What term refers to the range of motion possible around a joint?

1. Muscle strength

2. Flexibility

3. Coordination

4. Endurance

The correct answer is: Flexibility

Flexibility refers to the range of motion possible around a joint and is crucial for overall physical performance and injury prevention. It is influenced by various factors, including the elasticity of muscles, tendons, and connective tissues, as well as the structure of the joint itself. Improved flexibility can enhance athletic performance and make daily activities easier, as it allows for greater movement efficiency. Muscle strength is related to the ability of a muscle or group of muscles to exert force, which, while important for overall fitness, does not specifically pertain to the range of motion at a joint. Coordination refers to the ability to use the senses and body parts in a smooth and efficient manner during movement, and endurance is the capacity to sustain physical activity over time. Each of these terms impacts overall fitness and functionality, but flexibility is the specific term that directly correlates to the range of motion around a joint.
