This study was conducted to compare different variables of social self-efficacy (SSE) as determinants for adolescents in selecting and taking part in team and individual sports. Four sporting codes were selected for study: table tennis, swimming, handball, and basketball. Participants were 100 adolescents who had played their chosen sport for an average of 5.4 years. Results showed that the difference in SSE between those playing table tennis and those playing handball was significant, as was the difference between those playing table tennis and those playing basketball, swimming and handball, swimming and basketball. No statistical difference was found in SSE between those playing table tennis and those involved in swimming, and handball and basketball. Likewise, there was no statistically significant difference between SSE scores according to gender for any of the sports. Nor was there any significant difference between the socioeconomic status (SES) of the participants according to the sport they played and the arithmetic average of their SSE scores. A negative correlation was noted (p > .05) between the sporting code and the SES of participants.

Abstract Background The incidence of chronic kidney disease (CKD) increases each year, and obesity is an important risk factor for CKD. The main anthropometric indicators currently reflecting obesity are body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR), but the rationality and merits of various indicators vary. This article aims to find whether the WHtR is a more suitable physical measurement that can predict CKD. Methods Pubmed, embase, the cochrane library, and web of science were systematically searched for articles published between 1998 and 2019 screening CKD through physical indicators. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and evaluated the quality of the methodology included in the study. Meta-analysis used the Stata 12.0 software. Results Nine studies were included, with a total of 202,283 subjects. Meta-analysis showed that according to the analysis of different genders in 6 studies, regardless of sex, WHtR was the area with the largest area under the curve (AUC). Except WHtR and visceral fat index (VFI) in women which showed no statistical difference, WHtR and other indicators were statistically different. In three studies without gender-based stratification, the area under the curve AUC for WHtR remained the largest, but only the difference between WHtR and BMI was statistically significant. When the Chinese population was considered as a subgroup, the area under the curve AUC for WHtR was the largest. Except for WHtR and VFI which showed no statistical difference in women, there was a statistically significant difference between WHtR and other indicators in men and women. Conclusion WHtR could be better prediction for CKD relative to other physical measurements. It also requires higher-quality prospective studies to verify the clinical application of WHtR.

ABSTRACT The relative age effect (RAE) refers to the oversampling of youth born in the first quarter of the birth year when auditioning for selected age-restricted sports. This advantage conferred to the older athlete is the result of the older athlete being more physically and emotionally mature and, therefore, assumed to be a more advanced player. Chosen players will be exposed to better coaching, competition, teammates, and facilities in their respective sport. This RAE was first described in 1988 for ice hockey, and has since been described in numerous other sports, with a vast majority of the literature demonstrating an RAE in small cohorts, as well as in team sports and sports that incorporate a ball (i.e. soccer, basketball, hockey, etc). We extended the exploration of an RAE beyond specific sports by examining the birth quarter of over 44,000 Olympic athletes birth dates, born between 1964 and 1996. Our hypothesis is that not only did an RAE exist in Olympic athletes, but that it existed across selected categories of athletes (by gender), such as team vs individual sports, winter vs summer athletes, and sports using a ball vs those not using a ball. The fractions of births in the first vs the fourth quarter of the year were significantly different (p < 0.001) from each other for the summer and winter Olympians, ball and nonball sports, and team as well as individual sports. This significant difference was not gender specific. We found the general existence of an RAE in Olympic athletes regardless of global classification.

