Women who exercise throughout life may keep their muscle power as they age, a new study suggests.
For the study, researchers from Ball State University in Muncie, Ind., examined muscle strength, power and the size and type of muscle fibers in the thighs of three groups of women.
Seven women in one group were over 70 and had exercised regularly for nearly 50 years. The second group had 10 women who averaged 25 years of age and also worked out regularly. The third group comprised 10 women over 70 who did not exercise regularly.
