Final answer:
The statement that fit people can meet daily physical challenges with energy to spare is true. Fitness enhances cardiovascular and muscular capabilities, leading to more efficient energy use and better health outcomes. Regular physical activity is key to maintaining and improving such fitness levels.
Step-by-step explanation:
The statement 'People who are fit can meet daily physical challenges with energy to spare' is true. Being fit typically means that an individual has the cardiovascular and muscular endurance, strength, and flexibility to handle various physical tasks with greater ease than those who are less fit. Regular exercise and increased physical activity lead to improved health by increasing cardiovascular and muscular fitness, which enables the body to function more efficiently. This, in turn, results in having extra energy even after dealing with daily physical challenges.
Studies have shown that increased physical fitness is associated with reduced stress and better health outcomes. Engaging in physical activities such as riding a bicycle—even up a gentle hill—will increase potential energy as well as improve fitness. Although it might be tiring, it contributes to long-term energy and fitness gains.
