Unformatted text preview: authors have suggested that the initial intracellular swelling may be a preparatory phase of compensatory hypertrophy in response to resistance training. Also, the increased water retention within the intracellular compartments may contribute to increased force production by increasing interstitial leverage advantage. In summary, it appears that most reports of adverse effects regarding Cr supplementation have been anecdotal. When studies employ research designs that include control groups and blinding, there appears to be no consistent finding of any detrimental effects of Cr supplementation in normal, healthy individuals.

Conclusion In general, recent studies are similar to the older literature discussing Cr supplementation; however, better statistical analyses utilising repeated measures designs and the examination of interaction terms are much more common in the newer literature. Other improvements in methodologies include double blinding, greater varieties of subjects (e.g. female, older) and better attempts at understanding the mechanisms responsible for improved performances. Basically, Cr seems to provide the most beneficial effects for sport performance when the activity involves repeated, short bouts of high-intensity exercise. It appears that athletes who perform in sports that are most similar to this type of activity have the greatest benefit from Cr supplementation. Sports like football, soccer, squash and lacrosse are the types of sport most often involving Cr usage. Part of the documented findings associated with Cr supplementation seem to be related to the outcome measures that are selected for any particular study. If dynamic or isotonic peak force is assessed, it generally appears that Cr supplementation can provide a benefit. However, if isoki...
