The aim of this study was to evaluate the relationship between the strength and jump parameters of elite level badminton players in the range oscoref 5, 10, and 15 intervals of smash. A total of 10 male national badminton players with a mean age of 15.2 ± 0.18 years, length of 170.5 ± 2.13 cm, body weight of 59.5 ± 2.48 kg and sports age of 5 ± 1.36 years participated in the study. Leg strength test dynamometer (Prosport-TMR HBD 1000 dynamometer), jump parameters of the subjects were measured with Opto Jump (Microgate, Bolzano). The smash swere performed as 3x30 sec and 3 minutes passive rest protocol was applied after each series. In every 30 seconds, the shots were made by the national team coach with the multishuttle method as 5-10-15. The hit of the parallel smash scored was recorded by the referee. Data analysis was performed using SPSS 23.0 package program. For the relationship between the parameters, Spearman Correlation test and Friedman test were used for comparison of parameters with intermittent jump. As a result of the study, it was seen that there were statistically significant differences in the power and contact time parameters applied during the jumps as the number of smash increased within 30 seconds. In addition, it was found that as the frequency of scored increased, the rate of accuracy and heart rate (KAS) increased. This can be interpreted as a decrease in the scored of the players due to fatigue as the smash frequency increases. ​Extended English summary is in the end of Full Text PDF (TURKISH) file. Özet Bu çalışma elit seviyedeki badmintoncuların 30 sn içinde yaptıkları 5,10 ve 15 aralıklı smaç vuruşu atış performanslarının kuvvet ve sıçrama parametreleri ile ilişkilerinin değerlendirilmesi amacıyla yapılmıştır. Çalışmaya Ankara Büyükşehir Belediyesi ve Ego Spor Kulübü yaş ortalaması 15.2±0.18 yıl, boy uzunluğu 170.5±2.13 cm, vücut ağırlığı 59.5±2.48 kg ve spor yaşı 5±1.36 yıl olan toplam 10 erkek milli badmintoncu katılmıştır. Araştırmaya katılan deneklerin bacak kuvveti testi dinamometre (Prosport- TMR HBD 1000 dinamometre), sıçrama yükseklikleri ve havada kalış süreleri Opto Jump (Microgate, Bolzano) cihazı ile ölçülmüştür. Smaç vuruşları 3x30 sn şeklinde yapılmış ve her seri sonrası 3 dk pasif dinlenme protokolü uygulanmıştır. Her bir 30 sn ‘de atışlar 5-10-15 şeklinde milli takım antrenörü tarafından top besleme yöntemi ile yapılmıştır. Paralele atılan smaç vuruşlarının isabeti ise hakem tarafından kaydedilmiştir. Verilerin analizi SPSS 23.0 paket programında yapılmıştır. Parametreler arasında ilişki için, Spearman Korelasyon test ve aralıklı sıçrama ile parametrelerin karşılaştırılmasında Friedman test uygulandı. İstatiksel olarak anlamlılık düzeyi p<0.05 olarak kabul edilmiştir. Araştırmanın sonucunda 30 sn içinde yapılan atış sayısı arttıkça sıçramalar sırasında uygulanan power ve contact time parametrelerinde istatistiksel olarak anlamlı farklılıklar olduğu görülmüştür. Bunun yanı sıra atış sıklığı arttıkça isabet oranlarında azalma ve kalp atım sayısında (KAS) artış olduğu tespit edilmiştir. Bu durum atış sıklığı arttıkça oluşan yorgunluk sebebiyle, oyuncuların isabet oranlarında bir azalmaya sebep olabileceği şeklinde yorumlanabilir.

Background: Previous studies have examined the relationship between external training load and creatine kinase (CK) response after soccer matches in adults. This study aimed to build training- and match-specific CK prediction models for elite youth national team soccer players. Hypothesis: Training and match load will have different effects on the CK response of elite youth soccer players, and there will be position-specific differences in the most influential external and internal load parameters on the CK response. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: Forty-one U16-U17 youth national team soccer players were measured over an 18-month period. Training and match load were monitored with global positioning system devices. Individual CK values were measured from whole blood every morning in training camps. The dataset consisted of 1563 data points. Clustered prediction models were used to examine the relationship between external/internal load and consecutive CK changes. Clusters were built based on the playing position and activity type. The performance of the linear regression models was described by the R2 and the root-mean-square error (RMSE, U/L for CK values). Results: The prediction models fitted similarly during games and training sessions ( R2 = 0.38-0.88 vs 0.6-0.77), but there were large differences based on playing positions. In contrast, the accuracy of the models was better during training sessions (RMSE = 81-135 vs 79-209 U/L). Position-specific differences were also found in the external and internal load parameters, which best explained the CK changes. Conclusion: The relationship between external/internal load parameters and CK changes are position specific and might depend on the type of session (training or match). Morning CK values also contributed to the next day’s CK values. Clinical Relevance: The relationship between position-specific external/internal load and CK changes can be used to individualize postmatch recovery strategies and weekly training periodization with a view to optimize match performance.

This study evaluated the relationship between leg strength and endurance run performance, independent of aerobic capacity (V̇O2peak), body size, and gender, in children and adolescents with mild or moderate mental retardation. Twenty-six individuals (15 boys and 11 girls) volunteered and underwent tests of V̇O2peak, isokinetic leg strength, and endurance run performance (600-yard ran/walk and 20-m shuttle run). Results showed that leg strength was significantly related to both types of run performance; however, when controlling for V̇O2peak, body size, and gender, leg strength was a more significant contributor to the 600-yard run/walk than to 20-m shuttle run performance. Gender did not influence these relationships. These data suggest that leg strength has a significant influence on endurance run performance in children and adolescents with mild or moderate mental retardation.

Objective: This study was conducted to investigate the relationship between perceived insufficient milk and breastfeeding self-efficacy levels among Turkish mothers. Methods: The study was conducted on 200 mothers whose infants were hospitalized and under treatment and who could breastfeed their infants in the newborn clinic of a university hospital in eastern Turkey between June 2013 and February 2014. A sampling method was not applied in the study, so the sample consisted of the population of the study. The ‘Personal Information Form’, ‘Breastfeeding Self-Efficacy Scale’ and ‘Perception of Insufficient Milk Questionnaire’ were used to collect the data. Data were analysed by using percentage distribution and arithmetic average; independent sample t test, Mann–Whitney U test, Kruskal–Wallis variance analysis, Pearson correlation analysis and Cronbach alpha reliability coefficiency in the SPSS 18.0 package program. Results: The study determined that advanced age, higher education level and higher income status, male gender of the child, planning of the pregnancy, many births, receiving breastfeeding education and the length of time that mothers planned to exclusively breastfeed affected breastfeeding self-efficacy and perception of milk sufficiency positively ( p<0.05). The study showed that, as breastfeeding self-efficacy levels of mothers increased, their perception of milk sufficiency also increased ( p<0.05). Conclusion: The study concluded that some factors related to the mother, infant, pregnancy and breastfeeding affected breastfeeding self-efficacy and the perception of milk insufficiency. As the breastfeeding self-efficacy level increased, the milk was perceived to be more sufficient.
