Which short statement correctly differentiates musculoskeletal strength from musculoskeletal endurance?

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.

Strength measures primarily flexibility and joint range of motion, whereas endurance exclusively measures VO2 max and cardiorespiratory adaptation.

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).

Strength and endurance are identical concepts and are always measured using the same test protocols and loads, without differentiation between reps or load.
