Answer 1

PART A

First calculate the Maximum Heart Rate by subtracting the candidate age from 220.

220 – 60 = 160.

Given, range of 70 to 80% for aerobic training, calculate training heart rate

70% of 160 = 112

80% of 160 = 128

Hence, the answer is 112, 128.

PART B

First calculate the Maximum Heart Rate by subtracting the candidate age from 220.

220 – 27 = 193.

Given, range of 75 to 85% for aerobic training, calculate training heart rate

75% of 193 = 145

85% of 193 = 164

Observed heart rate is 30 beats in 15 seconds i.e. 120 beats per minute.

As the observed heart rate is lower than the required heart rate, John needs to run faster to increase heart rate.

Hence, the answer is b) No, he needs to run faster to increase his heart rate.

PART A

The high fat meal makes the body absorb more water from the colon and thus the leading to dehydration. Also, low water content in body can lead to slow digestion of fats due to which the required energy is inadequate. Also, dehydration is known to alter a person’s mood, energy level and ability to think clearly. Hence, Greg felt fatigue and cranky.

PART B

Before practice, it is recommended not to have heavy meals. Also, a balance between carbohydrate and protein along with low fat is required to provide sufficient energy during practice.

Hence, the answer is “Greg would need to consume smaller snacks that include both protein and carbohydrate.
