Proper hydration vital for peak performance

The human body is made up of approximately 70 percent water, so you would think we should have a camel-like ability to go for extended periods of time without drinking any. However, as the slight thirst you may be feeling this very moment indicates, this obviously isn't the case.

This need for water is especially strong while we're exercising, when we're losing a great deal of fluids through our sweat. The need for replenishment -- and even the perceived need for it -- can have a significant effect on our performance in the gym, say researchers from Chicago State University. There, it was discovered that as little as three percent dehydration decreased upper and lower body power by seven and nineteen percent respectively. What's more, study volunteers reported a 70 percent increase of perceived fatigue at this same degree of dehydration.

For peak performance in the gym, be sure to stay hydrated throughout the day. Remember: when you feel thirsty, you're already in the very early stages of dehydration. Aim to avoid letting this thirst occur by regularly sipping on water.
