Answer:
B. John should complete several weight-lifting routines over time.
Explanation:
If John wants to participate in a competition that will assess the size and definition of his muscle, he must start preparing in advance, establishing a weight training schedule where he must complete several weight lifting routines over time. In this way, John's muscle will become defined and large without damaging his body and allowing him to participate in the competition efficiently.

b) Touch the door handle to feel if it’s hot
c) Feel the closed door with the back of the hand, from the bottom up
d) Have a fire extinguisher ready before opening the door
Answer:
c) Feel the closed door with the back of the hand, from the bottom up
Explanation:
The Community Emergency Response Team is a team that is in charge of helping the community in case of emergencies and know how to act in case of all the casualties that can occur, when a member or a CERT is searching for survivors in a building after an electrical storm, he should check and feel the closed door with the back of his hand from the bottom up to see if it is hot, or if there is fire inside.
The heart is the system’s pump and the blood vessels are like the delivery routes and it is a muscle. The pumps are the beat.
The heart is a muscle about the size of a fist and it is the muscle in the body that works the hardest.
The statement that the heart muscle rests only between beats is true.
B for 200W, A for lactate threshold, C for 250W lactate, B for lowest VO2max, A for energy increase 150W to 200W, C for highest VO2max.
Subject B expends the most kcal/min cycling at 200W, as their VO2 value (2600 ml/min) is the highest among the three subjects at this intensity. This indicates a higher energy expenditure. The VO2 values reflect the oxygen consumption during exercise and provide insights into energy utilization.
Subject A's higher blood lactate threshold is evident from their higher VO2 values at all exercise intensities. This suggests their ability to tolerate higher exercise intensities before lactate accumulation.
Subject C's highest blood lactate concentration at 250W signifies the onset of anaerobic metabolism, where lactate production surpasses its removal. This points to differences in aerobic capacity among the subjects.
Subject B's lowest VO2max (3800 ml/min) implies their comparatively lower maximal aerobic capacity. VO2max represents the maximum amount of oxygen an individual can use during intense exercise and is a key indicator of fitness.
Subject A's largest increase in energy expenditure from 150W to 200W indicates higher efficiency in utilizing energy sources during exercise progression.
Subject C's highest VO2max (3000 ml/min) showcases their superior aerobic fitness compared to the other subjects, emphasizing their maximal oxygen uptake capacity.

ANSWERS:
1. Which subject expends the most kcal/min cycling at 200W?
- A: 2800
- B: 2600
- C: 2500
The answer is A
2. Which subject has the highest blood lactate threshold?
This would be the subject who can maintain a higher VO2 at higher wattages without a significant drop.
- A's VO2 drops by 200 from 250W to 300W.
- B's VO2 doesn't drop from 250W to 300W.
- C's VO2 drops by 500 from 250W to 300W.
The answer is B.
3. Which subject has the highest blood lactate concentration at 250W?
This would be inferred from a significant drop in VO2 at the next higher wattage (300W).
- C has the most significant drop, so the answer is C.
4. Which subject has the lowest VO2max?
- A's highest VO2: 3900
- B's highest VO2: 3800
- C's highest VO2: 3500
The answer is C.
5. Which subject has the largest increase in energy expenditure going from 150W to 200W?
- A: 600 increase
- B: 700 increase
- C: 500 increase
The answer is B.
6. Which subject has the highest VO2max?
As mentioned in the answer to question 4, the answer is A with a VO2max of 3900.
