Look at it this way- the body type of a pole vaulter-
Lower body very strong (sprinter/ long jumper) and training should include lifting.
Upper body should be gymnast strong, but without unnecessary muscles.
Upper body- IMO should not exceed strength needed to row your own body weight and do pull ups/pull overs over and over. Creatine may get you stronger, but unneccesarily stronger if you can do pull ups over and over and have a gymnastic body type.
Lower body- Creatine has been tested over and over again to increase performance in the wieght room, but there are no studies finding it's effectiveness on quick, explosive muscle fibers greater than placebo (unless someone would link me to an article). So, hypothetically an increase in leg strength will result in more explosiveness on the runway. But i have not found any articles linking creatine use to an increase in maximum top speed down the runway, or top speed in any way really. So you may get stronger in the weightroom and find your squat max going up, but when you begin speed work, there appears in difference in training effectiveness. soo, if you want to get strong and hold the water weight in your muscles for the ladies to look at.... maybe its for you!
Now, even if there were an effectiveness, your creatine supplementation would need to be so specific (as Bel mentioned) as to structure your training around your creatine supplementation (2 weeks on, 2-3 weeks off) to see an effect. Yes, it puts on weight. But does this weight correlate with PV hieght? Possibly, if it alters the body types of young athletes and develops them before they are ready? Anyone link articles of creatine use at young ages?
So in my unproffessional opinion, but as someone who talked with many coaches, doctors, sports nutritionists, for OUR SPORT the benefits are slim if any, and require very specific training plans to see the benefits. So the only people who should consider supplementation of creatine would be the top .1% of athletes that have maximized their nutrition and training habits already.
Saying that you should supplement protien and creatine is sort of crazy, because creatine is a kind of protien and most protiens come as whey protien, only one type of protien. You know what has both these "supplements" though, and different kinds of protiens too? Tunafish! Yum....
The greater the challenge, the more glorious the triumph
