Öğe Beslenme ve Diyetetik Öğrencilerinin Sosyal Medyada Diyetisyenlerin Paylaşımlarına Yönelik Görüşleri ve Sosyal Medyaya Bakış Açıları(Erciyes Üniversitesi, 21 Aralık 2023) Aktaç, Şule; Öztürk, Betül; Mete, Eda NurAmaç: Bu çalışmada Beslenme ve Diyetetik Bölümü öğrencilerinin diyetisyenlerin sosyal medya paylaşımları hakkındaki görüşleri ve sosyal medyaya bakış açılarının değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Ocak - Mayıs 2021 tarihleri arasında yürütülen çalışmaya çevrim içi olarak 53 üniversiteden 403 öğrenci katılmıştır. Birinci, ikinci, üçüncü ve dördüncü sınıf öğrencilerin sıklıkları sırasıyla; %22.1, %17.9, %22.6 ve %37.4 olarak saptanmıştır. Veri toplama aracı olarak; yedi soruluk genel bilgiler, 12 adet sosyal medya ile ilgili sorular, 40 soruluk diyetisyenlerin sosyal medya paylaşımları ve diyetetik öğrencilerinin görüşleri ve sekiz soruluk Sosyal Medya Kullanımı Ölçeği (SMKÖ) olmak üzere dört bölüm ve 59 sorudan oluşan anket kullanılmıştır. Bulgular: Katılımcıların genel SMKÖ toplam (X̅=2.18) puanı, orta seviyede sosyal medya kullandıklarını göstermiştir. Sosyal medyada diyetisyen hesaplarını takip etme oranı %91.6 olan öğrencilerin %88.5’i diyetisyenleri güncel gelişmeler, bilgi postu (%90.1) ve sağlıklı tarifler paylaştığı (%70.6) için takip etmiştir. Öğrenciler, diyetisyen paylaşımlarının kendilerinde daha zayıf olma baskısına (%43.2) ve kilo alma korkusuna (%49.9) neden olduğunu, beden algısını olumsuz etkileyebileceğini (%60.3) düşündüğünü belirtmiştir. Mezun olduğunda tanınırlığının artması için öğrenciyken sosyal medyada diyetisyen hesabı açılmasına katılmayan öğrencilerin büyük çoğunluğunu 4. sınıflar (%41.9) oluşturmuştur ve sınıf düzeyi arttıkça bu ifadeye katılmayan öğrencilerin sayısının da arttığı, bu ifade ile sınıf düzeyi arasında anlamlı farklılık gözlenmiştir (p<0.001). Öğrencilerin %80.9’u sosyal medyanın etik kullanılmamasının diyetisyenlik mesleğine zarar verdiği ifadesine katılmıştır. Sonuç: Öğrenciler beslenme ve diyetetik alanında güncel bilgiler ve sağlıklı tarifler paylaştığı için diyetisyenleri sosyal medyadan takip etmektedir. Diyetisyenlerin sosyal medyada yaptığı paylaşımlar öğrencileri daha sağlıklı seçimler yapmaları için yönlendirirken beden algısı yönünden olumsuz etkileyebilmektedir.Öğe Body Composition, Nutrition and Hydration Profile of Paralympic Athletes(Pamukkale University, 28 Ağustos 2024) Kahvecioğlu, Tuğba; Aktaç, ŞuleParalympic athletes are separated from healthy athletes by having various diseases/disabilities and using auxiliary equipment. This study was planned to compare paralympic athletes' hydration, body composition, and nutritional status. For this purpose, a comparison of branches, sex, and nutritional habits on training day and non-training day were examined by 66 professional athletes from the Turkish Physically Disabled Sports Federation included in the research. Demographic characteristics, anthropometric measurements, nutritional habits, and physical activity data of individuals were collected. Dietary, physical activity, and water balance scale records were determined to evaluate the nutritional, physical activity, and hydration status of these athletes, respectively. Food consumption data were analyzed with the Nutrition Information System (BeBis) in detail; energy, carbohydrate, protein, fat, water, vitamin D, vitamin B12, calcium, magnesium, and iron were examined. Measuring mid-upper arm circumference (MUAC) is a good indicator of skeletal muscle protein mass. While women’s MUAC was 28.9±3.8 cm and men’s MUAC was 30.7±7.0 cm, respectively. When the reference values recommended for healthy athletes are met, it has been observed that protein, carbohydrate, iron, and calcium didn’t meet the recommendations. Carbohydrate, dietary vitamin D, calcium and magnesium values were found to be higher on the training day than on the non-training day (p<0.05). There was no difference between spesific gravity, fluid intake during exercise or the amount of sweating of the athletes (p>0.05). The hydration status of the athletes was found to be inadequate in all conditions of gender, branch and the presence or absence of training.Öğe Body Composition, Nutrition and Hydration Profile of Paralympic Athletes(Pamukkale Üniversitesi Spor Bilimleri Fakültesi, 06.09.2024) Mungan, Tugba Kahvecioglu; Aktaç, ŞuleParalympic athletes are separated from healthy athletes by having various diseases/disabilities and using auxiliary equipment.

This study examined the effect of time-restricted feeding on impulsivity in adults. Methods: Thirty adults aged 25–41 years participated in this randomized controlled trial. The intervention group followed time-restricted feeding for 4 weeks and there was no energy restriction in the intervention group (n = 15) or control group (n = 15). Impulsivity was assessed before and after the intervention with the Barratt Impulsiveness Scale and the Go/NoGo task. Results: The compliance rate (the percentage of days when participants had a feeding time of ≤ 8 hours/day) of the intervention group to the time-restricted feeding pattern was 92.38 ± 4.24%. The Barratt Impulsiveness Scale-11 total score of the intervention group increased from 55.53 ± 6.37 to 59.47 ± 7.67 (p = 0.02). During the Go/NoGo task, an indicator of inhibitory control, the reaction time to food and non-food stimuli was significantly shortened in the intervention group (respectively; p = 0.009, p = 0.01). In the control group, no significant change was detected in impulsivity determined by the BIS-11 or Go/NoGo task. Discussion: This study showed that although time-restricted feeding may reduce body weight, it can lead to increased impulsivity and impaired inhibitory control.
