What the study found
The mixed supplement improved several jumping, agility and repeated-sprint measures, but did not improve sprinting or aerobic performance in the reported tests.
Participants and protocol
Thirty trained basketball players were studied in a double-blind placebo-controlled design. The supplement contained caffeine, creatine, beta-alanine, citrulline malate and amino acids.
What this cannot establish
The effects cannot be attributed to one ingredient. Basketball tests and a single dose do not establish a marathon benefit, long-term effect or personal supplement recommendation.
