Final answer:
The correct answer is c) Increased risk of chronic diseases. Cardiorespiratory fitness provides benefits such as improved heart health and enhanced lung capacity, but does not increase the risk of chronic diseases.
Step-by-step explanation:
The question is asking which option is not a benefit of cardiorespiratory fitness. Cardiorespiratory fitness is known to provide several health benefits such as improved heart health, enhanced lung capacity, and efficient oxygen utilization. However, it does not increase the risk of chronic diseases; in fact, it lowers the risk. Therefore, the correct answer to the question is c) Increased risk of chronic diseases.
Aerobic exercises, which are part of cardiorespiratory fitness, improve cardiovascular and muscular fitness, increase bone density and strength, and enhance cognitive function. These exercises help the heart pump blood more efficiently, and the body to use oxygen more effectively. Regular physical activity has also been linked to reductions in hypertension, bad cholesterol, high total cholesterol, and excess body weight, while increasing good cholesterol and insulin sensitivity. It's clear that increased risk of chronic diseases is not an outcome of improved cardiorespiratory fitness.
