Abstract
Objective
To compare the effects of classic progressive resistance training (PRT) versus eccentric
strength-enhanced training (EST) on the performance of functional tests and different
strength manifestations in the lower limb of people with multiple sclerosis (PwMS).
Design
Experimental trial.
Setting
Strength training program.
Participants
PwMS (N=52; 19 men, 33 women) belonging to MS associations from the Castilla y León,
Spain.
Interventions
Participants were assigned to 1 of 2 groups: a control group that performed PRT or
an experimental group that performed EST. In both groups, the knee extensor muscles
were trained for 12 weeks.
Main Outcome Measures
Before and after 12 weeks of training, maximal voluntary isometric contraction and
1 repetition maximum (1RM) of the knee extensors were evaluated, as were the Chair
Stand Test (CST) and Timed 8-Foot Up and Go (TUG) functional tests.
Results
No differences were found between the groups in the initial values for different tests.
Intragroup comparisons found significant differences in CST (F=69.4; P<.001), TUG (F=40.0; P<.001), and 1RM (F=57.8; P<.001). For intergroup comparisons, EST presented better results than PRT in the CST
(EST, 4.7%±2.8%; PRT, 1.9%±2.8%; F=13.1; P=.001) and TUG (EST, −2.9±4.7; PRT, −.41±5.6; F=5.6; P=.022).
Conclusions
In PwMS, EST leads to improvements in 1RM, TUG, and CST that are similar to those
of PRT. However, for patients who participated in this study, the EST seems to promote
a better transfer of strength adaptations to the functional tests, which are closer
to daily-living activities.
