Recovery is an important aspect of any intense sport or physical conditioning program. However, many athletes train extremely hard without giving their body time to recover properly, which can lead to burnout and poor performances. Shortening recovery time results in a competitive advantage.
The ability of the body to clear or remove lactic acid (aka Lactate or H+) from the tissues is one of the limiting factors in exercise recovery. Cold therapy speeds this process up by causing superficial blood vessels to constrict, effectively “squeezing” these metabolites out of the muscles and tissues into the deeper blood vessels where they are diluted and neutralized by the body.
The reduction of swelling (aka inflammation or oedema) caused by intense exercise is also a limiting factor in recovery time. Swelling is controlled by the lymphatic system rather than the circulatory system and relies on mechanical forces such as gravity and external pressure to move its contents. The buoyant water pressure and massage delivered by the Coldtub™ provide these external forces, speeding up recovery time.
Reducing sympathetic nervous system activity is another important factor in exercise recovery. Intense exercise stimulates the sympathetic nervous system to increase adrenaline production, which if left unchecked can cause the athlete to ignore the signs of fatigue, causing them to burn out or get injured. Put simply, cold therapy dampens the adrenaline rush so the athlete feels like taking a needed break from activity.
