Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is made up of 11 parts - 6 of them health related and 5 skill related. All of the parts are important to good performance in physical activity, including sports. But the 6 are referred to as contributing to health-related physical fitness because scientists in kinesiology have shown that they can reduce your risk of chronic disease and promote good health and wellness. These parts of fitness are body composition, cardiorespiratory endurance, flexibility, muscular endurance, power, and strength. They also help you function effectively in daily activities. As the name implies, skill-related physical fitness components help you perform well in sports and other activities that require motor skills. For example, speed helps you in sports such as track and field. These 5 parts of physical fitness are also linked to health but less so than the health-related components. For example, among older adults, balance, agility, and coordination are very important for preventing falls a major health concern, and reaction time relates to risk for automobile accidents.
