이 연구는 웰니스적인 삶을 영위하기 위한 텔로미어의 연구 동향을 알아보고자 한 연구로써 텔로미어는 세포 복제 능력을 조절하고 게놈 안정성을 유지하는 데 중요한 역할을 하며, 세포가 분화될수록 이 부분이 점점 짧아지므로 이를 측정하여 현재의 건강과 노화 상태를 알려주고 장래 질병의 발생 위험성을 예측할 수 있는 검사방법 중의 하나로 제시되고 있다. 따라서 이 연구에서는 국내, 외 텔로미어와 관련된 연구를 토대로 텔로미어에 영향을 주는 요인, 신체활동, 운동 및 이용 가능한 문헌을 중심으로 자료를 검토하였다. 텔로미어의 점진적인 단축은 개인의 건강과 수명에 영향을 미치는 체세포의 노화, 세포사멸, 또는 유발적 변화로 이어진다. 텔로미어 점진적 단축은 산화스트레스와 염증반응을 야기하는 조건과 라이프스타일, 비만, 흡연 등은 질환을 유발시키며 텔로미어 길이 변화에 영향을 줄 수 있다. 또한 신체활동과 규칙적인 운동은 텔로미어 단축의 비율을 감소하거나 방지할 수 있는 큰 잠재력을 가지므로 신체활동과 운동을 통하여 심폐체력 및 운동수행능력과 관련된 체력을 증가시키는 것은 세포노화를 방지하는 데 도움이 될 것으로 사료 된다. The study is aimed at identifying trends in telomere’s research to lead a wellness life, which plays an important role in controlling cell cloning capabilities and maintaining genome stability, and as cells differentiate, this part becomes shorter and shorter, indicating current health and aging conditions. Therefore, based on studies related to domestic and foreign languages, the study focused on factors affecting telomeres, physical activity, exercise, and available literature. Progressive shortening of telomeres leads to aging, apoptosis, or induced changes in somatic cells that affect the health and lifespan of individuals. The gradual reduction of telomeres can cause conditions that cause oxidative stress and inflammatory reactions, lifestyle, obesity, smoking, etc. to cause diseases and affect changes in telomere length. In addition, physical activity and regular exercise have great potential to reduce or prevent the rate of telomere shortening, so increasing cardiopulmonary and motor performance-related physical strength through physical activity and exercise is considered to help prevent cell aging.
