Effects of Multiple Sprint Test on Average Speed and Exercise Heart Rate in Amateur Soccer Players

The purpose of this study is to investigate the effects of multiple sprints on average speed and exercise heart rate of U18 female and U18 male amateur soccer players. In this study, totally 42 amateur soccer players including U18 (n= 21) and U18 (n=21) players performed 7 repetitive sprints of 34.2 meters with a 25 seconds jog of 50 meters distance. During exercise and recovery period, heart rate per minute was recorded by Polar Heart Rate Telemetry. In statistical analyzes, t-tests were used in two groups comparisons, while the effects of other variables on average speed and cardiovascular parameters were determined by two way analyzes of variance.Results of this study, U18 male players’ average speed of 5.14 m/ sec is higher than the U18 female players’ average speed of 4.62 m/sec. The physical characteristics of U18 male and U18 female amateur soccer players were different in favors of the U18 male players, and that gender was significantly effective on the average speed rather than the number of sprints.  Heart rate per minute has continually increased in different characteristics at the start, finish and recovery periods of the sprints until the finish of the seventh sprint in both amateur U18 male and U18 female. It found increase in the Sprint time were as follows; U18 female 0.40 sec and U18 male 0.20 second. Decrease in the average speed was U18 female 0.28 sec., and U18 male 0.15 second.Conclusion, in multiple speed tests, maximum and average speed of the U18 amateur female and male soccer players, the decrease rate in their speed and their cardiovascular responses show differences. In U18 Amateur, males seem to be faster and have the ability of keeping speed at a high level, and the ability of intensity and recovery in maximal level in a short time than the females.  In the Bangsbo test, the recovery time in men should be less than 25 seconds

Örgütsel Bağlılığın Tükenmişlik İle İlişkisi: Öğretmenler Üzerine Bir Araştırma

Günümüzde insan faktörünün örgütsel bağlamdaki rolünün artmasıyla birlikte, çalışan ile örgüt arasındaki uyumun bir göstergesi olan örgütsel bağlılık kavramının giderek önem kazandığıgörülmektedir. Bununla birlikte, modern çağın ortaya çıkardığısürekli değişim ve belirsizlik ortamı, çalışan ile örgüt arasındaki uyumlu ilişkiyi etkileyerek, tükenmişlik kavramının bu süreçteki rolünün dikkate alınmasınıadeta zorunlu kılmaktadır. Bu doğrultuda çalışanların örgütsel bağlılık duygularıyla tükenmişlik duygularıarasındaki ilişkilerin ortaya çıkarılmasıve irdelenmesi gerekmektedir. Bu çalışmada Allen ve Meyer 1990 tarafından ortaya konan örgütsel bağlılık boyutlarıile Maslach ve Jackson 1981 tarafından geliştirilen tükenmişlik boyutlarıarasındaki ilişkinin araştırılmasıamaçlanmıştır. Araştırmanın örneklemi 13 ayrıilköğretim okulunda görevli ve yaşaralığı22 ile 64 arasında değişen toplam 349 öğretmenden oluşmaktadır. Araştırmada örgütsel bağlılık ve tükenmişlik boyutlarıarasındaki ilişkilerin incelenmesi için anket yöntemi kullanılmışolup, Allen ve Meyer Örgütsel Bağlılık Ölçeği ve Maslach Tükenmişlik Envanteri ile elde edilen veriler SPSS 15.0 ve LISREL 8.30 istatistik programlarıkullanılarak analiz edilmiştir. Araştırma sonunda elde edilen bulgular, örgütsel bağlılık boyutlarıve tükenmişlik boyutlarıarasında çeşitli seviyelerde anlamlıilişkilerin olduğunu göstermiştir. Özellikle duygusal bağlılığın, tükenmişlik boyutlarından duygusal tükenme, duyarsızlaşma ve kişisel başarıhissi azalmasını; devam bağlılığının ise, duygusal tükenme, duyarsızlaşma ve kişisel başarıhissi azalmasınıyordadığıbelirlenmiştir. Diğer taraftan, normatif bağlılığın, tükenmişlik boyutlarından sadece duygusal tükenme boyutu üzerinde yordama becerisine sahip olduğu ortaya çıkmıştır. Tüm bu bulgular tükenmişlik boyutlarının açıklanmasında örgütsel bağlılık değişkeninin önemli etkileri olduğunu göstermişve çalışma sonucunda elde edilen tüm bu bulgular ilgili yazında yapılan çeşitli çalışmalardaki bulgular ışığında tartışılmıştır

Influencia de un injerto en el perfil de ácidos grasos y algunas propiedades fisicoquímicas de la semilla y el aceite de semillas de sandía

