Losing just 2% of your body weight through perspiration can have a negative impact on athletic performance. Do you have a strategy for keeping up with hydration needs? A study of 289 competitive athletes published in The Journal of Sports Medicine and Physical Fitness shows a tendency to drink less than what’s recommended.

Subjects participating in international, national and regional events drank an average of 0.25 liters of water per hour. Analysis of survey results found that 23 subjects met or exceeded the recommended fluid intake while 150 drank less than the average reported in the surveys.
