ContrastSpa Duo

Your optimum contrast bathing setup

Nowadays, most strength and conditioning coaches have a preference for either contrast therapy i.e. alternating hot and cold or for cold water immersion alone. Many high profile clubs including Manchester City FC and Fulham FC utilise contrast bathing and CET have supplied them the ContrastSpa Duo option.

The Australian Institute of Sport are also strong supporters of contrast bathing. They believe that you should spend 6-12 minutes doing contrast bathing of which 6-10 of those minutes should be in the cold as they contend that the main benefits come from the cold-water immersion. And it is important to finish in cold.

Contrast bathing works by promoting rapid alternation between vasodilation and vasoconstriction, which causes a 'pumping' action in the peripheral circulation by using temperature rather than manual methods. Heat stimulates circulation bringing in fresh blood, lymph, oxygen, water and nutrients while cold contains the inflammatory response and expels stagnant fluid and waste products.

Benefits of Contrast Bathing

Contrast bath

The CET ContrastSpa Duo setup includes one cold CryoSpa and one hot ThermoSpa with complementary steps located between the spas to facilitate easy access.

In regards to treatment, you decide the temperature of both spas. For cold water immersion in the CryoSpa, it is typical to set the temperature between 10°C and 15°C. With the ThermoSpa we have found that most people prefer to set the temperature between 33°C and 35°C.

And you determine how many times your athletes alternate between hot and cold. Most strength and conditioning coaches, physios etc. prefer to alternate each player 3-4 times between the two temperatures.

Like the CET CryoSpa, the CET ThermoSpa will hold up to 4 players and the placement of the 20 massage jets are patent protected. Each jet has been strategically placed so that it targets a specific muscle in the body and gives optimal benefits to each player.

Whether solely using our CryoSpa Ice Baths or our Cryo-Thermo ContrastSpa Duo Setup, early treatment is DESIRABLE to ensure that your athletes recover faster and repeatedly perform at a high level.

All players need to train hard and recover well, and using hydrotherapy is a key factor in this as it will lead to an Enhanced Performance which will lead to MORE wins in the long-term!
