Lactic Acid...Lactate...Lactose?!

The terms lactic acid and lactate, despite biochemical differences, are often used interchangeably. Fitness professionals have traditionally linked lactic acid or ‘the burn’ with an inability to continue an intensive exercise bout at a given intensity. Although the conditions within the exerciser’s muscle cells have shifted towards acidosis, lactate production itself does not directly create the discomfort (acidosis) experienced at higher intensities of exercise. It is the proton (H+) accumulation, coinciding with, but not caused by lactate production, that results in acidosis, impairing muscle contraction, and ultimately leading to the ‘burn’ and associated weariness (Robergs, Ghiasvand, Parker 2004). The increased proton accumulation occurs most notably from the splitting of ATP (the body’s energy liberating molecule) by the muscle protein filaments, in order to sustain vigorous muscle contraction. Interestingly, the lactate production is proposed to be a physiological event to ‘neutralize’ or ‘retard’ the exerciser’s muscle acidic environment (Robergs, Ghiasvand, Parker 2004). Thus, lactate accumulation, which for years has been associated with the cause of the burn, is actually a beneficial metabolic event aimed at diminishing the burn. Scientists denote conditioning at this physiological state as lactate threshold training.

This stuff is awesome!!!

Here is the article put another way:

"I felt like puking the whole workout!"

Baseline
3 Rnds
15 Bench Press (40% 3 RM)
20 Plyo Push Ups (clapper push ups w/o clap...just "jump" hands off ground @ top)
50m Buddy Pull*

Suicide Balls
10 RFT ~
15 Wall Balls
1 Suicide Run (10m-20m)
Run is run to 10m & back, then 20m & back!

* this is the culprite that caused the hydrogen ions to spill (legs burning, gut feeling like you will puke)

BTW ~ if you keep pushing yourself, you WILL puke... That is the body trying to get rid of the waste product (increased proton accumulation) after the ATP splits!
