Burke Research has shown aging is associated with a decline in muscle phosphocreatine levels. This decline is more than likely due to the age-related decline in the size and number of fast twitch fibers, which store most of the creatine. To determine whether creatine supplementation may affect this age-associated decline in muscle creatine levels, researchers compared a group of test subjects whose average age was 31 to a group of older individuals with an average age of 58. Participants performed three bouts of leg-extension exercises seven days apart. The first two bouts lasted two minutes each, and a third bout continued until exhaustion; all bouts were separated by three minutes of recovery. During the placebo trial, the older-aged group had a lower resting level of phosphocreatine and wasn't able to resynthesize phosphocreatine after exhaustive exercise as fast as the younger group. After creatine supplementation, resting phosphocreatine increased 15% in the younger group and 30% in the middle-aged group. Due to creatine supplementation, the older-aged group also increased their ability to resynthesize phosphocreatine by about 30%.
