Résumé
Resistance training and protein supplementation are recommended strategies to combat sarcopenia. Quantification of muscle thickness (MT) by musculoskeletal ultrasound is a promising method to follow changes in skeletal muscles. The aim of this study was to investigate the effect of six months of resistance training with or without nutritional supplementation on MT of M. quadriceps in institutionalized old adults. This is a prospective, randomized, multi-arm parallel and controlled intervention study. This study was conducted in five different retirement care facilities. Institutionalized individuals (mean age 82.6±6.2 years) were randomly assigned to an elastic band resistance training (N.=41), training with nutritional supplementation (N.=36) or control group (N.=40). Health status and handgrip strength were investigated at baseline. MT of all parts of M. quadriceps of the left leg was assessed using musculoskeletal ultrasound at baseline and after six months. Linear regression models adjusted for age, BMI and sex were calculated to investigate the influence of baseline characteristics on MT. Multivariable regression analyses were performed for investigation of study intervention on MT. Follow-up examinations were performed after 12 and 18 months. Handgrip strength of both hands was significantly correlated with MT of M. vastus lateralis. Moreover, the sum of regularly taken medication was significantly correlated to MT of all parts of quadriceps. Six months of training or nutritional supplementation was not able to alter MT. However, participants with lower baseline MT values or a higher number of diseases and medications at baseline showed significant higher increases in MT after intervention. Resistance training using elastic bands with or without nutritional supplementation did not alter MT of M. quadriceps of old institutionalized individuals. However, baseline values and health status had a significant influence on the training effect. As old individuals are very heterogenic according to their health and muscle status; further studies might focus on individualizing training regimes with particular emphasize on accompanied diseases and medications of this population.

AIM
OBJECTIVE
Quantification of muscle thickness (MT) by musculoskeletal ultrasound is a promising method to follow changes in skeletal muscles. The aim of this study was to investigate the effect of six months of resistance training with or without nutritional supplementation on MT of M. quadriceps in institutionalized old adults.
DESIGN
METHODS
This is a prospective, randomized, multi-arm parallel and controlled intervention study.
SETTING
METHODS
This study was conducted in five different retirement care facilities.
POPULATION
METHODS
Institutionalized individuals (mean age 82.6±6.2 years) were randomly assigned to an elastic band resistance training (N.=41), training with nutritional supplementation (N.=36) or control group (N.=40).
METHODS
METHODS
Health status and handgrip strength were investigated at baseline. MT of all parts of M. quadriceps of the left leg was assessed using musculoskeletal ultrasound at baseline and after six months. Linear regression models adjusted for age, BMI and sex were calculated to investigate the influence of baseline characteristics on MT. Multivariable regression analyses were performed for investigation of study intervention on MT. Follow-up examinations were performed after 12 and 18 months.
RESULTS
RESULTS
Handgrip strength of both hands was significantly correlated with MT of M. vastus lateralis. Moreover, the sum of regularly taken medication was significantly correlated to MT of all parts of quadriceps. Six months of training or nutritional supplementation was not able to alter MT. However, participants with lower baseline MT values or a higher number of diseases and medications at baseline showed significant higher increases in MT after intervention.
CONCLUSIONS
CONCLUSIONS
Resistance training using elastic bands with or without nutritional supplementation did not alter MT of M. quadriceps of old institutionalized individuals. However, baseline values and health status had a significant influence on the training effect.
CLINICAL REHABILITATION IMPACT
CONCLUSIONS
As old individuals are very heterogenic according to their health and muscle status; further studies might focus on individualizing training regimes with particular emphasize on accompanied diseases and medications of this population.
