Effects of fast-velocity concentric resistance training in people with multiple sclerosis: A randomized controlled trial

Abstract

Objectives: To analyze the effects of a fast-velocity concentric resistance training (FVCRT) program on maximum strength of upper and lower limb, gait speed, walking endurance, fatigue, physical self-perception, and catastrophizing pain in people with multiple sclerosis (MS). Materials and Methods: Participants were randomized to either an experimental [EG] (n = 18) or a control [CG] (n = 12) group. The EG carried out 10-weeks of lower limb FVCRT. The CG did not perform any intervention. The maximum isometric voluntary contraction (MVIC) during knee extension, hand-grip strength, gait speed, walking endurance, fatigue, physical self-perception, and catastrophizing pain were measured. Results: Inter-group differences after intervention were found on the right and left sides in MVIC (p =.032; ES = -0.7 and p =.009; ES = -0.9), and hand grip strength (p =.003; ES = -1.0 and p =.029; ES = -0.7). After FVCRT, there was in increase in MVIC (p
