NCSF Body Composition Practice Test

A reduction in body fat combined with an increase in muscle mass typically leads to improved overall health and fitness. When body fat percentage decreases while muscle mass increases, various positive physiological changes occur. This transformation can enhance metabolic function, boost cardiovascular health, and improve insulin sensitivity, all of which contribute to better energy utilization and overall fitness levels.

Increased muscle mass also contributes to a higher resting metabolic rate, allowing the body to burn more calories even at rest. This can help in maintaining a healthy weight and preventing obesity-related diseases. Furthermore, individuals often report enhanced strength, endurance, and physical appearance, which can positively impact mental well-being and motivation to engage in physical activities.

The other alternatives suggest negative outcomes that do not align with the benefits typically associated with a healthy body composition change.
