I hope to contribute to the Exercise Physiology topic page on Wikipedia. I want to add a section on Lactic Acid buildup and its potential positive and negative effects on exercise. Dbaladi10 (talk) 05:00, 23 April 2013 (UTC)

Wikipedia 4

Lactic Acid is a yellow, water-soluble liquid produced during muscle contraction as a byproduct of anaerobic glucose metabolism. When an untrained person reaches 50-60% of his VO2 max, (trained is 65-80%), lactic acid begins to produce. A rise in lactic acid has been shown to come from an increased reliance on the anaerobic metabolism (Powers 2001).

I plan to expand on this topic in more detail. Expand on any of the positives or negatives to lactic acid production. This will involve going through different metabolic pathways and the ways in which different energy sources and fuel sources are used.Dbaladi10 (talk) 00:48, 2 May 2013 (UTC)

Expansion of the Article.

- ATP is a functional unit in that stores and transfers energy to muscle cells. Although Glycolysis leads to an increased lactic acid production, it rapidly provides the muscle with ATP (Adenosine-triphosphate) (Clark 51-52).

- There are several bionergetic systems within our body to create ATP, the three main ones are the ATP-CP system, Glycolysis and the Krebs Cycle (Clark 52-53) (Powers, 33).

- Different systems are used when different energy is needed for the given exercise. There is anaerobic and anaerobic training. In situations lasting longer than 30 seconds, they require oxygen and are then recognized as aerobic. In exercises that only last for a short duration, oxygen is not necessarily necessary for proper completion of the exercise (Clark 51.

- ATP-CP and glycolysis are the primary pathways in which Lactic acid can be produced. ATP is generally produced during Anaerobic (Without oxygen) exercises. The ATP-System is used before any exercise, no matter the intensity because of its ability to produce ATP more rapidly than the other systems (Clark 52) (Powers 34).Dbaladi10 (talk) 01:24, 2 May 2013 (UTC)

Peer Reviews

The Walt Disney Company by Jmathews63 I really like your potential addition to the The Walt Disney Company page. Being a former customer of both the USA’s Disneyland and the Disneyland in Paris, your comment about how they have to serve wine overseas really fascinated me. The ownership percentages you gave about China also made me think how much power the company actually had overseas, in countries where their cultures and norms may be different than those in Unites States.

Mediation by Bclopez09 After reading your contribution to Mediation I laughed. Not because it was funny but because it is so true. As you said, most conflict occurs from small miscommunication. So often people are misunderstood, misread and it can instantly cause tension and miscommunication. There needs to be a mediator to aid in these miscommunications. You are right in saying that a successful mediator and proper mediation can be a positive contributor to intercultural conflict resolution.Dbaladi10 (talk) 02:26, 2 May 2013 (UTC)

Adding sources and content. (Requested by my Peer reviewers)

New content for Lactic Acid

-Although the muscular fatigue portion of exercise often correlates with high tissue concentrations of lactate, it isn’t necessarily the cause of fatigue. Lactic Acid can potentially be a factor in fatigue during exercise. The increased H+ levels reduces intracellular pH, inhibits glycolytic reactions and directly interferes with muscle excitation-contraction coupling – possibly by inhibiting calcium binding to troponin (Beachle 26).

Hey Danny,

We both share a common interest in this topic and im exciting to see what you write about the effects of lactic acid build up. Just make sure you are using good sources, a lot of information out there is not so great. Also, beware that there are a lot of different opinions on the effects of lactic acid so expect some feedback.

Hey Danny, I like your topic about lactic acid build up, it pertains to a lot of things! Just make sure that the information you are putting on the page is going to be more neutral than one sided! Also, I would state different opinions about the discussion and use a lot of sources. Saifalz (talk) 01:26, 2 May 2013 (UTC)
