Speed in strength training can mean several things: the load moves quickly, or you intend to move it quickly even when it does not. Research on older adults explores these differences, but the evidence does not reduce to “faster is always better”.

What the research found

A systematic review and meta-analysis comparing maximal-intent and slower resistance exercise in older adults found some task-specific signals but no clear pooled superiority across outcomes. The available studies were few, heterogeneous and often methodologically limited. [1]

Intending to move quickly is not the same as moving recklessly or using uncontrolled technique. The review does not justify a blanket instruction to make every repetition fast.

Clarify the instruction first

If a programme includes a fast lifting intent, ask what that means for the specific exercise and how control is maintained. Choose a suitable setup and guidance. Do not turn a research term into permission to rush unfamiliar movements.

Putting it into perspective

Two people may hear “move quickly” and do very different things. One may apply purposeful effort while maintaining control; another may rush the whole movement. Clarifying the instruction with appropriate guidance matters more than borrowing a phrase from a paper and applying it without context.
