2. Mr. P. Nice-Anderson, a 21 year old influencer and vlogger, received a number of unsolicited comments calling him chubby and fat in his new post. Brought about by his insecurities and lack of confidence, he started to become very conscious of his body to the point wherein he desperately reduced his calorie intake to a very low level; from 2000 to 2100 each day to only 700-800 now. This was, for him, the fastest way of resolving the issue thus allowing him to appease the negative outlook he had impressed upon himself. Overall, this method of his lasted for 5 to 6 months. Upon constant observation, however, he seemed to have noticed that there had been only quite few changes within his bodily composition since then. He became frustrated about this matter and started to eat more than his acclimated diet (or regresses back towards his original diet). This, in turn, had resulted in him gaining more body fat. What is the best explanation for this?

3. Which of the following are the two primary energy sources used by the body?

4. Gerald participated in a marathon for a charity. Being a competitive person, he started the race by sprinting as fast as he could. In approximately 20 seconds, what would be his source of ATP?

5. Type of adaptation of the energy systems wherein there is greater substrate storage at rest and altered creatine kinase and myokinase activity

6. All the following are true regarding Excess Post-exercise Oxygen Consumption (EPOC), except:

7. The following are fast-acting hormones EXCEPT:

8. Jodie T., upon revisiting New York after 12 years, notices the big difference in the design of the world trade center before its tragic fate and how it is now. A lover of physiology as she is, she then tries to correlate the deterioration as well as the reconstruction of which with the two general types of metabolic pathways. That is, anabolism and catabolism. Given this, what now can be inferred to as the right analysis for Jodie’s observation:

9. Dwayne, a weightlifter was tasked by his physical trainer to engage in biking, an endurance training, to enhance recovery. After doing this for quite some time, Dwayne's anaerobic capabilities of lifting weights were observed to decrease significantly. What type of metabolic specificity training explains this situation?

10. For an activity in P.E., the PT block was divided into subgroups A and B. Group A was assigned to a high-intensity workout while Group B was in a low-intensity workout. In the duration of their exercise, where more than 2 minutes have passed, what would be their main source of energy? A:_____; B:_____

11. Basal Metabolic Rate represents the total energy expenditure in one day. It consists of three components. The first one is the resting metabolic rate wherein it refers to the energy consumed by the body even at rest so as to keep all its systems functioning correctly (such as breathing, keeping the heart beating to circulate blood, growing and repairing cells and adjusting hormone levels). This accounts for the largest energy expenditure of our body in a single day, having a percentage of about 60-75%. The second one is the thermic effect of physical activity wherein it refers to the energy used by our body for physical movement. This accounts for about 15-30% of our body’s total energy expenditure. The last one is the thermic effect of food wherein it refers to the energy our body uses to digest, absorb and store the nutrients we get from the foods we consume. This accounts for about 10% of our body’s total energy expenditure.

12. The lower the exercise intensity, the shorter the amount of time it can be performed.

13. RJ is seated by a table, reading a book. We can say that much of the energy in his body is being released from fats.

14. Emma has diabetes. Her endocrinologist suggested that she should exercise more. If Emma followed the doctor’s advice, which of the following will be true?

15. Arrange the energy systems from having the fastest energy liberation speed to the slowest.

16. Which hormone is responsible for releasing glycogen from the liver?

17. Hidilyn Diaz was a well-known weightlifter, who won the first Olympic gold medal for the Philippines in the 2020 Olympics. Given the nature of her sport, what would be the relative energy contribution (%) of aerobic and anaerobic means of energy production?

18. Which of the following, when depleted or reduced in amount, will significantly limit exercise performance?

19. Antidiuretic Hormone (ADH) is a hormone that increases water reabsorption into the blood. Thus, this results in a decrease in water excreted from the body. What is the effect of exercise that is longer than 30 minutes on this hormone?

20. This type of training is the brief repeated bouts of high-intensity exercise with intermittent recovery periods to elicit cardiopulmonary, metabolic, and neuromuscular adaptations.
