much force as possible being careful to squeeze only once. Record the resultant scale
reading.
4.
Allow three trials with each hand, right and left hand alternating. There should be a brief
pause of about 10 to 15 seconds between each trial to avoid excessive fatigue. Record
the amount registered at each trial, but use only the highest recorded for each hand.
Compare your findings with the averages shown in Table 1 and 2.
Measurement :
1.
Holding device in one of your hands, turn the knob to adjust the grip range until the
second joint of your forefinger is bent through 90 degrees.
2.
Stand upright and relaxed, extend your arms downward, and grip the device and exert full
force without letting your arms touch your body. During the measurement, do not wave
the device.
3.
Read the value displayed on the dial face and record it.
l
Turn the pointer to set the pointer zero again.
Methods :
1.
Have the subject hold the spring hand dynamometer with scale facing away from his face.
2.
Adjust the grip size until the joints of the subject’s finger same approximately on a plane
perpendicular to the scale plate.
3.
When the adjustment is optimal, the subject will sense he can comfortably exert his
maximum grip.
4.
Move the pointer lever to zero with your finger.
5.
Force Range : Measures from zero to 100 kg (220 pound).
6.
Resolution and precision
Measurement graduations are every five pounds (within the red inner ring) and every 0.5
kg (whthin the black outer ring).
STRENGTH NORMS :
Grip strength, measured with hand grip dynamometer, correlates with overall upper body strength
and is an easy, safe test to perform, A good grip is linked to higher lean body mass, lower risk
of disability in old age, and increased longevity. Compare your test results with the norms shown
below.
