Rest periods in strength training: do they boost performance in fighters?
NCT ID NCT07653425
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 28 amateur striking combat athletes (boxing, kickboxing, karate) who did a 6-week strength program. One group did all reps in a row, the other took short rests between reps. Researchers measured jump height, throw distance, and lifting speed to see which method worked better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- resistance training (traditional vs. cluster)
- What this could lead to
- If cluster training proves superior, it could help combat athletes design more effective strength programs.
- What could go wrong
- This is a small, completed study in healthy athletes. Results may not apply to other populations or sports.
