The purpose of this study was to evaluate the phases of change of exercise among male workers and to analyze the factors affecting their EB using Information-Motivation-Behavioral skill-Revealed Related Variables (IMBR) model. The study included 163 male workers from a major Hyundai Transys company, Seosan city. Data were analyzed using Pearson’s correlation coefficients, and hierarchical regression etc. Regarding the phases of change in exercise, 135 individuals (82.8%) were classified into phase 3 (preparation phase), phase 4 (action phase), and phase 5 (maintenance phase). In the first step, factors such as health status (β = 0.26 , p < 0.001), smoking (β = 0.16, p= 0.005), number of exercises per week (β = 0.35, p < 0.001), times of each exercise (β = 0.17, p = 0.005), and phases of change in exercise (β = 0.17, p = 0.014) were identified as significant factors affecting EB. In the second step, health status (β = 0.19, p = 0.001), smoking (β = −0.13, p = 0.019), number of exercises per week (β = 0.31, p < 0.001), phases of change in exercise (β = 0.13, p = 0.034), and sport commitment (β = 0.16, p = 0.019) were identified as significant factors. In the third step, health status (β = 0.27, p < 0.001), number of exercises per week (β = 0.14, p = 0.005), and exercise self-efficacy (β = 0.39, p < 0.001) were identified as significant factors, explaining 68.3% of the variance in EB. To promote EB, it’s important to assess the phases of change in exercise and consider factors such as health status, smoking, the number of exercises per week and the duration of each exercise. Interventions that enhance sport commitment and exercise self-efficacy should be considered. It’s recommended to apply IMBR model in exercise studies for workers.
本研究采用信息-动机-行为-技能显示相关变量(IMBR)模型，探讨男性工人运动习惯的变化阶段，并分析影响其运动习惯变化的因素。这项研究的对象是瑞山市现代transsys公司的163名男性员工。采用Pearson相关系数、层次回归等方法对数据进行分析。关于运动变化的阶段，135人(82.8%)被分为阶段3(准备阶段)、阶段4(行动阶段)和阶段5(维持阶段)。在第一步中，健康状况(β = 0.26, p <0.001)、吸烟(β = 0.16, p= 0.005)、每周锻炼次数(β = 0.35, p <0.001)、每次运动次数(β = 0.17, p = 0.005)和运动变化阶段(β = 0.17, p = 0.014)是影响EB的显著因素。在第二步中，健康状况(β = 0.19, p = 0.001)，吸烟(β = - 0.13, p = 0.019)，每周锻炼次数(β = 0.31, p <0.001)、运动变化阶段(β = 0.13, p = 0.034)和运动承诺(β = 0.16, p = 0.019)被认为是显著因素。第三步，健康状态(β = 0.27, p <0.001)、每周运动次数(β = 0.14, p = 0.005)和运动自我效能感(β = 0.39, p <0.001)被认为是显著因素，解释了68.3%的EB方差。为了促进EB，重要的是评估运动变化的阶段，并考虑健康状况、吸烟、每周运动的次数和每次运动的持续时间等因素。应考虑提高运动承诺和运动自我效能的干预措施。建议将IMBR模型应用于工人运动研究。

Arthroscopic partial meniscectomy (APM) strives to preserve knee biomechanics and function after the meniscal rupture. However, patients undergoing APM experience long-term impacts like proprioceptive deficit and functional decline. This study aimed to examine and compare the effects of aquatic and leg cycling trainings on young athletes undergone APM. Ninety-seven male athletes with APM were assigned to aquatic training group (ATG, n = 49) and cycling training group (CTG, n = 48). Both intervention trainings were conducted three times a week for 6 weeks after 2 weeks of APM. The rehabilitation training was the same in each session. The International Knee Documentation Committee (IKDC) questionnaire scores, knee joint position sense, Y-balance test, and isokinetic knee strength were measured before and after the interventions. Significant improvements were observed after the trainings regarding measured variables for both ATG and CTG groups. Comparison of the two groups found that ATG group had higher scores in IKDC and Y-balance test, greater muscle power, and lower absolute error in the joint position sense test compared to the CTG group. ATG and CTG are thus considered effective training interventions in early rehabilitation phase following the APM. Moreover, ATG may be more conducive than CTG in improving subjective knee symptoms, proprioception, and muscle power.
关节镜半月板部分切除术(APM)旨在保护半月板破裂后膝关节的生物力学和功能。然而，接受APM的患者会经历本体感觉缺陷和功能下降等长期影响。本研究旨在探讨和比较水上和腿部自行车训练对年轻APM运动员的影响。将97名男性APM运动员分为水上训练组(ATG, n = 49)和自行车训练组(CTG, n = 48)。两种干预训练均在APM治疗2周后进行，每周3次，持续6周。每次的康复训练都是一样的。在干预前后测量国际膝关节文献委员会(IKDC)问卷得分、膝关节位置感、y -平衡测试和膝关节等速力量。ATG组和CTG组在训练后观察到关于测量变量的显著改善。两组比较发现，与CTG组相比，ATG组在IKDC和Y-balance测试中得分更高，肌肉力量更大，关节位置感测试的绝对误差更小。因此，ATG和CTG被认为是APM后早期康复阶段有效的训练干预措施。此外，ATG可能比CTG更有利于改善主观膝关节症状、本体感觉和肌肉力量。

