The aim of this study was to investigate the effect of eight weeks of TRX Suspension Training (TST) on serum levels of neuromuscular growth factors and functional indices in elderly men with sarcopenia.
Design
In this research, a semi-experimental design was used (two groups in the form of a pretest and a post-test).
As a result of the coronavirus pandemic, some participants refused to participate in the training protocol. Therefore, those who were willing to participate in the exercise program were assigned to the training group.
Settings and conduct
Before starting the protocol participants were trained how to do the exercises. The training programs included 8 weeks, three sessions per week, about 60 min per session including warm up and cool down. ِDue to the coronavirus pandemic exercises were done outdoors. Serum concentrations of muscle growth markers, anthropometric and body composition indices, and functional tests were evaluated at baseline and after 8 weeks.
Participants/Inclusion and exclusion criteria
Inclusion criteria included: 1- age more than 65 years; 2- handgrip strength lower than 32Kg, and SMM/height2 lower than 9.2 kg/m2; 3- being sedentary for at least 1 year (didn’t have more than 1h exercise per week)
Exclusion criteria included: 1- cardiovascular or pulmonary diseases, diabetes, Joint and muscle problems, and Mental and cognitive disorders; 2- involvement in any extra exercise training programs; 3- not interested in continuing or changing in personal life schedule.
Intervention groups
Participants in the Control group were asked to continue their routine lifestyle. The training group executed the TRX Suspension Training for 8 weeks.
Main outcome variables
Myostatin levels; Follistatin levels; GDF-15 levels; CAF levels; Handgrip strength; Gait speed; Time up and go (TUG); Chair stand speed; Standing balance.

Description of health condition studied
With aging, there is an inevitable progressive loss of muscle mass and strength called sarcopenia that is associated with the risk of impairment in physical ability which could lead to consequences such as falls, fall-related injuries, hospitalizations, and even mortality.
