Which short statement correctly differentiates musculoskeletal strength from musculoskeletal endurance?

• A. Strength is the ability to sustain repeated submaximal contractions for long durations, whereas endurance is defined as the single maximal lift capacity measured via 1RM testing.
• B. Strength measures primarily flexibility and joint range of motion, whereas endurance exclusively measures VO2 max and cardiorespiratory adaptation.
• C. Strength refers to the maximal force a muscle or muscle group can produce (often measured by 1RM), whereas endurance refers to the ability to sustain submaximal force repeatedly over time (measured by repetition maximum at lower loads).
• D. Strength and endurance are identical concepts and are always measured using the same test protocols and loads, without differentiation between reps or load.
