Which of the following is a listed benefit of iso training?

• A. Blood pressure regulation
• B. Increased sprint speed
• C. Mass gain
• D. Reduced endurance

Answer: (A)

Isometric training, which involves holding a muscle in a static contraction, is often listed for its effect on blood pressure regulation. Regular, safely performed isometric holds can improve vascular function and lower resting blood pressure over time, so this outcome fits best as a listed benefit. The other options come from different training outcomes: sprint speed typically improves with dynamic, explosive work rather than static holds; mass gain relies on muscle hypertrophy from progressive resistance and higher training volumes; and reduced endurance isn’t a recognized benefit—if anything, isometrics can improve muscular endurance in static tasks, but that’s not the primary listed benefit here.
