Bu araştırmada, lisanslı sporcuların akıllı telefon, internet bağımlılığı ve gelişmeleri kaçırma korkuları arasındaki ilişkinin incelenmesi amaçlanmıştır. Çalışma nicel araştırma yöntemlerinden betimsel ve ilişkisel tarama modelinde tasarlanmıştır. Çalışmaya, üniversitelerin spor eğitim kurumlarında öğrenim gören toplam 548 gönüllü lisanslı sporcu dahil edilmiştir. Veri toplama aracı olarak Nomofobi, İnternet bağımlılık ve Gelişmeleri Kaçırma Korkusu Ölçeği kullanılmıştır. Verilerin analizinde Independent T testi, One-Way Anova ve Çoklu doğrusal regresyon testi kullanılmıştır. Korelasyon analiz sonuçlarında ise gelişmeleri kaçırma korkusu, nomofobi ve internet bağımlılığı alt boyutları arasında orta düzeyde pozitif yönde ilişki tespit edilmiştir. Ayrıca gelişmeleri kaçırma korkusu ve nomofobinin internet bağımlığının önemli bir yordayıcısı olduğu söylenebilir. Sonuç olarak, yaşadığımız dijital çağ, dijital bağımlılık ve benzeri bağımlılıkların ortaya çıkmasında önemli bir etkiye sahiptir. Bu bağımlılıklardan çözüm noktasında dijital detoks oldukça önemlidir. Dijital medya aracılığıyla yayılan metinleri, mesajları görselleri doğru okumak ve anlamlandırmak da son derece mühimdir.

This study aims at identifying the emotional, physical, psychological and social states of individuals who had to stay home for a while due to the measures taken to prevent the spread of the Covid-19 pandemic, and to determine what kind of recreational activities they preferred during this period. We used mixed research method and composed the study group of 479 consisting 297 female and 182 male participants with non-random, convenience sampling method. Data was collected through questionnaires of open-ended qualitative questions. Findings addresses that recreational activities during long home stay in a pandemic have psychological, socio-cultural and physical benefits. Social isolation during such circumstances is known to be limiting the physical mobility of individuals and it did so in this Covid-19 pandemic process. While the main activity source was of technology of the people attended this research, we also observed that they are aware of the variety and the benefits of recreational activities at the same time. The respondents stated that the coronavirus outbreak had negative effects in terms of economical, social, psychological and physiological contexts, but with the outbreak; staying in social isolation had also positive effects on their family such as exploring new things together, happiness and spending time effectively. One other remarkable aspect is that respondents reported that they would do recreational activities soon after the social isolation period ends. In the results of the research, it is suggested that it is necessary to resort to recreational activities in order to both reduce the spreading effect of the virus in isolation at home and to overcome this process with the least negative impact, and individual and institutional efforts should be made for this.

This study aims to investigate the effects of different levels of royal jelly supplementation on biochemical parameters in swimmers. Randomly selected 40 male swimmers aged 18 to 25 years attending the same trainings were recruited. Swimmers were assigned to 4 groups each with 10 subjects. Varying amounts of royal jelly (2, 1 g and 500 mg) were given to the 1st, 2nd and 3rd groups and placebo (corn starch) to the 4th group. Participants were trained by swimming totally 20 km in 2 h on 5 days a week for 4 weeks. Resting blood samples were taken before royal jelly administration and after 30 days of application. Then biochemical analyses were performed. Different levels of royal jelly were found to be ineffective on glucose, total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, lactate dehydrogenase (LDH), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT) levels of the swimmers. Blood urea nitrogen (BUN) and creatinine levels increased after the training program, and BUN level was higher in the group receiving 500 mg royal jelly than those in the other groups. The increment in creatinine levels was higher in those groups receiving higher amounts of royal jelly after the training. A supplementation of 500 mg, 1 and 2 g/day of royal jelly throughout the 30 day-exercise program was not significantly effective in the swimmers. Also, due to its high amino acid content, BUN and creatinine levels tended to increase. Key words: Royal jelly, swimming, exercise, biochemical parameters, ergogenic aids.

Bu çalışmada, spor ve teknoloji kavramları ile birlikte Olimpik spor branşlarında kullanılan teknolojik sistemlere ve bunların kullanım alanlarına değinilmiş olup farklı uygulamaların ve sistemlerin spor branşlarındaki kullanım şekillerinden kısaca bahsedilmiştir. Teknoloji ile birlikte günümüzde sıklıkla kullanılan ve birçok spor branşına uyarlanmış olan teknolojik sistemler ile bu sistemlerin olimpik branşlar arasındaki ilişkisi incelenirken, branşlara özgü örnekler de verilmiştir. Ayrıca spor branşlarında kullanılan bu teknolojik sistemlerin branşlara ve üst düzey sporculara etkisine, kullanım amaçlarına, kullanım yerlerine, spor branşlarındaki kullanım sıklığına ve teknolojinin modern olimpiyat oyunları üzerindeki etkisine değinilmiştir. Araştırmada sporun, teknolojik sistemlerin entegre edilmesiyle birlikte geldiği boyutla ilgili alan yazın çalışmalarına da yer verilmiştir. Araştırma, sporda teknoloji kullanımına yönelik bir derleme çalışmasıdır.

Purpose: The impact of technological transformations in all sectors is undeniably significant, especially in fitness family business. The aim is to examine the digital transformation perceptions of fitness centre employees and the effects of perceived empowerment on their job performance in family business in Turkey.Design/methodology/approach: The sample was 334 fitness centre employees. Four variables were evaluated (digital transformation, meaning competence, self-determination and job performance), and PLS-SEM was used.Findings: The digital transformation process in the fitness sector can be considered as an important factor in terms of creating new business ventures. Our results showed that digital transformation perceived by family business employees had a significantly influence on the meaning competence of the employees. Also, the meaning competence of employees was a mediator between the digital transformation and job performance.Practical implications: Managers of family businesses must take into account that an appropriate digital transformation of their products and/or services has an impact on the meaning competence of their employees. Thus, through increased competence in employee performance, the digitization of family business fitness will lead to higher employee performance and productivity.Originality/value: This study innovates by linking digital transformation as a factor influencing the coach's own motivation and self-perceived competence in the use of technology to their job performance.
