Get a grip by doing the EMG-Grip Strength lab and teach you students about recruitment and fatigue.
Then move on to Human Muscle Twitch and show them the concepts of threshold, summation, and tetanus.
And, finally, the Antagonistic Muscle lab shows the concept of how muscles work in opposing pairs or groups.
These labs can be completed in any order and will give you and your students activities to do to demonstrate these sometimes confusing topics.
