Final answer:
The student's questions pertain to defining various components of physical fitness: Cardiovascular fitness is about heart and lung capacity for prolonged oxygen delivery, flexibility relates to movement range at a joint, body composition details the fat to lean mass ratio, muscular endurance is about muscle stamina without fatigue, and muscular strength deals with the maximal force a muscle can exert.
Step-by-step explanation:
- Physical fitness is a multifaceted concept comprising various components, each vital for overall health and performance. Here are the corresponding fitness components for each definition provided by the student:
- Cardiovascular fitness - It is the capacity of the heart and the lungs to sustain oxygen to muscles for a prolonged period of time.
- Flexibility - It is the ability to move a body part through a full range of motion at a joint.
- Body composition - It refers to the ratio of body fat to lean body mass.
- Muscular endurance - It refers to the ability of the muscle to work over a prolonged period of time without fatigue.
- Muscular strength - Refers to the maximum amount of force a muscle can exert against an opposing force.
Aerobic exercises, such as cycling, walking, and running, increase muscular endurance and cardiovascular health. Meanwhile, anaerobic exercises, like weight training or sprinting, enhance muscular strength. To improve flexibility, exercises such as stretching should be performed, which also help in reducing the risk of injuries associated with physical activities. Finally, knowing the body composition is crucial for assessing the proportion of body fat in comparison to lean mass, which includes muscle, bone, and water.
