Spor bilimleri içinde önemli bir yere sahip olan antrenman ve egzersiz ile ilgili küresel çalışmaların sayısındaki artışa rağmen literatürde halen bibliyometrik çalışmalar bulunmamaktadır. Bu çalışma, antrenman ve egzersiz konusunda yayınlanmış bilimsel makaleleri bibliyometrik yöntemlerle incelemeyi amaçlamaktadır. 1980-2021 yılları arasında yayınlanan antrenman ve egzersiz makaleleri Web of Science'dan (WoS) indirilmiştir. Ülkelerin makale sayıları ile bazı gelişmişlik göstergeleri arasındaki korelasyon analizleri için Spearman korelasyon katsayısı kullanıldı. Üstel düzeltme, sonraki yıllarda yayınlanacak makalelerin sayısını tahmin etmek için kullanıldı. Atıf analizlerini ve trend konularını belirlemek için ağ görselleştirme haritaları kullanıldı. Toplam 37408 makale analiz edildi. Literatüre katkı sağlayan ilk 3 ülke ABD (n=13227), İngiltere (n=4481), Kanada (n=3211) oldu. En aktif dergiler Journal of Applied Physiology (n=4338), Medicine and Science in Sports and Exercise (n=3292), Journal of Strength and Conditioning Research (n=2743) oldu. En aktif ilk 3 kurum University of California System (n=696), University of Copenhagen (n=678) ve University of North Carolina (n=644) idi. Literatüre en aktif katkıyı yapan kişi William J. Kraemer'dir (Makale Sayısı=223). Antrenman ve egzersizle ilgili bu kapsamlı bibliyometrik çalışmada 37408 makalenin bir özetini paylaştık. Son dekatta (2013-2021) çalışılan konular direnç antrenmanı, futbol, atletik performans, yüksek yoğunluklu interval antrenman, spor, gençler, takım sporları, antrenman yükü, sakatlık önleme, sağlık, yaşam kalitesi, egzersiz terapisi, obezite, aerobik egzersiz, kas gücü, biyomekanik, denge, yürüyüş, kalp hızı değişkenliği ve hipertansiyon olarak belirlendi., Despite the increase in the number of global studies on training and exercise, which have an important place in sports sciences, there are still no bibliometric studies in the literature. This study aims to analyse the scientific articles that have been published on training and exercising by using bibliometric methods. Articles on training and exercise published between 1980 and 2021 were downloaded from the Web of Science (WoS). Spearman correlation coefficient was used for the correlation analysis between the number of articles and some development indicators of the countries. The exponential smoothing was used to estimate the number of articles to be published in the next years. Network visualization maps were used to identify citation analyses and trending topics. A total of 37408 articles were analysed. The top 3 contributing countries to the literature were USA (n=13227), UK (n=4481), Canada (n=3211). The most active journals were Journal of Applied Physiology (n=4338), Medicine and Science in Sports and Exercise (n=3292), Journal of Strength and Conditioning Research (n=2743). The top 3 most active institutions were University of California System (n=696), University of Copenhagen (n=678), University of North Carolina (n=644). The most active contributor to the literature was William J. Kraemer (Number of articles=223). We shared a summary of 37408 articles in this comprehensive bibliometric study on training and exercise. The topics studied in the last decade were determined as resistance training, football, athletic performance, high-intensity interval training, sports, youth, team sports, training load, injury prevention, health, quality of life, exercise therapy, obesity, aerobic exercise, muscle strength, biomechanics, balance, gait, heart rate variability, and hypertension.

The aim of this study is to investigate the publications related to FP, identify the top effective countries and journals, top productive researchers, and trend topics. Material and Methods: The data of this study were obtained using the Thomson Reuters WoS (Thomson Reuters, New York, NY, USA) database, separately for females and males. In the bibliometric analysis, ‘fertility preservation’ was used as a keyword. VOSviewer (Version 1.6.6) was utilized for bibliometric network visualizations. SPSS was used for the statistical analyses (Version 22.0)Results: Analysis results of the keywords used for men indicated 817 publications and for females indicated 2531 publications totally. The United States of America (USA) was the top country for the publications about both genders. The top three research fields for both genders were Obstetrics and Gynecology, Reproductive Biology, and Oncology. The journals that contributed to the literature most were Fertility and Sterility and Human Reproduction respectively in both gender categories. The correlation between the number of total fertility preservation articles and total cancers,Gross Domestic Product-World Bank (GDP-WB), Gross Domestic Product-International Monetary Fund (GDP-IMF), Human Development Index (HDI), and Internet Users (IU) was significant (r=0.482, p=0.017; r=0.609, p0.001; r=0.620, p0.001; r=0.365, p=0.043; r=0.479, p=0.006). Conclusion: It has been determined that researches on the protection of the fertility of cancer patients and infertile patients have increased from past to present. Also, it is observed that the economies of countries have an active role in research productivity.Keywords: Bibliometrics; fertility preservation; female; male.

Introduction: The cerebellum has been regarded as a valuable research topic over the years because of its numerous roles in motor and nonmotor functions. The aim of the current study was to provide a comprehensive and holistic evaluation of publications concerning the cerebellum over the last 40 years which can be a potential guide for future research related to the cerebellum. Material and Methods: The Web of Science database was used to identify the publications relating to the cerebellum between 1980 and 2019. The identified publications were analyzed using the bibliometric approaches. The number of the publications concerning the cerebellum to be published between 2020 and 2028 was predicted using the linear regression analysis. Results: The literature review revealed a total of 33,186 publications. The top three active countries were found to be the USA (7362), Japan (2987), and the UK (1994). A positive and significant correlation was found between the number of cerebellum articles produced by the countries and the development indexes of the countries (r = 0.743, P < 0.001; r = 0.676, P < 0.001, r = 0.656, P < 0.001). The top three productive journals were found to be the Journal of Neuroscience, Brain Research, and Cerebellum. The total number of cerebellum publications is expected to continue in an increasing trend and reach a total of 891 publications at the end of 2028. Discussion and Conclusion: Recent studies on the cerebellum have mostly focused on the cerebellar degeneration, functional connections of the cerebellum, and its relationship with various diseases such as ataxia, schizophrenia, Parkinson's disease, autism, and aneurysms.
