About this trial
The primary purpose is to compare the effects of creatine supplementation (bolus ingestion of 5 grams vs. 3 grams) during 16 weeks of resistance-band training on measures of body composition (i.e., whole-body lean tissue mass, total body water), arm and leg muscle thickness (growth), muscle performance (i.e., power, strength, endurance) and functional ability (i.e., walking speed, balance).
A secondary purpose of this research is to examine the effects of bolus ingestion of creatine (5 grams) compared to intermittent ingestion of creatine (2 x 2.5 grams) during 16 weeks of resistance-band training on measures of body composition (i.e., whole-body lean tissue mass, total body water), arm and leg muscle thickness (growth), muscle performance (i.e., power, strength, endurance) and functional ability (i.e., walking speed, balance).
