Effects of progressive strength training on the performance of the Functional Reach Test and the Timed Get-Up-and-Go Test in an elderly population from the rural north of Portugal.

The purpose of this study was to examine the effect of an intensity progressive strength training program on the performance of two tests related to fall risk: the Functional Reach Test (FRT) and the Timed Get-Up-and-Go Test (TUG). Twenty subjects were randomly included in one experimental group (age 73 +/- 6 years old) and one control group (age 75 +/- 5 years old). Subjects from the experimental group participated in a strength-training program consisting of three sessions each week for a period of 14 consecutive weeks, from 50% to 80% of 1RM. A 2 (group: experimental vs. control) x 2 (pre-post: pre-test vs. post-test) repeated measures ANOVA was carried out on subjects in TUG and FRT performance. Mean FRT results from the pre-test were significantly lower than mean results from post-test. The two main effects were qualified by a significant group x pre-post interaction, F(1,18) = 39.23, P < 0.001, identifying markedly different performance profiles. Mean TUG results from the pre-test were significantly lower than mean results from post-test. The two main effects were qualified by a significant group x pre-post interaction, F(1,18) = 50.74, P < 0.001, again identifying markedly different performance profiles. Globally, the obtained results through our progressive strength-training program showed important improvements in functional task performance and in preventing falls.
