Dehydration Reduces Posterior Leg and Trunk Flexibility and Increases Stiffness in Male Collegiate Age Runners

This blinded study of collegiate runners has shown flexibility and stiffness are impaired in a dehydrated state versus a euhydrated state, by as much as 11% and 43%, respectively. High levels of stiffness and lack of flexibility have previously been linked to increased risk of injury within the posterior leg as well as impeded athletic performance.
