Cessation of Exercise in the Institutionalized Elderly: Effects on Physical Function

Purpose: The objectives of this study were (1) to examine the effects of a 12-week exercise cessation period separating two 12-week exercise sessions on physical variables in an elderly institutionalized population and (2) to explore overall programme effectiveness. Methods: The functional mobility of 25 elderly institutionalized adults participating in an existing exercise programme was examined using a one-group, interrupted time-series design. Functional mobility was evaluated at four time points during two cycles of a 12-week exercise programme, alternating with a 12-week period of no formal exercise. Results: The primary outcome was the change in functional mobility scores, assessed at baseline, 12, 24 and 36 weeks. In both the higher-functioning (HF) group and the lower-functioning (LF) group, the cessation of exercise was associated with deterioration in physical function. The overall non-continuous nature of the programming under study also seemed to be detrimental to the physical function of the LF group. Conclusions: Findings of this small-sample study support the need to modify common practices in exercise programming for older, institutionalized people.
