8 Questions
What is the primary function of the lactic acid (LA) energy system?
To break down glucose to provide energy and resynthesize ATP
What is the duration of the LA system during high-intensity short-duration anaerobic activity?
2-3 minutes, but can last up to 30 seconds if exercise is flat out to exhaustion
What type of sports or activities primarily utilize the LA energy system?
High-intensity activities from 10-180 seconds, such as 400m sprint, 50m-100m swim, and midfield games
What is the advantage of the LA system in terms of ATP synthesis?
Resynthesizes two molecules of ATP, which is more than the PC system
What is the main limitation of the LA system?
The onset of blood lactate accumulation (OBLA)
What is the effect of lactic acid on enzyme activity?
It inhibits enzyme activity
How much of the potential energy is released by the LA system?
Only 5%
When does the LA system peak in terms of energy production?
At 1 minute
Learn about the lactic acid energy system, also known as anaerobic glycolysis, which provides energy during high-intensity, short-duration exercises. Discover how it breaks down glucose to resynthesize ATP without oxygen.
