Repetitive muscular activity at moderate levels, such as weight training, can result in :

Options

A. denervation atrophy
B. mood swings
C. muscular hypertrophy
D. a decline in health

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the effects of repetitive muscular activity at moderate levels, specifically weight training.

2. **Identifying Possible Outcomes**: The potential outcomes mentioned are:
- Denervation atrophy
- Mood swings
- Muscular hypertrophy
- Decline in health

3. **Analyzing Each Option**:
- **Denervation Atrophy**: This condition occurs when motor nerves that supply muscles are damaged, leading to muscle wasting. This is not a result of moderate weight training.
- **Mood Swings**: While exercise can affect mood, it is not a direct result of moderate weight training.
- **Muscular Hypertrophy**: This is the increase in muscle mass and strength due to consistent and targeted weight training. This is a well-known effect of resistance training.
- **Decline in Health**: Moderate weight training generally promotes health rather than causing a decline.

4. **Conclusion**: The most appropriate answer is muscular hypertrophy, as it is a direct result of repetitive muscular activity at moderate levels, such as weight training.

5. **Final Answer**: Muscular hypertrophy is the result of repetitive muscular activity at moderate levels, such as weight training.
