Fitness tips: Understand the threshold of lactic acid (anaerobic)

Latate threshold, also known as the anaerobic threshold, onset of blood lactate accumulation point (OBLA).

Latate (anaerobic) threshold: When the intensity of exercise increases, anaerobic metabolism becomes the critical point of the main source of energy (or mainly rely on the anaerobic machine rotation).

This is an exercise intensity. If above this intensity, the body's energy source uses anaerobic acanthosis as the main energy supply method. The energy supply speed is fast but the efficiency is poor.

1. Generally, when the blood lactate concentration is close to 4 mmol/L.

2. Lack of training may be the maximum oxygen intake 40%, and endurance athletes with training experience can reach 80% to 90% of the maximum oxygen intake.

Generally speaking, the lactate threshold is one of the effective indicators for judging a person's aerobic exercise ability. When exercising at an intensity below the lactate threshold, the exercise he performs is called "aerobic exercise". When exercising at an intensity above the lactate threshold, there is "aerobic exercise".

After training period, the lactate threshold will increase. Generally speaking, the lactate threshold of trained athletes is higher than that of ordinary people, and the closer they are to the maximum oxygen intake.

3. When the intensity does not exceed the lactate threshold, they can exercise continuously for a long time without discomfort or fatigue; when the lactate threshold exceeds the lactate threshold, they begin to metabolic acidosis with the system (systemic metabolic Acidosis) is related, and at the same time, it greatly increases the demand for ventilation, and then becomes fatigued and unable to continue exercise.

The level of the anaerobic threshold depends on your exercise level. If your lactate threshold is higher and your anaerobic endurance is better, and your opponents on the field have begun to accumulate fatigue, slow judgment, and your technical level has declined, you are still dominating the rhythm of the game.
