This study aims to observe the possible negative effects that might occur on bio-chemistry and hemogram values of tennis players during the intense competition period by comparing the blood values of pre-competition period with 10 days of intense exercise. Blood samples were obtained from tennis team players who do not have any specific health problems and who study in university and regularly exercise. Mean age of the athletes are 22,40 ± 3,20 years and mean height is 179,83 ± 7,57 cm. This study is performed with 14 volunteer tennis players. Blood samples are obtained during the first day of the intense exercise program after the exercise, last day of the exercises and also right after the exercises. As per the obtained data, descriptive statistics are run (mean and standard deviation) and in order to compare the values of before and after the 10 days of intense exercise, Wilcoxon two related sample test was used. As per the results of the blood tests from before and after the exercise period, it is seen that values such as AST, ALT, MCH, MCHC and CK showed statistical significance (P<0.05). The athletes who prepared for the competitions with these values showed positive increases in bio-chemistry and hemogram values.

Bu çalışmanın amacı; Türkiye Güreş Federasyonunda görev yapan antrenörlerin sağlıklı yaşam biçimi davranışlarının incelenmesidir. Araştırmanın evrenini Türkiye Güreş Federasyonunda görev yapan antrenörler oluştururken; örneklemini Nisan 2015 yılında Elazığ ve Sivas ilinde yapılan Yıldızlar Türkiye şampiyonası (Serbest-Grekoromen)'nda görevli olan toplamda 100 Erkek Antrenör oluşturmuştur. Araştırmada, Sağlıklı Yaşam Biçimi Davranışlarının incelenmesine yönelik "Sağlıklı Yaşam Biçimi Davranışları Ölçeği II" kullanılmıştır. Araştırmada elde edilmiş olan veriler SPSS 17 paket programı ile analizleri yapılmıştır. Farklılıkları belirlemek için One Way Anova ve Independent t testi yapılmıştır. Araştırmada yer alan antrenörlerin SYBD ölçeği genel ortalaması 142.36±16.0 puan (min:98, max:169) olarak tespit edilmiştir. Sağlık durumunun iyileştirilmesine katkı sağlayan davranışlar içerisinde en yüksek puan ortalamaları sırasıyla manevi gelişim, kişilerarası iletişim, , en düşük ortalama ise sağlık sorumluluğu, stres yönetimi ve destek, egzersiz ve beslenme alışkanlığına aittir. Sigara kullanmayanların sigara kullananlara göre, düzenli spor yapanların spor yapmayanlara göre ortalamalarının daha yüksek olduğu tespit edilmiş olup istatiksel olarak anlamlı bir sonuç görülmüştür. Yaş, kademe, görev süresi, bakımından SYBD'da istatistiksel olarak anlamlı bir farklılık bulunmadığı tespit edilirken; bunun yanında, düzenli olarak spor yapanların spor yapmayanlara göre beslenme düzeylerinin yüksek olduğu tespit edilmiştir. Sonuç olarak; Güreş Federasyonunda görev yapan antrenörlerin SYBD orta seviyede olduğu görülmüştür. SYBD'nın kavranması ve günlük hayatta uygulanabilmesi için konu ile ilgili düzenlenecek sempozyumlar ve eğitim seminerlerinin antrenörlere faydalı olacağı söylenebilir.

Background and Study Aim. This study investigated the effects of HIIT (high-intensity interval training) implementations on some serum elements, resting heart rate, total body weight, and BMI parameters in tennis players. Material and Methods. The study group consisted of 20 athletes (aged 18-22) who were actively playing tennis. The athletes were divided into experimental (n=10) and control (n=10) group. To assign participants to these groups homogeneously, preliminary measurements were made before the study, and the results were used for clustering analysis. While the control group continued their regular tennis training, the experimental group was given additional HIIT three days a week besides regular tennis training. Measurements of BMI, resting heart rate, and body weight were taken, and serum samples were collected before and after training from both groups. The SPSS package program was used in data analysis. The level of significance was set at p<0.05 in the tests. Participants showed significant differences in sodium, calcium, iron, resting heart rate, weight, and BMI parameters between groups (p<0.05). Results. However, no significant differences between the groups were found in potassium, chlorine, and magnesium parameters (p>0.05). The within-group measurements of sodium, calcium, resting heart rate, weight and BMI levels decreased in the experimental group in the post-test, while iron levels were higher in the post-test compared to the pre-test value (p<0.05). On the other hand, the pre-test and post-test values were similar within the control group, and there were no significant differences (p>0.05). Conclusions. Training remodelled with HIIT implementation can affect athletes' element levels, BMI, total body weight, and resting heart rate. In addition, the increase in iron levels due to HIIT in the experimental group was important. We believe that this may affect both muscle contraction functions and the efficiency performance output. Lastly, due to the decrease of calcium and sodium elements with HIIT implementations, we suggest that HIIT applications should not be performed unsupervised. In addition, by tracking the element levels of athletes, they should be supported with supplements or nutritional meals in line with expert advice when necessary.

Purpose: The aim of this study was to determine the effects of during six weeks core and weight lifting trainings on strength development, muscle and tissue damage which may occur. Method: The research group consisted of sixteen volunteers who participated in the same age group. Participants were divided into two groups, core training group (n: 8) and weight lifting training group (n: 8). Participants continued to the program for the group to which the belonged lasted for three days a week for six weeks. Participant’s performance measures (Back and leg strength, hand grip strength, vertical jump) were taken and blood samples were taken twice at rest before and at the end of the training sessions. AST, ALT, LDH, CK and CK-MB levels were determined in the blood samples taken. SPSS 22 package program was used in the analysis of the obtained data. Paired samples t test was used for intra-group comparisons. Results: When intra-group analyses are made; there were significant differences in the leg strength, vertical jump, CK and CK-MB values of the weight lifting training group, it was determined that only differences in back and leg strength values occurred in the core training group(p<0,05). Conclusion: As a result, both core and weight lifting training have led to some improvement in strength parameters. It can be said that especially weight lifting training also causes muscle damage as well as strength development.
