    (Instituto Politécnico de Setúbal, 2025) Arslan, Utku; Sanchez-Oliver, Antonio Jesus; Günalan, Elif
    Dietary supplements (DS) are of great interest among bodybuilders today due to their performance-enhancing and muscle development-supporting effects. However, unconscious use of these products can lead to adverse health consequences. Especially among amateur athletes, risk factors increase due to a lack of information, misdirection, and information from unreliable sources. This research aimed to examine the habits of sports supplement usage, frequency of use, preferred types of supplements, and motivation sources for these habits among amateur athletes in Türkiye.

    (Instituto Politécnico de Setúbal, 2025) Mor, Ömer; Bayraktar, Bülent; Sanchez-Oliver, Antonio Jesus; Günalan, Elif
    Handball is popular with high physical, physiological, and psychological demands. In addition to high-intensity movements, handball players must have performance components such as strength, agility, and speed and a suitable aerobic form to cope with high-intensity efforts. An optimal nutrition strategy helps maintain physical and cognitive performance, supports injury prevention, return to play, training adaptations, accelerates, and optimizes recovery processes. It has been stated in the literature that handball players tend to use nutritional supplements (NS) to facilitate the achievement of their nutritional goals. Therefore, studying how handball athletes use NS can offer an important understanding of the factors influencing their success. This study investigates supplement use among Turkish handball players and assessing the factors that shape their supplementation practices.

    (MDPI Publishing, 2025) Mor, Ömer; Sanchez-Oliver, Antonio Jesus; Bayraktar, Bülent; Günalan, Elif
    Handball is a sport that demands explosive movements and unique skills, and its popu larity has been rising in recent years. This study evaluated elite handball players’ nutri tional supplement (NS) use profiles and the differences in sex, competition level, and com petition type based on the Australian Institute of Sport (AIS) criteria. The data collection form contains questions about participants’ sociodemographic characteristics, training de tails, use of supplements, and related factors. Supplements were classified into A, B, C, and D classes according to the scientific evidence level of the AIS. The study involved 92 elite handball athletes, comprising 48 professionals and 44 amateurs, and included 37 fe males and 55 males. The most frequently used supplements among participants were magnesium (37.0%) (Group C—AIS), vitamin C (20.7%) (Group B—AIS), whey protein (19.6%), sports bars (19.6%), and vitamin D (19.6%) (Group A—AIS). Regarding sex dif ferences, a significant difference was observed only in Group C supplements, with male players using them more frequently than female players (p < 0.05). Professional athletes exhibited a significantly higher prevalence of supplement use, covering total, Group A, sports foods, performance supplements, and Groups B and C, relative to amateur players (p < 0.05). The results reveal that handball players have limited awareness of NS, empha sizing the need for training and consulting services.

    Safe or dangerous? Evaluating group a sports supplements in the context of the epithelial barrier hypothesis
    (Instituto Politécnico de Setúbal, 2025) Sadık, Merve; Aladağ, Esra; Bayraktar, Bülent; Sanchez-Oliver, Antonio Jesus; Günalan, Elif
    The epithelial barrier hypothesis suggests that the integrity of epithelial barriers in the skin, respiratory tract, and intestinal mucosa contributes to various chronic diseases. Long-term and high-intensity training, dehydration, malnutrition, etc., can cause epithelial barrier sensitivity in elite athletes. Elite athletes commonly consume sports supplements (SS) to enhance performance, support physical appearance, and prevent nutrient deficiencies. Scientific evidence indicates that SS can also affect the integrity of epithelial barriers. This study aims to discuss the potential effects of SS classified as Group A by the Australian Sports Institute (AIS) on epithelial barrier integrity.
