What is the impact of strength training on metabolism?

• A. It has no significant impact
• B. It can increase resting metabolic rate
• C. It decreases overall calorie expenditure
• D. It reduces muscle mass over time

Answer: (B)

Strength training positively impacts metabolism primarily by increasing the resting metabolic rate (RMR). This occurs because muscle tissue is metabolically active, meaning it requires more energy to maintain than fat tissue. When you engage in strength training, you build muscle mass, which in turn raises your RMR. This means that even when you are at rest, your body burns more calories compared to when you have less muscle mass. Furthermore, the process of strength training leads to an afterburn effect, known scientifically as excess post-exercise oxygen consumption (EPOC), where the body continues to expend energy at an elevated rate after the workout is completed. This contributes to additional calorie expenditure, further benefiting overall metabolism. In contrast, the other options are not accurate in capturing the effects of strength training on metabolism. Options that suggest no significant impact omit the well-documented enhancement of RMR through muscle gain. Similarly, stating that strength training decreases overall calorie expenditure or reduces muscle mass over time fails to acknowledge the evidence that strength training leads to increased muscle and higher energy expenditure, ultimately promoting a more active metabolism.
