During HIIT, the Cori cycle helps muscles continue to work by converting lactic acid into glucose, which is then used for ATP production, thus sustaining energy and reducing muscle fatigue.
The Cori cycle plays a crucial role in energy production during high-intensity interval training (HIIT). When muscles engage in intense activity, they break down glycogen to produce energy, resulting in the accumulation of lactic acid. The Cori cycle aids by converting this lactic acid into blood lactate, which is then transported to the liver.
In the liver, lactate is converted into glucose through gluconeogenesis, which is then released back into the bloodstream. The glucose can be taken up by muscle cells again, allowing for continued ATP production and energy generation. The cycle is essential for regulating blood sugar and for the elimination of lactic acid, thus preventing muscles from becoming too acidic and fatigued during high-intensity activities, like HIIT.
The Cori cycle effectively recycles lactate produced by muscles during high-intensity exercises, maintaining energy supply and reducing fatigue, which allows for sustained muscular activity.
