What does the evidence say about Citrulline Exercise Performance Randomized Trial?

Updated June 2026

Quick Answer

Citrulline Exercise Performance Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: Strategies that support repeated high-intensity sprint performance are of considerable interest in competitive sprinting and team sports; however, evidence regarding acute citrulline malate (CM) supplementation during recovery intervals remains limited.

Key Takeaways

  • 01Strategies that support repeated high-intensity sprint performance are of considerable interest in competitive sprinting and team sports; however, evidence regarding acute citrulline malate (CM) supplementation during recovery intervals remains limited. [Yamanaka R (2026)]
  • 02This study examined the effects of acute CM supplementation on repeated 100 m sprint performance and rating of perceived exertion (RPE) in trained sprinters. [Yamanaka R (2026)]
  • 03Through its involvement in NO-related pathways, L-ARG supplementation has been associated with changes in vascular function and blood flow, which may influence exercise-related physiological responses (,–). [Uçar Halil (2026)]
  • 04However, the findings across these studies remain inconsistent, and conclusive evidence supporting clear performance or recovery benefits has yet to be established. [Uçar Halil (2026)]
The current Migaku evidence database contains 2 reusable source documents for Citrulline Exercise Performance Randomized Trial. This answer focuses on benefits, uncertainty, and practical interpretation. - Strategies that support repeated high-intensity sprint performance are of considerable interest in competitive sprinting and team sports; however, evidence regarding acute citrulline malate (CM) supplementation during recovery intervals remains limited. [Yamanaka R (2026); evidence level 2] - This study examined the effects of acute CM supplementation on repeated 100 m sprint performance and rating of perceived exertion (RPE) in trained sprinters. [Yamanaka R (2026); evidence level 2] - Through its involvement in NO-related pathways, L-ARG supplementation has been associated with changes in vascular function and blood flow, which may influence exercise-related physiological responses (,–). [Uçar Halil (2026); evidence level 4] - However, the findings across these studies remain inconsistent, and conclusive evidence supporting clear performance or recovery benefits has yet to be established. [Uçar Halil (2026); evidence level 4] - No significant sequence effect was detected (= 1.08,= 0.393, ηp= 0.213), and no significant period × sequence interaction was observed (= 1.04,= 0.430, ηp= 0.206), indicating no statistically significant evidence of meaningful carryover effects and supporting the adequacy of the 72-h washout period. [Uçar Halil (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
