However, little is known about the prolonged effects of this supplement on neuromuscular adaptations to strength training. Objectives: The present study aims to analyze the effects of acute and chronic caffeine intake on neuromuscular adaptations to strength training, according to sex (men vs. women) and type of exercise (bench press vs. squat), as well as fatigue perception, mood state, and potential side effects in older adults.","overall_status":"Active Not Recruiting","phases":[],"study_type":"INTERVENTIONAL","sponsor":"Alberto Pérez-López","enrollment":48,"countries":["Spain"],"start_date":"2024-01-14","completion_date":"2026-07-30","last_update_date":"2026-05-06","source_url":"https://clinicaltrials.gov/study/NCT06618261","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
