Overview
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.

Outcomes
Primary Outcomes
Maximum Voluntary Isometric Contraction (N)
Time Frame: baseline to 72 hours
maximun voluntary isometric contraction of the knee extensor muscle will be assessed.
Delayed Onset of Muscle Soreness (DOMS)
Time Frame: 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
Time Frame: baseline to 72 hours
swelling of the knee extensor muscle will be performed using a ultrasound device.
Creatine-kinase (U/l)
Time Frame: baseline to 72 hours
using a blood sample (6 ml), creatine-kinase will be assessed
Muscle Blood Oxygenation
Time Frame: through recovery intervention up to 30 minutes
Muscle oxygenation saturation (SmO2) of the knee extensor muscle will be measured using near-infrared spectroscopy device. Oxygenated haemoglobin (oxyHb), deoxygenated haemoglobin (deoxyHb) and total haemoglobin (TotHb) were assessed in arbitrary units and SmO2 was calculated as oxyHb/TotHb x 100 value (%)
Skin Temperature (°C)
Time Frame: through recovery intervention up to 30 minutes
Skin temperature will be measured using a near infrared thermography camera
Core Temperature (°C)
Time Frame: through recovery intervention up to 30 minutes
core temperature will be measured using temperature pill that will provide real time values from the gastrointestinal region
