What type of resistance training maintains constant muscle tension?

Isotonic exercise is the type of resistance training that maintains constant muscle tension. During isotonic exercises, a muscle contracts and shortens while overcoming a load, allowing for consistent tension during the movement. This can be seen in exercises like weightlifting, where you perform both the lifting (concentric phase) and lowering (eccentric phase) movements with a constant load.

In contrast, isometric exercises involve muscle contractions without any change in muscle length, resulting in no movement of the joints. Dynamic exercises are more general and may not specify the constant tension aspect, while isokinetic exercises involve variable speed and resistance, requiring the effort to match the resistance throughout the movement's range. Therefore, isotonic exercises are particularly effective for building strength and endurance by ensuring that muscle tension is maintained throughout the entirety of the movement.
