AbstractIn this study the stature, wingspan and stature-to-wingspan ratio (S:W) was recorded for N = 474 elite and international mixed martial arts (MMA) competitors who appeared in televised bouts over the course of one calendar year. Each weight division was split into three or four ranking groups (RG) depending on division size, as well as into groups depending on if the competitors had won or competed for a world title (El) or had done neither (In). One-way ANOVA (≤0.05) found that shorter competitors are ranked higher in flyweight and in the middle in women’s strawweight. Independent t-tests (≤0.05) found that shorter competitors also have more chance of winning or competing for a world title in featherweight and flyweight. Independent t-tests (≤0.05) also found a significant difference between males and female for S:W. There was a weak, negative correlation and a moderate, negative correlation between stature and rank in lightweight and light heavyweight respectively and a moderate, negative correlation between S:W and rank in featherweight. There were no other significant differences found. Overall, whilst MMA competitors have a S:W of 1:1.024, due to the paucity of significant differences found, it was determined that anthropometrical measurements cannot be used to predict success in elite and international mixed martial arts.

Background: Whilst most anthropometrical research within sport has focussed on muscle and fat distribution, more studies are measuring the relationship between stature and wingspan, which has been found to be selective criteria in many sports. Methods: In this study the stature, wingspan and stature-to-wingspan ratio (S:W) was recorded for N = 474 elite and international mixed martial arts (MMA) competitors who appeared in televised bouts over the course of one calendar year. Each weight division was split into three or four ranking groups (RG) depending on division size, as well as into groups depending on if the competitors had won a world title (Ch), competed for a world title (El) or had done neither (In). Results: One-way ANOVA (≤0.05) found that shorter competitors are ranked higher in flyweight and in the middle in women’s straw weight. Independent t-tests (≤0.05) found that shorter competitors also have more chance of winning or competing for a world title in featherweight and flyweight. Independent t-tests (≤0.05) also found a significant difference between males and female for S:W. There was a weak, negative correlation and a moderate, negative correlation between stature and rank in lightweight and light heavyweight respectively and a moderate, negative correlation between S:W and rank in featherweight. There were no other significant differences found. Discussion: Overall, whilst MMA competitors have a S:W of 1:1.024, due to the paucity of significant differences found, it was determined that anthropometrical measurements cannot be used to predict success in elite and international mixed martial arts.

Background:Old age is commonly viewed as a period of decreased physical activity,agitation and,increased calmness; depression or stress is not commonly acknowledged in the population. According to Erik Erikson, older adults experience Ego Integrity vs Despair, where people review their life cycle and accept it as something that had to be, resulting in wholeness or a sense of coherence. A lack of it would result in despair, where one's life is seen as being unproductive and guilt about the past, having not accomplished life goal leads to dissatisfaction and depression. Therefore,people with a poor sense of coherence could have higher levels of perceived stress and depression in them when compared to those who have a strong sense of coherence. Purpose: The study thus focuses on exploring the relationship between depression, perceived stress, and sense of coherence among the elderly population. Methods: Data was collected through the Sense of Coherence Scale,Perceived stress scale,and geriatric depression scale-15 from a sample of 40 from old age (people over 60 years). Out of which 20 were living in old age homes and 20 with their families.Statistical analyses were conducted using Pearson's Coefficient of Correlation and T-test.Results: There was a mild to moderate negative correlation between perceived stress and sense of coherence and a mild to moderate negative correlation between depression and sense of coherence. There was a significant difference in the levels of perceived stress and depression between people living in their homes and old age homes.

Background: Medical students face many changes when they entered higher education. These changes of learning occurred in competency-based curriculum compared to at high school learning such as approach of problem based learning and skills lab. The changes create anxiety for them. However, theoretically, anxiety decreases with longer exposure. The aims of this study were to find out the different of students’ anxiety status when they were at semester 1 and 2. It was also to find out the correlation between the length of study and anxiety level.Method: This was a descriptive study involving UNLAM medical students. 73 students were involved in this study at semester 1 and 88 students were involved in semester 2. Anxiety status was defined by using ADS questionnaire. Afterward the data were analyzed using Chi-square and Coefficient of Correlation at 95% level of confident.Results: There was 20 students (37.4%) experiencing anxiety at semester 1 and 11 students (12.5%) at semester 2, the different was statistically different (p=0.000). The correlation between the length of study and anxiety level was also statistically different (p=0.008), with very weak negative correlation (p=0.188).Conclusion: There is a significant difference of anxiety level among medical students at semester 1 and 2. There is also significantly negative correlation between anxiety level and the length of study on medical students.

