97 older men were randomized to one of three groups to assess the impact of high- versus low-intensity training over a 1 year period and its residual effects. Patients were allocated to either a combined resistance and aerobic training (R+A) group, a whole-body vibration (WBV) training group, or a control group. Following evaluations over 2 years, results indicated that for the first year the combined resistance and aerobic training and whole-body vibration training programs equally improved patients' muscle volume, strength, quality, and power in the lower limbs. However, following the completion of the program most of these benefits on muscle volume were lost, whereas their residual impact on strength, quality and power differs somewhat, probably as a result of the specificities of each training principle.