Explosive strength has a decisive role in the rapid execution of movements and in achieving sports performance. The purpose of the study is to identify the differences in the level of explosive force for the upper and lower body, depending on the involvement in curricular physical activities, leisure physical activities or physical efforts in various sports disciplines. The participants are students of the Faculty of Physical Education and Sport/bachelor’s degree: 147 men (age = 20.82 years old). The study was based on a transversal research, with the division of students into 3 distinct investigation groups (as an independent variable), according to sports majors: IS (individual sports), TSG (team sports games) and NA (non-athletes). 7 lower body explosive force evaluation tests and 6 upper body explosive force evaluation tests were applied. The use of ANOVA/Analysis of variance and the comparison on pairs of sports specializations indicate statistically significant differences for most of the tests, between the TSG and NA, respectively IS and NA groups, with the superiority of the athletes. No significant differences are reported between the TSG and IS groups, with 2 exceptions: in the 30s-Plyometric Push-Ups the IS group has significantly better values, respectively in the 30s-lateral hop for the TSG group (p ≤ 0.05). The results of our study are in line with the average performance values provided by other research in the field (although they are weaker than those of elite athletes). The superiority of the individual values of volleyball players and sprinters/Track and field for the power of the lower body, respectively of combat sports practitioners and practitioners of sports games—which use the muscle groups of the trunk and arms in training—for the power of the upper body is confirmed, so the specificity of the effort also influences the explosive force values.

Family planning falls within the spectrum of care within our medical society. We sought to illustrate changes in contraceptive methods over time and evaluate tubal ligation and vasectomy reversal practices in Australia. Yearly data from 2000 to 2021 was extracted from 3 databases: Pharmaceutical Benefits Schedule, Medicare Benefit schedule and Australian Institute of Health and Welfare databases. Population adjusted rates of procedures and medical therapies were calculated using data from Australian Bureau of statistics. Use of Long acting reversible contraception (LARC) has increased by 34.1% from 2001 to 2021, with Mirena being the preferred contraception. The peak age group for tubal ligation during caesarean section was those >35-year-old (64.7%) whereas vasectomy more commonly performed in men aged 35–44. There was a 21.6% decrease in the number of vasectomies over time from 2000–2020. Female surgical sterilisation:vasectomy ratio shows tubal ligation was twice more common than vasectomy. Both macro/microsurgical anastomosis of the vas deferences were conducted: vasovasostomy (VV) and vasoepididymostomy (VE). There was a preponderance in the use of microsurgical approach for VV. Reversal mostly common occurred in those aged 40–44 at 29%. Overall, the rate of vasectomy is continuously falling over time whilst there is a steady incline in the use of LARC from 2020–2021. Both vasovasostomy and vasoepididymostomy reconstruction are practised. Although definitive conclusion from the literature lags, “real-world” trend indicate that micro-surgically conducted vasovasostomy might be the better surgical technique for desired patient outcomes.

The purpose of this study was to check the moderating role of individualism/collectivism in predicting male Chinese university students’ exercise behavior using the theory of planned behavior (TPB) model. The TPB model was validated through SEM (structure equation model), and the moderating effect of individualism and collectivism was validated through a hierarchical regression and simple slopes analysis using a sample collected from 115 male Chinese university students. The results showed that the product terms of individualism and TPB factors were not able to significantly predict exercise intention after inclusion in the regression equation, nor were the product terms of collectivism and PBC (perceived behavior control) able to do so. However, the product terms of collectivism and attitude, as well as collectivism and SN (subjective norm) were able to significantly predict exercise intention when included in the regression equation. That is, horizontal and vertical collectivism can significantly moderate TPB constructs, primarily by moderating the relationship between attitude-exercise intention and SN-exercise intention. This study found that the predictive validity of exercise attitudes on exercise intentions in TPB constructs is greater only at low levels of horizontal and vertical collectivism and low at high levels. The predictive validity of SN is greater at high levels of horizontal and vertical collectivism and low in the inverse case. This research serves to enrich the theoretical framework for the theory of planned behavior and provides useful information for understanding university students’ exercise intentions and behaviors.

