Günümüzde hipertrofi, vücut geliştirme sporu ile uğraşan amatörler/profesyoneller için planlanmış ilave kas kütlesi kazanımı ile ilişkilendirilmesine rağmen, sportif performansa olan katkılarından dolayı performans sporcuları ve genel sağlık düzeylerini korumak/geliştirmek isteyenler için de çok önemlidir. Literatür incelendiğinde, araştırmalar, bireylerin aynı çalışma yoğunluğuna sahip olmalarına rağmen farklı iskelet-kas hipertrofisine sahip olduklarını rapor etmektedir. Hipertrofik yanıta neden olan fizyolojik yol ve yolakların ne olduğu uzun yıllardır merak konusu olmuştur. Özellikle ülkemiz açısından, bu bağlamda herhangi bir araştırmanın yapılmamış olması dikkat çekicidir. Yaklaşık 2 milyona yakın fitness katılımcısının olduğu düşünüldüğünde, ayrıca hipertrofi konusu üzerine çalışma yürüten akademisyenler, antrenörler, öğrenciler ve sporcular için hipertrofinin olası hücresel mekanizmalarının bilinmesi ve anlaşılması son derece önemli katkılar sunacaktır. Dolayısıyla bu çalışmada, son yıllarda hipertrofik yanıtın muhtemel hücresel mekanizmaları olan; uydu hücre proliferasyonu, sitokin ve endokrin cevaplar hakkında kanıta dayalı cevaplar verilmeye çalışılmıştır. Bu çalışmada, akut ve kronik kuvvet antrenmanları sonrası görülen hipertrofik yanıtın rasyonel hücresel mekanizmalarının belirlenmeye çalışılması amaçlanmıştır.

Although hypertrophy is now associated with planned additional muscle mass gain for amateurs/professionals engaged in bodybuilding sports, it is also important for those who want to maintain/improve performance athletes and general health levels due to their contribution to sporting performance. When the literature is examined, researches reports that individuals have different skeletal muscle hypertrophy level, despite having the same intensity of work. It has been a matter of curiosity for many years what physiological pathways cause hypertrophic response. When it is thought that there are close to 2 million fitness participants, knowing and understanding of the possible cellular mechanisms of hypertrophy for academicians, coaches, students and athletes working on the topic of hypertrophy would be provide extremely important contributions. Therefore, this review has sought to provide evidence-based answers to the probable cellular mechanisms such as stellate cells proliferation, cytokines and endocrine responses of the hypertrophic response in recent years. The purpose of this review is to present literature-based evidence on the rationalize cellular mechanisms of the hypertrophic response.
