Clinical Trial Summary

This study investigates the effects of whole-body cryotherapy vs. cold-water immersion after a muscle damage protocol.

Description:

In this study the effects of a single- or multiple whole body cryotherapy (-135°C for max. 2 minutes) vs. cold water immersion (10°C for 15 min) and a passive control group (20 min supine position) are compared. These effects are examined after a muscle damage protocol of the frontal thighs (3 x 30 jumps). The objective recovery parameters are vertical jump, maximum voluntary contraction of the anterior thigh muscle, heart rate, blood pressure, skin-core body temperature and the oxygen saturation of the thigh muscles. Subjective recovery parameters are the local muscle soreness details and the general exhaustion details. The parameters are directly and 24, 48 and measured 72 hours after exposure. The aim is to elicit the effects of whole body cooling to make recommendations to. The current scientific knowledge situation calls for further studies to whole body cooling.

Related Conditions & MeSH terms

• Cold

Intervention

Device:
• Kryosauna Space Cabin
The whole body cryotherapy device is able to generatue temperatures up to -195°C for 3 minutes. In this study, we generate temperatures of -135°C for 2 minutes as proposed in the manual. The participant will enter the cabin in cold-resistant shoes and will remain in standing position during the whole procedure. The cold temperature is generated by vaporization of liquid nitrogen.

Other:
• cold water tub
The tub will be filled with cold water up to the sternal level of the participants. Adding ice will ensure a constant temperature. The participant will sit inside the tub during the whole procedure.
