When the biceps contracts the triceps relaxes slowly. It happens when your arm is bent.
When triceps are in contraction (flexion), automatically biceps should be in extension. Biceps and triceps are antagonist in function.
The tricep contracts and the bicep relaxes.
Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
The bicep muscle. The tricep contracts to straighten the arm as the bicep relaxes.
When the bicep contracts, the tricep relaxes. These pair of muscles are known as antagonists which means as one contracts, the other relaxes and vice versa.
The bicep contracts while the tricep relaxes
The Bicep muscle (one on top) is contracting The Tricep muscle (one below) if relaxing The Bicep and Tricep muscles are antagonistic- they work as opposites, so when one contracts, the other relaxes.
The tricep
When the bicep contracts the triceps relax
muscles work in pairs so when the bicep relaxes the tricep contracts, these actions create elbow extention (arm lowering) creating an objuce angle- lowering stage in a bicep curl
When lowering arm biceps relax and triceps contracts. When one contracts the other relaxes when you move it forward and downward.
