Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are:
Do cold water immersions reduce muscle fatigue and improve performance more effectively than hot water immersions? What is the optimal timing and duration for these recovery interventions to maximize their effectiveness?
Researchers will compare:
Cold Water Immersion (CWI) Hot Water Immersion (HWI) No Immersion (NI) Thermographic Immersion (TI) based on individual thermal profiles
Participants will:
Undergo thermographic assessments to determine their thermal profiles. Perform physical tests such as isometric strength tests, countermovement jumps (CMJ), and squats with 50% body weight.
Complete wellness questionnaires to assess their subjective recovery and fatigue levels.
Provide blood and urine samples for biomarker analysis. Participate in recovery interventions (CWI, HWI, or TI) based on their assigned group.

RANDOMIZED
CROSSOVER
Participants are randomly assigned to different intervention sequences, ensuring each participant receives all interventions in a random order. The study is divided into four blocks, each lasting five weeks. During each block, participants undergo one of the recovery interventions.
Interventions:
CWI: Five intermittent immersions of 2 minutes each in cold water (11°C). HWI: Continuous immersion of 18 minutes in hot water (38°C). NI: No immersion. TI: Based on thermographic assessments, participants receive either CWI or HWI. Outcome measures include muscle fatigue, performance metrics, biomarker levels, and subjective recovery assessments.
BASIC_SCIENCE
NONE
Practicality and Feasibility: The interventions (cold and hot water immersions) are easily distinguishable by participants due to their distinct physical sensations, making blinding impractical.
Transparency and Compliance: An open-label design allows full transparency with participants, enhancing compliance and cooperation as they understand the procedures and potential benefits.
Ethical Considerations: Providing complete information respects participants' autonomy and their right to make informed decisions about their participation, especially for physical interventions affecting their health.
Data Collection and Monitoring: The open-label design facilitates easier monitoring and data collection, improving accuracy and reliability without the need for complex blinding procedures.
Focus on Objective Measures: The study relies on objective measures (thermography, biomarker analysis, performance tests)
Study Groups

Cold Water Immersion (CWI)
Participants undergo five intermittent immersions of 2 minutes each in cold water (11°C), with 2-minute rest periods in between.
Cold Water Immersion (CWI)
Participants undergo five intermittent immersions of 2 minutes each in cold water (11°C), with 2-minute rest periods in between.
Hot Water Immersion (HWI)
Participants undergo a continuous immersion of 18 minutes in hot water (38°C).
Hot water immersion (HWI)
Participants undergo a continuous immersion of 18 minutes in hot water (38°C)
No Immersion (NI)
Participants follow the same protocol structure without any immersion.
No interventions assigned to this group
Thermography-Guided Immersion (TI)
Based on thermographic assessments, participants with a hypothermic profile (decreased temperature) receive hot water immersion, while those with a hyperthermic profile (increased temperature) receive cold water immersion.
Thermography-Guided Immersion (TI)
Based on thermographic assessments, participants with a hypothermic profile (decreased temperature) receive hot water immersion, while those with a hyperthermic profile (increased temperature) receive cold water immersion.
