When does full contact begin during the heat-acclimatization period?

• A. Day 5
• B. Day 7
• C. Day 6
• D. Day 8

Answer: (C)

Heat acclimatization is a phased process that gradually increases exposure and load so the body can adapt to heat stress. In the early days, training is limited and often wears less protective gear to keep heat burden manageable while the body begins to adapt. Over this period the body makes key physiological changes—plasma volume expands, sweating becomes more efficient, and core temperature is better regulated at a given effort—so athletes can tolerate heat more comfortably. Typically, these adaptations are sufficiently established by the sixth day of the acclimation period to allow full-contact practice. Starting full contact on day six aligns with giving the body enough time to adapt before the added demands of contact, while still keeping overall risk low with proper hydration, monitoring, and environmental considerations.