Although rings can move freely in all possible directions, by which they differ from all other apparatuses, physical performance at highest level is essetial in men’s artistic gymnastics to fulfill the exercise’s technical requirements in the interest of effective and accurate performance. We have aimed to compile the scientific evidence regarding exercises on the rings in men’s artistic gymnastics and, based on it, to investigate the necessary requirements for their successful realization. In regard to Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines, the database search (Google Scholar, PubMed, Web of Science and Research Gate) has identified 5759 potential studies. Original cross-sectional studies published between 2000 and 2022 written in English, active male gymnasts who do not suffer from injury as a sample of participants, and studies that have evaluated different types of elements on the rings were reconsidered. Lastly, 15 full-text studies were identified. A total of seven elements were evaluated, four strength elements (swallow, Azarian, iron cross and support scale), two dismounts (double backflip straight and double backflip straight with a 360◦ turn), and one swing element (backward giant swing). Two studies have conducted a dismount kinematic analysis, another four strength elements electromyography, while two studies have used force plates to evaluate the required specific strength for their successful performance. Hence, handgrip strength, pectoralis muscles, teres major, deltoids and serratus anterior are crucial. In addition, handgrip strength, proper swing movement, lateral arm movement during the descending phase, and hip flexor/extensor muscle activity are also essential for both giant swings and dismounts. Progressive strength upgrade of key movements in younger gymnasts is necessary to make successful generations on the rings. Therefore, in order to upgrade the above, researchers and scientists should discover a method for providing more relevant and updated information for practitioners, i.e., coaches and gymnasts.
尽管吊环可以在所有可能的方向上自由运动，这是它不同于其他器械的地方，但在男子艺术体操中，为了达到有效和准确的表演，达到最高水平的身体表现是必不可少的。本文旨在整理男子艺术体操吊环练习的科学依据，并在此基础上探讨其成功实现的必要条件。关于系统评价和荟萃分析(PRISMA)指南的首选报告项目，数据库搜索(Google Scholar, PubMed, Web of Science and Research Gate)已经确定了5759项潜在的研究。2000年至2022年间发表的原始横断面研究，以没有受伤的现役男子体操运动员为参与者样本，以及评估环上不同类型元素的研究，都被重新考虑。最后，确定了15项全文研究。总共评估了七个元素，四个力量元素(燕子，阿扎里安，铁十字和支撑尺度)，两个下马(双后空翻直和双后空翻直360度转身)，一个摇摆元素(向后巨大摆动)。两项研究进行了下马运动分析，另一项研究进行了四项力量元素肌电图分析，而两项研究使用了力板来评估他们成功表现所需的特定力量。因此，握力、胸肌、大圆肌、三角肌和前锯肌是至关重要的。此外，握力、适当的挥拍动作、下降阶段的侧臂运动和髋屈/伸肌活动对于巨大的挥拍和下马都是必不可少的。年轻体操运动员要想在吊环上取得成功，关键动作的力量逐步提升是必要的。因此，为了提升上述水平，研究人员和科学家应该找到一种方法，为实践者，即教练和体操运动员提供更相关和更新的信息。

