With regards to the creatine phosphate resynthesis question,
the recovery is
dependent on the cellular pH. There is a great 31MR study by Arnold et al. that all physiologists need to read. Arnold D.L. et al. J. Magn. Reson. Med. 1(3):307-315, 1984. Your estimate of a half time to recovery for exercise conditions that are not associated with acidosis is correct. However, for durations to fatigue approximating 4 min, there will be acidosis and you will have a half time to recovery of 2 to 3 times as long. The bottom line though is that this topic is poorly (inadequately)researched, yet it is of vital importance to intermittent intense exercise performance!! Rob Robergs
