Time-under-tension factors in the tempo of one repetition multiplied by the number of repetitions. For example, a tempo of 2010 represents three seconds per repetition multiplied by eight repetitions in a set, which results in a time-under-tension of 24 seconds. As with repetition ranges, there are general time-under-tension ranges that have impacts on particular physiological capabilities.
