When muscles are working hard and not enough oxygen is available the Kreb's cycle shuts down and the end product of glycolysis, pyruvic acid gets converted to lactic acid.
The muscles build lactic acid when you're doing strenuous exercise.
gets ur muscles tight
Lactic acid
Lactic acid.
It is caused by a buildup of lactic acid due to fermentation in the muscles. This is what is described as "the burn" when exercising.
Answer: Lactic acid gets into our muscle through lactic acid fermantation. Fermantation is getting a cell energy without using oxygen.
After a while of swimming, your muscles use lactic acid. It uses it through Lactic acid fermentation. It results in more energy.
that burning sensation is the lactic acid building up in your muscles when your muscles produce lactic acid the start to burn thats why you get the sensation
The heart rate increases to supply more lactic acid to the muscles for anaerobic respiration.
Lactic acid causes muscles to ache
Lactic acid settling in the muscles
When exercise begins the rate at which blood is circulated around the body increase by heart rate increasing. Lactic acid is a metablolic byproduct which circulates whithin the blood, when exercise begings the concentration of lactic acid begings to increase. When blood is pumped to working muscles , lactic acid begins to oxadise. Without the oxidisation of lactic acid muscles can begin the fatique in the muscles. The athlete will eventually have to stop exercise or even reduce the intensity. - The model above explains that with an increase in heart rate results in a more readily supply and circulation of blood to and from the working muscles. This increase is only possible if heart rate increase therefore benefiting the players game. This is only one benefit of an increase in hear rate to a players game.
