Sodium balance and exercise

Media health scares treat sodium like another dietary nail in the coffin. Health professionals relentlessly warn patients about high blood pressure, a condition that can lead to cardiovascular and kidney diseases. The masses are routinely exposed to a generalized statement: be sure to minimize your salt intake. This recommendation is appropriate for the average person who overindulges in processed foods with little to no physical exertion. However, in active populations, sodium loss via sweat makes increased dietary intake necessary. Healthy, highly active adults should be sure to offset sodium losses in order to achieve optimal mental and physical performance. Continue reading

Effects of dehydration during exercise

The human body responds to exercise in various ways. Within the body, there are complicated chemical processes unfolding in response to training-induced stress. Dehydration is known to dramatically affect physical performance – as well as general health. The more specific effects of fluid loss in resistance training are usually less understood. When trying to increase musculature, or improve body composition, staying properly hydrated is a requirement.

Resistance training can stimulate internal processes to increase muscle density, in response to the applied stress on the muscular systems. However, anabolism must exceed catabolism for the subsequent synthesis of new muscle tissue. Simply put: a bucket without a bottom will never hold water. For optimal exercise prescription, athletes must promote growth and discourage wasting. Current research suggests that dehydration can disrupt the body’s muscle-building processes. Continue reading
