Section: Coach Cold — Cold as System
This section covers Chapter 3, Lessons 3.1 through 3.3.
Part A — Vocabulary (20 points, 2 points each)
Select the best answer for each question.
1. Cold-Water Immersion for Recovery (CWI) refers to:
A) Swimming for fun B) Cold immersion after training; has clear short-term recovery benefits and some adaptation-blunting in specific contexts C) Hypothermia treatment D) Cold-water rescue
2. Delayed-Onset Muscle Soreness (DOMS) is:
A) Soreness during exercise B) Muscle soreness peaking 24-72 hours after training; reflects damage and inflammation that drives adaptation C) An injury D) Identical to fatigue
3. Exercise-Induced Inflammation refers to:
A) An injury B) The acute inflammatory response to training; important — signals the body to repair and adapt C) Chronic inflammation D) A disease state
4. Distal-Proximal Skin Temperature Gradient describes:
A) Body temperature regulation B) The difference between extremity and torso skin temperature; increases at sleep onset as warm blood reaches hands and feet C) Cold injury severity D) Sweat rate
5. Stress inoculation refers to:
A) Vaccination B) Deliberate controlled exposure to acute stress that builds capacity to handle future stress; cold is a clear example C) Avoiding stress D) A medication
6. Cold as supportive practice (vs. cold as treatment) means:
A) Cold replaces medical care B) Cold is one tool among many that may support mood and stress; it is not a treatment substitute for clinical conditions C) Cold has no effects D) Cold is only recreational
7. Window of Tolerance in the cold context:
A) Tolerance for temperature B) The zone in which a person can experience emotion without becoming overwhelmed; cold practice may widen it C) Time spent in cold D) Pain tolerance
8. Periodization (Cold) refers to:
A) Cold seasons B) Strategic use of cold at different points in the training cycle for sport vs. adaptation goals C) Cold therapy schedules D) Menstrual cycle interaction
9. Pre-sleep cold exposure (in this chapter) typically refers to:
A) Cold plunges before bed B) Brief peripheral cold in the wind-down hour, different from full immersion C) Sleeping in cold rooms D) Cold showers in the morning
10. Acute mood lift from cold:
A) Lasts months B) Short-term mood improvement after a single cold session, lasting hours C) Has no measurable mechanism D) Is the same as treatment for depression
Part B — Concept Comprehension (20 points, 2 points each)
Select the best answer for each question.
11. Research on cold-water immersion immediately after every resistance-training session suggests:
A) Always optimal for adaptation B) Clear short-term recovery benefits but possible blunting of long-term adaptations C) No measurable effect D) Harm to acute recovery
12. The most research-aligned use of cold for a peak competition period is:
A) Avoid all cold B) Use cold-water immersion for short-term recovery — when next-day performance matters more than long-term adaptation C) Cold immersion 5 times daily D) Cold immersion months in advance only
13. Core body temperature at sleep onset:
A) Rises by 2-3°F B) Stays constant C) Drops by approximately 1-2°F D) Fluctuates randomly
14. Bedroom temperature research supports a range of approximately:
A) 50-55°F B) 60-67°F C) 70-75°F D) 78-82°F
15. Morning cold exposure on the same-day sleep typically:
A) Disrupts that night's sleep severely B) Supports daytime alertness without interfering with evening cooling; often supports normal sleep that night C) Has no effect on sleep timing D) Causes insomnia
16. Norepinephrine during cold exposure typically increases by approximately:
A) 5-10% B) 50% C) 200-500% D) Decreases
17. Stress inoculation refers to:
A) Vaccination against stress B) Deliberate controlled exposure to acute stress that builds future stress capacity C) Avoiding all stress D) Medication for stress
18. The most accurate framing of cold practice's relationship to mental health is:
A) Cold cures depression B) Cold is a supportive practice alongside other tools, not a substitute for professional support when conditions warrant C) Cold has no measurable mental health effects D) Cold is only useful for athletes
19. A brief cold-water splash on the face in the wind-down hour:
A) Always disrupts sleep B) Is typically tolerated well as a small parasympathetic-supporting input C) Causes hypothermia D) Has the same effect as a full cold plunge
20. The chapter's overall framing of cold-system interactions is:
A) Cold improves all systems equally B) Timing and context substantially shape whether cold supports or interferes with other goals C) Cold should be avoided entirely D) Cold has no effect on other systems
Part C — Application (30 points, 6 points each)
Write 2-4 complete sentences for each question. Show your reasoning.
21. A high-school athlete is in a 6-week strength training block aimed at building muscle for the upcoming season. Apply what you learned about CWI and adaptation to advise them about whether and when to use cold-water immersion.
22. Explain why morning cold exposure typically does not disrupt that night's sleep, while late-evening intense cold sometimes does. Use the concepts of core body temperature and circadian rhythm.
23. Describe stress inoculation and explain why cold practice is a particularly clear example of it. What skills built through cold practice may transfer to other parts of life?
24. A friend says cold plunges "cured my depression." Apply what you learned about cold and mental health to respond carefully — affirming what may be true while clarifying what the research actually supports.
25. Distinguish "cold as supportive practice" from "cold as treatment." Why does this distinction matter for both individual practitioners and for how cold is presented in popular culture?
