What happens to muscle tension during incomplete tetanus?

During incomplete tetanus, muscle tension reaches a much higher level due to a rapid series of stimulus events that lead to increasingly stronger muscle contractions without full relaxation between stimuli. In this state, the muscle is stimulated repeatedly before it has a chance to completely relax, resulting in a summation of contractions. This progressive increase in tension is attributed to the cumulative effects of calcium ions in the muscle fibers and the buildup of tension from each individual contraction not fully dissipating before the next occurs.

This results in a sustained contraction, where muscle fibers contract more forcefully with each successive stimulus up to a certain point. Incomplete tetanus is an important physiological process that allows for greater muscle force generation during activities requiring sustained effort, such as lifting or repetitive movements.
