The study showed the effects of a 10-week resistance training program on flexibility of elderly women (n = 11) between 62 and 78 years of age. The control group was composed of 8 women (62 to 73 years old) who were physically inactive. Flexibility was evaluated through the sit-and-reach test, performed both before and after the training program. After an initial evaluation, individuals started a training program, which consisted of 8 exercises for the entire body, without the performance of any flexibility exercise. The training program resulted in significant increase (p < 0.001) of flexibility in elderly women (approximately equal 13%). No significant differences were found in the control group. We conclude that weight training without performance stretching exercises does increase flexibility in elderly women.