This study aimed to investigate the effects of grafting on the fatty acid profile and some physicochemical properties of watermelon seed and seed oil. The ‘Crimson Tide’ cultivar was used as the scion while two wild watermelon (Citrullus lanatus var. citroides (A1 and A2)), one Lagenaria siceraria (A3) and one Cucurbita maxima Duchesne x Cucurbita moschata Duchesne (A4) were used as rootstocks. The use of rootstock significantly influenced the fatty acid profile and the physical parameters of seeds and seed oils. The highest linoleic acid ratio was found in the seed oil from A1 and A2, the oil from A3 had the highest oleic acid ratio. The results showed that the content and acid value in seed oils were improved, and that total phenolic compounds and antioxidant activity of both seed and oil were decreased by grafting. Wild rootstocks can be used in watermelon cultivation to obtain a watermelon seed which is rich in linoleic acid.El objetivo de este estudio fue investigar los efectos del injerto en el perfil de ácidos grasos y algunas propiedades fisicoquímicas de la semilla y el aceite de semillas de sandía. El cultivar ‘Crimson Tide’ se utilizó como vástago, mientras que dos sandías silvestres (Citrullus lanatus var. Citroides (A1 y A2)), una Lagenaria siceraria (A3) y una Cucurbita maxima Duchesne x Cucurbita moschata Duchesne (A4) se utilizaron como portainjertos. El uso de portainjertos influyó significativamente en el perfil de ácidos grasos y los parámetros físicos de semillas y aceites de semillas. La proporción de ácido linoleico más alta se encontró en el aceite de semillas de A1 y A2, el aceite de A3 tuvo la proporción de ácido oleico más alta. Los resultados mostraron que el contenido de aceite y el índice de acidez mejoró y los compuestos fenólicos totales y la actividad antioxidante tanto de la semilla como del aceite se redujeron mediante el injerto. Para obtener un aceite de semillas de sandía rico en ácido linoleico, se pueden utilizar portainjertos silvestres en el cultivo de sandía

The Effects of Pilates and Aerobic Exercise on Blood Pressure, Heart Rates, and Blood Serum Lipids in Sedentary Females

The aim of this study was to determinate the effects of 12 weeks pilates and aerobic exercise on blood pressure, heart rates, and blood serum lipids in sedentary females. 18 sedentary women with an average age of 45.52 years, height of 161.14 cm and weight of 72.5 kg have been selected and put through a plates and aerobic exercise programmer one hour a day for three days a week. Exercises in each training session were arranged in such a way as to make each woman’s heart rate to reach a level of 130-140 a minute. The waist and hip circumferences were measured using a measuring tape. BMI and waist hip ratio were calculated by standard formulas. Triglyceride (TG), Total Cholesterol (TC), High density lipoprotein (HDL-C) and Low density lipoprotein (LDL-C) levels were determined by Hitachi 717 auto analyzer. Analysis was performed on SPSS 21 version. Paired-t tests were done statistical analysis. Body Weight found before 12 weeks plates and aerobic exercise 72.5 kg and after 63.8 kg. At the end of the 12 weeks exercise program, a decrease of %12.00 in body weight, %14.03 in systolic, %3.96 in diastolic, %13.85 in cholesterol, %25.30 in Triglyceride, and %22.33 in LDL-C have been registered. However, there were increases of %16.34 in HDL-C. The effects of aerobic exercise is on Triglyceride, HDL-C, LDL-C and total cholesterol since (p<0.01). At the end of the 12 weeks exercise program, a decrease %13.34 hip circumference and %4.19 waist circumference. Waist to hip ratio found before 12 weeks plates and aerobic exercise 0.87 cm and after 0.78 cm. The effects of aerobic exercise is on Body weight, Systolic blood pressure, Heart rate, hip and waist circumference since (p<0.05; p<0.01). In this study, together Pilates and aerobic exercise was effective in sedentary women with initially high total cholesterol, triglyceride, and Low density lipoprotein levels. At end of the cycles of 12 weeks Pilates and aerobic exercises, has a positive effect of waist to hip ratio, blood pressure, and heart beats in sedentary females. Risk of heart and vascular disease is reduced. Pilates and aerobic exercises are recommended for decrease risk

Block Updates on Truncated ULV Decomposition

AIRCC Publishing Corporation;CSITC;HAVELSAN;KTD3rd International Conference on Computational Science, Engineering and Information Technology, CCSEIT 2013 -- 7 June 2013 through 9 June 2013 -- Konya -- 98896A truncated ULV decomposition (TULV) of an m×n matrix X of rank k is a decomposition of the form X = U1LV T 1 + E, where U1 and V1 are left orthogonal matrices, L is a k × k non-singular lower triangular matrix and E is an error matrix. Only U1, V1, L, and ?E?F are stored. We propose algorithms for block updating the TULV based upon Block Classical Gram-Schmidt that in [4]. We also use a refinement algorithm that reduces ?E?F, detects rank degeneracy, corrects it and sharpens the approximation. © Springer International Publishing Switzerland 2013
