Creatine loading following by 22-27 weeks of maintenance (3g creatine and 7g glucose) followed by another loading phase prior to competition failed to significantly improve sprint performance or prolonged swimming performance. There was a decline in growth hormone associated with the loading phase, but this was attenuated with maintenance and IGF-1 was unaffected.
