Objective To evaluate the long-term preventive impact of strength training on muscle performance in older adults. Design A 7-year follow-up on a 1-year randomized controlled trial comparing the effects of combined resistance training and aerobic training and whole-body vibration training on muscle performance. Setting University training center. Participants Men and women (N=83; control [CON] group, n=27; strength-training intervention [INT] group, n=56) between 60 and 80 years of age. Interventions The INT group exercised 3 times weekly during 1 year, performing a combined resistance training and aerobic training program or a whole-body vibration training program. The former training program was designed according to American College of Sports Medicine guidelines. The whole-body vibration training program included unloaded static and dynamic leg exercises on a vibration platform. The CON group did not participate in any training program. Main Outcome Measures Static strength (STAT), dynamic strength at 60°/s (DYN60) and at 240°/s (DYN240), speed of movement at 20% (S20). Results From baseline to postintervention, muscle performance did not change in the CON group, except for S20 (+6.55%+2.88%, P<.001 one year of strength training increased stat dyn60 dyn240 and s20 in the int group. between baseline follow-up muscle performance decreased both groups. however showed a significantly lower loss group respectively compared with con this positive impact might be due to preservation training-induced gains given similar annual decline rates groups from postintervention follow-up. additionally trained participants aging seems velocity-dependent power more basic as total losses did not differ> Conclusions A 1-year strength-training intervention results in an improved muscle performance in older adults 7 years after their enrollment in the intervention. However, an extensive exercise program cannot attenuate the age-related decline once the intervention stops. |
