The 2000 Meter Race - 2nd hour by Eva Cone

g1q1.) adrenaline, stress, concentration, anticipation

2018-08-29 14:59:27 UTC

g1q2.) all blood flows away from digestive and urinary systems goes to muscles (adrenaline causes this)
g1q3.) glucose levels drop, sweating causes loss of electrolytes
g1q4.) due to sweat lack of water within the last hour and sunlight, dehydration was setting in

g6

2018-08-29 14:59:47 UTC

1.) stress and adrenaline
2.) the systems decrease in efficiency
3.) They go down because his digestive system is not working as well as before and carbohydrates are not being as quickly converted into glucose.
4.)He is dehydrated

g3

2018-08-29 15:00:01 UTC

1) adrenaline and stressed from anticipation
2) all of the blood flow is going to the muscles instead of the digestive system and the urinary system.
3) his blood glucose level increased
4) water left his mouth to go to other parts of his body to keep his systems working properly

Group 2

2018-08-29 15:00:17 UTC

1) Jim is stressed, nervous, and anxious causing sweat and an increase in heart rate.
2) The digestive and urinary systems would begin to slow down to concentrate on his stress and anxiety.
3) The blood glucose levels would be decreasing as the digestive system is slowing down and bring blood away from the system in order to bring it to heart which is pumping faster and needs the increase in blood circulation.
4) Jim's mouth is dry as the digestive system is slowing down and not producing saliva as fast as usual.

Group #4 :)

jkjaworski — 2018-08-29 15:00:36 UTC

1. The adrenaline that was provoked from the anticipation of the race. This is the nervous system working to maintain homeostasis.
2. There is a decrease in blood flow in the urinary and digestive system since the blood is being distributed more frequently to the muscular system since that is where more blood will be needed.
3. His blood glucose levels were raised due to the stress he felt in acceptation of the race.
4. The water is needed throughout the body to keep it functioning properly. Also, dry mouth can be a sign of stress throughout the body.

Group 5:

2018-08-29 15:01:15 UTC

1. him being nervous & stressed
2. Blood flow is redirected from digestive system to the muscles
3. decreasing
4. to conserve water

g1q5.) heart rate increasing, muscles contracting and expanding at a very high rate, uses sweat as a cooling system to lower his rising body temp

2018-08-29 15:03:43 UTC

g1q6.) increased acidity, increased temperature
g1q7.) extreme use of energy, lack of atp in the muscles, release of lactic acid cause the burning feeling
g1q8.) before the race he hydrated, now the sweat keeping his body cool but the water is also needed to remove nitrogenous wastes from his blood

g6

2018-08-29 15:03:52 UTC

5.) Since he exerting force, his cells are using oxygen more quickly and his heart must work harder to pump blood throughout his body to deliver more oxygen
6.)He needs more energy, oxygen is released to promote the production of ATP which will give him more energy to keep working.
7.) The harder Jim works, the higher the buildup of lactic acid in his muscles.
8.) Water is needed to both cool him down and to remove nitrogenous waste from his blood. both of these processes require the water in his system, so he drank more before the race so that his body would have enough.

group 5

2018-08-29 15:05:26 UTC

5. exerting force, oxygen is used more quickly
6. muscles need more more oxygen
7. Starting to use lactic acid, instead of oxygen
8. urinary system is supressing, so water is used in the form of sweat instead of removing wastes. He drank more water

g3

5) his muscles need to contract to expand more often because he needs more oxygen distributed to his muscles as a result of breathing heavily. His body temperature is increasing so his body is sweating to maintain homeostasis.
6) the large amount of CO2 increases the acidity of blood which promotes the unloading of oxygen so it can balance out.
7) the build up of lactic acid is taking place which gives off a burning sensation. Every time he stresses his muscles, it tears very little.
8) heat is produced when working the muscles and he sweats to maintain your his temperature but also needs the water to stay hydrated. He drank a lot of water.

g6

9.) a- The body has to exert less force to maintain a level of activity than it would if he were increasing that activity
b- to preserve his energy
10.) heart rate lowers slightly, breathing gets slower, body temperature goes up

g1q9.) decreased his number of strokes from 39 to 34 in order to give his body a slight break in preparation for the sprint

2018-08-29 15:09:51 UTC

g1q10.) body temp rises, heart rate lowers, respiratory rate lowers

group 5

2018-08-29 15:10:09 UTC

9. He is exerting less force, he did this in order to not exert too much energy
10. breath rate & heart rate went down, temp increased

Group 2

2018-08-29 15:10:48 UTC

5) Jim's muscles have to contract quicker, increasing the heart rate to allow for the blood to circulate quicker and get to the muscles. He is also sweating as his body temperature increases.
6) Jim's muscles are having to contract at a much quicker rate, compared to when he was sitting still.
7) They are producing lactic acid.
8) Jim has to sweat to out the nitrogenous waste to cool down his both temperature, but also has to take in water in order to not become dehydrated.

