It is found that maximum muscle mass and
strength are reached in the 20s and 30s. A gradual
decline is followed by in the middle age. The loss of
muscle mass advances from the age of 60 years.4 In
one study it is found that Sarcopenia can also be due
to the loss of motor neuron bers (denervation) and
loss and degeneration of neuromuscular junctions;
as a result, there is less muscles stimulation and the
body losses its mass.4 Till the dawn of the twenty-rst
century, sarcopenia was regarded as an age-related
decline in muscle mass with little or no emphasis on
Muscle strength and function.5
Stefanos Tyrovolas performed a study titled
“Factor associated with skeletal muscle mass,
Sarcopenia, and Sarcopenic obesity in older adults”
In this study they state that sarcopenia syndrome has
been related with the decile in type II muscle bres
which is replaced by lean mass of different kinds
of tissues that has reduced capacity of synthesize
protein, thereby leading to reduced muscle strength.
Besides, previous studies suggest that sarcopenia
correlates with poor health-related outcomes such as
physical limitations, disability, increased mortality,6-8
frailty, and poor quality of life in hospitalized and
emergency care use.8-10
The Asian Working Group for Sarcopenia
(AWGS) was formed recently, the aim of the group
was to assess the suitability of existing sarcopenia
denitions for diagnosis of populations from
Southeast Asian countries such as Thailand, China,
Japan, South Korea, Malaysia, Taiwan and Hong
Kong but there were no research found that include
Indian older adult population. According to Asian
working group of Sarcopenia, Sarcopenia is dene
as “age-related loss of skeletal muscle mass plus
loss of muscle strength and/or reduced physical
performance,” without reference to comorbidity.
Several research and studies has been performed
in the eld of sarcopenia in order to assess the clinical
components of sarcopenia but each of these studies
is focused on restricted clinical characteristics. Our
study is to screen for Sarcopenia in older adult
population and to nd its association with Physical
performance and quality of life.
Materials and methods
Our present study, aims to nd association of
sarcopenia with physical performance and quality
of life in older adults. This study was observational
study. In this study, 200 subjects diagnosed with
sarcopenia of age 60 or 60+ year in the study
fullling the inclusion criteria. The inclusion criteria
comprised of SARC-CalF score more than 11/20
and Jamar handheld dynamometer scoring <26kg
for men and <18kg for women indicates Sarcopenia
according to AWGS criteria, age group of 60 or 60+
year and subject willing to participate whereas the
exclusion criteria comprised of older adult with
congenital deformity, neurological conditions like
Stroke, traumatic brain injury, Spinal cord Injury,
Parkinsonism and individual with recent Fracture.
Subject were selected on the basis of simple sampling
method. A written informed consent is taken from
the subject in the language best understood by them.
Purpose of the study and procedure are explained to
the subjects. An assessment was taken to record their
demographic details and other parameters.
Diagnosing sarcopenia with the help of SARC-
CalF and jamar handheld dynamometer. The
SARC-CalF questionnaire is a screening tool
that can be easily apply by clinicians to identify
probable sarcopenia. The SARC-CalF scale contains
six objects: 1. Strength; 2. Walking assistance; 3.
Rising from a chair; 4. Climbing stairs; and 5. Falls;
6. Calf circumference, with scores between 0 and
2. According to the 2019 Asian Working Group for
Sarcopenia (AWGS) criteria, calf circumference
cutoff value were 34 and 33 for men and women,
respectively. When a score obtained is above the
cutoff value, calf circumference is scored as 0; if the
score is below the cut-off value, the score is 10. A
positive screening for sarcopenia is indicated when a
score of ≥11 points is obtained. To evaluate the hand
grip strength of the subjects, Hydraulic type Jamar
handheld dynamometer is used. Standard positioning
recommended by AWGS 2019 is sitting with 90°
elbow exion for the Jamar dynamometer. As per
the recommendation of AWGS, hand grip strength is
measured by taking the maximum reading of atleast
2 trials using either both hands or the dominant hand
in a maximum-effort applied by the subject and
cutoffs for low muscle strength of handgrip is <28.0
