What is muscular strength?

What is muscular strength?

• A. Ability to take in, transport and utilise oxygen
• B. Maximal amount of force a muscle generates
• C. Ability of muscles to contract repeatedly for extended periods of time without fatigue
• D. Range of movement around a joint

Answer: (B)

Muscular strength is the maximal amount of force a muscle or muscle group can generate in a single effort. This is typically shown by how much weight you can lift in one lift, like your one-repetition maximum. It’s about peak force in one contraction, not how long you can work, how efficiently your body uses oxygen, or how far a joint can move. The other descriptions refer to different fitness components: muscular endurance is the ability to perform repeated contractions over time; aerobic capacity is about taking in and using oxygen during sustained activity; and flexibility (range of movement) describes how far a joint can move.
