Which of the following is NOT considered one of the five health-related components of fitness?

Mental strength is not considered one of the five health-related components of fitness, which are cardiorespiratory endurance, muscle endurance, muscular strength, flexibility, and body composition. The emphasis on health-related fitness components typically focuses on the physical aspects that contribute to overall health. Cardiorespiratory endurance refers to the efficiency of the cardiovascular and respiratory systems during sustained physical activity, muscle endurance relates to the ability of muscles to perform repeated contractions over time without fatigue, and flexibility is the range of motion around a joint.

While mental strength is important for overall well-being and can contribute to performance in physical activities, it does not fit into the traditional framework of health-related fitness components that assess physical capabilities and functions. Mental strength is often associated with psychological resilience and the ability to cope with challenges, which, although valuable, does not directly measure physical fitness in the same way the other components do.
