Introduction: Good functional performance in elderly people greatly
improves their c changes of independence and well-being. Conversely,
bad functional performance can impair their capability of managing the
activities of daily life.. The main goal of this study was to investigate the
effects of a 6-months’ multimodal training intervention on the physical
performance of males and females, possible gender differences and the
outcome 6 and 12 months after its completion..
Material and methods: This study examined 71-90 year old healthy
seniors (n=117) participating intheAGESReykjavikStudy.lt was
a randomized and controlled cross-over trial, conducted in three
6-months’ phases (time-points). After enrollment and baseline assess-
ments, the study group was divided in two. Group 1 received 6-months’
training while group 2 served as a control. In the second 6 months'
phase, group 1 received no formal training while group 2 did. In the third
phase, neither group received training. The groups' physical conditions
were assessed after each phase.
Results: After 6-months’ training, 32% improvement was seen in physi-
cal activity among males (p<0.001) and 39% among females (: <0.001).
In physical performance, 5% improvement was seen for males (p<0.01)
and 7% forfemales (p<0.001). Strength increased by 8% for males
(o<0.001) and 13% forfemales (p<0.001). For both sexes, about 10%
increase was seen in dynamic balance in the 8-foot up-and-go test
( <0.001) and 5-6% in walking distance for both sexes in the six minutes
walking test (r<0.001). For both sexes, body mass index decreased by
about 2% (p<0.001). No difference was seen between the sexes.in the
training results. Both sexes retained long-term effects of the training on
physical performance and dynamic balance for at least 12 months.
Conclusions: Multimodal training intervention has positive effects on
physical performance in older individuals, the sexes respond similarly
to the training and retain achieved improvement for at least 12 months.
The research indicates that moderate and systemic training for this age
group could be a part of conventional health service for this age group.
Keywords: Aging, training, functionalperformance, muscle strength, six-minute walking test
