects of training load on plasma volume variations in elite soccer players. Methods: Twenty soccer players from the 1st French division soccer league (Ligue 1) were included in the study. The training load was evaluated using the rating of perceived exertion (RPE, 10- Borg scale) after each training session and each match. Anthropometrics characteristics, hematocrit (Ht), hemoglobin (Hb) and plasma volume variations (PVV) were assessed at 3 different times: T1: Baseline (before the first week of pre-season), T2: At the end of pre-season (after 8 weeks of training) and T3: At the end of the first competitive period (after 26 weeks of training and at halfway of the competitive season). Results: Values of Ht and lean body mass (LBM) increased during the first competitive period from T1 to T3 (Ht: ∆↑8%, P = 0.037, effect sizes (ES) = 1.0; LBM: ∆↑4%, P = 0.041, ES = 0.83) and from T2 to T3 (LBM: (∆↑2%; P = 0.05; ES = 0.77). Moreover, PVV decreased from T2 to T3 (P = 0.002, ES = 0.5) and from T1 to T3 (P < 0.05; ES = 1.26). There were no differences in Hb at T1, T2 or T3. Conclusions: Changes in body weights, PVV and Ht during preparatory and competitive phases were affected by the training load and competitive play.

Methods: Twenty soccer players from the 1st French division soccer league (Ligue 1) were included in the study. The training load was evaluated using the rating of perceived exertion (RPE, 10- Borg scale) after each training session and each match. Anthropometrics characteristics, hematocrit (Ht), hemoglobin (Hb) and plasma volume variations (PVV) were assessed at 3 different times: T1: Baseline (before the first week of pre-season), T2: At the end of pre-season (after 8 weeks of training) and T3: At the end of the first competitive period (after 26 weeks of training and at halfway of the competitive season). Results: Values of Ht and lean body mass (LBM) increased during the first competitive period from T1 to T3 (Ht: ∆↑8%, P = 0.037, effect sizes (ES) = 1.0; LBM: ∆↑4%, P = 0.041, ES = 0.83) and from T2 to T3 (LBM: (∆↑2%; P = 0.05; ES = 0.77). Moreover, PVV decreased from T2 to T3 (P = 0.002, ES = 0.5) and from T1 to T3 (P < 0.05; ES = 1.26). There were no differences in Hb at T1, T2 or T3. Conclusions: Changes in body weights, PVV and Ht during preparatory and competitive phases were affected by the training load and competitive play.","PeriodicalId":118920,"journal":{"name":"International Journal of Sport Studies for Health","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127561452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: In sport context learning a skill, and performing it flawlessly is of great importance. There is a unanimous consensus among sport scientists, coaches, and athletes, that along with physical, technical and tactical skills, psychological skills are also necessary for an optimal sport performance. Objectives: The aim of the present study was to investigate the role of mental toughness in motor learning and sport performance in wrestling. Methods: This study was semi-experimental and its population were physical education students of the University of Tehran in 2018. Using intensive sampling method, 28 student-athletes, who never had any past wrestling skill practices, were selected. Subsequently, using Mental Toughness-48 questionnaires, they were divided into two equal groups of high and low in mental toughness. After that, all participants were randomly assigned into two groups of equal size and 30 wrestling skills were taught to them twice a week for 3 months by two professional wrestling coaches. Their motor learning was assessed by three other professional coaches in the last week of training and one week after the last session. Motor learning score was obtained by calculating the mean scores of acquisition and retention stages. Then, two groups with high and low levels of mental toughness were compared regarding their motor learning scores. Tools used in this study included demographic consent form, wrestling skills test and The Mental Toughness Questionnaire-48 (MTQ 48). Results: The results suggested that mentally tough student-athletes demonstrated significantly higher motor learning scores compared with their counterparts who had lower levels of mental toughness (P ≤ 0/05). This advantage was persistent both in the acquisition and retention stages (P ≤ 0/05). Conclusions: It was concluded that mental toughness could be considered as a key factor in motor learning. Therefore, it is recommended to coaches and athletes to develop mental toughness in order to enhance motor learning and achieve successful performance.

