Effects of flexibility training on enhancing spinal mobility in older women

The purpose of this study was to examine the extent to which spinal flexion and extension, or spinal mobility, could be improved in a population of older adults participating in a 10 week flexibility training program. Twenty female volunteers, mean age 71.8, were randomly assigned to either the experimental group (flexibility training) or the control group (no training). Prior to the initiation of training, all subjects were tested for total spinal mobility, the combined sum of spinal flexion and extension. Subjects in the experimental group were exposed to a series of flexibility exercises, three times per week, for 20-30 minutes in duration, for a total of 10 weeks. The control group participated in an alternative exercise program with the experimental group, including walking, swimming, dance, and other locomotor activities, however, they did not receive the additional flexibility training. At the conclusion of the 10 week period, all subjects were retested for spinal mobility, using back flexion and extension measures. Results indicated a significant improvement in spinal mobility in the experimental group, and virtually no measurable change in the control group. This study suggests that specialized training in back flexibility for older adults is warranted, and that significant gains in spinal mobility can be obtained, regardless of age.
