NOTE: This lab can be completed as written. As an addition, you can also test your dominant forearm for comparison.
NOTE: The Grip Sensor automatically measures the room air pressure in PSI (approx 14 PSI). All your data will start at a baseline of 14 PSI. When you measure V2-V1 – this will give you the correct values for your grip force because it is measuring the difference in the position of the cursors.
To determine the relationship between the EMG activity and the grip strength in your dominant arm.
REMEMBER TO ONLY USE YOUR FINGER TIPS.
Put your data into a data table or into the Journal. You can open and close the Journal by clicking the "Notebook" icon.
To observe the relationship between the strength and length of contraction time of a muscle and EMG activity.
REMINDER – Do NOT use your whole fist – just use your fingertips when squeezing the bulb. Hold your thumb out.
