- Enhance body’s ability to achieve high-intensity work (perfect for those sprint sessions) (The American College Of Sports Medicine, 2000)
- Improve ATP energy breakdown (Katz & Westerblad, 2014).
- ATP are packets of energy that your body uses in order to function…so this is a very, very good quality of creatine
- Improves anaerobic capacity (again, bettering your sprint sessions, allowing you to push harder during your short-term, all-out sprints)
- Improves glucose tolerance, allowing for more available energy during your endurance sessions
- Improve bone healing- very important for endurance runners to avoid stress fractures
- Improve muscle mass and muscle status (I know a lot of triathletes want to be lean, but it’s also good to have muscle bulk to increase power output)
- Increases muscle strength and cross-sectional area
- Increases power
- What you need during your final sprint to the finish line; maximal velocity and force production (Volek et al., 1997)
- Decreases time to fatigue
- More reps, more sets, or longer runs; you choose
- Breaks you out of a plateau
- Decrease in blood lactate post-exercise compared to non-creatine subjects (Izquierdo et al.)
- Requires a loading phase
- Does not enhance recovery (decreases time to full recovery)
- Unfortunately, according to a meta-analysis by Rawson, Conti, & Miles (2007) on contrary to previously believed methodologies, creatine doesn’t help decrease time of musculoskeletal recovery
- Weight gain due to water retention in the intramuscular space
- Potential for kidney damage, bloating, and reduced blood plasma if you take too much (>20g creatine for >5 days) (Barrette, 1998).