The Relationship

Introduction. Today, there are not enough studies demonstrating the relationship between body composition disorders in men with excess adipose tissue and metabolic syndrome (MS), depending on the content of testosterone, estradiol, sex hormone binding globulin (SHBG), anthropometric parameters, or blood pressure (BP).Aim: to study the relationship between disturbances in anthropometric parameters, the level of sex hormones and BP in men with MS.Materials and Methods. The study included 64 overweight men. The patients were divided into 3 groups depending on the body mass index (BMI): group 1 with overweight (n = 24), group 2 with the first degree of obesity (n = 21), group 3 with the second and third degrees of obesity (n = 19). A correlation analysis was carried out between the results of bioimpedance analysis (BIA) and laboratory data, and the level of difference between the groups under consideration was determined.Results. The relationship was revealed between the parameters of body composition in men with overdeveloped adipose tissue and MS, depending on the level of testosterone, estradiol, SHBG, anthropometric parameters and blood pressure indicators. A moderate negative correlation was observed across the sample between the testosterone level and a number of anthropometric indicators: waist circumference (WC), OT/hip circumference (HC) and BMI (p < 0.05). A weak negative correlation was found between the level of testosterone, fat mass (FM) and the proportion of FM in the general sample. A weak negative correlation between SBP and testosterone across the sample found, while in group 3 – a moderate negative correlation. A positive weak correlation was found between testosterone and estradiol in the general sample and in group 2. In group 1, this correlation is moderately positive and in t group 3 – a negative weak correlation. A positive correlation can be traced between testosterone and SHBG: moderate in the entire sample, in groups 1 and 2, and noticeable in group 3.Conclusion. The relationship was revealed between the parameters of body composition in men with excess adipose tissue and MS, depending on the content of testosterone, estradiol, SHBG, anthropometric parameters and ВР. This confirms the consistency and multicomponent nature of the obesity problem.

The purpose of this study is to determine the levels of empathy for regularly exercising women and to determine whether empathy levels differ according to some variables.The study is planned as a single group pretest-posttest. 178 sedentary and healthy adult women participated in the study as a volunteer. Aerobic-Dance Exercise program was applied to the participants 60 minutes a day, 3 days per week for 8 weeks; then, The Empathic Tendency Scale (EQS) were filled at the beginning and at the end of the exercise program. The validity and reliability study of the scale was conducted by Dokmen (1988).Statistical Package for Social Sciences (SPSS) 16.00 software was used in the analysis of the data obtained from the research. One way ANOVA was used to determine the differences between the groups when the data showed normal distribution and after the homogeneity of the variances was tested, the Tukey test was used for differences between the groups and the error level was taken as 0.05.When the findings are examined; the mean score of " Empathic Tendency " according to the marital status, the study status and the number of children of the participants was statistically significant in the pretest-posttest after the exercise program (p<0.005). But, there was no statistically significant difference between the group's comparisons in terms of the “Empathic Tendency "(p>0.05). As a result, it was seen that exercise had a positive effect on the "Empathic Tendency” levels of the women participating in the study.

The purpose of this study was to examine the level of self-esteem, motivation, and anxiety of university English learners and their differences according to gender, year, English proficiency level, and KSAT level. This study further aimed to determine the correlation between self-esteem, motivation, and anxiety of the learners. The respondents of this study were 255 randomly selected college students enrolled in English classes from a local university. A survey questionnaire consisting of 43 items was administered to the students. The Mean was used to determine the level of students’ self-esteem, motivation, and anxiety, followed by t-test, ANOVA, and Pearson’s r analysis. The results showed that the students at the current school had a moderate level of self-esteem, motivation, and anxiety. Significant differences were found in the students’ level of self-esteem, motivation, and anxiety when they were grouped according to gender and English proficiency level. The males had higher level of self-esteem and motivation and lower level of anxiety when compared with the females. No significant difference existed when the students were grouped according to year. There was a positive correlation between self-esteem and motivation, with high levels of self-esteem associated with high levels of motivation. On the other hand, there was a strong, negative correlation between self-esteem and anxiety with high levels of self-esteem associated with low levels of anxiety. Furthermore, there was a moderate, negative correlation between motivation and anxiety, with high levels of motivation associated with low levels of anxiety.

Abstract Objectives The aim of this study was to evaluate the resilience of girls with central precocious puberty (CPP) during treatment with a gonadotropin-releasing hormone agonist (GnRHa) and compare these results with their healthy peers. Methods The Connor–Davidson Resilience Scale (CD-RISC) is a self-report scale used to quantify resilience, which is divided into seven subgroups (hardiness, coping, flexibility, purpose, optimism, regulation of emotion and cognition (REC), and self-efficacy). Fifty-one girls with CPP receiving GnRHa treatment and 51 healthy controls were involved in the study. Anthropometric measurements were evaluated and CD-RISC was performed at least six months after the initiation of GnRHa treatment. Results There was no statistically significant difference between the anthropometric evaluations of girls with CPP and the control group. Similarly, the total score and subgroup scores of patients with CPP and the control group showed no statistically significant difference. In the correlation analysis, there was a weak negative correlation between height and flexibility (r=−0.314 p=0.025), height SDS and flexibility (r=−0.254 p=0.092), height SDS, and purpose (r=−0.285 p=0.058). Also, there was a weak negative correlation between REC and weight (r=−0.435 p=0.003), REC and weight SDS (r=−0.461 p=0.002), REC and height (r=−0.269 p=0.077), REC and height SDS (r=−0.322 p=0.033), REC and BMI (r=−0.289 p=0.058), and REC and BMI SDS (r=−0.353 p=0.019). Conclusions The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers. The early diagnosis of the disease and adequate treatment may decrease the discrepancy of somatic changes between girls with CPP and their peers, which may help them to overcome the stress of CPP and long-term treatment.
