- Brief Summary
This study evaluates two strength training protocols (one in peripheral muscles and one in inspiratory muscles) in the improvement of skeletal muscle mass and function in institutionalized elderly with sarcopenia. Participants will be assigned randomly in a control or one of both experimental groups.
- Detailed Description
Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength with a risk of adverse outcomes such as physical disability, poor quality of life and death (Goodpaster et al, 2006; Delmonico et al, 2007). The contributing factors are those related to aging process, non-optimal diet, bed rest or sedentary lifestyle, chronic diseases and certain drug treatments. Most of these factors are present in the older population with comorbidity, frequently institutionalized to receive a professional long-term care.
Since the European Working Group on Sarcopenia in Older People (Cruz-Jentoft et al, 2010) recommends using the presence of both low muscle mass and low muscle function (strength and/or physical performance) for the diagnosis of sarcopenia, interventions should be focused in both criteria. The aim of this study is to prevent loss of skeletal muscle mass and strength in institutionalized elderly with sarcopenia.
To this purpose, the investigators study undertakes two physiotherapy interventions to preventing/treating Sarcopenia, namely, maintenance of muscle mass and improvement of strength in peripheral and respiratory muscles. Both interventions are common in the following features: supervision, duration, frequency and intensity of the training program.
The primary outcomes are those related to muscle mass and strength. Secondary outcomes will be related to muscle function (muscle endurance and/or physical performance), costs and health status (number of falls and fractures, exacerbations of chronic diseases, hospitalizations and deaths during the year after concluding the physiotherapy interventions).

Group Intervention Description Respiratory training group Inspiratory Muscle Training (IMT). Participants will breathe against a load ≥ 50% of their baseline MIP, after which loads will increase according to the participant's tolerance across the remaining training period, using a Borg scale rating of 4 to 6 on perceived exertion as an indicator of adequate training intensity. Intervention: Inspiratory Muscle training (12-weeks) Peripheral training group Peripheral muscle training Participants will load ≥ 50% of their maximum muscle force (Kg), after which load will increase according to the participant's tolerance across the remaining training period, using a Borg scale rating of 4 to 6 on perceived exertion as an indicator of adequate training intensity. Intervention: Peripheral muscle training (12-weeks)
- Primary Outcome Measures
Name Time Method Change in Muscle mass The groups will be assessed at baseline (pre-intervention) and at the end of the training program (week 12, post-intervention). Bioimpedance analysis (BIA) estimates the volume of fat and lean body mass. The test itself is inexpensive, easy to use, readily reproducible and appropriate for both ambulatory and bedridden patients. Reference: J Aging Phys Act 2015;23(4):597-606. Korean J Intern Med 2016;31:643-650.
Change in Maximum Respiratory Pressures (MIP and MEP) The groups will be assessed at baseline (pre-intervention) and at the end of the training program (week 12, post-intervention). MIP and MEP are probably the most frequently reported non-invasive estimates of respiratory muscle strength. Ever since Black and Hyatt (1969) reported this technique it has been widely used in patients, healthy control subjects across all ages, and athletes. Pressure is recorded at the mouth during a quasi-static short (few seconds) maximal breathing. Reference: Am J Respir Crit Care Med. 2002;166:531-535.
Change in peripheral muscle strength The groups will be assessed at baseline (pre-intervention) and at the end of the training program (week 12, post-intervention). Maximal isometric muscle strength (Kg) was assessed for knee extension (Quadriceps femoris) and elbow flexion (Biceps brachii). Reference: J Am Geriatr Soc 2002; 50: 461-7.
Change in Handgrip strength The groups will be assessed at baseline (pre-intervention) and at the end of the training program (week 12, post-intervention). Isometric hand grip strength is strongly related with lower extremity muscle power, knee extension torque and calf cross-sectional muscle area. In practice, there is also a linear relationship between baseline handgrip strength and incident disability for activities of daily living. Reference: Age and Aging. 2010;39:412-423.
- Secondary Outcome Measures
Name Time Method Change in Time performed to walk 10 m distance (10mWT). The groups will be assessed at baseline (pre-intervention) and at the end of the training program (week 12, post-intervention). The 10-Meter Walk Test (10mWT) is a measure of gait speed (measurement of physical performance). The walking course consist of 14 m in a hallway: a 2 m warm-up, 10 m use for the speed measurement, and 2 m for slowing down to stop. Participants can use the assistive device (eg, cane, walker) or orthotic device (eg, ankle-foot orthosis) that they use "most often" (if any) at each time point. Reference: Phys Ther. 2010;90(2):196-208.
Change in Maximal Voluntary Ventilation (MVV) The groups will be assessed at baseline (pre-intervention) and at the end of the training program (week 12, post-intervention). This ventilatory test is a non-invasive technique and is a measure of both inspiratory and expiratory muscle endurance. The MVV is the largest volume that can be breathed in and out of the lungs during a 12 -15 second interval with maximal voluntary effort. Reference: Am J Respir Crit Care Med. 2002;166:562-564.