g6

2018-08-29 15:11:59 UTC

11.)His body is still laughing enough oxygen to power his cells. Breathing more and the faster pumping of blood allows this oxygen to be replaced more quickly.
12.) Since his body requires less water now, he is using a lot more of the water in his system as sweat to lower his body temperature.
13.) Glucose levels have lowered, pH has lowered due to lactic acid, creatinine levels increase slightly, lactate levels increase, body temperature has increased.

group 5

2018-08-29 15:12:19 UTC

11. His body had to make up for the oxygen exerted during the race
12. he is sweating more to cool his body down and maintain homeostasis
13. temperature increased, glucose levels have gone down, more acidic due to lactate levels going up

g1q11.) his cells are still oxgyen deprived therefore the heart needs to work and he needs to take in oxygen

2018-08-29 15:12:49 UTC

g1q12.) heat is a byproduct of a chemical reaction in the body, therefore he still needs to make up for what he lost during the race
g1q13.) glucose lower, pH unbalanced, lactate increased, creatine increased, temperature increased

Group #4

jkjaworski — 2018-08-29 15:13:46 UTC

5. The new demands are the intense physical labor of rowing at 34 strokes per minute. His muscles are required to contract faster than normal. The body increased the temperature to 99.5 and he was intensely sweating as his heart rate was 201 bpm.
6. His muscles are required to contract faster than normal.
7. The muscles are built up with lactic acid with the increase of blood flow causing a burning sensation.
8. He is well hydrated as the body is sweating to release toxins during the race.

group 5

2018-08-29 15:15:37 UTC

14. needs less oxygen in his blood, and has stopped eerting energy

15. water weight, burned energy and nutrients
16. it would throw his system off

g6

2018-08-29 15:15:44 UTC

14). His body isn't moving as much so he requires less oxygen, he also takes small sips of water
15.) He lost a lot of water weight through sweat
16.) It can cause the salt levels in your blood to drop too low, the blood becomes slightly diluted

g3

2018-08-29 15:16:06 UTC

9a) he reduced the intensity of each stroke
9b) he did this to reserve some of the power for his last push
10) his heart rate dropped very little and his body temperature rose very little

g1q14.) stopped strenious activity, taking deep breaths, starting to rehydrate,

2018-08-29 15:17:52 UTC

g1q15.) burning calories, loss of water weight due to sweat
g1q16.) quench his thirst, large sips would have overloaded his still recovering body

Group 2

2018-08-29 15:19:25 UTC

9) Jim has begun to row slower as he knew his body would not be bale to keep up the high demands of rowing so quickly as he was.
10) His heart rate began to decrease along with his respetory rate decreasing.

g3

2018-08-29 15:20:48 UTC

11) he needs to allow time for homeostasis to take place so his whole body can readjust
12) there is not as much tension to his muscles so his body can focus on other parts rather than just his muscles
13) when his glucose levels go down because he uses glucose to produce energy. pH should have remained the same. Lactate levels went up because he was working his muscles. Creatinine levels should be up because of the way he was using his muscles. Temperature goes up because he lost a lot of water and his body was using a lot more energy.

Group 4

jkjaworski — 2018-08-29 15:20:56 UTC

9. He put himself into a trance shutting out the pain and external distraction to focus on the race. He is doing this to save energy for the final end of the race.
10. His heart decreased and his body temperature also decreased. His respiratory rate was also decreased slightly.

Group 2

2018-08-29 15:21:16 UTC

11) Jim's body is trying to accommodate for the increase of oxygen and liquids that is required during the race.
12) His body is trying to get back to its normal state and the systems can focus on themselves, not just on rowing.
13) Glucose levels: decrease
pH: increase
lactic levels: increase
creatinine levels: increase
temperature: increase

Group 4

jkjaworski — 2018-08-29 15:22:45 UTC

11. The body is trying to compensate for the extreme intensity of the race.
12. He is trying to fully cool his body temperature to maintain that homeostasis.
13. His glucose levels are decreasing drastically because he expedited a significant amount of force through his muscles.

Group 4

jkjaworski — 2018-08-29 15:23:57 UTC

14. He has decreased his amount of physical exertion. He sweated more to bring his body temperature down.
15. He used up his water weight which made him loose weight.
16.

g3

2018-08-29 15:25:01 UTC

14) he drank water periodically and had a cool down until his body went back to normal
15) he lost water weight from sweating
16) Too much water intake causes the body to not handle it. Drinking water slowly gives your body time to adjust to the water. The water to salt levels become unbalanced if water intake is too much.

g3

2018-08-29 15:25:07 UTC

Group 2

2018-08-29 15:25:23 UTC

14) He is now relaxed and barley moving.
15) He lost 4 pounds by sweating out so much liquid during the race.
16) He only took sips as his urinary and digestive systems were just beginning to work at their normal rate again, so he was accommodating for his systems by not over capacitating them.