The first technique that starts the match in volleyball is service. It has been known that benefiting efficiently from the service as the first hitting attack in each period of the match is remarkable. However, it has also been emphasized in the study carried out by Marcelino et al. that managing the scores especially at the end of the set and match are more important for the trainers and players. For that reason, it is considered that trainers’ including target-specific service work-outs in training programs will be the most remarkable factor for winning the game (Marcelino, Sampaio et al., 2012)The purpose of this study was to examine the change of service efficiency after the 20th scores according to nationality and positions in 2017-2018 Volleyball Sultanlar League session. Into the study, totally 134 female players including natives (n=94) and foreigners (n=40) from 12 teams between 26 and 30 years old (28.25±1,62) were included. The numbers of the services performed after the 20th scores of 17.918 rallies in 496 sets (except from the 5th set) of 125 matches played by 12 teams during the session were evaluated. All matches were recorded with a video recorder by the researcher, and the videos were analyzed by the experts in 3 repetitions. The service error, service as the free ball, bad service, good service, service ace and total number of service after the 20th scores during the match were recorded in numbers. Lilliefors Kolmogorov-Smirnov Test indicated whether the study data were appropriate for the normal distribution or not (p<.05). In data analysis, descriptive statistics such as number, percentage, arithmetic average and standard deviation were used; and Independent Samples T-Test and One-Way Variance Analysis (One-Way ANOVA) were used for determining the difference between dependent and independent variables. While interpreting the data, 0.01 and 0.05 were accepted as the level of significance. The research data were analyzed using SPSS 21 statistical software.As result of the findings obtained at the end of the study, it was determined that there were significant differences except from the service as the free ball in terms of the Turkish players and foreign-national players (p<0.05). No significant difference was noticed in terms of service error, service as the free ball, bad service, good service, service ace and total number of service after the 20th scores during the session depending upon the positions of the players (p>.05). As a result, it is determined that foreign players serve more effectively than native players at 20th points which is named as golden points.Extended English summary is in the end of Full Text PDF (TURKISH) file.ÖzetVoleybolda müsabakayı başlatan ilk teknik servistir. İlk hücum vuruşu olan servisi müsabakanın her periyodunda etkin kullanmanın önemli olduğu bilinmektedir. Ancak özellikle setin ve maçın son bölümlerindeki sayıların yönetiminin antrenörler ve sporcular için daha önemli olduğu Marcelino ve arkadaşlarının yapmış olduğu çalışmada da vurgulanmıştır.   Bu nedenle antrenörler antrenman programlarında hedefe yönelik etkin servis çalışmalarına yer vererek maçı kazanmada en önemli etken olacağı düşünülmektedir (Marcelino, Sampaio et al. 2012)Bu çalışmanın amacı, 2017-2018 voleybol Süper lig sezonunda 20. sayılar sonrası atılan servis etkinliğinin uyruk ve mevkilere göre değişikliğinin incelenmesidir. Çalışmaya 26-30 yaş arası (28.25±1,62) 12 takımdan yerli (n=94), yabancı (n=40) toplam 134 kadın oyuncu dahil edilmiştir. Sezon içerisinde 12 takımın mücadele ettiği 125 maç da (5. set hariç) 496 set 17.918 rallinin 20. sayılar sonrası atılan servis sayıları değerlendirilmiştir. Bütün maçlar araştırmacı tarafından video kamera ile kayıt altına alınmış, videolar uzman kişiler tarafından 3 tekrar ile analiz edilmiştir. Müsabaka esnasındaki 20. sayılardan sonra yaptıkları servis hatası, avantaj top olarak dönen servis, kötü servis, iyi servis, servis ace ile toplam servis sayıları adet cinsinden kaydedilmiştir. Değişkenlerin normal dağılıma uygunluğu Lilliefors Kolmogorov-Smirnov testi çalışma verilerinin normal dağılıma uygun olmadığını göstermiştir (p<.05). Verilerin analizinde; tanımlayıcı istatistikler (sayı, yüzde, aritmetik ortalama ve standart sapma) ile bağımlı ve bağımsız değişkenler arasındaki farklılığı saptamak amacıyla; Bağımsız Gruplar için t Testi ve Tek Yönlü Varyans Analizi (One-Way-Anova) kullanılmıştır. Verilerin yorumlanmasında 0.01 ve 0.05 anlamlılık düzeyi kullanılmıştır. Araştırma verileri SPSS 21 programı ile analiz edilmiştir. Elde edilen bulgular sonucunda; Türk sporcular ile yabancı uyruklu sporcuların avantaj olarak dönen servis sayıları hariç anlamlı farklar tespit edilmiştir (p>.05). Sonuç olarak; yabancı uyruklu sporcuların, altın sayılar olarak da adlandırılan 20. Sayılarıda, yerli oyunculardan daha etkin servis attığı belirlenmiştir.

