NCT04541901

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.

Outcome Measures

Primary Outcomes (1)

  • Movement variability

    Obtained from time series of biomechanical data expressed as degrees of shoulder and elbow flexion, and ergometric variables (i.e. pace, stroke frequency and average power) executed during a simulated out of water swim ergometric test to understand the impacts of fatigue on movement and explore changes during recovery. Measured at baseline, post-fatigue and post-interventions. Joint angles time series of shoulder and elbow flexion and ergometric variables were aggregated using mean, standard deviation and variation coefficients for data analyses.

    From enrollment to the end of crossover treatments at 6 weeks

Secondary Outcomes (6)

  • Swim-related perceptions

    From enrollment to the end of crossover treatments at 6 weeks

Study Arms (3)

Massage

EXPERIMENTAL

12 minutes of effleurage and petrissage on the upper limbs administered after fatiguing exercise in the swimming pool

Other: Massage

Cold-water immersion

EXPERIMENTAL

12 minutes of cold-water immersion at the shoulder level with water temperature between 11 to 15°C

Other: Cold water immersion

Control

NO INTERVENTION

12 minutes of rest. The athletes are free to sit or walk around the place but are advised to refrain from exercise in and out of the pool.
