Primary purpose: TREATMENT

Brief summary: The goal of this clinical trial is to investigate the effectiveness of post-exercise massage and cold-water immersion compared to control in young elite swimmers. The main questions it aims to answer are:

* Is post-exercise techniques effective for recovery of the movement variability, , myotonometric, ergometric and perceptive parameters after fatigue?
* Can neuromuscular fatigue protocols impair movement variability, myotonometric, ergometric and perceptive parameters?
* What tests are reliable to assess different aspects of swimmers' recovery?

Researchers will compare massage and cold-water immersion to control and to each other to see if recovery is antecipated. They will also compare an in-water and an out-of-water fatigue protocol to see if they are effective and can be used in different settings.

Participants will:

* Perform test and retest sessions to assess movement variability, myotonometric, ergometric and perceptive parameters.
* Perform an in-water fatigue protocol consisting of 8x100m front-crawl sprints
* Receive three recovery strategies in a randomized order (massage, cold-water immersion and control (i.e. rest)
* Answer a questionnaire regarding ther beliefs and preferences for recovery.


Eligibility criteria: Inclusion Criteria:

* male and female athletes
* between 15 and 30 years old
* no injury over the last month (any complaint that prevented the athlete from training or compete at least once)

Exclusion Criteria:

* use of pain killers at least 24h before study participation
