Which of the following statements is true about resistance in a fitness context?

In a fitness context, resistance refers to the opposing forces that individuals encounter during exercise, particularly when engaging in activities like weight lifting, bodyweight exercises, or resistance bands. This concept is foundational in strength training; when a muscle encounters resistance, it works to overcome that force, leading to improvements in muscular strength and endurance over time. By training against resistance, individuals can effectively stimulate muscle growth, enhance overall physical performance, and achieve specific fitness goals.

The other statements do not accurately reflect the role of resistance in fitness. It does not always lead to fatigue, as fatigue can depend on various factors including intensity and duration of the activity. Resistance training is beneficial for everyone, not just competitive athletes; it can help improve strength and health for individuals at all fitness levels. Lastly, resistance is indeed deeply related to overall fitness, as it contributes significantly to muscular strength, which is a key component of physical fitness.
