Besinsel Destek Kullanımı: Voleybol Örneği

Abstract

Bu çalışmada amaç, voleybolda en çok kullanıldığı bildirilen besinsel destekler (C ve D vitamini, demir, magnezyum, kafein, sporcu ve enerji içecekleri, dallı zincirli aminoasitler, HMB, glutamin, whey, kreatin, bikarbonat, karnitin) hakkında bilgi vermektedir. Derlemenin içeriği, daha önce çok sayıda araştırmanın toplanıp yorumlandığı besinsel desteklerle ilgili derleme ve ilgili yayınların referans listeleri ile voleybolcular üzerinde yapılmış araştırma makaleleri özetlenerek oluşturulmuştur. İçeriğin hazırlanmasında derlemelerden yararlanılmasının nedeni, çok sayıda ve farklı sonuçlara ulaşan araştırma makalelerinin seçiminde ortaya çıkabilecek bireysel yanlılığı ortadan kaldırmaktır. Voleybolcular üzerindeki çalışma sayısının azlığı nedeniyle voleybolda besinsel destek (takviye/suplement) kullanımına özgü bilgi yetersiz olsa da, suplementler ile ilgili verilen bilgilerin okuyana fikir verecek yeterlilikte olduğu düşünülmektedir. Sonuç olarak, suplementlerin yararlarını araştıran çalışmalar yapılmaya devam etmektedir ve kullanım yanıtları yöntemsel ve bireysel farklılık gösterebilmektedir. Diğer takviyelerin vücutta eksikliği olmadığı sürece sporcuda sağlık veya performansı iyileştirmesi olası değildir. Hatta antrenmana daptasyonunu köreltmesi nedeniyle performansa, yaralanma riskini artırması nedeniyle de sağlığa zararlı etkileri olabilir.

Use of Nutritional Supplements: Example of Volleyball

Abstract

The aim of this study is to provide information about nutritional supplements (vitamin C and D, iron, magnesium, caffeine, sports and energy drinks, branched chain amino acids, HMB, glutamine, whey, creatine, bicarbonate, carnitine) that are reported to be used most frequently in volleyball. The content of the review was created by summarizing the reviews about nutritional supplements, in which many studies have been collected and interpreted before, and reference articles of related publications and research articles on volleyball players. The reason for the use of reviews in the preparation of the content is to eliminate the individual bias that may arise in the selection of research articles with numerous and different results. Although the information specific to the use of nutritional supplements in volleyball is insufficient due to the low number of studies on volleyball players, it is thought that the information given about supplements is sufficient to give an idea to the readers. As a result, studies investigating the benefits of supplements continue to be conducted and responses differ methodologically and individually. It is unlikely that, the other supplements are unlikely to improve health or performance unless the athlete has a deficiency in their body. They may even have harmful effects on performance because they blind training adaptation and on health because they increase the risk of injury.
