Which assessment method is commonly used to measure muscular strength and endurance?

• A. VO2 max test.
• B. BMI measurement.
• C. 1RM or repetitions to fatigue.
• D. Sit-and-reach test.

Answer: (C)

Measuring muscular strength and endurance is best captured by tests that quantify how much force a muscle can produce in a single maximal effort or how many repetitions it can perform before fatigue. A one-repetition maximum (1RM) provides a direct measure of maximal strength—the greatest load you can lift with proper form once. Repetitions to fatigue at a given submaximal load reflect muscular endurance—the ability to perform repeated contractions over time. Together, they give objective, scalable data on both strength and endurance for major muscle groups.

Tests like VO2 max assess cardiovascular endurance, BMI is a body size/weight relative to height measure, and the sit-and-reach test evaluates flexibility, not muscular strength or endurance.
