The Effects of Manual Resistance Training on Improving Muscle Strength of the Lower Extremities of the Community Dwelling Elderly -A Clinical Intervention Study with A Control Group-

Abstract

Abstract. [Purpose] This study focused on the effects of Manual Resistance Training (MRT) performed by elderly people for their lower extremities. [Subjects and Methods] The subjects were 53 elderly persons. The isometric strength of the right knee-extensor of the subjects in the intervention group was assessed after MRT once a week for 12 weeks followed by MRT, twice a week for 12 more weeks. Subjects in the control group only received the muscle strength measurement and did not perform MRT.[Results] From the baseline, the muscle strength of the intervention group significantly increased by 13.2% after 12 weeks, and 29% after 24 weeks. A significant difference was observed between the muscle strength of the intervention group and that of the control group. Those with greater muscle strength experienced relatively low muscle strength augmentation, compared with those with less muscle strength.[Conclusion]MRT resulted in improvements in muscle strength, similar to the results reported for a prior intervention with a resistance training method. The intensity of the MRT was inferred to be more than 70% of 1-repetition maximum. MRT may have less impact if it is performed by people with relatively high muscle strength.

“…Finally, because the experimental group only consisted of males and females in their 20s, the results cannot be generalized to all ages. The present results along with those of studies assessing resistance exercise for the elderly 26 ) , aerobic exercise 27 ) , aquatic exercise 28 ) , treadmill walking 29 ) , and muscular exhaustion recovery 30 ) are expanding the knowledge of the relationships of muscle groups with RPE.…”

A influência do controle subjetivo de intensidade sobre fadiga percebida e lactato capilar em duas formas de treinamento resistido

“…However, considering that only a small portion of the world population attend gyms 5 , recent studies have suggested alternative forms that do not depend on equipment in order to permit the application of RT in nonspecific environments and places such as residential condominiums, hospitals, clinics, basic health units, universities, schools, and companies, among others [6][7][8][9] . One alternative of RT that is being investigated is manual resistance training (MRT) [7][8][9][10] , a concept that uses manual resistance imposed by a second person in the direction opposite to the movement performed by the exercising subject ( Figure 1A, 1B). Previous studies have shown that MRT is effective in increasing strength levels in different populations [7][8][9][10] .…”

Furthermore, the effects of MRT are similar to those of free weight resistance training (FWRT) as long as the volume and intensity are comparable 7,11 .…”

“…Furthermore, the effects of MRT are similar to those of free weight resistance training (FWRT) as long as the volume and intensity are comparable 7,11 . However, since, in contrast to FWRT, this type of training does not use equipment, the objective control of intensity is not possible and the use of subjective methods, such as rating of perceived exertion (RPE), is therefore recommended for the control of internal load 9,11 . To our knowledge, there are no studies comparing the effects of the use of RPE as a method to control intensity on objective and subjective markers of exercise intensity between MRT and FWRT.…”

“…Em âmbito clínico e em populações especiais, estudos mostraram que o TRM foi superior ao controle em promover melhora sobre a força e capacidade funcional de adolescentes [11] e idosos institucionalizados [12].…”
