Search on the internet the following "exercise and blood buffers". Use the articles you find to address ONE of the following questions in order from 1 to 6 please. Identify which question you are answering by number.
1. We are paying attention to the concept of anaerobic exercise, define this term and give an example of when this type of exercise occurs.
2. What is the body's immediate reaction to intense (anaerobic) exercise?
3. What blood buffers are impacted during intense exercise?
4. How do some athletes counteract the effect of intense exercise on blood buffers?
5. Explain (using Le Chatelier's Principle) the reason "nutritional" supplements counteract the effect of intense exercise.
6. What are some of the side effects to the "nutritional" supplements used?
If we address all of these questions, I will add a topic so that we can continue the thread.
Looks like we have addressed these questions. Let's now look at the following site: http://scifun.chem.wisc.edu/chemweek/biobuff/biobuffers.html Discuss ONE of the concepts from this information.
1) Anaerobic exercise is a short lasting exercise activity that your bodies demand for oxygen exceeds what it can take it causing the creation of lactic acid to form on the muscles while the bodies cells are using fermentation for cellular respiration. An example of this are weight lifting, sprinting, and jumping. Our body has buffers to prevent the addition of this acid to over lower the pH of the body which stays around 7.4.
ReplyDelete1) Anaerobic exercise is any type of exercise that takes a short amount of time to complete, and is powered by metabolic pathways in the body that do not use oxygen, such as energy sources stored in muscles.
ReplyDeleteAn example of when this type of exercise occurs is when people lift weights or sprint.
2) If the exercise is intense there is not enough Oxygen available as an electron acceptor at the end of the Eectron Transport Chain. The body can't produce enough ATP, so the body goes into producing Lactic acid.
ReplyDeleteAthletes use nutritional supplements to elevate the body’s natural buffering capacity. The two most common supplements are sodium bicarbonate and beta-alanine. The downside of sodium bicarbonate is when the bicarbonate reacts with water producing carbon dioxide, and can cause athletes to have extreme stomach cramps and bloating. Taking beta-alanine in large doses can cause blood pressure to rise which may cause flushing and pins and needles. However, taking the beta-alanine in small doses has minimal to no effects.
ReplyDeleteSorry I forgot to state the question number, I addressed number 6.
ReplyDelete4) As reported by Dr. Lee Mancini, sodium bicarbonate becomes an important buffer in the blood for athletes to reduce the acidity that develops with intensity and duration in an athlete. Eventually, this buffer is overwhelmed and can no longer aid in lowering the acidity and results in exercise-induced fatigue. To counteract this effect, the idea of simply using baking soda has been introduced and tested in athletes. Numerous studies provide that ingesting certain amount of baking soda does in fact improve performance. This works in theory, by assisting the sodium bicarbonate to maintain the desired equilibrium in your body. Many athletes also have undesirable side effects that should definitely be taken into account and used cautiously when used as a means of counteracting the rising acidity in athlete's blood to improve performance.
ReplyDelete6) amino acid is an important to athletes as it build the muscles. However, there are some side affects are fatigue and loss of cordination. It should be used only if an someone is doing exercise to best build the muscle.
ReplyDelete3. During intense exercise, pH can drop due to increase H+ presence because of lactic acid build up. If the pH isn't quickly corrected by buffers in the blood, acidosis occurs. This process can negatively affect the carbonic acid/bicarbonate buffer in blood. Sometimes the buffer isn't enough to keep pH at 7.4, so the lungs remove excess CO2 to raise pH and the kidneys remove excess HCO3- to lower pH.

ReplyDeleteanaerobic exercise occurs when the oxidative energy system is not the major workhorse. Our body has 3 main energy systems, the atp/cpr, anaerobic, and oxidative or aerobic. when our body is exercising anaerbobically, we are not relying on on oxygen. An example of this would be weight lifting.
