Accepted Answer

# Brief Explanations:
To determine which statement does not support that strength training (muscular fitness training) reduces injury risk, we analyze each option:
- Option A: Preventing/improving diabetes and sarcopenia relates to health, but not directly to injury risk reduction. However, we need to check others.
- Option B: Increasing muscle mass to enhance metabolism is about metabolism, not injury prevention. Wait, no—wait, let's re - evaluate. Wait, actually, let's look at the focus: injury risk.
- Option C: Strengthening tendons, ligaments, and cartilage directly helps prevent injuries (as these structures support joints and muscles, reducing injury likelihood).
- Option D: Improving self - image and athletic performance. Self - image is a psychological aspect and athletic performance is broader, but neither directly relates to reducing injury risk. Wait, no—wait, the question is which does NOT support why strength training reduces injury risk. Let's re - analyze:
  - A: Diabetes and sarcopenia—sarcopenia is muscle loss with age; preventing it can help with muscle strength, which may reduce injury. But maybe not as direct. Wait, no, let's think again. The key is "why this (reducing injury risk) is true". So we need a statement that is not about injury prevention.
  - B: Increasing muscle mass for metabolism—metabolism is about energy use, not injury.
  - C: Strengthening tendons/ligaments/cartilage—these are structures that when strong, reduce injury (e.g., stronger tendons are less likely to tear).
  - D: Self - image and athletic performance. Self - image is psychological, athletic performance is about how well you perform in sports, not about reducing injury. Wait, but the question is which does NOT support why strength training reduces injury risk. Let's check the options again. The question is "Which statement does NOT support why this (strength training reduces injury risk) is true?". So we need to find the option that is not a reason for injury risk reduction.
  - Option D: Improving self - image and athletic performance. Self - image has nothing to do with injury risk. Athletic performance improvement could be due to better strength, but the self - image part is irrelevant, and the athletic performance part—while better strength can improve performance, the option's focus on self - image and athletic performance (not the injury - preventing aspects of strength) makes it not support the injury risk reduction. Wait, but let's check the other options again.
  - Option B: Increasing muscle mass to increase metabolism. Metabolism is about how the body uses energy. Increasing muscle mass can help with metabolism, but how does that reduce injury risk? It doesn't directly. Wait, now I'm confused. Wait, let's recall: strength training reduces injury risk by strengthening muscles, tendons, ligaments, bones, etc. So:
    - A: Preventing sarcopenia (muscle loss) can help maintain muscle strength, which is related to injury prevention (weaker muscles are more prone to injury).
    - B: Increasing muscle mass to increase metabolism—metabolism is not related to injury risk.
    - C: Strengthening tendons, ligaments, cartilage—these are key structures for joint and muscle support; stronger ones mean less chance of injury (e.g., a stronger tendon is less likely to rupture).
    - D: Improving self - image and athletic performance. Self - image is psychological, and athletic performance is about how well you play, not about not getting injured. So between B and D. Wait, the question is which does NOT support why strength training reduces injury risk. Let's see the original question again: "Strength training is beneficial because it decreases your risk of injury. Which statement does NOT support why this is true?". So we need a statement that is not a reason for the injury - reducing benefit.
    - Option D: Improving self - image and athletic performance. Self - image has no bearing on injury risk. Athletic performance improvement can be from strength, but the option's focus on self - image and athletic performance (not the injury - preventing mechanisms) means it doesn't support the injury - reducing claim. Option B: Increasing muscle mass to increase metabolism—metabolism is about energy, not injury. But maybe I made a mistake. Wait, let's check the options again. The correct answer is D because self - image and athletic performance (the performance aspect, not the injury - preventing strength) do not relate to reducing injury risk. Option C directly relates to strengthening structures that prevent injury. Option A: preventing diabetes and sarcopenia—sarcopenia is muscle loss; preventing it keeps muscles strong, which helps prevent injury. Option B: increasing muscle mass—more muscle mass can support the body better, reducing injury risk? Wait, maybe I was wrong about B. Wait, muscle mass can help with metabolism, but also, more muscle means better support for joints, etc. But the option says "increases muscle mass, which increases your metabolism"—the focus is on metabolism, not on the injury - preventing aspect of muscle mass. So the statement is about metabolism, not about how muscle mass reduces injury. But then between B and D. Wait, the question is which does NOT support why strength training reduces injury risk. Let's think of the core: injury risk reduction is about physical structures (muscles, tendons, ligaments, bones) being stronger to prevent damage.
    - Option C: Strengthens tendons, ligaments, cartilage—directly supports (these structures breaking or being weak causes injuries; strengthening them reduces that).
    - Option A: Prevents or improves diabetes and sarcopenia—sarcopenia is muscle loss; preventing it keeps muscles strong, which helps prevent injury (weaker muscles are more likely to be injured).
    - Option B: Increases muscle mass to increase metabolism—metabolism is about energy, not about injury. But maybe muscle mass also helps with injury, but the statement's focus is on metabolism.
    - Option D: Improves self - image and athletic performance. Self - image is psychological, and athletic performance is about how well you perform, not about not getting injured. So D is about non - injury - related benefits. So the answer is D.
# Answer:
D. Muscular fitness training improves self - image and athletic performance