This study aimed to compare lower limb strength disparities between male college volleyball and basketball players in four distinct vertical jump types. We recruited 100 second-level (above the national standard) male college athletes (50 basketball and 50 volleyball players) from Capital University of Physical Education and Sports who volunteered to participate. We assessed the performance of each athlete with regards to the squat jump (SJ), countermovement jump (CMJ), continuous jump with straight legs (CJs), and continuous jump with bent legs (CJb). Data analysis was performed by independent samples t-tests in SPSS version 25.0. software. In the CMJ test, volleyball players had a significantly higher vertical jump displacement (VJD; p = 0.047, t = −2.018), squat displacement (SD; p = 0.005, t = −2.883), peak force (p = 0.023, t = −1.964), and peak velocity (p = 0.011, t = −1.687) than basketball players. In the SJ test, volleyball players had a significantly higher VJD (p = 0.041, t = −1.21) and SD (p = 0.008, t = −1.46) than basketball players. In the CJs test, volleyball players had a significantly higher average vertical jump displacement (AVJD; p = 0.042, t = −2.067) than basketball players. In the CJb test, volleyball players had a significantly higher AVJD (p = 0.001, t = −3.448), average squat displacement (p = 0.017, t = −2.44), and average contact time (p = 0.045, t = −2.038) than basketball players. The overall vertical jump ability of college volleyball players was better than that of college basketball players. CMJ, SJ, CJs and CJb training should be included in daily training sessions and considered in the selection of basketball and volleyball players. In addition, coaches can use fast twitch Fibers, the effect of pre-stretch and k as the main evaluation indicators to assess daily training progress.
本研究旨在比较大学男子排球与篮球运动员在四种不同的垂直起跳类型中下肢力量的差异。我们从首都体育学院招募了100名二级以上(国家标准以上)男大学生运动员(篮球50名，排球50名)自愿参加。我们评估了每位运动员在深蹲跳(SJ)、反向跳(CMJ)、直腿连续跳(CJs)和屈腿连续跳(CJb)方面的表现。数据分析采用SPSS 25.0版独立样本t检验。软件在CMJ测试中，排球运动员的垂直跳跃位移(VJD)显著高于其他运动员;p = 0.047, t =−2.018)，深蹲位移(SD;P = 0.005, t =−2.883)、峰值力(P = 0.023, t =−1.964)和峰值速度(P = 0.011, t =−1.687)均高于篮球运动员。在SJ检验中，排球运动员的VJD (p = 0.041, t = - 1.21)和SD (p = 0.008, t = - 1.46)显著高于篮球运动员。在CJs测试中，排球运动员的平均垂直起跳位移(AVJD;P = 0.042, t =−2.067)高于篮球运动员。在CJb测试中，排球运动员的AVJD (p = 0.001, t =−3.448)、平均深蹲位移(p = 0.017, t =−2.44)和平均接触时间(p = 0.045, t =−2.038)显著高于篮球运动员。大学排球运动员的整体垂直起跳能力优于大学篮球运动员。将CMJ、SJ、cj、CJb训练纳入日常训练，并在篮球、排球运动员的选拔中予以考虑。此外，教练还可以将快缩纤维、预拉伸效果和k作为主要评价指标，来评估日常训练的进度。

Nocturia is a highly prevalent condition associated with poor quality of life and increased adverse health outcomes. Our study investigates the prevalent condition of nocturia and its profound impact on individuals’ quality of life and adverse health outcomes. We explore the correlation between nocturia and various comorbidities in a southeast Michigan population by analyzing data from 1023 participants who completed self-administered questionnaires during the 2021 Michigan Institute of Urology’s Men’s Health Event; 892 participants responded to the nocturia questionnaire. Categorizing participants based on the severity of nocturia into three groups—no nocturia, nocturia once per night, and multiple nocturia episodes per night—we employed Pearson’s Chi-square test to examine the relationship between nocturia severity and the presence of comorbidities. Our findings demonstrate significant associations between increasing episodes of nocturnal voids and the prevalence of hypertension, non-insulin-dependent diabetes and anxiety. Additionally, arthritis and colorectal polyps exhibit notable links with multiple nocturia episodes, while participants with a family history of hypertension show decreased prevalence as nocturnal voids increase, and a family history of myocardial infarction is notably associated with nocturia, particularly in the nocturia once per night group. Our research highlights the widespread impact of nocturia and its strong associations with diverse comorbidities, underscoring the importance of further investigation to comprehend the underlying mechanisms and enhance patient outcomes.

This study aimed to investigate the effect of Kinect-based mixed reality (KMR) exercise and unsupervised individual exercise on health-related fitness. A total of 27 participants underwent cardiorespiratory fitness tests for the inclusion criteria and were randomly assigned to three groups: a KMR group (KMRG), an unsupervised individual group (UIG), or a control group (CG). Pre and post-tests were conducted to measure Maximum oxygen uptake (VO₂max), body composition, upper and lower-body (LB) muscle strength, and endurance. KMRG and UIG attended exercise sessions 3 days per week for 8 weeks. KMRG used the KMR device and UIG used an instructive banner for exercise. All groups maintained their daily routines and submitted diet records every 4 weeks. Results showed that VO₂max, upper-body muscle endurance, and LB muscle endurance of knee extension was increased in KMRG and UIG. LB muscle strength in knee flexion was increased in UIG and LB muscle endurance in knee flexion was increased in KMRG. VO₂max, LB muscle strength, and LB muscle endurance were greater in KMRG than in CG. LB muscle strength in knee flexion was greater in KMRG than in UIG. Body fat was increased and skeletal muscle mass was decreased in CG. KMR exercise showed better performance than unsupervised individual (UI) exercise, and the exercise program was effective in both KMR and UI environments. These findings contribute to the growing evidence supporting the use of technology-based exercise interventions as a potential strategy to enhance health-related fitness.
