INTRODUCTION
• Handgrip strength is a quick and simple measure of muscular
function that can be measured feasibly in clinical and field
settings.
• Its practicality has made it an attractive additional criterion for the
diagnosis of sarcopenia in clinical settings.

PURPOSE
• The purpose of this study was to examine the relationship
between maximal handgrip strength and other common
measures used to assess physical health in older persons.
METHODS
• Grip strength ranged from 9.7 to 53.3 kg (mean±SD = 30.6±12.3
kg).
• The table and figures below presents the correlation of handgrip
strength to various measurements.

SUBJECTS:
Thirty-six healthy older men and women
(age: 71.3±6.1 y; BMI: 27.9±5.2 kg∙m2) completed tests of muscular function
including maximal isometric grip
strength (GRIP) and timed sit-to-stand.
BODY COMPOSITITON:
Body composition was assessed by
Dual-energy X-ray absorptiometry
FASTED BLOOD DRAW:
Fasting serum samples were collected
to evaluate circulating albumin and
hemoglobin concentrations.
STATISTICS:
Pearson’s correlation coefficients were
computed to assess the relationship
between handgrip strength and other
measures of physical health and
function.

BACKGROUND: Handgrip strength is a quick and simple measure
of muscular function that can be measured feasibly in clinical and
field settings. Its practicality has made it an attractive additional
criterion for the diagnosis of sarcopenia in clinical settings. However,
it is unknown how handgrip strength performance relates to other
common measures of physical health and function in healthy older
adults. PURPOSE: The purpose of this study was to examine the
relationship between maximal handgrip strength and other common
measures used to assess physical health in older persons.
METHODS: Thirty-six healthy older men and women (age: 71.3±6.1
y; BMI: 27.9±5.2 kg∙m-2) completed tests of muscular function
including maximal isometric grip strength (GRIP) and timed sit-tostand. Body composition was assessed by Dual-energy X-ray
absorptiometry and fasting serum samples were collected to
evaluate circulating albumin and hemoglobin concentrations.
Pearson’s correlation coefficients were computed to assess the
relationship between handgrip strength and other measures of
physical health and function. RESULTS: Grip strength ranged from
9.7 to 53.3 kg (mean±SD = 30.6±12.3 kg). Pearson’s correlation
coefficient for handgrip strength and other common measures of
physical health and function are as follows: Sit to stand: r=.34; Lean
soft tissue (kg): r=.83; Arm lean mass (kg): r=.84; Skeletal muscle
index: r=.74; Albumin (g/dL): r=.06; Hemoglobin (g/dL): r=.36.
CONCLUSIONS: Maximal handgrip strength demonstrated a
significant and moderate to high relationship with all variables with
the exception of albumin. These data suggest that the handgrip
strength may be related to physical health and nutritional status of
older men and women in this study. PRACTICAL APPLICATION:
The salient features of the handgrip strength test are the ease of
measurement, portability of the testing device, minimal time required
for testing, and relationship to other important measures of muscle
strength and function. The observed positive relationship between
handgrip strength and other measures of muscle mass, function,
and health, provide support for the use of handgrip strength as an
additional method to monitor muscle function by clinicians or
personal trainers.

ABSTRACT
Figure 2. Correlation between
skeletal muscle index and grip
strength.
Handgrip Strength (kg)
• Maximal handgrip strength demonstrated a significant and
moderate to high relationship with all variables with the exception
of albumin.
• These data suggest that the handgrip strength may be related to
physical health and nutritional status of older men and women in
this study.
PRACTICAL APPLICATIONS
• The salient features of the handgrip strength test are the ease
of measurement, portability of the testing device, minimal time
required for testing, and relationship to other important
measures of muscle strength and function.
• The observed positive relationship between handgrip strength
and other measures of muscle mass, function, and health,
provide support for the use of handgrip strength as an
additional method to monitor muscle function by clinicians or
personal trainers.
