Question 1

Question

A 42-year-old firefighter candidate undergoes VO2 max testing showing 32 mL/kg/min (below required 42 mL/kg/min). His body composition shows 28% body fat. He has normal cardiac function (ejection fraction 60%), hemoglobin 15.2 g/dL, and no respiratory disease. Lactate threshold occurs at 65% of VO2 max. Evaluate the most effective evidence-based training strategy to meet occupational requirements within 12 weeks.

Accepted Answer

Combined approach: HIIT twice weekly plus threshold training three times weekly

Answer

Threshold training at lactate threshold intensity for extended durations

Answer

Resistance training focusing on muscular strength to improve work efficiency

Answer

High-intensity interval training (HIIT) at 90-95% VO2 max with active recovery

Answer

Continuous moderate-intensity training at 60-70% VO2 max for 60 minutes daily
