Cold and Warm Water for Performance Recovery
- Conditions
- Healthy
- Registration Number
- NCT04902924
- Lead Sponsor
- University of Applied Sciences and Arts of Southern Switzerland
- Brief Summary
The overall aim of this study is, to evaluate the effectiveness of repeated cold- and warm water immersion on performance recovery after muscle damage.
- Detailed Description
Participants perform a muscle-damage protocol, which comprises 5x20 drop jumps. After the exercise protocol is finished, the participants will undergo one of three recovery interventions. Cold-water immersion, Warm-water immersion or the control-intervention. During the exercise protocol and the recovery intervention following parameters will be assessed: Blood oxygenation, Muscle oxygenation, heart-rate, skin temperature and core temperature.
Then, performance recovery will be assessed during the following 72 hrs (in a 24 hrs interval).
At each time-point, following measurements will be conducted: vertical-jump performance, maximum voluntary isometric contraction of the m.quadriceps femoris muscle, muscle swelling and delayed-onset of muscle soreness.

- Primary Outcome Measures
Name Time Method Creatine-kinase (U/l) baseline to 72 hours using a blood sample (6 ml), creatine-kinase will be assessed
blood oxygenation (%) through recovery intervention up to 1 hour Blood oxygenation will be measured using near-infrared spectroscopy device at the finger
maximun voluntary isometric contraction (Nm) baseline to 72 hours maximun voluntary isometric contraction of the knee extensor muscle will be assessed.
vertical jump performance (cm) baseline to 72 hours maximum vertical jump performance will be measured
delayed onset of muscle soreness (units) baseline to 72 hours delayed onset of muscle soreness will be measured using a 0-10 scale, where 0 indicated no soreness and 10 indicates maximum soreness of the knee extensor muscles
muscle swelling (mm) baseline to 72 hours swelling of the knee extensor muscle will be performed using a ultrasound device.
muscle blood oxygenation (%) through recovery intervention up to 1 hour Muscle oxygenation will be measured using near-infrared spectroscopy device at the knee extensor muscle
skin temperature (°C) through recovery intervention up to 1 hour Skin temperature will be measured using a near infrared thermography camera
core temperature (°C) through recovery intervention up to 1 hour core temperature will be measured using temperature pill that will provide real time values from the gastrointestinal region
