The two health related components of fitness are muscular strength and muscular endurance
Muscular strength and muscular endurance are indeed two important health-related components of fitness, but they are not the only ones. The five primary health-related components of fitness are:
1. Cardiovascular endurance: Also known as cardiorespiratory endurance or aerobic fitness, this component refers to the ability of your heart and lungs to supply oxygen to your body during sustained physical activity. Activities that help improve this aspect of fitness include running, swimming, cycling, and other aerobic exercises.
2. Muscular strength: This refers to the amount of force your muscles can produce. It is usually measured by the maximum weight you can lift or the maximum resistance you can overcome in a single effort. Activities that improve muscular strength include weightlifting and resistance training exercises.
3. Muscular endurance: This is the ability of your muscles to exert force repeatedly or to sustain a contraction for an extended period. This could relate to doing numerous repetitions of an exercise, like push-ups or sit-ups, or holding a plank for as long as possible.
4. Flexibility: Flexibility is the range of motion around a joint or a group of joints. It's important for general movement and can help prevent injuries during exercise. Stretching exercises and yoga are typical ways to improve flexibility.
5. Body composition: This refers to the make-up of your body in terms of fat mass and lean mass (including muscles, bones, water, etc.). A healthy body composition has a lower proportion of body fat and a higher proportion of lean mass. Body composition can be improved through diet and exercise that targets fat loss and muscle building.
These components are interconnected and contribute to overall health and physical fitness. A balanced approach to training that incorporates activities targeting all these areas can help an individual achieve a high level of physical fitness and well-being.
