Breathe better, lift heavier? new study tests breathing training for CrossFit athletes
NCT ID NCT06807957
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether training the muscles you use to breathe in can improve strength and exercise performance in amateur CrossFit athletes. 94 healthy adults aged 18-60 who do CrossFit will either do breathing training with a special device plus their usual workouts, or use a fake device. Researchers will measure breathing muscle strength, exercise test times, and how tired athletes feel after 8 and 12 weeks.
