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.

Repeated cold-water immersionrepeated cold water therapyIn this arm, the participants undergo repeated cold water immersion at 10°C for 2 x 5 min. Between the immersion, a break will be conducted 2.5 min. Participants will be immersed up to the iliac crest
Repeated warm-water immersionrepeated warm water therapyIn this arm, the participants undergo repeated warm water immersion at 40°C for 2 x 5 min. Between the immersion, a break will be conducted 2.5 min. Participants will be immersed up to the iliac crestParticipants will be immersed up to the iliac crest.
ControlcontrolIn this arm, the participants undergo the control intervention which comprises to remain seated for 12.5 min. The participants, that will perform the muscle damaging protocol under hypoxia will also be treated with the control condition.
Primary Outcome Measures
NameTimeMethod
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
