Creatine can help improve muscle strength and power, and creatine uptake can be increased with electrolytes. A study published in the Journal of the International Society of Sports Nutrition suggests stacking these supplements might improve repeat sprint performance for cyclists.
Twenty-three male recreational cyclists were tested before and after supplementing with creatine and electrolytes for 6 weeks. Each test involved 5 sets of 15-second sprints with 2 minutes of recovery between sets. Compared to pre-supplement testing, peak power increased an average of 4% after subjects supplemented with creatine and electrolytes, and mean power increased about 5%.
