Final answer:
Cardiovascular fitness exercises help reduce fat mass and improve body composition. They contribute to better cardiovascular health by increasing the efficiency of the heart and reducing risk factors for diseases such as hypertension. Aerobic exercises are particularly effective in achieving these benefits.B is the correct answer.
Step-by-step explanation:
Exercises that improve cardiovascular fitness can also positively impact body composition. These exercises are beneficial because they can reduce fat mass.
While several types of physical activities exist, aerobic exercises like cycling, walking, and running are particularly effective at increasing muscular endurance and cardiovascular health. On the other hand, anaerobic exercises such as weightlifting enhance muscle strength but have less of an impact on cardiovascular fitness. It is also important to note that regular exercise can improve bone density, cognitive function, and help with weight maintenance and loss by reducing disease risks.
Regular exercise has the added benefit of releasing myokines from contracting muscles, which are hormones that help with tissue repair and growth, and have anti-inflammatory properties. Overall, cardiovascular health is significantly improved through exercise, which also lowers risk factors for diseases like hypertension and helps manage body weight, elevating the mechanical efficiency of the heart and improving one's quality of life.
