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

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

Threshold training at lactate threshold intensity for extended durations

Answer

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