Human skeletal muscle mass constitutes the major body proportion and essential for their functional independence. Aging is the strange phenomenon which is the main rationale for decreasing the skeletal muscle mass by causing a variety of morphological changes in the form of declining of myofiber cross sectional area and satellite cells content during the years. Satellite cells are known as the stem cells of skeletal muscles which play a very important role in skeletal muscle growth. They give rise new myonuclei in response of any stimulus, which provides genetic material for the purpose of protein synthesis. Though in aging process, number of myonuclei is not decreased but still they need any threshold or stimulus that is required for their functionality. Currently, strength training is considered as one of the best available valid and reliable methods for countering aging process. Strength training provides the certain threshold which is necessary for satellite cell activation and proliferation and for the restoration of functional capability of myonuclei. Strength training has the ability to restore morphological changes occur during the aging process. It is equally effective in elderly is as well as in young adults. In this review, we will elaborate how strength training is effective for restoration of the morphological changes occur during aging process.