Objective: To analyze chronotype, duration and quality of sleep among elite athletes, to compare differences in sleep variables between sex, and to compare differences between athletes of individual and team sports. Method: The sample included 70 Brazilian elite athletes of both sex (male=37; female=33) with a mean age 23.0 ± 4.0 years old. To measure sleep-wake cycle, athletes wore an actigraph on the wrist for 10 days. Moreover, athletes answered the chronotype questionnaire of Horne and Östberg. Results: The most athletes are intermediate-type (n=55, 78.6%), with a mean of 07h:18min of sleep per night. The athletes demonstrated higher sleep fragmentation (39.26 ± 23.66 minutes) and higher sleep latency (30.88 ± 16.19 minutes) during pre-competition training days. Additionally, the athletes of individual sports demonstrated more fragmentation (p<0.001) and less sleep efficiency (p<0.001) compared athletes of team sports. However, there was no significant difference in all sleep variables between the male and female sex. Conclusion: The overall elite athletes presented poor sleep quality during the training periods prior to the Rio 2016 Olympic Games, and individual athletes showed higher fragmentation and poorer sleep efficiency compared to team athletes.

Background: Youth sports specialization has become more prevalent despite consequences such as increased injury rates and burnout. Young athletes, coaches, and parents continue to have misconceptions about the necessity of sports specialization, giving athletes the encouragement to focus on a single sport at a younger age. Purpose: To characterize the motivations for specialization and determine when elite athletes in various individual and team sports made the decision to specialize. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A Likert-style survey was developed and distributed to athletes from two National Collegiate Athletic Association (NCAA) Division I institutions. The survey’s Flesch-Kincaid grade level was 6.3. Statistical analysis was performed via the Student t test, where a P value less than .05 was considered significant. Results: A total of 303 athletes with a mean ± SD age of 19.9 ± 1.52 years across 19 sports were surveyed; 94.7% of specialized athletes had previously played another organized sport prior to college, and 45% of athletes had played multiple sports up to age 16 years. The mean age of specialization was 14.9 years, with a significant difference between athletes competing in team (15.5 years) and individual (14.0 years) sports ( P = .008). Males in individual sports specialized earlier than those in team sports ( P ≤ .001). Nearly one-fifth (17.4%) of athletes reported specializing at age 12 years or earlier. Personal interest, skill level, time constraints, and potential scholarships were the most important reasons for specialization overall. For individual sports, the motivations for specialization were similar, but collegiate ( P < .001) or professional ( P < .001) ambitions were significantly larger contributing factors. Conclusion: Early sports specialization is uncommon among NCAA Division I athletes for most team sports, whereas individual sports tend to have athletes who specialize earlier and are more motivated by professional and collegiate goals. This study characterized the timing of specialization among elite athletes, providing a basis for understanding the motivations behind youth sports specialization. Physicians should be prepared to discuss the misconception that early sports specialization is necessary or common among most team-focused collegiate-level athletes. Knowing the motivations for sports specialization will guide clinicians in their discussions with youth athletes.

The aim of the study was to determine and compare the reactive agility league players and players of regional competitions and its changes due to sport-specific warm-up. The research sample consisted of 43 players, who were divided into two groups. First group consisted of 22 players from teams playing in the national league competitions (24.3 ± 5.6 years, body height 179.4 ± 8 cm, body weight 74.8 ± 10.4 kg), the second group of 21 players playing lower regional competitions (26.7 ± 5.64 years, body height 180.2 ± 7.7 cm, body weight 77.8 ± 10.5 kg). We used Fitro agility test modified for table tennis before and after warm-up. For data analysis was used two-way ANOVA with repeated measures. When comparing reactive agility, we found significant difference before and after the sport-specific warm-up for group of league players (885.94 ± 122.69 ms before the warm-up, 842.80 ± 119.48 ms after the warm-up, an improvement of 4.87 %, p <0.0004) and also for the group of players from lower competitions (932.96 ± 114.78ms before the warm-up, 871.90 ± 119.68 ms after the warm-up, an improvement of 6.54 %, p < 0.0002). Although league players achieved better results, the difference between the groups was found not significant. The nonsignificant statistic values for interaction indicates, that league players did not respond to the sport-specific warm-up differently than players from lower competitions. Sport-specific warm-up is important for improving the reactive agility and therefore should not be underestimated.
