Which of the following is considered a health-related component of fitness?

Flexibility is a crucial health-related component of fitness, as it contributes to overall physical health and well-being. It refers to the range of motion around a joint or group of joints and is essential for performing daily activities, enhancing athletic performance, and preventing injuries. Improved flexibility can lead to better posture, reduced muscle tension, and increased blood circulation, all of which contribute to overall physical fitness and health.

Other components mentioned, such as power, reaction time, and speed, are primarily classified as skill-related aspects of fitness. While they are important for specific athletic performance, they do not have the same direct connection to health outcomes that flexibility does. Health-related fitness components primarily focus on aspects that promote a healthy lifestyle, such as cardiovascular endurance, muscular strength, muscular endurance, body composition, and flexibility.
