Question 14

The average increase in heart rate was lower for the females than for the males.

This statement accurately reflects the data, indicating that female athletes experienced a smaller increase in heart rate compared to their male counterparts after 30 minutes of exercise.

A) The male athletes used more energy than the female athletes after 30 minutes of exercise.

This option is incorrect as it makes a comparative statement about energy usage that is not supported by the provided data. The question focuses specifically on heart rate changes rather than energy expenditure.

B) Strenuous exercise is more difficult for male athletes than female athletes.

This statement is not valid as it generalizes the difficulty of exercise based on gender without any data to support such a conclusion. The focus of the data is on heart rate responses, not on subjective experiences of difficulty.

C) The average increase in heart rate was lower for the females than for the males.

This option is correct as it directly summarizes the data regarding heart rate changes after exercise, providing a clear and valid conclusion based on the measurements taken.

D) All the females had a lower heart rate than the males after 30 minutes of exercise.

This option is incorrect because it makes an absolute statement that may not be true for every individual. The data indicates averages, not guarantees for all individuals in each group.

Conclusion

The correct answer, C, accurately summarizes the data regarding the heart rate increases of female and male athletes, highlighting a significant difference in their physiological responses to exercise. All other options either misinterpret the data or make unsupported claims, reinforcing that C is the only valid conclusion.
