    (Univ Ljubljana, Fac Sport, 2019) Sahin, Gulsah; Koc, Hurmuz; Baydemir, Baris; Abanoz, Hasan; Coskun, Ali; Gunar, Bilgetekin Burak
    The aim of this research was to examine the differences in agility, flexibility, aerobic capacity, vertical jump and vertical anaerobic power according to age and sex in children and young fencers. 76 children and young fencing athletes from 9-17 years (girl:30 and boy:46) who camped in Dardanos campus of Canakkale Onsekiz Mart University participated in the research. The measurements and tests were conducted by the Sports Science and Athlete Health Research and Application Center. Length and weight measurements, BMI calculation, T-test for agility, Yo-Yo IR1 test and shuttle running test for aerobic capacity, maxVO(2) calculation equations, vertical jump test, anaerobic vertical power calculation, sit and reach test for flexibility were used in the study. ANOVA to determine the difference between age groups, t test for gender comparison was used. The level of significance was accepted as p < 0,05. As a result of the research, maxVO(2), elasticity, vertical jump and anaerobic vertical power parameters were found significant different between age groups (p<0,05). Accordingly, it was found that the flexibility of girls was significantly higher than boys (p<0,05). However, there was no found significant difference between girls and boys in VO(2)max, vertical jump, anaerobic vertical power and T test parameters (p>0,05). Vertical jump distance, vertical power, maxVO(2), and agility are similar in boys and girls. Flexibility in girls is better than boys. Differences in performance can be seen among age groups.

    Benefits of A2 Milk for Sports Nutrition, Health and Performance
    (Frontiers Media Sa, 2022) Kaplan, Merve; Baydemir, Baris; Gunar, Bilgetekin Burak; Arslan, Aysenur; Duman, Hatice; Karav, Sercan
    Bovine milk is one of the best pre-and pro-workout sources for athletes owing to its rich nutritional content. Even though bovine milk consumption significantly benefits athletes' health and performance, many athletes cannot consume bovine milk since they struggle with gastrointestinal problems caused after milk consumption. Especially, the consumption of regular milk, which contains A1 beta -casein, is associated with a variety of diseases ranging from gastrointestinal discomfort to ischemic heart diseases. The main reason behind this is related to beta -casomorphine 7 (BCM-7), which is derived from A1 beta -casein during the digestion of A1 milk. A1 beta -casein is formed as a result of a point mutation in the position of 67(th) in the amino acid sequence A2 beta -casein by changing proline to histidine. Therefore, this mutated form of beta -casein in regular milk cannot easily be digested by the human-associated digestion enzymes. A2 milk, which includes A2 beta -casein instead of A1 beta -casein, is the best substitute for regular milk with the same nutritional content. This natural form of milk positively affects the athlete's health as well as performance without causing any gastrointestinal discomfort or more serious problems which are seen in the consumption of regular milk. In this review, A2 milk and its potential health effects in comparison to diseases related to A1 milk consumption are discussed.