Background: Pubertal development and sexuality in prime adolescence can individually or both affect academic performance during the secondary cycle. Objectives: The present study aims to examine the relationship between pubertal maturation, sexuality and academic Performance of secondary school students. Methods: Data were collected via a cross-sectional survey after the release of the first quarter results. The sample was composed of 418 students (195 boys and 223 girls aged 13.96 ± 0.97 and 14.26 ± 0.85 years old respectively). The pubertal development scale and sexuality at prime adolescence scales were used to collect data. Academic performance was assessed based on quarterly cumulative GPA. Chi-square and Pearson's correlation tests were used and responses were structured into subcategories regarding factors of pubertal development, sexuality and academic performance. Results: The pubertal development of girls was more advanced than that of boys; the boys scores on the "going out with someone" scale (P ≤ 0.05) and on the “flirting with the aim of having sexual relations” scale (P ≤ 0.01) whereas girls scores on the "giving priority to love" scale (P ≤ 0.05). In general academic performance was above mean and below mean respectively for boys and girls. Pubertal development and sexuality were negatively correlated with academic performance mostly in girls. Conclusions: The developmental stage was more pronounced in girls. Boys were ahead in sexuality and the mean of their academic performance was higher. The interactions of development and sexuality and their combined effect negatively influenced the academic performance of girls and boys with gender-specific degrees.

Background: Recent research has focused on the effects of different types of strength training on the performance and body profile of adolescent athletes. However, the effects of short-term plyometric and jump rope training on body profile and athletic performance in adolescent basketball players are a matter of curiosity. Objectives: The aim of this study was to examine the effects of short-term plyometric and jump rope training on body profile and athletic performance in adolescent basketball players. Methods: Twenty-two basketball players aged 13 - 15 were randomly divided into two groups as plyometric (n = 11) and jump rope training group (n = 11). All participants regularly completed to plyometric or jump rope training as 10 units for 4-weeks in addition to basketball training. Somatotype, body composition, push-up & sit-up test, sprint, agility (Illinois & hexagon), jump (vertical, squat, horizontal, plyometric) tests were measured before and end of the study. Results: The push-up (P = 0.049 vs < 0.001), sit-up (P = 0.20 vs < 0.001), squat jump (P = 0.010 vs 0.003) and horizontal jump (P = 0.028 vs 0.014) of the players were significantly increased after 4-weeks plyometric and jump rope training. In addition, plyometric jump (P = 0.007) and hexagon performance (P = 0.001) were significantly increased in jump rope training group. At the end of 4-weeks, body mass, endomorphy and ectomorphy scores of the lower limb plyometric training group, and body mass index, endomorphy & mesomorphy scores and quadriceps circumference of the jump rope training group were significantly increased. Conclusions: Short-term plyometric and jump rope training affect the body profile and athletic performance of the adolescent basketball players, but jump rope training has a more significant effect on athletic performance than plyometric training. Therefore, jump rope training is recommended for coaches who want to gain more athletic performance in a short-term.
背景:最近的研究集中在不同类型的力量训练对青少年运动员的表现和身体特征的影响。然而，短期增强训练和跳绳训练对青少年篮球运动员身体轮廓和运动表现的影响是一个令人好奇的问题。摘要目的:探讨短期增强式训练和跳绳训练对青少年篮球运动员身体形态和运动表现的影响。方法:将22名13 ~ 15岁的篮球运动员随机分为增强训练组(n = 11)和跳绳训练组(n = 11)。所有参与者在进行篮球训练的同时，定期完成10个单元的增强式或跳绳训练，为期4周。在研究开始前和结束时测量体格、身体组成、俯卧撑和仰卧起坐测试、短跑、敏捷性(伊利诺伊和六边形)、跳跃(垂直、深蹲、水平、增强式)测试。结果:运动员的俯卧撑(P = 0.049 vs < 0.001)、仰卧起坐(P = 0.20 vs < 0.001)、深蹲跳(P = 0.010 vs 0.003)、水平跳(P = 0.028 vs 0.014)在4周增强式训练和跳绳训练后均有显著提高。此外，跳绳训练组增强式跳跃(P = 0.007)和六边形表现(P = 0.001)显著提高。4周结束时，下肢增强训练组的体质量、内形态和外形态评分以及跳绳训练组的体质量指数、内形态和中形态评分和股四头肌围围均显著升高。结论:短期增强式训练和跳绳训练对青少年篮球运动员的身体形态和运动成绩有影响，但跳绳训练对运动成绩的影响比增强式训练更显著。因此，对于想要在短期内获得更多运动成绩的教练来说，跳绳训练是推荐的。
