Step 1: Question Interpretation
The question requires calculating the percentage reduction in explosive power over a one-month interval. Common causes for such a decline include physical exhaustion, injury, inadequate recovery, or excessive training.
Step 2: Option Evaluation
- (A) 30%: This option represents a plausible figure for explosive power reduction over one month, aligning with findings on fatigue, overtraining, or diminished intensity. This is the correct selection.
- (B) 18%: A decrease of this magnitude is less probable, as substantial losses in explosive power due to overtraining and insufficient recovery are typically greater.
- (C) 15%: While a 15% reduction is conceivable, it is not the usual extent of explosive power loss over a month unless the decline is gradual.
- (D) 32%: This represents an exceptionally large decrease, which is uncommon unless an athlete sustains a severe injury or experiences extreme physical hardship.
Step 3: Conclusion
Therefore, the accurate response is Option (A): 30%.
