Fundamental building blocks of our bodies are called as cells. Cellular changes play a major role in the ageing process. Cellular senescence is a process where there is inability of the cells to proliferate due to loss of replicative or growth potential. Physical inactivity is the absence of any movement produced by muscles of body, which requires energy. Various molecular mechanisms are responsible for cellular senescence. One important factor is telomere, which protects chromosome and is chiefly responsible for the replicative process. Physical activity is found to be associated with reduced disease risk and increased longevity through various cellular and molecular mechanisms. However, evidences relating to cellular senescence and physical inactivity are found in sparse. This review aims to discuss the importance of physical activity and role of telomere in senescence and other aging processes.
