Unformatted text preview: the use of anthropometry to estimate muscle cross-sectional area and the increased error associated with this technique. Chronic Cr administration during this study had a significant ergogenic effect upon 1RM strength and fat-free mass when compared with periodised resistance training alone. Sports Med 2005; 35 (2) The Effects of Creatine in Sport and Exercise Brenner et al.[32] reported similar findings as those presented by Becque et al.,[31] using 16 female collegiate lacrosse players. A similar loading and maintenance programme to that used by Becque et al.[31] resulted in a greater increase in 1RM measures for the Cr group (significant group × time interaction) and reduced skinfold measures when compared with the placebo group. The influence of Cr on measures of performance are more controversial when collegiate football players are used as the experimental group. Wilder et al.[26,27] reported that neither low-dose (3 g/day) nor high-dose (20 g/day for 7 days followed by 5 g/day) Cr supplementation during a 10-week periodised strength training programme for collegiate football players had any additional effect on strength gains when compared with a control group. Both groups had significant strength increases over time but there was no significant group by time interaction. However, utilising a similar study group, Bemben et al.[28] found that a 9-week periodised strength training programme combined with Cr supplementation (20 g/day for 5 days followed by 5 g/ day for the rest of the study) with red-shirt collegiate football players resulted in significantly greater improvements in strength, peak torque, and anaerobic power and capacity as assessed by the Wingate protocol when compared with both a placebo and control groups.[28] The higher maintenance dose used in the Bemben et al.[28] study may have been a contributing factor to the significant differences observed post-supplementation. Another possible explanation for the different findings of these two research groups may be linked to the college experience of the two groups of subjects. In the two Wilder et al.[26,27]...
