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

Outcomes
Primary Outcomes

RPE will be assessed using a BORG scale (6-20)
Skin temperature
Time Frame: 60 minutes
Skin temperature of the neck, right scapula, right dorsal hand, right frontal thigh, right shin are assessed in °C using thermocouples (iButtons)
Vertical Jump
Time Frame: 72 hours
Vertical Jump will be assessed in cm with the Just Jump Plate
Cardiovascular measurements
Time Frame: 60 min
Heart rate will be measured in beats per minute and bloop pressure will be measured in mm/Hg using an blood pressure monitor
Oxygenation of the right thigh muscle
Time Frame: 60 min
Oxygenation of the right thigh muscle will be assessed in % using a near infrared spectometer.
Core temperature
Time Frame: 60 minutes
Core temperature will be assessed in °C via the ear
