Verified step by step guidance

Understand the different types of muscle contractions: Isotonic, Isometric, Tetany, Treppe, and Concentric.

Isotonic contractions involve a change in muscle length while maintaining constant tension, either shortening (concentric) or lengthening (eccentric).

Isometric contractions occur when muscle tension is generated without any change in muscle length, meaning the muscle does not shorten or lengthen.

Tetany refers to a sustained muscle contraction due to rapid stimulation, while Treppe is the gradual increase in muscular contraction following rapidly repeated stimulation.

Concentric contractions are a type of isotonic contraction where the muscle shortens as it contracts. Based on these definitions, identify which type of contraction involves increased tension without changing muscle length.
