Cardiovascular endurance can impact body composition, and the most accurate statement is:
It contributes to a lower body fat percentage.
Engaging in regular cardiovascular exercise can help increase calorie expenditure, improve metabolic health, and reduce body fat when combined with proper nutrition. While excessive cardio without adequate strength training could potentially lead to muscle loss, when balanced with resistance training, cardiovascular exercise typically aids in reducing body fat while preserving or even increasing lean muscle mass.
